Resistance Training To Failure Essay
Resistance training until failure was first introduced during World War II as a way to speed up injury rehabilitation of soldiers. (Sampson, 2015, p.
1) Several studies have suggested repeating an exercise to the point where neuromuscular system can no longer produce adequate force to overcome a
specific workload. Training to failure acutely causes motor damage but in turn causes increased motor unit recruitment, elevates mechanical stress.

I have organized the client's training program with the major muscles first in the program after that I would repeat the muscles again. In addition,
since the client had requested for 6 resistance training days I have strategized by splitting the major muscle groups into several days as seen in the
client's program. Furthermore, with having 6 days of resistance training it would be tough but with a mixture of upper and lower body days it would
allow the client to recovery and build the muscles. Not only, he would be build muscles, he would improve in his speedball games.

Resistance Training Essay
Resistance training is an exercise that exploits progressive resistance movements, typically with free weights or weight machines, to build strength or
muscle endurance (Mood et al 2003). Weight training has become very popular in recent years and is now used for a variety of reasons including
performance enhancement, competitive weight lifting and to increase physical fitness (Mood et al 2003). Interval training involves a repeated series of
exercise work bouts interspersed with rest of relief periods. This is a popular method among athletes because it allows the athlete to exercise at higher
relative intensities during the work interval than are possible with longer–duration, continuous training (Heyward 2002). The intensity can vary from ...

It might be more appropriate to refer to this type of training as vo2 max or aerobic capacity training since the athlete trains at or very near the
intensity which demands vo2 max of the system (Daniels and Scardina, 1984). Interval training can be referred to in several different ways. Fox
(1977) refers to two types of interval training, low power output interval training and high power output interval training. High power output interval
training involves exercise and rest periods of less than one minute. Gibala and Mcgee (2008) refer to High intensity training. This generally refers to
repeated sessions of relatively short intermittent exercise often performed with an 'all out'. Minimum volume of High intensity training may be
necessary to increase VO2 peak. Alternatively, Astrand and Rodahl (1977) say that exercise bouts lasting 3–5 minutes each are the longest
recommended and are considered optimum for training aerobic processes. The purpose of high intensity training is to repeatedly stress the
physiological systems that will be used during specific endurance type exercise (Daniels and Scardina 1984) than which is required during a specific
activity. Intensity was the most important factor in producing improvements in aerobic power, regardless of level of exercise, duration frequency,
program length or initial fitness (Wenger and bell,

Ergogenic Aid Research Paper
Introduction
The use of ergogenic aids have been utilized in sports to increase work capacity, enhance physiologic functions, and improve exercise performance.
Athletes in all sport disciplines are looking for natural ways to enhance their performance in sport and gain a competitive advantage over their
opponents.
Creatine has been one of the most extensively studied and researched ergogenic aid used to improve exercise performance in sport.
Most research on creatine has focused on the effects of this supplement on the ergogenic benefits on anaerobic performance.
There has been minimal research done on the effects of creatine supplementation on aerobic performance. The effects of creatine on aerobic
performance are less well known and documented ... Show more content on Helpwriting.net ...

Creatine supplementation and peak power
Creatine supplementation has also demonstrated the potential to cause increases in peak power activities.
Peak power signifies the highest mechanical power that is generated during any 3 to 5 second period of an exercise test.
When creatine is combined with heavy–resistance training, increases in peak power were reported jump squat performance after the 12–week study.
Greater increases in jump squat peak power were evident after subjects had taken creatine over placebo subjects.
Peak power performance in jump squat had increased in sets three and four for the creatine subjects after the first week of supplementation.
Creatine subjects experienced the largest increases peak power at the end of the 12–week study.

Gymnasts Resistance Training
Resistance Training
According to Sleeper, Kenyon, & Casey (2012), for gymnasts core training is very important. Gymnastics is a sport that engages the muscles of the
entire upper and lower body. Along with training the rectus abdominis, transverse abdominis, and inner and outer obliques, strengthening the core
involves the stabilization of the pelvis (mid body), the shoulder girdle (upper body), as well as the spine (upper–mid/lower body). Bodyweight
exercises are the main type of training modality used by gymnasts to prepare for competitions (Behm, & Colado, 2012). Plyometrics are beneficial for
gymnasts because these dynamic and explosive movements allow the athlete to increase strength and speed which are both necessary in order to ...

Gymnasts can perform the stability ball pike, stability ball jackknife, slide plank, stability ball rollout, and front plank (Major, 1996). These exercises
will help the gymnast be able to hold positions need for competition for a long duration of time. Gymnasts can also perform pushups, handstand holds,
stand up on toe, stand toe raises, and bar dips to improve their muscular strength (Major, 1996). The exercises help improve individual muscles that will
be used during the sport (Major, 1996). They also include movements that are used during the completion as well. The assistant exercises not only will
help with movement, and strength, but will also help stabilize the joints (Major,

Essay on Muscle Hypertrophy
Strength training typically produces a combination of the two different types of hypertrophy: contraction against 80 to 90% of the one repetition
maximum for 2–6 repetitions (reps) causes myofibrillated hypertrophy to dominate (as in powerlifters, olympic lifters and strength athletes), while
several repetitions (generally 8 – 12 for bodybuilding or 12 or more for muscular endurance) against a sub–maximal load facilitates mainly
sarcoplasmic hypertrophy (professional bodybuilders and endurance athletes).[citation needed] The first measurable effect is an increase in the neural
drive stimulating muscle contraction. Within just a few days, an untrained individual can achieve measurable strength gains resulting from "learning"
to use the ... Show more content on Helpwriting.net ...

A small study performed on young and elderly found that ingestion of 340 grams of lean beef (90 g protein) did not increase muscle protein synthesis
any more than ingestion of 113 grams of lean beef (30 g protein). In both groups, muscle protein synthesis increased by 50%. The study concluded that
more than 30 g protein in a single meal did not further enhance the stimulation of muscle protein synthesis in young and elderly.[8] However, this study
didn't check protein synthesis in relation to training; therefore conclusions from this research are controversial.
It is not uncommon for bodybuilders to advise a protein intake as high as 2–4 g per kilogram of bodyweight per day.[9][10] However, scientific
literature such as 'Evaluation of protein requirements for trained strength athletes (November 1992)' has suggested this is higher than necessary, as
protein intakes greater than 1.8 g per kilogram of body weight showed to have no greater effect on muscle hypertrophy.[11] A study carried out by
American College of Sports Medicine (2002) put the recommended daily protein intake for athletes at 1.2–1.8 g per kilogram of body
weight.[12][13][11] Conversely, Di Pasquale (2008), citing recent studies,

I like the change from the DC training and not having to push so far past failure. There will need to be an adjustment on the hypertrophy days as I over
estimated the amount of weight on some exercises and ended up not hitting the 12–15 reps per set. It was definitely a good change of pace and should
allow for better recovery up until the contest.
Monday 1/10/2011This week was a good week as far as weight loss goes. I was down 2 lbs. This puts me at 212.8 lbs. It was good to see the drop in
weight after such a low week last week. I not going to drop any calories this week and just stick to the same meal plan. I am also going to keep the

Introduction: The global nature of the obesity epidemic was formally recognized by a World Health Organization consultation in 1997(1). Prior
epidemiologic studies have yielded conflicting results regarding whether obesity is a risk factor for Atrial fibrillation (AF), but these studies were
potentially limited by short–term follow up and lack of echocardiography data(2). It is not sure if obesity itself predisposes to AF and so hypothesizing

The mean number of myonuclei per cross–sectional area of myofibres before training was 2.85 before training and by 90 days into training it averaged
2.82. Although, it was shown in the results that the mean value and SD for myonuclei at the end of the detraining period (2.99 В± 0.19) was higher
than pre–training values (2.85 В± 0.08). This study has shown that 30 days of resistance training is sufficient to induce an increase in satellite cells and
also that an additional 60 days of resistance training further increases the satellite cell amount. It is also shown, that the increase in satellite cell
numbers following resistance–training is maintained for >30 days once the training has stopped. Resistance training causes minor fibre damage and
results mainly in hypertrophy compared to the classical regeneration response of skeletal muscles such as myofibres necrosis. Overall, Kadi (2004)
summarised that the results of the study shows the flexibility of satellite cells in response to myotrauma, and has shown a good insight into the more
long term effects of heavy resistance training followed by detraining. The size and shape of muscle fibres when being targeted in the hypertrophic range
can still be achieved by only using the existing myonuclei within the muscles already, this means they can support the hypertrophy

Effects Training Has on Muscle Cell Hypertrophy
As discussed in paper one, readers can see the complexity that lies behind muscle fibers and the contractile units that make up each muscle cell. At the
normal physiology level, muscle fibers exist as complex bundles of small muscle filaments. These filaments, known as actin and myosin bind in such a
way that allows for sarcomere contraction. In assistance with calcium flowing into muscle cells, proteins known as tropomyosin and troponin
ultimately allow "cross bridging" to occur. Throughout the body three types of muscle fibers exist, these types of fibers are slow oxidative, fast
oxidative and fast glycolytic. Activation or recruitment of these fibers varies from person to person depending on the muscle specificity needed to
perform a given contraction. In other words the innervation of each fiber depends solely on the muscle needed to engage in a specific exercise. By first
knowing the anatomy behind a muscle cell one can then have a better understanding of the effects training has on muscle cell hypertrophy.
The two primary functions of skeletal muscle is to contract to cause force, and to provide stability to the body. During exercise each muscle must be
able to contract in response to the stress or tension on that muscle. The idea behind muscle hypertrophy is that as a progressive overload of stress is
applied to the muscle, it is able to adapt by increasing the size and number of contractile proteins making up the muscle fiber. Muscle growth or

A Brief Note On The Athlete 's Training Program Essay
Periodization in Bodybuilding
You may ask why the use of periodization in training programs? , well the goal of periodization is to help maximize what you gain of your training
while reducing the risk of getting injured in the long term. The way this is done is with an intelligently designed training year program that contains
smaller blocks of time that each has its specific goal and priority. This kind of overall schedule includes many aspects of an athlete's training program
and it may include specific training such as; strength training, conditioning, plyometric, and also any specific sport activities. However in this essay I
will specify the use of periodization in bodybuilding which is a sport that has become very popular in recent times.
What is Periodization?
In simple terms, Periodization is the planning and organization of training. When periodization is used in sport, it is usually used based on achieving
specific goals such as gaining maximal physical capabilities (strength, power, speed, etc...) for a given period of competition. For example in
bodybuilding, the training may be planned around a specific competition.
In bodybuilding periodization is not an unusual thing, in fact most bodybuilders "periodize" their training anyway and this is to reach their specific
goal whether it is to reduce body fat or bring up a lagging body part. Generally speaking, if you have an aim to reach a goal by a given time, then in
actual fact you are using periodization.
This is

Trunk Flexion
We found that the muscle strength of trunk flexion showed significant differences within group and between groups. The results of the trunk back
extension showed significant differences within group. Our result of increased trunk strength was similar to previous study results. Within group
difference of muscle activation was higher in the BLSE group than in the HLSE group. This implies that the EO and RA were activated as the
agonist of trunk flexion, and that muscle hypertrophy can increase strength of trunk flexion when activated by the EO and RA. One study showed
EO activated approximately 32% of MVIC by bracing and 12% of MVIC by hollowing (Grenier & McGill, 2007). The % EMG max values in RA was
18% in the bracing strategy, while the RA value was approximately 6% in the hollowing strategy(Maeo et al., 2013). Thus, we suggest that trunk
flexion strength would be increased by muscle hypertrophy if the bracing strategy is applied in side plank exercise and prone plank exercises, which
activate EO and RA, for 12 weeks.
In trunk back extension, the % EMG max value of ES was 20% in bracing group and 10% in hollowing group, ... Show more content on Helpwriting.net

HLSE and BLSE can be recommended as applicable and generalized exercises for the improvement of trunk strength and low back disability of
elderly women with NSLBP. Especially, HLSE, which leads to preferential contraction of TrA and was more effective in improving low back disability.
BLSE was more efficient in strengthening the trunk muscle through muscle hypertrophy of co–contraction of antero–lateral trunk muscles for 12
weeks. However, further, large scale clinical studies are necessary to identify the therapeuticeffectiveness of hollowing and bracing strategies; male
participants and broad age groups must be studied to increase power and to detect

Essay Comparing The Body's Physiological Responses To...
In comparing and contrasting the body's physiological responses to aerobic training and anaerobic training, one must first have an understanding of
aerobic and anaerobic training. Aerobic training involves exercising aerobically in order to improve your level of aerobic fitness. Over time as you
overload your oxygen transport and utilization systems, your body adapts to the demands that are placed upon it. Collectively, this process of overload
and adaptation is called aerobic training.
Physiological responses to aerobic training include lower resting heart rate which means increased efficiency of the cardiovascular system & faster
recovery; increased heart stroke volume per beat, by way of more full left ventricle during diastole; increased ... Show more content on Helpwriting.net

This involves the use of the ATP/CP and the glycolytic pathways to produce energy for the muscles. Usually short
–term and highly intense, this process
of using stored internal compounds without the use of oxygen from the blood is referred to as anaerobic training.
Physiological responses to anaerobic training include increase in the size and number of fast twitch muscle fibers; increased tolerance to high levels of
lactic acid; increase in glycolysis production due to increase in enzymes that breakdown glucose; increase in ATP, CP, creatine, and glycogen; increase
in testosterone and growth hormone.
As with most forms of training, aerobic and anaerobic training are similar in the fact that both increase in size and number the amount of mitochondria,
myoglobin, and capillarization, by way of muscle hypertrophy. In addition, both forms require the body to adapt and increase recovery abilities in
order to optimize training results. From the respiratory system's use or non–use of oxygen in delivering energy, to the digestive system's ability to
process more nutrients, to the endocrine system's ability to regulate hormonal output for more efficient energy usage and tissue growth, both training
methods are vital to the body's growth and development. Both benefit from muscle glycogen to fuel their

7 – HYPERTROPHY
Hypertrophy training is a very specific type of training. It is not a goal that all athletes may want to strive for. Hypertrophy training is training to
increase overall muscle mass and muscle size in the individual. Some athletes may wish to increase their physical size, but not necessarily to the size of
Arnold Schwarzenegger.
It is possible that if an athlete increases their muscle mass too much it will have a detrimental effect on their sport. A marathon runner, for example,
needs to strengthen their muscles and burn fat as it is easier to carry lean muscle mass. However,

Hypertrophy Essay
Hypertrophy "When a skeletal muscle is subjected to prolonged high resistance strength–training, it adapts by becoming larger and stronger. Maximal
voluntary strength is quite well related to the cross–sectional area (CSA) of the muscle" (Hakkinen, 1989). Researchers in previous studies make
mention of hypertrophy playing a role in the way different periodization models are effected. For example, endurance training differs from most type
of training because it has a high overall volume of the exercise being performed with low resistances, but with long duration. With this type of training
there is little or changes in muscle mass or strength (Gollnick, 1981). With linear periodization your first phase of the mesocycle is typically the

The majority of the studies lasted about 12 weeks this could be a drawback of the study because 12 weeks may not be long enough period to see clear
results. Some studies showed significant effects of UP in 6–8 weeks, and LP in the later weeks. For instance, Prestes (2009) "saw after 8 weeks, the
DUP group showed significant increase in the leg press 45 and arm curl maximal strength, which was not shown by LP group". Additionally, some of
the measurements used besides squat, bench, and leg press are vertical jump, seated medicine ball throw, loaded squat jump, standing arm curl, 8RM
bench press, 1RM lat pull and triceps extension.
In summary, this studied demonstrated that there is more research that needs to be done to find which method of periodization, undulating or linear
with increase gain in strength. What we can take from this study is the neuromuscular system is part of the strength process that should be taken into
consideration. Volume load/variation, density(recovery), hypertrophy all play a role in how the different periodization modes affect the way differently

Long-Term Effects Of Exercise On The Cardiovascular System
P4: describe the long–term effects of exercise on the cardiovascular and respiratory systems
Cardiovascular system
Cardiac hypertrophy is the enlargement, or thickening, of the heart muscle. After lots of strenuous exercise the heart muscle will increase. If a person
does exercise, a thirty minute jog every day, for six months there will be an obvious increase in many other factors but the heart muscles will have
grown in size. These changes are reversible when you discontinue aerobic training.
Stroke volume is the amount of blood pumped out of the heart during each contraction measured in mL/beat. A long term effect of exercise on stroke
volume is that it will increase. As the left ventricle grows in size, more blood can be filtered in and out.
Cardiac output is the volume of blood pumped by the heart per minute (mL blood/min). It is regulated ... Show more content on Helpwriting.net ...
After a long period of time the heart rate will decrease as the number of contractions will be less as the heart is bigger.
Capillarisation increases during long term exercise. Long–term aerobic exercise improves the elasticity of your blood vessels, or the ability of your
vessels to expand and contract. The improved elasticity delivers more oxygen and glucose to your muscles at a faster rate. The number of capillaries
in your working muscles also increases as an adaptation to long–term aerobic exercise.
Blood volume is the volume of blood (both red blood cells and plasma) in the circulatory system of any individual. A typical adult has a blood
volume of approximately 5 litres. The amount of blood circulating in your body increases within twenty four hours after your first exercise session.
An increase in blood volume means your body can deliver more oxygen to your working muscles. Your body will also be able to better regulate your
body temperature during

Neuromuscular Junctions
MUSCLE FIBERS AND EXERCISE:
Exercise leads to changes in muscle fiber size known as muscle hypertrophy, this increase in size is a result of increasing muscle fiber diameter caused
by exercise–induced genes, such as peroxisome proliferator–activated receptor gamma coactivator 1О± (PGC–1О±). (Ruas, White, Rao, Kleiner,
Brannan, Harrison; 2012). As per Balice–Gordon, Breedlove, Bernstein & Lichtman (1990) the Neuromuscular junction size is coupled, to a certain
degree, to muscle fiber size. In contrast to this, a study conducted on aged rats showed increased muscle fiber size in the soleus muscle with exercise,
but there was no increase in Neuromuscular junction size. Thus, some of the exercise–based changes of Neuromuscular junctions cannot ... Show more

vesicle clusters and receptor clusters. As studied by Gonzalez, de Cabo, Studenski, & Ferrucci (2014), the morphological changes together with
physiological alterations results in a remodeling of the motor unit and in a decline of the number of motor neurons, particularly the type II muscle fiber
(fast and glycolytic muscle fibers). These changes lead to excitation–contraction uncoupling, and a loss of communication between the nervous and
muscular system, causing a decline in skeletal muscle strength and muscle

Eight Ways to Improve Performance for Touch Football...
There are eight physiological adaptations that a touch football player would experience in response to training; these include a change in stroke
volume, heart rate, cardiac output, oxygen uptake, lung capacity, hemoglobin levels, muscle hypertrophy and the effect on slow– and fast–twitch
muscle fibers.
A touch football player would expect to experience the benefits of training after ten weeks. The first of these many benefits includes a change in stroke
volume. An athlete's stroke volume is the amount of blood that is pumped around their body in one beat. In response to training a touch football
player's stroke volume will increase both at rest and during exercise.
This increase is a result of the increase in the size of the heart, ... Show more content on Helpwriting.net ...
This decreased heart rate is just one of the physiological adaptations that a touch football player would experience as a result of training.
The third physiological adaptation that a touch football player would experience as a result of training is a change in their cardiac output. An athlete's
cardiac output is the volume of blood that their heart ejects per minute, and is therefore a direct result of the stoke volume and heart rate.
When untrained the touch football player's cardiac output may be around 20 litres per minute, as a result of training this reading would increase to
around 25 litres per minute. The formula for cardiac output is 'stroke volume x heart rate'. As previously discussed, the heart rate heart rate of a touch
football player would decrease as a result of training, whereas the stroke volume would increase.
The increase in cardiac output is therefore a result of an increase in stroke volume huge enough to slightly outweigh the decreased heart rate in the
equation. As a result of training a touch football player would experience a higher cardiac output, meaning that the body's cells are replenished more
regularly, thus improving the performance of the touch football player.
The fourth, and most significant, response to training that a touch football player would experience is a change in their oxygen uptake. Maximal
oxygen uptake, or max VO2, is considered by professionals to be the best guide for cardiorespiratory

LGMD: A Genetic Analysis
There are more than twenty subtypes of LGMD, each is classified according to the genetic flaws that appear to cause them. Fifteen genes that lead to
the production of muscle proteins have been identified as definite causes of LGMD when they are flawed. According to the Muscular Dystrophy
Association, "Type 1 LGMDs are dominantly inherited, requiring only one mutation for symptoms to result. Type 2 LGMDs are recessively inherited,
requiring two mutations – one from each parent – for symptoms to appear. Sometimes, LGMDs are referred to by their names, not their numbers, and
some types have not been assigned numbers." When one of these genes is faulty and protein problems arise, muscle cells and fibers do not function
properly. The muscles then... Show more content on Helpwriting.net ...
Onset of this disease occurs in adulthood. Symptoms associated with this disease include weakness and atrophy in the hip, thigh, and calf muscles,
with the symptoms often being asymmetrical. This disease usually has a low progression rate and does not include cardiac or respiratory involvement
(Institute of Genetic Medicine, 2007).
LGMD2M is an autosomal recessive form of LGMD caused by mutations on the Fukutin protein. Onset of this disease typically occurs in childhood.
The symptoms presented include weakness and wasting in the muscles of the hips, thighs, and shoulders. The cardiac and respiratory muscles may be
involved. There have been few cases of this type of LGMD described, but the gene involved is also associated with a severe form of congenital
muscular dystrophy (Institute of Genetic Medicine,

Hypertrophy And Absolute Strength
Hypertrophy refers to the muscle growth in addition with an increase in the size of the muscle cells. The development of hypertrophy is critical
amongst both Rugby league and Boxing. Rugby league players must develop absolute strength in order to accomplish tackles with force, resist these
tackled and henceforth be resistant in developing an injury. To accomplish this strength, resistance training in the way of weight training with free
weights would be efficient for a Rugby league player to advocate as it would help encourage hypertrophy to the athletes targeted muscle group through
specific exercises. These exercises must ensure large resistance with minimal reps for the process of hypertrophy to occur. For example a rugby league
player could

Pre-Training Nutrition Essay
Not only can pre–training nutrition optimize training to maximize output, but without proper nutrition post–training benefits will not be seen, as it is
essential the body is properly fueled to supply the metabolic processes for recovery, growth, and preparation for the next session. In this section,
post–training nutrition will use carbohydrates, omega–3 fat source, protein, and creatine to maximize metabolic adaptations to overcome the metabolic
stresses from training with the goal of overcoming both bone and muscle breakdown for increased synthesis, and preparing the bodies energy stores for
the next bout.

Muscle glycogen storage is an essential source utilized during resistance training, as the glycogen stored can be readily metabolized and used for
ATP production in the cytosol and mitochondria, where the stored glycogen can provide ATP three times as rapid due to the proximity to the site of
contractions within the muscle cells (Candow, 2017b). During muscle contractions, like ones produced during resistance training, muscle glycogen
stores are utilized first as the primary source of glycolysis for ATP production, but as stores deplete the liver is able to metabolize glycogen through a
process of glycogenosis to help maintain blood glucose levels and can be utilized by the muscle. During repeated contractions and movement during
resistance training, the muscle is able to absorb the glucose into the muscle cell rapidly due to the specialized transport proteins, GLUT–4, where
increased contractions and movement results in increased recruitment of the proteins (Candow, 2017b). In order for muscles to be able to metabolize
ATP utilizing muscle glycogen during exercise it is essential muscle glycogen stores are filled post exercise in order to sustain high performance and
duration of the next performance. Without proper replenishment, specifically the muscle glycogen stores, post exercise, the output of hepatic glucose
decreases at every level of intensity, negatively effecting both intensity and duration sustainability over

Myostatin Protein Analysis
The myostatin protein binds to an operator and prevents the gene for muscle growth from being expressed. (Joulia–Ekaza & Cabello 2006)
The protein also maintains a stable equilibrium of the muscles in adults. (Joulia–Ekaza & Cabelloa 2006)
When the MSTN gene, the gene which encodes myostatin, is deleted the fat and skeletal muscle mass within the organism is affected. (Joulia–Ekaza &

This raises questions as to what its role is in the muscle wasting during aging. (Joulia–Ekaza and Cabello 2007)
It was discovered by McPherron et al 1997 that the inhibition of the myostatin gene might have important applications for human diseases and the
genetic manipulation of farm animals. (Lee 2004)
Just like cattle, the human myostatin gene is located on the human chromosome 2. (Lee 2004)
Future studies need to be done to determine if manipulating the myostatin pathway will actually benefit humans in term on degenerative diseases. (Lee
2004)
Manipulation of the myostatin pathway will not only affect degenerative diseases, but it can also help with obesity and type II diabetes. (Lee 2004)
However, it is a concern that if the myostatin activity is inhibited that the surrounding amount of satellite cells will rapidly deplete which reduces the
ability of the muscle to regenerate. (Lee 2004)
Just like mice, the natural mutation will lead to a failure in fat accumulation which will further lead on to deal with abnormal fat accumulation. (Lee

Cardiovascular System Papers
CARDIOVASCULAR SYSTEM
The cardiovascular system is also known as the circulatory system, which is an organ system that encompasses the heart and blood vessels of the
body. The heart and blood vessels of the circulatory system adapt to repeated sessions of exercise in number of ways, the cardiovascular system carries
blood, oxygen and nutrients to the organs and tissues of the body and carries waste products and carbon dioxide from these tissues to be removed from
the body.
CARDIAC HYPERTROPHY
When you exercise regularly over a long period of time your heart will increase in size and volume. The ventricle walls will get bigger and thicker
allowing you to make bigger and powerful contractions. A common cause of cardiac hypertrophy is high blood pressure (hypertension) and heart valve
stenosis.
INCREASED STROKE VOLUME
It's the amount of blood pumped by the left ventricle, which occurs in one beat. A person who exercises on a daily basis will increase the stroke
volume allowing more blood to be pumped than a person who does not work out. Cardiovascular training is used to increase stroke volume. The more
blood that is pumped from the heart with each ... Show more content on Helpwriting.net ...
Which means that when you are at a resting point you won't need to use as much oxygen as you use while exercising. This means that individuals
become more efficient at using oxygen which means not as much wastage. The reason that the body adapts this is because if you exercise regularly
your body is getting used to exercise on a regular basis which then will start to use less oxygen. Also our heart rate will be able to decrease because
when we stop exercising our heart will start to recover, which leads to a decrease in heart rate. For example this benefits the athletes because a quicker
decrease in resting heart rate is an indicator that your heart is efficient at transporting oxygenated blood through your body with each

The Mission Of A Strength And Conditioning Program
The mission of a strength and conditioning program is to elevate the physical capacities of an athlete, allowing him to express his full technical and
tactical potential on the field. To do that, we must therefore develop a systematic approach toward the physical conditioning of the athlete. Maximum
force, power, aerobic capacity, aerobic power and elastic anaerobic power are of prime importance in football. Those are the variables that must be
developed.
Periodization is probably the most important concept in strength and conditioning for football. The concept of periodization is based on Hans Selke 's
general adaptation theory. This theory suggests that there are three body adaptation phases to a given stress:
The first one is the shock; when the body is exposed to a training stimulus, there is micro–cellular damage and performance decrease (fatigue).
The second phase is stimulus adaptation; a process where physiological adaptations take place and performance increases (super compensation)
The third phase is the stagnation phase, the body has adapted itself and is used to the stimulus. Consequently, there 's no new adaptation. Also, when
there is too much time without stimulation, there is a decrease in performance.
Therefore, we must plan variation in the yearly physical training of the football player: variation in training volume, intensity, type of exercise and type
and speed of contraction.
We will set up a training schedule over a period of time and organize it into

Overtraining Training Essay
How often do you train each muscle group?
Training frequency is one of the most misunderstood variables by athletes aiming to improve muscle strength and size. Many athletes believe that
training any body part more than once or twice per week will result in overtraining and muscle loss. This type of black and white thinking can be a
limiting factor in an athletes' development. In fact, there is a growing body of evidence showing a greater benefit to increased training frequency when
used correctly.
To begin with, it is important to define the difference between "overreaching" and "overtraining." Overreaching often leads to a short–term decrease in
performance that can be recovered from in a few days. Overtraining–which is actually an extremely rare occurrence–occurs when it takes weeks or
months to recover. (Fry, 1997) Moreover,... Show more content on Helpwriting.net ...
Many people would be quick to suggest that this training program is a recipe for overtraining. However, the researchers actually found that the
participants in the study experienced massive gains in strength and hypertrophy. (Raastad, 2012) Resistance training stimulates muscle protein synthesis
so the results of this study are not particularly surprising. Research has shown that MPS (muscle protein synthesis) reaches baseline around 36 hours
after resistance training. (MacDougall, 1995) Furthermore, research has shown that muscle protein synthesis can return to baseline in as little as 16–24
hours in well–trained athletes. (Kim, 2005) So, if you only train each body part once per week, you really only stimulate muscle protein synthesis for
16–36 hours. If you want to bring up a lagging body part or increase your strength on a certain lift, why would you stop there? Why not stimulate
muscle growth 3 or more times per

Neuromuscular Junction Essay
EFFECT OF EXERCISE TRAINING ON NEUROMUSCULAR JUNCTION MOLECULAR PATHWAYS:
The benefits of physical exercise for humans are known for many years and physical training can interfere positively in the up regulation and protein
expression of several molecules and growth factors. Firstly, the physical exercise can alter the expression of Glial cell line–derived neurotropic factor
(GDNF) differently in slow and fast muscle fibers, and thereby affect peripheral motor neurons. Wehrwein, Roskelley & Spitsbergen (2011) showed

Nt-Probph Case Study
Introduction
N–terminal prohormone of brain natriuretic peptide (NT–proBNP) is an inactive byproduct of brain natriuretic peptide (BNP). They are released from
myocytes after the prohormone BNP (ProBNP) is cleaved into the NT–proBNP and the BNP. The synthesis of ProBNP and the release of NT–proBNP
and BNP are caused by cardiac wall stress including stretching, ischemic and/or hypoxic stimuli of myocytes. Although NT–proBNP is not the active
polypeptide product, it is less labile and possesses a longer plasma half–life compared to active BNP. Therefore, NT–proBNP has been used as a stable
marker of BNP. Measuring the plasma concentration of NT–proBNP has been used to assist diagnosing various cardiac diseases in humans and other

Pathological and echocardiographic examination of the LVH–affected rhesus macaques revealed the similar characteristics shared between HCM in
humans and LVH in rhesus macaques. Plasma Troponin I concentration was measured in some of the LVH

the study failed to show the association between an elevation of Troponin I concentration and the presence of LVH. However, no study has been
performed to compare the plasma concentration of NT–proBNP in the rhesus macaques with LVH and controls. The purpose of the present study is to
compare the concentrations of NT–proBNP in rhesus macaques with LVH and controls using commercially available ELISA kit. Associatin between
the NT–proBNP concentration and various features of LVH including left ventricular wall thickness will be also be evaluated. We hypothesized that
rhesus macaques with LVH show higher concentrations of NT–proBNP attributed to the hypertrophied ventricular walls with diastolic dysfunction, and
the severity of left ventricular wall thickness is associated with the plasma NT–proBNP concentration.

Make sure your feet are as far apart as your shoulders. Always keep your knees bent a little. Don't rush your movements and always count to four,
pause for a second, and return to your beginning position.
Don't forget to breathe the right way, too. You should never hold your breath while doing these training exercises. Instead, take a deep breath when you
lift and let it out when you release the weight.
Make sure you have a routine that is going to work all of the muscle groups you want to hit during that session.
Always do the exercises while you are standing or sitting
Don't try to impress anyone by lifting more weight than you can. If you can't do the prescribed number of repetitions outlined in a workout program,
then you need to stop and choose a lighter weight.

What Causes Muscle Hypertrophy?
What Causes Muscle Hypertrophy?
It has been said it is not where you start but where you finish. In the sport of weight training there is no finish. Individuals are constantly striving to
get bigger, stronger and faster. All bodybuilders have made an effort to put on muscle mass. However, even individuals who get paid to buildmuscle as
a profession, had to have been small at one point. The question is what causes muscle hypertrophy? The answer... is progressive overload of the
muscle. Muscle hypertrophy is caused by enhancement of the muscle fibers and muscle cells; which in laymens's terms, means tearing a muscle fiber
so that it may grow back bigger and stronger. There are three significant factors that play a substantial role in muscle building. Training, nutrition, and
recovery are the key disciplines that allow weight lifters to reach their desired physique and turn the image in their mind, to the reflection in the
mirror. Before diving into factors that cause muscle hypertrophy, an explanation of what hypertrophy does to the body. Scientists often break
hypertrophy down into two types: "Sarcoplasmic hypertrophy increases muscle size by increasing the volume of sarcoplasmic fluid in the muscle cell.
Myofibrillar hypertrophy (sometimes called "functional hypertrophy") increases muscle size by increasing the contractile proteins" (All about Muscle
Growth). It is a form of recovery, where the body tries to adapt to the muscle tears and vigorous stress it has been put

Researchers in Australia looked at approximately 1,700 men from ages seventy and older with their likelihood of experiencing a fall over a four–year
period. There were more than 2,700 falls during the study, but the men who swam had a thirty–three percent less likely chance to fall compared to all
the men in the study (Rowan).
Running is also amazing because it helps prevents a surplus of diseases like: stroke, diabetes, high blood pressure, high cholesterol, and blood
clotting. Running helps prevents diabetes because it helps maintain a balanced amount of carbohydrates and sugar in the blood (Rowan). As I
stated in my proposal, I think that a mix of aerobic and anaerobic exercise is the best for people of older age. I say this because anaerobic exercise
builds muscle and stronger bones, and aerobic exercise promotes better blood flow and strengthens the heart and lungs. It is important to maintain
strength in muscles and bones as the body ages because each year 2.8 million older people are treated in emergency departments for fall injuries.
Falls are very dangerous and sometimes fatal. They cause broken bones and serious head injuries. If someone were to be injured by falling in their
older age, they would be hospitalized, and if the injury was serious enough, could even die (Important Facts About

Circuit Conditioning Is A Workout Scheme
Tabata circuit conditioning is a workout scheme which was founded by Doctor Izumi Tabata from the National Institute of Sports and Fitness in
Tokyo, in 1996 (Tabata et al., 1996). The first stages of the Tabata circuit began in the midst of coaching the Japanese speed skating team as he
conducted a study using an interval based training model (Tabata et al., 1996). The main objective of the research conducted in 1996 was to identify
whether it was possible to improve the performance of his elite levelled skating team by using a certain protocol. As a result, Doctor Izumi was able to
create a time efficient workout which "builds muscle, burns fat and increases VO2 max'' (Tabata et al., 1996). The workout is a combination of eight
short repeated exercises which last a total of four minutes. The eight intervals are broken down into twenty seconds of intense exercise, followed by a
ten second rest (Tabata et al., 1996). With academic evidence, this literature review will analyse Tabata circuit and establish how it has progressed from
use for aerobic training to then into a workout.
According to the American council on exercise (2016), "An effective cardiovascular and muscular–conditioning program can be accomplished in a
short period of time, but only if the level of intensity is extremely high". Dr Tabata uses this technique in his infamous Tabata workout scheme.
Furthermore, tabata implemented this as he created his training experiments. The first experiment was to pedal on an

Tendon Exercise
The larger is the cross–sectional area of a muscle, the higher is the muscular force production and the larger is the stress on a tendon (Wang, 2006).
Therefore, tendon cross–sectional area correlated well with the physiological cross–sectional area of associated muscles (An, Linscheid and Brand,
1991). A well designexercise program, may have the potential to increase tendon cross sectional area which in turn, will allow the tendon to support
high level of stress.
Evidence has shown that physical training induce hypertrophy and improved stiffness of human tendons (Kongsgaard et al., 2005; Kongsgaard et al.,
2007). Tendons exhibit increased cross–sectional area and tensile strength, and tendon fibroblasts increase the production of collagen type I as a result
of appropriate physical training (Wang, 2006).
In contrast, excessive mechanical loading is considered a major causation factor in the development of tendon patologies. It is thought that small,
repetitive strains, which are below the failure threshold of the tendon, cause tendon microinjuries and may lead to tendon inflammation. According to
Wang (2006) tendon inflammation due to the production of PGE2 and LTB4 in response to repetitive mechanical loading may contribute to the
development of tendon degeneration. ... Show more content on Helpwriting.net ...
(2009), a well–structured, long–term exercise, within a physiological range, does not harm the tendon but actually reinforces it, stimulating the
production of new collagen fibers. When tendons are injured, the body initiates a process of healing and scar formation that can be divided into phases:
1) Hemostasis/inflammation, 2) Proliferation/fibroplasia and 3) Remodeling/maturation (Figure 1). First, collagen molecules assemble extra–cellularly
in close association with the fibroblasts to form immature fibrils. Then, the fibrils assemble end to end to form longer fibrils. In a third step, fibrils
associate laterally to generate large diameter fibrils (Abate et al.,

Why Do Athletes Use Resistance Training?
Resistance training involves the use of static and dynamic muscle movements with the tension of an external load. Resistance training (RT) is widely
used to elicit muscle hypertrophy and increases in muscle strength with the objectives of enhancing performance such increased muscle force, increased
muscle mass and power (McGuigan, Wright, & Fleck, 2012). Athletes use resistance training in many aspects to aid their performance in particular
sports, such as making them a faster, stronger and more powerful athlete. Resistance training leads to neural and hypertrophic adaptations responsible
for improved strength, neural adaptations occur such as increased motor unit recruitment and increased motor unit firing frequency. These neural
adaptations ... Show more content on Helpwriting.net ...
In a study by Hakkinen, (1989) it states that "during stressful periods of a strength/resistance training program the level of biologically active unbound
testosterone as well as the balance between the androgenic–anabolic activity and the catabolizing effect of glucocorticoids may be more important for
the trainability of muscular strength". Other studies have also shown that the level of free testosterone may be important for trainability (Hakkinen,
Pakarinen, Alan, & Komi, 1985). With resistance training, muscle hypertrophy usually occurs due to the stress on the body. The process of
hypertrophy results in an increase in the synthesis of the contractile proteins actin and myosin within the myofibril and a growth in the number of
myofibrils within a muscle fibre. The new myofilaments are then added to the external layers of the myofibril resulting in an increased muscle
diameter (Verdijk et al., 2009). Testosterone is also beneficial to muscle hypertrophy, which can help muscle strength as the bigger the muscle size, the
more likely it will produce greater

What is Muscle Hypertrophy?
Muscle hypertrophy refers to muscular enlargement resulting from resistance training, On the cellular level muscle hypertrophy is increased by the
expansion of cross–sectional area of the existing muscle fibers. (Goldburg, 1973) The adaptation of muscle in the world of strength and conditioning
can give an athlete the potential to become bigger, faster, and stronger. Since being big, fast, and strong is an advantage in many sports, this means that
much of the time that a strength and conditioning coach has revolves around the goal of getting their athletes to see muscle hypertrophy. On just one
level this desire is a driving force behind the large amount of research and competiveness in the industry to produce extremely high level college and
professional sport athletes. Exercise physiologists conduct research studies and form experiments so they can test new techniques in exercise so they
can better understand and optimize muscular hypertrophy. Traditionally, the American College of Sports Medicine recommends resistance training
using intensities 70% of 1–repetition maximum (1RM) because it seems to elicit the greatest increases in skeletal muscle size and strength (ACSM,
2002). More recently, low–intensity resistance training in combination with blood flow restriction (LI–BFR) has been shown to increase muscle size
and strength using only 20–30% of an individual's 1RM (Karabulut, 2010). This type of training method also referred to as the KAATSU training
methodology was

Answer. Strength training or resistance training is a type of exercise referred to as low frequency high force output activity. Physical activities includes
lifting free weights and using resistance machines. During initial stages of strength training functional improvements increase beyond the expectation.

Pre Vs Post Workout Analysis
The research article that I will be summarizing is Jose Antonio and Victoria Ciccone's, "The effects of pre versus post workout supplementation of
creatine monohydrate on body composition and strength." The purpose of this article was to study if taking creatine pre or post workout had if any
effects and whether which of the two times was best to take creatine. I was drawn to this particular article because I've recently started to work out
more regularly for strength and muscle growth. Because of this I want to gain more knowledge on what supplements such as creatine, which will best
benefit me in building more mass.
The participants taking part in this experiment were nineteen male recreational bodybuilders. They were healthy college–age students with a year of
regular resistance training (Antonio and Ciccone 2). They were instructed to stop taking any workout supplements or ergogenic aids four weeks prior
to the study (2). My interpretation of this choice, is that they wanted to minimize the outcome of any discrepancies appearing in the data as much as
possible. Participants were randomly placed into two groups, PRE–SUPP or POST– SUPP. The abbreviations indicated when the 5 grams of creatine
monohydrate would be consumed by the participants depending on what group they were in. The participants followed a "periodized, split–routine
