Muscle hypertrophy is an increase in the size of skeletal muscles due to muscle cells becoming larger. It occurs through two processes: sarcoplasmic hypertrophy which increases glycogen storage and myofibrillar hypertrophy which enlarges muscle attachments and tissues. Bodybuilders and athletes use strength training, diets, and supplements to promote muscle hypertrophy through both pathways to develop uniquely large muscles, though no two people experience identical growth.

Neuromuscular adaptations to training
This document summarizes the neural and muscular adaptations that occur from resistance and aerobic training. It discusses how the central nervous system adapts through improved motor unit recruitment. Resistance training causes muscle fiber hypertrophy and increases in strength, while aerobic training improves aerobic capacity without enhancing muscle size. Both can promote a fast to slow shift in fiber types. Connective tissues like tendons and ligaments strengthen through increased collagen from high intensity loading. Bone modeling occurs when forces exceed threshold levels, stimulating new formation.

Muscular hypertrophy
Muscle hypertrophy is an increase in muscle size through growth of muscle cells. There are two types: sarcoplasmic hypertrophy which increases fluid volume but not strength, and myofibrillar hypertrophy which increases contractile proteins and adds strength. Factors that cause hypertrophy include microtrauma, muscle recruitment, nutrition, mitochondria, myoglobin, growth hormones, gender, and genetic responses. Older age decreases healing and immunization while greater microtrauma and recruitment lead to more growth. Increased protein intake and mitochondria provide more energy for growth. Males tend to have more due to hormones like testosterone. Contraction of contractile proteins may also promote hypertrophy but the mechanisms are still
Strength and the muscular system
This document discusses the muscular system and strength training. It explains that muscles work with connective tissues like tendons, and describes the series elastic component (SEC) and parallel elastic component (PEC) of the muscle model. The document also discusses the different types of muscle contractions (isometric, concentric, eccentric), muscle actions like agonist and antagonist muscles, and the importance of the nervous system in strength and muscle development. Functional strength training aims to improve abilities like speed and endurance, while structural training focuses more on muscle hypertrophy.
Muscle hypertrophy
Muscle hypertrophy is defined as an increase in the size of a muscle through an increase in the size of its component cells. There are two main types of hypertrophy: myofibrillar hypertrophy and sarcoplasmic hypertrophy. Myofibrillar hypertrophy increases muscle strength through adding more actins and myosin contractile proteins, while sarcoplasmic hypertrophy increases muscle size through added sarcoplasmic fluid but does not increase strength. Causes of hypertrophy include microtrauma to muscles from exercise, adequate muscular nutrition and protein intake, recruitment of more muscle fibers, genetic responses, and factors like age, gender, and levels of hormones like testosterone and growth hormone.
Hypertrophy training
This document discusses muscle hypertrophy, or muscle growth. It explains that hypertrophy occurs through an increase in the size of existing muscle fibers and number of myofibrils. Higher training volumes with moderate-heavy weights and moderate-high repetitions per set performed over multiple sets is associated with hypertrophy. Short rest periods between sets allows for higher training volumes. The document recommends compound exercises that recruit more muscle mass and hormonal response, as well as isolation exercises, performed over multiple training sessions per week for optimal hypertrophy.
Hypertrophy:Basics and Advanced methods
the lecture is about mechanisms of hypertrophy and training methods to maximize hypertrophy or muscle mass. training variables have been discussed as well as adaptations to eccentric training.
Microsoft power point explain energy source and muscle metabolism
The document discusses muscle metabolism and energy systems. It explains that ATP is the immediate source of energy for muscle contraction. There are three main energy systems: 1) the phosphocreatine-creatine system provides energy for brief, intense bursts through the breakdown of phosphocreatine and resynthesis of ATP, 2) the glycolysis system breaks down glycogen anaerobically to produce ATP through lactic acid formation, sustaining moderate activity for 1-2 minutes, and 3) the aerobic system oxidizes fuels like glucose and fatty acids through mitochondrial respiration to continuously produce ATP, sustaining lower-intensity activity. Together these systems support varying levels of muscular activity.

Physiological adaptations in response to aerobic training
The document discusses several key physiological adaptations that occur in the body in response to aerobic training, including decreased resting heart rate, increased stroke volume and cardiac output, improved oxygen uptake, and enhanced efficiency of the cardiovascular and respiratory systems. It also notes some gender differences in lung capacity and muscle mass as well as effects on blood pressure, haemoglobin levels, and muscle fiber composition between aerobic and anaerobic training.
Effect of exercise on CardioVascular System
1. During exercise, the body undergoes adjustments to supply nutrients and oxygen to active tissues and prevent overheating.
2. There are two types of exercise - dynamic exercise involves muscle movement while static exercise does not.
3. Exercise can be aerobic, using oxygen for energy over long periods, or anaerobic, using glycogen without oxygen for short bursts.
4. The cardiovascular system responds to exercise through increased heart rate, cardiac output, and blood flow to muscles to meet energy demands, while blood pressure rises with intense exercise but falls below resting after as metabolites accumulate.
Chronic Adaptations To Training
Chronic training adaptations occur through long-term physiological changes in response to training loads. Aerobic training increases cardiovascular endurance through increased stroke volume, capillarization and mitochondria. Anaerobic training increases strength and power through increased contractile proteins, glycogen stores, and glycolytic enzymes. Both training types cause muscular hypertrophy but through different fiber recruitment patterns.
Types of Skeletal Muscle Fibers
This document discusses the three main types of skeletal muscle fibers:
1) Slow oxidative fibers (SO) are dark red, contain many mitochondria and blood vessels, generate ATP through aerobic respiration, and contract slowly but resist fatigue well. They are suited for endurance activities like marathon running.
2) Fast oxidative-glycolytic fibers (FOG) are also dark red but generate ATP through both aerobic respiration and anaerobic glycolysis. They contract faster than SO fibers but more slowly than FG fibers. They are suited for activities like walking and sprinting.
3) Fast glycolytic fibers (FG) are white, rely primarily on anaerobic glycolysis to generate

All about ATP(Adenosine Tri-Phosphate), how body gets energy from it (molecular formula) and its working in sports. Moreover Creatine Phosphate and Re-synthesis of ATP also know as ATP-CP system.(ATP-PC) (ATP-PCr) or Anaerobic system.
Muscular contractions
This document discusses the characteristics and functions of skeletal muscle. It covers common muscle features like nervous control, contractibility, and elasticity. It also describes the different types of muscular contractions including isometric, isotonic, eccentric, and isokinetic. Additionally, it explains how musculoskeletal movements are possible through muscle origin and insertion points and the roles of agonist, antagonist, fixator, and synergist muscles. Finally, it discusses muscle fiber arrangement, types, gender differences, and how the muscle system responds to physical activity.
Respiratory effects of exercise
Short term exercise increases breathing rate and depth to deliver more oxygen to the lungs and remove more waste products. It also increases tidal volume, which is the amount of air inhaled and exhaled with each normal breath. Long term exercise lowers resting respiratory rate and rate during exercise over time. It also increases lung volume and efficiency as well as blood supply to the lungs.
Active movement resisted exercises
This document discusses active movement and resisted exercise. It defines active movement as voluntary movement performed using one's own strength. Resisted exercise involves applying an external force in opposition to muscular contraction to increase tension and develop muscle power and endurance. The document outlines various techniques for resisted exercise, including proper positioning, stabilization, applying traction, and using the correct resisting force matched to the individual's ability. It recommends low resistance with high repetitions to develop endurance and high resistance with low repetitions to build power and muscle size.
Neuromuscular adaptation to exercise –application to practise
This document discusses neuromuscular adaptations to exercise. It explains that neural adaptations occur within the nervous system at the motor cortex, spinal cord, and neuromuscular junction in response to training. Neuromuscular adaptations include increases in muscle size, strength, mitochondria, and glycogen storage. The type and intensity of exercise determines the specific adaptations, with strength training increasing fiber size and endurance training increasing aerobic capacity. Neural adaptations differ by changing central drive and motor unit properties within the nervous system. Overtraining can cause extreme fatigue, illness or injury from insufficient rest between training sessions.

Chap19
Periodization involves systematically varying training variables over periods of time to optimize performance and prevent overtraining. It follows the general adaptation syndrome of stress response. The traditional model includes a preparatory period focusing on hypertrophy, strength, and power; a competition period for peaking; and transition periods. Sport seasons map to these periods. An example macrocycle progresses an athlete through preseason, in-season, postseason, and off-season mesocycles with appropriate training emphases. Periodization promotes long-term performance gains through planned variation in training load.
muscle fatigue
Muscle fatigue occurs due to prolonged and forceful muscle contraction which depletes glycogen stores. It results from the inability of contractile and metabolic processes to continue supplying work output. Transmission of nerve signals through the neuromuscular junction can also diminish with intense activity, further reducing contraction. Interrupting blood flow leads to near-complete fatigue within 1-2 minutes due to nutrient and oxygen loss. During heavy exercise above 70% capacity, skeletal muscle contracts and relaxes more slowly, requiring rest to restore normal function.
Muscle fibre types
This document discusses the different types of muscle fibers: Type 1 slow-twitch fibers, and Type 2 fast-twitch fibers including Type 2a fast oxidative glycolytic fibers and Type 2b fast glycolytic fibers. It aims to describe the structure and function of each fiber type, how recruitment patterns vary, and how fiber types can adapt to long term activity or detraining. The document also analyzes how different sports may require different fiber type compositions and discusses fiber type considerations like potential, training effects, detraining effects, and recovery needs.
04 cardiorespiratory adaptation to training
This document summarizes the cardiorespiratory adaptations that occur with endurance training. Key adaptations include increased heart size and strength, higher stroke volume, lower resting heart rate, increased blood volume and oxygen carrying capacity, enhanced lung function and oxygen diffusion, raised lactate threshold, and significantly higher maximal oxygen consumption. The degree of adaptation depends on factors like genetics, age, gender, and the specificity of an individual's training program. Regular endurance training can improve performance by reducing fatigue throughout exercise.
Respiratory adaptation to exercise
The document discusses several respiratory adaptations that occur with long-term exercise. These include increased lung ventilation through higher tidal volumes and breathing rates, increased lung capacity allowing greater expansion, strengthened respiratory muscles, more lung capillaries and alveoli for improved gas exchange, higher VO2 max, and an increased lactate threshold allowing harder exercise. Aerobic training especially improves gas exchange and VO2 max through cardiac and muscle changes, while anaerobic training strengthens respiratory muscles.
Exercise for special populations
This document provides exercise guidelines for several special populations, including those with cardiovascular disorders, hypertension, diabetes, asthma, cancer, osteoporosis, low back pain, and obesity. It also includes guidelines for older adults, youth, and general populations. The guidelines specify appropriate exercise modes, intensities, durations, and frequencies for each population, with a focus on gradual progression, safety, and addressing each group's unique medical needs or health risks. Communication with healthcare providers is emphasized.
MUSCLE FIBRES AND ITS SIGNIFICANCE.ppt
There are three main types of muscle fibers: slow-twitch (type I), fast-twitch oxidative (type IIa), and fast-twitch glycolytic (type IIb). They differ in their speed of contraction, fatigue resistance, and metabolism. Slow-twitch fibers contract slowly but are resistant to fatigue as they primarily use aerobic metabolism. Fast-twitch fibers contract quickly but fatigue easily, with type IIb fibers relying solely on anaerobic glycolysis. Aging leads to a loss of both fiber types but preferential atrophy of type II fibers. Physical therapy can target muscle fiber types through endurance or resistance training to improve performance.
Exercise physiology 8
This document discusses various aspects of muscle physiology and training principles. It defines key terms like muscle strength, power, endurance and different energy systems. It describes how muscle adaptations occur in response to different types of training like resistance, aerobic and anaerobic training. It also summarizes the cardiovascular, respiratory, muscular and other physiological adaptations that result from endurance training.
Muscular hypertrophy presentation
This document discusses different factors that influence muscular hypertrophy, or muscle growth. It states that to maximize hypertrophy, training should target all muscle fiber types by incorporating a wide range of rep ranges and loads. Higher volume through increased sets, frequency, and density is more important for hypertrophy than other variables, though overtraining can occur with excessive volume increases. Training to muscular failure can further enhance hypertrophy when work is matched, but should not be done continually to avoid overtraining. Genetics and use of steroids also impact hypertrophy but cannot be controlled. Proper nutrition is essential to support training adaptations.
Vo2 max
VO2 max is the maximum amount of oxygen the body can utilize during exercise. It is measured using equipment like a metabolic cart or treadmill along with a mouthpiece and nose clips. The measurement involves exercising to exhaustion while oxygen intake and carbon dioxide output are measured. VO2 max is important because it is the best indicator of cardiovascular fitness and aerobic capacity, though other factors also influence endurance. A higher VO2 max is associated with lower risk of heart disease. Coaches use VO2 max measurements to design effective training programs tailored to individual athletes' physiological capacities.
Blood Flow Restriction Therapy.pdfx
Blood flow restriction therapy uses elastic bands or tourniquets to restrict venous blood flow from leaving exercised muscles during low-intensity exercises, causing the muscles to be exposed to metabolic stress similar to high-intensity training. A case study found that using blood flow restriction during low-intensity bicep curls and triceps extensions led to greater increases in blood lactate, heart rate, and perceived exertion compared to the same exercises without restriction. While blood flow restriction allows for muscle gains with lower exercise loads, it can increase risks of delayed muscle soreness, thrombosis, and elevated blood pressure.
Disorders of growth. General Pathology
This document provides an overview of cellular adaptations and developmental disorders. It begins by defining cellular adaptations as reversible changes in cells in response to environmental changes, which can be physiological or pathological. The main cellular adaptations discussed are hypertrophy, hyperplasia, atrophy, and metaplasia. Causes, types, and examples of each are described. Developmental disorders summarized include hemifacial atrophy, hemihypertrophy, agnathia, micrognathia, and macrognathia. Key features and causes of each condition are highlighted. The document concludes by differentiating between congenital and hereditary conditions.

Satellite Cell
Satellite cell addition is not necessarily required for skeletal muscle hypertrophy based on several studies. Some studies have found that pharmacological agents, exercise, and irradiation can induce muscle hypertrophy without an accompanying increase in satellite cell number or DNA content. However, the role of satellite cells in hypertrophy remains debated as multiple studies have not adequately addressed factors like analysis time points and sufficient increases in muscle size. More research is still needed to conclusively determine if satellite cell addition is obligatory for hypertrophy in all conditions.

Kylee Burt took a yoga class once a week at Renew Yoga studio in Daytona Beach, Florida for her fitness course project. She enjoyed Hatha yoga classes as well as yoga on the beach classes. By sticking to her goal, she grew in her yoga practice and met others who also enjoyed yoga. Kylee found yoga to be relaxing and a way to stay in shape. She would recommend yoga to others.
Fitness Equipment
This document discusses three types of fitness equipment - treadmills, rowing machines, and elliptical machines. Treadmills allow you to run and adjust the incline for an intense cardio workout that works your legs and core, costing between $500-$5,000. Rowing machines provide a low-impact full-body workout for your legs and core through pushing yourself backwards with the legs and core while adjusting resistence, costing $300-$1,000. Elliptical machines combine the motions of a treadmill and stair stepper to work muscles in the legs, core, butt, and arms for a full-body workout, costing up to $1,000 depending on the model.
Last assignment
Kylee Burt tracked her personal fitness progress in a journal. Her initial goal was to do yoga 4 times per week, which she exceeded by also doing pilates workouts and sometimes yoga more than 4 times per week. Her new goal was to do a pilates routine with warm up and cool down at least 4 times per week, as well as go to the gym once per week for cardio. Kylee's resting heart rate was 53 beats per minute. She created F.I.T.T. workout plans for yoga and pilates and modified her plan over time to be more challenging by increasing frequency and adding cardio. Kylee's resting heart rate improved from 43 to 48, showing increased cardiovascular fitness.
Flexibility
Flexibility refers to the ability of muscles and joints to move through their full range of motion. Maintaining good flexibility is important for health as it can reduce injuries during physical activity, increase mobility, and help prevent back problems. Flexible muscles and joints are better able to reach their maximum range of motion, lowering the risk of sprains and tears when the body can stretch far enough for any activity.
Hypertension
Hypertension, also known as high blood pressure, is a chronic medical condition where the arteries have an elevated blood pressure. It is often asymptomatic but can cause headaches, dizziness, and fainting. Hypertension increases the risks of heart disease, arterial disease, strokes, dementia, and kidney failure. Nearly 45% of Americans have hypertension, and over 17% of hypertensive patients die from the disease or related complications. Maintaining a healthy weight, limiting sodium intake, regular exercise, and moderating alcohol consumption are effective ways to prevent hypertension.

3. Maintaining good nutrition and participating in regular exercise provides benefits like reducing disease risk, maintaining a healthy weight and metabolism, and improving performance for sports.
Exercise and Muscle
Physical exercise, particularly weight training, causes changes to the muscular system. Key changes include muscle hypertrophy, or an increase in muscle size and thickness. Chronic hypertrophy occurs with long-term weight training and causes an increase in total muscle protein and fiber size. Aerobic changes from endurance training include increases in myoglobin, mitochondria, and muscle enzyme levels, improving endurance. Anaerobic changes like increased ATP-PC and glycolytic capacity from sprint or weight training improve strength. Overall, weight training can reduce body fat and increase muscle mass without significantly changing total body weight.
Erik ledin healthy eating
The document discusses how healthy eating helps build muscle. It states that in addition to weight training, one must greatly increase their food intake and eat consistently every day to build muscle bulk and size, particularly for larger individuals. While gaining muscle requires sufficient exercise and calories, increasing calorie intake is necessary for the body to have enough energy to build muscle, even if it means initially gaining weight in the process. The key is balancing calorie intake and exercise to build muscle while adjusting diet as needed to achieve body composition goals.
Getting Ripped Now
To get ripped quickly requires focusing on both diet and exercise. Diet is 70% of the process, requiring a calorie-controlled diet of 2000-2500 calories per day with plenty of lean protein. Exercise must be challenging to exhaust muscles and confuse them through varied, high-intensity interval workouts. Both aerobic and anaerobic exercise are needed, but simply training for endurance will not build significant muscle. Consuming protein shakes can further support muscle growth and recovery.

MERCURY GROUP.BHMS.MATERIA MEDICA.HOMOEOPATHY
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

Muscle Hypertrophy
- 1. Muscle Vocabulary: Hypertrophy By: Kylee J Burt
- 2. What is Muscle Hypertrophy? ● Muscle Hypertrophy is an increase in the size of your skeletal muscles due to the cells it is made up of getting larger.
- 3. Breakdown the Definition... ● In simple terms, muscle hypertrophy is where the muscles that show and make you look stronger get bigger in size.
- 4. How Hypertrophy Happens ● Muscle Hypertrophy has two factors contributing to it; sarcoplasmic hypertrophy and myofibrillar hypertrophy. ● Sarcoplasmic hypertrophy is focused on making your muscle cells be able to store more glycogen. ● Myofibrillar hypertrophy is focused on increasing the size and strength of your muscle attachments and tissues.
- 5. Athletes and Bodybuilders ● Many athletes and mainly bodybuilders use diets,strength training and supplements to help aid in their muscle hypertrophy. ● Since total muscle hypertrophy only happens when both myofibrillar and sarcoplasmic hypertrophy happens,all bodybuilders muscles are unique to them while all are still very large.
- 6. Two different body builders ● Both have very large and strong muscles. ● But,both look slightly different because no two people grow the same.
- 7. THE END
