This document discusses the aerobic and anaerobic energy systems in the body. It explains that muscles need ATP and PCr for energy and contraction. When these run low, the body produces more ATP through anaerobic glycolysis using glycogen or through the aerobic system using carbohydrates and oxygen. The anaerobic system produces lactic acid as a byproduct and is important for short, intense exercise. The aerobic system is more efficient and uses oxygen to break down glucose and fat in the mitochondria. Different types of training can improve anaerobic threshold, aerobic capacity, and other cardiovascular and respiratory adaptations to meet the energy demands of various sports.

Exercise physiology (complete)
(1) Exercise physiology is the study of how the body responds physiologically to acute bouts of exercise and adapts to chronic physical training through temporary responses and more persistent structural changes. (2) Energy for exercise is provided through three main systems - phosphagen, anaerobic, and aerobic - with the relative contribution depending on factors like intensity, time, and an individual's fitness level. (3) Anaerobic glycolysis breaks down carbohydrates into lactate to produce ATP without oxygen and is important for high-intensity exercise, while aerobic metabolism uses oxygen to fully oxidize fuels through pathways like glycolysis, the Krebs cycle, and the electron transport chain.
Principles of Training
The document discusses several principles of training: individual needs, progressive overload, specificity, rest and recovery, and reversibility. It explains that training must match an individual's requirements, sport/position, fitness levels, and goals. Progressive overload means gradually increasing the training demands to gain fitness without injury. Specificity means matching training to the activity. Rest and recovery are needed to repair damage from training. The FITT principle refers to frequency, intensity, time, and type of training as ways to progressively overload the body. Reversibility means fitness levels will decline if training is stopped.

Energy system
Energy is stored in the body primarily as ATP and creatine phosphate and is replenished through three main energy systems - the phosphagen, glycolytic, and aerobic systems. The phosphagen system uses ATP and creatine phosphate to rapidly produce energy for intense bursts of activity under 10 seconds. Between 10-30 seconds, the glycolytic system takes over using glycogen to produce lactate and energy. For sustained activity over 30 seconds, the aerobic system kicks in, using oxygen to fully oxidize carbohydrates, fats, and proteins to carbon dioxide and water to efficiently generate energy through pathways like glycolysis, the Krebs cycle, and the electron transport chain.
Exercise physiology
Exercise physiology is concerned with the study of how the body adapts physiologically to the acute stress of exercise or physical activity, and the chronic stress of physical training.
Muscle Energy Systems
Muscle metabolism relies on ATP as the direct source of energy for contraction. ATP stores are quickly depleted after 4-6 seconds of contraction and must be regenerated through creatine phosphate interaction, anaerobic glycolysis, and aerobic respiration. When muscle activity reaches 70% of maximum, oxygen delivery is impaired and lactic acid builds up, diffusing into the bloodstream. Muscle fatigue occurs when ATP production cannot keep up with demand, leading to relative ATP deficit, contractures, and lactic acid accumulation.
Aerobic and anaerobic exercise
The document discusses the differences between aerobic and anaerobic exercise and respiration. Aerobic respiration uses oxygen to produce energy through a slower process, while anaerobic respiration produces energy faster without oxygen. Aerobic exercise relies on the aerobic system and includes moderate to hard continuous activities like long-distance running. Anaerobic exercise is very short and intense, like sprints, using fast bursts that outpace the body's oxygen delivery. The recovery period after anaerobic exercise allows the body to pay back its oxygen debt from lactic acid buildup.
Sports Performance
This document defines and compares physical activity, play, and sport. It also discusses health versus physical fitness, with health relating to total well-being and fitness relating to physical attributes. The document then discusses the three energy systems the body uses - ATP-PC system for short bursts, lactic acid system for durations up to a few minutes, and aerobic system for longer durations. It provides details on how each system works, including the breakdown of fuels like carbohydrates and production of ATP.

Ergogenic aids for exercise and sports performance
This document discusses various ergogenic aids (performance-enhancing substances), including anabolic steroids, human growth hormone, and erythropoietin. It describes the physiological effects of each substance, such as increased muscle growth, strength, and red blood cell count. It also identifies sports that may benefit from these effects, like sprinting, bodybuilding, and endurance sports. However, the document warns that long-term use of these banned substances can have serious health implications, including organ damage, cardiovascular disease, blood clots, and stroke.
Strength training
This document discusses key concepts related to adaptations to resistance training. It defines muscular strength, power, and endurance. It describes measurements of one-repetition maximum and covers topics like muscle hypertrophy, fiber size increases, effects of inactivity, muscle soreness, and resistance training program design. It emphasizes that resistance training can improve strength by 25-100% within 3-6 months and benefit all populations.
Flexibility
Flexibility refers to the range of motion in joints. There are several types of flexibility including dynamic, static active, and static passive flexibility. Flexibility is important for physical fitness and injury prevention. When stretching, one should warm up first, hold stretches for 30 seconds, and avoid ballistic stretching which can cause injury. Proper flexibility training involves techniques such as static, dynamic, isometric, PNF, and ballistic stretching.
Introduction to exercise physiology
The document provides an introduction to exercise physiology, defining key terms like physical activity, exercise, and physical fitness. It discusses the acute and chronic adaptations to exercise training and how exercise physiology principles can be applied to fields like cardiology, endocrinology, and physical therapy. The summary also outlines the history of exercise physiology laboratories and professional organizations in the field.
Energy systems main lesson
The document discusses how the body produces energy through different energy systems using carbohydrates, fats, and proteins. There are three main energy systems: 1) the phosphocreatine system which produces ATP very rapidly but has limited capacity, 2) the lactic acid system which produces ATP rapidly but leads to lactic acid buildup and fatigue, and 3) the aerobic system which produces ATP slowly through oxygen but has unlimited capacity. The type of energy system used depends on the intensity and duration of exercise.
Energy systems
This document discusses the three energy systems - ATP-PC, anaerobic glycolysis, and aerobic - that produce ATP to enable muscle contractions. The ATP-PC and anaerobic glycolysis systems produce ATP quickly but in small amounts and can only be used for short durations before causing muscle fatigue. The aerobic system produces large amounts of ATP over long durations without causing fatigue but takes longer to produce ATP. The energy system used depends on the activity duration, intensity, fitness level, and recovery time between efforts.
Anaerobic exercise
Anaerobic exercise relies on glycogen stores and produces lactic acid as a byproduct. It is short and intense activity that builds muscle strength without using oxygen. Examples include sprinting, weightlifting, circuit training, calisthenics, and many sports. Benefits include increased muscle and bone strength, a higher metabolism, and fat replacement by muscle. Risks involve high blood pressure during exercise and lactic acid buildup. Proper warmups, cool downs, nutrition, and checking with a doctor are recommended before starting an anaerobic exercise routine.
Chronic adaptations
This is an assignment on chronic adaptations due to training for my PE unit at uni. There are a couple of classroom activities included also!
Energy expenditure during jogging & running
This document discusses factors that influence the energy expenditure of jogging and running. It covers topics such as the difference between jogging and running in terms of speed and aerobic demands. It also discusses how running economy, stride length, air resistance, and other factors can impact the caloric cost and oxygen uptake of running at different speeds. The optimum combination of stride length and frequency depends on the individual and their running style. Overcoming air resistance accounts for 3-9% of the total energy requirement of running.
Aerobic and anaerobic training
Aerobic means "with oxygen," and anaerobic means "without oxygen." Anaerobic exercise is the type where you get out of breath in just a few moments, like when you lift weights for improving strength, when you sprint, or when you climb a long flight of stairs.
Principles of Training
The document discusses several principles of exercise and strength training, including specificity, overload, progression, and reversibility. It provides examples and studies to illustrate each principle. Specificity refers to the body adapting specifically to the demands placed on it during exercise. The overload principle notes that the body only adapts when under greater stress than usual. Progression means building up training in a step-wise manner. Reversibility means adaptations are lost if training stops or decreases.
Human Energy Transfer During Exercise
The document discusses human energy transfer during exercise and rest. It explains that exercise is a stressor that disrupts homeostasis and causes oxygen consumption to rise slowly over 1-4 minutes, creating an oxygen deficit that relies on anaerobic metabolism. This oxygen deficit ends when steady-state aerobic metabolism is reached. After exercise, excess post-exercise oxygen consumption (EPOC) occurs as oxygen consumption remains elevated for minutes to days to restore homeostasis. The document reviews evidence that higher intensity exercise, shorter rest periods between sets, and more frequent daily exercise sessions result in greater EPOC and could impact body composition through increased calorie expenditure.
Principles of Training
This document outlines several key principles of training:
1) Warm ups and cool downs are important to reduce injury risk and muscle soreness. Warm ups should include light exercise and stretching while cool downs involve decreasing intensity over time.
2) The overload principle states that exercise must gradually increase in frequency, intensity, or duration to continue providing training benefits. Too much overload can lead to injury.
3) Training must be specific to the demands of the sport through targeting relevant muscle groups, energy systems, skills and fitness components. Variety is also important to avoid boredom.
Physiological effects of aerobic exercises
Cardio and muscle endurance
Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. Aerobic literally means "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism. Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time
principle of aerobic exercise physiology
The document discusses the principles of aerobic and anaerobic exercise. It defines aerobic exercise as exercise that can be performed for a long period of time without becoming breathless, while anaerobic exercise involves high intensity activity for short bursts. The goals of aerobic training include improving endurance, cardiovascular fitness and muscular strength in major muscle groups like calves, quadriceps, hamstrings and gluteals. Anaerobic training aims to improve strength, muscle size, power, and anaerobic metabolism. The document also outlines some of the physiological adaptations that occur with each type of training.

Strength training
Strength is the ability to overcome resistance through muscle contractions and depends on the energy liberation process in muscles. There are different types of strength abilities important for sports. Maximum strength is the ability to generate maximum force against resistance. Explosive strength combines strength and speed to overcome resistance quickly. Strength endurance is the ability to exert force against resistance while fatigued. The type of strength required depends on the specific demands of the sport.
Role of anaerobic and anaerobic metabolism in exercise.
Exercise enhances physical fitness and health through strengthening muscles and cardiovascular system. There are two main types of metabolism during exercise - aerobic and anaerobic. Aerobic exercise uses oxygen to breakdown fuels slowly for sustained activity like running and swimming. Anaerobic exercise relies on fast glycolysis, producing lactic acid for high intensity activities under 2 minutes. Both have benefits like reduced disease risk but different muscle adaptations for endurance versus strength/power.

DETRAINING IN RELATION TO SKELETAL MUSCLE
Detraining occurs when there is a reduction or cessation of training, leading to partial or complete loss of physiological and performance adaptations. Periods of detraining are common for athletes during injuries or holidays. Muscle atrophy is characterized by a decrease in muscle mass and occurs due to inhibition of protein synthesis during inactivity. The degree of atrophy depends on the length of inactivity. While short detraining periods under 2 weeks may not affect muscle fibers, longer periods can decrease fiber size, especially in fast-twitch fibers. Maintaining some exercise during injury can help limit muscle atrophy.
Sports Nutrition Tilly Hunt
This document provides guidance on sports nutrition, including what to eat before and after exercise. It recommends eating carbohydrate-rich foods 3-4 hours before exercise for digestion and foods like sports drinks 1 hour before. After exercise, it recommends consuming carbohydrates within 1 hour to replenish glycogen stores and aiming to replace 125-150% of fluid lost through sweating in the 4-6 hours after to rehydrate. While supplements can help meet goals, a diet of real foods is generally best for recovery.

Exercise for impaired balance by DR. H.Bilal Malakandi, PT
Introduction to Balance and its concepts, Impaired balance and then management of impaired balance.
Based on Therapeutic Exercise Foundations and Techniques
Exercise physiology
The ventilatory and cardiovascular systems work together to increase oxygen delivery during exercise in order to maintain homeostasis. The ventilatory system increases breathing rate and volume through actions of the diaphragm and intercostal muscles. The cardiovascular system increases cardiac output through higher heart rate and stroke volume to distribute more blood to working muscles. Both systems must precisely coordinate their responses to exercise in order to meet increased demand for oxygen while removing carbon dioxide.
Exercise physiology 5
This document discusses various methods for measuring energy expenditure and oxygen consumption, including direct and indirect calorimetry. Direct calorimetry measures heat production directly, but is expensive and impractical. Indirect calorimetry estimates energy expenditure by measuring oxygen consumption and carbon dioxide production, and can be done via closed or open circuit spirometry. Maximal oxygen uptake (VO2max) represents the maximum rate of oxygen consumption during exercise and is a measure of aerobic capacity.
Aerobic exercise and Anaerobic exercise
Aerobic exercise involves physical activity that increases oxygen supply to the muscles and can be sustained for a period without rest. It helps improve cardiovascular health and lower resting heart rate. Examples include walking and jogging. Anaerobic exercise increases speed and muscle strength but cannot be sustained for more than a few minutes before needing rest. It focuses more on strength than cardiovascular health. Examples are sprinting. The document also provides tips for avoiding injuries like listening to your body and dressing appropriately for weather conditions.
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
High intensity interval training
This document discusses high-intensity interval training (HIIT) and its benefits compared to endurance training. HIIT involves short bursts of intense exercise alternated with recovery periods. A typical HIIT session involves sprinting for 30 seconds followed by a 1 minute recovery period, repeated 4-6 times. Studies have shown that HIIT can improve aerobic capacity, fat metabolism, and endurance as much as longer endurance training, but with less time commitment - around 15 minutes for HIIT versus hours for endurance training. The intensity of HIIT places more stress on the body than endurance training, leading to more rapid adaptations in factors like mitochondria and fat burning.
Anaerobic-Aerobic Treatment of Sewage
The document proposes an anaerobic-aerobic process for treating domestic sewage using LEVAPOR biofilm technology. The process involves pre-treating sewage under anaerobic conditions in a biofilm reactor to reduce energy use and excess sludge production compared to conventional aerobic treatment. Sewage would then undergo post-treatment under aerobic conditions to further reduce pollutants before discharge. This process could achieve up to 75% lower energy use and 67% less sludge than aerobic treatment alone, while also producing biogas as an energy source.
Children Exercise Physiology
The document discusses children's exercise physiology. It notes that children are not smaller versions of adults, as they have important physiological differences related to growth and maturation. Their aerobic capacity peaks at a younger age compared to adults and their anaerobic power is significantly lower. The document also addresses nutritional considerations, psychological factors, injuries risks and how to prevent injuries in child athletes.
what is interval training?
In this short presentation you will learn about what interval training is and how you can benefit from it.
Energy systems 2
The document summarizes the different energy systems the human body uses to produce energy for physical activity. It discusses the ATP-CP, anaerobic glycolysis, and aerobic energy systems. The ATP-CP system provides energy for bursts of intense activity lasting 2-3 seconds. The anaerobic glycolysis system lasts 2-3 minutes and produces energy without oxygen. The aerobic system provides sustained energy for longer duration activities lasting several minutes by using oxygen to break down carbohydrates and fat.
Interval training
El interval training o entrenamiento interválico consiste en alternar períodos cortos de esfuerzo intenso con descansos. Fue desarrollado en los años 40-50 y popularizado por el corredor Emil Zatopek. Ofrece beneficios como mejorar la resistencia, coordinación y capacidad aeróbica y respiratoria, además de ayudar a quemar calorías. Se recomienda precaución al realizarlo para prevenir lesiones.
Energy system table
The document summarizes three energy systems:
1) ATP-PC system uses phosphocreatine to produce energy instantly for intense bursts up to 10 seconds.
2) Lactic acid system uses glycogen to produce fast energy for activities lasting 10-75 seconds through anaerobic glycolysis.
3) Aerobic system uses oxygen and fuels like carbohydrates and fats to produce sustained energy over 75 seconds through aerobic glycolysis.
Muscle fibre types and contractions
This document discusses muscle fiber types and muscle contractions. It notes that there are two main types of muscle fibers - slow-twitch and fast-twitch fibers - which are suited to different physical activities based on intensity. It also outlines the three types of muscle contractions: isotonic contractions where the muscle shortens or lengthens, and isometric contractions where the muscle contracts without movement.
Immunity
The document discusses immunity and the immune system. It describes the three lines of defense against microorganisms as intact skin/mucus membranes, the innate immune system, and the acquired immune system. The acquired system has both cell-mediated and antibody-mediated immunity. Key cells involved include T cells, B cells, macrophages, neutrophils, and natural killer cells. The adaptive response has memory and specificity. Both innate and adaptive immunity provide protection through cells and proteins like antibodies and cytokines.
Energy
The document discusses different methods to measure energy expenditure in the human body. Indirect calorimetry measures oxygen consumption to estimate energy expenditure, using a spirometer to measure air volume and composition. Heart rate monitoring relates heart rate increases to increased oxygen consumption and energy expenditure based on an individual's established relationship. While direct calorimetry directly measures heat production for most accurate results, indirect methods and heart rate monitoring provide reasonably accurate alternatives in a cheaper and easier manner.
Energy Expenditure
This document discusses methods for estimating total daily energy expenditure (TDEE). TDEE can be estimated by calculating basal metabolic rate (BMR) using tables or equations, adjusting for daily activity level, and adding the estimated energy cost of exercise. The document provides tables and examples to guide estimating BMR, selecting an activity level factor, and calculating weekly and daily exercise energy expenditure to determine overall TDEE. Accurately estimating TDEE and balancing energy intake can help manage body weight over the long term.
Effect Of Training On The Anaerobic Energy System
The document discusses the anaerobic energy system and how it can be improved through training. It describes the ATP-PC system which provides energy for up to 10 seconds and the lactic acid system which provides energy for 30-60 seconds. Methods of anaerobic training include interval training, resistance training, sprinting and weightlifting. Physiological adaptations to anaerobic training include increased muscle strength, larger ATP and PC stores, improved power output, and development of fast-twitch muscle fibers. Adaptations depend on the type of training and the individual athlete.
Interval training
El interval training consiste en alternar periodos de alta intensidad con periodos de descanso activo. Mejora notablemente la resistencia física, la capacidad aeróbica y la quema de calorías. Existen diferentes tipos como realizar series de 300 metros a intensidad moderada con descansos de 3 minutos, o hacer 12 diagonales a alta intensidad con descansos trotando.
Muscular fatigue mechanisms 2011
1. The document discusses various mechanisms of muscular fatigue, including fuel depletion, accumulation of metabolic by-products like lactic acid, and elevated body temperature.
2. It explains how different types of exercise and energy systems used can lead to different types and onset of fatigue. High intensity anaerobic exercise can cause faster fatigue due to reliance on anaerobic pathways.
3. Recovery is important to reverse fatigue and prepare for future exercise. Different recovery strategies should be used depending on the predominant energy system and causes of fatigue.

Sources of energy dr gad
This document discusses sources of energy during rest and exercise. It explains that cells use ATP as their main source of energy, which is produced through breaking down nutrients like carbohydrates, fats, and proteins. There are three main energy systems: phosphagen, anaerobic glycolysis, and aerobic. Phosphagen provides immediate energy for bursts of activity up to 10 seconds. Anaerobic glycolysis fuels moderate intensity exercise up to 2 minutes through lactate production. Aerobic oxidation sustains long duration activities by producing large amounts of ATP from oxygen. Recovery from exercise involves paying back oxygen debt and replenishing energy stores through lactate clearance and glycogen resynthesis.
AerobicandAnaerobic MuscleMetabolism (1).ppt
ATP is the energy currency used by muscles, which obtain energy through aerobic and anaerobic metabolism in their mitochondria and glycogen stores. Fast-twitch white muscle fibers rely more on anaerobic glycolysis while slow-twitch red fibers use aerobic metabolism. During exercise, muscles sequentially use ATP, phosphocreatine, and glycogen stores, and shuttle waste products like lactate and alanine to the liver via Cori and glucose-alanine cycles to regenerate ATP.
L3-RS_Aerobic & Anaerobic Metabolism in Muscles_MSK_Block_Dec2013.ppt
This document discusses energy metabolism in skeletal muscles. It begins by explaining that ATP is the main energy source for muscles and is produced through three systems: phosphocreatine, aerobic metabolism, and anaerobic metabolism. There are two main types of muscle fibers: slow-twitch fibers that rely on aerobic metabolism and are fatigue-resistant, and fast-twitch fibers that rely on anaerobic glycolysis and fatigue more easily. During exercise, muscles initially use stored ATP and phosphocreatine, and then anaerobic glycolysis produces lactate as a byproduct. Aerobic metabolism kicks in after oxygen delivery increases. The document also describes the Cori cycle and glucose-alanine cycle which help shuttle lact

Lesson 11[1 St Dec 2008]
The human body uses three main energy systems - the ATP-PCr system, anaerobic glycolysis, and oxidative phosphorylation - to produce energy for muscle contraction. The ATP-PCr system provides energy for intense bursts of activity lasting up to 10 seconds. Anaerobic glycolysis is used for activities lasting 20 seconds to 2 minutes and produces lactic acid as a byproduct. Oxidative phosphorylation provides virtually unlimited energy through aerobic metabolism for endurance activities lasting several minutes or more.
Introduction to the energy systems

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.
aerobic and anaerobic.pptx
The document discusses aerobic and anaerobic energy pathways and the three energy systems - ATP-PC, lactic acid, and aerobic.
It defines aerobic and anaerobic exercise and explains that aerobic exercise relies on oxygen to produce energy through the aerobic system, while anaerobic exercise uses the ATP-PC and lactic acid systems without oxygen.
The three systems work together to produce ATP but their relative contributions depend on the intensity and duration of exercise, with the ATP-PC system providing rapid energy for up to 10 seconds, the lactic acid system taking over for 2-3 minutes, and the aerobic system becoming dominant for prolonged submaximal exercise.
Energy systems assignment
Phosphocreatine allows for rapid production of ATP, boosting performance in high-intensity short-duration activities like sprints and weight training. It exists in limited stores in the body and is replenished through diet and endogenous production. The lactic acid energy system produces ATP anaerobically for up to 90 seconds of maximal work, but lactic acid buildup leads to fatigue. The aerobic system produces ATP slowly through 3 stages, but can sustain low-to-moderate intensity exercise indefinitely due to virtually limitless capacity. The intensity and duration of exercise determines which energy systems are utilized.
