Basics of exercise physiology
Exercise Physiology: Theory and application to Running.
Exercise physiology, a highly dynamic and deep topic, is critical to understand in order to optimise physical performance.
Robert Henning (B.Sc, B.ScHons, M.Sc) from Pacer Running discusses research and application on the topic.
Chap 84
1. Exercise increases energy expenditure through increased fuel consumption and oxygen usage, reflected by higher oxygen consumption and carbon dioxide production.
2. Increased oxygen delivery and carbon dioxide removal in tissues during exercise is achieved through cardiovascular and respiratory responses.
3. Types of exercise include static, which involves constant muscle tension, and dynamic, which involves rhythmic contraction and relaxation with changing muscle length. Aerobic exercise uses oxygen and fuels stored in muscles, while anaerobic exercise occurs without oxygen, using stored creatine phosphate and glycogen.
Shower Benefits For Athlete
While warm showers can soothe sore muscles after exercise, very hot water damages the skin. Studies show that hot showers, along with cold dry air and excessive scrubbing, can lead to dry skin. Taking a shower immediately after a workout is not recommended as it lessens muscle inflammation and pain caused by intense exercise. Both hot and cold showers provide benefits - hot showers relax muscles and increase blood flow while cold showers increase blood circulation and boost immune system and mental strength. Steam showers similarly improve blood flow and flexibility.
Components of fitness
There are 5 components of fitness: cardio-respiratory endurance improves heart and lung health through aerobic exercise; flexibility enhances range of motion and reduces injury risk; muscular strength builds new muscle through high power, short burst activities; muscular endurance uses muscles over long periods through activities like hiking; and body composition refers to the ratio of fat to muscle which impacts health risks when fat levels are excessive.
Exercise physiology
This document discusses exercise physiology and the effects of exercise on the body. It covers the following key points:
1. It describes different types of exercises like aerobics, yoga, and resistance training and discusses how muscles are characterized by strength, power, and endurance.
2. It explains how acute and chronic exercise affects the cardiovascular, respiratory, and muscular metabolic systems like increasing oxygen consumption and improving lung capacity.
3. It discusses the risks of overheating during exercise and how the body regulates fluids and electrolytes to prevent issues like dehydration, cramps and nausea. Regular exercise provides benefits such as regulating blood pressure and sugar levels.
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.

Responses to exercise
The document summarizes the acute and chronic responses of the body to exercise. For acute responses, it describes how cardiovascular factors like heart rate, stroke volume, and blood pressure increase during exercise to deliver more oxygen to working muscles. Respiratory responses also increase oxygen uptake and ventilation. Chronic adaptations to training include increased maximum oxygen uptake and efficiency of oxygen delivery systems in the cardiovascular and respiratory systems over 6-8 weeks of regular aerobic training. Anaerobic training leads to increased muscle size, strength and power over the same duration.

Recovery and fatigue
This document discusses recovery and fatigue in athletes. It describes different types of fatigue including muscular fatigue caused by fuel depletion and buildup of metabolic byproducts. It also discusses how increased body temperature and dehydration can lead to fatigue. Recovery processes are outlined including active recovery, rest, replenishing energy stores, rehydration, and various therapies like hydrotherapy, cryotherapy, massage and specialists who can aid recovery. Ethical considerations in sport medicine are also mentioned.
Immediate effects-of-exercise
Regular exercise provides both immediate and long-term benefits to the body. In the short-term, the body experiences increased heart rate and breathing to supply oxygen to working muscles, elevated body temperature through the generation of heat, sweating to regulate temperature, and muscle fatigue from lactic acid buildup. Over time with training, the cardiovascular system becomes more efficient as the heart can deliver the same blood volume with fewer beats, the recovery rate is quicker, and the resting heart rate is lower.
1.2.2 Lesson 2 - physiological effects
The cardiovascular system consists of the heart, blood vessels, and blood. When exercising, the immediate effects are an increased heart rate and blood pressure, faster and deeper breathing, increased body temperature through muscle heat production, and sweating to cool down. Regular exercise leads to long-term benefits like a stronger, more efficient heart with a lower resting heart rate, increased cardiac output and stroke volume, improved recovery rate, and decreased blood pressure.
Lesson2
This document discusses key concepts related to the blood transportation system during exercise. It covers how blood flow is distributed differently during exercise compared to rest, with increased blood flow to skeletal muscles achieved through vascular shunting. It also summarizes the venous return mechanism and its importance in getting blood back to the heart, highlighting the roles of valves, the skeletal muscle pump, and respiratory pump. Finally, it examines the arteriovenous oxygen difference (a-VO2 difference) and how it increases during exercise to enhance oxygen diffusion to working muscles.
Physiological changes during sports and exercise
During exercise and sports, the body undergoes several physiological changes. Moderate exercise increases cardiac output to 20 liters per minute as the heart rate and breathing rate increase. Severe exercise can increase cardiac output to 35 liters per minute. The lungs work harder to remove more carbon dioxide. The blood experiences mild hypoxia which increases red blood cell production. Muscles produce more lactic acid as an end product of metabolism. The skin, kidneys, lungs, and gastrointestinal system all work to eliminate and process wastes from the increased activity levels in the body during exercise.
Long term effect of exercise - Cardiovascular and energy systems.ppt
Regular exercise leads to adaptations in the body's cardiovascular and energy systems. The cardiovascular system strengthens through increases in stroke volume, cardiac output, and capillarization. It also becomes more efficient, with lower resting heart rate, blood pressure, and faster recovery. The energy systems adapt through increased enzymes for aerobic and anaerobic metabolism, larger mitochondria, and greater fat burning ability. A 6-week training program could examine changes in heart rate, blood pressure, and aerobic fitness to record cardiovascular improvements.
S&W Black House
The document discusses warm-ups, which are physical activities done before exercise to gradually increase body temperature and prepare the body. A proper warm-up prepares the body mentally and physically, improves training effectiveness, and decreases injury risk. The effects of warming up include increased heart rate and blood flow, raised muscle temperature, enhanced nerve conduction, and elevated muscle metabolism. The document also describes types of stretches like ballistic, static, and contraindicative stretches.
fatigue and recovery
Fatigue during exercise is caused by multiple factors including fuel depletion, accumulation of metabolic by-products, and neuromuscular events. Specifically, fatigue results from the depletion of ATP and phosphocreatine stores as well as glycogen. The buildup of lactic acid and other products like inorganic phosphate and ADP also contribute to muscle fatigue by interfering with muscle contraction. Elevated body temperature from exercise can further increase fatigue. Recovery methods aim to replenish energy stores and remove waste products through rest, active recovery, hydrotherapies, massage, and other techniques.
Lesson 2 long term effects of exercise
The document discusses the impact of a healthy, active lifestyle on the cardiovascular system. It states that regular exercise leads to long-term benefits like an enlarged and thicker heart muscle, lower resting heart rate, increased stroke volume and cardiac output, improved recovery rate, and healthier veins and arteries. It also notes that a healthy diet low in saturated fats and cholesterol helps lower blood pressure and improves cholesterol levels. Maintaining an active lifestyle with exercise and a nutritious diet promotes cardiovascular health.

Sport unit 2 p4
Regular exercise leads to several long-term effects on the cardiovascular and respiratory systems. The heart muscle thickens and increases in size, raising stroke volume and cardiac output. This allows the heart to pump more blood with each beat and a lower resting heart rate. Capilliarization improves oxygen delivery to working muscles. Blood volume and aerobic fitness increase while resting blood pressure and recovery time decrease. The muscular system also adapts through increased myoglobin and mitochondria stores, glycogen and fat storage, tendon and muscle strength, and tolerance to lactic acid buildup.
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.
Basic Exercise physiology
This document provides an overview of basic exercise physiology, covering the cardiovascular, respiratory, neuromuscular, and endocrine systems as well as energy systems. It describes the structure and function of each system at rest and in response to exercise. The cardiovascular system increases cardiac output to meet oxygen demands during exercise. The respiratory system increases ventilation to supply more oxygen to working muscles. The neuromuscular system controls voluntary movement through motor neurons. Hormones released by the endocrine system prepare and regulate the body's response to exercise. There are three energy systems - phosphogen, anaerobic and aerobic - that provide ATP for muscle contraction depending on exercise intensity and duration.
1.2.2 Lesson 1 - immediate effects on the cv system
The cardiovascular system consists of the heart, blood vessels, and blood. The heart pumps blood through three types of blood vessels - arteries, veins, and capillaries. Exercise has immediate effects on the cardiovascular system such as increased heart rate and blood pressure. The heart contains four chambers and blood pressure can be measured to track systolic and diastolic pressure. Maintaining a healthy cardiovascular system requires regular exercise and avoiding unhealthy behaviors.
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.
Pdhpe prereading physiological adaptations
Aerobic training causes six main physiological adaptations that improve athletic performance: 1) resting heart rate decreases as the heart becomes more efficient, 2) stroke volume and cardiac output increase allowing the heart to pump more blood per beat to deliver more oxygen to working muscles, 3) oxygen uptake increases through improved cardiovascular and respiratory efficiency while lung capacity remains unchanged, 4) haemoglobin levels rise to transport more oxygen in the bloodstream, 5) muscle hypertrophy occurs through increased muscle fiber size from resistance training, and 6) aerobic training enlarges slow-twitch muscle fibers more than fast-twitch fibers.
Chapter 3 presentation slides edex
This document discusses the effects of exercise on various body systems. It outlines how aerobic endurance training leads to increased muscle fiber size, vascularization, energy stores, and force exertion. It also describes adaptations like increased mitochondria, lactate tolerance, and fat metabolism efficiency. Additionally, it notes that exercise results in increased red blood cell volume and lower blood viscosity to enhance oxygen transport. Finally, it compares breathing during exercise versus rest, noting exercise involves deeper, faster breathing using primary muscles while expiration is more active.
Effects of Exercise on Cardiovascular System
Regular exercise has both short-term and long-term benefits for the cardiovascular system. It increases stroke volume and lowers resting heart rate, making the heart stronger and more efficient. Exercise also lowers blood pressure and improves blood flow, directing more blood to skeletal muscles. Long-term, it enhances blood vessel lining and lowers the risk of plaque buildup. The first part of the body to benefit from regular exercise is the heart.
Effects on cardiovascular system
Regular exercise has long-term benefits for the cardiovascular system. It decreases resting heart rate and improves heart recovery rate as the heart becomes stronger and more efficient. Additional benefits include increased stroke volume, meaning the heart can pump more blood with each beat, as well as reduced blood pressure. Overall, regular exercise leads to a more efficient cardiovascular system that is under less stress.

Discover the Simplified Electron and Muon Model: A New Wave-Based Approach to Understanding Particles delves into a groundbreaking theory that presents electrons and muons as rotating soliton waves within oscillating spacetime. Geared towards students, researchers, and science buffs, this book breaks down complex ideas into simple explanations. It covers topics such as electron waves, temporal dynamics, and the implications of this model on particle physics. With clear illustrations and easy-to-follow explanations, readers will gain a new outlook on the universe's fundamental nature.
A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
