much as 73% of the oxygen picked up by haemoglobin in the lungs is released in skeletal muscles during periods of physical exercise. Utilisation When we inhale air‚ oxygen is transported to the lungs and can be utilised by the body to stay alive. Oxygen is used to produce ATP for energy “the principle energy transferring molecule in living systems”(Anatomy and Physiology‚ Seeley‚ Stephens‚ Tate). Oxygen is essential to produce ATP. Internal respiration refers to the intracellular metabolic processes

14/03/15 Describe the long-term effects of exercise on the musculoskeletal system and energy systems: Musculoskeletal System: Muscles become bigger and stronger depending on the type of exercise that you do. Such as for strength exercises - heavy weights and low repetitions also increase the strength and size of muscle tissue (which is called muscle hypertrophy). However endurance exercises - low weights and high repetitions which increase the efficiency of the muscle

Christopher Couchell Muscle Physiology Purpose: The Purpose of this exercise is to understand how muscle twitch‚ contract and react to different activities. Exercise 1: Muscle Twitch A. What is a muscle twitch? A muscle twitch is the fasciculation ‚ or "muscle twitch"‚ is a small‚ local‚ involuntary muscle contraction and relaxation visible under the skin. B. According to the graphs‚ which muscle has the fastest twitch? Why? The lateral rectus eye muscle has the fastest twitch.

many differing factors‚ including sex‚ body composition‚ heredity and physical prowess. Introduction: Maximal oxygen consumption (VO₂max) refers to the maximum capacity of an individual body to transport and use oxygen during intense incremental exercise. VO₂max is achieved when the workload continues to increase but the oxygen uptake has halted and achieved a steady state or “plateau”. Achieveing a high VO₂max can be influenced by a multitude of intertwining physiological factors‚ including increased

Benefits of Regular Exercise Carly Smith 11/3/14 C133 Walter In recent years many people have become more and more aware of the need for physical fitness. Almost everywhere people look there is information about improving health. Although the people who are eager to sell vitamins and natural foods commercially drive many of these suggestions‚ some of them‚ especially the information supporting a consistent exercise program‚ deserve attention.

HEALTH BENEFITS OF EXERCISE? Physical exercise is very important for a healthy body. To stay healthy and fit‚ we need to exercise regularly. Most people believe that exercise and work are the same. They believe that if they exert effort‚ flex their muscles during work‚ it is already an exercise. But exercise and work are not the same thing. Although both expend energy‚ exercise has an element of pleasure. When you work‚ you become tired‚ the same as when you exercise. But in exercise‚ there is a sense

of practical life exercises with an explanation about benefits and purpose In the Montessori method‚ demonstration by the teacher is very important to ensure correct and responsible use of the activities. If children are using materials incorrectly or irresponsibly‚ the teacher will again go through a demonstration with the child. The child gain control in the coordination of his movement‚ and help the child to gain independence and adapt to his society. Practical Life Exercises also aid the growth
