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

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
