Energy continuum of physical activity

Duration of maximal effort: 3+ mins - Energy supplied by: Aerobic Example: marathon, cross country skiing Duration of maximal effort: 8-90 seconds - Energy supplied by: ATP-PC and anaerobic glycolytic Example: 200m, 400m, gymnastic floor routine Duration of maximal effort: 10 seconds - Energy supplied by: ATP-PC Example: 100m, long jump Duration of maximal effort: 90secs to 3mins - Energy supplied by: anaerobic glycolytic and aerobic Example: 1500m, a round of boxing Energy continuum - A term which describes the type of respiration used by physical activities. Whether it is aerobic or anaerobic respiration depends on the intensity and duration of the exercise Explaining the continuum - Explained in terms of threshold ATP-PC/anaerobic glycolytic threshold is the point at which the atp-pc system is exhausted by intensity of exercise so anaerobic glycolytic system takes over Fast Twitch (Type IIx) ATP - Main pat
