Document Summary

Determines how much time people spend at different intensities required for that particular sport. How strong they have to be: to meet the demands for that particular sport. Amount of recovery time in the sport dictates the possible intensities that people can perform at: more time between efforts = greater ability to perform at high level from a power output perspective (work to rest ratio) For most sports, there"s a combination of aerobic and anaerobic capacities. Most of this capacity comes from training and practice. Aerobic metabolism: increase capacity volume, duration and intensity, increase fuel storage, sparing of cho fatigue if delete glycogen stores. Increased in mitochondrial size and number = get more enzyme activity. This results in an increased aerobic capacity. Duration and intensity of exercise are also important influences on these adaptations. Gastrocnemius enzyme activity in untrained (ut), moderately trained (mt) joggers and highly trained (ht) marathon runners.
