Anaerobic training intervals should not deplete FTG muscle glycogen stores. During anaerobic training, athletes train to tolerate increased lactic acid accumulations, not to deplete muscle glycogen stores. Aerobic training never depletes STO muscle glycogen or muscle tri-glyceride stores. During aerobic training, athletes improve oxygen transport and decrease the time to muscle tri-glyceride metabolism. During competitions, aerobic athletes maintain blood volumes.
Daily training maintains perfect motor unit contraction and relaxation sequences.
Ballistic activities demand perfect motor unit contraction and relaxation sequence practice every day throughout the year. Ballistic athletes do not benefit from a detraining day. To maintain physiological adaptations requires less daily training stress than to achieve increased physiological adaptations. Maintenance training stress must stimulate physiological systems, but not require physiological adaptations. After training intervals, athletes need recovery intervals.
