Document Summary
Ensure study depicts which type of interval training is used. Metabolic adaptations: enhance the ability of the muscle to produce energy. Morphological adaptations: skeletal muscle composition and fiber type enhances the ability of the muscle to produce power. ^ enzyme activity, muscle glycogen content, buffering capacity. 10 second sprint = breakdown of stored phosphagens (atp, pcr, g6p) 30 second sprint = stored phosphagens > increase in aerobic contribution. Enzymes are - creatine kinase (creatine kinase reaction) - pcr + adp + h = cr + atp. Myokinase (adenylate kinase) - adp + adp = atp + amp. Increase seen with 5sec sprint > 25-55sec rest (short sprints and long rest period) Extended sprints approx 30sec engage short term energy system. Enzymes and glycogen phosphorylase, phosphofructokinase, lactate dehydrogenase. Contribution rises during extended sprints and repeated same sprints. Mitochondrial activation and aerobic adaptations with anaerobic activities. Enzymes are pdh, had< succinate dehydrogenase, citrate synthase (via krebs and etc)
