Energy System Interplay
All 3 energy systems contribute to ATP synthesis, from 0-10 seconds of the event, ATP-PC is the dominant energy system while anaerobic glycolysis and aerobic glycolysis is increasing its contributions.. After 10 seconds, ATP-PC is decreasin its contribution while aerobic glycolysis is increasing its contribution and the dominant energy system is anaerobic glycolysis. If the event lasts longer than 1 minute, aerobic glycolysis will be become the dominant energy system while anaerobic decrease its contribution.
Likely cause of fatigue
Likely cause of fatigue would be the metabolic by products
