Detailed explanation-1: -ATP-PC System This energy system is for immediate activity for activities of short duration (lasting 0-10 seconds), high intensity & explosive activities, such as the 100m sprint, therefore fast twitch muscle fibres are recruited.
Detailed explanation-2: -Lactic acid is formed and accumulated in the muscle under conditions of high energy demand, rapid fluctuations of the energy requirement and insufficient supply of O2. During intense exercise sustained to fatigue muscle pH decreases to about 6.4-6.6.
Detailed explanation-3: -The system does not use oxygen, but rather your body’s CP (creatine phosphate) stores to create energy for a short duration. Shot-putters, weight lifters, football players, gymnasts, sprint-distance runners, or any athlete that utilizes explosive movements will utilize this energy system.
