Sample Answer
- During explosive movements like jumping and sprinting, the ATP-PCr system predominates due to immediate energy demands lasting 2-10 seconds.
- Fast breaks and sustained defensive pressure rely on the glycolytic system for high-intensity efforts lasting 30-90 seconds.
- During timeouts and low-intensity periods, the aerobic system becomes predominant, facilitating recovery and ATP-PCr replenishment.
- Game intensity, player fitness level, and tactical demands influence which system dominates at any given moment.
- Quarter breaks allow complete energy system recovery, resetting metabolic demands for subsequent periods.
