Sample Answer
- The ATP-PCr system activates instantly for explosive combinations and power punches. It provides maximum force for 10-15 seconds before depletion occurs.
- Sustained exchanges beyond 10 seconds shift dominance to the glycolytic system. This maintains high-intensity output for combinations lasting up to 60 seconds.
- The aerobic system operates continuously throughout the round at varying intensities. It provides baseline energy during footwork and defensive movements.
- All three systems function simultaneously rather than sequentially during combat. Their relative contributions fluctuate based on fighting intensity and duration.
- Brief pauses between exchanges allow partial PCr replenishment within 20-30 seconds. This enables repeated explosive efforts throughout the round.
- Lactic acid progressively accumulates from repeated high-intensity combinations. This causes fatigue and reduced punching power in the round’s final minute.
- Skilled boxers manage intensity fluctuations to optimise energy system contributions. They alternate between explosive attacks and active recovery movements.
