Sample Answer
- Short duration sprints (0-10s) develop ATP-PCr system for explosive movements like beating defenders, improving both immediate energy availability and phosphocreatine regeneration.
- Medium duration high-intensity activities (30-90s) enhance the glycolytic system through attacking play sequences, increasing players’ lactate threshold and repeated sprint ability.
- Longer duration aerobic training improves base fitness and oxygen utilisation through small-sided games, enabling sustained performance across 90 minutes and enhanced recovery capacity.
- Recovery periods between activities must match energy system demands (3 minutes for ATP-PCr, 5 minutes for lactate clearance) to optimise training adaptations.
- Training must integrate varied durations to develop all energy systems simultaneously, meeting soccer’s specific demands from explosive sprints to sustained moderate activity.
