For Training Thresholds
- [P] Training thresholds provide effective guidelines for targeting specific energy system adaptations in endurance athletes.
- [E] Working within aerobic threshold zones enables systematic development of cardiovascular efficiency and fat oxidation capacity.
- [Ev] Research demonstrates that training at 60-85% maximum heart rate optimises mitochondrial adaptations and capillary density improvements.
- [L] Therefore threshold-based training effectively develops the aerobic base essential for endurance performance.
Against Single Threshold Approaches
- [P] Relying exclusively on predetermined thresholds limits comprehensive energy system development in competitive athletes.
- [E] Individual physiological responses vary significantly, making standardised threshold percentages potentially inappropriate for some athletes.
- [Ev] Studies show lactate and anaerobic thresholds occur at different intensities between individuals despite similar fitness levels.
- [L] Consequently maintaining rigid thresholds may prevent optimal training adaptations in certain athletes.
Balanced Approach
- [P] Combining threshold guidelines with individualised monitoring provides the most effective energy system development strategy.
- [E] This approach allows coaches to adjust training intensities based on physiological responses rather than predetermined percentages.
- [Ev] Evidence indicates personalised threshold training produces superior VO2 max and lactate clearance improvements.
- [L] Therefore adaptable threshold use optimises energy system adaptations for diverse endurance athletes.
