Sample Answer
- HIIT increases ATP-PCr stores and phosphocreatine enzyme activity within muscle cells, enhancing the capacity for immediate energy production during explosive movements and repeated short-duration efforts.
- Training at lactate threshold intensity improves the body’s lactate buffering capacity and tolerance to lactic acid accumulation, enabling athletes to maintain higher intensities for longer periods when relying on glycolytic system energy production.
- Aerobic training at moderate intensities increases mitochondrial density and size within muscle fibres, improving oxygen utilisation efficiency and the capacity for sustained ATP production through complete glucose and fat breakdown.
- Varied intensity training programs improve overall energy system efficiency and enhance the smooth transition and interaction between different energy systems during changing exercise demands and intensities.
- Sport-specific intensity training leads to targeted metabolic adaptations within the predominantly used energy system, such as increased glycolytic enzyme concentration in sprinters or enhanced aerobic capacity in endurance athletes.
- The principle of training specificity ensures that energy system adaptations closely match the intensity demands and duration characteristics of the athlete’s competitive performance requirements.
