What are interplay of the energy systems?Show answer
The systems do not switch on and off; they all contribute at all times, with one predominating depending on intensity and duration. At the start of any activity the ATP-PC system leads, the glycolytic system takes over as efforts continue at high intensity, and the aerobic system becomes dominant as intensity drops or duration extends. In a team-sport game the player relies on the ATP-PC and glycolytic systems for sprints and tackles, and on the aerobic system to recover and resynthesise phosphocreatine during low-intensity periods. The crossover point is set by intensity, not a fixed clock.
What are training principles?Show answer
Adaptations only occur if training is structured. Specificity means training must match the energy systems, muscle groups and movements of the sport. Overload means training above the normal demand to force adaptation, usually applied through the FITT variables (frequency, intensity, time and type). Progression means increasing overload gradually as fitness improves so the body keeps adapting without injury.
