Sample Answer
Similarities:
- Both training methods require specific time durations to target their respective energy systems effectively.
- Both need sufficient time to create training stimulus and promote fitness improvements.
- Both require planned recovery periods, though at different intervals.
Differences:
- Glycolytic training uses short work intervals of 30-90 seconds targeting the lactic acid system.
- Aerobic training involves continuous activity lasting 20-60+ minutes at moderate intensity.
- Glycolytic sessions total 15-30 minutes of high-intensity work due to accumulated fatigue.
- Aerobic sessions extend much longer without excessive fatigue because of steady-state exercise.
- Glycolytic training requires work-to-rest ratios of 1:2-3 to allow partial lactate clearance.
- Aerobic training needs no rest intervals as steady-state exercise allows ongoing oxygen delivery.
Physiological responses from time differences:
- Shorter glycolytic intervals create metabolic stress, which improves lactate buffering capacity.
- This leads to enhanced glycolytic enzyme activity and better lactate removal.
- Longer aerobic duration stimulates cardiovascular responses resulting in improved oxygen delivery.
- Extended moderate intensity causes enhanced fat utilisation efficiency.
- These distinct responses reflect each energy system’s role in different performance demands.
