Sample Answer

ATP-PCr provides immediate energy for very high intensity but depletes rapidly within 10 seconds
Glycolytic system produces more ATP but takes longer to activate, sustaining high intensity for 30-90 seconds
ATP-PCr has no by-products while glycolytic produces lactic acid causing fatigue
Both systems can be trained for greater capacity but through different intensity protocols
