“…enzymes associated with adenosine triphosphate resynthisis capacity and pyruvate-lactate interconversion are key determinants of sprinting speed. Sprint type training has its greatest effects on the phosphagen pathways, with lesser but significant effects on glycolytic or oxidative metabolism.
Intense, brief activities engage the phophagen pathway, especially in fast-twitch muscle fibers. Likewise, these pathways account for much of the energy yield during the transition from rest to exercise, or from one workload to another, in all fiber types. Although intramuscular ATP levels rarely drop more than 40-60%, several seconds of intense activity can virtually deplete creatine phosphate (CP); this is highly correlated with sprinting fatigue.
Creatine phosphate repletion is achieved oxidatively, with a biphasic time course characterized by initial rapid (half-time 20-22 seconds) and subsequent slow (half-time ~170 seconds) components.”

What does this mean?
It means that for your sprinting speed and lifting power to replenish your aerobic capacity must be at a high level as well. Everything is related.
