The maximal explosive power (wmax), i.e. the mechanical power developed over short bursts (less than 5 s) of all-out cycling, or uphill running, in humans attains 12-17 Wkg-1 in non athletics subjects. Thus, in terms of O2 consumption wmax is about four times larger than the subjects VO2max. The peak instantaneous power during a vertical jump off both feet (w) in non athletic subjects is about 50-55 W kg-1 and attains 70-75 Wkg-1 in "power" athletes. Both wmax and w decrease when the all-out efforts is performed from a priming aerobic exercise: if the intensity of this last approaches VO2max, then wmax and w are reduced to about 75% the value attained from rest. Thus, in the course of high intensity efforts, an athlete can develop a still remarkable fraction of his maximal absolute power. The decrease mentioned above is proportional, and presumably causally related, to the decrease of the high energy phosphate concentration occurring in the muscle at the onset of the exercise, and maintained throughout the effort duration.
最大爆发力（wmax），即人类在全力骑行或上坡跑的短时间爆发（少于5秒）中所产生的机械功率，在非运动员受试者中达到12 - 17瓦·千克⁻¹。因此，就氧气消耗而言，wmax约为受试者最大摄氧量（VO2max）的四倍。非运动员受试者双脚起跳垂直跳跃时的峰值瞬时功率（w）约为50 - 55瓦·千克⁻¹，而“力量型”运动员可达70 - 75瓦·千克⁻¹。当从热身有氧运动开始进行全力运动时，wmax和w都会降低：如果热身运动的强度接近VO2max，那么wmax和w会降至从静止状态开始时所达到值的约75%。因此，在高强度运动过程中，运动员仍能发挥出其最大绝对功率的相当一部分。上述降低是成比例的，并且可能与运动开始时肌肉中高能磷酸盐浓度的降低有因果关系，且在整个运动持续期间一直保持这种降低状态。
