随着运动体育与生理科学的日益紧密结合,越来越多的运动生理学之谜正在揭开。Detection-1、运动强度决定消耗体能不同运动利用何种能量决定于运动强度和时间。例如2.5公里越野跑系充氧供能,主要依靠肌磷酸和乳酸系统,消耗的主要能量是脂肪。5公里越野跑则系高强度需氧运动,需要心肺系统尽量为横纹肌运动提供氧气,每升氧横纹肌利用糖能产热5.05千卡,利用脂肪只产生3.69千卡,因此消耗糖比较有利。
With the increasingly close combination of sports and physical science, more and more mysteries of sports physiology are being uncovered. Detection-1, the intensity of exercise determines how much energy is consumed by different exercises, and the intensity and time of exercise. For example, 2.5 km trail running oxygenation system, mainly rely on muscle phosphate and lactate system, the main energy consumed is fat. 5 km cross-country run is the Department of high-intensity aerobic exercise, cardiovascular and cerebrovascular system as much as possible to provide oxygen for the striated muscle exercise, per liter of oxygen striated muscle use of sugar can produce 5.05 kcal, the use of fat only produce 3.69 kcal, so consume more favorable sugar.
