消耗什么看强度运动利用何种燃料决定于运动强度和时间。例如2.5千米越野跑是充氧供能,主要依靠肌磷酸和乳酸系统,消耗的主要燃料是脂肪。5千米越野跑则是高强度需氧运动,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
What to consume to see the intensity of exercise Which fuel depends on exercise intensity and time. For example 2.5 km trail running is oxygenation, mainly rely on muscle phosphate and lactate system, the main fuel consumed is fat. 5 km cross-country run is a high-intensity aerobic exercise, cardiovascular system as much as possible for the striated muscle to provide oxygen, per liter of oxygen striated muscle use of sugar can produce 5.05 kcal, the use of fat only produce 3.69 kcal, so consumption of sugar
