要吃什么/做什么才可以补脚力？

本人已经5年没有运动了。。
最近开始跑步，发觉我的脚不能tahan久
就是说我跑了一阵，虽然呼吸有点辛苦但是脚却酸酸无力
被逼停下来走

所以要吃什么/做什么才可以补脚力？ ？

可能是心肺弱了点。
详细要查过才知道。

这个根本和“吃什么”没有甚么关系。

这是身体的基本生化反应使然。在无氧状态下产生了lactic acid,这个lactid acid 堆积在你的肌肉里，造成你酸痛的感觉。

The lactic acid system is capable of releasing energy to resynthesise ATP without the involvement of oxygen and is called anaerobic glycolysis. Glycolysis (breakdown of carbohydrates) results in the formation of pyruvic acid and hydrogen ions (H+). A build up of H+ will make the muscle cells acidic and interfere with their operation so carrier molecules, called nicotinamide adenine dinucleotide (NAD+), remove the H+. The NAD+ is reduced to NADH which deposit the H+ at the electron transport gate (ETC) in the mitrochondria to be combined with oxygen to form water (H2O).

If there is insufficient oxygen then NADH cannot release the H+ and they build up in the cell. To prevent the rise in acidity pyruvic acid accepts H+ forming lactic acid which then dissociates into lactate and H+. Some of the lactate diffuses into the blood stream and takes some H+ with it as a way of reducing the H+ concentration in the muscle cell. The normal pH of the muscle cell is 7.1 but if the build up of H+ continues and pH is reduced to around 6.5 then muscle contraction may be impaired and the low pH will stimulate the free nerve endings in the muscle resulting in the perception of pain (the burn). This point is often measured as the lactic threshold or anaerobic threshold or onset of blood lactate accumulation (OBLA).
