什么是最大心率，如何粗略估算？
What is maximum heart rate and how is it roughly estimated?
最大心率是运动时心脏能达到的安全上限，常用“220减去年龄”粗略估算。运动时的目标心率通常保持在最大心率的一定比例区间内。
Maximum heart rate is the upper safe limit of the heart during exercise, roughly estimated as '220 minus your age'. Target training heart rate is usually kept within a certain percentage of this maximum.

运动后为什么要及时补水？
Why should we rehydrate after exercise?
运动时我们通过出汗流失水分和电解质，及时补水有助于维持体温和循环。少量多次、温水为宜，避免一次性猛灌。
During exercise we lose water and electrolytes through sweat, so rehydrating helps maintain body temperature and circulation. Drink small amounts frequently with lukewarm water rather than gulping all at once.
