Exercise and Health
Physical exercise increases the circulation of the blood.During ex-ercise a man's heart beats violently.Whenever a muscle works it be-comes warm,that is,more blood goes there.The heart forces blood into the muscle as quickly as possible.Exercise compels the body to use more oxygen and a larger quantity of waste matter is expelled from the body.This makes the constitution more healthy.
Physical exercise develops the muscles.Many a sportsman has big arms and legs,which are better adapted to hard work.The more a mus-cle is used,the harder and larger it becomes.
Physical exercise increases the appetite and favours digestion.A man who takes exercise needs more food than the one who does not.The reason is that the more energy he spends the more blood he uses.New blood requires food to keep it pure.

运动与健康
身体运动增加血液循环。在运动中人的心脏剧烈跳动。每当活动时一部分肌肉就会变热，因为更多的血液流到了那里。心脏使血液尽可能快地流到那部分肌肉。运动使身体消耗更多的氧气，大量的废物从体内排出。 这使得整个机体更加健康。
身体运动使肌肉发达。 许多运动员手臂和腿都很粗壮，这样能更好地适应艰苦的工作。 肌肉活动越多，它就会变得更坚硬更丰满。
身体运动增进食欲并利于消化。一个运动的人比不运动的人需要更多的食物。其原因是消耗的能量越多，所需要的血液越多。新的血液需要食物以保持纯净。
