健身的六个常识误区

  Physical fitness is today's hot topic. And everywhere you turn you hear something new. But is it all true?

  保健是当今的热门话题。无论你走到哪里,你都听到新奇的事情。但是,那都是正确的吗?

  The more you sweat, the more fat you burn 流汗越多,消耗的脂肪越多

  This myth has encouraged people to work out in extreme heat or wear layers of clothes or rubber or plastic weight-loss suits in the hope of sweating fat off. Unfortunately, it's water they're losing, not fat.

  这个错误的观点鼓励人们在极热的环境下运动,或者穿好几层衣服或者穿橡胶或塑料

减肥服,希望通过流汗将脂肪排出。不幸的是,排出去的是水而不是脂肪。

  Fat burns when it is used as a fuel source for exercise, which doesn't happen initially. When you first begin to exercise, you burn carbohydrates or sugars. It takes about 20 minutes of easy to moderate aerobic activity before the transition from burning sugars to fat begins. (Aerobic exercise is any rhythmic and continuous activity that uses oxygen and large muscle masses of the body, such as the arms and legs. Examples are bicycle riding, jumping rope, walking, jogging, aerobic dance, and swimming.) So, to burn the flab, plan on working out at least 40 minutes.

  作为一种燃料能源,脂肪只是在运动时才消耗。而且并不是在运动初始阶段就能奏效。当你开始运动时,你消耗的是碳水化合物,或者糖类。平缓进行有氧运动大约20分钟才会使你由消耗糖类向消耗脂肪过渡。(有氧运动就是有节奏的、持续的活动。它需要耗氧并且锻炼像手臂和腿部的大块肌肉。例如骑自行车、跳绳、步行、慢跑、跳舞和游泳)。所以说,要消耗脂肪,至少要运动40分钟。
