持久坐在室内进修上班的你，可能早就想出门做做运动了，不外先等等，出门前不如先看看一项研究：科学家发现，并非所有人都能从有氧运动中得到益处。那项研究颁发于《利用心理学杂志》（Journal of Applied Physiology）。

为了连结安康，许多人城市抉择慢跑、泅水或者是往健身房，制止患上心脏、糖尿之类的疾。有氧运动理论上是一种有效的健身体例，因为它能够磨练心肺，让全身的血液加速活动，从而进步一项喊做“更大摄氧量”（VO2 max）的目标，也就是运动时组织细胞所能消耗或操纵的氧气更高值。更大摄氧量越高，意味着你越安康。但在那项研究中，科学家发现严厉的有氧运动其实不会明显进步所有人的更大摄氧量：研究中有五分之一的受试者……

Aerobic Exercise Boosts Fitness--For Most

You’ve probably promised yourself to get off the couch and get some exercise. But before you get up, you might be interested to know that new research suggests that not everyone will benefit from a good aerobic workout. The study appears in theJournal of Applied Physiology.

Many of us jog or swim or hit the gym in an attempt to keep fit, and to help ward off ailments like heart disease and diabetes. And aerobic exercise, which really gets your heart pumping and your blood flowing, is supposed to be the way to go. Because cardiovascular training generally increases what’s called the VO2 max, which is a measure of your ability to get oxygen to your hardworking muscles. The higher your VO2 max, the more fit you are. But in this study, scientists found that rigorous exercise does not boost everyone’s VO2 max. One in five participants...
