拆外刊（74）：坚持跑步能够抵消随年龄增大而导致的最大摄氧量的下降

摘自：英国版《跑步者世界》

原文标题：Consistent training can counteract age-related decline in your VO2 max

       对于长距离跑步者来讲，随着年龄的增长没有必要减缓速度。一项最新的研究表明，如果一个人一辈子都坚持锻炼身体的话，他就能够抵消与年龄有关的最大摄氧量的降低，换句话说，如果一个人几十年如一日跑步，那么其最大摄氧量，也就是在高强度运动中需要的氧气量是不会下降的，而那些整天不爱活动的同龄人的最大摄氧量却会随着年龄增大而下降。这个研究结果很有鼓舞性，因为都认为到了一定年龄，如70岁左右，其最大摄氧量就会呈断崖式下降，而实际情况是，从该项研究我们可以看出，最大摄氧量下降的原因是由于运动量减少造成的，而非由生日蛋糕上又增加的一只蜡烛造成的。

【英文原文】

Consistent training can counteract age-related decline in your VO2 max

WHEN IT COMES TO long-distance running, growing older needn’t mean slowing down. A recent study showed that lifelong exercise can counteract the age-related decline of your VO2 max. In other words, if you’ve been running consistently for decades, your VO2 max – the amount of oxygen you can use during intense exercise – will not decline at the same rate as it does in your more sedentary peers. That’s an interesting development, because it has long been believed that at a certain age – around 70 – people’s VO2 max falls off a cliff. By contrast, the study suggests that the steepest declines occur as a result of exercising less, not simply by adding another candle to your birthday cake.
