時差N小時:運動可提高IQ

Stretching and toning are certainly important, buttheir benefitsare different from that of aerobicexercise.

伸展和拉伸顯然很重要，但是，對身體的益處有別于有氧運動。

Surprisingly,aerobic exercise isn't just beneficial toyour heart, it alsosharpens your mind.

意想不到的是有氧運動不僅僅有益身心，還能靈活大腦。

You don't have to be a jock to enjoy the brainbenefits of aerobic exercise.

享受有氧運動對于大腦健康的福利，并不一定要向運動員般劇烈運動。

Moderateaerobic exercise is plenty.

適度有氧運動就獲益頗多了。

Several studies involving older adultsdemonstrated that simply walking a mile or so three timesa week,increases blood flow in the brainand strengthens connections between neurons, resultingin improved mental performance ontasks requiring attention.

一些有關老年人的研究證實，只需每周三次散步一英里左右就能促進大腦血液循環(huán);增強神經元間的“互動”，提高注意力，從而提升智力。

One of the studies divided a group of seniors into two different six-month exercisecoursesonecourse consisting of aerobic exercise,the other consisting of stretching and toning.

一項研究將老人們分為兩組：一組做有氧運動;另一組做伸展和無氧拉伸半年的時間。

Again, we'renot talking about marathon-training here.

但是，運動量都是適度的而非馬拉松式。

The aerobic-training course gradually built itsparticipants up to walking 45 minutes at amoderate pace three times a week.

有氧運動組讓老人們養(yǎng)成了每周三次45分鐘正常步伐走路。

At the end of the course, the people who completed the aerobic training showedsignificantimprovements in attention-related mental tasks.

有氧運動訓練完后，參加者在注意力相關的智能測試有顯著提升。

The stretching and toning group showed littleimprovement.

而后一組受訓前后并無明顯差異。
