不过，是只听音乐就能产生这种效果，还是说，真正减轻体力劳动的痛苦的，其实是创作音乐的过程？

为了一探究竟，科学家分别让受试者在两种情况下使用健身器材。第一个试验中，受试者只是边运动边听音乐；而在第二个试验中，只有当受试者使用健身器时才能带动音乐播放，并且，音乐播放的快慢取决于他们运动的速度。

研究人员测量了受试者的耗氧量和肌张力，发现第二个试验中的那些能够控制音乐速度受试者消耗的能量更少，这些受试者……[查看全文]

Music Helps You Work Harder

Music helps us get through hard, physical work. Think of the songs produced by soldiers marching or chain gangs building railroads.

But does simply hearing the music account for the effect? Or is there a bigger boost when the workers themselves make the music?

To find out, scientists had subjects exercise on a fitness machine under two conditions. In one trial, the volunteers just listened to music. In the second run, the machines were rigged to start playing music only when the participant began to move. And the pace at which the subject exercised determined the speed of the music.

Measurements of the participants’ oxygen intake and muscle tension showed that they actually expended less energy when they controlled the music. The participants also...[full transcript]
