Six seconds of exercise can transform health 運動6秒可改造健康

◎國際新聞中心

Short six-second bursts of vigorous exercise have the potential to transform the health of elderly people, say researchers in Scotland.

短短6秒鐘的一陣激烈運動，有可能改變年長者的健康，蘇格蘭研究人員說。

A pilot study involving 12 pensioners showed going all-out in very short bursts, reduced blood pressure and improved general fitness over time.

一份請12名退休人士參與的試驗性研究顯示，在非常短時間內使盡全力運動，可降低血壓，還可逐漸提升整體健康。

High Intensity Training （HIT） has attracted a lot of attention for promising some of the same benefits as conventional exercise but in a much shorter time. Instead of a comfortable half-hour jog or a few miles on the bike, HIT involves pushing yourself to your limits for a short period of time.

高強度訓練（HIT）保證具有傳統運動的某些好處，但花費時間少很多，因此吸引許多人注意。高強度訓練不是舒適的半小時慢跑，或是騎數英里的腳踏車，而是要在短時間內將自己推到極限。
