高强度间歇训练(HIIT)除了减脂还有什么好处?

开始运动并想要快速减脂的你,一定听过高强度间歇训练(High Intensity Interval Training,简称HIIT)吧!

什么是HIIT?

HIIT是结合了高强度训练及间歇训练而成的运动类型,强度较高且具爆发力的运动即称为高强度训练。人类通过高强度的运动,让身体中的肌肉感受到疲劳、进而开始消耗大量氧气。 高运动强度让身体耗氧量逐渐接近最大摄氧量(身体在运动时可以消耗的氧气量最大值),并启动一种机制叫做「后燃效应 After-burn Effect」。简单来说,后燃效应就是可以让身体在停止运动之后,还能继续消耗氧气,继续消耗热量。

间歇训练就是将运动内容分段交叉进行,例如:动-停-动-停,或是高强度-低强度-高强度-低强度交替的方式。简单来说,这类型的运动特色在于通过短时间的高耗能运动加上短暂歇息的方式来减脂。

解释完HIIT,我们就可以来看看世界卫生组织(WTO)如何建议:「18-64岁的成年人应该在一周内完成至少150分钟的中等强度有氧运动,或者在一周内进行至少75分钟的剧烈有氧运动,或者进行中等强度和剧烈运动的等效组合。」。因此,HIIT训练开始受到全球的关注。

HIIT的特色

HIIT训练结合了短时间与高强度的运动爆发性,在一个15-20分钟的短时间训练中,重复高强度与低强度的阶段,在练习时的最大心率为85-100%而不是中等训练活动的50-70%。从本质上讲,HIIT可以在任何地方进行,还能进行任何类型的锻炼及训练。HIIT训练的一个主要好处是:它们可以在没有任何设备或设备最少的家中进行,例如,自行车也能进行这种训练,你可以以最大速度骑行20秒再放松骑行20秒,然后重复该循环10-20分钟。
