FASEB J:高强度冲刺训练可能有害健康

近期发表在The Federation of American Societies for Experimental Biology (FASEB) Journal的研究称,积极的生活方式有益身体健康,但一些极端的锻炼形式并不适合每个人。

只需要在健身房里通过2分半钟的高强度“全力冲刺”锻炼就可以额外消耗200卡路里,想减肥或燃烧脂肪的人看着这个心动了吗?

并且,强烈的运动训练能刺激线粒体的生长,增加机体用氧能力、增强心血管健康、增强体质、预防心血管疾病和肥胖。

但是,如果在进行高强度锻炼之前不做好运动准备,那么就等着高强度运动损害身体吧!

英属哥伦比亚大学运动机能学的主任Robert Boushel和来自加拿大、欧洲的研究人员对来自瑞典的12名志愿者的组织标本进行了分析。

所有参与者都是健康的人群,区别在于未经训练还是适度活动。志愿者参加了超过2周的高强度训练,运动方案包括30秒的全力冲刺,然后休息。

研究人员观察到,参与者进行超高强度腿部和手臂运动后,肌肉组织出现了紧张的迹象。

检测后研究者发现,高强度训练后,志愿者的线粒体能力只有先前的一半,消耗氧气的能力下降了,对抗自由基损害的能力也下降了。

自由基是可以损伤DNA的分子,对健康细胞造成伤害。高水平的自由基有害身体健康,包括过早老化、器官损伤和癌症等。

研究结果表明,不应该鼓励普通民众参与冲刺训练,或训练前要对参与者进行评估,是否能胜任这种强度的锻炼。训练有素的运动员与普通民众不同,他们的体内积累了相当多的抗氧化酶,为对抗自由基提供足够的保障。

所以对于初学者,应该遵循循序渐进原则,并且训练也应该在受过训练的专业人士或运动学家的指导下进行。虽然高强度冲刺训练可以更好更快的燃烧脂肪,但是对你而言可能并不是健康的方式。

虽然目前高强度短跑训练的长期不利影响是未知的,但是正在进行的研究正在探究,不同强度和数量的运动对健康的不同影响。

CCC 2015:新近诊断的糖尿病患者该如何运动才更有效

体育锻炼是糖尿病康复不可或缺的一部分。从历史上看,糖尿病康复采用低强度、持续运动。最近的研究证实高强度锻炼对代谢疾病有短期的好处。这种短时间高强度运动对糖尿病患者的影响还没有充分评估。一项新研究表明,对2型糖尿病患者,短时间高强度的运动与持之以恒的低强度运动相比,可以显著改善患者心血管代谢危险因素 。该研究纳入了76名新近诊断的糖尿病患者,将其随机分为对照组(年龄预测目标心率值的60%持续30分钟
