最近一项发表在《美国心脏病学会期刊》(Journal of the American College of Cardiology)上的研究显示,相比于那些从来不跑步的人来说,每天只跑步几分钟或者只是慢跑也能显著降低人们因心血管疾病死亡的风险。

众所周知,锻炼能够预防心脏疾病的发生,同时它也是健康生活不可或缺的一部分。美国政府以及世界卫生组织建议每周进行75分钟的高强度运动(比如跑步),但如果锻炼时间达不到这个要求,运动又能带来多大益处呢?这一点人们还不是很了解。

在此次的研究中,研究人员在15年间调查了55137位18到100岁的成年人,以此来确定跑步和长寿之间是否存在联系。研究数据来自于有氧中心纵向研究(Aerobics Center Longitudinal Study),参与者需要完成一份关于跑步习惯的调查问卷。在整个追踪调查过程中,有3413位被调查者死亡,其中1217位死于心血管疾病。在这些人中,有24%的人表示跑步是他们闲暇运动的一部分。

与那些不跑步的人相比,跑步的受访者死亡风险降低了30%,因心脏病或脑卒中死亡的风险降低了45%,平均寿命增加了3年。作者认为,从公共健康的角度来看,鼓励人们跑步应该放到和控制吸烟、肥胖以及高血压相同的高度。无论跑步的频率和时间如何,人们都能从中获益。性别、年龄、体重指数(BMI)、健康情况、吸烟以及酗酒状况等因素也并不影响跑步带来的好处。

研究显示,每周跑步不足51分钟、距离不超过6英里、速度不超过每小时6英里,或者每周只跑一两次的受访者,他们的死亡风险也要比那些不跑步的人低。研究人员同时还关注了被调查者的跑步习惯,他们发现平均坚持跑步六年的人群中健康收益最为显著,他们的死亡风险降低了29%,因心脏病或卒中死亡的风险降低了50%。

“时间无法保障是阻碍人们参与锻炼的最大障碍,这项研究能够刺激更多的人开始跑步并坚持下去,这样的健康收益简直伸手可得。”论文作者这样说到,“对于那些久坐不起但身体健康的人来说,跑步也许是一个很不错的选择。相比15到20分钟较低强度的活动,每天跑上5到10分钟或许是更好的选择,这样耗费时间更少,也能起到相近甚至更好的效果。”

JAMA:你知道跑步带来的损伤吗?

超过400万美国人都有跑步的习惯。跑步虽然能给人们带来健康,但也同样会引起损伤。这类损伤大多为反复性,少部分为一次性创伤,通常会影响腿部的骨骼、肌肉、肌腱和关节。在2014年7月9日的JAMA杂志上对跑步损伤进行相关评述,全文编译如下。 跑步损伤的一般症状有哪些? 跑步人群中最常见的症状是膝关节疼痛,其原因大多是由髌股关节疼痛综合征(patellofemoral pain syndrome )

MSSE:跑步对膝关节利大于弊

据台湾《联合报》报道,一般人多认为跑步比起其它运动更伤膝,不过,最新的研究指出,跑步对于关节的影响,较走路及其它运动更小。 这份刊登在《运动医学期刊》的美国研究,追踪近90,000名跑步族群及健走族群发现,跑步族群中,罹患退化性关节炎或接受髋关节置换术的人,比健走及其它运动来得少。 研究分别追踪74,542名跑者7.1年,以及14,625名健走者5.7年,分析两个族群运动的频率、强度以及年纪、
