教授17年“日行万步”走掉三高

2017-08-23 09:58:02   中国青年网

每天朋友圈晒步数,总有人誓夺高地,可有的晒着晒着就曝出各种健康隐患。于是,一些批评走路养生的文章开始多起来。

近日,我国著名心血管内科专家胡大一教授起身力挺“日行万步”,并表示已经坚持17年,体重下降了22公斤,重度脂肪肝走没了,升高的甘油三酯也下降了,至今血压正常。

女子日行万步患滑膜炎

38岁李琴去年下载了一款软件,专门记录每日步行的步数以及消耗的卡路里。软件里还设专门的交流圈,可分享走路的步数,互相监督。

从此,李琴就一发不可收拾,每天努力走上1万步,截图发朋友圈打卡。有时心血来潮,还会多走半个小时以上。可没过几个月,她就发现自己的右脚出现了问题,脚后跟疼痛难忍,触地更痛,到附近医院骨科检查,诊断为滑膜炎。

武汉市普爱医院运动医学科主任张青松表示,走路值得推崇,一般人每周锻炼三四个小时就足够,但过量的运动让关节、肌肉都无法承受,容易造成劳损。此外,最好选择软的鞋子和地面,步行时步态要正确,放松走大步,用脚后跟着地,过渡到脚的外侧,再到前脚掌,培养正确的走路姿势。

健康走可改变化验指标

医学界公认,快走是最简便有效的运动方式,对高血压、糖尿病、血脂异常、肥胖等问题,不仅可改变化验单上的相关指标,还能显著改变患者的生活质量,延长寿命。

2017年《美国骨科与运动物理治疗杂志》介绍,健身跑的人关节炎发生率仅3.5%,而选择静息生活方式、久坐不动人群的关节炎发生率却为10.2%,竞技体育的赛跑者的关节炎发生率13.3%”,结论:健身跑有益于关节健康。

到底怎么个跑法既能保护心脏,又爱护关节呢?胡大一教授2003年已有膝关节病,有医生建议他考虑换关节,尽管右后脚跟有明显疼痛,还有椎间盘滑脱,行走中右腿发麻的症状,他仍日行万步,“坚持运动,肌肉强有力了,对关节还有保护作用。”

他坚持了17年,体重下降了22公斤,重度脂肪肝走没了,升高的甘油三酯也下降了,至今血压正常。

如何走路护心又护关节

胡大一教授的方法是每天有氧运动30分钟,即有效步数30分钟一次完成,而非“零敲碎打”,走走停停。

人的极量运动最大心率是220减去年龄,中等强度有氧运动达到的心率是最大心率的60%-80%,也可跟着感觉走,快步30分钟时,出现适度心悸气短、微汗就很合适。老年人可以稍慢一些,这样才有利于降脂降糖,控制紧张感,减轻抑郁焦虑。

他提醒,健步走时,手臂要摆起来,有利于锻炼手臂与胸部肌肉。也可使用行走手仗,这对老人行走上下坡,既成为安全辅助,还能帮助运动前后热身、放松。

如今,他每天仍不少于万步路,“我理解不必过于刻板,要个体化,循序渐进。兼顾安全与效果。”他强调,更重要的是改变人的活法,改变不健康的生活方式和行为,毕竟健康的第一责任人是自己。 记者祁燕
