长期步行锻炼对低劳动强度人群健康状况的影响

Effects of long-term walking exercise on health status of low labor-intensity people

目的探讨长期步行锻炼对低劳动强度人群健康状况的影响。方法招募北京某高校志愿教师100人,体检后随机分为观察组和对照组,观察组定期开展相应鼓励活动并记录每日步数,450 d后再次体检测量健康指标。结果观察组共有45.24%的参与者获得了75%以上的参与率,且参与率越低,每日步数越少(P<0.05);参与度<25%组空腹血糖、收缩压、低密度脂蛋白胆固醇及总胆固醇均低于参与度较高的组P<0,05);低活动量组(<7 500步/d)组体重指数、收缩压、空腹血糖、总胆固醇、糖尿病及高血压比率低于较高活动量组(P<0.05)。结论步行锻炼能在不断反馈激励下获得良好的长期坚持,对于年龄较大及初始检查指标较高的参与者在鼓励指导下更容易使参与率和运动量达到较好水平,坚持长期步行锻炼有助于减缓血压、血脂的升高。

Objective To investigate the effect of long-term walking exercise on the health status of low-labor-intensity population under long-term walking exercise. Methods A total of 100 volunteer teachers from universities in Beijing were enrolled. After physical examination, they were randomly divided into control group and observation group. The observation group regularly carried out corresponding encouraging activities and recorded the daily number of steps. The corresponding indexes were measured again after 450 days. Results 45.24% participants in the observation group got more than 75% participation rate. The lower the participation rate, the lower the average daily steps （P 〈 0. 05）. The fasting blood glucose, systolic blood pressure, LDL and total cholesterol were lower than other groups in the group participation rate 〈25% （P 〈0,05）. The body mass index, systolic blood pressure, fasting blood glucose, total cholesterol, ratio diabetes and hypertension in low activities group （ 〈 7 500 steps/day） were lower than those in other groups （ P 〈 0. 05 ）. Conclusions Walking exercise can achieve good long-term persistence with con- stant feedback. For those who are older and whose initial indicators are higher, participation rate and exercise volume are more likely to be better under the guidance of encouragement. Persisting long-term walking exercise can help reduce blood pressure and blood lipids.
