摘要
目的:探讨两种运动强度处方对甲基苯丙胺(methamphetamine,MA)戒断者心肺适能的改善效果,并比较两者的优良性。方法:75名男性MA戒断者被随机分为3组:不运动对照组、最大心率百分比(percentage of _(max)imum heart rate,%HR_(max))组、通气无氧阈(ventilatory anaerobic threshold,VAT)组。运动组执行每天50 min,每周5天,共12周,但运动强度不同的有氧训练方案:1)采用%HR_(max)法设定运动强度(64%~76%HR_(max));2)采用VAT心率值设定运动强度。结果:与运动前相比,运动后%HR_(max)组的VO_(2max)显著升高(P<0.05),总胆固醇、甘油三酯和血糖显著降低(P<0.05);VAT组的VO_(2max)、最大心率显著升高(P<0.05,P<0.01),体质量、腰围、体脂率、甘油三酯和血糖显著降低(P<0.05)。与%HR_(max)组相比,VAT组在12周时体脂率显著降低(P<0.05),最大心率和VO_(2max)显著升高(P<0.05),且VAT组所有受试者均产生了个体VO_(2max)训练反应。结论:基于VAT和%HR_(max)法建立的运动强度处方均能降低MA戒断者血糖和血脂,但基于VAT的运动强度处方能够显著提高VO_(2max)并引起更多的个体VO_(2max)训练反应。
Objective:To explore the effects of two exercise intensity prescriptions on the cardiopulmonary fitness of methamphetamine(MA)withdrawal patients and compare the superiority of the two.Methods:75 male MA withdrawal subjects were randomly divided into 3 groups:non-exercise control group,percentage of maximum heart rate(%HR_(max))group,and ventilatory anaerobic threshold(VAT)group.The exercise group performed 50 minutes a day,5 days a week,a total of 12 weeks but different exercise intensity aerobic training program:1)Using%HR_(max) method to set the exercise intensity(64%-76%HR_(max));2)Using VAT heart rate value set exercise intensity.Results:Compared with before exercise,after exercise,the VO_(2max) of the%HR_(max) group was significantly increased(P<0.05),and total cholesterol,triglycerides and blood sugar were significantly reduced(P<0.05);the VO_(2max) and maximum heart rate of the VAT group were significantly higher increased(P<0.05,P<0.01),weight,waist circumference,body fat percentage,triglycerides and blood sugar were significantly reduced(P<0.05).Compared with the%HR_(max) group,the body fat rate of the VAT group was significantly lower at 12 weeks(P<0.05),the maximum heart rate and VO_(2max) were significantly increased(P<0.05),and all subjects of the VAT group generated individual VO_(2max) training response.Conclusions:Exercise intensity prescriptions based on the VAT and%HR_(max) methods can reduce blood sugar and blood lipids in MAwithdrawals,but exercise intensity prescriptions based on VAT can significantly increase VO_(2max) and cause more individual VO_(2max) training responses.
