摘　　要：背景:适宜运动强度的选择是制定个性化精准指导方案的关键。无氧阈强度是发展有氧耐力的最佳强度,常用无氧阈的测定需要在实验室环境下进行,步骤复杂、成本偏高,并且需要专业的人员计算分析,存在一定的局限性。目的:探索用20 m折返跑测试成绩结合性别、年龄、身高、体质量、运动情况等指标推测无氧阈强度的可行性,建立推测20-29岁成年人无氧阈强度的回归方程。方法:招募20-29岁受试者共计126人,其中男性61人,女性65人。首先采集性别、年龄、身高、体质量、运动情况等指标,然后利用功率自行车进行递增负荷运动试验(GXT)采集气体代谢指标并计算通气无氧阈(VT),择日进行20 m折返跑测试。根据各指标相关性分析结果,将通气无氧阈作为因变量,20 m折返跑测试成绩和其他相关指标作为自变量,采用逐步回归的方法建立回归方程。结果与结论:①20 m折返跑的总圈数与总样本的通气无氧阈绝对值中度相关,r=0.684(P <0.01);②20 m折返跑推测20-29岁成年人无氧阈强度回归方程为:通气无氧阈(L/min)=-0.201+0.008*总圈数+0.01*体质量+0.096*运动情况(R=0.828,R2=0.686,SEE=0.210);③提示:20 m折返跑推测20-29岁成年人无氧阈强度的方法可行,可用于指导大众科学、安全、有效健身。BACKGROUND:The selection of appropriate exercise intensity is the key to develop personalized and accurate guidance scheme.The anaerobic threshold intensity is the best intensity to develop aerobic endurance.The measurement of the commonly used anaerobic threshold needs to be carried out in a laboratory environment.There are certain limitations,including complicated steps,high cost,and professional personnel required for calculation and analysis.OBJECTIVE:To explore the feasibility of speculating the anaerobic threshold intensity by combining the results of 20-meter shuttle run test and the indicators of sex,age,height,body mass and exercise conditions,and to establish a regression equation to speculate the anaerobic threshold intensity of adults aged 20-29 years.METHODS:In total,126 participants were enrolled,aged 20 to 29 years,including 61 males and 65 females.Information on sex,age,height,body mass and exercise conditions was collected and recorded.Then Graded Exercise Test was conducted using a cycle ergometer,to collect gas metabolism indicators and calculate the ventilatory threshold(VT).A 20-meter shuttle test was conducted at a later date.According to the correlation analysis results of all indicators,the regression equation was established using the method of stepwise regression,with the VT as dependent variable,the results of 20-meter shuttle run test and other relevant indicators as independent variables.RESULTS AND CONCLUSION:The laps of 20-meter shuttle run test was moderately correlated with the absolute value of VT(r=0.684,P<0.01).The regression equation of speculating anaerobic threshold intensity in adults aged 20 to 29 is:VT(L/min)=-0.201+0.008*laps+0.01*weight+0.096*exercise condition(R=0.828,R2=0.686,SEE=0.210).To conclude,it is feasible using the 20-meter shuttle run test to speculate the anaerobic threshold intensity of adults aged 20 to 29,which can be used to guide the public to exercise scientifically,safely and effectively.
