【摘要】：目的:评估16周前后运动后心率恢复(HRR)测试重复性,为HRR在健康体适能中的应用提供方法学依据。方法:80名20~59岁健康成年人,在相同实验条件下完成两次递增功率自行车运动测试,间隔时间为16周。运动终止后取坐位恢复3 min。记录运动后第1 min末(HRR1)、第2 min末(HRR2)和第3 min末(HRR3)心率恢复绝对值和各时间点相对值(△HRR)。整个研究过程,受试者保持正常生活习惯,无规律性体育锻炼。使用组内相关系数(ICC)、变异系数(CV)评价两次测试结果的重复性,应用Bland-Altman散点图法对两次测试数据进行一致性评价。结果:16周前后受试者的健康风险因素无明显变化。两次测试运动终止强度分别为年龄最大心率预测值的93.3%±5.3%和92.8%±4.6%(P0.05),VO2peak也无统计学差异(P0.05)。两次运动后心率恢复测试结果均值无统计学差异(P0.05),效应量小(ES0.2)。运动恢复期各时间点上心率恢复绝对值的ICC0.73,尤其是HRR1表现出极高的重复性(ICC=0.915)。与恢复期各时间点心率恢复相对值相比,绝对值测试数据的变异系数相对较小,Bland-Altman散点图显示绝对值测试结果的95%的一致性界限范围较窄,两次测试结果一致性明显高于△HRR。运动恢复时间延长,心率恢复绝对值重复性越差,而△HRR重复性越高。结论:健康成年人16周前后运动后心率恢复测试结果具有较高的一致性,尤其是运动后第1 min末心率变异性小、可靠性高。
[Abstract]:Objective: to evaluate the repeatability of heart rate recovery (HRR) test after exercise for 16 weeks and to provide methodological basis for the application of HRR in healthy physical fitness. Methods: 80 healthy adults aged 2059 years were enrolled in this study. Under the same experimental conditions, we have completed two tests of incremental power cycling, The interval was 16 weeks. The sitting position was recovered 3 minutes after exercise. The absolute value of heart rate and the relative value of each time point (HRR3) were recorded at the end of 1 min after exercise, the end of 2 min (HRR2) and the end of 3 min (HRR3). The subjects maintained normal living habits and had no regular physical exercise. The reproducibility of the results of the two tests was evaluated by using the intra-group correlation coefficient (ICCX) and the coefficient of variation (CVV). The Bland-Altman scatter plot method was used to evaluate the consistency of the two test data. Results there was no significant change in the health risk factors of the subjects before and after 16 weeks. The exercise termination intensity of the two tests was 93.3% 卤5.3% and 92.8% 卤4.6 respectively of the maximum heart rate predictive value of age (93.3% 卤5.3%) and 92.8% 卤4.6% (P0.05VO _ 2peak), respectively. There was no statistical difference (P 0.05). There was no significant difference in the mean value of heart rate recovery test after two exercises. There was no significant difference in the mean value of heart rate recovery between the two exercises. ICC 0.73, especially in HRR1, showed a very high reproducibility with that of restoring the absolute value of heart rate at different time points during exercise recovery period. Compared with the relative value of heart rate recovery at different time points in the resuscitation period, The coefficient of variation of the absolute test data is relatively small. The Bland-Altman scatter plot shows that the consistency limit of 95% of the absolute value test results is narrower, and the consistency of the two test results is obviously higher than that of HRR.Motion recovery time is prolonged. Conclusion: the results of heart rate recovery test of healthy adults after 16 weeks exercise have higher consistency, especially the low heart rate variability and high reliability at the end of 1 min after exercise.
