【摘要】：目的:探究中等强度定速身体锻炼期间不同时段的主观体力感知评级(RPE)、心肺活动状态和情绪状态,并进而推断RPE作为测评指标的精确性。方法:60名被试在跑台上完成中等强度定速跑或走30 min,并在实施前5 min、期间30 min和之后10m in进行RPE、情绪状态自行测评以及生理指标同步监测;将45min均分为9个时段并选择锻炼期间第1时段(t_1)、第2时段(t_2)、第3时段(t_3)、第4时段(t_4)、第5时段(t_5)、第6时段(t_6)的测试数据进行统计和分析;兼顾实验末的访谈核实结果。结果:RPE,t_3、t_4最小,t_2、t_5其次,t_1、t_6最大;心率(HR)t_6高于其余5个时段;耗氧量(VO_2)、相对耗氧量(VO_2/kg)、代谢当量(MET),6个时段基本恒定;积极情绪状态,t_2、t_3、t_4、t_5最佳,t_1其次,t_6最差;消极情绪状态,t_6最甚,t_5其次。结论:身体锻炼期间的心肺活动状态变化与RPE变化很不一致且处于积极情绪状态时伴随RPE低估于HR现象,故若将RPE作为中等运动强度测评指标则需兼顾情绪状态等第三变量的影响;身体锻炼期间,1/4被试进入了一种宁静的自我状态。
[Abstract]:Objective: to explore the subjective physical perception rating (RPEP), cardiopulmonary activity state and emotional state in different periods during moderate intensity constant speed physical exercise. And then infer the accuracy of RPE as the evaluation index. Methods: 60 subjects completed moderate intensity running or walking at a fixed speed for 30 mins on the platform, followed by 5 minutes before, 30 min and 10 min after the implementation, self-assessment of emotional state and birth. Synchronous monitoring of physical indicators; The 45 minutes were divided into 9 periods and selected for the first time during the exercise period. The second time was tipped off, the third time was tipped, the third time was tipped, the fourth time was tipped, the fifth time was tipped, and the sixth time was the season 6. The statistics and analysis of the test data were carried out. The results of the interview at the end of the experiment were as follows: 1 / RPET / T / S / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T / T /. Conclusion: the changes of cardiopulmonary activity and RPE during physical exercise are not consistent with those of RPE and RPE understates HR when they are in a positive emotional state. Therefore, if RPE is taken as the index of moderate exercise intensity, the influence of the third variable, such as emotional state, should be taken into account, and a quarter of the subjects entered a quiet self-state during physical exercise.
