体育行为改变中能量消耗测评方法的比较研究

Comparative Study on Evaluation Methods of Energy Consumption in Physical Behavior Change

在进行大众体育意识与行为改变研究时,需要对个体体育锻炼行为的能量消耗进行实时监测。Polar表仪器可以比较客观准确实时记录个体运动时的心率、负荷以及能量消耗,但如果用Polar表进行大规模人群的运动负荷监控,就比较耗时、费力,代价也特别昂贵。因此,在进行大众体育意识与行为改变的运动强度或能量消耗评价时,可采用比较简单易用的主观评定法,比如活动日志法和7日回忆法,但主观评定能否真实准确的反映人体运动时的客观能量消耗就是研究科学性的关键。为解决这一问题,本研究以大学生为被试对象,实验证明活动日志法、7日回忆法与Polar表测试法具有显著相关,能比较准确的反映个体客观能量消耗,可以在大众体育意识与行为改变试验中用来测试各个变化阶段的能量消耗。

In the mass sports consciousness and behavior change research,the need for individual physical exercise behavior of the energy consumption of real-time monitoring,Polar instrument can objectively accurate real-time recording individual movement of the heart rate,load and energy consumption,but if you use Polar form to the large-scale population movement load monitoring,it is time-consuming and laborious,costly it is very expensive.Therefore,in exercise intensity or energy of mass sports consciousness and behavior change consumption evaluation,the subjective evaluation method is relatively simple and easy to use,such as the Activity Log Method and 7'Day Recall,but the subjective assessment of key scientific research on energy consumption is the objective reflection of human motion.In order to solve this problem,in this study,college students as subjects,the experiment to investigate the correlation between Polar test method,Activity Log Method,7Day Recall,as well as the subjective evaluation method can accurately predict the students' sports consciousness and behavior change objective physical activity in each stage(energy consumption).
