户外运动强度测定与定级
Measurement and Classification of Outdoor Exercise Intensity

目标：制定一套适用于大众的户外运动强度测定和分级方法。方法：由于总心跳数与耗氧量成正比，我们利用总心跳数作为运动强度的指标。通过实验建立总心跳数与徒步、登山两种运动形式中前进速度、爬升速度、前进负重、爬升负重四种运动因素的关系，结合个体差异归纳出有氧运动下户外运动强度的计算公式。并参考人群经验，制定适用于大众的户外运动强度分级方法。结果：各因素与运动强度的关系、通过大众易于得到的数据计算运动强度的总公式和基于此的户外运动强度分级方法。此方法结合智能手机测量，便于推广。
Aim: This study aimed to develop a measurement and classification method of outdoor exercise intensity suitable for the public. Method: Since the total heartbeat is proportional to the oxygen consumption, we used the total heartbeat as an indicator of exercise intensity. We conducted experiments to establish the relationship between total heartbeat and four exercise factors of forward walking speed, climbing speed, walking with weight-bearing and climbing with weight-bearing in the two exercise forms of hiking and mountaineering. The calculation formula of outdoor exercise intensity under aerobic exercise was deduced by combining individual differences, and a clas-sification method of outdoor exercise intensity suitable for the public was formulated with reference to population experiences. Results: The results included the relationship between each factor and exercise intensity, a formula for calculating exercise intensity from data readily available to the public, and a grading method for outdoor exercise intensity based on this. This method, if combined with smartphone measurement, is convenient for promotion to the public.
