Abstract

The daily level of physical activity was estimated using the heart rate monitor, PE3000 (Polar Electro, Finland). The level was expressed with the coefficient of variation (CV) of heart rates recorded from waking time to dinner time. In the course of a day of intense physical activity, CV was confirmed to rise significantly. Then the CV was estimated and compared among 3 age classes, young (10-18 years), middle-aged (30-47 years), and elderly (62-76 years). The CVs of young people were significantly higher than those of middle-aged (P < 0.001) and elderly (P < 0.01), regardless of sex. However there was no significant sex difference in all age classes. These results suggest that the CV is an accurate index of daily physical activity. Thus clinicians can use the CV of heart rates to estimate the level of physical activity of individuals which closely relates to QOL.

摘要

使用芬兰 Polar Electro 公司生产的 PE3000 心率监测仪估算每日身体活动水平。该水平以从醒来到晚餐时间记录的心率变异系数（CV）表示。在一天的高强度身体活动过程中，CV 被证实显著上升。然后在三个年龄组中估算并比较 CV，即年轻人（10 - 18 岁）、中年人（30 - 47 岁）和老年人（62 - 76 岁）。无论性别如何，年轻人的 CV 显著高于中年人（P < 0.001）和老年人（P < 0.01）。然而，在所有年龄组中均未发现显著的性别差异。这些结果表明，CV 是每日身体活动的准确指标。因此，临床医生可以使用心率的 CV 来估算与生活质量密切相关的个体身体活动水平。
