産業労働者の身体活動量,身体活動パータン : 健康維持,増進の観点から

Abstract

Information about the amount of daily physical activity in the workers is not only of theoretical interest, but also such knowledge is essential for determining and designing physical conditioning programs for the workers. The purpose of this study was to assess the amount of physical activity or the activity pattern of the workers in daily living, using the pedogram technique in which the pedometer count was recorded successively every thirty seconds for waking-time. Twenty-five males and three females, aged 38.8±5.5 years, were recruited as subjects. The subjects were asked to attach the pedometerrecorder (pedocorder) at their waist successively for two days except during bath- and sleeping-time.The step count for the sedentary workers was averaged 5213±1667 counts/day and that of non-sedentary workers was 10328±3660 counts/day, more than for sedentary workers with a statistical significance level. The distribution of the pedometer count per minute showed 79.9±5.9% (sedentary workers) and 61.0±8.5% (non-sedtary workers) of the allocated time spent at a pedometer count of O count/min, There was statistical significance difference between sedentary and non-sedentary. The duration of the exceeding 91 counts/min corresponding with the training threshold for physical fitness, occurred 1.4± O.5% (12.3 min/day) in the sedentary workers and 2.6±1.5% (23.9 min/day) in non-sedentary workers.It might be concluded from the results obtained in this study that physical activity in daily living of the sedentary workers did not attained the training threshold, in both quantity and quality.
