| Research Abstract |
Recently, the Ministry of Education, Culture, Sports, Science, and Technology reported that whereas body weight is increasing, physical fitness is declining in Japanese adolescents. Furthermore, previous reports cleared that increased body weight result from accumulated body fat, These trends appear to be attributable to changes in life style that include the declining level of physical activity. Accordingly, to solve these issues this study suggests that it is necessary for Japanese adolescents to establish a standard for physical activity energy expenditure, which is composed of physical activity intensity and time as factors. Therefore, firstly it is important to investigate total energy expenditure (TEE) or physical activity level (PAL) and to clear relationships between physical behavior and fitness simultaneously.
In the 2002 year, this study investigated the validity of activity record method (AR), heart rate method (HR) and accelerometer method (AC) in comparison with doubly labeled water (DLW) method. We grasped that AR and HR were effective method to understand the TEE as an average in a group of adolescents. AC could compare with amount of physical activity between groups. Further, AC could distinguish between walking and running in AC intensity 7. In the 2003 and 2004 years, according to previous opinions, we measured TEE in primary school students, junior high school students, high school students and undergraduates. Besides, we investigate the relationships between PAL and fitness. As a result of this study, it was indicated that PAL was raised by increasing amounts of physical activity, specifically in sports activity. Furthermore, improvement of Fitness level resulted from raised PAL.
We thought that results of these studies are important to establish a standard for physical activity energy expenditure in Japanese adolescents.
