Abstract
BackgroundIn our series of investigations concerning the causes of seasonal change in fat accumulation in young university students, we could not find any contribution of seasonal variation in the ratio of carbohydrate and fat metabolism to that of body fat percentage in Japanese and Thai participants. After our previous study, we examined the effect of daily physical activity on body fat percentage to look for the major causes of seasonal change in fat accumulation in young university students.FindingsIn this study, we measured participants’ (young Japanese and Thai university students) daily physical activity by a uniaxial accelerometer in addition to the measurements of body fat percentage and body mass index by a bioelectrical impedance meter. We found that there was significant and moderate negative correlation between body fat percentage and daily step counts among Japanese but not Thai participants. We observed significant, moderate and positive correlations between the percentage of body fat and body mass index among Japanese and Thai participants.ConclusionsDaily physical activity plays an important role in the seasonal variation of body fat percentage of Japanese female students. Our present study also confirmed the importance of daily physical activity for controlling body mass index and for the prevention of obesity.

Summary
In our series of investigations concerning the causes of seasonal change in fat accumulation in young university students, we could not find any contribution of seasonal variation in the ratio of carbohydrate and fat metabolism to that of body fat percentage in Japanese and Thai participants. We examined the effect of daily physical activity on body fat percentage to look for the major causes of seasonal change in fat accumulation in young university students. During the course of our investigation in this regard, we researched the causes of seasonal change in body fat percentage and body mass index on the assumption that seasonal changes in the balance of carbohydrate and fat metabolism is an intrinsic physiological mechanism for the seasonality of body fat percentage [2]. We could activity on the seasonal change in the body fat percentage and body mass index of Japanese and Thai female university students
