- Abstract
The aim of this study is to make an attempt to determine an extension of exercise intensity and energy expenditure during the whole day of physical activity of youths from gymnasium, coming into the period of pubertal maturation. Differences between the extension of exercise loads, undertaken during the fall-winter and spring-summer periods, are also determined. Studies were carried out in 10 boys and 10 girls by the registration of their physical activity twice during 24 h -- in the fall-winter and the spring-summer periods, in common days of the week. The registration of exercise loads was realized by the Sport-Testers of Polar Company, model S 610i. Comparing the level of physical activity in the fall-winter and spring-summer periods in the 13-year-old girls, it was observed that there was an increase of the time of the duration of exercises undertaken above 140 bpm (50% of HRR). During 24 hours only 6-7% of time (about 90 minutes) for boys, and even less -- only 4-6% (about 60-90 minutes) for girls was set off for exercises of load stimulating functions of oxygen supply, that is at the level above 140 bpm (above 50% of HRR). A characteristic phenomenon was an observed relation between energy expenditure at the level above 3000 kcal in winter and summer, while on average it was amounted to a half less during 24 hours. Hence, comparing intensity load scopes in these two examined periods a decreased level of physical activity in the fall-winter period was observed among both the examined girls and boys.
