Abstract:

 

The aim of this experimental research is to determine the impact of the additional session of physical and sports activities in school on the percentage of body fat and some physiological parameters in adolescent boys 16 - 18 years old . A sample of 71 students schooling in hight school have accepted to follow our research program for (10) weeks after being informed and received written consent. The control sample practice one physical and sporting activity session per week, the experimental sample practice two sessions per week. They were divided into two groups by the random method. We evaluated the percentage of body fat by the slaughter equation, the relative vo2max by the 20m shuttle test of (luc leger), the alactical anaerobic power by the Sargent test and the recovery capacity by the Ruffier Index .The results obtained show that the percentage of body fat to be increased in both samples and to a lesser degree in the experimental sample .There was a significant increase in relative vo2max in the experimental sample with relative stability in the control sample. A significant increase in anaerobic alactic power was observed in both samples with a greater degree in the experimental sample. Regarding the recovery capacity , there was a significant improvement in the level of the experimental group. There is an inverse relationship between the percentage of body fat and some physiological variable under study
