Study of the relationship between a recreational sports program and an educational nutritional program accompanied by changes in body fat percentage among schooled adolescents (15-18 Years)

Aim. The study aims to examine the effectiveness of a recreational sports program coupled with nutritional education on the body fat percentage (BFP) among adolescent students. Material and method. The research was conducted on a sample of 16 male adolescents, aged between 15 and 18 years, enrolled at Hadi Mahmoud High School in Tamalouka District, Guelma Province. The researcher utilized an experimental method with a single-group design, employing a questionnaire developed by MARTIN in 2000 to assess the level of physical activity. A proposed recreational sports program was implemented over a duration of 10 weeks, with three sessions per week, accompanied by an educational program consisting of eight theoretical lessons. Results. The post-intervention results revealed a significant improvement in the level of physical activity, evidenced by the absence of any individuals with physical inactivity. The findings showed that 10 individuals, representing 62.5% of the sample, had a low level of physical activity, while six individuals, representing 37.5% of the sample, exhibited a moderate level of physical activity. No individuals were recorded with a high level of physical activity. Regarding the measurement of body fat percentage, a noticeable improvement was observed compared to the baseline results, with five individuals, representing 31.25% of the sample, having a high body fat percentage and 11 individuals, representing 68.75%, having a very high body fat percentage. The mean body fat percentage among the sample was recorded at 25.77%, with the lowest value noted at 20.3% and the highest at 30%. The post-intervention results also indicated that the Sig values were less than the significance level of 0.05, suggesting a statistically significant relationship between the level of physical activity and body fat percentage (BFP).
