Association between physical activity and body composition of high school students
Abstract
The purpose of this study was to determine the effect of physical activity on the body composition of adolescents. The study sample consisted of 735 students (299 boys: mean age 17.20 years; 436 girls: mean age 17.16 years). Physical activity levels were determined using the long version of International Physical Activity Questionnaire (IPAQ). Questionnaires were administered online within teaching using INDARES system. Body composition was measured using body composition analyzer InBody 230. The parameters examined were: body mass index (BMI), body fat mass index (BFMI), fat free mass index (FFMI), percent fat mass (FM%), visceral fat area (VFA) and waist-hip ratio (WHR). For determining statistically significant differences between more physically active and less physically active (S0) girls and boys was used t-test for independent samples. Average results of body composition were more favorable in students who failed to meet physical activity guidelines. These differences were statistically significant for boys in BFMI (p 0.049), FM% (p 0.038), WHR (0.026) and for girls in BMI (0.021) and FFMI (p 0.004). The results of the present study did not confirm positive effect of physical activity on the parameters of health investigated.
