A Comparing of Body Composition Components in Physically Active and Inactive Male Students of Sharoud University of Technology

Introduction: Obesity is a serious health problem that reduces life expectancy by increasing one's risk of developing coronary artery disease, hypertension, type 2 diabetes, obstructive pulmonary disease, osteoarthritis and certain types of cancer. Moreover, body composition is divided into fat and fat free mass components. Research shows that physical activity is an important factor that affects body composition. This research aimed at estimating and comparing the body composition components of physically active and inactive male student of Shahroud University of technologyMethods: Participants of this study were 70 inactive male students with average age of (20.86±1.72) years and 65 physically active male students with average age of (20.86±1.72 years). The participants were randomly selected through stratified sampling procedure from various faculties and different admission years. Body composition was estimated with Body composition analyzer system that measured body composition components using bioelectrical impedance method.Results: Data analysis with SPSS-15 software revealed that: average of BF% in physically active sample was (13.43±3.15) and average of inactive samples was (16.73±6.16) which statistically showed significant difference (P<0.001) ; the LBM in physically active samples was (60.27±8.05 Kg) and average of inactive samples was (56.43±7.6 Kg) which statistically showed significant difference (P<0.005); the average of BMI in physically active sample was (22.62±2.8 kgm) and average of inactive samples was (22.25±3.84 kgm) which statistically did not show significant difference (P=0.519); the WHR average of physically active samples was (0.798±.03m) and average of inactive samples was (0.81±.06m) and there was not a significant difference between the two groups. Conclusion: These results revealed that body composition of physically active students were better than that of the inactive ones, so it can be concluded that there is a relationship between physical activity and the changes in the percent of body mass.
