Examination the Effects of Aerobic and Resistance Exercise on Body Compositions of Sedentary Male Individuals

Abstract

The present study was conducted to determine the effects of 8-week aerobic and resistance training on body composition values of sedentary male individuals. A total of 30 healthy sedentary male subjects volunteered to participate in the study and were divided into two groups randomly: aerobic training group (n = 15, age = 34.0 ± 5.22 years), and resistance training group (n = 15, age = 34.2 ± 6.12). Body heights of the participants were measured and their body compositions body weight (BW), body mass index (BMI), basal metabolic rate (BMR), body fat percentage (BFP), body fat mass (BFM), lean body mass (LBM) were measured with bioelectric impedance analysis (BIA) device, and then evaluated. Their resting heart rates were determined, and maximum heart rates were calculated with the Karvonen formula. The Brzycki Equation was used to predict one-repetition maximum strength. There were statistically significant decreases in BW, BMI, BFP and BFM values of the aerobic training group (p<0.05). There was no significant difference between pre- and post-test values of BMR and LBM (p>0.05). BW and BMI values of the resistance training group did not show a significant difference in pre-test and post-test (p>0.05). Significant decreases were found in BFP and BFM values (p<0.05). The increase in BMR and LBM values were found to be statistically significant (p<0.05). There were significant differences between BW, BMI, BMR, BFM and LBM values in the comparison of pre- and post-test values of the aerobic and resistance training groups (p<0.05). However, there was no statistically significant difference in BFP (p>0.05). In conclusion, it was found out that regular aerobic and resistance training caused positive effects on body composition of sedentary male individuals.
