Effect of a combined training in aerobic fitness and body composition in adults
Abstract
The aim of this study was to investigate the effect of a combined training (aerobic + resistance) in aerobic fitness and body composition in adults. Thirteen individuals, seven males (30.9 ± 4.6 years, 174 ± 7 cm height) and six females (32.2 ± 6.4 years, 162 ± 7 cm), underwenta combined training for 12 weeks with a frequency of three times per week, with sessions of 55 min, consisting of 25 min of aerobic exercise intensity on the point of deflection of heart rate (PDHR) and 30 min of resistance exercise with weights. Were evaluated indicators of body composition (% fat and lean mass, body mass index (BMI) and waist hip ratio (WHR) and aerobic aptitude (peak velocity -PV, maximal oxygen uptake -VO2MAXand running speed corresponding to the PDHR -VDMAX) before and after training. Descriptive statistics and paired t-test were used for data analysis, with a significance level of p <0.05. There was significant increase for aerobic aptitude indicators (VO2MAX, PV, VDMAX), and % lean mass, whereas body mass, % fat, BMI and WHR decreased after training, for both sexes. It follows that 12 weeks of combined training can cause changes in the aerobic aptitude and body composition in both sexes.
