Abstract
Introduction Maximal aerobic capacity (VO2max) is a stronger cardiovascular diseases indicator, mortality predictor and is related with other health factors (1). The aim of this study was to determine which training protocol is the most effective to improve the VO2max in overweight people. Methods Ninety overweight people, men and women (18 ? 50 years; BMI > 25 and < 30 kg/m2), participated in the study. Each subject performed two incremental tests, before and after intervention, until exhaustion to determinate VO2max on a treadmill, using a modified Bruce protocol (2). Subjects were randomized to one of the following training groups: strength training (ST; n = 22),aerobic training (AT; n = 25), a combination of AT and ST (COM; n = 23) (Training frequency: 3 times per week / Intervention: 24 weeks) and control group (CG; n = 20). All of them in combination with the same diet restriction. Two way ANOVA with repeated measures was used to determine differences between pre and post intervention in each training group. The significant level was set at ?0.05. Results Significant improvements in VO2max (mL/min) were obtained in all groups although the highest increases were in ST (Pre. 3180.6 ± 704.1 vs. Post. 3788 ± 509.5) and COM (Pre. 3277.2 ± 589.1 vs. Post. 3859.4 ± 430.2) in men. In women, we have obtained significant improvements in VO2max (mL/min) in all groups, except in ST. Aerobic training group obtained the highest increase in women (Pre. 2021.5 ± 263.3 vs. Post. 2367.1 ± 374.4). When we compare the results of VO2max related to body mass (mL/min/kg) significant improvements in all groups were obtained. Discussion In young women, Poehlman et al. (2002) obtained similar results to us because the strength group did not improve. Sillanpaa et al. (2009) obtained similar results with older women, all groups improved VO2max, except the ST group. Stensvold et al. (2010) obtained the highest improvements in aerobic and combined training groups, in contrast to our results, since we obtained improvements in ST in men too. We can conclude that aerobic training improves VO2max in women while in men the improvements are greater in strength training groups (ST and COM). References 1. Stensvold D, et al.
