Effects of Water-based Concurrent Resistance and Aerobic Training in Inactive Young Women

Abstract

PURPOSE: The aim was to investigate the effects of the intra-session exercise order in water-based concurrent training on peak oxygen uptake, isometric and concentric peak torques and maximal dynamic strength in young women. METHODS: Twenty-six women (25.1 ± 2.9 years) were placed into two groups: resistance before (RA) or after (AR) aerobic training. Subjects trained resistance (sets at maximal effort) and aerobic training (at heart rate in the anaerobic threshold) during 12 weeks (twice a week) performing both exercise types in the same training session. Bruce protocol was used to determine the peak oxygen uptake of the subjects. The isometric and concentric peak torques during knee flexion and elbow extension were measured with a Biodex dynamometer at 60°.s-1. Maximal dynamic strength was assessed using the 1 repetition maximal test (1RM) on the bilateral knee flexion and elbow extension. The training-related effects were assessed using a two-way ANOVA with repeated measures. RESULTS: The peak oxygen uptake showed significant increases after training (RA: 6.79 ± 7.40 vs. AR: 5.07 ± 4.32%, p<0.001) and both groups presented similar gains. After training, there were significant improvements on isometric peak torque during knee flexion (RA: 9.02 ± 4.87 vs. AR: 9.44 ± 8.19%, p<0.001) and on concentric peak torque during knee flexion (RA: 9.24 ± 10.39 vs. AR: 14.46 ± 9.86%, p<0.001) and elbow extension (RA: 6.99 ± 11.16 vs. AR: 2.74 ± 10.69%, p=0.042), with no difference between groups. Significant increases were found after training on bilateral knee flexion (RA: 27.14 ± 13.43 vs. AR: 23.93 ± 19.05%, p<0.001) and elbow extension 1RM (RA: 21.88 ± 11.70 vs. AR: 17.0 ± 17.73%, p<0.001), with no difference between groups. CONCLUSION: The intra-session exercise order in water-based concurrent training had no influence on the peak oxygen uptake, isometric and concentric peak torques and maximal dynamic strength in young women.
