Acute Effects of Water-Based Concurrent Training Intrasession Exercise Sequences on Energy Expenditure in Young Women.

Abstract

To compare the acute effects of water-based aerobic-resistance and resistance-aerobic concurrent training (CT) sessions on energy expenditure (EE) during and postexercise in young women. Nine active women (24 [3]y; 60 [5]kg) completed 4 sessions: (1)familiarization, (2)aquatic maximal test to determine the heart rate corresponding to the anaerobic threshold, (3)CT protocol with aerobic-resistance sequence, and (4)CT protocol with resistance-aerobic sequence. Both protocols started and ended with the participants in the supine position for 30minutes to perform resting and postexercise oxygen consumption measurements. The water-based resistance protocol comprised 4 sets of 15 seconds at maximal velocity, and the water-based aerobic protocol was performed at a continuous intensity (heart rate corresponding to the anaerobic threshold). EE measurements were calculated based on oxygen consumption and the corresponding caloric equivalent. Paired t test was used to compare the EE values between the water-based CT intrasession exercise sequences (α = .05). There was no difference between the water-based aerobic-resistance and resistance-aerobic in total EE (330.78 vs 329.56kcal; P = .96), EE per minute (7.35 vs 7.32kcal·min-1; P = .96), and postexercise EE (63.65 vs 59.92kcal; P = .50). The intrasession exercise sequence during water-based CT had no influence on the EE in young women.
