Abstract：
:The aim of this study was to assess the hypothesis that water intake will accelerate cardiac vagal reactivation after a single session of upper-body resistance exercise. 13 healthy men (26.5±5.9 years) with previous experience in resistance training were enrolled. In visits 1 and 2, participants performed the one-repetition maximum (1RM) test and retest with the bench press exercise. The sessions 3 and 4 were performed randomly, while participants consumed 500 ml (experimental visit) or 50 ml (control visit) of water immediately after 3 sets of maximum repetitions at 80% of 1RM. Cardiac vagal activity was represented by cardiac vagal index (CVI) measured before, immediately after and 30 min post-exercise. Additionally, heart rate and blood pressure were measured. The results show that CVI was higher 30 min post-exercise when 500 ml of water was ingested compared to 50 ml (1.39±0.07 vs. 1.23±0.07; p=0.02) (mean±SEM). Heart rate and blood pressure values were similar in both trials. We conclude that water intake accelerates post-resistance exercise cardiac vagal reactivation. These findings suggest that hydration after resistance exercise might be beneficial for cardiovascular safety in healthy subjects.
