Key result
Ingestion of 500 ml of water immediately after upper-body resistance exercise increased cardiac vagal index at 30 minutes compared to 50 ml (1.39 vs. 1.23; p=0.02).

Does 500 ml water intake improve cardiac vagal reactivation in healthy men after upper-body resistance exercise?
Absolute Event Rate: 1.39% vs 1.23%
p-value: p=0.02
Ingesting 500 ml of water immediately after upper-body resistance exercise accelerates cardiac vagal reactivation compared to 50 ml, potentially enhancing cardiovascular safety.
Teixeira et al. (2014) conducted an RCT in Healthy (n=13). Water intake vs. 50 ml of water was evaluated on Cardiac vagal index (CVI) 30 min post-exercise (p=0.02). Ingestion of 500 ml of water immediately after upper-body resistance exercise increased cardiac vagal index at 30 minutes compared to 50 ml (1.39 vs. 1.23; p=0.02).
