Key result
Drinking 500 ml of water before exercise elicited an overall decrease in submaximal heart rate compared with 50 ml of water (P < 0.05).
Why the study?
Does ingestion of 500 ml of water reduce the chronotropic response to dynamic exercise in healthy adults?
RCT (n=19)
randomized

p-value: p=< 0.05
Drinking 500 ml of water before exercise attenuates the chronotropic response to submaximal exercise, suggesting it should be recognized as a potential confounder in cardiovascular exercise studies.

500 ml water before exercise attenuates submaximal heart rate; should be standardized as a confounder in cardiovascular exercise trials.
Mendonça et al. (2013) conducted an RCT in Healthy adults (n=19). Water ingestion vs. 50 ml of water was evaluated on Submaximal heart rate (p=< 0.05). Drinking 500 ml of water before exercise elicited an overall decrease in submaximal heart rate compared with 50 ml of water (P < 0.05).
