Water ingestion decreases cardiac workload time-dependent in healthy adults with no effect of gender

Abstract Ingestion of water entails a variety of cardiovascular responses. However, the precise effect remains elusive. We aimed to determine in healthy adults the effect of water on cardiac workload and to investigate potential gender differences. We pooled data from two controlled studies where bl...
