Key result
Hydration during a moderate-intensity cardiovascular rehabilitation session did not significantly improve vagal reactivation or autonomic modulation recovery compared to a control protocol without hydration in male patients with coronary artery disease.
Why the study?
Delayed autonomic recovery poses risks for coronary artery disease patients, motivating investigation into the influence of hydration on autonomic responses during immediate post-exercise recovery.
Population
28 males with coronary artery disease
Comparison
Hydration protocol with rehydration during exercise vs control protocol
Design
Crossover clinical trial

May accelerate vagal recovery post-rehab in CAD; leaves open whether routine hydration improves outcomes.
Effect estimate: η2P = 0.003
p-value: p=0.671
Laurino et al. (2021) studied Coronary artery disease (n=28). Hydration protocol vs. Control protocol (no hydration during exercise) was evaluated on Vagal reactivation evaluated through heart rate variability (RMSSD30) during the immediate recovery period (η2P = 0.003, p=0.671). Hydration during a moderate-intensity cardiovascular rehabilitation session did not significantly improve vagal reactivation or autonomic modulation recovery compared to a control protocol without hydration in male patients with coronary artery disease.
