About this study
Official title: Effect of Different Hydration Strategies on Autonomic Acceleration During Recovery in Individuals With Coronary Artery Disease Undergoing Aerobic Exercise
The need to restore water losses resulting from physical activity has become established and diffused into international consensus for healthy individuals or high-performance athletes. However, the influence of fluid replacement when administered during and after exercise on cardiac autonomic modulation with autonomic alterations known as the coronary arteries remain poorly understood. The aim of the study was to evaluate and compare whether different hydration strategies are able to promote acceleration of the recovery of autonomic modulation in individuals with coronary artery disease undergoing aerobic exercise. This study is a cross-over clinical trial, which will be developed based on an experimental procedure performed in four stages. A total of 31 individuals will be recruited in this study and will perform four standardized cardiovascular rehabilitation (CR) sessions. The participants will perform CR with mineral water intake in phase three and four. In phase three, the consumption will be done a quantity of water predetermined by the evaluator, based on the loss of body mass measured in the second session. In phase four, hydration will be carried out in an uncontrolled manner, according to the desire to drink water during the protocol.
