Brief Summary

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.

Study Arms (3)

Control group

ACTIVE COMPARATOR

Only treadmill aerobic exercise with 60 min recovery in supine position.

Other: Treadmill aerobic exercise without water intake

Controlled hydration group

EXPERIMENTAL

Treadmill aerobic exercise with 60 min recovery in supine position, with mineral water predetermined intake.

Other: Treadmill aerobic exercise with water intake of a predetermined amount.

Ad Libitum hydration group

EXPERIMENTAL

Treadmill aerobic exercise with 60 min recovery in supine position, with mineral water intake in an uncontrolled manner.

Other: Treadmill aerobic exercise with water intake according to the desire to drink

Interventions

The volunteers will be submitted to a cardiovascular rehabilitation session with 40 minutes of treadmill aerobic exercise followed by 60 minutes of recovery at the supine position.

Control group

The volunteers will be submitted to a cardiovascular rehabilitation session with 40 minutes of treadmill aerobic exercise and water intake followed by 60 minutes of recovery at the supine position.

Controlled hydration group

The volunteers will be submitted to a cardiovascular rehabilitation session with 40 minutes of treadmill aerobic exercise and water intake followed by 60 minutes of recovery at the supine position.
