Water Intake Associated With Aerobic Exercise in Coronary

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 cardiorespiratory parameters, cardiac autonomic modulation, and subjective perceptions of effort and pain of individuals with autonomic alterations known as the coronary arteries remain poorly understood. In this sense, this study intends to investigate the influence of hydration on cardiac autonomic modulation, cardiorespiratory parameters, subjective perception of exertion and pain of coronary arteries submitted to aerobic exercise in the model of a cardiovascular rehabilitation session. A total of 31 individuals will be recruited in this study and will perform four standardized cardiovascular rehabilitation sessions. Only in the second and the fourth session will the volunteers be instructed to ingest a quantity of water predetermined by the evaluator, based on the loss of body mass measured in the first and the third sessions. The outcomes (autonomic modulation, cardiorespiratory variables and perceptions) will be evaluated before, during and after exercise. The results of this study will enable professionals working with this population to implement awareness strategies on the importance of fluid intake in cardiovascular rehabilitation programs.

Conditions

Interventions

OTHER

Treadmill aerobic exercise in supine position

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.

OTHER

Treadmill aerobic exercise and water intake in supine position

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.

OTHER

Treadmill aerobic exercise in orthostatic position

The volunteers will be submitted to a cardiovascular rehabilitation session with 40 minutes of treadmill aerobic exercise followed by 10 minutes of recovery at the orthostatic position.
