Brief Summary:
Although approaches to reduce cardiovascular disease coronary artery disease CAD remains the leading cause of mortality in the industrialized world In order to reduce the deleterious effects of the atherosclerotic process proposals for non-pharmacological treatment have been used such as cardiac rehabilitation programs with emphasis on exercise -based therapy Traditionally aerobic exercises like biking walking and jogging are conducted however alternative ways such as aquatic exercise training have been proposed however the cardiorespiratory adaptations in this population are not well documented in the literature Thus the aim of this study was to evaluate the effects of aquatic aerobic training AAT on body composition autonomic modulation of heart rate HR and cardiorespiratory and metabolic variables in patients with CAD This was a longitudinal clinical trial with a sample allocated for convenience in which twenty-one patients were male with a diagnosis of CAD which were divided into control group CG were studied n8 who was only assessed and training group TG n13 All patients underwent assessment of body composition heart rate variability HRV at rest in the supine posture and cardiopulmonary exercise testing CPET performed before and after the AAT program The training protocol consisted of three sessions per week on alternate days for 16 weeks totaling 48 sessions which had lasted approximately one hour The exercise intensity was prescribed between 80 and 110 of the first ventilatory threshold VT1 obtained in CPET Given that these parameters represent risk markers for cardiovascular events in the population studied the results suggest that the AAT proposed in this study may be an important therapeutic strategy to be incorporated into cardiac rehabilitation programs
Detailed Description:
1 Personal Data recording
History personal data lifestyle and food family history current and previous history of disease
Physical examination cardiac and lung auscultationmeasurement of heart rate HR blood pressure BP body weight and height
2 Assessments
All experimental procedures were performed in the morning in order to minimize the influence of circadian cycle The temperature of the experimental room was maintained between 22 C and 24 C with relative humidity between 40 and 60 Patients were familiarized with the experimental protocol and instructed not to ingest stimulant drinks such as coffee tea and soft drinks do not drink alcohol do not perform strenuous exercise 48 hours before surgery and to perform a light meal at least four hours before the collections
Aiming to verify if the baseline conditions were suitable for the beginning of the experimental procedures the patients remained 15 minutes of rest in the supine position and recorded blood pressure BP and HR
After this were performed
Analysis of body composition by bioelectrical impedance analysis
Registration of HR and NN intervals NN during rest in the supine and sitting positions
Recording of HR and NN during rest in the supine position sitting standing and during respiratory sinus arrhythmia maneuver
Spirometric test and
Cardiopulmonary exercise test CPET This is a submaximal CPET performed on a treadmill in order to verify and identify possible changes in hemodynamic electrocardiographic induced to physical exertion their aerobic functional capacity as well as to prescribe physical training protocol
3 Training
After this assessment the volunteers were trained by a aerobic water based physical training program for 4 weeks
4 Second assessment
Components of the first assessment have been repeated at the end of each month of physical training
