Cardiovascular diseases (CVD) represent the most frequent cause of death among the elderly population. Hypertension, unfavorable lipid profile, obesity and physical inactivity are among the main risk factors for CVD. In contrast, mortality from CVD is inversely related to levels of physical activity, and is lower in individuals who exercise and have higher functional fitness levels. Thus, the Centers for Disease Control and Prevention, the American College of Sports Medicine, and the American Heart Association have recommended 20-30 min of moderate-to-vigorous aerobic training for the elderly, preferably every day or at least 3 days a week in the case of vigorous exercise.The same organizations also suggest the inclusion of resistance training in order to improve functional fitness. Therefore, the purpose of this study was to compare different exercise modalities in long-term changes of CVD risk factors and physical fitness among older adults.

Further study details as provided by University of Trás-os-Montes and Alto Douro:

Primary Outcome Measures:
  • Cardiovascular disease risk factors [ Time Frame: one year ] [ Designated as safety issue: Yes ]

    Bioelectrical impedance analysis to measure body fat percentage (%), fat-free mass (k) and dry lean mass (Kg).

    Electronic sphygmomanometer to measure systolic blood pressure (mmHg) and diastolic blood pressure (mmHg).

    Peripheral blood samples to collect serum lipid triglycerides (mg/dL), total cholesterol (mg/dL), low-density lipoprotein cholesterol (mg/dL) and high-density lipoprotein cholesterol (mg/dL), and analyzed by enzymatic techniques.

Secondary Outcome Measures:
  • Physical fitness [ Time Frame: One year ] [ Designated as safety issue: No ]

    Functional fitness was assessed according to the Fullerton Functional Fitness Test, and included 6 independent tests: 30-s chair stand (repetitions), arm curl (repetitions), chair sit-and-reach (cm), back scratch (cm), 8-foot up-and-go (s) and 6-min walk (m).

    Falls risk was measured by the timed up-and-go test (seconds) and the functional reach test (cm).

Other Outcome Measures:
  • Quality of life [ Time Frame: One year ] [ Designated as safety issue: No ]
    Measured by the Satisfaction With Life Scale.
