OBJECTIVES: To assess the ability of sedentary, frail subjects aged 80 and older to train in a community-based exercise program and to evaluate clinical factors that predict improvements in peak oxygen consumption (VO2 peak). DESIGN: Pretest, posttest. SETTING: Charlestown Retirement Community, Catonsville, Maryland PARTICIPANTS: Twenty-two (11 male, 11 female; mean age ± standard deviation = 84 ± 4.0, range 80–92) self-referred. INTERVENTION: Six months of moderate-intensity aerobic exercise training, two to three sessions/week, 20 to 30 minutes per session. Training modes included treadmill walking and/or stationary cycling. MEASUREMENTS: Baseline and follow-up maximal exercise treadmill tests (ETTs) with electrocardiogram monitoring and respiratory gas analysis. RESULTS: Six months of aerobic exercise training resulted in significant increases (mean ± standard deviation) in ETT duration (11.9 ± 3.3 vs 15.9 ± 4.3 minutes; P = .01), VO2 peak (1.23 ± 0.37 vs 1.31 ± 0.36 L/min; P = .04), and oxygen pulse (9.3 ± 2.8 vs 10.1 ± 3.2; P = .03). Mean heart rate was significantly lower during submaximal ETT stages 1 through 4 (P < .05), and resting systolic blood pressure decreased (146 ± 18 vs 133 ± 14 mmHg; P = .01) after training. Multiple regression analysis indicated that baseline VO2 peak (r = 0.75, P = .002) and the total amount of time spent in exercise training (r = 0.55, P = .008) were independent predictors of the training-related improvements in VO2 peak. CONCLUSION: Subjects aged 80 and older can increase aerobic capacity and reduce systolic blood pressure in a community-based exercise program of moderate intensity. The most important predictors of change in VO2 peak were baseline VO2 peak and the time spent in exercise training. Subjects with a lower baseline VO2 peak had the greatest improvements in VO2 peak... [ABSTRACT FROM AUTHOR] |
