A Comparison of the Pulmonary Function of Older Endurance Athletes with Age-Matched Sedentary Controls

Purpose: To compare the pulmonary function of older runners with non-runners and also the population norms. Method: 40 males ages 45 to 65 were compared for respiratory muscle strength, spirometry and maximum voluntary ventilation. Univariate and multivariate analysis (p < 0.05) were used to determine differences Results: No significant differences in age, height, or respiratory muscle strength were found. A significant difference was found for weight and BMI with the non-runners having greater values. The dependent variables of FVC, FEV1, FEF25-75%, PEF, and MVV resulted in a significant difference with the runners having greater values. A significant difference was also found for pulmonary function between runners and the general population. Conclusion: Continued and habitual aerobic exercise in the form of running in 45 to 65 year old men resulted in pulmonary function values that were significantly greater than those of the non-runners and also greater than population norms.
