Vitamin E and aerobic exercise: effects on physical performance in older adults

Background and aims : Aerobic endurance exercise enhances antioxidant defenses and improves the physical performance of older adults. However, the combined effect on physical performance of exercise and an antioxidant such as vitamin E has not been investigated. The purpose of this study was to evaluate the effects of six months of vitamin E supplementation and supervised aerobic training on physical performance and body composition in sedentary older adults. Methods : Fifty-seven adults, whose average age was 71.5±7.5 years, were randomly assigned to an exercise (E), exercise-vitamin (EV), control (C) or vitamin (V) group, and were evaluated before, halfway through, and after training. The dose of vitamin E was 900 IU/day. The training program comprised three sessions of walking exercise per week, at an intensity of 70% of heart rate reserve. Results : In the E and EV groups, the training program significantly reduced (p
