Abstract
Whereas aging and pollution increase oxidative stress, aerobic exercise improves antioxidative capacity. But the effect of the type of exercise in relation to age is unclear. The purpose of the present study is to assess the effects of chronic training and an acute exhaustive incremental exercise on blood oxidative and antioxidative parameters in middle aged and older men, and to search the relations between these effects and age. Volunteers (n=54) consisted of two groups aged 40-60 years, and 65 years and above, with nine-subject-subgroups of sprinters, long distance runners and sedentary controls, respectively. Blood samples were collected at rest and following the exhaustive exercise. Blood superoxide dismutase (SOD), catalase (CAT), paraoxonase (PON1) activities and malondialdehyde (MDA) levels were determined as oxidative and antioxidative parameters. No significantly different results were obtained for these parameters with respect to training type and exhaustive exercise in each age group (p>0.05). No significant relationship between age and the basal parameter levels were present, either. These results suggest that the effects of both aerobic and anaerobic training on oxidative and antioxidative defense are independent of age and training type. Responses to acute exercise were similar to those of chronic training.
