Abstract

The resting energy expenditure and the adaptation of the autonomic nervous system induced by sport activities in sedentary women and in female professional basketball players have been studied. Resting energy expenditure, body composition and the level of activity of the autonomic nervous system were measured before and after a period of six months. The physical activity induced an increase in resting energy expenditure and free fat mass without variations in body weight. Basketball players showed a significant increase in the parasympathetic activity, measured by the power spectral analysis of the heart rate variability. These findings demonstrate that resting energy expenditure is higher in the athletes than in sedentary women, despite the augmented parasympathetic activity that is usually related to lower energy expenditure.

Abstract

The aim of this study was to test the effects of age and chronic exercise training on antioxidant and heat shock protein (Hsp) expression by comparing the hearts of young (Y), sedentary old (SO) and trained old (TO) rats. In SO rats, there were: (a) changes in myocardial structure and function; (b) increased malondialdehyde levels; (c) no changes in superoxide-dismutase (SOD) enzymes; (d) reduced Hsp70 expression; and (e) increased Hsp27 expression. In TO rats, SOD enzymes and Hsp70 expression were increased and Hsp27 was further increased. Malondialdehyde level did not differ between TO and SO rats, which shows that chronic exercise did not affect the peroxidation index. In summary, by increasing Hsp27 and Hs70 levels, prolonged exercise partially counterbalanced the heart age-related effects in the antioxidant system without altering peroxidation levels. These findings suggest that the beneficial effects on aged-related cardiovascular changes could be connected to the "anti-oxidant" effects of prolonged exercise training.
