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.
本研究旨在探讨运动对久坐女性和女性职业篮球运动员静息能量消耗和自主神经系统适应性的影响。在为期六个月的时间里，分别测量了静息能量消耗、身体成分和自主神经系统的活动水平。研究发现，体育活动可增加静息能量消耗和游离脂肪量，而不影响体重。心率变异性的功率谱分析表明，篮球运动员的副交感神经活动显著增加。这些发现表明，运动员的静息能量消耗高于久坐女性，尽管副交感神经活动增强通常与较低的能量消耗有关。
