体育活动已被证明是一个有益的刺激中枢和外周神经系统。S100 B是一种主要由中枢神经系统（CNS）上的星形胶质细胞生理性产生和释放的细胞因子。为了研究非冲击性运动对血清S100 B水平的可能影响，我们在7,600米游泳比赛后测量了血清S100 B蛋白水平。我们观察到运动员比赛后S100 B水平与基线值相比有所增加，这表明体育锻炼对血清S100 B水平的潜在急性影响与CNS损伤无关。我们讨论了这一结果，并强调可能的中央和外周起源的S100 B血清水平。
Physical activity has been shown to be a beneficial stimulus to the central and peripheral nervous systems. The S100B is a cytokine physiologically produced and released predominantly by astrocytes on the central nervous system (CNS). In order to study the possible influence of a nonimpact exercise on S100B serum levels, we measured this protein serum level after a 7,600-meter swimming race. We observed an increase in S100B levels in athletes post-race compared with their baseline values, pointing to a potential acute influence of physical exercise on serum S100B levels not related with CNS injury. We discuss this result and emphasize the possible central and peripheral origins of S100B serum levels.
