Introduction: Long-duration physical activity in winter is associated with significant demands for neurovegetative system. Aim: To explore the changes in the parameters of sympathetic and parasympathetic neurovegetative systems in men during a winter marathon. Methods: Parameters of the sympathetic and parasympathetic nervous systems of the group were estimated in 15 men after the winter marathon (50 km) using an automated computer-based system. Pairwise comparisons matrices of the parameter of the sympathetic and parasympathetic systems before and after the marathon were performed. There were found the k numbers of pair samples that had a common general population. Results: Four matrices of pairwise comparisons were constructed and shown the increasing of the proportion of stochastic from k1 = 11 to k2= 13 for the sympathetic autonomic nervous system. Conclusions: An equidirectional dynamic of stochastic's proportion changes before and after the marathon is observed. For the sympathetic and parasympathetic systems, the drop of chaos is observed, but we still can make a conclusion on the statistical instability of the samples. |
