The purpose was three-fold: (1) to investigate the effect of baseline, precompetition, and postcompetition stress on salivary cortisol levels in top-ranking Brazilian wrestlers (N = 17) participating in a national competition; (2) to estimate correlations among three stress measures (perceived stress, salivary cortisol, and physiological stress reaction); and (3) to compare cortisol concentrations between losers and winners. Salivary cortisol was collected at baseline, pre-, and postcompetition. Physiological stress reaction and perceived stress scores were measured just before warm-up for the competition. Analysis showed a significant main effect for testing time. Correlations among the stress measures were not significant. Analysis of covariance between the winners (n = 10) and the losers (n = 7) was also not significant. Salivary cortisol concentrations increased after the intense exercise of competition. The wrestlers did not perceive any physiological effects.
(1)调查在全国性比赛中处于顶尖水平的巴西摔跤手(N=17)的基线、赛前和赛后压力对唾液皮质醇水平的影响;(2)评估三种压力测量(感知压力、唾液皮质醇和生理应激反应)之间的相关性;(3)比较输家和赢家的皮质醇浓度。在基线、赛前和赛后采集唾液皮质醇。在比赛热身前测量生理应激反应和感知压力得分。分析显示测试时间存在显著的主效应。压力测量之间的相关性不显著。对获胜者(n=10)和输家(n=7)的协方差分析也不显著。唾液皮质醇浓度在激烈的比赛运动后增加。摔跤手没有感觉到任何生理影响。
