Elite athletes are thought to enter competition in a finely tuned psychophysiological state, but evidence from truly consequential settings is limited. We assessed ECG-derived cardiac autonomic activity and salivary steroid hormones during an elite snowboard Big Air competition conducted under international rules with prize money. Twenty-two male top-level athletes completed three jumps in official practice and three in the final. Before final jumps, athletes showed a marked shift toward sympathetic dominance relative to practice, with higher mean heart rate, lower RMSSD and lnHF, and higher LF/HF. Saliva assays of testosterone (T) and cortisol (C) showed that, during the second final jump, larger increases in log(T/C) were associated with better rank. This jump is especially pivotal because it can either consolidate a strong first run or intensify pressure after an unsuccessful one. These findings suggest that elite performance under extreme pressure may involve physiological readiness for action alongside a more approach-oriented endocrine profile. |
