Abstract

BACKGROUND

This study aimed to evaluate the relationship between physiological, and parameters of performance analysis during karate contest.

METHODS

Nine elite-level karate athletes participated in this study. Saliva sample was collected pre- and post-karate combat.

RESULTS

Salivary cortisol (sC) post-combat 2 raised significantly compared to that recorded at pre-combat 1 (Δ%=105.3%; P=0.04; dz=0.78). The largest decrease of the salivary T/C ratio (sR) compared to pre-combat 1 was recorded post-combat 2 (Δ%=-43.5%; P=0.03). Moreover, blood lactate concentration post-combat 1 correlated positively to sCpost-combat 1 (r=0.66; P=0.05) and negatively to both salivary testosterone (sT) (r=-0.76; P=0.01) and sRpost-combat 1 (r=-0.76; P=0.01). There was no significant relationship between hormonal measures and parameters of match analysis.

CONCLUSIONS

Although under simulated condition, karate combat poses large physiological stress to the karateka. Additionally, physiological strain to karate combat led to a catabolic hormonal response.

摘要

背景

本研究旨在评估空手道比赛期间生理指标与表现分析参数之间的关系。

方法

九名精英级空手道运动员参与了本研究。在空手道比赛前后采集唾液样本。

结果

与比赛前1（Δ%=105.3%；P=0.04；dz=0.78）相比，比赛后2唾液皮质醇（sC）显著升高。与比赛前1相比，比赛后2唾液T/C比值（sR）下降幅度最大（Δ%=-43.5%；P=0.03）。此外，比赛后1血乳酸浓度与比赛后1 sC呈正相关（r=0.66；P=0.05），与唾液睾酮（sT）（r=-0.76；P=0.01）和比赛后1 sR均呈负相关（r=-0.76；P=0.01）。激素指标与比赛分析参数之间无显著关系。
