AIM: 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.
CONCLUSION: although under simulated condition, karate combat poses large physiological stress to the karateka. However, physiological strain to karate combat led to a catabolic hormonal response.
