Pearson (r) correlation between Age, ΔCognitive Anxiety score (ΔCA), ΔSomatic Anxiety score (ΔSA), ΔSelf Confidence score (ΔSelf-C) and salivary hormonal markers in healthy soccer male athletes. The psychometric assessment and biological evaluations were performed at 96 and 24 h pre-official match (N = 56). OT = Oxytocin; C = Cortisol.

Δvariable = variable_{96 h} minus variable_{24 h}; *p < 0.05; **p < 0.01.
