Note. VO2max = maximal oxygen uptake (mL/kg/min); Sex, 0 = male, 1 = female; Accy. = accuracy instruction; Spd. = speed instruction; ERN = error-related negativity; P-E = post-error; PC = percentage correct (response accuracy); RT = response time.
All correlation coefficients ≥ .246 were significant at p ≤ .05.
