Premotor reaction time in movement A (a), movement B (b), movement C (c), and primary task in movement D (d), and reaction time in the secondary task in movement D (e) in the taekwondo- specific reaction test battery after each simulated matches in the AA and PL trialsa. aAA: BCAA, arginine, and citrulline; PL: placebo. (a) Main effects: trial: p = .156;time: p = .001; interaction: p = .016; (b) Main effects: trial: p = .541;time: p = .019; interaction: p = .025; (c) Main effects: trial: p = .872;time: p = .037; interaction: p = .038; (d) Main effects: trial: p = .113; time: p = .152; interaction: p = .015; (e) Main effects: trial: p = .123; time: p = .036; interaction: p = .018; * p < .05, ** p < .01, *** p < .001, significantly different between the 2 trials. #Significantly different from the baseline in the PL trial (p < .05)
