Abbreviations BCAA-CHO branched-chain amino acid and carbohydrate-supplemented group, CHO carbohydrate only-supplemented group
Analysis of monocyte percentages revealed a group*time interaction (p = 0.01) whereby BCAA-CHO supplementation attenuated increases in monocyte percentages 24 h following bout 1 (p = 0.049), 24 h following bout 2 (p < 0.001), and 48 h following bout 3 (or at T2; p < 0.001) compared to CHO supplementation (denoted by bold lettering and superscript ‡ symbol). Moreover, T2 monocyte percentages increased within the CHO group at T2 compared to T1 (denoted by superscript † symbol, p = 0.012)
