  1. Significantly different from before Ramadan: * (P < 0.05); ** (P < 0.01); *** (P < 0.001). Note: FAST = subjects training in a fasted state; FED = subjects training in a fed state; a = inter-assay coefficient of variance. Before Ramadan (Bef-R) = 2 days before beginning the fast; end of Ramadan (End-R) = 29 days after beginning the fast.
