This means that glucose transport capacity was not a key determinant for glycogen accumulation under normal diet and the training situation; Ingestion of creatine or glutamine for 2 weeks prior glycogen depletion exercise exert no rule in glucose transport, GN gene expression, GS activity, and muscle glycogen resynthesis rate and amount during recovery from depletion exercise, but the interactions between endurance training and glutamine, high-intensity intermittent training and creatine, and endurance training and high-intensity intermittent training, were all capable of increasing muscle glycogen resynthesis significantly.
