Superscripts denote significantly differences among the periods. * p < 0.05, # p < 0.01, † p < 0.001. NOx = nitric oxide; GLU = glucose; HR = heart rate; GLU= resting glucose level; NO= resting nitric oxide level; LA= lactate; LAresting lactate level; PT = simulate the tennis performance test; Accuracy = percentage of the balls hitting the target.
