denotes p < 0.05 between before and after RMET. denotes p < 0.05 between the RMET group and controls.V: maximal minute ventilation during the respiratory endurance test; V: maximal tidal volume during the respiratory endurance test; f: maximal breathing frequency during the respiratory endurance test; DLa: delta lactate concentration (i.e., lactate concentration measured 3 min after the end of trials minus lactate concentration at rest).
