Effect of Acu-Transcutaneous Electrical Nerve Stimulation (Acu-TENS) on Post-exercise Expiratory Flow Volume in Healthy Subjects

This study aims to investigate the effect of Acu-TENS on forced expiratory volume in one second (FEV1), a test of pulmonary function used to assess airway resistance, during sub-maximal treadmill exercise in healthy subjects.
