volume analyzer was calibrated with a 3-L calibration pump. Muscle Activity Muscle activity was recorded using a wireless bipolar surface electromyography (EMG) system (eMotion Faros; Mega Electronics Ltd, Kuopio, Finland). Surface EMG is a valid measure for muscle activity. 31 The skin was shaved and
