The relationships among endurance performance measures as estimated from VO2PEAK ventilatory threshold and electromyographic fatigue threshold: a relationship design

摘要

BackgroundThe use of surface electromyography has been accepted as a valid, non-invasive measure of neuromuscular fatigue. In particular, the electromyographic fatigue threshold test (EMGFT) is a reliable submaximal tool to identify the onset of fatigue. This study examined the metabolic relationship between VO2PEAK, ventilatory threshold (VT), and the EMGFT, as well as compared the power output at VO2PEAK, VT, and EMGFT.
