Examination Of Physiological And Perceptual Responses During Sustained, Isometric, Fatiguing, Handgrip Exercise Anchored To Ratings Of Perceived Exertion, Minyoung Kwak
Theses and Dissertations--Kinesiology and Health Promotion
The purposes of this study were to: 1) Examine the patterns of force responses relative to critical force (CF) during submaximal, fatiguing, isometric handgrip exercise anchored to different rating of perceived exertion (RPE) levels (RPE=3, 5, and 7); 2) assess the loss of force during the task and the level of performance fatigability after each RPE hold; 3) examine the time course of changes and patterns of neuromuscular [electromyography (EMG) amplitude (AMP), mean power frequency (MPF), mechanomyography (MMG) AMP and MPF, and neuromuscular efficiency (NME) (i.e. force/EMG AMP)] and muscle oxygen saturation (% SmO2) responses during each RPE …
