Fatigue plays a major role in limiting work performance. The objectives of this study were: (1) to determine the effect of wearing a work glove on handgrip fatigue; (2) to compare the effect of a sustained grip contraction of concentric versus eccentric nature, named in this study isometric and eccentric; and (3) to determine if there is a relationship between physiological muscle performance and subjective perceptional fatigue during isometric and eccentric gripping. The study had 2 ×2 repeated measures design. The two factors were: (1) glove condition (glove, no glove); and (2) type of contraction (eccentric and isometric). The measurements taken were: (1) time to limit of endurance (T _lim); (2) rate of perceived effort (RPE); (3) mean power frequency (MPF) derived from the electromyogram (EMG); and (4) the fatigue objective-subjective relationship (FOSR, which is the correlation coefficient between RPE and …
