Effect of the rest interval duration between contractions on muscle fatigue

Abstract: BackgroundWe aimed to investigate the effect of rest interval, between successive contractions, on muscular fatigue.MethodsEighteen subjects performed elbow flexion and extension (30 repetitions) on an isokinetic dynamometer with 80º of range of motion. The flexion velocity was 120º/s, while for elbow extension we used 5 different velocities (30, 75, 120, 240, 360º/s), producing 5 different rest intervals (2.89, 1.28, 0.85, 0.57 and 0.54 s).ResultsWe observed that when the rest interval was 2.89 s there was a … Show more

“…It is well documented in the literature 25 , 26 that short intervals during the recovery phase also contribute to greater residual fatigue between stimuli. This effect is associated both with PCr and ATP concentrations, which stimulate glycolytic metabolism during this type of activity, thereby increasing blood lactate levels 27 .…”

“…Moreover, the rest interval between trials ranged from 10 seconds to two minutes. Although rest time has not been commonly reported, it is important to reduce fatigue during strength tests (39,59). According to Nogueira et al (59), adequate rest intervals can reverse the fatigue mechanism and provide time for energy recovery of the assessed muscular group.…”

“…Accordingly, the most appropriate body position and work conditions to perform a specific task must be recognized. In this regard, some researchers have examined the relationship between work cycles (Iridiastadi & Nussbaum, 2006a; Rashedi & Nussbaum, 2016) and rest periods (Adamo et al, 2009; Mirhaji & Salmanzadeh, 2021; Nogueira et al, 2012; Shin & Kim, 2007) on muscle fatigue. The results show the significant effect of these two parameters on muscle fatigue.…”
