“…Although W/R schedule did not significantly influence muscle fatigue overall, participants seemed to experience less fatigued in the forearm and upper arm muscles in the Long-break and Self-selected conditions (see Tables A1, A3, and A5). This outcome contradicts some previous studies, in which participants exhibited less fatigue (or better recovery) with more frequent task rotation or a short W/R cycle (Horton et al, 2012;Lin et al, 2012;Rashedi & Nussbaum, 2016;Wawrow et al, 2011). RPDs here also demonstrated a similar tendency, in that participants reported the least fatigue in some body regions in a Long-break condition, and moderate fatigue in a Self-selected condition.…”

“…Based on existing evidence, we anticipated that the use of short and frequent work breaks would lead to less fatigue or enhanced recovery compared with long and infrequent work breaks (Lin et al, 2012;Rashedi & Nussbaum, 2016;Wawrow et al, 2011). We also expected that a selfselected schedule would be preferred by the participants, due to the higher level of control it provided (Luger et al, 2016;Stålhammar et al, 1992).…”

The pattern of work and rest can influence both physical fatigue and task performance in manual operations. However, there is relatively limited evidence regarding the influences of specific work/rest schedules in tasks requiring high repetitiveness and precision demands, along with relatively low exertion levels. Eighteen participants completed an exploratory study that simulated such tasks, to compare the effects of three distinct work/rest schedules (i.e., short frequent [short] and long infrequent breaks [long], and a self-selected schedule) on muscle fatigue, task performance (in terms of accuracy and speed), and preference. Schedules with long or self-selected breaks generally induced less muscle fatigue, compared with the short break condition. Participants preferred the self-selected condition the most and the long-break condition the least. The different schedules tested did not influence task performance. A selfselected schedule may be beneficial for repetitive precision task, to achieve a balance across muscle fatigue, task performance, and individual preference.

“…Muscle fatigue has been examined using M-wave characteristics for compound muscle action potentials in previous studies (Milner-Brown & Miller, 1986;Fuglevand et al, 1993;Rabischong et al, 1995;Botter et al, 2009;Wawrow et al, 2011;Walker et al, 2013). M-wave duration is especially related to the conduction velocity of the muscle action potential (Milner-Brown & Miller, 1986;Wawrow et al, 2011). Changes in conduction velocity during fatiguing exercise depend on the degree of fatigue (Rabischong et al, 1995), which closely relates to properties of the individual muscle (Milner-Brown & Miller, 1986).…”

We compared vasti muscle electromyograms for two knee joint angles during fatiguing tetanic contractions. Tetanic contraction of the knee extensors was evoked for 70 s by electrical stimulation of the femoral nerve at knee joint angles of 60° (extended, with 0° indicating full extension) and 110° (flexed) in eight healthy men. Surface electromyography was recorded from the vastus intermedius (VI), vastus lateralis (VL) and vastus medialis (VM) muscles. Knee extension force and M-wave amplitudes and durations were calculated every 7 s, which were normalized by the initial value. Normalized knee extension force was decreased at the flexed knee joint angle compared with that of the extended knee joint angle (P<0·05). Decreased normalized M-wave amplitude and increased normalized M-wave duration of the VI were greater at the flexed knee joint angle than the extended knee joint angle (P<0·05), whereas those for the VL and VM were similar (P>0·05). These results suggest that peripheral fatigue profiles of the VI might be greater at the flexed than the extended knee joint angles, but that of VL and VM might be similar in the tested range of knee joint angles (i.e. 60°-110°) during continuous tetanic contraction induced by electrical stimulation. Therefore, greater reduction of knee extension force at the flexed knee joint angle than the extended knee joint angle may reflect fatigue development of the VI more than other quadriceps femoris components.
