“…All measurements were performed on the participants' right leg. Fatigue task-induced changes in MVC torque were considered the index of both peripheral and central fatigue [19]. Potentiated triplet torque was considered to reflect peripheral fatigue [20].…”

This study investigated the effect of 1-week oral administration of propolis on muscle fatigue and recovery after performing a fatigue task (total 100 maximal voluntary concentric knee extension repetitions). In this placebo-controlled, double-blind study, 18 young men consumed a formulation with high Brazilian green propolis dose (H-BGP), a formulation with low Brazilian green propolis dose, or a placebo, for 1 week before performing the fatigue task (an interval between each intervention: 1–2 weeks). Maximal voluntary contraction torque, central fatigue (voluntary activation and root mean square values of the surface electromyography amplitude), and peripheral fatigue (potentiated triplet torque) were assessed before, immediately after, and 2 minutes after the fatigue task. Maximal voluntary contraction torque decreased immediately after the fatigue task in all conditions (P<0.001); however, it recovered from immediately after to 2 minutes after the fatigue task only in the H-BGP condition (P<0.001). Furthermore, there was a significant decrease in voluntary activation (P<0.001) and root mean square values of the surface electromyography amplitude (P≤0.035) only in the placebo condition. No significant difference was observed in the time-course change in potentiated triplet torque between the conditions. These results suggest that oral administration of propolis promotes muscle fatigue recovery by reducing central fatigue.

“…Approximately 15-20 s after the end of the fatiguing task, once the TQTRI was obtained and rest was confirmed, the participants performed a single knee extension MVC for 4 s to assess TQMVC and VA% after ensuring that they were at rest. Fatiguing task-induced changes in TQMVC and VA% reflected both peripheral and central fatigue and central fatigue, respectively 10,11) .…”

Identifying the factors that contribute to individual differences in mid-level intensity neuromuscular fatigue is essential to improve performance and effective exercise in training and rehabilitation. This study investigated factors affecting individual differences in knee extensor fatigue induced by sustained isometric mid-level contractions. Twenty-six healthy young men performed a sustained fatiguing contraction to task failure at 40% maximal voluntary contraction (MVC) torque of the knee extensors. The MVC torque (TQ MVC), evoked triplet torque (TQTRI), and voluntary activation (VA%) of the knee extensors were determined before and after the fatiguing task. Differences in TQMVC, TQTRI, and VA% before and after the fatiguing task were examined, and the relationship between TQMVC and TQTRI or VA% after the fatiguing task normalized to baseline was examined using Pearson product-moment correlation analysis. TQMVC and TQTRI decreased significantly after the fatiguing task (31.1% decrease for TQMVC, 38.8% decrease for TQTRI, p < 0.001), whereas VA% did not change significantly (4.2% increase for VA%, p = 0.057). After the fatiguing task, the normalized TQMVC was significantly correlated with the normalized TQTRI (r = 0.617, p < 0.001), but not with the normalized VA% (r = 0.348, p = 0.082). Individual differences in knee extensor fatigue induced by sustained mid-level contraction were more affected by peripheral fatigue than by central fatigue. Therefore, focusing on fatigue resistance in peripheral areas is important to improve endurance in moderate-intensity exercises.
