Summary: This study found that MEP significantly increased after anodal transcranial direct current stimulation (a-tDCS), but no significant changes were found in the RPE-clamp or TT tests. This lack of improvement may be attributed to RPE being more controlled by afferent feedback during TT tests than during TTF tests.

Summary: This study investigates the changes in brain network topology during different levels of physical exertion. The results show that high-level force exertions are associated with brain networks characterized by higher clustering coefficients, greater modularity, higher global efficiency, and less distance synchronization.

Summary: This study aimed to examine the interactions between perceived fatigability and performance fatigability in women and men by utilizing the RPE-Clamp model. The findings suggested that the voluntary reductions in torque to maintain RPE and the decreases in neuromuscular efficiency were likely due to group III/IV afferent feedback from peripheral fatigue that resulted in excitation-contraction coupling failure.

Summary: Experiencing mental fatigue before an orienteering race can lead to slower completion time. This study explored the changes in perceived mental fatigue, mood, and other psychological responses during an orienteering competition. The results showed an increase in mental fatigue, fatigue, and physical fatigue after the race, as well as a decrease in motivation, stress, and vigor. It was also found that the recovery from mental fatigue caused by competition was delayed.

Summary: This study aimed to assess the validity of using the Borg CR-10 scale and velocity to predict muscle fatigue assessed by surface electromyography during single joint resistance exercises. The results showed that RPE is useful for assessing fatigue when resistance exercise is performed, but velocity changes may not accurately reflect muscle fatigue.

Summary: RPE is a commonly used method for monitoring and prescribing resistance training during rehabilitation, but it may be affected by neural adaptations induced by rupture and ACL reconstruction, leading to under or overdosing of resistance exercises for patients.

Summary: This study investigated the effects of acute Judo training on performance and perceived fatigue among highly trained collegiate judo athletes. The results showed that neuromuscular fatigue was observed 24 hours after training. Loaded countermovement jump (CMJ) was found to be a better indicator of fatigue compared to unloaded CMJ. Therefore, when arranging high-intensity training, it is important to reduce the training volume appropriately to avoid fatigue accumulation and reduce the risk of sports injuries.

Summary: This study aimed to evaluate the incidence of infusion-related adverse events (IRAE) associated with peripheral administration of 3% sodium chloride. The results showed that the incidence of IRAE was associated with the duration of infusion, and the majority of events were mild with no permanent tissue injury.

Summary: Studies suggest that work rate variations in self-paced endurance exercises directly impact central and peripheral fatigue levels, while central and peripheral fatigue, as well as perceived exertion, play a role in regulating exercise intensity at different stages. Future research should focus on the interactions of fatigue components and their influence on exercise intensity variations throughout the task.

Summary: This study conducted a systematic review and meta-analysis on the diagnostic test accuracy of pedicle screw electrical stimulation. The results showed that lumbar screw stimulation had higher sensitivity and specificity compared to thoracic screws. The study also identified the optimal threshold ranges for lumbar and thoracic stimulation.

Summary: This study examined the role of velocity variability in backstroke performance and found that elite swimmers exhibited higher instability and complexity than good-level swimmers, but there was no difference in intracycle velocity variation. Mean velocity was positively correlated with stability and complexity, and intracycle velocity variation was also related to complexity.

Summary: This study investigated the effects of muscle pain on neuromuscular and neurophysiological responses in the contralateral limb. The results showed that muscle pain can reduce endurance performance time and decrease voluntary force, but had no effect on doublet amplitude and MEP center dot M-max(-1) measures.

Summary: Interoception refers to perceiving and interpreting internal sensations, and the heartbeat tracking task (HTT) is commonly used to assess interoception. However, there is a lack of reliability evidence for this measure, which may threaten interoception assessment. This study found that the HTT showed good relative reliability for interoceptive accuracy and moderate reliability for sensibility and awareness in healthy adults.

Summary: The aim of this study was to evaluate the effects of different visual displays on observers' perception of music performances. The results showed that displays closer to a human form enhanced the perception of expressiveness and music-movement match, while simplified motion displays had the opposite effect. Additionally, performances with projected expressiveness were rated higher than immobile performances. The study highlights the importance of considering the variable display in perceptual studies.

Summary: This study investigated the reliability of pain measures induced by intramuscular injections of hypertonic saline. The results showed good relative reliability for pain intensity and pain quality. However, there was substantial interindividual variability in pain measures. The study concluded that intramuscular injections of hypertonic saline can reliably induce experimental muscle pain.

Summary: This study examined the physiological responses during exercise at FTP and FTP+15W. The results showed that the time to task failure and VO2peak were significantly different between FTP and FTP+15W. Additionally, there was a significant difference in blood lactate levels. Therefore, FTP should not be considered a threshold marker for heavy and severe intensity.

Summary: This review examines the factors that may influence the ergogenic effect of carbohydrate mouth rinse on exercise performance. It finds that carbohydrate mouth rinse enhances endurance exercise performance rather than sprint and strength exercises. The effect is greater in fasting state and factors such as concentration, temperature, and duration of mouth rinse may affect the variability of the effect. Placebo effects also challenge the potential of carbohydrate mouth rinse as an ergogenic aid. Future studies should consider these factors and use proper experimental controls.
