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 analyzed the effect of postexercise rating times on session rating of perceived exertion (sRPE) in athletes. The results showed that athletes' sRPE can be obtained within a time frame of 5 minutes to 72 hours posttraining, and the effect of rating time seems to be influenced by the training intensity.

Summary: This study investigated the relationship between perceived fatigue, fatiguability, and ratings of perceived exertion (RPE) in individuals with spinal muscular atrophy (SMA). The results showed no significant associations between fatiguability and RPE or physical activity (PA) volume. However, PA was strongly associated with RPE during the 6-minute walk test (6MWT) in SMA individuals who walked fewer than 300 meters. This suggests that RPE cannot be used as a substitute for fatiguability but may be a measure of patient experience during exercise.

Summary: This study retrospectively analyzed 863 exercise test records to evaluate the relationship between ventilatory threshold (VT) and (V)over dotO(2peak), (V)over dotO(2)R, HRR, and RPE. The results showed significant variations in VT at different (V)over dotO(2peak) levels, and the VT%(V)over dotO(2)R followed a U-shaped curve. These findings contribute to the understanding of exercise prescription for individuals with different (V)over dotO(2peak) values.

Summary: This systematic review with meta-analysis investigated the influence of resistance training proximity-to-failure on muscle hypertrophy. The results suggest that resistance training performed to momentary muscular failure is not superior to non-failure resistance training for muscle hypertrophy, and higher velocity loss thresholds do not always elicit greater muscle hypertrophy. There is evidence for a potential non-linear relationship between proximity-to-failure and muscle hypertrophy.

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: The aim of this study was to compare the local and systemic effects of muscle contractions on experimental pain and performance fatigability in people with fibromyalgia and healthy controls. The results showed that individuals with fibromyalgia experienced greater local fatigue but similar systemic fatigue compared to healthy controls, suggesting differences at the muscular level may contribute to changes in performance fatigability in fibromyalgia.

Summary: Exertion can alter running mechanics and increase injury risk. This study found that both forefoot strike (FFS) and increased cadence (CAD) runners exhibited increased load rates with exertion, but the variables affecting the load rates were different for each group. FFS runners had reduced plantarflexion at contact and ankle dorsiflexion excursion, while CAD runners increased vertical stiffness.

Summary: The aim of this study was to analyze the load-velocity and load-power relationships in the free-weight back-squat (BSQ) and hexagonal bar deadlift (HBD) exercises. The results showed that HBD had higher maximum strength, load velocity (30-80% 1RM), and power output (30-90% 1RM) compared to BSQ exercise. There was a strong relationship between load velocity and relative intensity for both exercises. The load that maximized power output was 64.6 +/- 2.9% (BSQ) and 59.6 +/- 1.1% (HBD) 1RM.

Summary: This study evaluated the effects of different exercise intensities on executive functions (EFs), gaze behavior, and pupil diameter. The results showed that psychophysiological measures varied between conditions. Exercise above the lactate threshold (LT) resulted in worse EFs performance compared to rest and exercise below LT. Response time was faster at LT and above LT than at rest, and faster above LT than below LT. Gaze behavior measures indicated that exercise, regardless of intensity, improved the number of fixations with shorter durations. There were no significant differences in average and peak pupil diameter between conditions.

Summary: The aim of this study was to analyze the repeated effect of stroboscopic vision training on perceptual-cognitive skills in soccer players. A total of 28 male soccer players participated in this randomized study with parallel groups. The results showed that both groups exhibited increased multiple object tracking and decision-making skills after the 8-week intervention, with no significant difference between the two groups. However, the stroboscopic vision training group had higher anticipation skill compared to the control group after the intervention. Therefore, repeated stroboscopic vision training could improve anticipation skill in soccer athletes.
