Spontaneous Behavior

Detrimental mental fatigue effects on exercise performance have been documented in constant workload and time trial exercises, but effects on a maximal incremental test (MIT) remain poorly investigated. Mental fatigue-reduced exercise performance is related to an increased effort sensation, likely due to a reduced prefrontal cortex (PFC) activation and inhibited spontaneous behavior. Interestingly, only a few studies verified if centrally active compounds may mitigate such effects. For example, carbohydrate (CHO) mouth rinse potentiates exercise performance and reduces effort sensation, likely through its effects on PFC activation. However, it is unknown if this centrally mediated effect of CHO mouth rinse may mitigate mental fatigue-reduced exercise performance. After a proof-of-principle study, showing a mental fatigue-reduced MIT performance, we observed that CHO mouth rinse mitigated MIT performance reductions in mentally fatigued cyclists, regardless of PFC alterations. When compared to placebo, mentally fatigued cyclists improved MIT performance by 2.24–2.33% when rinsing their mouth with CHO during MIT. However, PFC and motor cortex activation during MIT in both CHO and placebo mouth rinses were greater than in mental fatigue. Results showed that CHO mouth rinse mitigated the mental fatigue-reduced MIT performance, but challenged the role of CHO mouth rinse on PFC and motor cortex activation.

Objective: The aim of this study was to assess motivation as a factor in mental fatigue using subjective, performance, and physiological measures. Background: Sustained performance on a mentally demanding task can decrease over time. This decrement has two possible causes: a decline in available resources, meaning that performance cannot be sustained, and decrement in motivation, meaning a decline in willingness to sustain performance. However, so far, few experimental paradigms have effectively and continuously manipulated motivation, which is essential to understand its effect on mental fatigue. Method: Twenty participants performed a working memory task with 14 blocks, which alternated between reward and nonreward for 2.5 hr. In the reward blocks, monetary rewards could be gained for good performance. Besides reaction time and accuracy, we used physiological measures (heart rate variability, pupil diameter, eyeblink, eye movements with a video distractor) and subjective measures of fatigue and mental effort. Results: Participants reported becoming fatigued over time and invested more mental effort in the reward blocks. Even though they reported fatigue, their accuracy in the reward blocks remained constant but declined in the nonreward blocks. Furthermore, in the nonreward blocks, participants became more distractable, invested less cognitive effort, blinked more often, and made fewer saccades. These results showed an effect of motivation on mental fatigue. Conclusion: The evidence suggests that motivation is an important factor in explaining the effects of mental fatigue.

Exercise Breaks

Background Breaking up sedentary behavior with standing or walking can decrease discomfort, fatigue, and sleepiness. However, less is known about acceptability and impact of resistance exercise breaks on these outcomes. Therefore, we evaluated the acceptability of resistance exercise breaks and their influence on discomfort, physical and mental fatigue, and sleepiness during occupational sitting. Methods Workers completed two 4-hour conditions in random order: prolonged sitting (SIT) and sitting with hourly resistance exercise breaks (REX). All outcomes were measured at baseline and every hour thereafter with five total breaks. Linear mixed models evaluated overall condition effects and differences at each hour. Cohen’s d estimated magnitudes of effect. Acceptability was assessed via questionnaire after the REX condition and reported as percentages. Findings Fourteen adults (age: 53.4 ± 9.5 years, body mass index [BMI]: 30.9 ± 4.8 kg/m2) were enrolled. Although ratings of discomfort, fatigue, and sleepiness were typically lower during REX as compared with SIT, overall outcomes were not significantly different between conditions ( p > .05). However, a significant reduction in mental fatigue at hour 4 in favor of the REX condition (β = −0.48 log-points, p < .05, d = 0.37) was observed. Program acceptability questions revealed the majority (>50%) of participants reported a “4” or “5” on a 5-point Likert-type scale for all questions, indicating high acceptability for implementation. Conclusions/Application to Practice Resistance exercise breaks had high acceptability and provided preliminary evidence of improving ratings of mental fatigue. More research is needed to better understand the role of resistance training to reduce sedentary behavior.

The Relationship

Background: Pain is a pervasive and disabling barrier for the injured athlete threatening his/her ability to participate in sporting events and professional goals. However, psychological factors in the treatment process of chronic diseases are an important factor in involving the patient in treatment and making treatment decisions. Objectives: This research aimed to investigate the relationship between emotion regulation and pain self-efficacy with psychosocial adjustment in athletes with chronic pain, considering the mediating role of mental fatigue. Methods: The statistical population of this descriptive correlational study was all athletes with chronic pain referred to the Iranian Sports Medicine Federation. Using the convenience sampling method, a total of 200 injured athletes were selected as the sample size. For data collection, Psychosocial Adjustment to Illness Scale (PAIS), Pain Self-Efficacy Questionnaire (PSEQ), Pain Fatigue Scale (PFS), and Cognitive Emotion Regulation Questionnaire (CERQ-short) were used. Descriptive statistics, correlation matrix, and path analysis (structural model) were used to analyze data. Also, SPSS (v21) and AMOS (v23) software were used to analyze the data. Results: According to the results, pain self-efficacy (β = 0.18), adaptive emotion regulation (β = 0.27), and mental fatigue (β = -0.19) had a direct positive and significant impact on psychosocial adjustment. Also, the direct effect of pain self-efficacy (β = -0.19), maladaptive emotion regulation (β = 0.17), and adaptive emotion regulation (β = -0.12) on mental fatigue was significant. In addition, the indirect effect of pain self-efficacy and maladaptive emotions on psychosocial adjustment via mental fatigue was significant. Conclusions: Mental fatigue plays a good mediating role between pain self-efficacy and emotion regulation with psychosocial adjustment of athletes with chronic pain.

Psychosocial risk factors threaten the health of teachers, who are considered to be a group at high risk of suffering burnout syndrome. The objective of this study is to measure the levels of work satisfaction, burnout, engagement, emotional stability, fatigue, and mood of teachers, depending on their workday: intensive or split shift. A nonexperimental, descriptive–comparative research design is proposed for this study. A follow-up questionnaire has been developed to assess a teacher’s levels of physical fatigue, mental fatigue, and mood at the beginning and end of the 9 days of work analyzed. The study sample consisted of 125 teachers (102 women and 23 men) with a mean age of 38.67 years ( SD = 9.51) and 10.02 years of experience in teaching. The results show that the group of teachers working the traditional morning and afternoon shift present greater levels of physical and mental fatigue, worse mood, and less job satisfaction with supervision. However, there were no significant differences in levels of emotional stability, burnout, and engagement between the two groups of teachers. In short, it can be considered that the single morning shift generates higher levels of health among teachers.

Shed Light

Because of the role of mental fatigue in the development of elite soccer players, it has been a topic of interest for researchers in the last decades. First, we aim to shed light on the literature published about mental fatigue in soccer in the last 10 years. Second, based on the results obtained, we propose a new perspective on the role of cognitive effort in soccer. A systematic review (SR) was conducted following the PRISMA guidelines and registered in PROSPERO. A total of 18 articles met the inclusion criteria. The results showed an increase in the publications related to mental fatigue from 2014 onward. They were compared according to focus, sample, instruments and outcomes. Our proposal assumes that physical-physiological, technical-motor and tactical-cognitive demands entail a cognitive load that reduces the performance of players. Studies that prioritise controlling behavioural and physiological responses in cognitive tests are still needed.

AbstractApolipoprotein E ε4 allele (APOE4) has been shown to associate with increased susceptibility to SARS-CoV-2 infection and COVID-19 mortality in some previous genetic studies, but information on the role of APOE4 on the underlying pathology and parallel clinical manifestations is scarce. Here we studied the genetic association between APOE and COVID-19 in Finnish biobank, autopsy and prospective clinical cohort datasets. In line with previous work, our data on 2611 cases showed that APOE4 carriership associates with severe COVID-19 in intensive care patients compared with non-infected population controls after matching for age, sex and cardiovascular disease status. Histopathological examination of brain autopsy material of 21 COVID-19 cases provided evidence that perivascular microhaemorrhages are more prevalent in APOE4 carriers. Finally, our analysis of post-COVID fatigue in a prospective clinical cohort of 156 subjects revealed that APOE4 carriership independently associates with higher mental fatigue compared to non-carriers at six months after initial illness. In conclusion, the present data on Finns suggests that APOE4 is a risk factor for severe COVID-19 and post-COVID mental fatigue and provides the first indication that some of this effect could be mediated via increased cerebrovascular damage. Further studies in larger cohorts and animal models are warranted.
