Two new subterranean species of the genus Spelaeogammarus da Silva Brum, 1975 in Serra do Ramalho municipality, Bahia state, and Montes Claros municipality, Minas Gerais state, both in Brazil, are described herein. With these additions, the genus now comprises ten known species. This study includes a comparative table detailing the diagnostic characteristics of all Spelaeogammarus species and an updated genus diagnosis. Additionally, it provides insights into the species’ habitats and the threats they face. Some of the type localities mentioned in this study are not within protected areas, making these species particularly vulnerable to environmental risks. Threats primarily arise from surrounding land use, which can impact the water table and disrupt food resource availability. The discovery of these new troglobitic species underscores the urgent need for their inclusion in future threatened species assessments and highlights the importance of conservation measures to protect both the species and their cave habitats, along with the surrounding landscape. Finally, the discovery of these new species highlights the remarkable diversity of Spelaeogammarus in subterranean environments, emphasizing the need for further research and conservation efforts.

Objective: This study investigated the impact of mental fatigue on the temporal perceptual prediction of action recognition among boxers of different skill levels. Methods: A mixed experimental design of two (groups: Mental Fatigue Expert Group and Mental Fatigue Novice Group) × two (technique types: attack and defense) × three (time shields: −80 ms, −40 ms, and action start) was implemented. Twenty expert and novice boxers participated in this study. Mental fatigue was induced using a 45-min Stroop paradigm, and the effects were assessed using the VAS, Brog-20, BRUMS-F, and BRUMS-V. The experimental procedure for time perception was developed using E-prime 3.0, incorporating 36 videos depicting various attack and defense techniques, and reaction time and accuracy were recorded. Results: (1) A significant main effect on reaction time (RT) was observed (F (1,38) = 5.97, p < 0.05, η² = 0.14) but not on accuracy (ACC), suggesting a pronounced influence of mental fatigue on novice boxers’ temporal perceptual prediction in action recognition; (2) significant main effects of skill types were noted in both RT (F (1,38) = 9.03, p < 0.05, η² = 0.19) and ACC (F (1,38) = 18.496, p < 0.05, η² = 0.327), indicating disparities in the recognition of offensive and defensive skills under mental fatigue; (3) temporal shielding significantly influenced both RT (F (2,76) = 31.42, p < 0.05, η² = 0.45) and ACC (F (2,76) = 125.727, p < 0.05, η² = 0.768), with −80 ms showing a lower RT and ACC compared to −40 ms and action initiation; (4) second-order interaction effects were present in both RT (F (2,76) = 9.85, p < 0.05, η² = 0.21) and ACC (F (2,76) = 8.773, p < 0.05, η² = 0.188), with the RT interaction suggesting a negative impact on perceptual prediction at −80 ms and a faster offensive RT than defensive RT. The ACC interaction indicated that under mental fatigue, −40 ms approached and exceeded −80 ms in both offensive and defensive actions, with higher ACC in offense than defense; and (5) a third-order interaction effect among group, technique type, and time shielding on RT (F (2,76) = 3.92, p < 0.05, η² = 0.09) suggests that mental fatigue more significantly affects novice defensive technique RT than offensive technique. Conclusions: (1) The 45-min Stroop task effectively induced mental fatigue. (2) Mental fatigue negatively impacts both expert and novice boxers, with a more pronounced effect on experts’ defensive skills. (3) The −40 ms time perception is crucial for predicting action recognition as it approaches action initiation. Full article

The psychology of sports officials is often overlooked in psychology research. The present study addressed this disparity by exploring relationships among the mood, stress, and performance of Australian softball umpires. Six male and two female participants aged 25–68 years (M = 48.95 ± 17.39 years) each completed the Brunel Mood Scale before games and provided saliva samples on multiple occasions prior to and after officiating games at two Australian National Softball Championships. Data from 65 games were analysed with performance assessed using Softball Australia’s umpire assessment tool. A significant positive relationship (p < 0.01) was found between tension scores and umpire performance. Using a stepwise regression analysis, tension scores and baseline cortisol level collectively explained 22.6% of the variance in umpire performance scores. These findings suggest that umpires require an optimal level of tension in the period leading up to competition to perform successfully, supporting the relationship between tension and performance first proposed by the inverted-U hypothesis.

The interest in mental health in a sports context has increased in recent years. However, there is no scientifically sound measurement tool for assessing sport-related mental health symptoms in the Finnish language. One of the most frequently used measurement tools for such symptoms in English is the Brunel Mood Scale (BRUMS). The purpose of the present study was to adapt and validate a Finnish version of the BRUMS, referred to as the Finnish Mood Scale (FIMS). The 24-item, 6-factor FIMS was administered to 445 Finnish participants concurrently with Finnish versions of the Depression, Anxiety, and Stress Scale (DASS-21) and the Psychobiosocial States Scale (PBS-S). The sample consisted of 259 females (58.2%), 177 males (39.8%), and 9 who did not disclose their gender (2%), aged 16 to 75 years (M = 35.65, SD = 13.70). Sixty-two participants (13.9%) reported being a competitive athlete, 273 (61.3%) were regular exercisers, and 109 (24.5%) did not exercise regularly. A six-factor modified CFA model indicated an adequate fit to the data (CFI = 0.944, TLI = 0.934, RMSEA = 0.060). Concurrent measures correlated with FIMS in line with theoretical predictions, supporting convergent and divergent validity. Males reported significantly more positive mood scores than females. Physically active participants reported significantly more positive mood scores than inactive individuals, endorsing the mental health benefits of physical exercise. Findings indicate that the FIMS is a suitable measurement tool to screen mood modalities in Finnish populations aged 16 years and older. FIMS may be useful for the early detection of mental ill-health, thus, promoting sustainable mental health. Full article

The balance of mental, physical, and technical aspects is essential in improving ballet performance. Ballet dancers’ emotional and behavioral characteristics vary, even under identical stress conditions. This study aimed to investigate the association between the pain candidate genes 5-HTTLPR and COMT and anxiety in Japanese ballet dancers. Participants were 18 youth elite ballet students with professional aspirations (Y-Elite) and 16 dancers in a professional ballet company (Pro). We administered psychological questionnaires, the State-Trait Anxiety Inventory (STAI) and Brunel Mood Scale (BRUMS), to participants under the following four different stress conditions: standard practice day, cast decision day, rehearsal day, and one week before competition day. In addition, the genotypes of 5-HTTLPR and COMT Val158Met were examined. The distribution of 5-HTTLPR was not different between Y-Elite and Pro dancers, although one of the COMT genotypes was different. Y-Elite dancers had higher trait anxiety scores than Pro dancers for these genotypes before competition (ps < 0.03), although no significant association was observed between both genotypes and scores on the STAI across conditions. Their moods were significantly different through the four conditions (p < 0.004). Pro dancers’ moods were also more stable than those of the Y-Elite dancers in the presence of pain. The results indicate that 5-HTTLPR and COMT play a crucial role in dancers’ anxiety and mood during pain (ps < 0.05). Pro dancers are probably predicted by their lower neuroticism and mood scores and their better adaptation to stress than Y-Elite dancers. The 5-HTTLPR and COMT genes may be influencing the sensitivity to the environment. Youth elite ballet dancers need to understand the relationship between pain and physical activity from an early stage. Full article

This comparative study investigates the effectiveness of two teaching methods, individual verbal encouragement and collective verbal encouragement, in enhancing the technical–tactical skills and mood state of obese students during handball matches. This study employs a randomized controlled design and involves 28 overweight students (50% females), age: 17.4 ± 2.08 years and BMI: 26.8 ± 1.5 for females and 27.3 ± 2.1 for males. Technical–tactical skills are assessed through performance metrics (individual evaluation proposal by Gréhaigne) such as Ball Played (BP), Conquered Ball (CB), Lost Ball (LB), Shoots/Goals, Conservation index, and defensive index, while mood states are evaluated using pre- and post-tests (BRUMS Scale). Results reveal that individual verbal encouragement significantly enhances technical–tactical skills and positively influences the mood state of overweight students compared to collective verbal encouragement. Boys in Session 1 with VEI displayed a significantly higher number of ball plays (mean difference = 0.94 standard deviations, p = 0.004) and conquered balls (mean difference = 0.78 standard deviations, p = 0.006) compared to VEC. They also had a lower number of Lost Balls (mean difference = −0.62 standard deviations, p = 0.018) and a higher shooting efficiency (Shoots/Goals ratio, mean difference = 0.67 standard deviations; p = 0.013). Similar trends were observed in Session 2, with VEI, again, demonstrating advantages. Girls exhibited analogous improvements with VEI in both sessions. Notably, these performance enhancements coincided with positive emotional changes, with VEI leading to a greater decrease in depression and fatigue scores for both boys and girls. The study highlights the importance of tailoring teaching methods to the specific needs of overweight students in the context of handball, emphasizing the effectiveness of individualized verbal encouragement for skill development and emotional well-being. These findings offer practical implications for educators and coaches involved in physical education, advocating for personalized approaches to optimize learning experiences for overweight students in sports settings.

Mood profile clusters have previously been identified in several cultural contexts. In the present study, six mood profile clusters referred to as the iceberg, inverse Everest, inverse iceberg, shark fin, submerged, and surface profiles, were investigated in a Greek population. The names of the mood profiles reflect how they appear after raw scores for Tension, Depression, Anger, Vigor, Fatigue, and Confusion (in that order), are converted to T-scores and depicted graphically. A Greek translation of the Brunel Mood Scale (BRUMS-Greek) was completed by 1786 adults, comprising 1417 exercise participants and 369 physically inactive adults (male = 578, female = 1208) aged 18–64 years (M = 34.73 ± 11.81 years). Although the male–female ratio emphasized females, sample sizes of over 500 suggest some degree of representativeness. Seeded k-means cluster analysis clearly identified the six hypothesized mood profiles. Men were over-represented for the iceberg profile. For age, the 18–25 years group were under-represented for the iceberg profile, whereas the 46–55 and 56+ years groups were over-represented. The 56+ years group were under-represented for the inverse Everest, and the 18–25 years group were over-represented for the shark fin profile. For body mass index (BMI), participants in the obese weight category were over-represented for the inverse iceberg and shark fin profiles and under-represented for the submerged profile. Active participants were over-represented for the iceberg and submerged profiles, and under-represented for the inverse Everest, inverse iceberg, and surface profiles. Findings supported the cross-cultural equivalence of the mood profile clusters and confirmed the link between physical inactivity, obesity, and negative mood profiles. Full article

COVID-19 affected health and wellbeing globally. Graduating nursing students face a variety of stressors, and entering the nursing profession during the pandemic adds additional stress. Using a quantitative cross-sectional design, mood, perceived stress, resilience, and coping were assessed in an Australian sample of 112 graduating nursing students, who completed the Brunel Mood Scale (BRUMS), Perceived Stress Scale (PSS-4), and Brief Resilient Coping Scale (BRCS). Mean BRUMS scores for tension, fatigue, and confusion were significantly above population norms and vigour scores were significantly below. Mean PSS-4 scores were reflective of population norms but showed higher levels of stress among younger and on-campus students compared to those who were older or studied externally. BRCS data showed that 82.1% of graduating nursing students were medium- or high-resilient copers. Mood profiles suggested that 19.6% of participants reported moods associated with mental health issues, 23.2% reported moods associated with risk of burnout, and only 17.9% reported mood profiles associated with positive mental health. High mean tension scores reported by graduating nursing students indicated apprehension about joining the profession, although stress, resilience, and coping scores suggested they were adequately managing the additional stressors generated by the global pandemic.

Lean bodybuilder athletes may encounter challenges in adapting their eating habits during ad libitum refeed, either intuitively or consciously. Aims: This paper investigates whether there is a relationship between adaptive eating and energy intake coping strategies in a refeed model for bodybuilders. Methods: Fourteen male bodybuilders (29.6 ± 3.1 years; 85.6 ± 6.8 kg, ≥6 competitions) completed a 4-week regimen consisting of 5 days of energy restriction followed by 2 days of refeed. Dietary assessment, body composition (ultrasound), recovery stress questionnaire (REST-Q) and Brunel mood scale (BRUMS) were utilized pre- and post-regimen. Coping function questionnaire (CFQ), mindful eating scale version 2 (MES 2) and the intuitive eating scale-2 (IES-2) were evaluated at the 4th week. Results: Compared to the initial values, the refeed day resulted in a daily caloric increase of 44% compared to the average energy intake on the energy restriction days, culminating in a weekly calorie deficit of 27% and a drop in body mass of 3.1 ± 1.4%. Most participants showed reduced body fat and preserved or gained lean mass. The energy consumption during the refeed maintained an inverse relationship with the perception of satiety (r = −0.9; p < 0.01), the IES 2 total scores (r = −0.82; p < 0.01), as well as the confidence in hunger and satiety cues (r = −0.62; p = 0.02) and congruence in food–body choice dimensions (r = −0.56; p = 0.04). Emotional coping maintained an inverse relationship with the IES 2 total scores (r = 0.54; p < 0.05) and an inverse relationship with energy intake during refeed (r = −0.42; p < 0.05). Conclusion: The results suggest that a heightened perception of internal hunger and satiety signals and higher scores in intuitive eating may contribute to adequate energy intake, even when high scores of emotional coping are present.

The aim of the present study was to provide initial validity evidence of a Greek translation of the 24-item Brunel Mood Scale, referred to as the BRUMS-Greek, a measure of anger, confusion, depression, fatigue, tension, and vigour. Data were collected from 1417 Greek adult exercise participants and 369 physically inactive adults, totaling 1786 adults (male = 578, female = 1208) aged 18–64 years (M = 34.73 ± 11.81 years). Given the large univariate and multivariate non-normality, a confirmatory factor analyses treating responses as ordered categorical variables was conducted which supported the hypothesised six-correlated factor measurement model. The internal consistency reliability of the BRUMS-Greek subscales was supported via Cronbach alpha coefficients. The construct validity of the scales was supported (a) via correlations in the hypothesised direction with trait positive and negative affect, (b) with more positive and less negative moods reported immediately after participation in a single exercise class compared to pre-exercise mood, and (c) with exercise participants reporting more positive and less negative mood states compared to physically inactive adults. Women reported higher tension and lower vigour scores than men. Tension scores were higher and confusion scores lower among younger participants (≤35 years) than older participants (≥36 years). Participants with obesity reported higher negative mood scores than those who were underweight or normal weight. In sum, the BRUMS-Greek demonstrated acceptable psychometric characteristics, and is proposed to be a suitable measure for use with exercise participants, physically inactive adults, and other Greek populations to explore research questions related to mood.

The aim of this study was to assess the effect of acute short- versus long-interval high-intensity interval training (HIIT) on cognitive performance and psychological states in secondary school students. Fifteen secondary school students (nine males and six females: mean age = 16.2 ± 0.4 years, mean Body Mass Index = 21.2 ± 1.5 kg/m², and maximum oxygen uptake = 42.2 ± 5.9 mL/kg/min) participated in the current study. They performed one of the following three sessions in a randomized order: (i) a long-interval HIIT (LIHIIT), (ii) a short-interval HIIT (SIHIIT), and (iii) a control condition (CC). Cognitive performance and perceived exertion were assessed pre and immediately post each condition using the d2 test and the Rating of Perceived Exertion (RPE) tool, respectively. Mood state was quantified using the Brunel Mood Scale (BRUMS) questionnaire immediately post each condition. The findings reported higher concentration performance in the SIHIIT compared to the LIHIIT condition (p = 0.043) and the CC (p < 0.001) and in the LIHIIT compared to the CC (p = 0.023). Moreover, the total count of errors was higher in the CC than in the LIHIIT (p = 0.01) and in the SIHIIT conditions (p < 0.001) and in the LIHIIT than in the SIHIIT condition (p = 0.03). RPE value was higher in the LIHIIT and SIHIIT conditions than in the CC (both p < 0.001), whereas no statistically significant difference between LIHIIT and SIHIIT conditions (p = 0.24) was found. Regarding the BRUMS, a significant difference between conditions in the fatigue subscale was found, being higher in LIHIIT with respect to SIHIIT (p = 0.03) and CC (p < 0.05). Vigor differed between conditions, with a higher value than in the LIHIIT (p = 0.04) and CC (p < 0.001). All the remaining subscales did not significantly differ between conditions (p > 0.05). Practitioners may implement short-interval HIIT prior to any tasks that require high levels of visual attention. Full article

In our study, we translated and tested the psychometric properties of an Arabic version of the Brunel Mood Scale (BRUMS), referred to as the Arabic Mood Scale (ARAMS), among physical education university students. A total of 681 participants completed the ARAMS in exploratory and confirmatory phases. Exploratory analyses were conducted on data from 253 students between the ages of 19 and 25 years (M = 21.14 ± 1.65 years) of whom 132 were women (52.2%) and 121 were men (47.8%). Confirmatory analyses were conducted on data from 428 students between the ages of 19 and 25 years (M = 20.93 ± 1.55 years) of whom 203 were women (52.6%) and 225 were men (47.4%). The measurement model of the ARAMS was initially evaluated using exploratory factor analysis (EFA) and was subsequently tested via confirmatory factor analysis (CFA). EFA identified a 24-item, 6-factor structure that aligned with the original BRUMS measurement model, and CFA demonstrated congruence between the two models. Internal consistency of the six subscales exceeded adequacy levels with good Cronbach’s alpha and McDonald’s Omega values respectively for anger (0.811; 0.812), confusion (0.830; 0.830), depression (0.858; 0.859), fatigue (0.823; 0.825), and tension (0.824; 0.825), and an acceptable value for vigor (0.749; 0.748). Findings support the factorial validity and internal consistency of the ARAMS, which appears to be a suitable measure for use in Arabic physical education contexts. Further validation studies are required before the ARAMS is used in other Arabic-language contexts. Full article

Mood measures have been shown to have utility for monitoring risks to mental health and to predict performance among athletes. To facilitate use in a Malaysian context, we tested a Malay-language version of the 24-item Brunel Mood Scale (BRUMS), referred to as the Malaysian Mood Scale (MASMS). Following a thorough translation–back-translation process, the 24-item MASMS was administered to 4923 Malay-speaking respondents (2706 males, 2217 females; 2559 athletes, 2364 non-athletes), ranging in age from 17 to 75 years (M = 28.2 years, SD = 9.4 years). Confirmatory factor analysis supported the six-factor MASMS measurement model (CFI = 0.950, TLI = 0.940, RMSEA = 0.056 [CI 0.055, 0.058]). Convergent and divergent validity of the MASMS were supported via relationships with depression, anxiety, and stress measures. Significant differences in mood scores were found between athletes and non-athletes, males and females, and younger and older participants. Tables of normative data and profile sheets for specific groups were generated. We propose that the MASMS is a valid measure that can be used to monitor mental health status among athletes and non-athletes and that facilitates future mood-related research in Malaysia.

The purpose of this study was to evaluate the effects of a progressive muscle relaxation program on psychological (stress levels, anxiety, and mood states) and physiological (blood pressure and heart rate) variables in basketball athletes. Fifty-nine basketball players, aged 14 to 19 years, and members of Bauru Basket team, were recruited for this study and grouped into control group (CG, n = 30) and intervention group (IG, n = 29). The participants were evaluated, before and after the intervention, by the following means: Competitive State Anxiety Inventory-2 (CSAI-2), to measure the pre-competitive anxiety state, i.e., how anxious each athlete felt just before the competition; Brunel Mood Scale (BRUMS), an instrument for early detection of overtraining syndrome; Recovery-Stress Questionnaire for Athletes (RESTQ-Sport), to identify the extent to which each athlete was physically or mentally stressed and the athlete’s current capability for recovery; Athlete Burnout Questionnaire (ABQ), specifically developed for athletes. The IG athletes participated in 12 progressive muscle relaxation sessions, a practice for tensing or tightening a specific muscle until an ideal state of relaxation is reached. Each participant had blood pressure and heart rate measured before and after every session. The CG athletes were evaluated similarly to those in the IG but without relaxation. The results showed statistically significant differences in cognitive anxiety (p = 0.039) and specific stress (p = 0.016) between CG and IG before the intervention; in addition, a significant heart rate decrease (p < 0.01) between IG and CG was noted.

The objective of this investigation was to explore in a sample of female students the effects of several acute plyometric training intensities (low, moderate, and high—55–65%, 70–80%, and 90–100% of maximal vertical jump performance, respectively) on cognition (attention) and psychological states (mood). Thirty-seven female students (mean age = 19.72 ± 0.73 years, mean body mass index = 19.51) participated in the current study. They were randomly allocated to one of three conditions: a high-intensity plyometric exercise (HIPE), a moderate-intensity plyometric exercise (MIPE), and a low-intensity plyometric exercise (LIPE). Before and immediately after each session for the three conditions, all participants underwent a cognitive performance test (d2 test) and filled in a battery of psychological questionnaires (the Rating of Perceived Exertion (RPE), and the Brunel Mood Scale (BRUMS)). The data reported higher concentration performance and a lower number of errors in the MIPE when compared with HIPE (all, p-value < 0.05) groups, whereas no significant difference was found between other conditions (p-value > 0.05). The RPE value was higher in the HIPE (p-value < 0.001) and MIPE (p = 0.01) than in the LIPE, and in the HIPE than in the MIPE (p = 0.001) conditions. Concerning the BRUMS scale, fatigue (p = 0.005) was significantly different among the various conditions, being higher in HIPE with respect to MIPE and LIPE (all, p-value < 0.05) conditions. In conclusion, moderate-intensity plyometric exercise can be considered the best activity to improve visual attention. Practitioners may practice moderate-intensity plyometric exercises to improve concentration performance. However, due to the limitations of the present study (lack of a control group and between-subjects study design), further research in the field is warranted. Full article
