Brandt, R, Bevilacqua, GG, Coimbra, DR, Pombo, LC, Miarka, B, and Lane, AM. Body weight and mood state modifications in mixed martial arts: An exploratory pilot. J Strength Cond Res 32(9): 2548-2554, 2018-Mixed martial arts (MMA) fighters typically use rapid weight loss (RWL) as a strategy to make competition weight. The aim of the present study was to compare body weight and mood changes in professional male MMA athletes who used strategies to rapidly lose weight (n = 9) and with MMA athletes who did not (n = 3). Body mass and mood states of anger, confusion, depression, fatigue, tension, and vigor and total mood disturbance were assessed (a) 30 days before competition, (b) at the official weigh-in 1 day before competition, (c) 10 minutes before competition, and (d) 10 minutes postcompetition. Results indicated that RWL associated with reporting higher confusion and greater total mood disturbance at each assessment point. Rapid weight loss also associated with high anger at the official weigh-in. However, in performance, RWL did not have deleterious effects on performance. The RWL group also reported greater total mood disturbance at all assessment points with a moderate difference effect size. Research supports the notion that RWL associates with potentially dysfunctional mood states.

Objective: To study sleep parameters and mood profiles of a female explorer traveling solo and unaided to the South Pole during the winter., Methods: During the 44-day expedition, global activity and sleep were assessed using a wrist actigraph (AW) worn on the nondominant wrist. Mood was assessed using an adapted Profile of Mood States questionnaire. Pre- and post expedition physiologic profiles were conducted to assess body composition, strength and power, and aerobic capacity., Results: The AW data revealed decreasing sleep duration throughout the expedition, with an average sleep time of 5 hours (range, 8 hours and 14 minutes to 1 hour and 42 minutes), with sleep times consistently <3 hours during the final third of the expedition. Mood responses indicated a progressive reduction in vigor and increase in fatigue. Sleep time was positively related to vigor and inversely related to depression and fatigue, a finding that is consistent with the notion that positive feelings (high vigor and low fatigue) are linked with sleep., Conclusions: This account provides insight to help understand the limits of human tolerance and may be directly applicable when planning future expeditions of this nature.

The study investigated relationships between game location, performers' experience, and mood states. 31 experienced collegiate soccer players completed the Brunel Mood Scale to assess anger, calmness, confusion, depression, fatigue, happiness, tension, and vigor before eight competitive games (four home and four away). Participants were categorized into Experienced and Less Experienced groups, based on the level of performance at which they played. Repeated-measures multivariate analyses of variance compared mean mood scores across location and experience, and follow-up univariate analyses suggested the increase in mood scores on Tension and decrease in scores on Calmness, Happiness, and Vigor between playing away and at home were significantly greater for Less experienced soccer players than Experienced players. Implications of these findings for the applied practitioner are discussed.

Competition at elite level can require athletes to perform optimally in extreme environmental conditions. This review focuses on mood responses in such conditions and proposes practical guidelines for those working with athletes. Different environments are considered, including altitude and extreme heat and cold. Performing in extreme heat, cold or at altitude can produce a stress response characterized by increased negative mood and relatively poor performance. Positive adaptations to extreme conditions can be accelerated, but the rate of adaptation appears to be highly individualized. Monitoring mood responses to training under normal conditions provides a basis for identifying the psychological effects of extreme conditions. It is suggested that practitioners carefully monitor the interplay between vigour, fatigue and depressed mood. Reductions in vigour and increases in fatigue are normal responses to hard training, but other aspects of mood disturbance, especially symptoms of depressed mood--however small--may be indicative of a maladaptive response, and practitioners should consider intervening when such symptoms first appear.

The purpose of the present study was to investigate the factorial validity of the Brunel Mood Scale, which measures anger, confusion, depression, fatigue, tension, and vigor, for water-skiers. Participants were 345 water-skiers (age range 16 to 39 years, men: n=311, women: n=34) who completed the scale approximately 1 hour before a water-skiing competition. Confirmatory factor analysis indicated support for the validity of the 6-factor model, with a Comparative Fit Index of .90 and Root Mean Squared Error of Approximation of .07. Internal consistency coefficients were above the .70 criterion. It is suggested that the Brunel Mood Scale shows factorial validity for use with water-skiers and that researchers should continue to assess validation of the Brunel Mood Scale with other measures and with specific appropriate samples.

The present study compared the predictive effectiveness of mood states and the Positive and Negative Affect Schedule models of mood. 38 junior high school students completed the Brunel University Mood Scale to assess anger, confusion, depression, fatigue, tension, and vigor and the PANAS 5 min. before a fitness test. Performance was self-referenced by comparing fitness test scores with a previous best score assessed four weeks earlier. Participants who equaled or bettered their previous best score were classified as Successful. Those who did not match their previous score were classified as Unsuccessful. Discriminant function analysis indicated that 31 participants (81.6%) could be correctly classified as Successful or Unsuccessful based on preperformance Brunel Mood scores. Discriminant function coefficients indicated that Confusion, Fatigue, and Vigor contributed significantly to the discrimination. For the Positive and Negative Affect Schedule, discriminant function analysis indicated that 26 participants (68.4%) could be correctly classified as Successful or Unsuccessful, with Negative Affect and Positive Affect contributing significantly to the discrimination. Summarizing negative mood into a single factor may lead to a substantial loss of information. Research on mood and performance relationships should use the mood dimensions assessed in the Brunel University Mood Scale rather than the Positive and Negative Affect Schedule.

This study examined the influence of postcompetition depressed mood on the intensity of other mood dimensions assessed by the Profile of Mood States and relationships between mood and satisfaction with performance. 195 distance runners completed the Brunel Mood Scale which is a 24-item measure assessing anger, confusion, depression, fatigue, tension, and vigor, and a Performance Satisfaction questionnaire immediately after running a 10-mi. race. To examine the proposed moderating effect of depression, participants were separated into a No-depression group of 133 and a Depressed Mood group of 62. Multivariate analysis of variance indicated that the Depressed Mood group reported significantly higher scores on Anger, Contusion, Fatigue, and Tension and lower Vigor scores than the No-depression group t ratios indicated that poorer performance was associated with higher Depression scores. Standard multiple regression to predict Performance Satisfaction scores from postcompetition scores on Anger, Confusion, Fatigue, Tension, and Vigor in the No-depression group indicated that only 1% (Adj. R2=.01, p>.05) of the variance was explained. By contrast, in the Depressed Mood group, the same mood dimensions predicted 27.5% of the variance in Performance Satisfaction scores (Adj. R2=.275, p<.01) with Anger (Beta=.63, p<.001), and Confusion (Beta=.44, p<.05) being significant predictors. Present findings support the notion that depressed mood is related to the intensity of other mood dimensions assessed by the Profile of Mood States and moderates relationships between those scores and performance satisfaction.

26 participants completed a mood measure to assess anger, confusion, depression, fatigue, tension, and vigor immediately before and immediately after two exercise sessions. Analysis showed significant mood enhancement for each exercise session. Follow-up univariate results indicated that Depressed mood scores were reduced significantly and Fatigue scores increased significantly following the first exercise session. Scores after the second exercise session indicated that Depressed mood decreased significantly. There was no interaction. Results lend support for the notion that exercise reduces depressed mood scores. It is suggested that researchers should consider the mechanisms that produce changes in mood following exercise.

Organisations are aware of the need to maintain the mental health of their employees. People's capacity to recognise and manage their moods and emotions is critical to sustainable mental health, performance, and quality of life, while failure to do so can result in underperformance, disengagement, and in some cases, mental illness. Employees of organisations that provide an appropriate strategy and support are likely to experience sustained psychological and mental health benefits. In this paper, we synthesise previous research into a theoretical framework distinguishing mood from emotion via both top-down (cognitive) and bottom-up (biological) factors. We propose a 4R model to help individuals Recognise a mood as distinct from an emotion, or vice-versa, and respond in one of three ways; Restore, Resolve, or Regulate. The model posits mood as an interoceptive signal of internal biological homeostasis, and emotion as a signal of external, often social, events that disrupt homeostasis; mood and emotion serve as internal and external bio-affective feedback loops, respectively. We propose that mood is modified positively by the restoration of homeostasis, whereas emotion is modified positively by behavioural resolution of the emotion-eliciting event. The 4R model is low-cost, preventative, and can be applied peer-to-peer in organisations without expert supervision. [ABSTRACT FROM AUTHOR]

The present study tested and extended Lane and Terry's (2000) conceptual model of mood-performance relationships using a large dataset from an online experiment. Methodological and theoretical advances included testing a more balanced model of pleasant and unpleasant emotions, and evaluating relationships among emotion regulation traits, states and beliefs, psychological skills use, perceptions of performance, mental preparation, and effort exerted during competition. Participants (N = 73,588) completed measures of trait emotion regulation, emotion regulation beliefs, regulation efficacy, use of psychological skills, and rated their anger, anxiety, dejection, excitement, energy, and happiness before completing a competitive concentration task. Post-competition, participants completed measures of effort exerted, beliefs about the quality of mental preparation, and subjective performance. Results showed that dejection associated with worse performance with the no-dejection group performing 3.2% better. Dejection associated with higher anxiety and anger scores and lower energy, excitement, and happiness scores. The proposed moderating effect of dejection was supported for the anxiety-performance relationship but not the anger-performance relationship. In the no-dejection group, participants who reported moderate or high anxiety outperformed those reporting low anxiety by about 1.6%. Overall, results showed partial support for Lane and Terry's model. In terms of extending the model, results showed dejection associated with greater use of suppression, less frequent use of re-appraisal and psychological skills, lower emotion regulation beliefs, and lower emotion regulation efficacy. Further, dejection associated with greater effort during performance, beliefs that pre-competition emotions did not assist goal achievement, and low subjective performance. Future research is required to investigate the role of intense emotions in emotion regulation and performance. [ABSTRACT FROM AUTHOR]

The present study investigated the effects of online self-help interventions on emotions and satisfaction with performance in a sample of runners (N = 147). Participants set themselves a running time goal they wished to achieve, and made goal attempts pre and post-intervention. After the first goal attempt, participants were randomly assigned to 1 of 3 groups: (1) implementation intentions (if-then planning), (2) goal setting, and (3) control group. During both goal attempts, participants reported the intensity of pre-run emotions retrospectively and satisfaction with performance. Results indicated post-intervention emotions were significantly more pleasant and less unpleasant, with more runners reported as performing to expectation. Results also indicated emotion-performance satisfaction relationships strengthened postintervention. Contrary to expectations, implementation intentions did not produce greater benefits when compared to goal-setting intervention and control groups. We suggest that future research should continue to investigate the efficacy of brief online interventions in regulating emotions and performance. [ABSTRACT FROM AUTHOR]

Research into emotion regulation in sport has predominantly focused on intrapersonal regulation of emotion response systems (i.e. subjective experience, cognitions, behaviours or physiological responses). However, researchers in social psychology have suggested that the emotion regulation process is inherently social and interpersonal. This shift represents a significant change in how emotion regulation is conceptualized and, given the intensity of emotions experienced in sport, represents a potentially productive line of enquiry. This review addresses interpersonal emotion regulation in sport, and draws attention to work in social psychology that might inform future sports research. Specifically, the utility of social-functional approaches will be considered. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: Three studies examine the factorial validity, internal consistency, test–retest stability, and criterion validity of the Emotion Regulation Questionnaire (ERQ: ) for use with athletes. Design: Factorial validity, internal consistency, test–retest stability and criterion validity of the ERQ were examined over three stages, using three separate samples. Method: In stage 1 the factorial validity and internal consistency of the ERQ subscales were examined based on responses from 433 sport participants. In stage 2, 176 sport participants completed the ERQ on two occasions separated by an interval of two weeks. In stage 3, the criterion validity of the ERQ was examined. Sport participants (n = 88) completed the ERQ and reported the intensity, frequency and direction of a range of emotions experienced when competing in sport. Results: Confirmatory factor analysis results lend some support to a two-factor model when reappraisal and suppression are allowed to correlate. Alpha coefficients were acceptable. Test–retest stability analyses indicated poor agreement and a greater influence of situational, as opposed to trait factors, in the variance of item scores on the second test administration. In addition, results were partially consistent with findings of : reappraisal scores were associated with pleasant emotions, but suppression scores were not associated with unpleasant emotions. Conclusion: Results provide mixed support for the validity of the ERQ in sport. Because the ERQ is intended to assess stable patterns of emotion regulation, the instability of items is a concern and reasons for this require further investigation. [Copyright &y& Elsevier]

An online survey was used to explore emotion regulation strategies used by runners (N = 506, mean age = 37.69 years, SD = 8.84 years) in the hour prior to training or competition. Content analysis of responses identified 28 categories of emotion regulation strategy, with the most popular being goal setting (23%), distraction (12%), recall of past performance accomplishments (12%), and anticipated pleasant emotions after running (10%). Participants reported greater use of cognitive strategies than behavioural ones, with responses suggesting that emotion regulation and performance management are closely related. Given this cognitive focus, and given the performance aspect inherent to running, it is suggested that individuals' approaches to emotion regulation in sport and exercise contexts differ somewhat from those involved in general daily activities reported in the social psychology literature.

Abstract: Objectives The aim of this study was to investigate relationships between trait emotional intelligence and emotional state changes over the course of an ultra-endurance foot race covering a route of approximately 175 miles (282km) and held in set stages over six days. Design A repeated measures field design that sought to maintain ecological validity was used. Trait emotional intelligence was defined as a relatively stable concept that should predict adaptive emotional states experienced over the duration of the race and therefore associate with pleasant emotions during a 6-stage endurance event. Method Thirty-four runners completed a self-report measure of trait emotional intelligence before the event started. Participants reported emotional states before and after each of the six races. Results Repeated measures ANOVA results showed significant variations in emotions over time and a main effect for trait emotional intelligence. Runners high in self-report trait emotional intelligence also reported higher pleasant and lower unpleasant emotions than runners low in trait emotional intelligence. Conclusions Findings lend support to the notion that trait emotional intelligence associates with adaptive psychological states, suggesting that it may be a key individual difference that explains why some athletes respond to repeated bouts of hard exercise better than others. Future research should test the effectiveness of interventions designed to enhance trait emotional intelligence and examine the attendant impact on emotional responses to intense exercise during multi-stage events.

The present study compared the effects of two different music interventions on changes in emotional states before and during running, and also explored effects of music interventions upon performance outcome. Volunteer participants (n = 65) who regularly listened to music when running registered online to participate in a three-stage study. Participants attempted to attain a personally important running goal to establish baseline performance. Thereafter, participants were randomly assigned to either a self-selected music group or an Audiofuel music group. Audiofuel produce pieces of music designed to assist synchronous running. The self-selected music group followed guidelines for selecting motivating playlists. In both experimental groups, participants used the Brunel Music Rating Inventory-2 (BMRI- 2) to facilitate selection of motivational music. Participants again completed the BMRI-2 post-intervention to assess the motivational qualities of Audiofuel music or the music they selected for use during the study. Results revealed no significant differences between self-selected music and Audiofuel music on all variables analyzed. Participants in both music groups reported increased pleasant emotions and decreased unpleasant emotions following intervention. Significant performance improvements were demonstrated post-intervention with participants reporting a belief that emotional states related to performance. Further analysis indicated that enhanced performance was significantly greater among participants reporting music to be motivational as indicated by high scores on the BMRI-2. Findings suggest that both individual athletes and practitioners should consider using the BMRI-2 when selecting music for running. [ABSTRACT FROM AUTHOR]

This study investigated relationships between self-report measures of emotional intelligence and memories of pre-competitive emotions before optimal and dysfunctional athletic performance. Participant-athletes (n = 284) completed a self-report measure of emotional intelligence and two measures of pre-competitive emotions; a) emotions experienced before an optimal performance, and b) emotions experienced before a dysfunctional performance. Consistent with theoretical predictions, repeated MANOVA results demonstrated pleasant emotions associated with optimal performance and unpleasant emotions associated with dysfunctional performance. Emotional intelligence correlated with pleasant emotions in both performances with individuals reporting low scores on the self-report emotional intelligence scale appearing to experience intense unpleasant emotions before dysfunctional performance. We suggest that future research should investigate relationships between emotional intelligence and emotion-regulation strategies used by athletes. [ABSTRACT FROM AUTHOR]

Relationships between self-report trait emotional intelligence and psychological skills were investigated. Male athletes (54) completed the Emotional Intelligence Scale (EIS; Schutte et al., 1998) and the Test of Performance Strategies (TOPS; Thomas, Murphy, & Hardy, 1999). Canonical correlation results suggested psychological skills used in both competition and in practice relate to perceptions of emotional intelligence (Practice: Canonical R = .69, p < .001; Competition: Canonical R = .67, p < .01). Specifically, self-talk, imagery, and activation in both practice and competition were associated with perceptions of the appraisal of others' emotions and the ability to regulate emotions. The direction of relationships showed that individuals reporting frequent use of psychological skills also reported stronger perceptions of emotional intelligence. Future researchers should seek to establish the direction of relationships by investigating whether increased psychological skills use is associated with enhanced emotional intelligence or vice versa.

Abstract: Our research assessed whether mood and emotion can be measured as distinct constructs. Development and validation of the Emotion and Mood Components of Anxiety Questionnaire (EMCA-Q) is reported. We based the questionnaire on a subjective-contextual model of emotion–mood distinctions, which specifies that differentiation of the emotion of anxiety from an anxious mood should reflect an individual’s awareness of the context in which the respective feeling states occur. In study 1, we describe the development of the 10-item, two factor EMCA-Q. In study 2, we use confirmatory factor analysis to provide support for the factorial validity of the scale. In study 3, we provide preliminary evidence of construct validity by demonstrating that students preparing to submit their thesis reported significantly higher scores of anxious emotion about their thesis than anxious mood. Findings suggested that emotion and mood might be distinguished empirically in line with theoretical predictions when subjective-contextual information used to distinguish between the two states was assessed.
