Exercise and mood: A selective review and synthesis of research employing the profile of mood states

Abstract

This paper highlights the use of the Profile of Mood States (POMS) in physical activity research by reviewing and synthesizing literature generated in exercise settings. The results of many studies using the POMS have supported the relationships between exercise and acute mood changes in normal populations and between exercise and chronic mood changes in clinical populations. Based on the multitude of studies utilizing the POMS, Berger and colleagues developed a preliminary taxonomy containing enjoyment, mode, and practice guidelines to help maximize the mood benefits associated with exercise. The POMS also has been employed to identify underlying mechanisms that may promote mood alteration. Unfortunately, there is no conclusive evidence that identifies a single mechanism or group of mechanisms as consistently influencing the exercise-mood relationship. Although knowledge of the relationship between exercise and mood alteration is substantial, much remains to be studied. Promising avenues for future investigation of exercise include mood changes in specific populations, environmental influences on mood alteration, and personal characteristics impacting mood alteration.     

The POMS and sports performance: A review

Abstract

The general purpose of this paper is to critically review the literature on precom-petitive mood states (using the POMS) and sport performance. Specifically, important interpretative, conceptual, and methodological issues are examined to provide direction for future research. A position is taken that the Mental Health Model (iceberg profile) may not be the most suitable framework for understanding how precompetitive mood states are related to sport performance. A promising alternative approach is Hanin's Individual Zone of Optimal Function (IZOF) model.     

Research quality considerations for grounded theory research in sport & exercise psychology

ObjectivesThe aims of this article are: to examine the application of grounded theory in sport and exercise psychology; to locate such applications within broader grounded theory methodological debates and; to support the future use and evolution of the method in the field.MethodsA search of the four sport and exercise psychology journals with the highest impact factors in 2007 (Psychology of Sport and Exercise, Journal of Sport and Exercise Psychology, Journal of Applied Sport Psychology and The Sport Psychologist) using the search term “grounded theory” and the date parameters 2000–2008 was conducted. These articles were discussed in relation to research quality concerns for grounded theory at the micro- and macro-level.ResultsTwelve articles were returned from the search. At the micro-level, eight elements representing collective sufficient conditions for grounded theory were discussed, which only two of the twelve articles returned met. Examples of common mistakes in relation to these elements were provided from the twelve articles. At the macro-level, the ontological and epistemological debates surrounding variants of grounded theory were discussed. Only one of the twelve articles explicitly recognised that there are variants of grounded theory, whilst the potential to generate more generic formal theory, and thus make a wider contribution to bodies of knowledge, was not discussed in any of the articles.ConclusionsThere are research quality concerns regarding the application of grounded theory in sport and exercise psychology at the micro- and macro-level, largely linked to a lack of understanding of the methodology and its implementation. Suggestions to address this for editors, reviewers and authors are offered.     

Magnitude,timing and duration of mood state and cognitive effects of acute moderate exercise in major depressive disorder

BackgroundAcute exercise generally improves mood state and cognitive functioning in healthy adults. However, the impact of acute exercise on primary symptoms in adults with major depressive disorder (MDD) is poorly understood. The present randomized cross-over study evaluated the magnitude, timing, and duration of the psychological effects of 30 min of moderate-intensity cycling exercise compared to quiet rest in 30 adults (21 female) with MDD.MethodsDepressed mood state (Profile of Mood States Short Form-Depression; POMS-D), state anhedonia (anhedonia Visual Analog Scale [VAS], and Dimensional Anhedonia Rating Scale [DARS]), and cognition (inhibition via Stroop and working memory via the 2-back task) were assessed pre, mid, post, 25-, 50- and 75-min after each session.ResultsGeneralized estimating equations demonstrated significant session by time interactions for POMS-D and VAS indicating small-to-large improvements in mood state and anhedonia up to 75 min post-exercise (p < 0.05; Cohen’s d ranges: POMS [-0.69, -0.95]; DARS, [-0.02, 0.16]; VAS [0.33, 0.83]) with greater immediate effects that lessened somewhat across time. For cognition, Stroop reaction time improved during exercise, but was worse at 25- and 50-min post-exercise compared to quiet rest (p < 0.05); no differences were found for 2-back reaction time.LimitationsThe small sample and continued psychological effects at 75 min indicate a potentially longer-lasting response than was measured herein.ConclusionPerforming short bouts of moderate intensity exercise appears to be effective for management of key symptoms (anhedonia, depressed mood state) in adults with MDD. The time immediately post-exercise may be ideal for performing emotionally challenging tasks and/or tasks where a low symptom severity would be helpful (e.g., psychotherapy).     

Assumptions in research in sport and exercise psychology

ObjectivesThe aim of this article is to outline how certain key assumptions affect the quality and interpretation of research in quantitative sport and exercise psychology.MethodsA review of three common assumptions made in the sport and exercise psychology literature was conducted. The review focused on three assumptions relating to research validity and the treatment and interpretation of observations. A central theme to this discussion is the assumption that research observations reflect true effects in a population.ResultsAssumptions often made in sport and exercise psychology research were identified in three key areas: (1) validity, (2) inferences of causality, and (3) effect size and the “practical significance” of research findings. Findings indicated that many studies made assumptions about the validity of the self-report psychological measures adopted and few provided a comprehensive evaluation of the validity of these measures. Researchers adopting correlational designs in sport and exercise psychology often infer causality despite such conclusions being based on theory or speculation rather than empirical evidence. Research reports still do not include effect size statistics as standard and confine the discussion of findings to statistical significance alone rather than commenting on “practical significance”.ConclusionResearch quality can only be evaluated with due consideration of the common assumptions that limits empirical investigation in sport and exercise psychology. We offer some practical advice for researchers, reviewers, and journal editors to minimise the impact of these assumptions and enhance the quality of research findings in sport and exercise psychology.     

The effects of exercise withdrawal on mood and inflammatory cytokine responses in humans

Mechanisms underlying the relationship between exercise and mood are not well understood. This study sought to investigate the role of pro- and anti-inflammatory cytokines and autonomic balance in determining the impact of exercise withdrawal on negative mood. Healthy men and women who regularly exercised (N?=?26, mean age?=?25.5 years, SD?=?4.5 years) were randomised to exercise withdrawal or exercise maintenance for 2 weeks. Protocol adherence was monitored using accelerometers. Inflammatory markers from plasma (interleukin-6, IL-6; tumour necrosis factor-alpha; interleukin-10; and interleukin-1 receptor antagonist), heart-rate variability (HRV) and measures of mood (General Health Questionnaire-28 (GHQ) and the Profile of Mood States (POMS)) were assessed at study entry and at 2-week follow-up. Exercise withdrawal resulted in significant increases in negative mood over time on both the GHQ (p?=?0.028) and the POMS (p?=?0.005). Following the intervention, IL-6 concentration was lower in the exercise withdrawal than exercise maintenance condition (p?=?0.05). No intervention effects were observed for other cytokines or HRV. The mood changes were significantly related to changes in IL-6 concentration (β?=?-?0.50, p?=?0.011), indicating that reduction in IL-6 was related to increased negative mood. Our results are consistent with positive effects of exercise on mental health, but further research on inflammatory pathways is warranted.     

Narrative, identity and mental health: How men with serious mental illness re-story their lives through sport and exercise

ObjectivesIt has been suggested that mental illness threatens identity and sense of self when one's personal story is displaced by dominant illness narratives focussing on deficit and dysfunction. One role of therapy, therefore, is to allow individuals to re-story their life in a more positive way which facilitates the reconstruction of a meaningful identity and sense of self. This research explores the ways in which involvement in sport and exercise may play a part in this process.DesignQualitative analysis of narrative.MethodWe used an interpretive approach which included semi-structured interviews and participant observation with 11 men with serious mental illness to gather stories of participants’ sport and exercise experiences. We conducted an analysis of narrative to explore the more general narrative types which were evident in participants’ accounts.FindingsWe identified three narrative types underlying participants’ talk about sport and exercise: (a) an action narrative about “going places and doing stuff”; (b) an achievement narrative about accomplishment through effort, skill or courage; (c) a relationship narrative of shared experiences to talk about combined with opportunities to talk about those experiences. We note that these narrative types differ significantly from—and may be considered alternatives to—dominant illness narratives.ConclusionThis study provides an alternative perspective on how sport and exercise can help men with serious mental illness by providing the narrative resources which enabled participants to re-story aspects of their lives through creating and sharing personal stories through which they rebuilt or maintained a positive sense of self and identity.     

Peer Leadership in Sport: Relationships among Personal Characteristics,Leader Behaviors,and Team Outcomes

Abstract

The present study comprised two meta-analyses of published studies that used the Profile of Mood States (POMS) to investigate relationships between mood and athletic achievement (n = 13) and between mood and performance outcome (n = 16). Results showed that effect sizes (ESs) for the level of achievement metaanalysis were minimal (Weighted Mean ES = .10, SD = .07), a finding consistent with a previous meta-analysis by Rowley, Landers, Kyllo, and Etnier (1995). Larger effects were found for the performance outcome meta-analysis (Weighted Mean ES = .31, SD = .12). Effects were moderate for vigor, confusion, and depression, small for anger and tension, and very small for fatigue. All effects were in the direction predicted by Morgan's (1985) Mental Health Model. Effects were larger in sports of short duration, in sports involving open skills, and where performance was judged using self-referenced criteria. Findings suggest that the POMS has utility in the prediction of performance outcome but not in the prediction of level of achievement.     

Studying the transgenerational aftereffects of the holocaust in israel

Abstract

A study of 31 patients (20 males and 11 females) at a sports medicine clinic who attributed their injuries to overtraining or overuse was conducted to examine the relationship between causal attribution dimensions and psychological adjustment to sport injury. Participants completed a battery of questionnaires that included the Profile of Mood States (POMS) and an attribution measure in which participants were asked to identify the main cause of their injuries and to rate the perceived cause of injury in terms of internality, stability, and globality dimensions. The attribu-tional dimensions accounted for 55% of the variance (p < .0005) in POMS total mood disturbance (TMD) scores. Internality (ft =– .38, p < .01) and stability (ft = –.58, p < .0005) were inversely related to TMD. These findings were essentially the same when statistically controlling for injury duration, injury severity, and injury status. The findings suggest that attributing overuse injuries to internal and stable factors may have adaptive value.     

A systematic review of religion/spirituality and sport: A psychological perspective

ObjectiveThe study aimed to review the existing literature on religion/spirituality (R/S) in sport from the psychological perspective.DesignA systematic review using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines was employed.MethodThe literature search was completed in December 2018 using five different databases and Google Scholar. The titles and abstracts of the articles were reviewed for the selection process. The selected articles were classified into nine categories: the role of religion/spirituality, consultants, confidence, religious/spiritual faith, flow or being in the zone, identity, anxiety and depression, coping with adversity, and well-being and healing.ResultsA total of 56 studies met the criteria. The selected articles comprised various types of study design that were quantitative, qualitative, mixed-methods, as well as conceptual, review, theoretical, commentary, and perspective articles. The findings show that R/S can play a significant role among athletes in several ways (e.g., coping with uncertainties, building team cohesion, and alleviating anxiety). This study has also uncovered a few issues that should be emphasized for future research such as developing quantitative tools for R/S and sport-performance measurement and designing a religious/spiritual coping strategy that can be used among athletes from various cultures/religions.ConclusionAlthough R/S is often overlooked in sport psychology, the existing literature shows that it can have positive effects on mental health and contribute to achieving better sporting performance.     

The influence of self-reported exercise addiction on acute emotional and physiological responses to brief exercise deprivation

Objectives: To examine the association between self-reported exercise addiction among competitive runners and their emotional and physiological response to a one-day deprivation from scheduled training.Design: A controlled experiment was utilised with random selection to exercise-deprived and control groups to examine the causal link between acute exercise deprivation and the presence and magnitude of withdrawal symptoms.Method: Club-level runners (n=60) who had been training at least five times weekly towards a major regional competition (30 women and 30 men, average age: 24.2 years) volunteered to abstain from a one-day training fixture with less than 24-hours’ notice. All subjects completed the Profile of Mood States (POMS), Running Addiction Scale (RAS) and resting heart rate (RHR) measurements. From this group, 15 men and 15 women were randomly selected to miss the next scheduled training (exercise-deprived group), while the remaining 30 runners continued their training uninterrupted (controls). Both groups repeated POMS and RHR measures within 24 hours after the experiment.Results: The exercise-deprived group reported significant withdrawal-like symptoms of depressed mood, reduced vigour and increased tension, anger, fatigue and confusion (measured by POMS), as well as significantly elevated RHR, within 24 hours after the missed training session. The control group showed no changes in mood or RHR. More importantly, the observed negative mood changes and RHR response in the exercise-deprived group were moderated by self-reported exercise addiction. The sub-median RAS scorers experienced significantly less mood change and RHR shifts than the higher scoring half of the sample. Further, correlations between RAS scores and the magnitude of increases in tension, anger, confusion, depression and RHR ranged from 0.46 to 0.58.Conclusions: Self-reported exercise addiction in habitual exercisers moderates their emotional and physiological responses to a short-term controlled exercise deprivation, indicating that the magnitude of these responses may, in turn, serve as early markers of exercise dependence.     

Evolutionary sport and exercise psychology: Integrating proximate and ultimate explanations

ObjectivesThis review aims to demonstrate the utility of integrating the insights of evolutionary psychology with sport and exercise psychology. Specifically, we offer a primer on evolutionary psychology that we then discuss in the context of several research avenues in sport and exercise. Next, we discuss how evolutionary psychology can inform our understanding of sporting culture.DesignReview paper.MethodsTheory and research are selectively reviewed in efforts to demonstrate the utility and limits of evolutionary psychology as an approach to sport and exercise psychology.Results and conclusionsEvolutionary psychology offers researchers in sport and exercise psychology an improved capacity to produce proximate explanations (i.e., how psychological mechanisms interact with the environment to produce behavior) by generating productive and novel hypotheses from ultimate explanations (i.e., why a psychological mechanism evolved a particular design; Tooby & Cosmides, 1992, 2005). The worth of integrating proximate and ultimate explanations is demonstrated by the ensuing novel insights of popular avenues of sport and exercise psychology including (a) the interrelation between motivation and reasoning and their relative influence on exercise behavior, (b) sex differences in sport participation, (c) performance in sport, and (d) group dynamics in sport. Unlike specific fields of psychology, evolutionary psychology is a metatheoretical approach that can foster mutually productive linkages between currently disparate areas within sport and exercise psychology, and with neighboring disciplines.     

An Exploration of Coaching Research in Journal of Applied Sport Psychology from 1989 to 2017

This article seeks to examine the treatment of coaching research within Journal of Applied Sport Psychology (JASP) and, specifically, to explore whether the Association for Applied Sport Psychology’s mission in recognizing the coach as a performing “other” is being adopted in the field. The study followed a 3-phase design. In Phase 1, an exhaustive search was conducted to identify all coach-related research published in JASP from 1989 to 2017. Phase 2 consisted of accessing the 101 identified articles from a total of 690 articles that had been published in JASP during the review period. In Phase 3, articles were categorized into the multidisciplinary sport and exercise psychology (M-SEP) and contemporary multidisciplinary sport and exercise psychology (C-SEP) periods, and analysis of the articles was completed. Main results indicated that articles that focused on coach perceptions about different topics related primarily to SEP decreased in focus from 40% in the M-SEP period to 23% in the C-SEP period. A prominent focus in both periods was the impact of coaches (often interpersonal behaviors) on their athletes’ performance (M-SEP?=?35%, C-SEP?=?46%). A coach performance focus was coded in only 10% of articles in both periods. Articles decreased in their explicit discussion of how research applied to consulting from 60% to 44% across periods. The findings suggest that currently the literature in JASP does not directly provide SEP professionals with effective knowledge application for working with coaches as a performer within the sport context. This review emphasizes the lack of research positioning of coach as a performing “other” within JASP and may increase awareness of viewing the coach as a performer within the field of applied sport psychology.

Lay Summary: This study was a review of research articles published within the Journal of Applied Sport Psychology (JASP) between 1989 and 2017. Only research with a main focus in coaching was included in the review. A multiple-step process was used to examine the articles and pinpoint the type of research about coaches that was being published in JASP. Results showed a large focus on how coaches contribute to their athletes’ performance, however, a lack of research examining aspects of the coach themselves and how they might enhance their own performance as a coach.     

Developing mixed methods research in sport and exercise psychology: Critical reflections on five points of controversy

ObjectivesTo stimulate debate in sport and exercise psychology about the nature of mixed methods research as currently practiced and how this approach might develop in the future.DesignAn exploration of five points of controversy relating to mixed methods research.MethodA presentation of critical reflections on the following. (1) Mixing methods as a non-debate, (2) Purists, pragmatists and mixing paradigms, (3) Integrating findings and representational forms, (4) Judgment criteria and mixed methods research, and (5) Power, politics and what counts in mixed methods research.ResultsThe examples provided of mixed methods research in action indicate that a number of problematic issues regarding both process and product have been neglected.ConclusionsMixed methods research offers a number of conceptual, practical and pedagogical challenges that need to be addressed if this form of inquiry is to develop its full potential in sport and exercise psychology.     

The Flow-Clutch Scale: Development and preliminary validation in sport and exercise

ObjectivesThe Integrated Model of Flow and Clutch States describes two overlapping psychological states that underlie exceptional performance and rewarding exercise experiences. However, research based on this model is currently hampered because no validated measure has yet been developed. Therefore, the aim of this multi-study paper was to develop and provide preliminary validation of the Flow-Clutch Scale in sport and exercise.DesignUsing two independent adult samples (n = 280; n = 264), three studies were conducted to develop and establish preliminary validity of the Flow-Clutch Scale.MethodIn Study 1, we developed an initial version of the scale and established content validity using an expert panel. In Study 2, we employed exploratory factor analysis to: identify the most appropriate factor structure; examine the scale’s internal consistency; test whether the scale differentiated between individuals who experience flow, clutch, or neither state; and examine relationships with the Flow State Scale-2. In Study 3, we aimed to replicate findings of Study 2 with an independent sample, and employed confirmatory factor analysis to confirm the factor structure, internal consistency, and relationships with the Flow State Scale-2.ResultsThe results provide preliminary validation of the four-factor, 22-item Flow-Clutch Scale.ConclusionsThese studies indicate the Flow-Clutch Scale represents a useful scale for researchers interested in examining flow and/or clutch states in sport and exercise. Recommendations are provided for further research to continue testing, and accumulating evidence for, the validity and reliability of the Flow-Clutch Scale.     

Describing citation structures in sport burnout literature: A citation network analysis

ObjectivesTo evaluate sport burnout research using citation network analysis.DesignA citation network analysis.MethodsWe began by searching the term “sport and burnout” in SportDiscus, Physical Education Index, and PsycINFO. From the returned search, we then selected and analyzed all peer-reviewed English articles that were published before 2012. This allowed us to create a network of inter-citations.ResultsOur search yielded 102 articles, of which there were 11 reviews (11%), 13 qualitative articles (13%), 76 quantitative articles (75%), and two mixed methods (qualitative and quantitative) articles (2%). The 11 most cited articles were published between 1984 and 2006, appearing in 5 journals (7 of them in the same journal). Merely 2 of the most cited articles investigated coach burnout. Top-cited articles typically conducted original research using male and female individual sport athletes and were published by North American authors, with two recent exceptions. The most cited article, and also most influential burnout model, was Smith's (1986) cognitive-affective stress model.ConclusionsThe findings show that following an initial focus on coach burnout, more recent studies examine athletes. In this paper we have identified some strengths amongst the most cited papers, including a wide range of publication dates and a focus on both male and female athletes; however, there were also limitations such as a scarcity of articles investigating team sport athletes.     

Reproducible research in sport and exercise psychology: The role of sample sizes

ObjectivesWe aim to introduce the discussion on the crisis of confidence to sport and exercise psychology. We focus on an important aspect of this debate, the impact of sample sizes, by assessing sample sizes within sport and exercise psychology. Researchers have argued that publications in psychological research contain numerous false-positive findings and inflated effect sizes due to small sample sizes.MethodWe analyse the four leading journals in sport and exercise psychology regarding sample sizes of all quantitative studies published in these journals between 2009 and 2013. Subsequently, we conduct power analyses.ResultsA substantial proportion of published studies does not have sufficient power to detect effect sizes typical for psychological research. Sample sizes and power vary between research designs. Although many correlational studies have adequate sample sizes, experimental studies are often underpowered to detect small-to-medium effects.ConclusionsAs sample sizes are small, research in sport and exercise psychology may suffer from false-positive results and inflated effect sizes, while at the same time failing to detect meaningful small effects. Larger sample sizes are warranted, particularly in experimental studies.
