Exercise dependence and the drive for muscularity in male bodybuilders,power lifters,and fitness lifters

Researchers have hypothesized differences in exercise dependence and drive for muscularity between bodybuilders and power lifters, while others have not found the predicted differences. This study assessed 146 weight lifters (bodybuilders, n = 59; power lifters, n = 47; fitness lifters, n = 40) on the Exercise Dependence Scale, Bodybuilding Dependence Scale, and the Drive for Muscularity Scale. Results showed that bodybuilders and power lifters were significantly higher than fitness lifters on EDS Total, 7 EDS scales, and the 3 BDS scales. In contrast, power lifters were found to be significantly higher on DMS Total and DMS Behavior scales than bodybuilders. The regression results suggest that exercise dependence may be directly related to the drive for muscularity.     

Genetic associations with personality and mental toughness profiles of English academy football players: An exploratory study

Psychological characteristics influence the performance of youth football players and are significant predictors of development and success at adulthood. Although genetic factors may explain a considerable portion of inter-individual differences in psychological traits, psychogenetic research in football is scarce. As such, the purpose of this study was to examine the association of ten single nucleotide polymorphisms (SNPs) with personality and mental toughness profiles of academy football players. Seventy-three male under-12 to under-18 football players from a Category 3 English academy were genotyped for ten SNPs. Personality and mental toughness were assessed using a 50-item IPIP Big Five personality traits questionnaire and the Mental Toughness Index, respectively. Simple linear regression was used to analyse individual SNP associations with personality dimensions and mental toughness, whereas both unweighted and weighted total genotype scores (TGSs; TWGSs) were computed to measure the combined influence of all SNPs. There was a significant association between DRD3 (rs167771) and agreeableness (p = .043), where A/A homozygotes scored higher than G allele carriers. TGSs and/or TWGSs were significantly correlated with mental toughness and each personality dimension except openness, explaining between 3 and 17% of the variance. The results of this study suggest psychological characteristics of youth football players are partly determined by genetic factors.     

Perspectives on the home advantage: A comparison of football players, fans and referees

Objectives

The study aimed to address the paucity of research pertaining to perceptions of causes of the home advantage. The views of three key personnel groups in football (soccer) were examined with regard to their perspectives.

Design and procedure

Players (n = 94), fans (n = 116) and referees (n = 163) completed a ten-item questionnaire on which they rated the contribution of the most prominent factors known to influence the home advantage.

Results

Factor analysis revealed three subscales (officials, player state and home environment) relating to explanations for the home advantage. A MANOVA examining the groups’ ratings for these three subscales found that the fans and player gave higher ratings for the contribution of officials and player state than did referees, while the fans gave higher ratings for the home environment.

Conclusion

The present study provides an insight into conceptualisations of the home advantage from the perspectives of different football groups. The relevance of self-enhancement, emanating from motivational and information processing mechanisms, is considered.     

Psychopathic Traits of Dutch Adolescents in Residential Care: Identifying Subgroups

The present study examined whether a sample of 214 (52.8% male, M age = 15.76, SD = 1.29) institutionalized adolescents could be classified into subgroups based on psychopathic traits. Confirmatory Factor Analyses revealed a relationship between the subscales of the Youth Psychopathic traits Inventory (YPI) and the three latent constructs of the original model on which it is based. Latent Class Analyses showed that adolescents showing psychopathic traits could be classified into three subgroups. The first group showed low scores on the grandiose/manipulative dimension, the callous/unemotional dimension, and the impulsive/irresponsible dimension (normal group). The second group scored moderate on the grandiose/manipulative dimension and the callous/unemotional dimension and high on the impulsive/irresponsible dimension (impulsive, non-psychopathic-like group). The third group scored high on all three dimensions (psychopathy-like group). The findings revealed that the impulsive, non-psychopathic like group scored significantly higher on internalizing problem behavior compared to the normal group, while the psychopathy-like and the impulsive, non-psychopathic-like group both scored higher on externalizing problem behavior compared to the normal group. Based on a self-report delinquency measure, it appeared that the psychopathy-like group had the highest delinquency rates, except for vandalism. Both the impulsive and psychopathy-like group had the highest scores on the use of soft drugs.     

Implementation of a mindfulness-based stress reduction (MBSR) program to reduce stress,anxiety, and depression and to improve psychological well-being among retired Iranian football players

ObjectivesTo test whether a mindfulness-based stress reduction (MBSR) program could reduce symptoms of anxiety, stress, and depression, and increase psychological well-being among retired Iranian football players compared to an active control group.DesignRandomized controlled trial, with an 8-week MBSR intervention (16 group sessions, 90 min each) and an active control group. Three data assessments were performed at baseline, eight weeks later after completion of the intervention, and again twelve weeks later at follow-up.MethodsForty male retired football players (M_age = 34.05, SD = 1.72) were randomly assigned either to the MBSR intervention or the active control condition. All participants completed questionnaires on perceived stress, anxiety, depression, and psychological well-being. Repeated measures analyses of variance were used to assess time by group interactions.ResultsSignificant time by group interaction effects were found for all outcomes. In the MBSR group, psychological well-being improved and symptoms of stress, anxiety, and depression decreased over time from baseline to intervention completion and to follow-up. In the active control group, the outcomes remained relatively stable across time.ConclusionsThe present findings suggest that among male retired Iranian football players, a MBSR intervention has the potential to reduce symptoms of stress, anxiety, and depression, and to increase their psychological well-being. Potential (underlying) mechanisms were not assessed in the present study. In future investigations, researchers should try to gain a deeper understanding of the mechanisms which may explain the observed effects.     

Do developmental differences in mental toughness exist between specialized and invested Australian footballers?

Using a cross-sectional design, the primary purpose of the present study was to examine developmental differences in mental toughness between specialized and invested Australian footballers. A secondary purpose was to examine the psychometric properties of the Australian football Mental Toughness Inventory (AfMTI; Gucciardi, Gordon, & Dimmock, 2009a) with a sample of youth footballers. Participants were 350 footballers aged between 13 and 18 (M = 15.88; SD = 1.71); 144 (M_age = 14.06; SD = .89) and 206 (M_age = 17.02; SD = 1.06) footballers from the specialized and investment developmental stages, respectively. A confirmatory factor analysis of the AfMTI using AMOS did not reveal support for its psychometric structure; however, a revised version received support. A MANOVA revealed the presence of a significant difference between the two developmental groups, and follow-up ANOVA’s indicated that the desire success and sport awareness subscales contributed to multivariate effect. It appears that developmental differences should be considered in future theorizing on the development of mental toughness.     

Joint attention in term and preterm infants at 12 months corrected age: the significance of gender and intervention based on a randomized controlled trial

This study tested the effects of optimized neonatal mother–infant transactions on joint attention performance at 12 months. Surviving infants <2000 g from a geographically defined area were randomly assigned to a preterm intervention (n = 71) or preterm control group (n = 69). Comparisons were made between preterm groups, secondary with a term group (n = 75). Joint attention was measured using the Early Social Communication Scales. Preterm intervention infants scored significantly higher than preterm control infants on elements Initiating Joint Attention (p < 0.05), Initiating Object Requests (p < 0.05), and Responding to Social Interaction (p < 0.0005). Intervention was not associated with performance on elements Responding to Joint Attention, or on Responding to Requests. ELBW infants scored significantly lower than VLBW and LBW infants on imperative functions. Girls outperformed boys on all communication elements. An intervention implemented during the neonatal period can be of advantage for certain aspects of joint attention performance in preterm infants.     

Overcoming Negative Aspects of Perfectionism through Group Treatment

The tendency to hold and pursue excessively high standards for oneself and for others can interfere with academic achievement. Counsellors who work in university settings are often presented with students whose capabilities do not reflect their levels of achievement. This study reports on the evaluation of an eight-week group intervention designed to help university students shift from negative and often debilitating perfectionism to positive and enhancing perfectionism. The group treatment focused on changing attitudes, beliefs, feelings, and interpersonal interactions affected by perfectionism using combined cognitive-behavioral and interpersonal approaches. Standardized measures, including the Beck Depression Inventory (Beck et al., BDI-II manual. San Antonio: The Psychological Corporation, 1996), the Beck Anxiety Inventory (Beck and Steer, Beck Anxiety Inventory: Manual. San Antonio: The Psychological Corporation, 1993), and the Multidimensional Perfectionism Scale (Hewitt and Flett, Journal of Personality & Social Psychology, 60, 456–470, 1991a), provided data for pre- and post analysis of a treatment group (n = 30), and comparison groups of students attending group programs on career planning (n = 30) and attending psychology classes (n = 30). Results show that students participating in the treatment group significantly reduced their levels of depression, anxiety, and perfectionism in comparison to students who did not attend the treatment program. Implications of the findings suggest the importance of considering perfectionism on a continuum of negative and positive influences while helping students to address the intrapersonal and interpersonal dimensions of perfectionism.     

Emotional Intelligence in Social Phobia and Other Anxiety Disorders

This study examined the associations between clinical anxiety, domains of emotional intelligence (EI), and three clinician-rated indices of maladjustment. Of key interest was whether social phobia (SP) is unique among anxiety disorders in being characterized by lower levels of Interpersonal and, particularly, Intrapersonal EI, and whether these differentially predict maladjustment. Individuals with SP (n = 169) obsessive-compulsive disorder (n = 65) and panic disorder (n = 64), and nonclinical controls (n = 169) completed the short form self-report Emotional Quotient Inventory (EQ-i: S). All anxiety disorder groups showed lower total EI than controls, and differed among themselves with the SP group displaying the lowest levels of total EI and lower scores on two EQ-i:S subscales (Interpersonal and, more robustly, Intrapersonal). The Intrapersonal dimension alone predicted all indices of greater maladjustment in the SP group. These findings indicate a negative relationship between anxiety disorders and EI, and reaffirm the foremost link between Intrapersonal EI and SP and its functional outcomes.     

Modulation of brain oscillations during fundamental visuo-spatial processing: A comparison between female collegiate badminton players and sedentary controls

ObjectivesThe present study aimed to investigate the difference in fundamental cognitive processing and neural oscillations between badminton players and sedentary controls.DesignA cross-sectional design was adopted to address this issue.MethodsWe compared time-frequency electroencephalographic (EEG) activity from collegiate female badminton players (n = 12, aged 20.58 ± 2.75 years) and age-and gender-matched sedentary non-athletic controls (n = 13, aged 19.08 ± 2.10 years) when they performed a task that involves visuo-spatial attention and working memory.ResultsWe observed that players responded faster than controls on the task without suffering any increase in error responses. Correspondingly, the players, relative to controls, exhibited higher task-related modulations in beta power in the attention condition as well as in theta and beta power in the working memory condition. Notably, the behavior-EEG correlations revealed that better attention performance is associated with lower beta power, while greater working memory is related to higher theta power.ConclusionsOur results shed light on the mechanisms of athletic superiority in fundamental cognitive functioning: the higher theta synchronization points to a greater engagement of attention, whereas the higher beta desynchronization supports the contribution of processing speed (or motor-related processing) to better performance in athletes. This study extends current understanding by suggesting that enhanced neurocognitive function seen in athletes may transfer to fundamental tasks, giving insight into the generalizability of sport experience to neurocognitive functioning.     

Big men feeling small: Childhood bullying experience, muscle dysmorphia and other mental health problems in bodybuilders

ObjectivesMuscle dysmorphia (MD) is a preoccupation with the idea that one's body is insufficiently lean and muscular and considered as a body image disorder in men. This study aimed to investigate the relationship of MD with childhood bullying victimization experiences and mental health problems in a nonclinical sample of male bodybuilders.DesignA cross-sectional study was conducted with a sample of 100 male bodybuilders.MethodsParticipants completed a questionnaire battery consisting of the muscle dysmorphic inventory (MDI), and scales on childhood bullying victimization, self-esteem, and psychological problems including depression, anxiety and obsessive-compulsive (OC) symptoms.ResultsHigh scores on the MDI and bullying victimization in childhood predicted global psychopathology and low self-esteem. Psychological functioning and self-esteem were most strongly adversely affected if the men were victims of bullying and scored high on the MDI (significant moderation effect). Structural equation modeling (SEM) analyses furthermore found an indirect linkage of victimization with global psychopathology and self-esteem via MDI (mediation effect).ConclusionsChildhood bullying victimization and MD are strongly associated with concurrent anxiety, depressive and obsessive-compulsive symptoms and low self-esteem.     

Initial Validation of the Children’s Worry Management Scale

We investigated the psychometric properties of a new instrument, the Children’s Worry Management Scale (CWMS). The CWMS has three subscales that specify methods of regulating worry: inhibition (the suppression of worry), dysregulation (exaggerated displays of worry), and coping (constructive ways of managing worry). Using a Caucasian, middle-class sample of 214 children (M = 9 years, 1 month), Study 1 provides reliability and validity data through patterns of correlations to parent- and child-completed measures of emotion management and behavioral problems. Internal consistencies range from .69 to .74. Study 2 establishes discriminant validity by demonstrating that the CWMS Dysregulation and Coping subscales differentiated, in the expected directions, between a group of children (n = 27) with DSM-IV anxiety diagnoses and a control group of children with no psychological disorders.     

Subscales of the Barratt Impulsiveness Scale differentially relate to the Big Five factors of personality

The place of impulsiveness in multidimensional personality frameworks is still unclear. In particular, no consensus has yet been reached with regard to the relation of impulsiveness to Neuroticism and Extraversion. We aim to contribute to a clearer understanding of these relationships by accounting for the multidimensional structure of impulsiveness. In three independent studies, we related the subscales of the Barratt Impulsiveness Scale (BIS) to the Big Five factors of personality. Study 1 investigated the associations between the BIS subscales and the Big Five factors as measured by the NEO Five‐Factor Inventory (NEO‐FFI) in a student sample (N = 113). Selective positive correlations emerged between motor impulsiveness and Extraversion and between attentional impulsiveness and Neuroticism. This pattern of results was replicated in Study 2 (N = 132) using a 10‐item short version of the Big Five Inventory. In Study 3, we analyzed BIS and NEO‐FFI data obtained from a sample of patients with pathological buying (N = 68). In these patients, the relationship between motor impulsiveness and Extraversion was significantly weakened when compared to the non‐clinical samples. At the same time, the relationship between attentional impulsiveness and Neuroticism was substantially stronger in the clinical sample. Our studies highlight the utility of the BIS subscales for clarifying the relationship between impulsiveness and the Big Five personality factors. We conclude that impulsiveness might occupy multiple places in multidimensional personality frameworks, which need to be specified to improve the interpretability of impulsiveness scales.     

Coping with the loan transition in professional association football

The present study generated a qualitative examination of male professional football players’ experiences of stress during the loan transition using the Demand Resources and Individual Effects (DRIVE) Model. Purposeful sampling was used to recruit participants (M age = 23; SD = 2.5) from various Premier League (n = 2), Championship (n = 8), and League (n = 1) clubs across the UK who have experienced a loan to another club. Guided by a critical realist philosophical orientation, semi-structured interviews were deductively developed based upon the DRIVE model to stimulate contextual discussion about the pre-transition resources (e.g. organizational support), perceived transition demands (e.g. performance pressure) and appraisals. Finally, players were asked to discuss their strategies for coping (e.g. situational coping) with loan demands and if they deemed this coping to be effective. Braun and Clarke’s (2013) thematic content analysis was utilised. Deductive thematic analysis was used to identify and evidence themes that were articulated in relation to the demands experienced, appraisals associated with such demands, and the coping strategies used to manage these demands. An inductive approach was used to code sub-themes from the data, on the basis of players’ specific experiences that had not yet been exemplified in the existing literature. This study presented loan transition demands (performance and organizational), contextual individual differences (situational coping, dispositional coping, and protective factors) and loan resources (transition preconditions and during loan) that may assist individuals’ performance and well-being. Practitioners would be advised to work with players on facilitating pre-transition resources and identify perceived demands they consider important to their transition process. Future research should seek to explore the loan transition within elite female football.     

Match performance and physical capacity of players in the top three competitive standards of English professional soccer

The aim of this study was to compare the match performance and physical capacity of players in the top three competitive standards of English soccer. Match performance data were collected from players in the FA Premier League (n = 190), Championship (n = 155) and League 1 (n = 366) using a multiple-camera system. In addition, a selection of players from the Premier League (n = 56), Championship (n = 61) and League 1 (n = 32) performed the Yo-Yo intermittent endurance test level 2 (Yo-Yo IE2) to determine physical capacity. Players in League 1 and the Championship performed more (p < .01) high-intensity running than those in the Premier League (Effect Size [ES]: 0.4–1.0). Technical indicators such as pass completion, frequency of forward and total passes, balls received and average touches per possession were 4–39% higher (p < .01) in the Premier League compared to lower standards (ES: 0.3–0.6). Players also covered more (p < .05) high-intensity running when moving down (n = 20) from the Premier League to the Championship (ES: 0.4) but not when players moved up (n = 18) standards (ES: 0.2). Similar Yo-Yo IE2 test performances were observed in Premier League, Championship and League 1 players (ES: 0.2–0.3). Large magnitude relationships (p < .05) were observed between Yo-Yo IE2 test performances and the total and high-intensity running distance covered in both Championship (r = .56 and .64) and Premier League matches (r = .61 and .54). The data demonstrate that high-intensity running distance was greater in players at lower compared to higher competitive standards despite a similar physical capacity in a subsample of players in each standard. These findings could be associated with technical characteristics inherent to lower standards that require players to tax their physical capacity to a greater extent but additional research is still required to confirm these findings.     

Comparing Job Applicants to Non‐applicants Using an Item‐level Bifactor Model on the HEXACO Personality Inventory

The present study evaluated the ability of item‐level bifactor models (a) to provide an alternative explanation to current theories of higher order factors of personality and (b) to explain socially desirable responding in both job applicant and non‐applicant contexts. Participants (46% male; mean age = 42 years, SD = 11) completed the 200‐item HEXACO Personality Inventory‐Revised either as part of a job application (n = 1613) or as part of low‐stakes research (n = 1613). A comprehensive set of invariance tests were performed. Applicants scored higher than non‐applicants on honesty‐humility (d = 0.86), extraversion (d = 0.73), agreeableness (d = 1.06), and conscientiousness (d = 0.77). The bifactor model provided improved model fit relative to a standard correlated factor model, and loadings on the evaluative factor of the bifactor model were highly correlated with other indicators of item social desirability. The bifactor model explained approximately two‐thirds of the differences between applicants and non‐applicants. Results suggest that rather than being a higher order construct, the general factor of personality may be caused by an item‐level evaluative process. Results highlight the importance of modelling data at the item‐level. Implications for conceptualizing social desirability, higher order structures in personality, test development, and job applicant faking are discussed.

Effects of exposure to muscular and hypermuscular media images on young men's muscularity dissatisfaction and body dissatisfaction

This study examined the effects of exposure to muscular and hypermuscular media images on young men's body images, and the moderating roles of baseline body dissatisfaction (BD) and muscularity dissatisfaction (MD). Men (M age = 21.9, SD = 2.8) were exposed to pictures of muscular (n = 34) or hypermuscular (n = 29) male physiques throughout a 30-min health seminar. In support of the study hypotheses, higher levels of baseline BD and MD were associated with greater post-seminar BD and MD. In addition, MD moderated the effects of the exposure conditions on BD; greater baseline MD was associated with greater post-seminar BD, but only among men who viewed the muscular images. These results speak to the importance of pre-existing muscularity concerns in determining men's reactions to muscular physique images, and suggest that exposure to the media ideal of muscularity, and not muscularity per se, elicits body dissatisfaction in men with pre-existing muscularity concerns.     

From childhood to senior professional football: A multi-level approach to elite youth football players’ engagement in football-specific activities

ObjectivesThe main aim of this study was to identify the development of engagement in football-specific activities of elite youth association football (soccer) players who have made the transition to senior professional status or not.DesignComparative research design.MethodData were collected from all elite youth players (N = 745) within the age-range of 14–21 years from all Norwegian Premier League clubs, using a retrospective questionnaire. A within elite-group comparison of players who had obtained a senior professional contract or not was conducted by using multi-level modeling (n = 491).ResultsThe results showed that although the professional players reported to have accumulated more overall practice hours than non-professionals from ages 6 to 19 years, none of these differences were significant. The professional players reported to have accumulated significantly more hours in play and coach-led practice at the youngest age categories. No significant differences were identified at older age categories or for other types of football-specific practice at any age.ConclusionsDifferences in performance attainment may be due to variation in the amount and types of football practice at the earliest years of participation, but may also be related to other factors than the number of hours spent in certain football-specific activities. We argue that implementation of multi-level modeling represents an important progression within practice history research, and is necessary to account for the actual individual’s development over time in addition to identify how different variables may affect the developmental process.     

Dynamic vision training transfers positively to batting practice performance among collegiate baseball batters

A growing body of evidence demonstrates visual, perceptual, and oculomotor abilities contribute to batting performance in baseball and there is interest in whether training such abilities can transfer positively to batting performance. The current study tested this question through a pre-registered, randomized, and placebo-controlled intervention, conducted with 24 collegiate baseball players at two NCAA Division 1 universities. Athletes were randomized to receive either dynamic vision training consisting of stroboscopic, anticipatory timing, and eye quickness drills, or placebo drills stylized after control procedures in previous vision therapy studies. Generalized near-transfer was tested via a digital visual-motor task battery (n = 20), while sports-specific intermediate and far transfer of training were evaluated through instrumented batting practice metrics (n = 14) and box score performance in NCAA-sanctioned games (n = 12), respectively. The effects of training group were tested on these outcome measures while controlling for covariates such as pre-training expectations and site. Participants averaged 8.50 hours of training with no significant group differences in training adherence, expectations, or baseline assessments. ANCOVA revealed no group differences in measures of visual-motor skills or NCAA game statistics. However, batting practice demonstrated significant improvements in launch angle (p = 0.002, Cohen’s d = 0.74) and hit distance (p < 0.001, Cohen’s d = 0.70) for the active training cohort relative to the placebo control. This controlled and pre-registered pilot study therefore provides preliminary evidence that vision training may improve batting practice performance, creating new opportunities for the transfer of skill training and warranting further study.
