          Abstract

          Abstract The aim of this study was to analyze the influence of coach’s leadership style on eating disorders (ED) in female volleyball athletes. This is a prospective study with 73 participants of sub-17 state of Pernambuco Championship. The Eating Attitudes Test was applied to evaluate ED. The perception of the coach’s leadership style was evaluated with Leader Sport Scale subscales. Triceps and subscapular skinfolds were measured to estimate body fat percentage. The findings showed no influence of “Training-Instruction” on ED (F(3, 70)=45.02; R2=0.12; p=0.34). The “Social Support” subscale showed statically significant influence on ED (F(4, 69)=59.77; R2=-0.16; p=0.02). However, the results indicated no statically significant relationship of “Reforce” subscale with ED (F(5, 68)=52.40; R2=0.13; p=0.17). The “Democratic” subscale so showed no influence on ED F(6, 67)=49.08; R2=0.10; p=0.21). Finally, the “Autocratic” subscale showed influence on ED (F(7, 66)=67.23; R2=0.18; p=0.01). We concluded that the coach’s leadership style (social support and autocratic) influenced the adoption of DEB in young female volleyball athletes.

          Resumo O objetivo da investigação foi analisar a influência do estilo de liderança do treinador sobre os comportamentos de risco para os transtornos alimentares (CRTA) em atletas de voleibol do sexo feminino. Trata-se de uma investigação com delineamento prospectivo (follow-up de 3 meses) desenvolvida com 73 atletas participantes do campeonato Pernambucano da categoria sub-17. Para avaliar os CRTA foi aplicado o Eating Attitudes Test. A fim de se avaliar a percepção do estilo de liderança do treinador, foram utilizadas as subescalas da versão percepção-atleta da Escala de Liderança no Desporto. Foram aferidas as dobras cutâneas triciptal e subescapular para a estimativa do percentual de gordura corporal. Os achados não revelaram influência da subescala “Treino-Instrução” sobre os CRTA (F(3, 70)=45,02; R2=0,12; p=0,34). A subescala “Suporte Social” demonstrou influência estatisticamente significante nos CRTA (F(4, 69)=59,77; R2=-0,16; p=0,02). Todavia, os resultados não indicaram relação estatisticamente significante da subescala “Reforço” com os CRTA (F(5, 68)=52,40; R2=0,13; p=0,17). Do mesmo modo, a subescala “Democrático” também não demonstrou influência sobre os CRTA (F(6, 67)=49,08; R2=0,10; p=0,21). Por fim, a subescala “Autrocrático” apontou influência sobre os CRTA (F(7, 66)=67,23; R2=0,18; p=0,01). Concluiu-se que o estilo de liderança do treinador (suporte social e autocrático) influenciou na adoção de CRTA em jovens atletas de voleibol do sexo feminino.

          Disordered eating in male athletes: a meta-analysis.

          We examined the propensity for male athletes to exhibit symptoms of disordered eating. Using meta-analytic techniques, we examined overall effect size, individual effect sizes for specific sport types, standard of athletic competition and diagnostic tools from 31 studies. When all studies were considered as a homogeneous group, male athletes did not have symptoms of disordered eating that were significantly different from non-athletic controls. However, significant moderator effects emerged for sport type and measurement: (a) wrestling reported a greater incidence of disordered eating; and (b) studies that reported data from the Eating Attitudes Test yielded a significantly greater incidence of disordered eating in male athletes compared to non-athletes. Although some sports seem to present a higher risk of disordered eating compared to others, the effects are weak and heterogeneous. We make suggestions for the development of the research area, which has been severely hampered by the diagnostic tools that have been available for the study of men.

            A socio-sports model of disordered eating among Brazilian male athletes.

            The objective of this study was to develop a socio-sports model of disordered eating (DE) in Brazilian male athletes. Three hundred and twenty one athletes over 12 years of age from 18 different sports modalities were investigated. The Eating Attitudes Test (EAT-26) was applied to evaluate DE. The Body Shape Questionnaire (BSQ) was used to evaluate athlete dissatisfaction with body fat levels. The Muscularity Concern subscale of the Drive for Muscularity Scale (DMS) was used to evaluate athlete dissatisfaction with muscularity levels. To investigate the influence of sociocultural factors on body image, the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) was applied. Body fat was estimated by skinfold measurement. Demographic data were collected (competitive level and training regimen). Structural equation modelling was conducted to analyse the relationships between research variables and the factors that mediate them. The results indicated that the sociocultural factors and body fat dissatisfaction adhered to socio-sports model of DE (X(2) = 18.50, p = .001, RMSEA = .069, GFI = .97, AGFI = .91, TLI = .93). The BSQ accurately predicted the relationship between SATAQ-3 and EAT-26 (R(2) = .08, p = 0.001) scores. A direct relationship between the SATAQ-3 and EAT-26 (R(2) = .07, p = 0.01) and BSQ (R(2) = .10, p = 0.001) scores was identified. No relationship was found between structural equation model and Muscularity Concern (R(2) = .02, p = 0.14), competitive level (R(2) = .01, p = 0.19), training regimen (R(2) = .03, p = 0.11) or body fat (R(2) = .02, p = 0.14). The results suggest that sociocultural factors and body fat dissatisfaction follow the socio-sports model of DE in Brazilian male athletes.

              Weight perception in female athletes: associations with disordered eating correlates and behavior.

              Although weight perception is associated with disordered eating correlates and unhealthy eating behavior, it is unclear whether these associations exist in specific female populations at greater risk of disordered eating (i.e., athletes). The aim of this study was to examine associations between weight perception and disordered eating correlates (perfectionism and social physique anxiety (SPA)) and eating behavior in female athletes. Measures of perfectionism (positive and negative), SPA, weight perception and disordered eating were completed by 136 female elite athletes. Athletes with overweight perceptions reported greater negative perfectionism, higher SPA and more disordered eating behavior than female athletes with normal-weight perceptions. Overweight perceptions are, therefore, an additional factor to consider in the relationship between perfectionism, physique anxiety and disordered eating in female athletes.
