Previous research exploring the relationship between muscle dysmorphia, drive for muscularity, and disordered eating behaviors in relation to personality characteristics, particularly narcissism, has yielded interesting, though often conflictual, results. The current study attempts to further explore these relationships through assessing muscle dysmorphia, drive for muscularity, and disordered eating in relation different facets of narcissism: grandiose and hypersensitive. Participants for the current study included 173 male students that were recruited via departmental Study Board. Participants completed demographic information, the Narcissistic Personality Inventory-40, the Hypersensitive Narcissism Scale, the Muscle Dysmorphia Questionnaire, the Drive for Muscularity Scale, and the Eating Attitudes Test-26. Results were indicative of a positive relationship between muscle dysmorphia symptomotology and hypersensitive narcissism, as well as positive relationships between drive for muscularity and facets of grandiose narcissism. Results also indicated that disordered eating, as an individual construct, was not related to narcissism. Results provide direction for the further study of the dimensional structure of the construct of narcissism, as well treatment implications for those suffering from muscle dysmorphia.

Published Article / A descriptive observational study was conducted among undergraduate medical students to determine whether the knowledge of Anatomy influenced their body image perceptions. The perception of some students regarding their body image and appearance was different after the course, and also their view of other peoples' bodies. The findings of the study support the literature that males are more concerned with muscularity and developing muscles, whereas females are more preoccupied with thinness. The study showed that a course in Anatomy might have an influence on students' perceptions of their own and other peoples' physical appearance.

Historically, cultural pressures to be thin and their effects on women (e.g., body dissatisfaction, disordered eating) have received considerable attention from researchers and clinicians. However, acknowledgement of cultural pressures on men to be muscular and lean is much more recent, as are men's increasing rates of body dissatisfaction and body-changing behaviors (i.e., drive for muscularity, nutritional supplement/steroid use, excessive weightlifting). The increasing presence of idealized lean, muscular men in the media may be one of the influences on men's increasing body dissatisfaction, although studies examining the relationship between viewing these idealized portrayals and men's drive for muscularity/body satisfaction have yielded mixed results. Additionally, individual difference factors that may influence this relationship need further investigation. The purpose of this study was to address these two areas of research. It was hypothesized that men exposed to idealized television portrayals of lean, muscular men would report higher muscle/body fat dissatisfaction and drive for muscularity attitudes scores compared to men exposed to television portrayals of average-looking men. Additionally, it was predicted that men who report higher perfectionism, neuroticism, and drive for muscularity, and who more strongly endorse traditional attitudes about the male role, would report higher drive for muscularity and muscle/body fat dissatisfaction at post-test compared to men who report lower perfectionism, neuroticism, and drive for muscularity, and who are less concerned with traditional male role norms. Two-hundred-thirty-five undergraduate men at The University of Texas at Austin participated in the online study. During Phase 1, participants completed questionnaires assessing drive for muscularity, muscle/body fat dissatisfaction, perfectionism, neuroticism, and attitudes about the male role. One week later, they were randomly assigned to either the muscular-image or average-image group to complete Phase 2. After viewing television commercials corresponding with their experimental groups, participants again completed all pre-test measures. Results suggested that men in the average-image group (rather than the muscular-image group) with high drive for muscularity experienced greater body fat dissatisfaction than men with low drive for muscularity. Interesting findings regarding the relationships among perfectionism, neuroticism and drive for muscularity/body dissatisfaction also emerged. Implications of the study, strengths, limitations and suggestions for future research are discussed. / text

Research has shown that collegiate female athletes are oftentimes faced with negotiating meanings of their femininity and their athleticism. Athleticism has traditionally been equated with masculinity, and to be a collegiate athlete requires certain levels of skill, experience, and athletic ability. Therefore, female collegiate athletes are conflicted with managing their identities in order to avoid accusations of their sexuality, which often results in being labeled as deviant. A primary indicator of athleticism is muscularity, which is also considered a masculine trait. In order to stay within gender boundaries, female athletes may go above and beyond to emphasize their femininity, or they may hold back on performance and training to avoid a muscular physique. An area of collegiate athletics that has become increasingly important is the strength and conditioning coach and weight room. These coaches are responsible for training athletes in power and speed development to enhance sport performance and prevent injury. Research has shown, however, that the weight room and activity of lifting weights has not been deemed socially appropriate for women. The purpose of this study was to understand first, how do Division-I female athletes negotiate their femininity and muscularity within the strength and conditioning environment? Second, is there a difference in femininity and muscularity negotiations and management between underclassmen female collegiate athletes and upperclassmen female collegiate athletes? Finally, what aspects of the weight room influence the negotiations of femininity and muscularity among female collegiate athletes? To gain a rich understanding of how female athletes negotiate their femininity with muscularity in the strength and conditioning environment, a qualitative methodology was used. Semi-structured, in-depth interviews were conducted with 14 athletes, from 7 different sports, at a Midwestern Division-I university. Using a critical feminist interactionist theoretical framework, this study found that female collegiate athletes negotiate their meanings of muscularity and femininity in the strength and conditioning environment. Athletes viewed it necessary to place boundaries on their muscularity in regards to size, preferring the `toned' physique. All athletes acknowledged a positive impact on their sport performance, yet some athletes admitted to holding back during strength and conditioning sessions. Others believed that the weight lifting program was not threatening to their muscularity, but explained they would hold back if it did have a `bulking' effect. Finally, some athletes performed additional cardiovascular training to reduce body size. Additional findings suggest that the weight room environment is influential for the female athletes. The public weight room was described as a gendered space that was intimidating. In contrast, the collegiate weight room was a place that was welcoming to the female athletes. The strength and conditioning coach played an important role to the environment and the female athletes. Concluding results show that inconsistent with previous research, there were no consistent findings in attitude or behavior differences between underclassmen and upperclassmen athletes.

Orientador: Robson Francisco Carvalho / Resumo: A caquexia é uma síndrome metabólica complexa que frequentemente acomete pacientes portadores de neoplasia maligna em estádio clínico avançado. Caracteriza-se pela perda de massa muscular (com ou sem perda de tecido adiposo), a qual não pode ser completamente revertida por suporte nutricional. As vias moleculares responsáveis pela caquexia não estão completamente esclarecidas, entretanto, os avanços em estudos genômicos, transcriptômicos e proteômicos no câncer tem auxiliado na compreensão da importante relação entre o secretoma tumoral com alterações em órgãos e tecidos adjacentes ou distantes do tumor. Evidências têm demonstrado que componentes do secretoma do ambiente tumoral, incluindo citocinas pró-inflamatórias, possuem um papel fundamental no desenvolvimento de alterações metabólicas que resultam em sarcopenia (perda de função e massa muscular) em pacientes caquéticos. A perda de massa muscular é considerada um importante fator prognóstico de caquexia para pacientes com carcinomas de pulmão de células não pequenas (CPCNP) e, portanto, a avaliação de área muscular utilizando-se de tomografias computadorizadas (CTs) tem sido utilizada com grande eficácia para determinar a sobrevida e a presença de caquexia e sarcopenia nesses pacientes. Portanto, a hipótese desse trabalho é que a integração de dados clínicos e prognósticos, área dos músculos peitorais obtidas por CTs e perfil transcricional tumoral permitirá identificar potenciais biomarcadores de caquexia no secretoma d...

The molecular pathways of cancer cachexia are not completely known. The advances in genomic, transcriptomic and proteomic studies in cancer have helped in understanding the relationship of the tumor's secretome with changes in organs and tissues adjacent to or distant from the tumor. Evidences show that components of the tumor secretome, including pro-inflammatory cytokines, play a key role in metabolic alterations that result in sarcopenia (loss of muscle mass and function) of cachectic patients. Loss of skeletal muscle mass is important prognostic factor for cachexia in patients with non-small cell lung cancer (NSCLC), thus the evaluation of muscular area using computed tomography (CT) has been effective in determine survival and the presence of cachexia and sarcopenia in these patients. Therefore, our hypothesis is that the integration of clinical and prognostic data, pectoralis muscle area obtained by CTs, and tumor transcriptional profile will allow the identification of potential biomarkers of cachexia in the secretome of non-small cell lung carcinomas. To do this, 89 CTs from patients with NSCLC, available on the TCIA (The Cancer Imaging Archive) platform were used to measure the pectoralis muscle area, and to select patients with...

Historically disordered eating research has been gendered with models focusing on women’s pursuit of a thin ideal, as well as men’s attempts to obtain a muscular ideal. The motivations to achieve these ideals are called the drive for thinness (DT) and drive for muscularity (DM). More recently, a cultural shift has been noted in that ideal bodies are converging across sexes to a lean ideal, with the associated motivation being labeled the drive for leanness (DL). As DL is a nascent construct, little is known about its relationships with DT and DM, or if it predicts or is predicted by the same variables that are associated with DT and DM. This study aimed to expand what is known about DL in four ways: 1) ascertain the uniqueness of DL from DT and DM; 2) explore whether DL is sex neutral; 3) investigate the extent to which DL is more or less adaptive than DT and/or DM in terms of health-related outcomes; and 4) explore associations between DL and established predictors from sociocultural models of disordered eating. Analyses evidenced support for DL’s distinctiveness from DT and DM, partial support for DL’s sex neutrality, partial support discerned via relationships with health-related outcomes for DL’s adaptive nature in comparison to DT or DM, and support for DL’s relationships with sociocultural predictors being similar to that seen between these predictors with DT and DM. This study adds to the literature by broadening what is known about DL’s uniqueness, sex neutrality, adaptive nature, and sociocultural fit in relation to the other drives within a theory based framework, providing a potential basis for future DL model building and research in general.

Over the past decade, the study of male body image has increased considerably and substantial levels of body discontent among males have been reported. Accompanying this dissatisfaction is a rise in the documentation of the Drive for Muscularity (DFM), or the desire for increased lean muscle mass, in men. The current study had three objectives. The first was to identify theoretical variables associated with the DFM. The second was to examine body image evaluation and investment in relation to the DFM. The third was to explore the DFM and psychological well-being. Two-hundred fourteen men completed the study and multiple regressions were carried out to examine the various relations. Awareness and internalization of the male body ideal and universalistic social comparison accounted for 35% of the variance in the DFM. Body image investment, but not evaluation, accounted for 26% of the variance in the DFM. Regarding psychological well-being, the DFM accounted for an additional 23% of the variance in muscle pathology after controlling for levels of depression and self-esteem. Other notable findings included mens self-reported intentions to use potentially unhealthy body change strategies to increase size and musculature in the future, and statistically significant associations between the DFM and self-esteem, social physique anxiety, and general worry. These results contribute to the growing literature on male body image and the implications for clinical practice with men presenting with body dissatisfaction are discussed.

This study examined relationships among self-esteem, media internalization, sexual orientation, and ethnicity in predicting drive for muscularity in a diverse group of men (N = 217) who work out in gyms. Investigations examined media internalization and sexual orientation as moderators of the relationship between self-esteem and drive for muscularity. Additional analyses examined media internalization as a moderator of the relationships between a) sexual orientation and drive for muscularity and b) ethnicity and drive for muscularity. Standardized questionnaires were utilized to assess drive for muscularity, media internalization, self-esteem, sexual orientation, and ethnicity. While lower self-esteem predicted greater drive for muscularity, neither media internalization nor sexual orientation were significant moderators of this relationship. However, media internalization mediated the relationships between sexual orientation and drive for muscularity and between ethnicity and drive for muscularity. Findings suggest that the internalization of ideal muscularized images explain demographic differences in the drive to be more muscular.
