Men and muscularity research: a review (vol 8, 20, 2021)

Over the past 25 years, understanding males’ interest in and outcomes of muscularity has developed into a major area of study. Research has been fueled by the development of measures of both the attitudinal and behavioral aspects of a desire to increase muscularity. Our research purpose was to critically assess muscularity research. Using a database search, the ancestry approach, and searching key journals, we identified empirical refereed journal articles with men as participants published from 2000 to 2019 to serve as our data. Our analyses revealed several individual characteristics (e.g., perfectionism, holding to traditional masculine norms) and socio-cultural influences (e.g., media, verbal commentary) that fueled men’s desire to be muscular. In experimental research, exposure to muscular male ideal images has resulted in low body image scores for young men in investigations that utilized pre-test, post-test designs. In survey research, muscularity was positively related to several risky behaviors or behaviors that could become risky if taken to the extreme. Overall, the reviewed research was conducted in western countries and researchers primarily utilized non-probability samples of undergraduate men. Recommendations for future research are provided. © 2021, The Author(s).
