As a scarcely investigated factor, age showed to be a strong negative predictor for drive for muscularity. Increased age was related to lower global, attitudinal, and behavioral facets of drive for muscularity. It is possible that, over time, other aspects of life, such as career, financial resources, or family become more important than physical appearance, resulting in a reduction of drive for muscularity. Alternatively, the desired level of muscularity might be attained and the initial need be satisfied. The relation of age and drive for muscularity could be moderated by different degrees of internalization of media body ideals. Current data support Grieve’s (2007) notion that the muscular ideal appears to be very salient for adolescents and college men, but might be less important to older samples. This is consistent with Stratton et al. (2015), who found men older than college age to be less dissatisfied by bodily comparison. Self-esteem and body dissatisfaction could also be interacting with age, since it has been shown, that in adult life with higher age, both, self-esteem (Robins et al., 2002) and body satisfaction (Tiggemann and McCourt, 2013) are rising. Future research, especially longitudinal studies, are required to further examine the relationship between age and drive for muscularity, as well as developmental and hormonal influences in younger age.
