Gender moderates the effect of exercise on anxiety sensitivity

A moderate to vigorous intensity exercise program is emerging as a promising strategy for reducing anxiety sensitivity (AS). Initial evidence suggests that the effects of exercise on mental health outcomes may vary as a function of gender, with men benefitting more than women. Building upon this evidence, the present study tested the hypothesis that the effect of exercise on AS would vary as a function of gender, such that the effect would be stronger for men than for women. We tested this hypothesis using the data from a published study (Smits, Berry, Rosenfield, et al., 2008). In this study, participants (N = 60) with elevated levels of AS were randomly assigned to a two-week exercise intervention [EX] or a waitlist control condition [WL]. Results revealed that males showed significantly greater initial AS reductions relative to females (following 1 week of exercise). However, these gender differences were no longer evident at the end of the intervention. Possible mechanisms for the observed findings and directions for future research are discussed.
