#workoutathome: How Instructions in the Captions of Fitfluencers' Posts Impact Adolescents' Body Satisfaction and Intention to Exercise

The present study examines how content of fitfluencers can be employed to improve body satisfaction and intention to exercise among adolescents. Specifically, this experimental study (N = 114 adolescents, age: 16-18) compares the effects of fitfluencer content with instructional captions that contain exercise or workout instructions (as a form of edutainment) with those of self-focused fitfluencer captions that emphasize the fitfluencer's appearance. These two types of captions are found to induce no significant differences in either body satisfaction or intention to exercise. In addition, there were no significant indirect effects via state appearance comparison or self-efficacy. The results do show that less state appearance comparisons increase body satisfaction, and that more self-efficacy increases body satisfaction and intention to exercise. The results suggest that instructions in fitfluencer captions do not differ from self-focused captions in their effects on body satisfaction and intention to exercise among adolescents.

Can Stereotype Threat and Lift Visual Messages Affect Subsequent Physical Activity? Evidence from a Controlled Experiment Using Accelerometers

This study investigated how visual messages conveying stereotype threat or lift influenced physical activity performance. Participants (N = 380) were exposed to a stereotype threat, lift, or control condition image and then engaged in a running task. Accelerometers recorded forward-backward movement, upward-downward movement, and sideways balance. Stereotype threat exposure increased state anxiety relative to the control condition. In addition, forward-backward movement was linked to state anxiety and participants' sex. Moreover, women exposed to stereotype threat who experienced increased state anxiety showed reduced forward-backward movement. Men exposed to stereotype lift displayed higher forward-backward movement. Additionally, stereotype threat visual message exposure increased sideways balance activity for women but not for men. Upward-downward movement was unaffected by stereotype threat or lift. We discuss theoretical and practical implications of how exposure to visual stereotypes can influence physical activity performance.
