Courtesy of: www.seb.org/class/53662-jazzercise Hypothesis When exercising in a mirrored environment… Participants with greater levels of social physique anxiety and lower levels of physical self-worth upon initial assessment will experience even poorer scores in these areas after exercising in a mirrored environment. Participants with low levels of social physique anxiety and higher levels of physical self-worth upon initial assessment will have no difference in social physique anxiety and physical self-worth when exercising in a mirrored exercise space. Participants who regularly exercise in mirrored environments will be less effected by the mirrored condition regardless of their self-concept levels.Methods Participants Participants Undergraduate students who are at least 18 years of age and physically healthy. Instruments PAR-Q (Thomas, Reading, & Shephard, 1992) to screen participants for physical ability to exercise. The Physical Self-Perception Profile (PSPP; Fox & Corbin, 1989) examines five aspects of physical self- worth. The Social Physique Anxiety Scale (SPAS; Hart, Leary, & Rejeski, 1989) measures participants’ perceptions and feelings about their physique/figure. The Godin Leisure–Time Exercise Questionnaire (LTEQ; Godin & Shephard, 1997) quantifies exercise over one week. Demographics Demographics Gender, age, weight, height, major, team or individual sport involvement, use/non-use of mirrors during exercise, and Jazzercise familiarity. Procedures Procedures Participants will complete the LTEQ, PSPP, and SPAS after signing the informed consent. They will then participate in two 30-minute Jazzercise classes within both mirrored & non-mirrored environments. Afterward, they will complete the PSPP and SPAS again. Analysis Analysis T-tests will be used to examine differences within subjects and across groups.References American College of Sports Medicine. (1997).
