Previous research has used cluster analysis to examine how social physique anxiety (SPA) combines with motivation in physical education. This study utilized a more advanced analytic approach, latent profile analysis (LPA), to identify profiles of SPA and motivation regulations. Students in grades 9-12 (N = 298) completed questionnaires at two time points assessing SPA and motivation regulations, psychological needs, enjoyment, effort, and characteristics of physical education peers. LPA identified four profiles representing "Autonomous" (13.4%), "Average" (39.3%), "Low Autonomous" (25.2%), and "Autonomous and Introjected" (22.1%). Profiles were replicated at a second time point, and evidence of profile measurement invariance across gender was found. A multivariate analysis of variance (MANOVA) showed profile differences. The model-based analytic approach to identify profiles of SPA and motivation regulations differed from cluster analysis profiles. The profiles were not driven by SPA, rather autonomous motivation is the dominant factor associated with physical education motivational experiences.
