  "abstract": "Introduction: Follow-along exercise and health short videos provide the public with convenient exercise references, yet their efficacy statements, applicability conditions, and risk information warrant attention.\n\nMethods: Using a sample of 250 videos from Douyin, this study employed a diagnostic evaluative content analysis to examine efficacy claims, applicability boundaries, risk warnings, and professional justification. Intercoder reliability was assessed, and comparisons were conducted across content types.\n\nResults: The proportions of videos meeting the severe expressive-problem criterion (score 3) were 36.8% for risk warnings, 34.4% for efficacy claims, and 25.6% for applicability boundaries, compared with 2.0% for professional justification. A total of 54.4% of the videos exhibited at least one score-3 problem, and 36.0% exhibited two or more. Content type was statistically associated with score-3 distributions for Dimensions B, C, and D (all Holm-adjusted p < 0.001), whereas Dimension E did not reach significance ( p = 0.369). Fat-loss and body-shaping videos were more likely to show efficacy-claim problems, while pain-relief and general rehabilitation videos were more likely to show problems with applicability boundaries and risk warnings.\n\nDiscussion: Governance of follow-along content should be tailored to specific contexts, improving efficacy statements, applicability conditions, risk warnings, and the articulation of professional justification.",
