Effects of Dance Interventions on Physical Function in Healthy Older Adults: A Systematic Review and 3-Level Meta-Analysis.

Dance serves as an effective nonpharmacological strategy for promoting healthy aging. Based on current evidence, public health policymakers should prioritize resource allocation toward the 70- to 75-year-old community-dwelling population. Regarding dance prescription design, we advocate for an 8-week baseline cycle to generate significant benefits and highlight the potential value of short-duration models (∼20 minutes) in enhancing adherence and improving function. However, given that this single-session duration falls below traditional exercise physiology recommendations, future research must further elucidate the optimal "dose-response" mechanism of dance; until its biological plausibility is established, generalizing this specific duration as a standard should be approached with caution.
