Abstract: BACKGROUND: Pyroptosis is extensively involved in bone formation mediated by osteoblasts and bone resorption mediated by osteoclasts. Inflammatory factors released during pyroptosis contribute to bone metabolic imbalance. Exercise can inhibit pyroptosis and regulate the progression of bone metabolic disorders, which has become a research hotspot for preventing and treating such diseases.
OBJECTIVE: To summarize the regulatory role of pyroptosis in bone metabolic disorders and to elucidate the molecular mechanisms by which exercise-mediated pyroptosis improves these conditions.
METHODS: CNKI and PubMed were searched for relevant literature published from 1992 to 2025. The search terms were “exercise, pyroptosis, osteoporosis, osteoarthritis, rheumatoid arthritis, abnormal bone metabolism, osteoblasts, osteoclasts, bone marrow mesenchymal stem cells, osteocytes, chondrocytes” in Chinese and English, respectively. According to the inclusion and exclusion criteria, 80 articles were included for review.
RESULTS AND CONCLUSION: Pyroptosis plays a critical role in the pathogenesis of bone metabolic disorders. Recent studies have indicated that exercise, as a safe and effective non-pharmacological intervention, alleviates pyroptosis by suppressing inflammasome activation, inhibiting pyroptosis-related protein expression, modulating muscle factor cytokine secretion and reducing oxidative stress levels. These mechanisms collectively reduce bone resorption and enhance bone formation. However, current research on pyroptosis and bone metabolic disorders has limitations, and the specific signaling pathways and regulatory mechanisms by which exercise modulates pyroptosis in these diseases require further exploration.

Key words: pyroptosis, exercise, osteoporosis, osteoarthritis, rheumatoid arthritis, bone metabolic disorder
