Association between estimated cardiorespiratory fitness and arthritis in older adults: evidence from four large cohorts

Key Points

• Arthritis prevalence decreases with increased cardiorespiratory fitness, indicating a potential protective effect.
• Specifically, higher fitness levels correlate with lower arthritis symptoms, with a notable reduction observed.
• Observational analysis across four large cohorts highlights the importance of maintaining cardiorespiratory fitness.
• Implications suggest that improving physical activity levels may reduce arthritis risk, enhancing overall well-being.
