Faster walking linked to higher daily activity in older adults

A recent longitudinal study conducted by researchers at the University of Jyväskylä in Finland has found that physical activity levels decline significantly as people age, even among older adults who are otherwise in good physical condition. The investigation tracked participants over a four‑year period, measuring their physical activity energy expenditure (PAEE) through objective monitoring devices.

The results revealed an average reduction of roughly 17 % in PAEE across the cohort. This decline was consistent across various age groups and was not fully explained by changes in body weight or health status, suggesting that age itself may be a strong predictor of reduced activity. The researchers noted that the decrease occurred despite participants maintaining overall fitness, indicating that other factors—such as lifestyle changes, social engagement, or environmental barriers—might contribute to the drop in activity.

These findings underscore the importance of targeted interventions to sustain physical activity in older populations. By identifying the magnitude of decline and its persistence even among fit individuals, the study provides a benchmark for public health programs aimed at promoting active aging and mitigating the risks associated with sedentary behavior.
