Associations Between Gait Variability and Metabolic Cost Across Different Aging and Functional Populations
DescriptionWalking efficiency is essential for maintaining mobility and independence, particularly as people age. However, the relationship between how people walk and how much energy walking requires is not fully understood across different populations. This study examines how these relationships differ between younger adults and older adults with reduced physical function. Using data from 64 participants, we analyzed walking patterns and metabolic energy use during overground walking. We evaluated three metabolic measures (peak, gross, and reserve cost) alongside spatial, temporal, and variability-based gait characteristics. Relationships between these variables were assessed using correlation analyses. Results revealed distinct patterns between groups. In younger adults, metabolic cost was primarily associated with timing and propulsion-related gait features, suggesting efficient coordination of movement. In contrast, older adults showed stronger associations between metabolic cost and gait variability and asymmetry, indicating that instability and inconsistent movement may increase energetic demand. These findings highlight an age-related shift in how walking efficiency is achieved. Understanding these differences can help inform targeted interventions, rehabilitation strategies, and assistive technologies aimed at improving mobility and reducing fatigue in aging populations.
