Abstract

The mechanisms responsible for increased metabolic cost of walking in older adults are poorly understood. We recently proposed a theoretical premise by which age-related reductions in Achilles tendon stiffness (k

Research summary

The paper investigates the relationship between Achilles tendon stiffness and the metabolic cost of walking in older adults, which is relevant to understanding age-related physiological changes. However, while it contributes to the knowledge of how aging affects mobility, it does not address the root causes of aging or propose solutions for lifespan extension or age-related diseases. Thus, its impact is limited to solid research without significant implications for the broader field of longevity.
