BACKGROUND Reduced push-off intensity during walking is thought to play an important role in age-related mobility impairment. We posit that an age-related shift toward shorter plantarflexor operating lengths during walking functionally limits force generation, and thereby the ability of those muscles to respond to increased propulsive demands during walking. RESEARCH QUESTION To determine whether gastrocnemius muscle fascicle lengths during normal walking (1) are shorter in older than young adults, and (2) correlate with one's capaci
