The Aging and Population Health Lab (APHL) studies mobility and aging, including the prevention, etiology, and management of age-related mobility limitations, as well as the promotion of mobility through physical activity. We have areas of concentration in physical activity, fall and injury prevention, and walking energetics and fatigability. We are currently testing interventions to reduce fall-related injuries, finding out how tailored exercise programs affect the energy requirements of walking and fatigability, and piloting new approaches to help older adults adhere to their physical activity goals. Our research is embedded in a framework that supports translation of insights into actions. Research in the Lab incorporates techniques from epidemiology and biostatistics, including clinical trial design, causal inference, longitudinal cohort studies, knowledge synthesis, and meta-analysis. We also conduct more traditional laboratory experiments. Ultimately, our research seeks to identify and disseminate effective strategies for successful population aging through maintenance of mobility and functional autonomy.
