The Physical Performance Across the Lifespan (PALS
) Study is a collaboration between the Duke Pepper Center
and the MURDOCK Study
. Briefly, the PALS Study explores dimensions of health, function, behavior, and physiologic characteristics in a cohort of 1,000 adults aged 30-90+, with oversampling across the older decades. The PALS study includes a comprehensive assessment battery at two time-points: baseline and 2-year follow-up, which concluded in 2018.
