The problem of inadequate physical activity is extensive, and it affects over 50% of the population. Dr. Lapham served site PI for a 5-site national study to evaluate an assessment, Systematic Observation of Play and Recreation in Communities (SOPARC) to assess physical activity in parks using systematic momentary time sampling.
This project, funded by the National, Heart, Lung and Blood Institute grant number R01HL092569 validated SOPARC’s ability to measure total park use and population level energy expenditure, and determine reliability and validity of the self-report of physical activity in diverse public parks.
