Having valid and reliable methods for assessing physical activity levels is critical to understanding physical activity patterns. Direct observation is a widely used technique for obtaining contextually rich data on physical activity levels in physical education classes. One major limitation of direct observation is that it is time intensive. The use of digital video editing software programs may lessen the amount of time needed to gather the data. The purpose of this study was to compare the amount of time needed to obtain SOFIT (System for Observing Fitness Instruction Time) physical activity data using the traditional paper and pencil method and using SOFIT with Studio Code digital video editing software (Studio Code, Sportstec International, Camarillo, CA). Six second-grade classes (N = 23) were video taped and observed using both methods to gather SOFIT data. A stop watch was used to determine how long it took to gather the data and it was found that Studio Code took significantly less time (t = 4.91, p < .004) to gather SOFIT activity data than using the traditional paper and pencil method. Researchers who use direct observation may decrease the amount of time needed to gather data by using digital video software.
