- Abstract
The article discusses the accuracy of momentary time sampling. Moderate levels of physical activity have been shown to enhance physical and mental health while producing positive changes in one's quality of life. Experts believe physical education in schools is an investment in our society's economic and healthcare future. As part of the paradigm shift in physical education from a product to a process orientation, individuals within the physical education and health professions have collaborated to emphasize what has been termed health-related physical education, which promotes regular participation in physical activity. System for Observing Fitness Time Instruction (SOFIT) has been validated for the purpose of collecting data on human physical activity behavior. Duration recording (DR) offers a complete record of the temporal dimension of behavior and serves as a measure to compare estimates of behavior. One such estimate technique used in SOFIT's protocol is called momentary time sampling. Unlike DR, MTS provides an estimate of behavior by taking samples of behavior during an event at the end of each observation interval. The measured targeted behavior is scored as having occurred if it was present at the end of the observation interval.
