The aim of this study was to determine pedometry steps per minute (SPM) cutscores that accurately quantify physical activity (PA) time in first- through fourth-grade physical education. A total of 257 participants were grouped in two data pools, first- and second-grade (n = 126), and third- and fourth-grade (n = 131). Systematic observation was the PA criterion instrument and pedometry was the predictor instrument.

- - The study aimed to establish a standard for measuring steps per minute to quantify how much time first- and second-graders spend in moderate to vigorous physical activity (MVPA) during physical education classes.
- - Researchers analyzed data from 45 lessons, using a combination of pedometry and systematic observation to find the optimal steps per minute that indicated students were engaged in MVPA for at least 33.33% of a 30-minute class.
- - Results showed a strong correlation (r = 0.74-0.86) between pedometer data and observations, identifying a cut point of 60-63 steps per minute as an effective measure for MVPA, making pedometry a promising tool for monitoring physical activity in schools.*
