Relationship Between Cardiorespiratory Fitness, Weight Status, and Academic Performance: Longitudinal Evidence From 1 School District

Abstract

OBJECTIVES: We examined the longitudinal relationship between cardiovascular fitness (CRF) and academic performance (AP) among students in a diverse public school district. Furthermore, we determined whether the relationship between CRF and AP varied by student sociodemographic characteristics. METHODS: This study used data from 2005-2006 to 2008-2009. AP was assessed by Massachusetts Comprehensive Assessment System (MCAS) math (N = 1224) and English Language Arts (ELA) (N = 1248) z-scores. CRF was assessed by an age- and sex-adjusted 20-yard shuttle run (pass/fail). Multilevel growth models were used to estimate the relationship between MCAS z-scores and changes in grade, CRF, and weight status, controlling for student sociodemographic characteristics. RESULTS: Students who passed the fitness test performed better on MCAS tests (ELA:.159, p
