Extended Reference Values for the Muscle Power Sprint Test in 6- to 18-Year-Old Children

Abstract

Purpose: The first aim was to extend the reference values and curves of the Muscle Power Sprint Test (MPST) in children with typical development. The second aim was to examine test/retest and intertester reliability of the MPST. Methods: A total of 683 children aged 6 to 18 years (mean = 11.9 ± 3.8 years) were tested on the MPST. Test/retest reliability was examined in 71 children and intertester reliability in 77 children. MPST scores were merged with existing values and transformed into height-related normative reference curves. Results: Sex-specific MPST curves were generated for children aged 6 to 18 years. Test/retest reliability was good (intraclass correlation coefficient = 0.90) and intertester reliability was excellent (intraclass correlation coefficient = 0.97). Conclusions: New and more complete MPST normative reference values and curves for children from 6 to 18 years old are now available. The MPST is easy and reliably performed by clinicians.
