title: Extended Reference Values for the Muscle Power Sprint Test in 6- to 18-Year-Old Children.
abstract: OBJECTIVE
  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.
