Abstract

The reliability and validity of horizontal jump (HJ) kinetic measures was assessed for six female national-class track sprinters aged 15-18 years. Each sprinter performed three 10 m sprints, as well as five standing HJs and five reactive HJs from a 45 cm drop. Two Kistler force platforms (1000 Hz) covered with Mondo track surface recorded the HJ ground contact kinetics and an aluminium measuring tape was used to record HJ distance. Statistical measures included the intra-class coefficient and coefficient of variation to determine reliability of the measures. Linear regression analysis between sprint performance and the HJ measures was employed to assess validity. The standing explosive HJ test was revealed to be valid and reliable in female junior sprinters. The kinetic measures were superior to traditional field measures of jump distance.
