The Kinematic and Kinetic Development of Sprinting and Countermovement Jump Performance in Boys

Abstract

Background: The aim of the study was to examine the kinematics and kinetics of sprint running and countermovement jump performance between the ages of 8-9, and 11-12 years old boys in order to understand the developmental plateau in performance. Methods: 18 physically active boys (Age: 10.1 ± 1.6), in an under 9 years old (U9) and an under 12 years old (U12) group performed 15 m sprints and countermovement jumps. A 3D motion analysis system (200 Hz), synchronized with four force platforms (1,000 Hz), was used to collect kinematic and kinetic data during the first stance phase of the sprint run and the countermovement jump.

Acceleration Capacity and Vertical Jump Performance Relationship in Prepubertal Children

“…This relationship between sprint and jump abilities in children highlights the importance of lower body strength and power output for these two actions. A recent article [49] has already suggested that inter-individual differences in children's sprint performance could be linked to the ability to produce force, and not to a technical difference. This idea is supported by some studies that have demonstrated the positive effect of strength development on sprint and jump performance.…”
