Modelling / Simulation
The purpose of the current study was to evaluate countermovement jump biomechanical variables and to estimate peak power using different approaches in female children with dynamic knee valgus. Twenty-six female children, aged 10-14, with dynamic knee valgus were recruited. A Kistler force plate was used to record the kinetic data during three CMJ trials. Less peak power (estimated using allometric method) and greater landing force during countermovement jump were significantly correlated with valgus angle in female children (P= 0.033, R= -0.419, and P= 0.0.43, R= 0.413, respectively). Estimated peak power results using Sayers and Harman methods were significantly different from actual peak power outcomes (P=0.042, P=0.027 respectively). Greater landing force and decreased peak power during CMJ showed to be correlated with increased valgus angle in female children. Additionally, the allometric method seemed to be more accurate for estimating peak power compared to other methods.
