The effect of jump-landing exercises and strength exercises on performance improvement, dynamic balance and selected kinetic and kinematic factors of taekwondo athletes (Poomsae) with dynamic knee valgus defect
The effect of jump-landing exercises and strength exercises on the performance of taekwondo athletes (Pomse) with dynamic knee valgus defect.
The effect of jump-landing exercises and strength exercises on the dynamic balance of taekwondo athletes (Pomse) with dynamic knee valgus defect.
The effect of jump-landing exercises and strength exercises on kinetic and kinematic variables
Design
60 people with the age range of 14 to 22 years were selected from among the available population with the opinion of a specialist doctor and participated in the research voluntarily. The number of samples was estimated by G* power statistical software, considering the average effect size of 0.5, power of 0.80, and alpha of 0.05. Among the statistical population, 60 subjects prone to anterior cruciate ligament injury were selected purposefully, taking into account 10% drop. Then they were randomly divided into 3 groups (jump-landing training group of 20 people, jumping-landing and strength training group of 20 people and control group of 20 people).
