Kinematic Determinants of Front Kick Dynamics Across Different Loading Conditions

Popis výsledku v původním jazyce

Introduction The efficiency of front kick is related to the kicking technique. Thus, the aim of this study was to find the kinematic determinants of front kick dynamics across different performance and loading levels (no load to 45-kg load). Materials and Methods Twenty-four elite and sub-elite professional military personnel (26.8 +- 10.1 years, 84.2 +- 5.4 kg, 181.1 +- 6.4 cm) performed six front kicks into a force plate across five different loading conditions. Three-dimensional kinematics of the kicks was quantified and included velocity of the hip (Vhip), velocity of the knee (Vknee), velocity of the shoulder (Vshoulder), velocity of the foot (Vfoot), angular velocity of the knee (AVknee), and angular velocity of the hip (AVhip). Results The main kinematic differences between the two groups were that the sub-elite group had an increased kick time for all loading conditions (P &lt; .001) and a lower Vfoot (P = .05) and a decreased Vhip and Vshoulder (P &lt; .05) in the highest load condition. Vhip and AVhip were the best predictors (up to R2 = 0.58; P = .020) of peak force and impact force during no-load or loaded kicking at the elite level. Typical predictors of impulse in the elite group were AVhip, Vhip, and Vshoulder and those in the sub-elite group were AVknee and Vfoot. Conclusions The kinematic variables provide good predictions of kicking dynamics; however, the best predictor varies with the loading conditions and performance levels. Hip motion is the main differentiating factor.
