Abstract: A Preliminary analysis of forces acting on the head from the taekwondo turning kick Objective: To assess the effect of the TKD turning kick (RK) and its peak foot velocity (FVEL) on resultant head linear acceleration (RLA), head injury criterion (HIC15) and peak head velocity (HVEL).Methods: Each subject (n=12) performed five repetitions of the RK at the average standing head height for competitors in their respective Olympic weight division.A Hybrid II Crash Test Dummy (H2D) head was fitted with a protective TKD helmet and instrumented with a tri-axial accelerometer (PCB Piezotronics-356A66) and fixed to a height adjustable frame.Acceleration data were captured using Qualisys Track Manager (Gothenburg, Sweden) and processed in accordance with SAE J211-1.Results: The RK produced an RLA of 130.11±51.67g(range: 60.50-217.33g)and HIC15 of 672.74 + 540.89 (range: 128.40 -1608.70).The mean HVEL from the RK was 4.73±1.67m.s -1 (range: 3.36-9.52m.s -1 ).Height, weight, and foot velocity predicted 85.6% (SEE = 241.10) of the variance in HIC15 (p = 0.001, f 2 = 5.90) and of these predictors FVEL was statistically significant (p = .019).Conclusions: The RK is of concern because it is the most common technique and most common cause of concussion in TKD and has a high RLA and HIC15.Prevention of concussion in TKD should focus on employing qualified medical personnel, injury monitoring, and safer equipment.
