Effects of 12-weeks SMR Warm-up on The Lower Extremity Motor Function, Functional Movement Screen of Adolescent Poomsae Players

This study aims to confirm the effect of the SMR program, conducted as a warm-up before the Taekwondo training program, on adolescent Poomsae players" lower extremity motor function and FMS score. The subjects were randomly classified into the SMR group(SMRG, 19 people) and the general stretching group(GEG, 19 people). SMRG was performed by applying SMR warm-up exercise for 12 weeks. The collected data were analyzed using repeated two-way ANOVA, paired t-test, and independent t-test. The significance level of all statistical analyses was set at p<.05. The 12-week SMR program improved lower extremity flexibility, lower extremity muscle strength, Y-Balance, Deep Squat, In-line lunge, Active straight leg raise, and total scores in adolescent Poomsae players. However, it is difficult to say that there was a better improvement effect than GEG because there was no significant interaction in the internal and external rotation of the hip joint, muscle strength of the hamstring, in-line lunge, Active Straight height, and total.
