Effects of 8-week Kettlebell Training on Lower Extremity Anaerobic Power and Muscle Thickness in Taekwondo Poomsae Athletes

The purpose of this study is to suggest an appropriate training method by examining the effect on lower extremity anaerobic power and related muscle thickness through 8 weeks of kettlebell training in Taekwondo Poomsae athletes. Seven athletes who are currently registered as athletes were selected and kettlebell training was performed for 8 weeks, and the difference was confirmed by performing the Wilcoxon-test, a non-parametric test, through pre and postmeasurement measurements. For this study, the difference was measured using a wingate anaerobic power measuring instrument and an ultrasonic instrument. As a result of the study, significant improvements were found in average power per body weight and peak power of anaerobic power. The five representative muscles of the lower extremities, rectus femoris, vastus lateralis, vastus intermedius, vastus medialis, and biceps femoris long muscle, all showed significant improvement.
