Effects of Explosive Strength Training on Lower Limbs in Taekwondo Athletes

Abstract

Introduction: Taekwondo is a sport of highly competitive intensity, and the gain in physical fitness of its practitioners is a work that involves analysis of combat techniques, sports biomechanics, and theories of physical training. However, studies of current methods, such as explosive strength training, are still superficial. Objective: Study the effect of different explosive strength training protocols on the lower limbs of taekwondo athletes. Methods: 24 taekwondo athletes were randomly selected as volunteers and divided into experimental and control groups. These were subdivided to perform traditional and different strength training combinations. The experiment lasted eight weeks, with the first four weeks dedicated to strength training adaptation. Data on body shape, maximal strength, explosive strength, and fitness were collected for statistical comparison. Results: Through repeated measures analysis of variance to test lower limb explosive strength on exercise level, it can be seen that there is a significant difference between the test data before and after the approach (P<0.05), this difference was not observed in the control group (P>0.05). The mean value of all indexes in the experimental group was higher than in the control group. Conclusion: Explosive strength training and its different combinations on lower limbs can significantly improve the physical fitness of taekwondo athletes. The different combinations of strength training presented can be used as an effective resource in the lower limbs athletes’ explosive strength gain.
