Comparison of Isokinetic Muscle Function and Anaerobic Exercise Capacity in the Knee According to Kukki Taekwondo Training Type

Abstract

Introduction: This study’s purpose was to measure and compare isokinetic muscle function and anaerobic exercise capacity of knee joints according to the three Kukki Taekwondo competition types. Methods: A total of 21 elite Korean male poomsae (forms), gyorugi (sparring), and demonstration athletes majoring in Taekwondo were selected as the subjects of the study. Subjects’ physical fitness levels were measured using standardized strength, endurance, agility, balance, and flexibility tests. In particular, the isokinetic muscle function measurement system was used to measure the muscle function of subjects’ knee joints, and the Wingate test was used to measure their anaerobic exercise ability. Results: Gyorugi athletes showed better results than their poomsae and demonstration counterparts in nearly all metrics, including body composition, physical fitness factors, isokinetic muscle function (60°/sec), muscle power (180°/sec), and anaerobic exercise capacity. Gyorugi athletes were also taller and showed higher muscle mass, strength, muscular endurance, and agility. However, poomsae athletes showed a higher level of flexibility. The results found isokinetic muscle function and anaerobic exercise capacity of the knee joint to be most important for gyorugi athletes and then for demonstration and poomsae athletes, in that order. Conclusions: This study provides useful information needed to identify the physical fitness factors of the different Kukki Taekwondo athletes, and, in turn, it is may serve as important fundamental data for developing future systematic Taekwondo training programs.

The investigation of isokinetic knee strength and muscle balance of taekwondo and wrestling athletes

“…In addition, the statistical difference between H/Q ratios (p<0.05) shows that taekwondo athletes have lower H/Q strength ratios. In previous isokinetic studies, it was determined that the knee isokinetic strength of taekwondo (Choi et al, 2021;El-Ashker et al, 2022;Hammami et al, 2013;Harbili et al, 2022;Kang et al, 2021) and wrestling (Çimen Polat et al, 2018;Drid et al, 2009;Hoseini et al, 2022;Kraemer et al, 2001;Tatlici, 2021;Tatlici et al, 2021) athletes supported our research results. This result may be due to the fact that taekwondo explosively trains roundhouse and rotating kicks that require lower extremity FLX and EXT strength.…”

“…Previous studies have shown that knee FLX and EXT strength results measured with isokinetic dynamometers are highly reliable (Brown et al, 2005;Feiring et al, 1990;Hartmann et al, 2009;Jenkins et al, 2015;Maffiuletti et al, 2007;Sole et al, 2007). Therefore, in sports like taekwondo and wrestling where the legs are actively used, isokinetic dynamometers are widely preferred for measuring knee flexion and extension strength or quadriceps (Q) and hamstring (H) muscle strength (Coban et al, 2021;Hammami et al, 2013;Harbili et al, 2022;Kang et al, 2021;Tatlici et al, 2021).…”

Taekwondo as an Academic Field of Study for Non-Koreans: An Unconventional and Extreme Form of Martial Arts Tourism

“…Table 1 shows participants' demographic data. As in other Taekwondo research [36], participants' Taekwondo rank, training time, and Taekwondo style were also identified as potential variables that could influence their motivation for studying in the ROK (e.g., Taekwondo style). In addition to the expected demographic data, such as age and nationality, participants' dan and years of Taekwondo practice were included to indicate their expertise in evaluating their education (Table 1).…”

Cyclic Anaerobic Exercise Performance and Neuromuscular Activity Based on Artificial Intelligence Genetic Algorithm

“…He selected 21 athletes as research subjects. The results demonstrated that the tested athletes performed better than their peers on almost all metrics, including body composition, physical fitness factors, isokinetic muscle function, muscle strength, and anaerobic capacity [5]. Park proposed that the need for lactate cycling after aerobic exercise eliminates lactate produced during exercise, a process that requires energy expenditure.…”
