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.

This case study applied the Dahn Taekwondo Spondylitis Improvement Program (DTSIP) to a 30-year-old male with ankylosing spondylitis five times a week for 28 weeks. Materials and Methods: A 32-year-old male with ankylosing spondylitis underwent the Dahn Taekwondo Spondylitis Improvement Program (DTSIP), an amalgamated program of standard Western medicine practices and complementary and alternative medicine (CAM) exercises based in the oriental medicine practices of yoga and taekwondo. The subject performed the DTSIP 5 times a week for 90 minutes for 28 weeks. Results: First, blood C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and platelet levels decreased by approximately 29-71%. Second, blood leukocyte counts decreased by about 11%. Third, as a result of Bath Ankylosing Spondylitis Metrology Index (BASMI) measurement, tragus to wall (TWD), lumbar side flexion (LSF), LF (lumbar flexion), and intermalleolar distance (IMD) were improved substantially. The students' cervical vertebrae and thoracic and lumbar vertebrae ranges of motion were additionally improved. The range of motion of the shoulder and hip joint improved. Conclusions: Therefore, the DTSIP seems to have a positive effect on the inflammation, immune functions, and spine and joint range of motion in the subject of this case study. Future studies are required with a wider sample population to validate these results.
