“…In this study, we found that sparring athletes have greater rearfoot varum alignment than demonstration athletes. These results are similar to those of previous studies that found no difference in kinematic variables between the dominant and nondominant legs of sparring athletes [ 31 , 32 ]. The kicks of sparring athletes combine throw-like and push-like motions, with a high frequency of performing such techniques from an undefined height and distance [ 32 ].…”

Background and Objectives: Studies analyzing lower extremity alignment (LEA) LEA among taekwondo subdisciplines athletes are lacking. This study compared LEA in the dominant and nondominant legs intaekwondo athletes. Materials and Methods: Twelve measurements of LEA were analyzed for 157 athletes (63 sparring, 50 demonstration, and 44 poomsae athletes) registered with the Korea Taekwondo Association. LEA was measured in the standing, supine, and prone positions using alignment application, a goniometer, a bubble inclinometer, a height gage, and a palpation meter. Results: The analysis revealed that the dominant leg of poomsae athletes showed greater genu valgum alignment than that of sparring athletes (p < 0.01), whereas the dominant leg of sparring athletes showed greater rearfoot varum alignment than that of demonstration athletes (p < 0.01). Furthermore, the nondominant leg of poomsae athletes showed greater genu valgum alignment than that of sparring and demonstration athletes (p < 0.01), whereas the nondominant leg of sparring athletes showed greater rearfoot varum alignment than that of demonstration athletes (p < 0.01). In addition, demonstration athletes had better forefoot varus alignment than poomsae athletes (p < 0.01). Conclusions: This study revealed that LEA characteristics vary among taekwondo athletes according to their subdiscipline. The results of this study would help in designing training programs tailored to each subdiscipline that would best address their LEA characteristics and help to prevent injuries.

“…Because there are certain differences in age composition, training time, sports years, and sports performances of our study subjects, there are also differences in the incidence of ankle joint injuries. 5 This investigation found that the incidence of ankle joint injuries among young Taekwondo athletes is higher, and the severity will affect their sports training.…”

Introduction: With the extensive and in-depth development of Taekwondo in China, more and more people participate in Taekwondo training. Due to the lack of experience of some coaches and the misunderstanding of scientific sports training by young athletes, injuries occur from time to time. This has a bad effect on Taekwond itself, and it can also damage the health of athletes. Objective: This article discusses joint injuries in Taekwondo and analyzes the characteristics of Taekwondo sports injuries and preventive methods. Methods: This article uses a questionnaire applied to young athletes to gain an understanding of the sports injuries situation. Results: The most common injury sites were feet and joints. The nature of the injuries is mostly soft tissue injury, ligament laceration, and muscle strain. The most serious injuries are kidney and perineal damage. Conclusion: Improving the level of training, strengthening medical supervision, and paying attention to the timely treatment of acute injuries are important ways to reduce the occurrence of trauma. Level of evidence II; Therapeutic studies - investigation of treatment results.

“…Eighteen studies employed isokinetic dynamometer [ 22 , 29 , 33 , 34 , 42 – 55 ], five studies used photogrammetry [ 2 , 3 , 35 , 56 , 57 ], two studies used goniometers and photogrammetry [ 58 , 59 ], two studies used an electrogoniometer [ 32 , 60 ], three studies used a potentiometer [ 61 – 63 ], four studies used a goniometer [ 43 , 64 – 66 ], two studies used a joint position sense device [ 67 – 69 ], three studies used an inclinometer [ 70 – 72 ], one study used an Air Splint [ 73 ], one study used an optotrak [ 74 ], and two study used a self-design device [ 31 , 69 ]. In addition, the following studies employed two types of measurement error: 36 studies investigated the absolute angular error [ 2 , 3 , 22 , 29 , 31 – 35 , 42 – 51 , 53 – 59 , 63 , 65 , 67 – 74 ] (absolute difference between the target position and the estimated one), while 12 studies investigated the relative angular error [ 2 , 3 , 31 , 42 , 46 , 50 , 56 , 57 , 61 , 62 , 64 , 72 ] (difference between the target position and the repositioning angle, taking the direction of the difference into account).

Introduction An injury can significantly harm both individual and team performance. One of the most important risk factors for sports-related injuries, especially non-collision injuries, is fatigue. It seems that poor proprioception may play an essential role to impose athletes to further injuries. This systematic review and meta-analysis aimed to examine the effectiveness of fatigue on the repositioning sense of the lower extremity joints. Method The electronic databases, including PubMed, Web of Science, Scopus, and Google Scholar were systematically searched from inception to 11January 2024. The obtained records were exported to the EndNote Software version 8. Then, two investigators examined the records independently to find eligible studies based on the inclusion/exclusion criteria. In the case of disagreements, a consequence method was utilized. The quality of the eligible studies was evaluated using the Downs and Black checklist. Comprehensive Meta-Analysis (CMA) software ver. 3 software was used for statistical analysis. Q-test and I2 were employed to examine the data homogeneity. In addition, considering the risk of bias, the Funnel Plot and trim-and-fill method were used. Results After reviewing the titles and abstracts of 3883 studies found in the selected databases, 43 articles were found to be eligible to include in meta-analyses. The results showed that fatigue led to a significant increase in the active absolute error of the knee (SDM = 0.524, 95% CI = 0.406–0.841), ankle in the horizontal plane (SDM = 0.541, 95% CI = 0.367–0.715), ankle in the sagittal plane (SDM = 0.443, 95% CI = 0.088–0.798), and hip (SDM = 0.988, 95% CI = 0.135–1.841). However, fatigue had no significant effects on the passive absolute error of the knee and ankle in horizontal plane and relative angular error of the knee. Conclusion Fatigue can diminish the active joint position sense of the lower extremities and thus may increase the risk of injury by reducing proprioception. Therefore, future research could be conducted to investigate the potential impact of integrated fatigue-mitigating exercises into athletes’ training programs, with the aim of reducing the incidence of sports-related injuries.
