  • Active and therapeutic sport recovery is becoming a popular and important component in approving performance for pro and recreational athletes alike. It is also helping in the realm of injury prevention. In the search of finding modalities that are widely effective, natural, and safe, acupuncture is a viable and cost-effective treatment for helping athletes achieve this goal. More direct related research is needed, but testimonials from pro athletes and the body of research that currently exists provides powerful evidence on acupunctures ability to help with enhancing recovery. Specializing in acupuncture and exercise science, Chris integrates acupuncture into musculoskeletal rehabilitation therapy or fitness training for pain modulation, speedy recovery, and enhanced performance. Clients can choose to focus on one-on-one corrective exercise therapy, manual and massage therapy, or acupuncture. However, for best results, Chris recommends all three. Other modalities that he uses in therapy are acu-taping, herbal therapy, nutrition supplementation, cupping, guasha, and stretching techniques. The corrective exercise component is one-on-one body balancing management, focusing on strength and conditioning, post physical rehab - exercise therapy, integrative sport specific exercise, weight loss, core strengthening, dynamic lumbar stabilization, active recovery techniques, and myo-fascial release techniques. The acupuncture component focuses on sport injuries, myofascial pain, peripheral neuropathy, arthritis, facial rejuvenation, stress, smoking cessation, addiction detoxification program, weight management, sport recovery and performance.

  • Purpose: The purpose of this study was to figure out how PAP (Post-Activation Potentiation) phenomenon affects short-term performance efficiently. Methods: This study was conducted with 18 Taekwondo athletes and 16 healthy adults. By using isokinetic dynamometer, two different intervention, TDP (Top-down program) and BUP (Bottom-up program), were performed to measure isokinetic parameter; (peak torque: PT, total work: TW, average power: AP, and average torque: AT) of knee extensor for intragroup, intergroup comparison and two-way ANOVA. Results: The Taekwondo athletes group showed statistically significant differences in all isokinetic parameters PT, TW, AP, and AT after TDP (p<0.05). However, in the healthy adult group, the difference in isokinetic parameters according to the exercise sequence was not statistically significant. (p>0.05). PT and TW at TDP were statistically significant (p<0.05) when the rate of change in TDP and BUP was compared and analyzed considering the difference in physical ability between the Taekwondo athlete group and the healthy adult group. However, AP and AT were not statistically significant. Finally, when examining the interaction between the two groups and two exercise sequence according to isokinetic parameters, only TW (p<0.05) showed a statistically significant interaction, while PT (P=0.099), AP (P=0.103), and AT (P=0.096) did not. This study suggests that short-term performance can be improved through the PAP phenomenon when TDP is applied to the Taekwondo group. Conclusion: According to our result, for Taekwondo athletes, if the goal is to improve short-term performance just before the main game, we suggest a training program through TDP.

  • PURPOSE: The purpose of this study was to investigate the current state of rapid weight loss and physical and mental complaints among elite combat athletes who were selected and trained as national representatives. METHODS: A total of 127 combat athletes who had trained at the national training center in 2019 were enrolled. The questionnaire used as the survey tool was interpreted as words that Korean athletes could easily understand based on the Portuguese version of the 'Rapid Weight Loss Questionnaire' (RWLQ). χ2 tests was performed to determine the differences in physical and mental changes according to sports and weight loss method. RESULTS: Combat athletes in Korea regularly undergo rapidly weight loss within a short period of time prior to competition. There were statistically similar results in terms of weight loss method, physical and mental changes and information about weight loss according to the sport. Weight loss methods often limit food and water intake and dehydrate. The physical complaints associated with them are symptoms such as "no energy", "dizziness", and "muscle spasms". The mental complaints include "irritability", "concentration loss" and "anxiety". These symptoms can be caused by side effects such as food intake limitation, water restriction and dehydration. Information sources for weight loss were in the order of "senior or colleagues", "supervisor or coach", and "Internet". No information was obtained from a doctor or dietitian. CONCLUSION: These results provide a baseline for predicting proper weight loss in athletes and provide useful information for developing performance enhancement as well as weight loss.

  • The purpose of this study was to analyze the kinematic characteristics of javelin to compare the characteristics between world elite athletes and local male athletes. The subjects selected 9 athletes out of total 13 athletes recorded more than 65 m in the preliminary and main competition participated in the 93rd National Sports Festival held in 2012. Three-Dimensional motion analysis using a system of 4 video cameras(Sony HXR-MC2000) at a sampling frequency of 60 fields/s was performed for this study. The Kwon3D 3.1 was used to obtain the three dimensional coordinates about the top, grip, end of javelin. And the kinematic factors of javelin calculated using Matlab2009a program. The resultant speed of javelin that affects directly to the record of performance showed 26.08 m/s indicated lower speed of about 2-3 m/s than world elite athletes. The release point appeared to have been made at the high of $1.79{\pm}0.07$ m of 99.8% of the height of the athletes. In terms of release angle, it was indicated average $33.0{\pm}3.81^{\circ}$ lower release angle compared to the world elite athletes. The attitude angle(up & down tilt angle, X axis) related to javelin indicated average $38.5{\pm}4.96^{\circ}$, its related attack angle average $5.5{\pm}5.11^{\circ}$, and yaw angle(sideslip, side attack angle) average $15.7{\pm}8.48^{\circ}$.

  • Objective: In this study, we compared the key indices of isokinetic tests for knee joint extension and flexion according to the presence or absence of pain in elite athletes with past knee and thigh injuries. Design: Crossed-sectional study Methods: This study was conducted on 33 elite athletes. The elite athletes who participated in this study were divided into a group with pain and a group without pain due to past knee and thigh injuries. The subjects in each group performed an isokinetic muscle strength test for knee joint extension and flexion. After the isokinetic muscle strength test, the main indices of the isokinetic test were compared between the pain group and the non-pain group. Results: In the comparison of the pain group and the non-pain group for 60°/s knee flexion and extension in elite athletes, there was a significant difference only in the torque max average/kg for knee extension. However, there was no statistically significant difference in all other variables. The comparison of the pain group and the non-pain group for 240°/s also showed a significant difference in the torque max average/kg for knee extension, and there was no statistically significant difference in all other variables. Conclusions: In subjects who have experienced previous knee or thigh injuries and have mild pain during strong isokinetic strength tests, torque average/kg is affected, but other strength variables are not affected. Therefore, it would be good to consider this aspect and use it as a basis for testing and training elite athletes.

  • 이번 리뷰는 엘리트 선수들의 경기력 향상을 위해 사용되고 있는 운동영양 보조물 이용 현황을 탐색하고 도핑교육, 종목특성, 경기력, 성별, 연령 등에 따른 운동 영양보조물 이용 차이의 이유를 살펴보는데 목적이 있다. 선행 리뷰연구들에서는 선수들이 이용하고 있는 운동영양 보조물항목의 생화학적 특성 및 기능, 이용 빈도를 중심으로 논의되어 왔으며 운동영양 보조물을 "왜 선수들이 이용하고 있는지" 관련한 논의는 부족하였다. 선수들의 반 도핑교육은 운동영양 보조물 이용 시 전문지식 함량증가로 인해 이용 빈도를 증가시키며, 미량의 영양소가 경기결과에 직접적으로 영향을 미치지는 못하지만 장기간 이용으로 인해 인체에 긍정적인 효과를 이끌어 경기력에 잠재적 영향을 미칠 것으로 예측된다. 더욱이 성별과 연령에 따른 차이는 종목특성에 기인되며, 섭취목적에 따른 이용항목을 고려해볼 때 경기력보다는 건강 및 컨디션 유지로 인한 섭취가 원인으로 생각된다. 대부분의 선수들은 단일 항목을 단기간 섭취하기 보다는 2가지 이상 항목을 장기간 섭취하고 있으나 효과와 관련한 과학적인 근거가 부족하여 이를 위한 실험적 연구접근이 요구된다.

  • 근대5종 경기는 기구 없이 하는 운동과 기구를 사용하는 운동 그리고 동물과 함께하는 운동은 물론 사람과 사람이 경쟁하는 운동뿐만 아니라 정적운동과 동적운동을 포함하는 운동 종목이다. 근대5종 경기 선수들의 윤리적인 문제는 열악한 환경과 경제적 이유와도 관계가 있으며 운동선수의 윤리인식과 태도, 그리고 정신은 스포츠 선수의 심적 환경에 많은 영향을 주고 있다. 본 연구에서는 현대 스포츠에서 중요한 문제로 다르고 있는 윤리적인 문제들의 개선 방향을 검토하고자 질적 연구방법을 적용하여 근대5종 경기의 스포츠 정신과 윤리성을 탐색하고자 하였다. 스포츠에서 보상주의는 경기력 향상이나 기록 갱신의 원인이 되기도 하지만 때로는 왜곡된 선수상의 형성 원인이 되기도 한다. 에어도핑은 선수의 건강이나 공정성의 논란과 함께 스포츠선수의 정신적 육체적 손상과 폐해를 야기할 수 있는 윤리적 문제를 안고 있다. 금지약물을 복용하는 선수나 이를 방치하거나 종용하는 지도자나 감독자의 책임과 윤리문제는 매우 중요한 사안으로 다루어지고 취급되어야한다. 스포츠 현장에서 선수나 감독 지도자의 경기실적에 종속된 보수체계가 선수나 지도자의 생계와 연관이 있기 때문에 공정하고 정의로운 경기진행을 위해 성과에만 매달리는 선수육성에서 탈피하여 이념과 논리에서 합리적으로 인식되는 윤리성회복을 강조함으로써 비윤리성문제가 극복되어야 할 것이다.

  • In view of the importance of muscle-specific creatine kinase (CKMM) gene as a genetic factor for athletic performance, we investigate the relationship between elite athletic performance and two restriction fragment length polymorphisms (Ncol and Taql RFLPs) in the CKMM gene. Genomic DNA was extracted from white blood cells of 98 unrelated male Korean elite athletes and 04 sedentary controls, respectively. Two genetic polymorphisms in the CKMM gene were detected by the polymerase chain reaction and the digestion with restriction endonucleases, Ncol and Taql, respectively. There were no significant associations between two genetic polymorphisms in the CKMM gene and elite athletic performance or clinical parameters in our subjects. Therefore, these findings suggest that two genetic polymorphisms in the CKMM gene may not be useful as genetic markers to predict the athletic performance in male Koreans.
