강설중 ( Kang Seol-jung ),김영선 ( Kim Yeong-sun ),윤재량 ( Yoon Jae-ryang ) 한국체육대학교 체육과학연구소 2017 스포츠사이언스 Vol.35 No.1

본 연구는 근대5종 선수를 대상으로 하지관절인 무릎관절의 등속성 근관절 기능을 측정하여 슬관절의 주동근(신근력)과 길항근(굴근력)이 균형을 이루고 있는지를 진단, 평가하는데 있다. 본 연구에 참여한 연구대상은 서울 소재 K대학교 재학생 근대5종 선수 중 8명을 선정하였으며 선수경력 평균 9년 이상인 자를 대상으로 하였다. 근대5종 선수의 슬관절 등속성 기능평가를 하기 위해 피험자의 체성분을 측정 후 등속성 근관절(60°/sec, 240°/sec)를 수행하였다. 이에 대한 연구결과는 다음과 같다. 첫째, 좌측과 우측 슬관절 근력비(좌우비)의 균형여부 평가 결과, 신근력의 대퇴사두근에서는 좌측과 우측간에 비교적 정상적인 균형을 이루고 있으나 굴근력의 햄스트링근에서는 좌측에서 상대적으로 상당히 약한 것으로 나타났다. 따라서, 좌,우 양측 균형을 위해서는 슬관절의 햄스트링 근력강화 트레이닝이 필수적인 것으로 평가되었다. 둘째, 동측 슬관절의 근력비(굴신비)의 균형여부 평가 결과, 신근력의 주동근인 대퇴사두근은 대체로 정상에 가까운 수준을 보이고 있으나 굴곡근의 주동근인 좌, 우측 햄스트링근은 상당히 약한 것으로 나타났다. 따라서, 좌측과 우측 모두에서 슬관절의 햄스트링 근력강화 트레이닝이 필수적인 것으로 평가되었다. 선수 개인별 분석결과를 종합해보면, 본 연구에 참여한 근대5종 선수들은 지속적인 웨이트 운동과 같은 근력강화 트레이닝을 실시하되, 일정 주기별로 슬관절의 근기능 검사를 통해서 동측 근력비와 양측 굴신비의 불균형 여부를 평가하고, 이에 대한 적절한 근력 보강트레이닝, 특히 햄스트링근의 보강 트레이닝이 철저히 요구됨을 확인할 수 있었다. The purpose of this study is an analysis and diagnose isokinetic function of knee joints in modern pentathlon college athletes. The subjects of this study were 8 college athletes(9years over) of K university in Seoul. In order to evaluate the isokinetic function of the knee joints of the modern pentathlon athlete, the isokinetic test (60 ° / sec, 240 ° / sec) was performed after measuring the body composition of the subject. The results of this study are as follows. First, the balance between the left and right knee strength ratios (left to right ratio) was evaluated to be relatively normal balance between the right and left quadriceps muscles, but relatively weak in the hamstring muscles of the left flexor muscles. Therefore, it is estimated that hamstring strengthening training of the knee is essential for both left and right balance. Second, as a result of evaluating the balance of muscular strength (flexor/extensor ratio) of the isolateral knee, the quadriceps muscle of the extension muscle is near the normal level, but the left and right hamstring muscles of the flexor muscles are significantly weak. Therefore, it was evaluated that hamstring strengthening training of the knee was necessary in both the left and right side. In conclusion, the athletes perform strength training such as continuous weight training, and evaluate the imbalance of isolateral strength ratio and bilateral flexor- extensor ratio through the strength examination of the knee at regular intervals. In particular, it was confirmed that adequate hamstring strength training was required.
