[목적] 이 연구는 다양한 TRX의 다양한 플랭크 동작 시 동작 난이도와 불안정성에 따른 코어 안정화 근육의 활성도를 비교하고 TRX의 운동효과를 살펴보고자 실시되었다. [방법] 연구대상은 생체 3급 자격증을 소지한 20대의 건강한 남성 10명을 대상으로 하였다. 안정된 면인 평지와 불안정한 면인 TRX 및 스위스볼에서 엎드린 자세, 누운 자세, 사이드 플랭크의 다양한 동작을 실시하게 한 후 코어의 안정화 근육인 상.하부복직근, 외복사근, 내복사근/복횡근, 척주기립근 및 다열근의 활성도를 측정하였다. [결과] 엎드린 자세 플랭크 동작 시 코어 안정화 근육 중 상부와 하부복직근은 불안정성에 따른 유의한 차이를 나타내었으며, 외복사근, 내복사근/복횡근, 척추기립근, 다열근은 동작 난이도에 따른 유의한 차이를 나타내었다. 누운 자세 플랭크 동작 시에는 상.하부복직근과 척추기립근이 동작 난이도에 따른 유의한 차이를 나타내었다. 사이드 플랭크 동작 시에는 상.하부복직근, 외복사근, 내복사근/복횡근, 척추기립근, 다열근이 모두 동작 난이도에 따른 유의한 차이를 나타내었으며, 하부복직근과 척추기립근은 불안정성에 따른 유의한 근활성도의 차이를 나타내었다. 그러나 TRX와 스위스볼의 근활성도 차이는 나타나지 않았다. [결론] TRX를 이용한 다양한 플랭크 동작 시 코어 안정화 근육의 활성도는 전통적인 플랭크 동작 시에는 불안정성에 따라 근활성도가 증가하고 누운 자세와 사이드 플랭크 동작 시에는 동작의 난이도가 증가할수록 높은 근활성도를 나타내었다. 따라서 플랭크 자세에 따라 차이가 있지만 코어 안정화 근육을 활성화시키기 위해서는 동작의 난이도를 증가시키는 동작이 효과적일 것으로 생각되며, TRX와 스위스볼은 근활성도의 차이가 없었으므로 TRX도 스위스볼과 유사하게 코어 안정화에 효과를 가져올 수 있는 운동인 것으로 사료된다.
Abstract
[PURPOSE] This study aimed to compare core stabilizer muscle activity according to movement difficulty and stability during various TRX plank. [METHODS] Ten healthy male students who have certificate of 3 grade body builder were examined core stabilizer muscle activity as upper and lower rectus abdominis(URA and LRA), external oblique(EO), internal oblique/transverse abdominis(IO/TrA), erector spinase(ES), and mutifidis(MF) during various lay-down, supine, and side-plank. [RESULTS] In the results of lay-down plank, URA and LRA was showed a statically significant difference according to stability and IO/TrA showed a statically significant difference according to movement difficulty. However, TRA and swiss ball showed no statistically significant difference. The results of supine-plank, URA, LRA, and ES was showed a statically significant difference according to movement difficulty. The results of side-plank, URA, LRA, EO, IO/TrA, ES and MF showed a statically significant difference according to movement difficulty and ES also showed a statically significant difference according to stability. [CONCLUSIONS] We concluded that traditional lay-down plank was showed a significant difference according to stability and supin and side-plank was showed a statically significant difference according to movement difficulty. Therefore, we suggested that various TRX plank can help improve core stabilizer muscle activity as well as swiss ball and various plank using TRX may have a positive effect on core muscle activity for trunk stability.
