심부목굽힘근 운동이 VDT 증후군이 유발된 대학생의 등세모근 근피로도에 미치는 영향
이규리 ; 방현수 김천대학교 2010 김천대학교 논문집 Vol.31 No.-
The purpose of this study were to compare and analyze two types of deep cervical flexion exercise, craniocervical flexion and cervical flexion, and to ascertain their muscle fatigue on Trapezius. The participants of the study were 24 college students who were appropriately cho-sen and randomly divided into two groups, the experimental group underwent a cranio-cervical flexion exercise program and the control group a cervical flexion exercise pro-gram. The two-week experiment program consisted of the exercises performed three times a week and the education directed once a week per each group. Upper Trapezius muscle and lower Trapezius muscle fatigue were measured prior to and two weeks after the commencement of the experiment and again after two weeks. At the completion of six wecks, both experimental programs showed the decrease of muscle fatigue (p<.05). But the control group, which the cervical flexion exercise was done on showed no significant changes of the upper-leſt Trapezius muscle fatigue (p>.05). And the craniocervical flexion exercise program which was done on the experimental group was more effective in reducing upper Trapezius muscle fatigue (p<.05). The results of this study showed deep cervical flexion excercise was effective in the treatment of Trapezius muscle fatigue, however craniocervical flexion exercise was more effective than cervical flexion exercise in reducing upper Trapezius muscle fatigue.

The purpose of this study was to investigate the effects of angular velocity on muscle strength and activity of knee flexor and extensor. Subjects was classified into three groups, which were 60°/sec angular velocity group(n=10), 180°/sec angular velocity group(n=10) and 240°/sec angular velocity group(n=10). Each group was applied to perform the isokinetic exercises on flexion muscle group for each 7 times in 3 set(2 days per a week for 4 weeks). Muscle strength was measured using peak torque of quadriceps femoris and muscle activity was measured using RMS(roots mean square) of rectus femoris, biceps femoris, and semitendinosus. The results were as follows: 1. The peak torque was significantly increased after 4 weeks application of 60°/sec angular velocity isokinetic exercise(p<.05), however, it was not significantly after 180°/sec angular velocity isokinetic exercise application, and 240°/sec angular velocity isokinetic exercise application(p>.05). 2. The muscle activity was significantly increased after 60°/sec angular velocity isokinetic exercise application on biceps femoris and semitendinosus(p<.05), however, it was not significantly after 180°/sec angular velocity isokinetic exercise application, and 240°/sec angular velocity isokinetic exercise application(p>.05). This study showed that 60°/sec angular velocity isokinetic exercise application were effective treatment strategy on increase of muscle strength. Therefore, it could be considered as a treatment method in the athlete and patients with musculoskeletal disease.

본 연구는 비우세 팔굽관절 굽힘근육에 원심성운동을 실시하여, 지연성근육통을 유발시킨 후, 자연치유과 경 피신경전기자극치료, 그리고 냉치료의 효과를 조사하는데 그 목적이 있다. 자연치유군과 경피신경전기자극치료군, 그 리고 냉치료군의 평가를 위해 팔꿉관절의 운동시에 시상통증척도(VAS), 최대 염력, 실효치 값을 측정하여 평가하였 다. 대상자는 신체적 결함이 없는 30명의 성인을 대상으로 하였고, 대상자들은 지연성근육통 유발 후, 3개의 군인 자 연치유군, 경피신경전기자극치료군, 냉치료군으로 나누었고, 60°/초의 등속성 각속도에서 최대 근력으로 운동시에 최 대 연력과 실효치 값, 그리고 시상통증척도를 측정하여 평가하였다. 1. 시상통증척도는 경피신경전기자극치료군의 치료3일차에서 다른 군과 다른 기간에 비해 가장 낮은 수치를 나타내었 고, 통계적으로 유의하였다(p<.05). 2. 최대 염력은 경피신경전기자극치료군의 치료3일차에서 다른 군과 다른 기간에 비해 가장 높은 수치를 나타내었고, 통계적으로 유의하였다(p<.05).3. 실효치 값은 경피신경전기자극치료군의 치료3일 차에서 다른 군과 다른 기간에 비해 가장 높은 수치를 나타내었고, 통계적으로 유의하였다(p<.05). 이상의 연구 결과 로 보아 경피신경전기자극치료는 지연성근육통에 대하여 자연치유나 냉치료에 비해 더욱 효과적인 치료 방법임을 알 수 있다. 그러므로, 지연성근육통을 가진 환자의 치료 시에 경피신경전기자극치료의 적용은 권장되어야 한다. The purpose of this study was to investigate the spontaneous therapy, TENS(transcutaneous electrical nerve stimulation) and ice therapy after induction of DOMS(delayed onset muscle soreness) through application of eccentrically exercise in ralation to biceps brachii muscle of opposite-dominance. And to explain this, we analyzed VAS(visual analogue scales), peak torque, RMS(roots mean square) when exercising elbow joint. The subjects were 30 adults without any physical defect. Subjects were divided into three groups that spontaneous therapy, TENS therapy and ice therapy after DOMS induction, choosen movement could get the maximal peak torque in angular velocity of 60°/sec, and mearsured peak torque, RMS and VAS. 1. The VAS was significantly decreased after 3 days application of TENS than other groups(p<.05). 2. The peak torque was significantly increased after 3 days application of TENS than other groups(p<.05). 3. The RMS was significantly increased after 3 days application of TENS than other groups(p<.05). This study showed that TENS therapy application were effective treatment strategy on DOMS than spontaneous therapy and ice therapy. Therefore, it could be considered as a treatment method in the patients with DOMS.
