The purpose of this study was to investigate effect of low-dye taping and foot intrinsic muscle strengthening exercise on the muscle activity of the tibialis anterior, calf muscles, and long calf muscles during one-foot standing in subjects with flat feet. The subjects were 16 adults in their 20s with flat feet, and they were divided into low-dye taping (LTG; n=8) and foot intrinsic muscle strengthening exercise (FSG; n=8) groups. Each group underwent the appropriate intervention twice a week for 6 weeks. The muscle activity of the tibialis anterior, long calf muscle, and medial calf muscle was measured. Repeated two-way ANOVA was performed to compare changes in muscle activity before and after the intervention. As a result of muscle activity measurement, LTG significantly decreased between before and after the experiment in all muscles (p<.05). In FSG, only the tibialis anterior significantly decreased between before and after the experiment (p<.05). Therefore, low-dye taping and foot intrinsic muscle strengthening exercises will be helpful for efficient the lower extremity muscle activity of flat foot.

연구의 목적 : 건강한 20대 성인 남녀에게 복부 강화 운동의 하나인 warm-up (head to toe)와 tongue-stretching 운동 시 복근의 근 활성도를 비교하는데 연구의 목적이 있다. 연구의 방법 : 본 연구는 12명의 건강한 20대 성인 남녀(남 5, 여 7)를 대상으로 하였으며, 평균 연령은 26세이다. 연구의 대상자는 복근에 sEMG 도자를 부착하여 두 운동 적용 시 복부 근활성도에 대한 남녀의 차이와 개별 운동 시 각 근육간의 근활성도 차이를 SPSS 13.0을 이용하여 분석하였으며, 두 운동 적용 시 global 근육과 local 근육간의 비율을 1이라 가정하고 기여도를 측정하였다. 연구의 결과 : 연구의 결과는 다음과 같다. 1) 두 운동을 적용 시 남녀의 차이는 없었다. 2) 두 운동 적용 시각 근육간 근활성도 차이는 보이지 않았으나, 배속빗근(internal oblique)는 차이를 보였다. 3) 두 운동 적용 시global 근육과 local 근육간의 비율은 배곧은근(rectus abdominis)과 배속빗근과의 비율은 3으로 배속빗근이 배 곧은근의 근활성도 보다 컸음을 보였으며, 배바깥빗근(exernal oblique)과 배속빗근과의 비율은 약 1.5로 배속빗근의 활성도가 컸다. 연구의 결론 : 복부 강화 운동의 하나인 warm-up과 tongue-stretching 운동을 적용 시 복근의 활성도를 비교한 결과에서 보여주듯이 local 근육 강화 운동 시 두 운동의 효과를 향후 분석하여 요통환자와 같이 복부 강화가 필요한 환자의 프로그램에 적용되어져 할 것이다.

A computer model of the musculoskelotal system that provides accurate prediction of muscle force and body movement trom the stimulation input is desired for the effective control system design in FES. This paper aims to investigate the fundamental properties of the gradual muscle force potentiation that was not included in the previous muscle models, for future development of a model that provides vetter prediction of FES-induced muscle force and body movement. Specifically, hou the muscle length was investigated. The experimental results showed that both the force increment ratio and the time-to-peak during electrical stimulation decreased with stimulatino frequency. When the muscle potentiation state was saturated by preceding stimulation. the force did not increase any more during additive stimulation. Muscle length significantly affected the force potentiation in such a way that the force increment ratio decreased with muscle length. A new model of the muscle potentiation based on these results is desired in the future.

The endogenous steroids from human urine were simultaneously analyzed by selected ion monitoring method of GC/MS which is currently used for the doping procedure, together with anabolic steroids. The recovery range of this method was 72.33 %∼94.54% and the RSD values of precision and accuracy test were 1.43%∼10.86%, 0.96%∼9.98%, respectively. Using this method steroids profile was investigated in the urine of male volunteers after oral administration of nine anabolic steroids banned by IOC (International Olympic Committee). Urinary endogenous steroids level was varied specifically according to the excretion tendency of the metabolites of anabolic steroids.

Background: This study was to investigate the effects of spinal strengthening exercise and lumbar stabilization exercise(core exercise program) on trunk muscle strength, flexibility and balance, lumbar function. The subjects of this study were the eighteen subjects who was registered in private guard company. The each exercise group of 9 persons were chosen by random controlled trial. Methods: We used instrument BTE, Libra, Ruler Measuring tape to measured trunk muscle strength, flexibility, balance and lumbar function. Results: The result of this study were summarized below; The flexor muscle strength was improve in lumbar stabilization exercise(core exercise) group(p<.05). The extensor muscle strength was improve in lumbar stabilization exercise(core program) group(p<.05). The trunk flexibility was improve in spinal strengthening exercise group and lumbar stabilization exercise group(p<.05). The balance ability was improve in spinal strengthening group and lumbar stabilization exercise group(core program) group(p<.05). Conclusion: With the above results, demonstrated effects of spinal strengthening exercise and lumbar stabilization exercise in each private guard and security in this study.

Purpose: This research was conducted to compare the effects of a muscle strengthening exercise program on pain, straight leg raising ability, passive range of motion, independent walking time and satisfaction with total knee arthroplasty(TKA). Method: A nonequivalent control group posttest only design was used for this study. A total of 62 patients were randomly divided into the experimental group(31) and the control group (31). The experimental group received a 1-hour exercise intervention, while the control group received the usual care. Data was analyzed by t-test using the SPSS/WIN 11.0. Results: The experimental group showed significant improvement in pain score, straight leg raising ability, passive range of motion of knee joint, independent walking time, and the patient's satisfaction. Conclusion: The muscle strengthening exercise program was effective on decreasing pain and increasing mobility and satisfaction in patients with TKA.

In today's society, the experience of social exclusion caused by being rejected or ignored, leads to negative social consequences, such as aggressive behavior, self-defeating thoughts, and diminished intelligence. This study is performed to examine 1) how two types of social exclusion, rejection and ignorance, affect conspicuous consumption and prosocial behavior and 2) how embodied cognition formed with a firmed muscle moderates their causal relationships. For this purpose, half of the participants in ignorance and rejection conditions were asked to grip their hands to form a firmed muscle (firmed muscle group) while the other half (control group) were not. After the manipulation of embodied cognition, their conspicuous consumption and intention of prosocial behavior were measured. Results show that, in ignorance condition, the firmed muscle group exhibited lower conspicuous consumption and higher intention of prosocial behavior than the control group while, in rejection condition, there were no differences in conspicuous consumption and intention of social behavior between firmed muscle and control groups. Findings indicate that, in the case of social exclusion caused by ignorance, firmed muscle improves self-efficacy, which may increase prosocial behavior.

The effects of dietary supplementation of JR-22, formula containing distilled extracts of traditional herbs on maximal exercise performance and endurance were evaluated in mouse and rat model. In acute forced swimming test with 4%∼8% of the body weight attached to the tail, it was shown that dietary JR-22 supplementation increased endurance in exercise performance. There was no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity, however ATP concentration in muscle was increased by JR-22 supplementation. Also, insulin-like growth factor-l (IGF-1) concentration in blood was significantly increased by JR-22 supplementation. In addition, the oxidative damage induced by exercise was reduced by JR-22 supplementation. In these results, we suggested that JR-22 supplementation enhanced maximal endurance exercise performance by the mechanism of increasing ATP and IGF-1 concentration and reducing oxidative damage.
