The purpose of this study were to describe and compare the selected electromyographical muscle activities of body during the Dance sports Tango Through over sway movement. Using surface electrode, we evaluated muscle activity in 4 male Players and Amateur dancers during a Tango Through over sway movement. Surface electrodes were used to record the level of muscle activity in the Trapezius, Erector spinae, Vastus lateralis, Gastrocnemius. These signals were compared with %RVC(Reference voluntary contraction) which was normalized by IEMG(Integrated EMG). we observed patterns of selected muscle activity throughout five phases of the Through over sway movement. The Through over sway movement results can be summarized as follows: LTP, RTP, LVL, RVL, LGCM, had statistically significant difference in 1st phase, LTP, RTP, LES, RES, RVL had statistically significant difference in 2nd phase, LTP, LVL, RGCM had statistically significant difference in 3rd phase, RTP, LVL, RVL had statistically significant difference in 4th phase, RTP, LES, LVL, RVL, RGCM had statistically significant difference in 5th phase, The results can also help in injury prevention, and rehabilitation of the players through the analysis of the muscle activity when performing a Through over sway Tango. In addition, there is thought to be helpful in basic materials and guidance and training to perform the appropriate action amateur.

Este trabajo intenta ofrecer la poli´tica cultural de la dictadura militar argentina a partir del an~o 1976. Con la finalidad de estudiar las relaciones del Proceso de Reorganizacio´n Nacional con la literatura y la cultura argentinas de la e´poca, se ha tomado conciencia del hecho de que sen~alar so´lo a los militares como responsables de la poli´tica cultural distorsiona el ana´lisis, dado que el hecho histo´rico de la dictadura militar se origino´ tanto en los militares como en sus grupos de apoyo. Adema´s de utilizar te´cnicas represivas para aterrorizar al pueblo, la dictadura utilizo´ un discurso que intento´ justificar sus acciones. Este discurso fue acompan~ado por otro creado por los intelectuales que favoreci´an el gobierno militar. Este u´ltimo discurso fue aqui´ denominado `discurso de apoyo`. El impacto de la dictadura sobre la cultura y la literatura argentinas abarco´ no so´lo las muertes, desapariciones y exilios, sino tambie´n el elogio a los escritores consagrados, la difusio´n de la ideologi´a del gobierno militar a trave´s de las notas periodi´sticas, la negacio´n de los escritores `jo´venes`, y la promocio´n de best-sellers propicios al discurso del poder. Hacia 1980, no so´lo comienzan a surgir ejemplos de una literatura de resistencia, sino tambie´n un vasto pu´blico interesado en la literatura nacional. Se puede afirmar entonces que si bien la dictadura triunfo´ a corto plazo, despue´s de cuatro an~os de silencio, a partir de 1980 la literatura argentina vuelve a mostrar su vitalidad y el pu´blico su intere´s por ella.

The purpose of this study was to investigate the muscle mechanics of shoulder injury in female professional golfers. The golf swing of 10 KLPGA professional golfers was compared and analyzed with swing data with information about shoulder impaired and absent. The total 10 subjects including korea ladies professional golf association were selected for the study. The following conclusions by analyzing swing data during the golf drive & iron swing of ladies professional golfers. In the Shoulder injury and not according to the data analysis of the driver & iron Swing. it showed a statistically significant from club head speed, height, landing angle, carry, attack angle, launch angle & hang time. These results shown that Shoulder injury of ladies professional shows significant results in most of the swing data variables. It is shown that the rehabilitation of the damage to the shoulder required. In the future, the data will be analyzed for the damaged area of ladies professional golfers in the muscles around the spine. The data will be helpful in injury prevention and rehabilitation of athletes. Suggest a balanced look to the future of the whole muscle mechanism swing.

The purpose of this study was to analyze the muscle activities in golf approach of professional & amateur golfers, and provide the guideline of training in golf approach. Using electromyography (EMG), we evaluated muscle activities in 11 professional & 11 amateur golfers during golf approach swing. Surface electrodes were used to record the level of muscle activities in the Extensor carpi radialis longus (ECRL), Brachioradialis (BR), Palmaris longus (PL) muscles during the swing. These signals were compared with %RVC(Reference voluntary contraction) which was normalized by IEMG (Integrated EMG). The approach swing were divided into three phases: Back swing, Down swing, Follow through phase. The results can be summarized as follows; there were significant increase of left PL muscle in pro golfers during back swing of 15m approach shot (p<0.05). There were significant decrease of right ECRL muscle in pro golfers during down swing of 50m approach shot (p<0.05). There were significant decrease of left PL and right BR muscles in pro golfers during follow through of 30 m shot, while significant increase of left BR muscle during follow through of 50 m shot (p<0.05). The results showed that the approach swing should require a controlled force in forearm and smoothing swing.
