영문 초록

The causes of injury in the muscular skeleton system are the impacts. They are divided into the passive impact and the active impact. The passive impact and the active impact are classified by their size(peak) and number. Among the impacts the main cause of acute and chronic injury is the passive impact which is within 50ms and more than 5Hz. Therefore it is necessary to reduce the size and number of this passive impact. It is investigated that the materials of aerobic dance places in Korea are usually wood carpet, laminated paper and concrete. Fortunately the wooden floor is the most common of them. But we can still see many cases that they do aerobic dance on the concrete floor. This fact shows us that they need to have more education and public information. It is found that wood is the best floor material of the aerobic dance places through the experiment of the vertical ground reaction force. Wood is the best material in terms of the size, number and loading rate of the passive impact. It is found that the non-transformational material such as aluminum has a very low impact absorption rate. However, the percentage of doing aerobic exercises on the mattress or the concrete shows 11.5%. We can find by this fact that the possibility of injury is very high. Therefore they need to have the scientific public information, education and regulation. The carpet or laminated paper covered on the non-transformational materials shows that the size, number and loading rate of the passive impact are small. It is necessary to do the impact experiment by investigating what the floor material below the carpet or vinyl laminated paper is and how thick the floor material is. So it is proposed that the impact experiment according to the thickness of the floor material should be done as the following research subject. It is also necessary to investigate what the floor material is in the case of laying the mattress or laminated paper. The mattress or laminated paper cannot absorb the impact effectively if there is non-transformational floor material below it. It can be found through the experiment of the vertical ground reaction force. It is necessary to minimize the impact on one`s muscular skeleton system to continue aerobic dance during his lifetime. Therefore it is necessary to minimize the impact on the muscular skeleton system in the long-term standpoint even though he doesn`t have any pain or injury at the moment. It is recommended to wear the protection belt and the warm clothes to protect the body.
