무용에 있어서 스트레칭의 원리와 방법에 관한 연구

다국어 초록 (Multilingual Abstract)

The main purpose of this study is to provide dancers with a theoretical basis on stretching techniques available during exercise in order to improve their flexibility effectiviely and prevent them form potential factors of dance injury. The topics of the study are examined in relation to biophysical aspects of stretching, principles of stretching, and methods of stretching. The results obtained from this study are as follow as;

1. Connective tissues respond to stretch in a viscoelastic manner. This property of connective tissue and the contract/relax properties of muscle determine response to stretching. Stretching program requires at least training for 8 weeks.
2. The basic principles of stretching are: warm up prior to stretching, stretch before and after dance class, stretch gently and slowly, and stretch to the point of tension but never pain.



3. The stretching options available can be divided into three categories: static, ballistic, and PNF stretching. The static stretching is recommended for preparticipation exercise in combination with warm-up. It produces the least amount of tension of different types of stretching and is probably the safest and the easiest method of increasinf flexibility. The ballistic stretching employs the rapid application of force in a repeated manner on bouncing. The rapid increase in force can cause injury and is causes a reflex muscle contraction and may impair stretching activity. The PNF stretching is performed by alternating contraction and relaxation of both agonist and antagonist muscles. It is thought that PNF stretching produces greater flexibility than the other stretching techniques.
