The purpose of this study was analysis of physiological and psychological factors to over-practice syndrome for korea dancer. This study was to investigate the changes of physiological factor(weight, HR, BP, and maximal exercise time), information processing ability(RT and ART), physical fitness, energy substrate(blood glucose, lactate, LDH, and CK), stress hormone(norepinephrine, and cortisol), and emotion(profile of mood state) following performance schedule. The subject were 16 korea dance company in cheong-ju city. Over-practice program following performance schedule were composed of baseline practice phase(-D20, 20day before performance), over-practice phase(-D10, -D1; 20 and day before performance), recovery phase(+D1, +D2; 1 and 2day after performance). Blood samples was drawn from antecubital vein in resting. All data were analyzed by one-way ANOVA on of SPSS, accepting level for all significances was above α=.05. The results were summarized as follows: 1. The changes of weight and maximal exercise time following over-practice were significantly decreased. 2. The changes of information processing ability(RT, ART), and physical fitness were no significantly differences. 3. The changes of blood lactate, CK, and LDH following over-practice were significantly differences. 4. The changes of stress hormones(NE, cortisol)were significantly differences. 5. The changes of psychological emotion factors(tension and fatigue) were significantly differences. In conclusion, these indexes(weight maximal exercise time, blood lactate, LDH, CK, NE, and cortisol) were proposed as markers of for diagnosis of over-practice. Namely, over-practice induced harmful effects on weight, performance, energy substrate, stress hormone, and factors. Therefore, this results suggested that over-practice has associated with decreased performance capacity in dancer.

본 연구는 공연 준비 과정에서 무용수들의 과다연습으로 인한 부작용을 분석하기 위해 과다연습 증후군 지표에 대한 심리적 요인을 분석하였다. 이를 위해 공연 일정 (-D20, -D10, -D1, +D1, +D2)에 따른 무용수들의 심리적 요인, 즉 심리적 정서상태 (POMS)를 분석한 그 결과 다음과 같은 결론을 얻었다. 공연일정에 따른 무용수의 심리적 정서 변화에서 긴장감(tension), 피로감(fatigue) 항목은 과다 연습에 의해 유의한 증가를 보였지만(p < .05), 우울감(de- pression), 노여움(anger), 활력감(vigor), 혼돈감 (confusion) 항목은 유의한 변화가 없었다(p>.05). 이상 같이 공연 준비 과정에서 대부분의 무용수들이 과다연습에 노출되어 있으며, 피로와 스트레스가 누적되어 있다는 것을 알 수 있었다. 즉, 과다연습에 의한 심리적 변인(POMS) 중 긴장감, 피로감 항목은 과다연습 증후군의 지표로서 이용될 수 있으며, 이런 항목들은 무용 현장에서 무용수들의 컨디션을 평가할 수 있는 지표로 활용될 수 있을 것이다. 특히 공연 준비 과정에서 지속적인 무용수들의 과다 연습은 무용수들 에게 긴장고조 및 스트레스 유발에 따른 무용수행력 저하는 물론 만성 피로와 스트레스성 면역질환을 초래할 수 있을 것이다.
