장기적 과훈련은 경기력 저하는 물론 심리적으로도 부정적인 결과를 초래한다고 많은 연구들은 지적하고 있다. 이에 본 연구에서는 단기적 과훈련에 따른 고등학교 축구선수들의 기분 변화를 조사하여 코치나 감독에게 선수지도에 유용한 정보를 제공하기 위함이다. 이 실험에 참가한 피험자는 25명이 고등학교 축구선수로 평균 운동경력은 3년9개월이었다. 피험자들은 1시간 30분, 3 시간, 그리고 4 시간 30분 조건에서 훈련 전후 측정되어졌다. 각 조건에서 훈련 시 발생했을 피로를 회복시키기 위해 조건간 측정 간격을 48시간으로 하였다. 기분 변화를 측정하기 위해 McAuley와 Courneya(1994)가 만든 주관적 운동 경험 척도(Subjective Exercise Experiences Scale : SEES)를 사용했다. SEES는 (1) 긍정적 행복감(positive well-being), (2) 심리적 부정스트레스(psychological distress), (3) 피로(fatigue) 등 3가지 영역에 12가지 항목을 기초로 하여 만들어 졌다. 본 연구결과 평상시(3시간)보다 훈련 양을 증가시켜 훈련을 시켰을 때 선수들의 심리적 부정 스트레스와 피로가 증가되었고 긍정적인 행복감은 감소되는 것으로 나타났다.
It is well documented that athletes who overtrained definitely experience performance decrements as well as negative training adaptations. Therefore, to improve athletic performance, athletes must be optimally trained. The purpose of this study was to determine the effects of overtraining on the psychological well-being, psychological distress and fatigue of high school soccer players. Twenty-five high school soccer players were participated in this study. Their ages ranged from 17 to 18, with a mean age of 17.2 years, and mean experience of 3 years and 9 months. All subjects participated in three different training session(1 hour 30 min, 3 hours, and 4 hours 30 min) in a row. The interval of each training session was two days. The Subjective Exercise Experiences Scale(SEES) was administrated to measure subjects` mood alteration before and after each training session. The results of this study indicated that subjects in the 4 hours and 30 min overtraining condition showed more increments in fatigue and psychological distress than the rest of two conditions. The results of this study also indicated that mood disturbance which may be a potential factor influencing performance increased significantly as the training load increased. Psychological responses to overtraining results in negative effects. The present study suggests that in order to improve athletic performance, coach should understand the negative effects of overtraining in terms of psychological functioning.
