본 연구는 대학축구선수들을 대상으로 12주간의 심리기술훈련과 4주간의 추적조사를 실시하여 경기력결정 심리요인과 운동스트레스 요인의 효과 및 지속성을 알아보았다. 연구대상자는 비 확률표집방법 중 편의표본추출 방법으로 2007년 대한축구협회에 등록된 U대학 축구 부24명(실험집단=13명, 통제집단=11명)이었으며, 연구 참여자의 개인적 특성을 살펴보면 평균연령(19세-22세)은 20세, 경력(7년-13년)은 10년이었다. 본 연구에서 사용한 측정도구는 질적 분석 방법을 위해 면담과 개방형질문지를 사용하였으며, 양적분석 방법으로는 윤영길이 1999년과 2004에 개발한 대학축구선수의 스트레스 검사지와 축구경기력 결정 심리요인 검사지를 사용하였으며 검사지의 타당도는 4개요인과 6개요인 으로 신뢰도는 각각 .817과 .826이었다. 축구선수의 경기력결정 심리요인과 운동스트레스 요인을 비교분석하기 위해 유의수준 .05에서 반복측정 일원분산분석과 심리기술훈련의 지속성을 알아보기 위해 대응표본 t 검증(paired t-test)을 실시한 결과 다음과 같은 결론을 얻었다. 첫째, 대학축구선수의 심리기술훈련을 받고난 후 경기력결정요인이 높아졌다. 둘째, 대학축구선수의 심리기술훈련을 받고난 후 운동스트레스 요인이 낮아졌다. 셋째. 경기력결정 요인의 지속성이 있는 것으로 나타났다. 넷째, 운동스트레스 요인의 지속성이 있는 것으로 나타났다.
The present study investigated effects and durability of the psychological factors of determining performance levels and training-related stress through a follow-up study for four weeks after applying twelve weeks of psychological skill training to the university soccer players. Subjects were 24 soccer players at U university who enrolled at the Korea Football Association in 2007 with convenience sampling out of non probability sampling, among whom 13 were assigned to the experimental group while 11 to the control group. For individual characteristics of the subjects, their average age was 20 (19 to 22) and 10 years of playing experiences (7 to 13 years). Among the experimental group, subjects consisted of three freshmen, three sophomores, five juniors and two seniors. Their positions included one forward, seven mid-fielders, four guards, and one goalkeeper. For the control group, subjects consisted of five freshmen, four sophomores, and two juniors. Their positions included four forwards, three mid-fielders, four guards without any goalkeeper. The present study employed interviews and an open-ended question to elicit the qualitative analysis. Also for quantitative analysis, this study used the stress test for university soccer players and test of the psychological factors of determining soccer performance levels developed by Yoon Young-gil in 1999 and 2004, respectively. The validity of the tests included four factors and six factors, and their respective credibility was .817 and .826. To compare and analyze their psychological factors of determining soccer performance levels and the training-stress factors, One-way ANOVA was used repeatedly measured at .05 levels of significance, and to identify their durability of the psychological skill training, paired t-test was used. Results revealed that statistically significant differences were found in the psychological factors related to performance levels, as well as stress-related factors. The results of the follow-up study also indicated that statistically significant differences existed in both psychological and stress-related factors. It was concluded that the psychological skill training has positive impact on the performance of soccer players.
