코어 트레이닝(Core Training) 효과에 관한 메타 분석적 접근

국문 초록 (Abstract)

본 연구는 코어 트레이닝 효과를 종합하기 위하여 기존 선행연구를 수집한 뒤 메타분석을 적용하였다. 이를 위해 13편의 논문을 중심으로 체계적 문헌 고찰과 메타 분석적 접근을 수행했다. 분석결과를 중심으로 내용을 기술해보면 다음 과 같다. 첫째, 전체 효과 크기를 분석한 결과 Hedges’ g 값은 .713으로 나타났다. 둘째, 코어 트레이닝이 남녀 집단 모두에 서 효과적임을 입증하였다. 셋째, 질환 여부에 따른 효과차이 검증 결과 두 집단 간 효과크기의 차이는 통계적으로 유의미 하였다. 넷째, 참여 빈도에 따른 효과차이 검증 결과 참여 빈도가 증가하면 코어 트레이닝의 효과가 더욱 증가한다는 것을 확인하였다. 다섯째, 참여시간을 독립변수로 효과크기를 종속변수로 설정한 뒤 메타-회귀분석(meta-regression)을 실시한 결과 참여시간의 증가는 효과크기에 유의한 영향을 미치지 않는 것으로 나타났다.

In order to put together the effects of core training, this study collected the existing preceding researches, and then applied the meta-analysis. For this, after going through the PICO set-up process, this study performed the systematic literary review and meta-analytic approach focusing on total 13 theses. The results of the analysis could be described as follows. First, in the results of analyzing the overall effect size, the Hedges’ g value was .713. Second, in the results of verifying the effect differences between sex, the effect size of men was .798 while the effect size of women was .709. The difference in effect size between two groups was not statistically significant, which verified the effects of core training on both groups of men and women. Third, in the results of verifying the effects according to the matter of disease, in case when there was a specific disease, the effect size was .358. When there was no specific disease, the effect size was .765. The difference in effect size between two groups was statistically significant. Fourth, in the results of verifying the effect differences according to the frequency of participation. in case of three times a week, the effect size was .703. In case of four times a week, the effect size was 1.516. The difference in effect size between two groups was statistically significant. This verified that the effects of core training would be more increasing when the frequency of participation increased. Fifth, in the results of conducting the meta-regression analysis after setting up the participation hours as an independent variable and the effect size as a dependent variable, the increase of participation hours did not have significant effects on the effect size.
