운동은 심혈관계 위험 인자인 총 콜레스테롤, 저밀도 지단백 콜레스테롤, 중성지방을 감소시키고, 고밀도 지단백 콜레스테롤을 증가시켜 심혈관계의 순환을 도와 심혈관질환 예방에 도움을 준다 전신진동운동은 비교적 최근의 운동방법으로 다양한 관점에서의 적용이 요구된다. 따라서 본 연구에서는 전신진동운동이 심혈관 질환의 예방에 미치는 영향을 살펴보고자 하였다. 본 연구를 위해 6주령 된 Sprague-Dawley female을 이용하였으며, 1주간의 예비사육기간을 통해 환경적응을 시켰다. 실험동물은 3 그룹, 즉 baseline(n=9), control(n=9), WBV exercise(n=8)으로 나누었다. 전신진동운동은 45Hz, 0.3g(g=9.8m/s2)의 강도로, 주5일, 6주 동안 수행하였다. 진동운동이 심혈관건강 상태를 추정하는 혈중지질성분 (TG, TC, HDL-C, LDL-C, FFA, non-HDL-C)을 집단간에 비교하였다. 집단간 비교를 위해 처치집단(baseline, control, WBV exercise)에 따른 변인(factor)의 차이는 one-way ANOVA를 이용하였으며, 통계적으로 유의한 효과가 나타난 변인에 대한 사후검정(post-hoc)은 LSD법을 이용하였다. 통계적 유의수준은 p<.05로 설정하였다. 연구결과 전신진동운동 유무에 따른 집단간 차이는 TC와 non-HDL-C에서만 유의한 차이가 있었다. 전신진동운동 집단은 control 집단에 비해 TC 수준이 유의미하게 낮게 나타났으며(p=.031), non-HDL-C 역시 전신진동운동 집단이 control 집단에 비해 통계적으로 유의미하게 낮은 수준을 보였다(p=.019). 본 연구내용을 정리해 보면 전신진동운동이 혈중지질성분의 긍정적인 변화에 영향을 미치는 것은 맞지만 월등하게 심혈관계질환을 예방할 만큼 변화시킨다고 하기에는 운동으로서의 효율성이 낮다고 사료된다.

This study verifies the goodness-of-fit of the leisure sports safety awareness scale to which Rasch model was applied. For this purpose, a total of 651 university students were selected as samples from Seoul, Gyeonggi, and Chungcheong provinces. The validity and reliability of the leisure sports safety awareness scale developed by Kim and Kim(2017) were first confirmed before the collected data was verified by applying a total of 13 questions minus one question. The conclusion obtained as such is as follows: The five questions that were determined to be inadequate were deleted. The reliability index was found to have no problem, whereas the five-point question-response types fell into a proper criterion with order arrangement pattern. However, question No. 10 showed a limitation as to be applied as a common question since it turned up differentiated responses depending on the gender of the respondents. Therefore, it was concluded that it is appropriate to present the results of the leisure sports safety awareness scale applicable to university students via the Rasch model, by using 3-factor, 8-question and 5-point response scale.
