초록
본 연구의 목적은 국내에서 개발한 무선통신 기반의 심박수측정기 Bodypro_PAPS(DS100; 두성기술, 한국)의 타당도와 신뢰도를 확인하는 것이다. Bodypro_PAPS(DS100)의 타당도를 확인하기 위한 준거장비는 Polar(T-31) 모델을 사용하였고, 연구 목적에 따라 준거장비와 개발장비 두 가지를 모두 피험자에게 착용시킨 후 운동부하검사(Bruce Treadmill Max Protocol)를 실시하였다. 신뢰도 확인은 피험자에게 Bodypro_PAPS(DS100)를 착용시킨 후 통제된 시간과 속도에 따라 2회 반복하여 걷거나 뛰도록 하였다. 연구의 대상은 대전시에 소재하고 있는 D대학교에 재학중인 남녀 학생 총 116명으로 타당도 검사 57명, 신뢰도 검사 59명이 참여하였다. 자료분석은 SPSS 16.0을 이용하여 상관분석을 실시하였고, 이때 통계적 유의수준은 α=.05로 설정하였다. 분석결과 Bodypro_ PAPS(DS100)의 타당도는 시간단위(1분간격)에 따라 r=.702(p=.001)에서 r=.989(p=.001) 사이의 값으로 나타났다. 또한 신뢰도는 시간단위(1분간격)에 따라 r=.511(p=.001)에서 r=.789(p=.001) 사이의 값으로 나타났다. 분석결과 Bodypro_PAPS(DS100)는 심박수측정기로 비교적 높은 타당도를 보였지만, 신뢰도는 중간정도 이상의 수준으로 확인되었다.
Abstract
The purpose of this study was to estimate reliability and validity of Bodypro_PAPS(DS100) which is the wireless heart rate monitor developed by South Korean corporation DU-SUNG technology. The criteria equipment to estimate the validity of Bodypro_PAPS(DS100) was polar(T-31) model, according to the purpose of this study Bruce Treadmill Max Protocol was implemented to subjects equiped both criteria equipment and developed equipment. With equipping Bodypro_PAPS(DS100) to subjects, the experiment with controlled time and speed was implemented twice by walking and running to estimate reliability of developed equipment. The subjects of this study were 116 male and female who were at D university in Daejeon. 57 participated in validity test and 59 participated in reliability test. The correlation analysis was implemented by using SPSS 16.0 to analyse data and the statistical significance level was set with α=0.5. The result of analysis related to the validity of Bodypro_PAPS(DS100) is from r=.702(p=.001) to r=.989(p=.001) according to the estimated time unit(1min). The result of analysis related to the reliability of Bodypro_PAPS (DS100) is from r=.511(p=.001) to r=.789(p=.001) according to the estimated time unit(1 min). The conclusion of this study is that Bodypro_PAPS(DS100) shows high validity relatively but reliability level of Bodypro_PAPS(DS100) is moderate as a heart rate wireless monitor.
