Abstract

The purpose of this study was to analysis the effect of form of outsole - complex function double rocker sole(CDR) vs. negative-heel rocker sole (NR) - on energy consumption and heart rate intensity during gait. 11 women, who had no medical history on musculoskeletal disease and surgery within 3 years prior to study, were participated. The walking energy cost per time (WECt) during 35minutes, heart rate intensity, and total calorie consumption were compared by using pair t-test. The WECt and total calorie consumption were found to be significantly higher(p<.05) in CDR than NR. However, there was no difference in HRi. Based on the present study, CDR shoe may have significant implications in shoe prescription for people who want to increase energy consumption.

본 연구에서는 double rocker sole을 채용한 기능성(complex function double rocker sole; CDR) 신발과 negative-heel rocker sole(NR)을 채용한 신발의 보행 중 에너지 소비량을 비교하여 보행시 에너지 사용을 증가시킬 수 있는 기능성 신발에 대한 기초자료를 제공하고자 하였다. 이를 위해 2011년 3~8월까지 40~50대 중년여성 11명을 대상으로 inbody 4.0 (Biospace, Korea)로 체성분 검사와 Vmax ST(SensorMedics, USA)로 운동부하 심폐기능 검사를 실시한 후, 분당 보행에너지 소비량(walking energy cost per time; WECt)과 심박수 운동강도(Heart rate intensity; HRi)를 산출하였다. 연구 결과, CDR신발은 NR신발에 비하여 심박수 운동강도의 통계적 유의차 없이 분당 보행에너지 소비량과 총 칼로리 소비량이 높게 나타나, CDR신발은 동일한 운동 조건 속에서 자각적 운동강도를 증가시키지 않고 운동량을 증가시킬 수 있으므로 에너지소모량을 높이고자 하는 사람에게 적합할 것으로 생각된다.
