보행계수기 기반 댄스스포츠 에너지소비량 추정식의 정확성과 노모그램의 제시 = Accuracy of Prediction of Dancesport Energy Expenditure by using a Pedometer and the Proposal of Nomograms

다국어 초록 (Multilingual Abstract)

The purpose of this study is to identify the accuracy of the step unit energy expenditure(cal/kg/step) of sports dancing(Chachacha, Jive) by using a pedometer as developed by Kim et al., (2005), and proposing nomograms. With this aim, the study selected 20 male and female college students in Seoul and the Gyeonggi area by event and by gender through a convenience sample, which totals 80 subjects(average age: 22.1±1.9yr). For a measuring instrument, a pedometer(Yamax SW-650, Japan) and indirect calorimeter(K4b2 Cosmed, Italy) were used, and the actual value was measured with the same procedure employed in the research by Kim et al., (2005). Also, the estimated value was calculated by applying a formula developed by Kim et al., (2005). The collected data was subject to SPSS 12.0, descriptive statistics (M, SD), and Person`s correlation coefficient(r) for confirming the relationship between the actual value and the estimated value of step unit energy expenditure. In order to verify the accuracy of the estimated value against the actual value, the TEM(Technical error of measurement), 95% CI(95% confidence level), and %TEM(relative TEM) were calculated by using MS-EXCEL; and nomograms were proposed by calculating step unit energy expenditure by weight (40kg, 60kg, 80kg, and 100kg). As a result of the research, the estimation formula for the step unit energy expenditure by using a pedometer was proven to overestimate the energy expenditure in general, and the estimation formula of males, particularly for Jive, was proven to have a relatively high accuracy (%TEM=6.57, 95% CI=275.03-357.42 cal/kg/step), whereas the estimation formula of females for Chachacha was proven to have a relatively low accuracy (%TEM=10.17, 95% CI=196.94-297.46 cal/kg/step). Also, the proposed nomograms enabled the estimation of step unit energy expenditure by using kilograms and step count. Therefore, through the results, the estimation formula of Kim et al.,(2005) was found to be relatively accurate, and it is believed to provide an objective estimation of energy expenditure and convenient calculation and give instant feedback through the proposed nomograms.
