Abstract
vPURPOSE: Cardiorespiratory fitness is closely related to cardiovascular and chronic diseases and is an important predictor of mortality. Despite the significance of cardiorespiratory fitness, currently, a lack of research exists that validates the effectiveness of the 6-minute walk test, specifically in the Korean population. Therefore, the purpose of this study was to verify the validity of the 6-minute walk test for Korean older individuals and to develop a maximum oxygen consumption (VO<sub>2max</sub>) prediction equation.METHODS: A total of 167 participants were included in the final analysis, after excluding 33 of the 200 participants. Moreover, VO<sub>2max</sub> was measured by performing a submaximal exercise test on a treadmill, and the total distance and heart rate were measured using a 6-minute walk test. Pearson’s correlation coefficient was calculated to verify the criterion validity between VO<sub>2max</sub> and total distance in the 6-minute walk test. To develop a VO<sub>2max</sub> prediction equation, multiple regression analysis was conducted and cross-validation of the developed prediction equation was confirmed.RESULTS: The correlation coefficient between VO<sub>2max</sub> and the 6-minute walk test was 0.575 (<i>p</i><.001). The adjusted R2 of the VO<sub>2max</sub> prediction equation using the 6-minute walk test was 0.449 (<i>p</i><.001). The difference between the predicted VO<sub>2max</sub> and measured VO<sub>2max</sub> was 1.184±1.331 mL/kg/min, and the correlation coefficient was 0.594 (<i>p</i><.001).CONCLUSION: The developed prediction equation consisted of explanatory variables that can be measured easily and were practical in the field. As entry into a post-aged society is imminent, managing older adult’s physical fitness has become a significant issue. In the future, if the validity verification is performed with a large number of people, the prediction formula developed in this study will be useful.
