Association between cardiorespiratory, muscular fitness and metabolic syndrome in Korean men

Abstract

AimsCardiorespiratory and muscular fitness (CRF, MF) are independent predictor of metabolic syndrome (MS). The purpose of this study was to investigate the association between CRF, MF and MS in male adults. MethodsData collected from 10,774 males who visited the National Fitness Center between 2002 and 2009. The data included measurements of subjects' blood pressure, HDL-cholesterol, triglycerides, body mass index, CRF (VO2max), MF (grip strength, push-up, sit-up, knee joint strength). CRF, MF level was classified into three tertiles. ResultsAs for the prevalence rate according to CRF level, the differences between groups were 47.6% of the low CRF group, 33.1% of the middle CRF group, and 19.3% of the high CRF group were found to have MS. As for the MS prevalence rate according to MF level, the differences between groups were 47.1% of the low, 31.8% of the middle, 21.1% of the high MF group were found to MS. It was found that MS odds ratios (OR, 95% confidence interval) decreased as the CRF levels improved; as indicated by OR = 0.64 (0.57–0.72) in the middle CRF, OR = 0.36 (0.31–0.41) in the high CRF. As for MF, the middle MF, OR = 0.62 (0.55–0.70), the high MF, OR = 0.40 (0.35–0.45) were lower than that of the low MF. ConclusionThe level of CRF, MF has association with MS in men. This study suggests that we need to manage our fitness to prevent MS.
