[Purpose] To investigate the relation between isotonic leg extension strength (ILES) and the prevalence of metabolic syndrome (MS) in Japanese male adults.[Methods] This cross-sectional study included 395 Japanese men. Metabolic syndrome was determined according to the criteria of International Diabetes Federation (IDF), Japan Society for the Study of Obesity (JASSO), or National Cholesterol Education Program's Adults Treatment Panel III (NCEP-ATPIII). Muscular strength was measured on a horizontal dynamometer. Subjects were divided into tertile levels according to ILES (watts/kg). Multiple logistic regression analysis was used to examine the relation between ILES levels and the prevalence of MS.[Results] The prevalence of MS were 14.4% (IDF), 17.0%(JASSO), and 20.0% (NCEP-ATPIII). After adjustment for confounding factors, the odd's ratios (95% confidence interval) of MS (IDF) compared with the lowest ILES level were 0.90 (0.48-1.68) and 0.31 (0.13-0.64) in the middle and high levels of ILES (p for trend=0.03). The association between the level of ILES and the prevalence of MS by JASSO and NCEP-ATPIIIcriteria were similar.[Conclusion] The prevalence of MS was associated with the level of ILES.
