摘要：Woolf-May K, Scott A, Kearney E, Jones DW. The Effects of 24 Weeks of Moderate Intensity Walking upon Metabolic Syndrome Risk Factors in Previously Sedentary/Low Active Men. JEPonline 2011;14(4):145-156. This study determined the effects of 24 weeks of walking on risk factors and insulin sensitivity associated with metabolic syndrome (MetS) in men. Forty-eight (28.4±3.2 BMI) sedentary/low-active men were randomly selected into controls (n=19, 52.4±8.0) or walkers (n=29, 54.9±8.0 yrs). Over a 24-week period, 156.4±26.5 min·walking·wk-1 was performed in 7.2±2.9 sessions·wk-1 for a mean of 25.1±10.3 min·session-1 at an estimated relative VO2 max of 50.6±9.1%. GLM statistical analysis using the baseline values as a covariate was employed. Bonferroni correction set significance at P<0.0001); waist/hip (W/H) ratio (-0.02 ±0.03 vs. +0.01±0.03, P<0.0001), serum insulin (-1.7±1.5 vs. +2.0±6.0, P<0.002); ISI negatively with WC (R=- 0.433; P<0.003), indicating the changes in body composition to have affected insulin metabolism and insulin sensitivity. The men who walked at an easily attainable intensity for most mobile adults of ~51% of relative VO2 max showed reduced WC and enhanced insulin sensitivity, thus reducing their risk of MetS and type II diabetes.
