抄録 <p>We investigated the link between changes in body composition and the blood pressure (BP) response to exercise in overweight Japanese by a retrospective clinical study carried out over a 3-year period. We analyzed data for 38 overweight Japanese aged 22-69 years (47.8 +- 11.4) at baseline. Among the participants, 32 overweight subjects (body mass index : BMI, 29.0 +- 3.0 kg/m2) were further analyzed with a 3-year follow up. BP at rest, the BP response to an exercise test, the aerobic exercise-level determined ventilatory threshold (VT), and body composition were evaluated at an interval of 1 year. During the study period, there were 6 drop outs, who started to receive anti-hypertensive drugs because of the development of hypertension. Based on analysis of follow up data, parameters of body composition were significantly reduced over the 3 years. Systolic BP (SBP) at rest and at VT was also reduced. In addition, delta SBP (? : delta represents positive change in parameters) at VT was positively correlated with ?parameters of body composition over the 3 years. In overweight subjects with increased body weight, there was a significant time (pre vs year 3) effect and interactions by 2 factor-factorial ANOVA. The present study indicates that changes in body composition are closely linked to the SBP response to an exercise test. </p>

抄録 <p>We compared the levels of hepatic enzymes in 220 Japanese men with metabolic syndrome with those in age and sex-matched subjects without the syndrome. Metabolic syndrome was defi ned by the new criteria published in Japan, and hepatic enzymes, i.e., aspartate aminotransferase (AST), alanine aminotransferase (ALT) and &#947;-glutamyl transpeptidase (&#947;GTP), were measured. AST, ALT and &#947;GTP in subjects with metabolic syndrome were signifi cantly higher than those in subjects without the syndrome, and metabolic syndrome was closely associated with hepatic enzymes in this cohort of Japanese men.</p>

抄録 We re-evaluated the criteria for waist circumference to predict the accumulation of the components of metabolic syndrome. We used data for 3,185 Japanese, aged 20-79 years. Metabolic syndrome has recently been redefined by a new criterion in Japan, in which waist circumference cutoff points, i.e. 85 cm for men and 90 cm for women, are employed. Among the 3,185 Japanese considered in the present study, 335 men (26.8%) and 69 women (3.6%) were diagnosed as having metabolic syndrome. A cutoff point as a predictor for 2 or more components of metabolic syndrome was evaluated by sensitivity/specificity and a receiver operating characteristic (ROC) curve. The optimal point was estimated as being approximately 85 cm of waist circumference in men and 75 cm in women. We therefore recommend a cutoff value, 75 cm of waist circumference, for the criterion of metabolic syndrome in women.

抄録 <p>We evaluated the linkage between oxygen uptake at the ventilatory threshold (VT) and muscle strength in subjects with and without metabolic syndrome. We used data of 226 Japanese men with metabolic syndrome and 265 Japanese men without the syndrome. Metabolic syndrome has recently been defined by a new criterion in Japan. Oxygen uptake at VT and muscle strength, i.e. grip strength and leg strength were measured. Oxygen uptake at VT and muscle strength/body weight were found to be significantly lower in subjects with metabolic syndrome than in those without the syndrome. However, the differences did not reach significant levels after adjusting for leg strength/body weight or oxygen uptake at VT. A combination of aerobic exercise and resistance training might be considered for preventing and improving metabolic syndrome.</p>

抄録 <p>We compared muscle strength between Japanese men with and without metabolic syndrome. We used data for 323 Japanese men with metabolic syndrome and 893 Japanese men without the syndrome. Metabolic syndrome was defined by a new criterion in Japan, and the parameters for muscle strength, i.e. grip strength, leg strength were measured. Leg strength was found to be significantly higher in subjects with metabolic syndrome than in those without, while muscle strength per body weight was significantly lower in subjects with the syndrome. Lower muscle strength per body weight may be one of the characteristic features in subjects with metabolic syndrome.</p>
