寒冬之夜,走街串巷叫卖烤红薯的声音给人留下难忘的印象,这是日本自古以来流行的风味小吃。“烤红薯好吃,但会使人发胖,只好不吃”,“很想吃,但不敢吃,忍着点儿吧!”——这是妇女们常说的话。可见,烤红薯被看成是“使人发胖的食品”了。实际上,烤红薯并不会使人发胖,相反却是使人变瘦的食品。为什么这样说呢?请看事实:100克红薯含123卡路里热量,而100克白米饭则产生356卡路里,可见红薯所含热量不过是米饭的三分 相似文献

人到三、四十岁会自然发胖,原因虽多,但代谢率的下降是一重要的内在因素。如以25岁左右的人为标准,30～40岁时的热能消耗要下降3%,40～50岁时要下降6%。消耗下降,而食欲不减,则剩余热量便转化为脂肪存储于皮下,这时血中脂肪含量也会上升。妇女由于内分泌的影响,发胖的倾向 相似文献

运动干预后肥胖青年女性RBP4与GLUT4mRNA表达的相关性研究 总被引：1，自引：0，他引：1
目的：探索运动后肥胖青年女性血清视黄醉结合蛋白4（RBP4）与葡萄转运体（GLUT4）的关系。方法：肥胖青年女性随机分为运动组和对照组，运动组进行12周慢跑锻炼，检测BMI、体脂率、血清RBP4、胰岛素和单核细胞GLUT4mRNA表达水平。结果：运动组肥胖青年女性血清RBP4、BMI、体脂率、胰岛素水平显著降低，单核细胞GLUT4mRNA表达水平显著增加，胰岛素敏感性提高。结论：12周慢跑能够通过降低肥胖青年女性血清RBP4、BMI、体脂率、胰岛素水平，增加单核细胞GLUT4mRNA表达水平，提高胰岛素敏感性；RBP4与单核细胞CLUT4mRNA表达呈负相关。 相似文献

The purpose of this investigation was to determine the effect of a combined strength and aerobic conditioning program on the ability of college-age women to perform the pull-up exercise and to identify the characteristics of women successful in performing a pull-up at the end of the program. Participants significantly increased upper body strength and fat-free mass and deceased fat mass and percentage of body fat. Participants successful at performing a pull-up had significantly greater 1 repetition maximum strength, strength to mass ratio, and strength to fat-free mass ratio. A two variable equation (% body fat and strength to fat-free mass ratio) was developed to predict which women would be successful at completing a pull-up at the end of a similar training program. 相似文献

The purpose of this study was to determine the extent to which the mean difference in performance between men and women on selected physical performance tests was related to the sex difference in body fatness. Percent total body fat (% fat) estimated from skinfold thickness measures and performances on the modified pull-up, vertical jump, 50-yard dash, and 12-minute-run tests were measured on 55 male and 55 female college students. Males had significantly less fat and performed significantly better than females on each of the performance tests. Mean differences were 8.2% fat, 20.0 modified pull-ups, 20.8 cm on the vertical jump, 1.3 seconds on the 50-yard dash, and 590 m on the 12-minute run. Linear regression equations predicting performance scores from % fat within the groups of men and women indicated that if body fatness in men and women were similar, performance differences would be reduced, on the average, by 7 modified pull-ups, 4 cm on the vertical jump, .5 seconds on the 50–yard dash, and 146 m on the 12-minute run. These expected changes in performance were 36%, 19%, 38%, and 25% of the mean sex difference in performance on the four physical performance tests, respectively. It was concluded that greater body fatness is one characteristic that partly explains why women, on the average, do not perform as well as men on strenuous tasks requiring movement of the body weight. The sex-specific difference in body fatness should be one factor considered in establishing separate occupational and athletic performance expectations for men and women. 相似文献

The aims of the present study were to assess the maximal oxygen uptake and body composition of adult Chinese men and women, and to determine how these variables relate to age. The cross-sectional sample consisted of 196 men and 221 women aged 20 - 64 years. Maximal oxygen uptake (VO2max) was determined by indirect calorimetry during a maximal exercise test on an electrically braked cycle ergometer. The correlations between VO2max and fat mass were -0.52 in men and -0.58 in women. Linear regression defined the cross-sectional age-related decline in VO2max as 0.35 ml kg(-1) min(-1) year(-1) in men and 0.30 ml kg(-1) min(-1) year(-1) in women. Multiple regression analysis showed that more than 50% of this cross-sectional decline in VO2max was due to fat mass, lean mass, and age. Adding fat mass and lean mass to the multiple regression models reduced the age regression mass from 0.35 to 0.24 ml kg(-1) min(-1) year(-1) in men and from 0.30 to 0.15 ml kg(-1) min(-1) year(-1) in women. We conclude that age, fat mass, and lean mass are independent determinants of maximal oxygen uptake in Chinese adults. 相似文献

Abstract In this study we determined the exercise intensity that elicits the highest fat oxidation rate in 15 obese women and 13 obese men. Furthermore the relationship between this intensity with the lactate (LT) and ventilatory thresholds (VT) was investigated in order to give training recommendation for maximal fat utilization during endurance exercise. After an incremental exercise test until exhaustion on a cycle ergometer, subjects performed six 20-min exercise bouts of 25, 35, 45, 55, 65 and 75% VO2peak. The 20 min stages were randomly assigned and spread over two separate occasions (three bouts per occasion). Substrate oxidation was measured with indirect calorimetry and was calculated using stochiometric equations. In both, women and men the highest fat oxidation rate occurred at 65% VO2peak and this did not coincide with either the VT or LT. A significant correlation between VT and LT could not be found in women (r=0.33) nor men (r=0.277). In obese women and men training recommendation for maximal fat utilization should not only be given by the intensity at which AnT occurs. 相似文献
