The program of AER+RES was similar to AER, but went through resistance exercise 20min in base section of every exercise trail.Result: Prior to intervention, adiponectin levels were significantly correlated with BMI、 WHR、 COS、 LN、 LN、 TG、 LG10、 LN、 weight、 waist、 FM、%F, and leptin levels were significantly correlated with BMI、 WHR 、 LN 、 LN 、 TG 、 HDL-C 、 LG10、 apoB 、 apoA1/apoB、 waist、 F1M、%F. Stepwise multiple regression analysis revealed that LG10; COS and waist was an predictor of basal adiponectin levels , and %F,apoB and WHR was an predictor of basal leptin levels. In early obesity, adiponectin and leptin can be worsened , along with the changed of body component, fasting plasm glucose and lipid accumulation. After intervention, both group were significantly reduction in FM,%F,weight, WHR,FPG and TG, while HDL-C had significantly increased.AER exhibited significant in leptin, while AER+RES did not show the change. Insulin and HOMA-IR were changed in both groups. The control group exhibited no significant change in any variables. Although adiponectin levels were unchanged in the three groups, a significant negativecorrelation between delta %F, delta WHR and delta FPG was observed. Futhermore, if compare the degree of delta weight, we fought a significant increased in adiponectin between the group of delta weight higher (=3kg) than delta weight lower(=0kg), delta %F, delta WHR and delta weight were significant negative correlation with delta leptin.

结果：绝经妇女脂联素水平与体重指数、腰臀比、空腹血糖、空腹胰岛素、LEP、TG、极低密度脂蛋白胆固醇、胰岛素抵抗指数、体重、腰围、体脂含量、体脂百分比显著相关；瘦素水平与BMI、WHR、FINS、LEP、TG、HDL-C、VLDL-C、载脂蛋白B、apoA1／apoB、腰围、FM、％F等指标显著相关；多元逐步回归分析显示LG10、COS和腰围是基线脂联素水平的预测变量，而％F，apoB和WHR是基线瘦素水平的预测变量；在肥胖前期，脂联素、瘦素已经出现明显不良变化，同时也伴随着体成分、空腹血糖和血脂的异常；运动实验后，两个运动组的FM、％F、体重、WHR、FPG、TG都显著下降，而HDL-C显著上升；AER组瘦素显著下降，而AER+RES组则没有显著变化；两组的胰岛素和HOMA-IR水平都有显著下降；对照组所有指标都没有明显变化；尽管运动后脂联素水平没有显著变化，但是脂联素变化量与％F、WHR和血糖变化量显著负相关，而且如果按照运动后体重下降的程度比较，则体重下降大(≥3kg)的受试者比下降小的(≤0kg)脂联素水平有明显升高；运动后瘦素水平的变化量与％F，WHR及体重的变化量显著负相关。

The main difference between SH-60B and F is the way they fight against submarines. The B version mainly depends on the sonars on the CG and DDGs to find the targets, then it flies to the suspect area, using 25 tubes sonar buoyages and magnetism detector to make sure the target position for following combat using torpedo. The F is used for short range anti-submarine purpose around the carrier and depends on its own AQS-13F suspensory sonar to detect the submarine.

SH-60B和F型之间的主要区别为他们反潜的方法不同。B型主要依赖巡洋舰和驱逐舰上的声纳发现敌潜艇，然后飞近可疑区域，使用其25管的声纳浮标和磁异常探测器对目标精确定位，随后发起鱼雷攻击。F型则用于航母周围的短距反潜，主要依赖其AQS-13F悬吊声纳探测雷达。
