(Research Objective) Suspension Training is a core part of the development of human strength and improve muscle control, an effective way to prevent sports injuries, many sports projects to benefit from the suspension of training. Adding suspension training content in conventional strength training program, strength training observed this way special student sports colleges Triple Jump abdomen, back muscle strength training affect the results, thereby exploring whether training can improve suspension Triple Jump sports college Majors abdomen, back muscle strength. In addition, through research, special institutions for the triple jump sports physical training of students new ways to gain. Research MethodsIn this paper, literature, expert interviews, questionnaires, statistics and experimental research on these issues are analyzed in this experiment Capital Institute of Physical Education sports Training Department 2011 special eight boys triple jump as experimental subjects, experimental subjects were two national athletes, according to test data before the experiment, the subjects were divided into experimental and control groups, for eight weeks of training. Control group front and the traditional model of muscle strength training, suspension training the experimental group added in the training process. Research Results Both groups and the maximum static strength occurred rapidly than before to experiment with different degrees of change, the experimental group showed maximum static strength more substantial and rapid improvement in the control group subjects have not been significantly improved, two group, the difference was significantly（P ＜0.05）. Suspension training can effectively enhance the triple jump special student abdomen, back muscle strength: two subjects crunches, sit two onwards, supine leg raise, after the prone back extension, prone two values are compared from five significant changes（P ＜0.01） occurred before the experiment.

Diet restriction and exercise alleviate cognitive reduction of high fat diet(HFD)-induced obese mice by rescuing inflammation-mediated compromised insulin signaling pathway through activating AMPK/SIRT1 signal pathway and suppressing TLR4 signal pathway

作者： Hu Zhang Ye Zhang Jiling Liang Jiahang Li Miao He Xin Liu Jielun Huang Minghui Wang Jingjing Fan Ning Chen Tianjiu Research and Development Center for Exercise Nutrition and Foods， Hubei Key Laboratory of Exercise Training and Monitoring， college of sports Medicine， Wuhan sports University Physical Education Institute， Hubei University of Science and Technology

Obesity， caused by excessive energy， leads to body weight gain and various diseases， including cognitive impairment. Current studies suggest that diet restriction such as optimal fasting and regular exercise are crucial for improving cognitive capacity. However， further exploration is needed to understand the specific mechanisms of high fat diet (HFD)-induced cognitive decline in obesity. In the present study， 4-month-old mice were subjected to HFD feeding for 18 weeks， followed by aerobic exercise and high-intensity intermittent exercise， regular diet feeding， and intermittent fasting for 8 weeks， and then used to evaluate cognitive capacity， inflammation， compromised insulin signaling pathway， oxidative stress， and apoptosis in hippocampal tissue， as well as AMPK/SIRT1 and TLR4 signal pathways. Obese mice revealed impaired cognitive capacity as compared with mice fed with regular diets. In contrast， aerobic exercise， high-intensity intermittent exercise， regular diet， and intermittent fasting could inhibit apoptosis caused by inflammation-mediated compromised insulin signaling pathway in hippocampal tissues through activating the AMPK/SIRT1 signal pathway and suppressing the TLR4 signal pathway， thereby rescuing the cognitive impairment of obese mice. Therefore， diet restriction and exercise interventions may play a positive role in reverting obesity-induced cognitive impairment.
