In recent years, much evidence has emerged to indicate that exercise can benefit people when performed properly. This reviewsummarizes the exercise interventions used in studies involving mice as they are related to special diseases or physiological status. To furtherunderstand the effects of exercise interventions in treating or preventing diseases, it is important to establish a template for exercise interventionsthat can be used in future exercise-related studies.Methods'. PubMed was used as the data resource for articles. To identify studies related to the effectiveness of exercise interventions for treatingvarious diseases and organ functions in mice, we used the following search language: (exercise [Title] OR training [Title] OR physical activity[Title]) AND (mice [title/abstract] OR mouse [title/abstract] OR mus [title/abstract]). To limit the range of search results, we included 2 filters:one that limited publication dates to "in 10 years,^ and one that sorted the results as "best match^^. Then we grouped the commonly used exercisemethods according to their similarities and differences. We then evaluated the effectiveness of the exercise interventions for their impact on diseasesand organ functions in 8 different systems.Results'. A total of 331 articles were included in the analysis procedure. The articles were then segmented into 8 systems for which the exerciseinterventions were used in targeting and treating disorders: motor system (60 studies), metabolic system (45 studies), cardio-cerebral vascularsystem (58 studies), nervous system (74 studies), immune system (32 studies), respiratory system (7 studies), digestive system (1 study), and thesystem related to the development of cancer (54 studies). The methods of exercise interventions mainly involved the use of treadmills, voluntarywheel-running, forced wheel-running, swimming, and resistance training. It was found that regardless of the specific exercise method used, mostof them demonstrated positive effects on various systemic diseases and organ functions. Most diseases were remitted with exercise regardless ofthe exercise method used, although some diseases showed the best remission effects when a specific method was used.Conclusion-. Our review strongly suggests that exercise intervention is a cornerstone in disease prevention and treatment in mice. Because exerciseinterventions in humans typically focus on chronic diseases, national fitness, and body weight loss, and typically have low intervention com・pliance rates, it is important to use mice models to investigate the molecular mechanisms underlying the health benefits from exerciseinterventions in humans.展开更多

文摘Adolescence is an important stage for brain maturation.To investigate the effect of different exercise doses on inhibitory control in adolescents aged 12 to 14-year old,an after-school exercise program was offered 5 days per week for 12 weeks during a school semester.Thirsty-four adolescents(17 boys)from the first six classes were randomly divided into low-dose exercise group(LE group,one 30-min aerobic exercise bout per day,n=16)and high-dose exercise group(HE group,two 30-min aerobic exercise bouts per day,n=18),while 23 adolescents(10 boys)in the control group(CON,zero 30-min exercise bout,n=23)were from the last two classes.All the participants in different classes received the same physical education with the same contents,duration,and intensity at class.All the participants completed flanker tests and cardiorespiratory tests before and after exercise intervention.The HE group showed more significant improvements on inhibitory control and VO_(2peak)than CON(p<0.05).Changes in physical activity(PA)were significantly correlated with changes in interference scores(Spearman rho=-0.30,p<0.05),VO_(2peak)(Spearman rho=0.31,p<0.05),and BF percentage(Spearman rho=-0.32,p<0.05).This study demonstrated that effect of exercise on inhibitory control in adolescents is dose-dependent,which highlights the need to focus on the exercise dose in daily life for improving cognition among adolescents.
