中国与国际奥委会关系探析:历史、现状与展望

随着中国体育事业发展和多边外交推进,中国与国际奥委会的关系也备受瞩目。从国际组织研究视角切入,运用历史分析法和演绎推理分析法深入阐述了中国与国际奥委会关系。研究认为:中国与国际奥委会关系可以划分为初次接触、曲折前行和从关系破裂到全面合作3个主要阶段。双方在新时代的互动关系推动了中国特色大国外交、促进了中国体育事业和经济发展、扩大了奥林匹克运动在中国的普及和传播。建议中国积极参与全球体育治理,培养国际组织人才以及拓展合作领域、服务国家外交大局。     

5~18岁儿童青少年24 h活动研究:现状、影响因素与健康效应

目的:对5~18岁学龄期儿童青少年的24 h活动研究进行系统综述,总结并归纳现有文献报道的研究特征、研究方法与研究结果。通过系统检索,共有20篇文献纳入本综述,结果发现,平均30.84%、41.32%、45.04%的儿童青少年分别达到了身体活动、屏幕时间、睡眠时长3项指标推荐量,17.56%、46.16%、35.06%、6.85%的儿童青少年分别达到了0、1、2、3项24 h活动指标推荐量。男生的身体活动达标率优于女生,但男生屏幕时间指标达标率普遍低于女生。随着年龄的增长,屏幕时间的达标率显著降低。父母教育程度越高,其子女的24 h达标条数越多。并且,纳入的研究一致发现24 h活动的指标多项达标可以改善儿童青少年不同的健康指标,包括体重状况、心血管健康、心理状况、认知发展、生活质量以及饮食模式。

Animal exercise studies in cardiovascular research: Current knowledge and optimal design—A position paper of the Committee on Cardiac Rehabilitation,Chinese Medical Doctors’ Association

Growing evidence has demonstrated exercise as an effective way to promote cardiovascular health and protect against cardiovascular diseases However, the underlying mechanisms of the beneficial effects of exercise have yet to be elucidated. Animal exercise studies are widely used to investigate the key mechanisms of exercise-induced cardiovascular protection. However, standardized procedures and well-established evaluation indicators for animal exercise models are needed to guide researchers in carrying out effective, high-quality animal studies using exercise to prevent and treat cardiovascular diseases. In our review, we present the commonly used animal exercise models in cardiovascular research and propose a set of standard procedures for exercise training, emphasizing the appropriate measurements and analysis in these chronic exercise models. We also provide recommendations for optimal design of animal exercise studies in cardiovascular research, including the choice of exercise models, control of exercise protocols, exercise at different stages of disease, and other considerations, such as age, sex, and genetic background. We hope that this position paper will promote basic research on exercise-induced cardiovascular protection and pave the way for successful translation of exercise studies from bench to bedside in the prevention and treatment of cardiovascular diseases.
