摘  要:背景:离心收缩运动训练可能作为老年人维持生理功能及抗老化的有效方式之一,但目前有关抗老化文献却不清楚老年人进行离心收缩运动对抗老化或健康促进的真正效果。目的:综述离心训练延缓机体老化研究进展。方法:检索了1995至2018年Elsevier Science-direct、Medline、EM、中国知网、中国期刊全文数据库相关文献。检索关键词包括:离心收缩、向心收缩、等长收缩、增强式训练、离心收缩训练、老化、体适能、生理、血液生化等。共获得文献298篇,根据纳入和排除标准,共获得典型文献46篇进行分析讨论。结果与结论:①老年人进行离心收缩训练时会出现相对较低的有氧需求并产生较高的张力特性,其对肌力及肌肉质量的提升程度明显优于向心训练;②离心收缩训练能引发老年人肌肉的机械特性、肌肉型态改变及第Ⅰ类型单一肌纤维对钙离子的敏感度的提升;③离心收缩训练对提升老年人肌腱刚度、改善肌纤维收缩速度及增加骨质密度等有正向效益;④离心收缩训练易引发老年人肌肉细微损伤及延迟性肌肉酸痛症状,而熟悉离心收缩训练形态及负荷强度至关重要;⑤结果证实,离心收缩运动对于抗老化产生诸多正向效益,但目前老年人从事长期离心收缩训练的效果是否存在性别差异、是否更易引发肌肉损伤及酸痛风险、是否复合式离心训练比任何单独离心训练更有效、自觉舒服程度是否可作为老年人离心收缩训练强度控制的最佳方式等皆有待于更多的研究去证实。BACKGROUND:Centrifugal systolic exercise training may be an effective way to maintain physiological function and anti-aging in the elderly,but the true effect of centrifugal systolic exercise on anti-aging or health promotion in the elderly on anti-aging is unclear.OBJECTIVE:To summarize the research progress of centrifugal systolic exercise for delaying aging.METHODS:Elsevier Science-direct,Medline,EM,CNKI,and CJFD databases were retrieved for the articles published from 1995 to 2018.The key words were“centrifugal contraction,centripetal contraction,isometric contraction,enhanced training,centrifugal contraction training,aging,physical fitness,physiology,and blood biochemistry”.A total of 298 articles were obtained,and 46 eligible articles were included for analysis and discussion according to the inclusion and exclusion criteria.RESULTS AND CONCLUSION:The old people show low aerobic requirement and high tension during centrifugal contraction,and the improvement of muscle strength and muscle quality is better than centripetal training.Centrifugal contraction training can induce changes in mechanical properties and muscle morphology of the elderly and increase the sensitivity of type I single muscle fibers to Ca2+.Centrifugal contraction training has positive effects on enhancing tendon stiffness,improving muscle fiber contraction speed and increasing bone density in the elderly.Centrifugal contraction training is easy to cause minor muscle damage and delayed muscle ache symptoms in the elderly,and familiarity with centrifugal contraction training form and load intensity is essential.Centrifugal contraction exercise has many positive effects on anti-aging,but whether there are differences in the effect of long-term centrifugal contraction training in the elderly,whether it is more likely to cause muscle injury and pain risk,whether compound centrifugal training is more effective and more comfortable than any single centrifugal trainings,whether conscious comfort level can be used as the best way to control th
