简介：通过短跑和中长跑运动员在300W负荷时进行30s全速踏车试验,结果显示前15s的踏车速度与运动员的速度能力呈正相关,提示:300W负荷时进行30s全速踏车试验,可作为评定运动员速度能力的一种简易方法

简介：剧烈运动时,人体要通过深呼吸,为机体组织及器官的快速新陈代谢过程补充足够的氧气,研究深呼吸时人体肺内气体的流动及输运机理,对运动生理学及临床医学具有理论意义和临床价值.采用有限体积法数值,求解Navier-Stokes方程组,数值研究深呼吸情况下,人体三级支气管模型内的吸气流动规律,比较了均匀及抛物型速度进气条件对支气管内流动分布的影响.结果表明:深呼吸时,支气管内出现了复杂的流动现象,包括主流的射流-尾流结构及m-型结构,以及二次流的2涡向4涡结构演变过程,与平静及正常呼吸状态相比,深呼吸使肺内中部及侧部下游支气管内流量分流不均匀性加重,压力损失急剧增大,支气管内壁承受更大的气动负荷.
