本文测定16例中老年长跑者肺活量、通气功能、弥散功能及呼吸动力机制指标,并以9例同年龄组不参加长跑看作对照。结果:肺活量、最大通气量及第一秒最大呼气率,长跑组较对照组有所提高,但经统计学处理无显著差别;CO弥散量及CO弥散系数,长跑组与对照组比较有非常显著差别;静态肺顺应性长跑组与对照组比较有非常显著差别。从弥散功能及肺顺应性改善的机制探讨,说明长跑有利于呼吸功能改善,有益于氧的吸收及利用,因而有助于老年人心肺功能的改善。
In this paper, 16 elderly middle-aged and long-term runners were measured lung capacity, ventilation, diffuse function and respiratory motility indicators, and 9 cases of the same age group did not participate in long-distance as a control. Results: The vital capacity, the maximum ventilation and the maximum expiratory rate in the first second were higher in the long-distance running group than those in the control group, but there was no significant difference by statistical analysis. The diffusivity of CO and the CO diffusion coefficient were significantly different between the long-distance running group and the control group Significant difference; static lung compliance long-run group compared with the control group has a very significant difference. From the diffusion function and lung compliance mechanism to improve, that long-distance run is conducive to improving respiratory function, beneficial to the absorption and utilization of oxygen, and thus contribute to the improvement of cardiopulmonary function in the elderly.
