本研究测试了两种训练方法的影响,一个个性化的气体交换阈值对应的心率(得到),另一相对应的心率的50%最大心率储备,最大的轻快和高频的心肺反应在24慢性气道患者限制(CAL)。病人被随机分配到个性化的培训集团(它;n = 12)或标准化培训集团(圣;n = 12)。4周的培训计划由静止的自行车运动,5 days.week-1。整理之前,基于心率的目标水平组之间没有明显不同(109 + / - 4和110 + / - 3次。最低为1,和圣,分别)。岗位培训,显著增加symptom-limited耗氧量(V 'O2.sl)和最大氧气脉冲被发现,而圣表现出无显著变化。每组,有统计学增加一样V 'O2, sl,增加(p < 0.01)高于圣(p < 0.05)。然而,展出相伴而逐步降低每分通气量(V本部),二氧化碳生产(V 'CO2)和静脉乳酸浓度((La)),而圣了组与组之间这些参数无显著变化(p < 0.01)。呼吸模式也改变后,在相同的代谢水平和在同一组与组之间通风水平(p < 0.05)。 Cardiac responses were modified in the two groups. At the same metabolic level, a significantly lower cardiac frequency was found both for IT and ST (intragroup p < 0.05 after training). In contrast, the increase in O2 pulse was only significantly higher in It after training. These data show the greater efficiency of an individualized training protocol based on determination of gas exchange threshold as compared to a standardized protocol, in improving exercise performance, when applied to a patient group. Despite an apparently similar target training level, the individualized method clearly optimized the physiological training effects in patients with chronic airway limitation and, more particularly, decreased their ventilatory requirement.
