Aim

The aim of this study was to evaluate the effects of interval high intensity inspiratory muscle training (IMT) on resting breathing pattern in patients with advanced lung disease.

Methods

IMT was performed daily and training load set at 50 % of the maximal inspiratory pressure. Participants were evaluated at pre-IMT, post 8 weeks of IMT and follow-up (3 months after the end of IMT). Breathing pattern (volume and time variables as well as percentages of contribution to tidal volume) was evaluated by Optoelectronic Plethysmography at rest. Friedman test was used to verify the differences between the three time-points (p < 0.05).

Results

Nineteen patients (54 ± 16 years old; 5 males) were evaluated at pre-IMT and post-IMT and fourteen were assessed at follow-up. There was no significant difference (p > 0.05) in any comparison for all evaluated breathing pattern variables at the three time-points.

Conclusion

Resting breathing pattern was not significantly changed after 8 weeks of IMT in patients with advanced lung disease.

吸气肌训练对晚期肺病患者静息呼吸模式的影响

目的

本研究的目的是评估间歇高强度吸气肌训练 (IMT) 对晚期肺病患者静息呼吸模式的影响。

方法

IMT 每天进行，训练负荷设置为最大吸气压力的 50%。在 IMT 前、IMT 8 周后和随访（IMT 结束后 3 个月）时对参与者进行评估。呼吸模式（体积和时间变量以及对潮气量的贡献百分比）在休息时通过光电体积描记法进行评估。弗里德曼检验用于验证三个时间点之间的差异（p < 0.05）。

结果

19 名患者（54 ± 16 岁；5 名男性）在 IMT 前和 IMT 后接受评估，14 名患者在随访时接受评估。在三个时间点的所有评估呼吸模式变量的任何比较中都没有显着差异（p > 0.05）。

结论

晚期肺病患者在接受 IMT 8 周后静息呼吸模式没有显着改变。
