摘要

目的:在运动过程中,呼吸肌在呼吸和躯干稳定中起双重作用。呼吸肌功能与躯干稳定性之间的关系尚未明确。这项研究的目的是检查呼吸肌肉功能对健康年轻人躯干肌肉耐力的影响。方法:采用McGill躯干肌肉耐力试验,包括躯干屈曲耐力试验(FE)、Sorensen试验(ST)和侧桥试验(SB),对受试者的躯干肌肉耐力进行评价。通过使用口内压力计装置测量口内最大吸气和呼气压力来评估呼吸肌力量。呼吸肌耐力试验采用增量阈值负荷方案,使用阈值IMT装置。结果:共51例健康青年,平均年龄21.8±3.2岁。线性回归模型的结果显著解释了46%的SB变异和38%的FE变异(其中SB Adj R2=0.46, F=21.40, p< 0.001; FE Adj R2=0.38, F=15.65, p< 0.001)。呼吸肌耐力对躯干屈肌耐力的贡献为30%,而呼吸肌力量的贡献仅为8%。同样,呼吸肌耐力对躯干外侧屈肌耐力的贡献为38%,而呼吸肌力量的贡献仅为8%。结论:虽然呼吸肌力量和呼吸肌耐力是躯干肌肉耐力的独立影响因素,但在健康青年中,呼吸肌耐力对躯干肌肉耐力的影响大于呼吸肌力量。

The effects of respiratory muscle functions on trunk muscle endurance in healthy young adults
Purpose: Respiratory muscles play a dual role in breathing and trunk stability during activities. The relationship between respiratory muscle functions and trunk stability has not yet been clarified. The aim of the study was to examine the effects of respiratory muscle functions on trunk muscle endurance in healthy young adults. Methods: McGill's trunk muscle endurance tests, which consist of trunk flexion endurance test (FE), Sorensen test (ST) and Side Bridge test (SB), were used to evaluate the participants' trunk muscle endurance. Respiratory muscle strength was evaluated by measuring intraoral maximal inspiratory and expiratory pressures using an intraoral pressure meter device. The respiratory muscle endurance test was performed with the incremental threshold load protocol using a threshold IMT device. Results: A total of 51 healthy young adults, with a mean age of 21.8 ± 3.2 years, were evaluated. The results of the linear regression models were significantly explained 46% of the variance in the SB and 38% in the FE, (for SB Adj R2=0.46, F=21.40, p< 0.001 and for FE Adj R2=0.38, F=15.65, p< 0.001). Respiratory muscle endurance contributed 30% to the endurance of the trunk flexor muscles, while respiratory muscle strength contributed only 8%. Similarly, respiratory muscle endurance contributed 38% to the endurance of the trunk lateral flexor muscles, while respiratory muscle strength contributed only 8%. Conclusion: Although respiratory muscle strength and respiratory muscle endurance were independent contributors to trunk muscle endurance, respiratory muscle endurance more affected trunk muscle endurance than respiratory muscle strength in healthy young adults.
