: The inspiratory muscles play a fundamental role in cardiorespiratory performance, especially in water sports. The main objective of this study was to investigate the effects of an inspiratory muscle warm-up (IMW) protocol on the performance and respiratory parameters of scuba divers prior to performing two diving tests, one static and the other dynamic. : Eight young, active divers (six men and two women; 26.63 ± 4.67 years of age) volunteered for the study. In two sessions, one using an IMW protocol and the other without IMW, participants performed two underwater tests with a gas tank: a static immersion at the bottom of the pool for 5 min and a dynamic test consisting of swimming underwater for 12 min at 1 m/s. Some cardiorespiratory parameters such as gas expenditure, oxygen saturation (SO), heart rate (HR), spirometry, and rating of perceived exertion (RPE) were measured before and after each of the tests. : Significant differences were observed in gas expenditure using IMW in both static and dynamic testing ( < 0.05) and in RPE in dynamic testing ( < 0.05). HR values were significantly higher in the pre-dynamic test with IMW and the post-static test with IMW. Finally, with the use of IMW, spirometry values were significantly higher ( < 0.05) in static tests after immersion, whereas in the dynamic test, they were significantly higher before the immersion ( < 0.05). : Based on the results of this study, the use of the IMW prior to a dive would be recommended for better overall physical performance, oxygen expenditure, improved pulmonary function, and lower perceived exertion.
吸气肌在心肺功能表现中起着基础性作用，尤其是在水上运动中。本研究的主要目的是调查吸气肌热身（IMW）方案对水肺潜水员在进行两项潜水测试（一项静态测试和一项动态测试）之前的表现和呼吸参数的影响。
八名年轻、活跃的潜水员（六名男性和两名女性；年龄26.63±4.67岁）自愿参与本研究。在两个阶段中，一个阶段采用IMW方案，另一个阶段不采用IMW，参与者使用气瓶进行两项水下测试：在泳池底部进行5分钟的静态浸没，以及以1米/秒的速度在水下游泳12分钟的动态测试。在每次测试前后测量一些心肺参数，如气体消耗、血氧饱和度（SO）、心率（HR）、肺活量测定以及主观用力程度分级（RPE）。
在静态和动态测试中，使用IMW时的气体消耗均存在显著差异（<0.05），在动态测试中的RPE也存在显著差异（<0.05）。在动态测试前使用IMW以及静态测试后使用IMW时，HR值显著更高。最后，使用IMW时，浸没后静态测试中的肺活量测定值显著更高（<0.05），而在动态测试中，浸没前的肺活量测定值显著更高（<0.05）。
基于本研究结果，建议在潜水前使用IMW，以获得更好的整体身体表现、氧气消耗、改善肺功能并降低主观用力程度。
