: Systemic inflammation, attacks, deterioration of thoracic region mechanics, medications used, and decreased physical activity level (PAL) and fitness negatively may affect respiratory muscle strength. The primary aim of this study was to evaluate dynamic inspiratory muscle strength (S-index), PAL, and physical fitness in children with asthma compared to healthy peers. The secondary aim of this study was to investigate the relationships between S-index and peak inspiratory flow (PIF) values and functional parameters in childhood asthma. : This cross-sectional prospective study consisted of participants of 6-11 years of age, specifically, 20 children with asthma and 20 healthy peers. The device (POWERbreathe K5) evaluated PIF and S-index variables. PAL was determined with the Physical Activity Questionnaire-Child (PAQ-C) and fitness was evaluated with the FITNESSGRAM test battery. : The PIF Average (Avg): 1.8 ± 0.6, Best: 2.6 ± 0.6 (asthmatic children) vs. Avg: 2.4 ± 0.7, Best: 3.1 ± 0.9 (healthy children); = 0.017, = 0.027, respectively) and S-index (Avg: 34.1 ± 10.3, Best: 45.6 ± 9.9 (asthmatic children) vs. Avg: 43.2 ± 12.1, Best: 56.6 ± 14.7 (healthy children); = 0.015, = 0.008 respectively) values of children with asthma were significantly lower compared to healthy peers. The PAL and physical fitness of asthmatic and healthy peers were similar ( > 0.05). There were significant relationships between S-indexavg and S-indexbest with the PAQ-C score (r = 0.498, < 0.025 r = 0.547, < 0.013, respectively) and PIFavg and PIFbest with the PAQ-C score (r = 0.490, < 0.028 r = 0.602, < 0.005) in children with asthma. : Dynamic respiratory muscle strength is negatively affected in children with asthma whereas their physical activity and fitness levels are comparable to their peers. However, it was found that children with a higher S-index and PIF rate had higher PALs. These findings suggest that pulmonary rehabilitation interventions to improve respiratory muscle function should be considered an important strategy to maintain and increase physical activity levels in children with asthma.
全身炎症、发作、胸部区域力学的恶化、所使用的药物，以及身体活动水平（PAL）和健康状况的下降可能会对呼吸肌力量产生负面影响。本研究的主要目的是评估哮喘儿童与健康同龄人相比的动态吸气肌力量（S指数）、PAL和身体素质。本研究的次要目的是调查儿童哮喘中S指数与吸气峰流速（PIF）值及功能参数之间的关系。
这项横断面前瞻性研究由6至11岁的参与者组成，具体为20名哮喘儿童和20名健康同龄人。该设备（POWERbreathe K5）评估PIF和S指数变量。通过儿童身体活动问卷（PAQ-C）确定PAL，并使用FITNESSGRAM测试组合评估身体素质。
哮喘儿童的PIF平均值（Avg）：1.8±0.6，最佳值：2.6±0.6，而健康儿童的PIF平均值：2.4±0.7，最佳值：3.1±0.9（分别为P<0.017，P<0.027）；哮喘儿童的S指数（平均值：34.1±10.3，最佳值：45.6±9.9）与健康儿童的S指数（平均值：43.2±12.1，最佳值：56.6±14.7）相比（分别为P = 0.015，P = 0.008），哮喘儿童的值显著更低。哮喘儿童和健康同龄人的PAL和身体素质相似（P>0.05）。在哮喘儿童中，S指数平均值和最佳值与PAQ-C评分之间存在显著相关性（r = 0.498，P<0.025；r = 0.547，P<0.013），PIF平均值和最佳值与PAQ-C评分之间也存在显著相关性（r = 0.490，P<0.028；r = 0.602，P<0.005）。
哮喘儿童的动态呼吸肌力量受到负面影响，而他们的身体活动和健康水平与同龄人相当。然而，发现S指数和PIF率较高的儿童PAL也较高。这些发现表明，改善呼吸肌功能的肺康复干预措施应被视为维持和提高哮喘儿童身体活动水平的重要策略。
