Dynamic Respiratory Muscle Strength and Endurance in Childhood Asthma

Peak inspiratory flow (PIF) may be due to respiratory muscle strength, especially in those with severe airflow obstruction. PIF appears to be lower in children and adolescents with asthma than in non-asthmatics and correlates positively with age, height, weight, and respiratory muscle strength. Although physical activity and fitness are also believed to be important in lung health, the relationship between lung function and physical fitness is unclear. It measures dynamic lung volumes, s-index and PIF and provides information on dynamic lung function in children and adolescents. In this study, the dynamic components of the lung will be compared between asthmatic and healthy children, and the relationship between respiratory parameters and physical assessment, such as physical fitness, activity and functional capacity, will be investigated in children with asthma.
