Summary

The primary aim of this study is to compare the respiratory function, respiratory muscle strength, functional capacity, and lower extremity strength of children with asthma and healthy children in the same age group. The secondary aim of our study is to determine the determinants of functional capacity in children with asthma.

Conditions

• Asthma in Children

Interventions

Type	Name	Description
OTHER	6-minute walk test	Functional capacity will be assessed with the 6-minute walk test (6MWT). 6MWT will be performed in accordance with the criteria of the American Thoracic Society. The 6MWT distance will be recorded in meters.
OTHER	Pulmonary function test	Pulmonary function test will be performed with a spirometer ("COSMED Pony FX" (COSMED; Italy) by ATS/ERS criteria. Forced expiratory volume in 1 second (FEV1) and peak expiratory volume (PEF) parameters will be measured. The results will be recorded both as a percentage of measured values and expected values.
OTHER	Respiratory muscle strength test	Respiratory muscle strength will be measured in accordance with ATS/ERS criteria using an electronic, mobile, (MicroRPM, Micro Medical; UK) intraoral pressure measuring device. Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) values will be recorded. Three measurements will be repeated for each maneuver and the highest value recorded as cmH2O.
OTHER	Lower extremity muscle strength test	The 30-Second Chair Test is administered using a folding chair without arms, with a seat height of 17 inches (43.2 cm). The chair, with rubber tips on the legs, is placed against a wall to prevent it from moving. The participant is seated in the middle of the chair, back straight; feet approximately a shoulder width apart, and placed on the floor at an angle slightly back from the knees, with one foot slightly in front of the other to help maintain balance. Arms are crossed at the wrists and held against the chest. The participant is encouraged to complete as many full stands as possible within 30 seconds. The participant is instructed to fully sit between each stand.
