Brief summary
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.
Detailed description
Asthma prevalence is high in childhood and adolescence and the disease imposes an economic burden. In studies, patients with peak inspiratory flow (PIF) showed variability in severe obstruction and a dependence on respiratory muscle strength. PIF appears to be lower in children and adolescents with asthma than in those without asthma and correlates positively with age, height, weight and respiratory muscle strength. Also, although physical activity and fitness are believed to be important in lung health, the relationship between lung function and physical fitness is unclear. Physical activity improves exercise capacity and outcomes in patients with asthma or chronic obstructive pulmonary disease, but there is insufficient evidence that it improves lung function. Physical fitness in childhood and adolescence has been associated with increases in lung volumes throughout early adulthood. These relationships may weaken with age and may not be significant in older age groups. s-Index (a special calculation) and PIF describe dynamic lung volumes. There are very few studies in the literature that dynamically evaluate respiratory muscles and functions compared to their healthy counterparts and interpret these tests together with physical evaluations. In addition, reference values for the s-index and PIF in children with asthma are uncertain due to the small number of studies. The results of this study will contribute to future studies in determining the test reference values.The investigators think that the results of the study will contribute to future studies in determining the test reference values.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dynamic Respiratory Muscle Strength and Endurance | Day 1 | POWERbreathe K-Series, K5, intelligent digital breathing trainers, The first 2 breaths should be taken as quickly and deeply as possible. During these breaths, the maximum respiratory capacity is measured. The index of the power indicator ranges from 10 to 240 cm H2O. Higher values are better. For hygiene reasons, the test is done with a disposable mouthpiece. |
| Pulmonary Function Test | Day 1 | It is evaluated with the Pulmonary Function Test. After a deep, full inspiration, a forced expiratory maneuver is performed. Used with disposable antiviral filter. The patient's height and body weight are measured and recorded with age. It is done 3 times, there should be no more than 10% difference between the values. The highest value is accepted. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| FITNESSGRAM (a) Sit and lie down test with back support: | Day 1 | FITNESSGRAM is a physical fitness test with its own guide. There are cut-off values according to age and gender. (a) Sit and lie down test with back support: While sitting, the person extends his foot and bends the other lower extremity. The hands are stretched forward four times in a row and the fourth distance is recorded. |
| FITNESSGRAM (b) Trunk Extension-extension test: | Day 1 | (b) Trunk Extension-extension test: The person lies face down with the hands under the thighs. He lifts his body twice, looking at a coin. In the second, the distance between the chin and the cushion is recorded. |
| 6 Minutes Walking Test | Day 1 | Six munite walk test It will be measured with the 6 Minute Walk Test. You can walk for 6 minutes at a fast pace without running in the 30 m long corridor. The six minute walk test will be measured by the 6 Minute Walk Test. You can walk at a fast pace for 6 minutes without running in a 30 m long corridor. The distance walked is recorded in meters. |
| FITNESSGRAM (d) Push-up test: | Day1 | (d) Push-up test: The person is face down and the hands are shoulder-width apart. The chest moves up and down, with the elbows locked and unlocked (every three seconds) without bending the body. The number of repetitions is noted. |
| FITNESSGRAM (e) PACER test | Day 1 | (PACER test): The PACER test is a progressive aerobic cardiovascular endurance run. It is done on a 20-meter course. He jogs at an accelerating rhythm (decreasing by half a second every minute). The test ends if the rhythm is missed or the line is not reached before two beeps. The number of laps is recorded. |
| FITNESSGRAM (c) Trunk Flexion flexion test: | Day 1 | (c) Trunk Flexion flexion test: The person lies on his back with the knees bent and touches the fixed band on the sides at hand level with the fingertips. Lifts the trunk in a repeat rhythm (every three seconds). It does not move from the lane while rubbing its hands. The number of repetitions performed correctly in accordance with the rhythm is noted. |
| Physical Activity Questionnaire | Day 1 | It is a 5-point liket questionnaire consisting of 10 questions created to determine the physical activity level of children for the last 1 week. |
