Determination of the Validity of One-Minute Sit-to-Stand Test in Obese and Overweight Children and Adolescents

Study Overview
=================
Brief Summary
-----------------
Obese individuals need to be evaluated comprehensively before exercise programs are determined. Determination of exercise intolerance is important for the detection of functional limitations. One minute sit to stand test (1MSTST) can be used as an alternative to cardiopulmonary exercise tests (CPET) or field tests. It is easy to use, quick to apply, valid and reliable, and applicable even in small areas. In addition, it is a simple assessment adequate for children's needs and behaviors and can be easily applied both in the clinic and at home, making it easier to use in children. Studies have shown that 1MSTST is a valid test in chronic obstructive pulmonary disease (COPD), cystic fibrosis, interstitial lung disease, and, healthy children and adolescents. However, no study has been found regarding the validity of its use in obese children and adolescents.The aim of our study is to investigate the validity and reliability of 1MSTST in overweight-obese children and adolescents.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 1 min sit to stand test | Only a chair and a stopwatch are needed to apply the test. It is recommended to use a chair with a height of 45-48 cm, preferably against the wall, fixed, without arm support. The patients will sit with their feet flat on the ground and cross their arms over the chest. The patient will be asked to get up from the chair and sit down as fast as he/she can for 1 minute. The number of standing up will be recorded. | Baseline | 
| 6 minute walk test | The patient's exercise capacity will be determined by the six minute walk test. The test will be applied in a corridor 30 meters long. The patient will be asked to walk as fast as possible for six minutes. The patient can stop during the test if they needed. The total time, the number of times it has stopped and the total distance traveled will be recorded. Oxygen saturation, heart rate, and blood pressure measurements will be taken before and after the test. According to the modified Borg scale, dyspnea, leg fatigue and general fatigue will be questioned. | Baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Waist circumference | Waist circumference will be measured using a tape measure from the midpoint between the lowest rib and the iliac crest, when the patient is standing . | Baseline | 
| Hip circumference | Hip circumference will be measured parallel to the ground with a tape measure at the level of the trochanter major. | Baseline | 
| Body fat percentage | Body fat percentage will be analyzed with the BIA instrument (Tanita MC 780 MA Body Composition Analysis, Amsterdam, Netherlands). | Baseline | 
| Body muscle percentage | Body muscle percentage will be analyzed with the BIA instrument (Tanita MC 780 MA Body Composition Analysis, Amsterdam, Netherlands). | Baseline |
