The Effect of Use of Medical Masks on Exercise Capacity and Leg Endurance in Youth

Study Overview
=================
Brief Summary
-----------------
The use of masks has become an important part of life in outbreak conditions. In order to prevent the spread of the outbreak, many people in society may have to wear masks for hours during the day. As a mask type, the medical mask is frequently preferred in society. There are limited studies on how the use of medical masks affects the person wearing the mask while performing various activities that require different energy needs during the day. Therefore, this study aims to investigate how the use of medical mask affects exercise capacity and leg endurance with simple field tests.

Detailed Description
-----------------
Medical masks in use today are disposable and consist of three or four fine to very fine fibers. Medical masks are divided into three groups as type I, type II, and type IIR according to performance requirements. It is generally recommended for type I patients, type II, and type IIR healthcare professionals. The fact that many people in society use medical masks for hours in the current outbreak conditions and it is not known how long this situation will last suggests that the effects of the medical mask should be investigated further. This study was designed to investigate the effects use of a medical mask on exercise capacity and lower extremity endurance in young people. In the analysis using the G * Power 3.1.9.7 program, the sample size was calculated as 79 when the power ratio was at least 85% and the alpha error rate was 0.05. Participants included in the study will perform 3 field tests. Tests will be performed in the form of 30 seconds sit-to-stand test, incremental shuttle walk test (ISWT), and 6-minute walk test (6 MWT), respectively. Participants will come to the working place for 2 days to be evaluated. In this process, they will perform field tests one day with a medical mask and the other day without a mask. Whether the field tests to be performed on the first day will be with or without a medical mask will be decided through randomization. The tests to be made in the second visit will be carried out within 10 days with the time of the previous test, environmental conditions, and test sequence. The mask to be used in tests is a type I medical mask recommended for general public health in outbreak situations. The mask has three layers. During the study, the mask will be replaced with a new one at the end of each test. Also, mask-wearing comfort at rest, during daily living activities, and after ISWT will be evaluated with a 10-item scale. In the study, attention will be paid to precautions such as the researcher's use of a face shield and the protection of social distance in order to prevent the risk of contamination.

| Distance traveled in ISWT | It means the distance traveled in ISWT. Its unit is meters. | Until the second field tests are completed, up to 10 days | 
| 30 seconds sit to stand test result | The result is the total number of stands within 30 seconds. | Until the second field tests are completed, up to 10 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mask comfort level | It is the evaluation of each of the 10 sensations that can occur with the use of a mask with visual analog scale (VAS). | Until the second field tests are completed, up to 10 days | 
| Dyspnea VAS score | It will be evaluated using VAS. | Until the second field tests are completed, up to 10 days | 
| Dispnea modified borg scale (MBS) score | It will be evaluated MBS. | Until the second field tests are completed, up to 10 days | 
| Fatigue VAS score | It will be evaluated using VAS. | Until the second field tests are completed, up to 10 days | 
| Fatigue MBS score | It will be evaluated using MBS. | Until the second field tests are completed, up to 10 days |
