Brief summary
The aim of our study was to investigate the relationship between aerobic capacity, which will be revealed by aerobic exercise test, and HRV, blood pressure, heart rate and pulmonary function parameters in healthy children interested in different sports branches (boxing, weightlifting, taekwando, swimming). The main questions it aims to answer are: * Is there any relationship between aerobic capacity demonstrated by 20 m shuttle test and heart rate variability, blood pressure, heart rate and respiratory parameters in different sports branches? * Is there a relationship between the month/year that children/adolescents are involved in sports and HRV, blood pressure and respiratory parameters? Participants: * Before the exercise test, ECG, blood pressure, heart rate and pulmonary function test will be performed. * A 20 meter shuttle run test will be performed. * Measurements will be repeated after the exercise test.
Interventions
OTHER20 meter shuttle run test
20 Meter Shuttle Run Test: Subjects run distance of 20 meters round trip. Running speed is monitored at certain intervals with help of a tape recorder that gives a signal. Subjects start running when they hear first beep and must reach other line(one foot must cross the line) by second beep. When they hear second signal, they return to starting line. The speed, which is slow at beginning, gradually increases every 10 seconds. The subject adjusts his/her pace so that he/she is on the other line at the second signal. If subject misses one signal and catches second signal, test continues. If subject misses two signals in row and doesn't reach line at other signal, test is terminated. At end of test, aerobic power values are calculated from VO2max estimation table in ml/kg/min according to number of sit-ups run. At end of test, marks obtained by athlete are calculated and VO2max value of subject is calculated in ml/kg/min from evaluation table.

| FVC | 1 hours | A portable spirometer device will be used for the measurement of pulmonary function. During the test, the child will be placed in an upright sitting position with the pelvis in the most neutral position. Before the test, the child will be trained, demonstrated and explained what to do during the test. A different mouthpiece will be used for each child. The nose will be closed with the help of a clothespin and the measurement will be repeated 3 times and the best result will be taken into consideration. During the test, first inhale and exhale into the spirometer mouthpiece at normal tidal volume. Then a deep breath is taken and a rapid deep exhalation is requested. The exhalation period should last at least 6 s without interruption. |

| SDNN (msn) | 1 hours | HRV obtained by electrocardiography (ECG) recording is a method that provides information about sympatho-vagal balance, calculated on the basis of the variability of the intervals between heart beats. Recordings will be taken in a quiet and calm room in the supine position. A 3-way bipolar limb lead with remote bluetooth connection (poly-spectrum-8/ex) will be used for ECG recording. Electrodes will be appropriately attached to the wrists and ankles. Participants will be asked to remove any metal objects (coins, belts, watches, bracelets, phones, etc.) that may interfere with the ECG. Participants will be pre-informed not to move, talk, breathe normally and remain in a supine position during the recording. After 5 minutes of ECG recordings are taken, data on HRV parameters will be obtained with device-specific software. |

| Systolic blood pressure | 1 hours | Care will be taken to ensure that the person being measured is not cold, not in pain, not anxious, and not urinating or having a large bowel movement before the measurement. After the brachial artery is felt by hand, the cuff will be placed 2-3 cm above the antecubital fossa so that it is not too loose or tight. Care will be taken to ensure that the skin is not pinched, the palms are open and facing upwards. They will be warned not to make a fist. The cuff will be placed in the middle of the arm at the level of the heart so that the arm and heart are in the same horizontal plane. Blood pressure measurement is started with an automatic measuring device (F.Bosch, Germany). The device inflates the cuff enough to stop arterial blood flow. As the cuff deflates, it measures oscillations in the blood flow and then calculates the blood pressure using device-specific algorithms. The device also provides the heart rate in beats per minute. |
