Yoga and Aerobic Exercise Training in Primary Dysmenorrhea

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to compare the effects of aerobic exercise and yoga exercises on menstrual pain parameters (pain severity and duration, analgesic usage), uterine artery blood flow, menstrual stress level, physical fitness, anxiety/depressive symptom level, quality of life and sleep quality in individuals with primary dysmenorrhea. This study is a prospective, parallel group, randomized study. Three days a week for eight weeks, the participants in this study will receive individualized yoga and aerobic exercise. In the literature, there are no studies comparing the effectiveness of aerobic exercise and yoga in the management of PD, which is a public health problem that seriously affects women's lives. Especially when aerobic exercise and yoga exercises are considered, there is no study on how much the features such as uterine artery blood flow and physical fitness sub-parameters have changed with these two commonly used exercise types separately in the management of PD.

Detailed Description
-----------------
The aim of this study is to compare the effects of aerobic exercise and yoga exercises on menstrual pain parameters (pain severity and duration, analgesic usage), uterine artery blood flow, menstrual stress level, physical fitness, anxiety/depressive symptom level, quality of life and sleep quality in individuals with primary dysmenorrhea. This study is a prospective, parallel group, randomized study. It was planned to enroll 44 individuals with Primary Dysmenorrhea in this randomized study. A physical therapist is responsible for all assessments. Participants were included in one of two treatment groups (G1: Aerobic exercise; G2: Yoga exercise). In the literature, there are no studies comparing the effectiveness of aerobic exercise and yoga in the management of PD, which is a public health problem that seriously affects women's lives. Especially when aerobic exercise and yoga exercises are considered, there is no study on how much the features such as uterine artery blood flow and physical fitness sub-parameters have changed with these two commonly used exercise types separately in the management of PD. The results of our study show that norm values can be established by evaluating uterine arterial blood flow and physical fitness, instead of focusing on pharmacological treatment and classical nonpharmacological approaches (warm application, transcutaneous electrical nerve stimulation (TENS), acupuncture, etc.) in individuals with PD. It is aimed to develop new exercise protocols that can be done easily. It is expected that our results, which we will obtain in the light of the original values of our research, will contribute to the literature and guide future studies.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Menstrual pain severity | As primary outcome measures, the highest menstrual pain severity perceived by the participants in their last menstruation and the average of the pain severity in the first 3 days of their menstruation will be evaluated. A 10-cm VAS from zero (no pain at all) to 10 (the worst pain I have ever felt) will be used to determine the severity of menstrual pain. Individuals will be asked to mark the severity of pain they felt in the first 3 days of their last menstruation on 3 separate VAS lines. | Change in severity of menstrual pain from baseline up to end of 8th week, 3rd month, and 6th month. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Uterine artery blood flow | Determination of uterine artery blood flow changes will be made with Doppler US imaging device.

| Cardiovascular fitness | Cardiovascular fitness will be evaluated with the 6-minute walk test. For this test, which evaluates functional performance; Marking will be made at both starting points of a distance of 30 meters in the corridor. Individuals will be asked to walk for 6 minutes at the highest speed without running, and at the end of 6 minutes, the distance they walked will be recorded in meters. During the exercise test, vital signs such as blood pressure, heart rate, fatigue, shortness of breath, oxygen saturation of all individuals will be recorded before and immediately after the test. | Change in cardiovascular fitness from baseline up to end of 8th week, 3rd month, and 6th month. | 
| Muscular static endurance | For the abdominal static endurance test, a board will be used to position the patient in 60º flexion. The subjects will be positioned with the trunk at 60°, the hips and knees flexed at 90°, and the hands on the opposite shoulders, leaning against the board. The board will be pulled back 10 cm and the patient will be asked to keep his isometric position as much as possible by contracting his abdominal muscles. As soon as the subject's body touches the board, the test will be terminated and the time to hold the position will be recorded in seconds. The test is continued for a maximum of 120 seconds and after 120 seconds the test will be stopped. | Change in muscular static endurance from baseline up to end of 8th week, 3rd month, and 6th month. | 
| Muscular dynamic endurance | 30 seconds sit-up test will be used for dynamic endurance. In the 30-second sit-up test, individuals will be asked to stand up to the level of the lower angle of the scapula and return to the starting position, with the knees flexed at 90 degrees, the hands on the back of the neck and the soles of the feet on the ground, with the command to start in the supine position to evaluate the dynamic endurance of the abdominal muscles. The exact and correct number of starts during 30 seconds will be recorded as the test score. | Change in muscular dynamic endurance from baseline up to end of 8th week, 3rd month, and 6th month. | 
| Muscle strength (for lower extremity) | Dominant side knee extension strength for the lower extremity will be measured with the Nicholas Manual Muscle Tester. | Change in muscular strength from baseline up to end of 8th week, 3rd month, and 6th month. |
