What this study is about

Obesity has been defined by the World Health Organization (WHO) as an abnormal accumulation of fat in the body that negatively affects health and has been reported to be the most significant public health problem of the 21st century. In the late 1990s, WHO described obesity as a "global epidemic." This epidemic and its associated complications cause the death of 2.8 million adults annually. Additionally, obesity imposes a significant financial burden on countries' healthcare and social security systems. Therefore, obesity stands out as an issue that requires urgent preventive measures. Obesity is associated with various abnormalities in respiratory functions. Changes in respiratory system mechanics due to decreased lung volumes indicate a strong link between obesity and chronic respiratory diseases. Furthermore, obesity is a risk factor for conditions such as hypertension, cardiovascular diseases, and diabetes. Yoga is known to have numerous positive effects on health and can provide significant benefits, particularly in improving respiratory functions. Yoga is also an important tool for coping with stress, which can positively influence the respiratory system. It has been reported that yoga reduces the impact of stress on respiratory rate, promoting deep breathing and relaxation. Some studies on the effects of yoga on obesity have not reached significant conclusions. A study comparing the effects of Vinyasa and Hatha yoga on obesity management found that neither type had a significant effect on metabolism. These studies fail to fully explain the mechanism by which yoga affects obesity due to differences in yoga styles and their lack of standardization, variations in practice durations, and the differing characteristics of study populations. Furthermore, studies on obesity and yoga often have short intervention durations (an average of 8 weeks), with most involving 60-90 minute sessions conducted 1-2 times per week. Since longer-term studies are needed to better understand the relationship between obesity and yoga, this study aims to investigate the effects of yoga exercises on body composition, respiratory parameters, functional level, sleep quality, quality of life, and emotional state in overweight and obese women.

yoga exercises

Behavioral

The yoga program, based on Hatha yoga content, will be conducted in groups of 10 participants, for 12 weeks, 3 days a week, at the same time each day (12:00-13:00), and will be administered by an experienced physiotherapist (Appendix 4). Before starting the training program, the exercise group will be given a one-week adaptation period, during which the exercises to be performed in three sessions per week will be taught. Participants in the exercise group who miss sessions for various reasons will be given an additional one-week period to make up for missed sessions. Participants who miss more than four sessions will be excluded from the study. Participants were informed in advance about any personal items they might need before each yoga session (such as towels, tissues, etc.) and were advised to bring their own. The yoga sessions were held in the sports hall of the Artvin Çoruh Dormitory, where the required equipment for yoga (e.g., mats, blocks) was provided. The yoga program was

Primary outcomes

Forced Vital Capacity (FVC)From enrollment to the end of treatment at twelve weeks

Spirometry is a fundamental test for assessing lung function and is essential for the evaluation and monitoring of respiratory diseases. Spirometry is a physiological test that measures the maximum effort a person can exhale and the maximum volume of air they can exhale. For the evaluation of lung function, a Care Fusion brand spirometry device will be used. Before the test, the patient's gender, age, height, and weight will be recorded in the device. The patient will be seated in a position that facilitates the required maneuvers, and nasal breathing will be prevented by placing a nose clip. After three test measurements with 95% consistency, the best value obtained will be used.

Assessment of Dynamic Balance and Functional Level (Timed Up and Go Test)From enrollment to the end of treatment at twelve weeks"

The test, originally called the "Timed Up \& Go Test," is frequently used to measure the functional status of the lower extremities. This test also assesses individuals' ability to maintain balance during transfers and walking. In this test, individuals are asked to sit on a standard fourtyfive cm high chair with their feet flat on the ground, then stand up, walk as quickly but safely as possible for three meters, turn around at the marked point three meters away, walk back toward the chair, and sit down again. The time taken between starting and finishing the test is recorded in seconds using a stopwatch. Individuals are asked to repeat the test three times, and the average of the three trials is used for analysis.

Body Mass IndexFrom enrollment to the end of treatment at twelve weeks

Weight (kg): The Tanita BIA scale device will measure the individual's body weight in kilograms. This measurement is essential for calculating other body composition parameters and assessing overall health. Height (cm): A stadiometer with an accuracy of ±0.5 cm will be used to measure the individual's height in centimeters. Accurate height measurement is fundamental for calculating body mass index (BMI) and assessing growth patterns.After completing the measurements, the dietitian will calculate the BMI by dividing weight in kilograms by the square of height in meters. BMI is a widely used indicator to assess whether an individual has a healthy body weight for a given height.

Waist CircumferenceFrom enrollment to the end of treatment at twelve weeks

Waist circumference will be measured at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest, using a non-stretch tape measure. The individual will stand with feet close together, arms at the sides, and body weight evenly distributed. The measurement will be taken at the end of a normal expiration, ensuring the tape is horizontal and snug but not compressing the skin.

Hip CircumferenceFrom enrollment to the end of treatment at twelve weeks

Hip circumference will be measured around the widest portion of the buttocks, with the tape parallel to the floor. The individual will stand with feet close together, arms at the sides, and body weight evenly distributed. The measurement will be taken to the nearest 0.1 cm, ensuring the tape is snug but not compressing the skin.

Forced Expiratory Volume at One Second (FEV1)From enrollment to the end of treatment at twelve weeks

Spirometry is a fundamental test for assessing lung function and is essential for the evaluation and monitoring of respiratory diseases. Spirometry is a physiological test that measures the maximum effort a person can exhale and the maximum volume of air they can exhale. For the evaluation of lung function, a Care Fusion brand spirometry device will be used. Before the test, the patient's gender, age, height, and weight will be recorded in the device. The patient will be seated in a position that facilitates the required maneuvers, and nasal breathing will be prevented by placing a nose clip. After three test measurements with 95% consistency, the best value obtained will be used.

Peak Expiratory Flow (PEF)From enrollment to the end of treatment at twelve weeks

Spirometry is a fundamental test for assessing lung function and is essential for the evaluation and monitoring of respiratory diseases. Spirometry is a physiological test that measures the maximum effort a person can exhale and the maximum volume of air they can exhale. For the evaluation of lung function, a Care Fusion brand spirometry device will be used. Before the test, the patient's gender, age, height, and weight will be recorded in the device. The patient will be seated in a position that facilitates the required maneuvers, and nasal breathing will be prevented by placing a nose clip. After three test measurements with 95% consistency, the best value obtained will be used.

Maximum Mid-expiratory Flow 25-75% (MMEF25-75)From enrollment to the end of treatment at twelve weeks
