A structured yoga program designed to improve core stability, postura balance, and stress management. The traditional yoga sessions will focus on breathing control, static and dynamic postures, and progressive muscles engagements. Each session last 30 minutes it's supervised by a physiotherapist, and takes place in a quiet room to minimise external distractions.

Stress will be measured by the Depression, Anxiety, and Stress Scale (DASS-21) - Stress Subscale

The DASS-21 Stress Subscale evaluates the participants' perceived stress levels over the past week. It consists of seven items rated on a 4-point scale ranging from 0 ("Did not apply to me at all") to 3 ("Applied to me very much or most of the time"). The stress subscale focuses on symptoms such as difficulty relaxing, nervous tension, irritability, and feeling easily upset.

Total scores are calculated by summing the item scores and multiplying by two to obtain a standardized value. Higher scores indicate greater stress levels. This assessment was used to determine the changes in stress levels before and after the intervention.

Heart rate (beats per minute/bpm) will be measured to assess the physiological stress response. Measurements will be taken using a digital heart rate monitor while participants are seated comfortably. Each participant rested for five minutes prior to the measurement to ensure accuracy. The heart rate will be recorded three times at one-minute intervals, and the average of the three readings will be used for analysis. A decrease in post-intervention heart rate indicates improved relaxation and reduced physiological stress.

Systolic and Diastolic blood pressure (in mmHg) will be assessed to evaluate cardiovascular responses associated with stress and relaxation. Measurements will be taken using an automatic digital sphygmomanometer on the participant's dominant arm while seated. Participants rested for at least five minutes before the first reading. Three consecutive readings will be obtained, and the average of the systolic and diastolic values will be calculated for analysis. Lower post-intervention readings reflect improved cardiovascular regulation and reduced stress levels.

Core stability was assessed using the plank and side plank endurance tests, which measure the ability of trunk muscles to maintain a neutral spine position against gravity.

Plank test: Participants support their body on forearms and toes, maintaining a straight line from head to heels. The duration (second) that the position is held is recorded. The test will be repeated three times with rest intervals, and the mean duration will be used for analysis. Longer holding times indicate better core endurance and stabilization.
