Effect of Aerobic Training Versus Relaxation Techniques on Quality of Life in Patients With Post Covid-19 Irritable Bowel Syndrome

Sessions will be conducted 3 times per week. Each 40-minute session will include a 5-minute warm-up involving fast walking, slow running, and stretching, followed by an active phase of continuous running. The running period will start at 15 minutes and increase by 2 minutes every two sessions until reaching 30 minutes. The session will conclude with a 5-minute cool-down of slow running and stretching. Exercise intensity will be maintained at 13-15 on the Borg Rate of Perceived Exertion, with continuous walking performed on a treadmill.

Relaxation techniques will include slow deep breathing and mindfulness meditation exercises. The breathing exercise will involve six cycles per minute, with a 4-second inhalation and a 6-second exhalation, repeated for 30 minutes, three sessions per week. Mindfulness meditation will include a stress and pain management program with sessions starting at 10-15 minutes and gradually increasing to 20-30 minutes, three times per week. Sessions will be conducted in a quiet, comfortable space, focusing on breath awareness, body scanning, thought observation, and optional loving-kindness meditation, concluding with a reflection period.

All groups will follow a low-FODMAP diet (LFD). The LFD will exclude foods that commonly aggravate IBS symptoms, such as those containing lactose (dairy), fructose (e.g., apples, pears), and sweeteners like sorbitol and xylitol. Female participants with a BMI of 25 to 29 will aim for a daily calorie intake of 1,800 to 2,200 calories, adjusted based on age, activity level, and metabolism, to maintain weight while managing IBS symptoms effectively.
