PCOS also causes psychological disorders which include depression, anxiety, poor body image, low self-esteem and decreased health- related quality of life. Some well-controlled randomized clinical studies have been conducted to evaluate the effects of exercise training program in women with PCOS. There are many beneficial effects of exercises which improve physical fitness, body composition, and cardiovascular, hormonal, reproductive and psychological outcomes. Periodization training program involves period of active rest which allows muscle adaptations through variable intensity, volume and rest. The advantage of periodization is that it prevent from overtraining symptoms such as muscle stiffness, muscle soreness, sprain, strain, possible injury and decreased performance. High intensity interval training is effective in reducing body mass index and improving body composition in females with PCOS.

The study will be a randomized clinical trial and will be conducted in Mohsin memorial hospital Faisalabad. This study will be completed in time duration of ten months after the approval of synopsis and convenient sampling technique will be used. Total twenty four subjects will be assigned randomly by using lottery method into two groups. Group A will receive periodized resistance training and Group B will receive high intensity interval training. Warm up and cool down period of ten minutes of treadmill training will be performed by both groups. Data will be collected from all participants at baseline and after 8 weeks of treatment by using BMI and WHO-QOL BREF questionnaire. After assessing the normality data will be analyzed by using parametric or non-parametric test by using SPSS-25.
