Patients with type II diabetes are at high risk of developing cardiovascular diseases due to increased blood sugar, inflammation, insulin resistance, and physical inactivity. The effectiveness of exercises in improving cardiopulmonary fitness have not been well documented and practiced in Pakistan. The objective of this study is to determine the comparative effects of Periodized circuit and strength training in improving cardiovascular fitness, pulmonary functions , quality of life and glycemic control in type II diabetes patients. The study will be a randomized clinical trial. Based on the inclusion and exclusion criteria participants will be divided into 2 groups, Group A and Group B. The study will be 6 weeks, 3 sessions per week (18 sessions). Group A will be asked to perform Periodized circuit training 45 min per session (20 min aerobic exercise with 10 min warm up and cool down) with moderate intensity, 10min break and 15 min of resistance exercise while Group B will follow Conventional strength training 45 min per session, 35 min of strength and endurance training with 10 min of warm up and cool down. The study outcomes measures will be pulmonary functions (FEV1. FVC, FEV1/FVC ratio) through digital spirometer quality of life through health-related quality of life (HRQOL) questionnaire , cardiopulmonary fitness ( heart rate, blood pressure, oxygen saturation through 6MWT) and Glycemic control through (BCM). The data will be assessed at baseline, daily after the interventions and end of the study. Data will be analyzed using IBM SPSS software version 23.
