Brief summary

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. Key words: CT (Circuit training), CF (Cardiovascular fitness), PF (Pulmonary function), CST (Conventional strength training), CVD (cardiovascular disease), T2D (Type 2 diabetes), BCM (Blood Glucose Monitor)

Interventions

OTHERGroup A: Periodized Circuit Training

Group A: Periodized Circuit Training Protocol The participants in this group performed Periodized circuit training 45 min per session, 10 min break. Before start exercises patients performed 5 min warm up session then 20 min of aerobic exercise and 15 min of resistance exercise. The exercise session were, Walking, jogging, body weight, scissor exercise and lastly cool down session of 5 minutes

OTHERGroup B: Strength and Endurance Exercise Training Protocol

The participants in this group performed Conventional strength training 45 min per session, 10 min break. Before start exercises patients performed 5 min warm up session then 30 min of strength and endurance training. The exercise session were jogging or walking, Glute Bridge, prone back extension, and ankle planter flexion and lastly cool down session of 5 min.

Design outcomes

Primary

MeasureTime frameDescription
Cardiovascular Fitness6 weeksA 6-minute walk distance (6-MWD) in meters were performed to determine the cardiovascular fitness pre-post exercise
Pulmonary Functions6 weeksDigital Spirometer is a common tool used to test pulmonary functions through measuring the volume of air a person can inhale and exhale, as well as how quickly they can do so. It helps in diagnosing and monitoring respiratory diseases, and other conditions that affect lung function. The reliability is usually good with test results reproducibility generally being above 90%. The validity is also well-defined since spirometry is rated as gold standard of measuring the lung functioning. FEV1, FVC, and FEV1/FVC ratio were measured pre-post exercise through digital spirometer
HRQoL6 weeksHRQoL questionnaire were used to access quality of life of diabetes II patients pre-post exercise
Glycemic Control6 weeksBlood glucose monitor device were used to check the glucose level, pre-post exercise
