|Diabetes Mellitus, Type 2||Other: Aerobic Training Other: Progressive resistance training|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||Differential Effects of Aerobic Versus Progressive Resistance Training on Metabolic Profile and Fitness in Older Adults With Diabetes Mellitus - a Randomized Controlled Trial|
- Hemoglobin A, Glycosylated (Hba1c). Measuring unit: percentage [ Time Frame: 2 months ]Blood was drawn from each subject who fasted at least 10 hours overnight. Hba1c (%) was measured using high performance liquid chromatography (HPLC Variant II Bio Rad Laboratories, Munich, Germany). Change in Hba1c before and after intervention were looked at.
- Peak volume of oxygen consumed (VO2peak) or fitness level. Measuring unit: ml/kg/min [ Time Frame: 2 months ]Modified Bruce protocol on a treadmill using Cosmed K4B2 machine to measure
- Anthropometric measurements [ Time Frame: 2 months ]weight (kilogram), height (metres), body mass index (BMI), waist circumference (centimeters) and body fat (percentage). Measurements to be taken before and after intervention.
- Cholesterol [ Time Frame: 2 months ]Blood was drawn from each subject who fasted at least 10 hours overnight. Total cholesterol and triglycerides (TG) were measured using enzymatic colorimetric methods with cholesterol oxidase-peroxidase amino phenazone phenol and glycerol-3-phospahte oxidase-peroxidase amino phenazone phenol. High-density lipoprotein cholesterol (HDL-C) was measured using homogenous enzymatic colorimetric assay. Low-density lipoprotein cholesterol (LDL-C) was calculated using the Friedewald formula.

Active Comparator: Aerobic Training
50 minutes of aerobic training, 18 sessions within 2 months period
Other: Aerobic Training
18 sessions over 2 months period. Each session consist of 50 minutes of aerobic training at 65-70 % of maximum predicted heart rate
Experimental: Progressive Resistance Training
50 minutes of progressive resistance training consisting of nine resistance exercises, each conducted 3 sets of 10 repetitions. 18 sessions over 2 months period.
Other: Progressive resistance training
18 sessions completed in 2 months. each session consists of 50 minutes of resistance training which is made up of 3 sets of 10 repetitions of nine resistive exercises using machines and free weights at 65-70% of 1-repetitive maximum.
Many studies have shown the importance of aerobic training with respect to management of diabetes. However adoption of aerobic activities may be challenging for some individuals with diabetes, especially the elderly and the obese. There is increasing interest in resistance training and no study have looked at direct comparison between the two.
Subjects with diabetes but is generally sedentary (determined by means of a questionnaire) were recruited and randomized in one of the two groups. Subjects are supervised in a group and a completer is defined as one who completed 18 sessions within 8 weeks.
