Results: Obese people with diabetes have several barriers to exercise such as fear of injury, lack of time, energy, resources, motivation, skill, and social influence.
To evaluate the efficacy of 12 weeks graded and balanced exercise intervention within a multidisciplinary program for weight management in reducing exercise barriers, and improving exercise capacity and diabetes control.
106 subjects with mean age (54±10 ys), diabetes duration (10±9.5 ys), weight (241.7±42.1 lbs), BMI (38.5±5.4 kg/m2), A1c (7.5±1.3%), waist (46.9±5.6 inches) were enrolled in a multidisciplinary weight management program that included a structured dietary intervention and behavioral and educational support. The exercise intervention included cross, interval, circuit, and superset training that progressed gradually from 20 minutes, 4 days/week to 60 minutes 6 days/week under the supervision of an exercise physiologist. Diabetes medications were adjusted as needed throughout the program. Subjects underwent a 6-minute Walk Test and completed the Barriers to Being Active Questionnaire before and after the intervention.
Mean weight loss was 24.4±11.4 lbs (p<0.001), waist decreased by 3.8±2.2 inches (p <0.001) and A1c reduced to 6.6±0.99% (p<0.001). At baseline, walking capacity was 488±80 meters, 1 min recovery heart rate (HR) was 91±16 bpm, and 3 min recovery HR was 85±14 bpm. They improved significantly (p<0.0001) by 41±38.7 meters, 6±12 bpm and 5±10 bpm respectively. Baseline score of barriers included: time 3±2.4, social influence 1.7±1.6, energy 3.2±1.9, motivation 4.5±2.5, injury 1.2±1.9, skill 0.5±1.8, resources 0.7±1.4, and a total score of 17.2±9. Barriers scores reduced significantly (p<0.0001) by: time 1.4±2.3, social influence 1.4±1.9, energy 1.6±2.1, motivation 3.0±2.6, skill 0.7±1.2, and the total score by 8.5±7.0. Injury score reduced by 0.6±1.5 (p<0.01).
12 weeks of graded and balanced exercise intervention within a multidisciplinary weight loss program reduces exercise barriers and improves exercise capacity while reducing body weight and improving diabetes control in obese individuals with diabetes.
