Abstract
Objective: The aim of this study was to investigate the effects of physical activity (PA) at different levels of intensity on body composition and cardiometabolites among patients with type 2 diabetes mellitus (T2DM). Methods: Seventy patients with T2DM (female, 64.7%; age, 60.4 ± 7.9 years; body mass index, 25.6 ± 3.6 kgㆍm2; duration of diabetes, 12.5 ± 7.7 years; A1c, 7.8 ± 1.3%) were monitored their PA by using activity tracker (fitbit HR®:FB) for 7 days in free-living conditions. In this cross sectional study, patients were divided into an exercise group (EX, n = 58; subjects had been participating regular PA for at least 30 min/day, 3 days/week for 3 months) or a control group (CON, n = 21; patients did not participate in regular PA). We measured variables of body composition and cardiometabolic components in all patients. Results: There was no significant difference in sex, duration of diabetes and age between groups (P > 0.05). There was no significant difference in total energy expenditure (2203.7 ± 531.8 kcal vs. 2100.0 ± 442.9 kcal) and step counts (12518.6 ± 4695.6 kcal vs. 10731.6 ± 6784.6 kcal) between groups (P > 0.05). However, moderate-to-vigorous PA (68.1 ± 51.9 min vs. 38.6 ± 51.1 min, P = 0.037) and vigorous intensity PA (41.5 ± 36.0 min vs. 14.7 ± 18.2 min, P = 0.003) were greater in EX than those in CON. BMI (24.8 ± 3.2 kgㆍm2 vs. 26.6 ± 4.1 kgㆍm2, P = 0.046), fat mass (18.8 ± 6.3kg vs. 22.3 ± 8.3 kg, P = 0.047), and %fat (29.2 ± 7.0% vs. 33.2 ± 8.1%, P = 0.036) were lesser in EX than those in CON. Fasting glucose (155.8 ± 55.7mg/dL vs. 188.6 ± 68.0 mg/dL, P = 0.038) and total cholesterol (163.5 ± 35.2 mg/dL vs. 190.3 ± 34.8 mg/dL, P = 0.011) were lesser in EX than those in CON. Interestingly, light intensity PA was significantly correlated with BMI (r = -.392, P = 0.001), fat mass (r = -.484, P < 0.001), and % fat (r = -.525, P < 0.001). Moderate intensity PA was significantly correlated with A1c (r = -.251, P = 0.046) and glucose (r = -.289, P = 0.020). Vigorous intensity PA was significantly correlated with glucose (r = -.267, P = 0.033). Conclusion: Regular PA was effective in improving body composition and cardiometabolic components. Low level of PA shows benefit in improving body composition and moderate-to-vigorous intensity of PA has a benefit for reducing fasting glucose.
