The effect of physical activities of various intensities on the energy expenditure of type 2 diabetic men

Abstract

Interventions that focus on changing lifestyles through the combined use of dietary management, weight reduction, and increased physical activity are essential for managing type 2 diabetes mellitus (T2DM). The objective of the present study was to examine mildly obese T2DM patients [ n=10; mean age (+/-SD), 51.29+/-6.80 years; body mass index (BMI), 30.26+/-6.19 kg/m(2); and glycosylated haemoglobin (HbA(1c)), 8.16+/-1.16%)] and to compare them with normoglycaemic persons ( n=10; age, 53.00+/-9.48 years; BMI, 27.63+/-3.33 kg/m(2), and HbA(1c), 5.85+/-0.56%) in terms of energy expenditure while performing physical activities of various intensities (i. e. light, moderate, and heavy). The resting metabolic rate for T2DM patients was significantly higher than that for healthy controls (2200+/-354 kcal/day vs. 1628+/-176 kcal/day, respectively; p<0.0001). The values of energy expenditure at all three levels of physical activity were comparable between the two groups. Physical activity seems to have various beneficial effects on mildly obese T2DM patients because it increases the plasma glucose consumption, resulting in similar energy expenditure in comparison with normoglycaemic individuals.

Obese Japanese Adults with Type 2 Diabetes Have Higher Basal Metabolic Rates than Non-Diabetic Adults

“…Huang et al (28) reported that BMR in these patients was 8.4% higher in females and 4.6% higher in males than in the corresponding nondiabetic subjects. Maiolo et al (29) also reported that BMR was 35% higher in diabetic patients. It is important to note that BMR was not adjusted for body composition in these studies which may explain a large portion of the increase in BMR.…”

Energy Expenditure in People with Diabetes Mellitus: A Review

“…At speeds of walking range from 0.6 to 1.6 m/s, Petrovic et al (66) presented a general pattern of a higher cost of walking (express as milliliters per kilogram per minute) in diabetic patients with neuropathy (significant difference at all speed of walking) and in diabetic patients without neuropathy (significant difference at 1.4 and 1.6 m/s) in comparison with healthy subjects. However, Maiolo et al (71) found no significant difference in net EE of walking (at three different intensities) between patients with DM and healthy people.…”
