MANGIAMARCHI, Pedro et al. Effects of high-intensity interval training and nutritional education in patients with type 2 diabetes. Rev. méd. Chile [online]. 2017, vol.145, n.7, pp.845-853. ISSN 0034-9887.


High-intensity interval training (HIIT) improves cardiometabolic markers, but its effects on the quality of life of patients with type 2 diabetes (T2D) is not well known.


To determine the effects of a 12-week HIIT exercise program on cardiometabolic and quality of life variables of T2D patients.

Material and Methods:

Nine T2D women were assigned to a HIIT + nutritional education (GE) and 10, to a nutritional education alone group (GC). At baseline and after each intervention, anthropometric and body composition parameters using bio-impedance were assessed, and a blood sample was obtained to measure serum lipid levels, blood glucose and glycated hemoglobin. Quality of life was assessed using the SF-12 questionnaire adapted for the Chilean population.


There were no significant changes on the lipid profile variables in the GE group, although HDL cholesterol was increased significantly (p < 0.05) in the GC group. Total fat mass was decreased in the GE group from 43.5 ± 1.5 to 41.9 ± 1.5%, p < 0.01. Fasting glucose and glycated hemoglobin decreased in the GE group. There was a significant correlation between the decrease in total fat mass and that of glycated hemoglobin. There were significant increases in quality of life parameters; physical function, physical role, pain, general health, vitality, emotional role, mental health, and social function in the GE but not in the GC group.


A 12-week program of HIIT plus nutritional education improves cardiometabolic and quality of life parameters on type 2 diabetics.
