Abstract:

Energy expenditure is affected due to mechanical and metabolic deficiencies in individuals with type 2 diabetes. The aim of this study was to evaluate the relationship between energy expenditure during the assessment of functional exercise capacity and type 2 diabetes parameters. Seventeen patients with type 2 diabetes were included in the study. Laboratory and anthropometric values were recorded. Functional capacity was assessed using a six minute walk test. Energy expenditure was assessed using the physiological cost index and six minutes walk test work. The physiological cost index was calculated by the difference between resting heart rate and heart rate at the end of the six-minute walk test (beats), divided by average speed (m/min). The six-minute walk work was calculated using six-minute walk distance (m) x body weight (kg). The average physiological cost index was 0.37 ± 0.18 (beats/m). The physiological cost index was associated with height, body mass index, fasting blood glucose and total cholesterol (p <0.05). Six minutes walking work was related to age, height, c-reactive protein, waist-hip ratio, fat percentage, lean body mass (p <0.05). Energy expenditure during functional capacity in patients with type 2 diabetes is associated with clinical parameters. It is recommended to examine both the physiological cost index and the six-minute walking test which is an alternative method of energy expenditure because of their relationship to different clinical markers.
