A comparison of cardiorespiratory fitness parameters TYPE 2 diabetic, prediabetic and healty individuals

Type 2 diabetes impairs cardiorespiratory fitness. Individuals with impaired glucose tolerance have an increased risk of type 2 diabetes and cardiovascular disease. There are no studies comparing cardiorespiratory fitness parameters of type 2 diabetic, prediabetic and healthy individuals in the literature. The purpose of this study was to compare cardiorespiratory fitness parameters of type 2 diabetic, prediabetic and healthy individuals. Thirteen diabetic, thirteen prediabetic, thirteen healthy subjects with same age and gender were enrolled in the study. Demographic, physical characteristics and laboratory findings of subjects were recorded. Body composition (Bioelectrical impedance analysis-BIA), lung function (pulmonary function test-PFT), respiratory muscle strength (maximal inspiratory and expiratory pressure/MIP-MEP), functional capacities (6 Minute Walk Test/ 6MWT), maximal exercise capacities (Incremental shuttle walk test/ISWT), cardiorespiratory fitness (Cardiopulmonary exercise test/CPET), physical activity levels (International Physical Activity Questionnaire/IPAQ; accelerometer), quality of life (Short Form-36) and activities of daily living (Canadian Activity Performance Measurement/COPM) were evaluated. Pulmonary functions, inflammatory levels, cardiorespiratory fitness levels, weekly physical activity levels, quality of life, activities of daily living, maximal exercise capacity, body composition and functional capacity of three groups were different (p <0.05). Type 2 diabetic and prediabetic individuals have decreased oxygen consumption. Type 2 diabetic patients' oxygen consumption is significantly lower than healthy subjects. Respiratory muscle strength and IPAQ scores of three groups were similar (p> 0.05). We suggest that it will be important to assess cardiorespiratory fitness in individuals with impaired glucose metabolism. Improving cardiorespiratory fitness according to CPET results could prevent or delay diabetic complications.
