Study summary

Type 2 diabetes (T2DM) is a metabolic disease characterized by chronic hyperglycemia that occurs as a result of any disorder in insulin secretion or insulin activity. Regular physical activity is important in preventing and managing this disease.

Read the detailed description

T2DM causes significant mortality and morbidity, increases healthcare costs, and increases the risk of cardiovascular disease. Due to the rapid increase in the number of individuals with diabetes, preventing and controlling this disease and living with diabetes is important. In patients with T2DM, pulmonary functions decrease in relation to glycemic control and disease duration. Decrease in cardiorespiratory fitness can lead to cardiovascular mortality. Cardiovascular mortality increases as exercise capacity decreases. Although the determinants of exercise intolerance in diabetes are not fully understood, a number of abnormalities in pulmonary diffusion capacity, maximum cardiac output, blood oxygen capacity and skeletal muscle properties cause exercise tolerance. Peripheral factors such as skeletal muscles also affect exercise intolerance. Insufficient oxygen use in skeletal muscles is considered one of the causes of exercise intolerance in T2DM patients. To reduce the cardiovascular mortality rate and risk factors associated with cardiovascular disease, physical activity level is important in T2DM patients, as in all populations. Maintaining physical activity level plays a protective role against both T2DM and cardiovascular disease. But traditional exercise training guides generally focus on walking exercises. Because exercises in this form are frequently used in daily life activities. It is known that upper extremity movements are frequently used in daily living activities, and aerobic exercise using the upper extremities is thought to be safe and effective in these patients due to diabetic foot complications. There is no study in the literature investigating the effects of upper extremity aerobic exercise training in T2DM.

The primary aim of the study is to investigate the effects of upper extremity aerobic exercise training applied to T2DM patients on exercise capacity, muscle oxygenation and physical activity level.

The secondary aim of the study is to investigate its effects on upper extremity functional exercise capacity, dual task performance, respiratory functions, respiratory muscle strength and endurance, peripheral muscle strength, shortness of breath, fatigue, depression, anxiety, sleep and quality of life.

Blood sugar measurement will be performed before exercise training. Individuals with a blood sugar result of \>300 mg/dL will not be allowed to exercise that day.

  • OtherControl Group

    Time frame: through study completion, an average of 2 year

  11. Dyspnea in daily life

    "Modified Medical Research Council" dyspnea scale will be used to question dyspnea perception during activities. This scale is a 5-point scale based on rating various physical activities that increase shortness of breath. The lowest and highest values on this scale are as follows: Level 0 "No shortness of breath except strenuous exercise" and level 4 "Too breathless to leave the house or breathless while dressing or undressing."
