Conditions

Prediabetes / Type 2 Diabetes

Keywords

exercise, anti-inflammatory markers, aerobic capacity

Brief summary

The aim of this study was to determine the effects of two different exercise protocols on body composition, aerobic capacity, blood lipid profile, some biomarkers, quality of life and exercise beliefs in participants at risk of diabetes.

Detailed description

After being informed about the study and possible risks, all participants who gave written informed consent and met the eligibility requirements will be randomly assigned to 2 separate groups.

Interventions

OTHERHigh Intensity Interval Training (HIIT)

1 minute interval, 1 minute active recovery 5 minutes warm-up - 3 minutes cool-down will be done at 60% of peak heart rate. Weeks 1-2: Loading at an intensity of 85% of peak heart rate, active recovery at an intensity of 60% of peak heart rate 4x1 Weeks 2-7: Loading at an intensity of 90% of peak heart rate, active recovery at an intensity of 60% of peak heart rate 6x1 Weeks 8-12: Loading at an intensity of 90% of peak heart rate, active recovery at an intensity of 60% of peak heart rate 8x1

5 minutes warm-up - 3 minutes cool-down will be done at 60% of peak heart rate. Weeks 1-2: Loading at 65% of peak heart rate intensity (22 minute) Weeks 2-7: Loading at 75% of peak heart rate intensity (30 minute) Weeks 8-12: Loading at 75% of peak heart rate intensity (38 minute)

Design outcomes

Primary

MeasureTime frameDescription
HbAc12 weeksIt is the amount of glycosylated hemoglobin in the blood.

Secondary

MeasureTime frameDescription
HDL12 weeksIt is the amount of high-density lipoprotein in the blood.
LDL level LDL12 weeksIt is the amount of low-density lipoprotein in the blood.
CRP12 weeksC-reactive protein is a protein produced in the liver.
Total cholesterol12 weeksCholesterol is a lipid that is necessary for the construction of cell membranes in the body and the production of some hormones and vitamin D.
Triglyceride12 weeksIt is a type of fat molecule found in the bloodstream and is used as the body's energy source.
Irisin12 weeksIrisin, defined as a myokine, is the proteolytic product of fibronectin type III domain 5 protein.
Adiponectin12 weeksAdiponectin is a protein hormone and adipokine, which is involved in regulating glucose levels and fatty acid breakdown.
IL-612 weeksInterleukin-6 is an endogenous chemical involved in inflammation and B cell maturation.
Resistin12 weeksResistin is a hormone secreted from fat cells.
Kemerin12 weeksIt is a protein that is involved in many metabolic events such as adipogenesis, angiogenesis and glucose homeostasis, including the chemoattractant function of the belt.
Osteocalcin12 weeksOsteocalcin is a bone-specific protein found in osteoblasts.
Leptin12 weeksLeptin is a hormone that acts on the hypothalamus through negative feedback secreted from fat cells, suppressing food intake and increasing energy expenditure.
TNF-alpha12 weeksTumor necrosis factor alpha is a chemical messenger produced by the immune system that initiates inflammation.
Cardiometabolic risk level12 weeksCardiometabolic risk has been defined as a cluster of metabolic and cardiovascular abnormalities, including abdominal obesity, insulin resistance, hypertension, dyslipidemia, and atherosclerosis, that predispose individuals to cardiovascular disease and type 2 diabetes.
Body composition12 weeksBody composition describes the amount of fat, bone, water and muscle in the body.
Aerobic capacity12 weeksAerobic capacity is the capacity of large striated muscle groups to adapt to work using energy obtained from aerobic metabolism.
Exercise Health Belief Model Scale12 weeksExercise Health Belief Model Scale is a 5-point Likert-type scale consists of 32 items.The scale consists of 5 factors and there is no reverse item. The highest and lowest score on the scale is 160 and 32, respectively. Higher scores indicate higher level of exercise health belief.
Short Form-36 Questionnaire12 weeksThe Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. SF-36 measures eight scales: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health.Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. High scores indicate good health status.
