Fasting glucose, insulin, glycated hemoglobin (HbA1c), total cholesterol, triglycerides, free fatty acids (NEFA) levels, and HomeOstasis Model Assessment for estimating insulin resistance (HOMA-IR) values in differently trained subjects. Fasting glucose, insulin, HbA1c, total cholesterol, triglycerides, NEFA levels, and HOMA-IR values were evaluated in elite (E), subelite (SE), recreational (R), and sedentary (S) subjects. ; .
