Effect of an Eight-week High-intensity Interval Training Program on Serum Cardiac Troponin I Level of Streptozotocin-induced Diabetic Rats

Background One of the complications of diabetes, as a chronic metabolic disorder, is cardiovascular diseases. Objective This study aims to investigate the effect of an eight-week High-Intensity Interval Training (HIIT) program on serum Cardiac troponin I (CtnI) level in streptozotocin-induced diabetic rats. Methods In this experimental clinical trial, 30 rats were randomly assigned into three groups of healthy Control (C), Diabetic (D), and diabetic+training (D+T). The third group performed the training which included a treadmill running at an intensity of 85%-90% of maximum speed in 6-12 sessions of 2 min for 8 weeks, 5 days per week. Blood glucose level and high-sensitive CtnI levels were measured 48 hours after the last training session and 12 hours of fasting. One-way ANOVA and Tukey’s test were used to analyze the collected data, considering a significance level of P
