Six men and six women (24.4 ± 6.4 years) who had been diagnosed with T1D for 7.3 ± 6.8 years volunteered for the study. Three RT sessions were repeated with the same experimental approach with randomized load percentages. Blood glucose measurements were performed at rest, after warm-up, immediately after the last set of each exercise, and 10, 20, and 30 minutes after the exercise session. Significant decreases from rest for blood glucose concentration in each intensity vs. post warm-up, immediately post exercise session, and 10, 20 and 30 minutes after total training session were observed. Effect size (ES) results for the 60 and 80% of 1RM intensities demonstrated large magnitudes. The three intensities investigated promoted a reduction in blood glucose levels and therefore can be recommended for diabetic patients. In addition, the moderate and high intensities appear to lower blood glucose levels to a greater extent than the low intensity.
