Acute Effects of Different Intensities of Resistance Training on Glycemic Fluctuations in Patients With Type 1 Diabetes Mellitus

Abstract

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.

Glucose Variations and Activity Are Strongly Coupled in Sleep and Wake in Young Adults With Type 1 Diabetes

“…However, these findings do suggest that the relationship between glucose and physical activity is likely both bidirectional and operating on multiple time scales, especially during wakefulness. This proposition is not surprising because during the daytime many factors, including caloric intake (Neu et al, 2015); aerobic and resistance exercise (Davey et al, 2013; McMahon et al, 2007; Silveira et al, 2014; Sonnenberg, Kemmer, & Berger, 1990); and work, school, and family demands impact daytime glucose control in people with T1DM.…”

Routine daily physical activity and glucose variations are strongly coupled in adults with T1DM

“…; Silveira et al. ). Furthermore, the relationship between glucose and activity likely differs between sleep and wake.…”

“…In this instance, we would expect to see a rise in glucose prior to a rise in the activity level. Conversely, changes in activity also can precipitate changes in glucose; high levels of activity may elicit an increase in insulin sensitivity driving glucose levels lower (Yardley et al 2013;Silveira et al 2014). Furthermore, the relationship between glucose and activity likely differs between sleep and wake.…”

Exercise and Beta-Glucan Consumption (Saccharomyces cerevisiae) Improve the Metabolic Profile and Reduce the Atherogenic Index in Type 2 Diabetic Rats (HFD/STZ)

“…The effects of physical exercise on the improvement of glycemic control in diabetic patients (decrease in HbA1c and fasting glucose) are frequently reported [32,33,34]. Generally, this effect is due to the increased glucose uptake by skeletal muscle during exercise and increased insulin sensitivity for some hours after physical activity [35].…”
