Background and Aims

Exercising using high intensity interval training (HIIT) may help in improving glycemic control in diabetes. Although high workload volume HIIT may have increased health benefits, an adequate workload progression should be programmed when initiating HIIT. Our objective was to examine the effect on home capillary blood glucose monitoring (HCGM) of an exercise program of increasing volume in people with type 1 diabetes.

Methods

Exercising using high intensity interval training (HIIT) may help in improving glycemic control in diabetes. Although high workload volume HIIT may have increased health benefits, an adequate workload progression should be programmed when initiating HIIT. Our objective was to examine the effect on HCGM of an exercise program of increasing volume in people with type 1 diabetes.

Results

For all periods, there was a reduction of 1-h post-exercise HCGM compared with basal values before beginning each session. In addition, from the first period (one exercise series) through the third period (three series), a sudden drop of HCGM was observed between beginning and end of sessions but less between immediately and 1-h post-exercise.

Conclusions

Increasing progressively exercise workload volume with HIIT over 12 weeks decreased slightly and progressively HBGM just after exercise but not 1-h post-exercise in people with type 1 diabetes.
