Insulin dose reductions improve glucose control during exercise
Last updated September 4, 2026
Key finding
Blood glucose declined by 4.0 ± 2.8 mmol/L during exercise.
This study examined the effects of reduced doses of ultra-rapid-acting insulin aspart (URA-IAsp) and rapid-acting insulin aspart (IAsp) during moderate-intensity exercise, finding similar glucose-lowering effects across different doses.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This study examined the effects of reduced doses of ultra-rapid-acting insulin aspart (URA-IAsp) and rapid-acting insulin aspart (IAsp) during moderate-intensity exercise, finding similar glucose-lowering effects across different doses.
Clinical relevance
These findings are significant for individuals with diabetes who engage in physical activity, as they suggest that insulin dose adjustments can maintain effective glucose control during exercise. This could help prevent hypoglycemia and improve overall diabetes management.
Keep in mind
Unclear effectiveness due to lack of significant findings. Limited generalizability to broader populations. Sample size and participant characteristics not specified.

Main Effects
Blood glucose declined by −4.0 ± 2.8 mmol/L with 50% URA-IAsp, similar to other conditions (p > 0.05).
Blood glucose reduction was comparable with 75% URA-IAsp, showing no significant differences (p > 0.05).
50% dose of IAsp also resulted in similar glucose reductions (p > 0.05).
75% dose of IAsp showed comparable effects on blood glucose levels (p > 0.05).

Evidence Suggest
- Blood glucose levels decreased by −4.0 mmol/L with 50% URA-IAsp.
- No significant differences in glucose reduction across all insulin conditions.
- Study supports insulin dose adjustments during exercise for glucose control.
Who this applies to
- Individuals with diabetes engaging in moderate-intensity exercise.
- Patients requiring insulin therapy for blood glucose management.
Keep in Mind
- Results may not apply to all types of diabetes or exercise intensities.
- Further studies needed to confirm findings in larger, diverse populations.
- Effectiveness of insulin adjustments may vary based on individual responses.
Between the Lines
- Unclear effectiveness due to lack of significant findings.
- Limited generalizability to broader populations.
- Sample size and participant characteristics not specified.
