Effects of postprandial exercise on blood glucose levels in adults with type 1 diabetes: a review
Study context
- Population
- Adults with T1D exercising postprandially (within 2 h after a meal)20 articles
- Comparison
- Postprandial exercise modalities: WALK, CONT MOD, CONT HIGH, IHE, HIIT
- Outcome
- Blood glucose change and hypoglycaemia occurrence during and after exercise
- Follow-up
- Acute (during exercise), subacute (≤2 h after) and late (>2 h to ≤24 h after exercise)
Methodological detailsliterature screened until November 2022, organised by exercise modality
- Literature screened until November 2022
- Organised by exercise modality
Pooled result
As reported in the abstract
Blood glucose change during exercise · acute (during exercise)
- All exercise modalities caused consistent acute glycaemic declines, largest effect size for CONT HIGH and smallest for HIIT, depending on duration and intensity
- Pre-exercise mealtime insulin reductions created higher starting blood glucose, protecting against hypoglycaemia, despite similar declines during activity between insulin reduction strategies
Further pooled results
- Research on the optimal timing of postprandial exercise is inconclusive
Safety
Nocturnal hypoglycaemia · late
- Nocturnal hypoglycaemia occurred after higher intensity postprandial exercise; risk could be diminished by a post-exercise snack with concomitant bolus insulin reduction
