Managing blood sugars throughout and after train is likely one of the trickiest conditions to sort out as an individual dwelling with insulin-dependent diabetes.
On this submit, I wish to current an method to managing blood sugars throughout and after train, and present you your choices when doing it utilizing an insulin pump.
Let’s dive in…
This submit was written in collaboration with Tandem Diabetes Care as a part of their sponsorship of the Wholesome With Diabetes Problem.
There are two important levers to drag relating to managing blood sugars throughout and after train:
1) Carbohydrate consumption and
2) Insulin changes
For those who have interaction in leisure train a couple of instances every week for lower than an hour at a time, I like to recommend that you just attempt to alter your insulin moderately than add extra carbs previous to train (except after all you’re hungry or have already got low blood sugar).
Insulin changes
Lately, some very sensible folks sat down and reviewed the scientific knowledge on Type 1 diabetes and train, wrote up the findings, and printed; “Train administration in sort 1 diabetes: a consensus assertion” within the Might concern of The Lancet.
The explanation I’m so enthusiastic about this paper is that it jives with my very own findings of easy methods to efficiently alter my insulin to handle my blood sugars throughout and after train. It’s nice to lastly have a scientific consensus to again that up.
The paper within the Lancet discusses blood sugar administration and train for a number of day by day injections and pump remedy, so whereas this submit focuses on pump changes demonstrated on a Tandem pump (so you possibly can see how it might truly work), you’ll find extra particulars within the precise paper which is free to obtain on the Lancet.
Though these are scientific suggestions, it’s nonetheless HIGHLY advisable that you just talk about any adjustments to your insulin routine together with your medical group.
The important thing physiological learnings
If you’re dwelling with insulin-dependent diabetes, the important thing physiological learnings from the consensus assertion are how several types of train almost certainly will have an effect on blood sugars. This isn’t totally different from what I’ve been writing about for years, however to recap:
- Cardio train with fixed depth (like strolling or operating) tends to lower blood sugar ranges
- Anaerobic train with depth various between rigorous and relaxation (like resistance coaching or interval coaching) tends to extend blood sugars
- Combined sorts of train (cardio and anaerobic combine) may give a combined blood sugar response
- Train can enhance the chance of hypoglycemia for 24-48 hours after train
This data is crucial as a result of it may assist decide the suitable carbohydrate or insulin adjustment technique to stop blood sugars out of vary throughout and after train. Nevertheless, please notice that how a lot your blood sugar might be affected is particular person so you’ll want to study your distinctive response to totally different sorts of train.
You may learn extra about how to do that in my “How one can discover your method” submit.
The rules beneath are meant as a place to begin that may HAVE to be individualized, optimally in collaboration together with your medical group.
Situations for insulin changes and advisable actions
The consensus assertion outlines 4 totally different eventualities for train and insulin changes. I’ll undergo them one after the other earlier than displaying you easy methods to truly alter your pump settings.
- Insulin changes for fasting cardio actions longer than 30 min
For those who do fasted cardio train, the consensus assertion recommends a basal insulin discount of 50-80% as much as 90 minutes earlier than beginning your train or full suspension of insulin supply for a most of 60 minutes. Resume regular basal whenever you cease exercising
- Insulin changes for fueled cardio train of various intensities:
Comply with identical basal suggestions as with fasting cardio exercise plus think about lowering your mealtime bolus.
The desk beneath properly depicts the advisable pre-workout bolus methods if in case you have consumed carbohydrates over the past 90 minutes earlier than your exercise.
| Train length | Bolus discount | |
| 30 min | 60 min | |
| Gentle cardio train | -25% | -50% |
| Reasonable cardio train | -50% | -75% |
| Heavy cardio train | -75% | NA |
| Intense cardio or anaerobic train | None | NA |
Instance: When you have a meal with carbohydrates earlier than your exercise and plan to do reasonable cardio train for half-hour, you would scale back your bolus for that meal by 50%.
- Insulin changes for anaerobic train:
Since your blood sugar will are likely to rise throughout anaerobic train, a unique technique for staying in vary is required. Though there isn’t any dosing suggestion for such a train, it’s advised {that a} basal price enhance may also help deal with or stop hyperglycemia (excessive blood sugars) throughout and after train.
One of many causes for this enhance in blood sugar is that the livers launch of glucose can surpass the rise in your insulin sensitivity throughout anaerobic train.
Personally, I eat a small meal and bolus earlier than a resistance coaching or interval exercise to counteract any enhance in blood sugars.
- Insulin adjustment after exercises:
For those who take pleasure in a meal inside 90 minutes of finishing your train, you would possibly wish to think about lowering your bolus ~50% for that meal to stop hypoglycemia.
When utilizing an insulin pump, you possibly can make the most of the choice of lowering your basal post-workout to cut back the chance of hypoglycemia within the 24-48 hours after exercises the place your insulin sensitivity is roaring.
The paper is especially centered on easy methods to cut back nighttime hypoglycemia after exercises and recommends lowering your basal insulin in a single day by 20% or eat a bedtime snack with out insulin.
