For those who recurrently do cardio (like operating, swimming, dancing, and so on.), you could have in all probability seen that your blood sugar reacts in another way relying on the kind of cardio.
Whereas steady-state cardio will often make your blood sugar drop, interval coaching could make it improve.
The identical goes for resistance coaching (weight lifting) and blood sugar. Some varieties of resistance coaching will make your blood sugars improve!
On this submit, I’ll speak about how various kinds of resistance coaching have an effect on your blood sugar and the methods you’ll be able to attempt to proactively handle your blood sugar throughout and after resistance coaching.
At all times talk about modifications to your insulin doses together with your medical group. Since we’re all a bit of completely different, chances are you’ll want to regulate in another way for train than I do.
Why resistance coaching is sweet for individuals with diabetes
I completely love resistance coaching for 3 causes:
- Resistance coaching makes me really feel robust and empowered.
- Resistance coaching has helped me form my physique to my liking.
- Resistance coaching in the end makes my diabetes simpler to handle, because it improves my physique’s means to make the most of insulin.
Resistance coaching usually falls into two classes
- Low-rep (heavy) coaching with pauses between every set.
- Excessive-rep coaching or supersets with little relaxation between units. Your coronary heart price is elevated all through the exercise.
Every kind of resistance coaching will have an effect on my blood sugar a bit of in another way throughout my exercises however they each have the identical long-term advantage of a considerably improved insulin sensitivity.
How high-rep resistance exercises have an effect on my blood sugar
Usually, I have to be a bit of extra cautious and watch my sugars extra carefully if I do high-rep exercises, supersets, or a number of compound leg workouts (like squats, deadlifts, or lunges).
These sorts of exercises may have a cardio-like (cardio) impression on my blood sugar since my coronary heart price shall be elevated for many of the session and I can count on my blood sugar to drop.
I deal with periods like these virtually as I might deal with steady-state cardio – by lowering my pre-workout insulin dose by about 30%-50%.
How low-rep resistance exercises have an effect on my blood sugar
In the case of extra conventional resistance coaching with fewer reps (lower than about 12 reps per set), the scenario is a bit of completely different. When doing exercises like this, I typically see my blood sugar go up, and typically I don’t see a lot of an impression in any respect. It comes all the way down to what physique half I’m coaching.
For smaller muscle teams like arms and shoulders, my coronary heart price received’t often improve that a lot regardless of the heavy weights, and my blood sugar will stay steady. If I do heavy chest, again, or leg exercises, nonetheless, I’ll most probably see an impression on my blood sugar, and it may well typically be a rise. My physique reacts in the identical method as once I do an interval cardio exercise.
Given this information, I’ll scale back my pre-workout insulin dose minimally or in no way for a low-rep exercise, relying on the physique components I’m coaching.
The best way to put together for resistance coaching and stop post-workout lows
In the case of resistance coaching, pre-workout meals play an enormous function in whether or not you’ll achieve success within the health club. I at all times eat one thing earlier than and after a strength-training exercise to make sure I’ve sufficient vitality to do the exercise, rebuild my muscle tissue, and keep good blood sugar ranges.
My pre-workout snack is a reasonably low glycemic carb (like brown rice) and a few lean protein (like rooster breast) which I eat about an hour earlier than my exercise. By consuming a low glycemic carb and a few protein, I get sufficient vitality for my exercise with out having to take a number of insulin.
My post-workout snack consists of a low or high-glycemic carb with an simply digested protein (like fruit and a whey protein shake).
As talked about, I usually scale back my insulin dose for the pre- and post-workout meals by as much as 50%, particularly on high-rep and superset days, because of the cardiovascular (cardio) part of the exercise, which at all times makes my blood sugar drop.
Nonetheless, taking a little bit of insulin earlier than a resistance coaching exercise additionally has the profit that it reduces my threat of excessive blood sugar throughout the low-rep periods.
The best way to modify your insulin as much as 36 hours after a resistance exercise
My strategy to insulin changes for the 24 to 36 hours after I go away the health club is identical it doesn’t matter what form of resistance coaching I’ve completed.
What occurs once you do resistance coaching is that you simply create microscopic tears in your muscle fibers, and for the subsequent 24 to 36 hours, your muscle tissue heal and get larger and stronger. Throughout this era, your muscle tissue want vitality to heal and that has to return from someplace, so low blood sugars can simply be the end result if I don’t plan forward.
If I do resistance coaching lower than 4 occasions per week, I’ll usually have to scale back my nighttime basal insulin by as much as 50% on the times on which I work out (that is completely different for each particular person so it’s essential to experiment and observe your outcomes to seek out what works greatest for you).
If I do resistance coaching greater than 4 occasions per week, the elevated insulin sensitivity is current on a regular basis and I can merely decrease my nighttime basal completely with out having to regulate for particular person exercises.
Word: For those who do resistance work to the purpose of extreme or delayed soreness, you’ll be able to really improve insulin resistance. If the muscle tissue are being repaired for a number of days on account of excessive injury, you’ll be able to’t restore glycogen in them till the restore is finished, and that causes insulin resistance.
Abstract
I discover it simpler to regulate for resistance coaching than for cardio, so long as I’m very conscious of the form of resistance coaching I’m doing and bear in mind these tips:
- Excessive-rep exercises wherein your coronary heart price is elevated will most probably make your blood sugar drop.
- Low-rep exercises that don’t elevate your coronary heart price considerably (like arms or shoulders) most probably received’t have an effect on your blood sugar.
