I Ma Working Out Again So Why Is My Blood Surgar Going Higher

Have you ever wondered why your blood sugar falls during certain types of exercise whilst increasing during and types of practise? Or why you sometimes become loftier blood sugars after exercise?

If you lot're curious nearly the scientific explanation of how exercise tin can raise blood sugar, read on.

I rarely come across scientific studies that explore how exercise affects blood saccharide in people living with type 1 diabetes, so when I recently got my hands on just such a research paper, I dug in with great involvement (they specified blazon i diabetes, merely I would remember that the results are applicable to anybody using insulin).

Well actually, Google and I dug in. This research paper is heavy reading. You know those scientific papers where you feel similar yous need an advanced degree (plus a whole lot of Googling) only to empathise the introduction? This is one of them.

The paper is titled "Effect of intermittent high-intensity compared with continuous moderate exercise on glucose production and utilization in individuals with blazon 1 diabetes", and is written by a team of scientists from Australia. It was published in the American Journal of Physiology – Endocrinology and Metabolism in 2007 (non exactly new research, but peer-reviewed research nonetheless, which means it'southward legit).

I thought that the field of study was relevant and interesting enough to spend the time reading and understanding it. Then, since I've done the heavy reading, let me share what I've learned with y'all.

Exercise and blood sugar impact

And so why do some types of exercise make our claret sugar drib similar crazy while others get in increase or inappreciably have whatsoever affect? I know from my own experience that I really have to watch my blood sugars if I do steady state cardio, while an interval training session will have little impact or even make my blood sugars go upwards.

It turns out that the main reason why interval training won't make your sugars driblet as much as steady state cardio comes down to two factors.

1. Increase in glucose production
2. Glucose utilization

Both of these factors are affected by exercise, regardless of the type of exercise you do. However, the scientists found that after 15 minutes, in that location was a statistically pregnant difference in the two factors depending on whether the test subjects did interval training or steady state cardio.

They institute an overall college production of glucose, both during and upwardly to ii hours post-exercise in the test subjects that did interval training when compared to those doing steady country cardio. Glucose utilization was also higher for the interval grooming grouping, but information technology never caught upwardly with the glucose production.

This ways that interval training has less of an impact on blood sugars (despite the interval training grouping putting in more than overall work) than steady state cardiovascular training because your body is producing glucose as fast or faster than y'all can use information technology.

The scientists don't know exactly why nosotros see the greater increase in glucose production for interval training, but they theorized that it might be due to musculus glucagon breakdown.

Another finding was that cortisol (the stress hormone) didn't increment more than with interval training. That's a really positive finding since increased cortisol isn't something we generally strive for due to the many negative side effects such as weight gain, impaired immune function, and gastrointestinal problems.

How to implement the research findings

Bated from me finding this super fascinating, what can nosotros do with this information?

I recollect that this is a great piece of knowledge to accept for trained athletes, those who are just starting out, and for parents managing their child's diabetes. It tin can serve equally a guide when determining the amount of insulin and carbohydrates to safely administer prior to and postal service an activity.

The scientists compared interval training to sports like basketball and soccer where y'all have intense bursts of action. I would add newer sports such as CrossFit, HIIT (loftier-intensity interval training) and HIT (loftier-intensity preparation). Information technology could also exist boot camps, spinning classes, or if you just exercise a lot of cardiovascular interval training and heavy resistance training.

Armed with this scientific knowledge (and a lot of experience), I know that I don't need to reduce my insulin as much before and after an interval preparation or a resistance training session (I may even need a niggling actress insulin(!)), while I will need to make reductions if I practise 40-lx minutes of steady land cardio.

For me, steady state cardio tin can be a long walk, a bike ride, or walking on an incline, Stairmaster or elliptical. With all of these activities, I'll see an well-nigh instant driblet in blood sugars. However, the improved glucose utilization wears off pretty speedily later on I stop exercising, so I know to lower my insulin prior to steady state cardio but not after.

To summarize:

1. Exercise impacts BOTH glucose product and utilization
2. When doing interval grooming, increased glucose product outpaces your increased glucose utilization
3. When doing steady land cardio, glucose utilization dominates production
4. Because of this, your claret carbohydrate may rise during and after high-intensity interval practise, while it most likely volition drop during steady country cardio

I hope this mail service answered the question "does exercise increment blood sugar?" If y'all desire to acquire more nigh managing your blood carbohydrate during exercise, please read my article "How to Manage Your Blood Sugars When Exercising with Diabetes".
