Kinesiology study: High-Intensity Workouts Help Diabetics

High Intensity but brief workouts appear to be able to reduce type 2 diabetics' blood sugar levels. That is the conclusion from a McMaster University study. The researchers discovered that the benefits could be attained in just two weeks and with six high intensity workout sessions. This is good news for diabetics who find it hard to keep to the recommended exercise routines suggested for them.
From the Department of Kinesiology at McMaster, Professor Martin Gibala who was the study's supervising author said: "These findings are intriguing because they suggest that exercising very strenuously for short periods of time, may provide many of the same health benefits as traditional exercise training," adding that "This is the first study to show that intense interval training may be a potent, time-efficient strategy to improve glycemic regulation in people with type 2 diabetes."
The 30 minutes sessions which took up a total of 75 minutes per week had the effect of lowering post meal blood sugar spikes, reducing 24-hour blood sugar concentrations and raising the mitochondrial capacity of skeletal muscle which is a sign of the body's metabolic health condition.
For the workouts the participants had to ride an exercise bike for 60 seconds, ten times and at 90% of their maximal heart rate. In between each flurry of exercise, the participants were allowed one minute recuperation. Including the warm up and cool down sections, the total time of each session was only 25 minutes.
This training schedule is beneficial for diabetics who are finding it hard to keep to the Canadian Diabetes Association's recommendation of 150 minutes of moderate to vigorous exercise per week
Commenting on the study as a whole, Gibala said, "The improved glycemic control may be linked to changes in the subjects' muscles, such as an improved ability to clear glucose from the blood after meals", adding that "We need to conduct further research to identify the mechanisms behind these results."
I really love what you do, bravo! Thank you very much for sharing with us this article.
