Do you know how your body deals with sugar????
We are in the final days of testing after our 8 week trx training research study wohoo!! Today is our second last day of oral glucose tolerance testing (OGTT) in Athlone IT. This test tracks how well a person tolerates a glucose (sugar) load. We ask participants to arrive to the lab fasted for the previous 8 hours. We put a line in their arm and take fasting blood samples. We then give them a sugary drink and take more blood samples every 30 minutes for 3 hours. We look at how much their blood sugar rises in response to the drink, and how much insulin (the hormone our body produces to help us deal with sugar) their body produces to help bring their sugar levels back to the fasting level over a 3 hour period. The fitter and healthier a person is, the less insulin they need to produce to do this job. These people are called insulin sensitive. From the research we have done to date we expect that all of our lovely participants will be far more insulin sensitive after 8 weeks of training, which means they are much more metabolically healthy, and have a significantly reduced chance of developing diabetes.
However, people who are unfit, overweight or pre diabetic are insulin resistant, which means their insulin doesn’t work very well. When we do this test we see that they have to produce massive amounts of insulin to control their blood sugar levels. Over time it becomes very hard for the body to do this and blood sugar levels start to rise. If it rises high enough they become pre diabetic and then finally diabetic. The good news is exercise (muscle contraction) does the very same job as insulin in terms of controlling our blood sugar. My advice to everyone is if you want to stay healthy and free from insulin resistance and diabetes, you need to move your muscles! In todays society where sugar is found everywhere it is even more important to be physically active! Its a simple thing like walking every day that had a massive impact on your health! Just some food for thought.
