Randomized Controlled Trial to Study the Acute Effects of Strength Exercise on Insulin Sensitivity in Obese Adults
December 1st, 2023
This study describes a randomized controlled trial protocol aiming at assessing the acute effects of strength exercise volume on insulin sensitivity in obese individuals.
Our research has been centered on studying how resistance exercise effects glucose metabolism and its potential as a tool to improve overall health. Our primary objective is to provide the general public with practical ways to enhance their metabolic health through resistance exercise. Our research protocol aims to evaluate the impact of varying volumes of resistance exercise on insulin sensitivity and glucose responses.
We seek to determine whether reducing amount of exercise can yield similar benefits. To be more specific, we want to find out the extent to which insulin sensitivity improves when the exercise volume is reduced to one third of the original protocol. As most people find it hard to fit exercise into their schedule, reducing exercise volume, and by default, the time spent in the gym could improve people's adherence to exercise.
If the metabolic response were comparable between high and low volume resistance exercise, in other words, reducing resistance exercise volume might be time efficient for improving one's metabolic health. Our next steps moving forward, you'll be to study the effects of effort on the improvements of insulin sensitivity in response to resistance exercise. Do we need to push ourselves very hard during a session to observe improvements or can we perform it with less effort and still get better?
We're exploring whether reducing resistance exercise volume is time efficient for improving metabolic health, and if can result in long-term improvements. This can lead to more confidence in exercise for those who can spend less time achieving better health.
