Workout enhances brain function in overweight and overweight people
New findings out of the University of Tübingen show that, on top of its benefits for metabolic process, mood, and basic health, workout likewise enhances brain function. In recent studies, scientists learned that obese and overweight individuals are prone to insulin resistance in the brain, where it provides info about current dietary status, in addition to the remainder of the body. So scientists wanted to understand whether exercise can improve insulin level of sensitivity in the brain and improve cognition in overweight individuals.
In the existing study, led by Dr. Stephanie Kullmann, 22 inactive adults with overweight or obesity (an average BMI of 31) went through 2 brain scans prior to and after an 8-week exercise intervention, consisting of biking and walking. Brain function was determined before and after using an insulin nasal spray to investigate insulin level of sensitivity of the brain. Individuals were also evaluated for cognition, state of mind, and peripheral metabolism.
Although the workout intervention only led to a marginal weight loss, brain operates crucial for metabolism “stabilized” only after 8-weeks. Exercise increased regional blood flow in areas of the brain important for motor control and benefit procedures, both of which depend upon the neurotransmitter dopamine. Dopamine is a crucial neurotransmitter for discovering new motor abilities and in reward-related knowing and this research shows that workout significantly enhances dopamine-related brain function. One area in particular, the striatum, had actually improved level of sensitivity to insulin after the 8-weeks of workout such that the brain response of an individual with weight problems after workout training looked like the reaction of a person with normal-weight. Interestingly, the higher the enhancement in brain function, the more tummy fat an individual lost during the course of the exercise intervention. Behaviorally, participants reported an enhancement in state of mind and job changing, which is an indication for better executive function.
“The bottom line is that exercise enhances brain function,” said Kullmann. “And increasing insulin level of sensitivity in dopamine-related brain areas through workout may assist reduce the threat of a person to establish type 2 diabetes, together with the benefits for mood and cognition.”
