For people with type 2 diabetes, a simple exercise habit may significantly improve insulin sensitivity and brain health. A groundbreaking new study suggests that physical activity can enhance brain function by improving how brain cells respond to insulin.
The research found that exercise activates specific cellular processes in the brain linked to insulin function. Insulin is primarily known for regulating blood sugar, but it also plays a crucial role in brain health. When brain cells become less responsive to insulin, cognitive function can decline.
Researchers recruited 21 sedentary adults and asked them to participate in a two-week exercise program, which included 12 supervised cycling sessions at moderate to high intensity. Before and after the program, they consumed a glucose drink to stimulate insulin production and blood samples were collected to measure changes in brain insulin sensitivity.
The results showed that participants experienced improved insulin sensitivity throughout their bodies, including increased levels of a protein called Akt in their neuronal extracellular vesicles. These changes indicated improved insulin sensitivity in the brain, which was even more pronounced after consuming the glucose drink.
In addition to brain-related benefits, the study found that participants also experienced improved overall blood sugar control and weight loss. The findings suggest that exercise has the potential to improve not only physical health but also cognitive function.
While the study’s limitations need to be addressed in future research, the results are promising and support the idea that regular physical activity can have a positive impact on brain health and metabolic well-being.
