How does resistance exercise influence basal insulin levels?

Resistance exercise plays a key role in regulating insulin levels and improving insulin sensitivity. Engaging in this type of physical activity promotes various physiological adaptations, including changes in muscle mass and metabolism that contribute to lower insulin resistance.

When resistance training is performed, it enhances the muscles' ability to uptake glucose from the bloodstream, thereby improving metabolic control. As a result, this increased uptake can lead to a modest decrease in basal insulin levels. The body becomes more efficient at using insulin, which means that less insulin is required to maintain normal blood sugar levels, leading to improved overall metabolic health.

This effect can be particularly important for individuals with or at risk for insulin resistance or type 2 diabetes, as it indicates that regular strength training can have beneficial effects on insulin regulation, contributing to a healthier metabolic profile.
