Does Exercise Lower Insulin Levels?

Does exercise decrease insulin levels? In summary, during exercise there is a decrease in plasma insulin due to increased sympathetic activity and inhibition of pancreatic insulin release. This decrease in insulin does not impede muscle glucose uptake which occurs via mechanisms independent of insulin.

What happens to insulin levels after exercise? After exercise, insulin-independent glucose uptake by muscles remains elevated for approximately two hours. Insulin sensitivity also increases after exercise and remains elevated for about 24 hours in most individuals.
