High-intensity exercise positively affects insulin sensitivity by enhancing the body's ability to utilize glucose effectively. This type of exercise promotes the uptake of glucose into muscle cells, improving overall metabolic function. Additionally, high-intensity workouts can stimulate the release of hormones such as epinephrine and norepinephrine, which further help in glucose regulation. Improved insulin sensitivity reduces the risk of developing type 2 diabetes and aids in weight management. Integrating high-intensity exercise into fitness regimens can lead to long-term health benefits by maintaining better glucose control and overall metabolic health.
