How do both aerobic and resistance exercises affect insulin sensitivity?

Both aerobic and resistance exercises have been shown to positively influence insulin sensitivity, making the assertion that they both cause a moderate increase in insulin sensitivity accurate.

Aerobic exercise, which includes activities like running, cycling, and swimming, enhances the transport of glucose into cells by increasing the efficacy of insulin. It also helps regulate body weight and reduces body fat, both of which are important factors in maintaining or improving insulin sensitivity.

On the other hand, resistance training, which involves exercises that build muscle strength, also improves insulin sensitivity through mechanisms such as increasing muscle mass. Greater muscle mass means an increased capacity to utilize glucose, as muscles play a pivotal role in glucose uptake, especially after exercise.

Both forms of exercise contribute to metabolic health and enhance the body’s ability to manage blood glucose levels. Regular participation in both aerobic and resistance training leads to cumulative benefits that effectively augment insulin sensitivity beyond what either form of exercise could achieve alone. This holistic approach to physical fitness is essential in reducing the risk of metabolic disorders, including type 2 diabetes.
