How does exercise impact insulin sensitivity?
Sources:
Exercise significantly improves insulin sensitivity. According to and , regular physical activity is crucial for warding off insulin resistance, which is often exacerbated by inactivity and energy imbalance. Exercise helps muscles efficiently dispose of glucose, reducing the burden on insulin to manage blood sugar levels 1.
Engaging in consistent exercise, particularly cardiovascular and resistance training, supports better insulin sensitivity and overall lipid profiles. This means that exercising not only aids in glucose management but also positively influences other aspects of metabolic health 2.
Furthermore, highlights that Zone 2 cardio—steady-state cardio where you can still breathe through your nose, done for 30 to 60 minutes, three to four times a week—can stabilize blood sugar levels and enhance insulin sensitivity. This allows for greater dietary flexibility without adverse effects on blood sugar 3.
