The Role of Exercise Snacks in Glycemic Control
Exercise snacks, defined as short bursts of intense physical activity, can significantly enhance glucose management. Research reveals that these brief bouts of exercise help deplete glycogen stores in muscles and the liver, leading to improved insulin sensitivity. A study mentioned highlights that performing short exercise sessions, such as squats throughout the day, was more effective in managing blood sugar levels compared to a longer, continuous walk. This finding underscores the effectiveness of incorporating frequent, high-intensity movements within daily routines to better regulate glucose transport and maintain metabolic health.
