How much does regular exercise improve HbA1C levels?

Regular exercise has been shown to have a significant impact on HbA1c levels, particularly in individuals with type 2 diabetes or those at risk for the condition. The average improvement in HbA1c levels due to consistent physical activity is often cited around 0.8%. This reduction is attributed to exercise enhancing the body’s insulin sensitivity, allowing for better glucose uptake by the cells, and ultimately leading to lower blood glucose levels over time.

Engagement in regular aerobic or resistance exercise helps to regulate the body’s glycemic control and contributes to weight management, which is another crucial factor in controlling blood sugar levels. The mechanism involves various physiological changes, including increased muscle mass, reduced inflammation, and improved metabolic function, all of which support better glucose regulation.

The cited figure of 0.8% is a general estimate based on research evidence and practical studies, which indicates that lifestyle modifications, including exercise, can lead to meaningful improvements in HbA1c levels. This is especially instrumental for patients managing diabetes as it can help in minimizing the risks associated with long-term high blood sugar levels.
