Best Exercise to Lower Blood Sugar
Managing blood sugar levels is crucial for individuals with diabetes, and exercise is a proven method to achieve this. Various types of exercise, including aerobic, resistance, and combined training, have been studied for their effectiveness in lowering blood sugar levels. This article synthesizes the findings from multiple research studies to identify the best exercise strategies for lowering blood sugar.
Aerobic Exercise for Blood Sugar Control
Low and Moderate-Intensity Aerobic Exercise
Research indicates that both low and moderate-intensity aerobic exercises significantly reduce blood sugar levels in diabetes patients. A study involving 20 participants showed that engaging in these exercises led to a notable decrease in blood sugar levels over a two-month period . Another study found that a single bout of low-intensity exercise reduced average 24-hour glucose concentrations more effectively than high-intensity exercise in type 2 diabetes patients .
Walking and Other Aerobic Activities
Aerobic exercises such as walking have been highlighted as effective and accessible methods for lowering blood glucose. A literature review of studies from 2015 to 2020 concluded that aerobic walking exercises, performed consistently over periods ranging from seven days to 25 weeks, significantly reduced various glucose indicators, including HbA1C and fasting glucose .
Resistance Exercise for Glycemic Control
Low-Intensity Resistance Training
Low-intensity resistance exercise has been shown to reduce hyperglycemia and improve glucose control over a 24-hour period. A study involving women with type 2 diabetes demonstrated that low-intensity resistance exercise significantly lowered glucose levels and reduced the prevalence of hyperglycemia compared to higher intensity resistance exercise and control sessions .
Combined Aerobic and Resistance Exercise
Combining aerobic and resistance exercises appears to offer superior benefits for glycemic control. A systematic review and network meta-analysis found that combined exercise modalities resulted in more pronounced improvements in HbA1c levels compared to either aerobic or resistance exercise alone . Additionally, an 8-week circuit training program that combined both types of exercise improved glycemic control, cardiorespiratory fitness, and muscular strength in type 2 diabetes patients .
Timing of Exercise
Afternoon vs. Morning Exercise
The timing of exercise can also influence its effectiveness in lowering blood sugar. A randomized crossover trial found that afternoon high-intensity interval training (HIIT) was more effective than morning HIIT in reducing blood glucose levels in men with type 2 diabetes. Interestingly, morning HIIT was associated with an acute increase in blood glucose levels, highlighting the importance of optimizing exercise timing .
Conclusion
In summary, both aerobic and resistance exercises are effective in lowering blood sugar levels in individuals with diabetes. Low and moderate-intensity aerobic exercises, such as walking, are particularly beneficial and accessible. Resistance training, especially at low intensity, also significantly improves glycemic control. Combining aerobic and resistance exercises offers the most pronounced benefits. Additionally, exercising in the afternoon may be more effective than morning sessions for managing blood glucose levels. Incorporating these exercise strategies can help individuals with diabetes achieve better blood sugar control and overall health.
