Dapagliflozin, an SGLT2 inhibitor, has been shown to have several effects on exercise performance, particularly in individuals with type 2 diabetes and heart failure. Here are the key points regarding its impact on exercise performance:
Improved Physical Function: Studies have demonstrated that dapagliflozin can improve physical function in people with type 2 diabetes. This improvement is often assessed using the modified Physical Performance Test, which measures various aspects of physical capability.
Enhanced Exercise Capacity: Dapagliflozin has been found to enhance exercise capacity in patients with heart failure. This includes improvements in peak oxygen consumption (VO2) and other measures of cardiovascular performance during exercise.
Increased Use of Fatty Acids: Dapagliflozin increases the use of fatty acids for energy during exercise, which can be beneficial for endurance athletes. This shift in energy metabolism helps preserve glycogen stores and may improve overall endurance performance.
Improved Cardiac Function: The drug has been shown to improve myocardial performance during exercise, which can enhance exercise tolerance and overall cardiovascular health. This is particularly beneficial for individuals with heart failure, where improved cardiac function can lead to better exercise outcomes.

Mitigation of Muscle Atrophy: Exercise has been found to mitigate the skeletal muscle atrophy that can be induced by SGLT2 inhibitors like dapagliflozin. This suggests that combining dapagliflozin with regular physical activity can help maintain muscle mass and function.
Potential for Use in Athletes: Some studies have explored the potential of dapagliflozin as a performance-enhancing agent for athletes. While the primary use of dapagliflozin is therapeutic, its effects on energy metabolism and cardiovascular function could be of interest in the context of athletic performance.
In summary, dapagliflozin can positively impact exercise performance by improving physical function, enhancing exercise capacity, increasing the use of fatty acids for energy, improving cardiac function, and mitigating muscle atrophy. These effects make it a valuable medication for individuals with type 2 diabetes and heart failure who are looking to maintain or improve their physical activity levels.
