Are Gels Really That Bad? w/ Dr. Mark Hearris - The Science of Getting Faster Podcast Ep. 9
Does the form in which we consume carbohydrates impact our ability to utilize it during exercise? The performance-enhancing effects of carbohydrates are becoming increasingly evident. For this reason, researchers and athletes continue to explore how we can maximize the benefits of consuming carbohydrates on the bike. In this episode of the Science of Getting Faster Podcast, we speak with Dr. Mark Hearris to discuss whether the form in which we consume carbohydrates impacts our ability to utilize them during exercise.
