Why Is Beta-Alanine Important for Reducing Fatigue During Rides?
The underlying mechanism involves the role of carnosine, a dipeptide composed of beta-alanine and histidine, which acts as a pH buffer. During intense exercise, lactic acid builds up in the muscle tissues, leading to a decrease in pH and resulting in fatigue. By increasing carnosine levels, beta-alanine helps to maintain a more stable pH environment, allowing cyclists to perform at higher intensities for longer durations without succumbing to fatigue.
Furthermore, research indicates that the ergogenic effects of beta-alanine are particularly pronounced in activities lasting between 1 to 4 minutes, which is a common duration for high-intensity bursts during a cycling event. A meta-analysis in the “International Journal of Sports Nutrition and Exercise Metabolism” confirmed that beta-alanine supplementation improves performance metrics such as power output and total training volume, directly linking it to enhanced endurance and reduced fatigue in athletes (Saunders et al., 2017).
