In the field of endurance sports, every small advantage is crucial. From running long distances to competing in triathlons or participating in long-distance cycling, athletes are constantly looking for ways to improve their performance and endurance. In recent years, beta-alanine supplementation has gained popularity as a tool to achieve this. In this article, we will explore what beta-alanine is, how it can benefit endurance athletes, and how you can effectively incorporate it into your training routine.
What is it?
Beta-alanine is a non-essential amino acid that occurs naturally in our body and can also be obtained through diet. Its main function is to increase carnosine levels in the muscles, which helps reduce lactic acid accumulation during intense exercise and delay muscle fatigue.
For endurance athletes, beta-alanine supplementation can be beneficial, as it allows them to maintain an intense training pace for longer before feeling fatigued. When incorporating it into your training routine, it is important to consider the appropriate dosage and timing of consumption to maximize its positive effects.
Carnosine:
Beta-alanine plays a crucial role in the synthesis of carnosine in the human body. Carnosine, a dipeptide present in high concentrations in skeletal muscles, is formed from the combination of beta-alanine and histidine.
When supplementing with beta-alanine, it is transported to the muscles through the bloodstream. Once there, it binds to histidine with the help of carnosine synthetase, forming carnosine. This carnosine is stored in muscle cells. During intense exercise, the muscles produce lactic acid due to anaerobic metabolism. This acid can lower intracellular pH, causing fatigue and reduced performance. This is where carnosine plays a crucial role by neutralizing lactic acid and maintaining muscle pH at an optimal level for performance.
Therefore, beta-alanine supplementation can increase carnosine levels in the muscles, thereby improving their ability to tolerate lactic acid during intense exercise. This translates into improved performance and reduced muscle fatigue in endurance sports and high-intensity activities.
The benefits of supplementation:
- Increases sensitivity to minerals, especially calcium, in muscle fibers.
- Helps reduce exercise- and physical activity-induced fatigue, delaying its onset.
- It has been shown to have positive effects on increasing strength and muscle growth.
- Consuming beta-alanine after training stimulates the receptors of the neurotransmitter GABA, which slows down the nervous system and facilitates the recovery phase.
- It acts as a powerful antioxidant by combating free radicals in the body.
How can you supplement effectively with Beta-Alanine?
Beta-alanine is a supplement that works through accumulation. In other words, we must take it daily and consistently for several weeks in order to saturate carnosine levels. The general dosage for improving endurance usually ranges from 3 to 6 grams per day.
