What are the uses of fitness amino acid chains

The main functions of the fitness amino acid chain include promoting muscle synthesis, relieving exercise fatigue, accelerating recovery, reducing muscle breakdown, and improving exercise performance. Branched chain amino acids, including leucine, isoleucine, and valine, are key components in protein synthesis and are particularly suitable for high-intensity training populations.

1. Promote muscle synthesis

Leucine, as the core component of branched chain amino acids, can directly activate the mammalian rapamycin target protein signaling pathway and stimulate muscle protein synthesis. Supplementing with branched chain amino acids after training can improve the utilization of amino acids in muscles and help with muscle fiber repair and growth. Clinical studies have shown that fitness enthusiasts who regularly consume branched chain amino acids experience a significant increase in muscle circumference.

2. Relieve exercise fatigue

Branched chain amino acids can penetrate the blood-brain barrier during exercise, competitively inhibiting the entry of tryptophan into the brain and reducing the production of the fatigue substance serotonin. Supplementing branched chain amino acids during endurance training can prolong exhaustion time and improve central fatigue. Marathon runners significantly reduced subjective fatigue after using branched chain amino acids.

3. Accelerated Recovery

Micro damage to muscle fibers after training can lead to delayed muscle soreness. Branched chain amino acids inhibit muscle protein degrading enzyme activity, reduce creatine kinase release after training, and shorten the recovery period. After supplementing with branched chain amino acids, strength trainers showed a significant reduction in muscle soreness within 48 hours.

4. Reduce muscle breakdown

In the state of calorie deficit, branched chain amino acids can be preferentially utilized by muscle tissue, inhibiting the activation of the ubiquitin proteasome system and preventing excessive breakdown of muscle proteins. During the weight loss period, athletes using branched chain amino acids can better maintain lean body mass and avoid a significant decrease in basal metabolic rate.

5. Improving exercise performance

Branched chain amino acids participate in the tricarboxylic acid cycle for energy supply, which can save muscle glycogen consumption during long-term exercise. Supplementing branched chain amino acids before resistance training can increase single training capacity and improve neuromuscular coordination. Multiple studies have shown that it can improve the training quality of athletes in explosive events.

Fitness enthusiasts are recommended to obtain branched chain amino acids from natural foods such as whey protein, eggs, beef, etc. If necessary, supplements with a purity exceeding 5:1:2 formula can be chosen. During use, it is necessary to ensure a daily protein intake of at least 2 grams per kilogram of body weight, combined with carbohydrate co absorption. The best effect is to supplement 3-5 grams before and after high-intensity training for 30 minutes, but for those with abnormal kidney function, the total amount should be controlled. Long term users should regularly monitor liver and kidney function to avoid overlapping with other nitrogen metabolism supplements. Daily attention should also be paid to comprehensive recovery measures such as stretching and sufficient sleep after training.
