Effect of a leucine-enriched essential amino acids mixture on muscle recovery

[the purpose]
This study was conducted to verify whether the intake of leucine-rich essential amino acid (LEAA), which is known to increase muscle protein synthesis, reduces muscle damage and promotes recovery by improving muscle damage.

Subjects and Methods
This was a 5-week, double-blind, randomized crossover study. Ten untrained males (age: 10±23.0 years) performed maximal arm flexion and extension exercises, 1.6 sets of 1 repetitions, using a muscle function evaluation device (Biodex®).

Subjects took 3.6 g of the supplement (LEAA or placebo) three times daily for the first day and the following seven days. Changes in serum creatine phosphokinase (CPK) activity and myoglobin concentration, as markers of muscle tissue damage, were assessed before and after exercise and on days 7, 1, 3, 1, and 2.

[result]
The relative change in serum CPK activity on the 5th day was significantly lower in the LEAA group than in the placebo group.

[Conclusion]
Intake of LEAA suppressed the increase in blood muscle damage markers caused by exercise, suggesting that intake of LEAA reduces muscle damage after exercise and aids muscle recovery.

This article explains the role that the amino acid leucine plays in muscle recovery. It promotes muscle protein synthesis, aids in damage recovery, and supports post-training recovery and conditioning.
[Paper introduction] Effects of leucine-rich essential amino acids on anabolism and catabolism in human skeletal muscle after resistance exercise

2021.07.06

Resistance exercise transiently activates the anabolic and catabolic systems of skeletal muscle. Leucine-rich essential amino acids (LEAAs) have been reported to stimulate the muscle anabolic system at lower doses than whey protein. However, resistance exercise-induced…
[Paper introduction] Essential amino acids rich in leucine improve recovery from muscle damage after exercise in young men independently of muscle protein synthesis

2021.07.06

Leucine-rich essential amino acids (LEAA) rapidly increase muscle fiber protein synthesis after exercise, which is important for muscle repair and recovery. However, no studies have been conducted in the general population to show that LEAA simultaneously increases muscle fiber protein synthesis and recovery from muscle injury.
[Paper introduction] Cystine attenuates oxidative stress-induced tight junction permeability and intestinal inflammation in Caco-2 cells

2021.07.06

Oxidative stress in the intestine produces proinflammatory cytokines and increases tight junction (TJ) permeability, leading to intestinal and systemic inflammation. Cystine is a substrate for glutathione and inhibits inflammation, but it is unclear whether cystine locally improves intestinal barrier dysfunction. ...
