BCAA-XT is 100% fermented instantized Leucine, Isoleucine and Valine in 2:1:1 ratio. BCAA-XT have been proposed to benefit performance in several ways including as a stimulant for muscle protein synthesis through leucine. BCAAs may also prevent muscle protein breakdown and reduce markers of exercise induced muscle damage. BCCA’s have the potential to act as a fuel source for muscles during exercise, although the research surrounding this is inconclusive. Lastly, BCAA’s may interfere with the transport of tryptophan into the brain, reducing the synthesis of serotonin thereby reducing feelings of fatigue.
BCAA-XT supplementation with resistance exercise increases muscle mass
Increased muscle mass can benefit performance and comes from increasing the amount of the structural proteins in muscle, such as actin, myosin, troponin, etc, which are collectively known as the myofibrillar proteins.
The balance between synthesis and breakdown of these proteins over a given time period will determine changes in muscle size. Stimulating muscle protein synthesis, and thus resulting in a positive net muscle protein balance, is the metabolic mechanism for increased muscle size.
BCAA-XT - Spare glycogen during exercise
It has long been recognised that muscle glycogen levels are critical for athletic performance, particularly in moderate- to high-intensity events. Glycogen is the main source of fuel for the muscles during exercise and low levels contribute to fatigue. Therefore if BCAAs can be used in preference to glycogen at early stages of exercise, glycogen can be spared and used later. Thus exercise performance may be enhanced.
BCAA-XT - Help with weight loss
Many athletes are very concerned with body composition. If dieting is used to lose fat, both fat and muscle will be lost. For many athletes, loss of muscle is undesirable. So, if energy intake can be reduced, but muscle mass maintained, then a more desirable body composition may be attained.
