Scientists found that those on the low - carb diet experienced
higher rates of protein breakdown and lower rates of protein synthesis, resulting in less overall muscle growth than their higher - carb counterparts.
In the most commonly sold supplement form, BCAAs require no digestion and are quite rapidly absorbed into the bloodstream — which is really neat because it means BCAAs can be used as an immediate energy source during your training sessions, and they will quickly act to decreasing
the rate of protein breakdown.
This nutrient - packed beverage dramatically slows
the rate of protein breakdown and supports muscle growth.
Also, BCAA reduce
the rate of protein breakdown.
These qualities are particularly precious when you are on a fat cut - down diet regime and
the rate of protein breakdown exceeds the rate of the synthesis, resulting in muscle loss.
Leucine can be used as an energy source for muscles, but more importantly, it slows
the rate of protein breakdown in skeletal muscle tissue.
This response seems to happen because the continued rise of intracellular amino acid levels signal to limit
the rate of protein breakdown.4 It is thought that this signal to decrease breakdown is due to the action of insulin and has no limit, as protein breakdown will continue to decrease with ever increasing protein intake.
«A net gain in protein balance (i.e., synthesis minus breakdown) is called an anabolic response, as opposed to a catabolic response caused by
the rate of protein breakdown exceeding the rate of protein synthesis.
