Amino acids before strength training increase its effect
A study shows more effective muscle building if proteins and amino acids are taken immediately before strength training. The notably already aged study by Kevin D. Tipton on "Timing of amino acid-carbohydrate ingestion alters anabolic response of muscle to resistance exercise" shows that protein synthesis may be more effective when essential amino acids are taken immediately prior to resistance exercise. Particularly relevant is the L-leucine content of the amino mixture. L-leucine is regarded as a triggering substance for muscle protein synthesis and thus activates the desired build-up processes. In Tipton's study, free amino acids were used, which is crucial for timing. Intact proteins such as WHEY ISOLATE 94 would therefore have to be taken with a corresponding lead time of approx. 60 to 90 minutes before training, as the necessary digestion time has to be taken into account.
SPONSER recommends the following products for this purpose:
AMINO EAA tabs and EAA INSTANT drink are taken immediately before and, if the training lasts longer, also during the load. They support the growth and the preservation of the muscle mass and contain all essential and semi-essential amino acids in free form. Both the tabs and the instant drink do not supply any extra energy and concentrate on the essential: essential amino acids. This makes them suitable for athletes, who want to limit their protein supply to the necessary minimum and do not want to take any additional calories.
PRO RECOVERY, which can be taken before strength training. The unique combination of the different protein components whey, egg and casein in a ratio of 1:1:1 as well as colostrum and egg-potato protein hydrolysate enable an optimal protein mix for growth and maintenance of muscle mass.
