ОглавлениеWHEY, WHAT'S THAT?
Whey is an English term which refers to the protein in milk. Consequently Whey is always present in milk. Approximately 20% of the milk protein consists of whey. It has a very high biological value and is therefore absorbed very quickly by the body. Due to the high biological value, the body can split it very well into the body's own proteins. Whey is very rich in BCAA and glutamine.
What does Whey do? It causes an excitement of protein synthesis and insulin secretion. However, insulin secretion is not as high as drinking pure sugar. Through this effect, the body enters an anabolic state. Which means that the body now prefers cell and muscle growth. Whey protein concentrate is extracted from milk by ultrafiltration.
WHO NEEDS IT?
Athletes benefit more from Whey protein. Whether in powerlifting or other physically demanding sports, everyone can benefit from it. Even underweight and sick people can benefit from it, since it stimulates the body to its own protein synthesis.
HOW WHEY INGEST PROTEIN AND ITS DOSES?
The simplest form of whey protein is mixed in powder form as a drink. To do this, the powder is poured into a blender and stirred together with either water or other liquids. Mixing leads to a much better shake. Mostly the preparation is creamier and has fewer lumps in the shake.
Dosage: 0.3g to 0.6g per pound of body weight is described as the recommended amount. It takes at least 20g to 30g to stimulate protein synthesis. To achieve its most intake recommendation, an intensive full body workout has to be completed.
Let's start with an athlete with 80kg body weight. This results in the following calculation.
0.3 * 80 = 24g whey
The older an athlete gets, the higher the dosage must be, because the body no longer reacts so sensitively to the presence of Whey.
WHY WITH DEXTROSE AND WITH WATER?
Dextrose increases insulin secretion, so you need a little less whey, but do not go below 20g whey for protein synthesis. When taking Whey with water, presence of fat in milk must be considered as it can slow down the effect of Whey.
WHY AFTER THE TRAINING?
Studies have shown that post-workout intake improves recovery and helps build muscle. The protein arrives in the cells in about 45 minutes. Here you should also be cautious of having little fat in the shake and relatively drink it on an empty stomach. Theoretically, you can also organize the entire protein intake during the day via Whey Shakes.
WHAT IS WHEY ISOLATE?
It is obtained by an ion exchange process and thereby other substances can bind to the protein. Microfiltration ensures a higher level of purity, which means less fat and carbohydrates in the powder. Protein content of 91-97% is expected, but an isolate makes more sense in a diet that is already going towards the end, and calories going down already.
