The serum is always the best for building muscle

The serum is always the best for building muscle?

The serum protein remains the most popular with bodybuilders. Recently, some scientists have compared the effects of fast-digesting protein (hydrolyzed whey and soy) and slow digestion (micellar casein) on mixed muscle protein synthesis, both at rest and after training with resistance training.  Eh yes, soy protein is considered a "fast" ...

Three groups of healthy young men who followed a program of weight training for one leg and then drank a mixture containing 10 g of essential amino acids in the form of hydrolysed whey, micellar casein or soy protein isolated. The three beverages did not contain the same amount of protein, but rather the same dose of essential amino acids. Interesting. Well, resting mixed muscle protein synthesis was higher in subjects who had taken the proteins faster. In fact, the serum has stimulated the process more than the casein and soy (respectively 93% and 18% more). After training, the results were similar: the serum has enhanced muscle protein synthesis approximately 122% more than the casein and 31% higher than the soy.

These data confirm the findings of another study which analyzed the effects of supplementation with protein of 10 weeks of training. The scientists compared the effects of whey isolate and hydrolyzed casein on strength, body composition and blood glutamine during 10 weeks of supervised training with resistance training. In a double-blind protocol, 13 male amateur bodybuilders have added to their normal diet isolated 1.5 g of whey or casein per kilogram of body weight. 

Whoever had taken the serum gained more lean mass and lost more fat body of the casein group, in addition to experiencing a significantly greater improvement of the strength in all of the tests, even in those in which the changes in strength were expressed in terms of body weight change.

But the question is: what is the difference between whey and soy protein are both fast and the doses contained the same amount of essential amino acids? Scientists speculate that the serum is able to stimulate muscle protein synthesis more soy because it is rich in branched chain amino acids total (about 7% more) and leucine (about 28% more). Thus, the leucine might act as an activator to maximize the stimulation of protein synthesis. But, then I say, why not simply add more BCAA and leucine to soy or casein? But, in short, who has time for that? So, here you go: from the training data shows that whey protein is piùanaboliche and, as regards the soy protein ... now its no longer interest anyone!

Fitness for health prevention

Fitness for health prevention One of the evils prevalent fruit of modern society is represented, paradoxically, from the Wellness observed in its most negative: the sedentary lifestyle . In support of this statement can be seen as the main cardiovascular disease and metabolic the last 50 years, except in cases amenability to genetic demonstrable, are the result of sedentary lifestyles and improper, identifiable beyond latitudes, but especially evident in affluent societies like ours.   Recent research statistics but also simply because of our experience, we understand how the question of why you do not do physical activity l 'interviewed / to respond, often in direct proportion to the increase of' chronological age, there is a lack time: well then, this response often mask actually a lack of motivation. Our ancestors, of which carry the memories at the genomic level, were, for reasons of survival, real forerunners of modern athletes. Common tasks such as running, climbin...

Boxing training to weight loss at home

Boxing training weight loss at home Hi all, previously you talk about the properties of boxing training weight loss and although it is a sport in which training partners are needed, we can practice some of his moves in the comfort of home and come out a little routine of our training usual. The first thing to learn is the position of the guard, which allows us to be covered from shocks. To do this you have to stand up with legs apart at shoulder height, slightly bending your knees and leaning on toes. After your left leg forward and tilts the body. This reduces the body surface that may be struck. Then bend your elbows, keeping them close to your body to protect your sides. Your left hand should be approximately the height of your forehead and thus protect you from punches arriving frontally or your left side. The right hand should touch your chin to protect that area, since it is one of the most vulnerable, with a small blow the fight is over. Boxing , consists basic...

The ketosis diet plan

The ketosis diet plan Usually people consider a ketosis diet plan as a short-term diet option. The truth is this diet plan can be sustained over long periods and you can use it to get a bodybuilder physique. The idea of this diet is to limit your carbohydrate intake for most of the plan followed by adding a small subsection were more energy will come from fat and protein. By managing low carbohydrate periods with high-fat and protein, and then subbing in small break. Work carbohydrates are allowed, you can work to maintain energy levels and target fat cells. This can help you to get lots of energy to work out and define your muscles very well.  When you stop eating carbs your body will begin to release ketones. These are released in the mitochondria of your liver cells and they will begin to break down any fatty acids in your system which will give your body more energy to work out for longer with less pain. Carbohydrates only work to limit the production of ketones and a...
