Protein supplements


Athletes are increasingly concerned about the potential benefits of nutritional supplements. Many people are increasingly more aware of the new studies in nutrition and not doubt the importance of eating high quality protein and biological value as the basis for their daily meals. Thus , protein is the nutritional key that opens the doors of muscle growth .

The proteins are involved in important cellular processes such as the formation of enzymes , hormones , antibodies, contractile tissues (actin , myosin, tropomyosin , etc.), etc. .

Along with carbohydrates and lipids are the immediate principles which provide energy to our diet . Also provide the body elements regenerators plastics body tissues.

Proteins are macromolecules consisting of nitrogenous basic units called amino acids (joined in long chains ) . These amino acids can be of 2 types :

Essential : are amino acids that the body can not synthesize and must obtain them from the diet. They are:

- Isoleucine .
- Leucine .
- Lysine .
- Metiomina .
- Phenylalanine .
- Threonine .
- Tryptophan .
- Valine .
- Histidine .

Non- essential :

- Alanine .
- Arginine .
- Aspartic acid .
- Asparagine .
- Cysteine ​​.
- Glutamic acid .
- Glycine .
- Proline .
- Serine .
- Tyrosine .

Low levels of the 9 essential amino acids limit protein synthesis in the body, hence the importance of not only the quantity but the quality of the ingested protein. The protein -based animal products like eggs, milk , etc. . provide near optimum mixtures of amino acids . As to the amount below 20 % of total calories ingested intakes athlete maintain a state of muscle catabolism , totally inadequate for the athletic progress situation .

Recommended Daily Allowance (RDA) for protein.

Initially no attention to the nutritional quality lent disparate figures were given. Subsequently international organizations gave figures 1g . per kilogram of body weight specifying which should include proteins of animal and plant origin . Current recommendations vary committees nutritional experts worldwide , according to WHO 0.6 g / day / kg body weight.

The CDR is the RDA to ensure not suffer deficiency diseases and are based on some general statistics and be taken as baseline values. But athletes deviate from the average individual, both physical activity and the effects of exercise physiology has on your metabolism. So many sports dietitians recommend that a figure around 2gr/día/kg body weight.

I hope you find it helpful, comment and suggest . And do not forget to share !

Dietary supplements


Dietary supplements are foods marketed as capsules, tablets, ampoules , capsules, teas , oral solutions ... whose purpose is to supplement the normal diet . They are concentrated sources of nutrients or other substances with a nutritional or physiological effect. They are designed to meet a specific need : digestion, sleep , weight loss, tone ...
These are not drugs so they do not heal . Their goal is to improve the well-being and maintain good health. Dietary supplements are not essential in sports nutrition . A varied diet can ensure complete intake of nutrients essential to good physical condition. The problem often comes from deficiencies in the quality of our food , which is often depleted or unbalanced diet. The frequency and intensity of training sessions and competitions can therefore increase the risk of disability.

Are there a risk to consume dietary supplements ?
It is recommended to take these supplements on a defined period following employment recommendations on the label length . The choice of supplements should also be based on demonstrated need . Consuming dietary supplements in excessive doses , without a healthy supply of basic or no real need is certainly not without health consequences . This is the problem of self -medication ...

Fruits Food bodybuilder muscle development


Many bodybuilders overlook fruit, one of the best food groups for muscle development

Many bodybuilders believe that fruits are fattening. This is however not the case if you know which to choose, when to eat and how much.
Most practitioners know they should consume simple sugars before and after their weight training sessions - and many of them use sugar in their protein mixtures as well as in other forms of supplements pre-and post -workout. Overall, these products contain glucose and dextrose are excellent sources of simple sugars for training. Often, bodybuilders avoid fructose because this form of simple sugar is more easily stored as fat than other carbohydrates. Then to abandon the fruits because of their fructose content, there is not one!
Yet what many bodybuilders do not know is that the fructose content varies markedly from one fruit to another. Many fruits are low and they are full of other important phytochemicals (beneficial for bodybuilding micronutrients) that can only be found in almost any other food source. The problem associated with the consumption of fructose is also sometimes overestimates. When you eliminate the fruits of power, it not only removes the fructose and other sugars they contain, but at the same time, beneficial nutrients that contribute to muscle development.
Here's what to know about fructose, which consume fruits, when and why to put on your plate.
FRUCTOSE: MYTH AND REALITY What is wrong fructose? If the fruits are bad news is that they contain this simple carbohydrate that our body does not degrade in the same way as other sugars of the same type.The fructose is not used directly by the muscles, as c This is the case of glucose and dextrose these two simple sugars are readily converted into muscle glycogen, the storage form of carbohydrates in the muscles. When they contain a lot of glycogen recovery and hypertrophy are facilitated and the performance has improved during the next meeting. Glycogen also gives the muscles that bodybuilders looking rebounded as appearance.
Against by, when there is input of fructose, the isomer of glucose must first pass through the liver to be converted to glycogen. The problem arises when liver glycogen stores are full: fructose is converted to fat and helps to increase the size of adipocytes. Since it is often difficult to know when the liver glycogen stores peaked, many bodybuilders are choosing to completely avoid fruit. In fact, such an extreme measure may be counterproductive because overshadow the fruit back to forego the valuable nutrients they contain.
The best time to eat fruit is in the morning upon awakening. At this time of day, the rate of liver glycogen is low because the body has used this fuel as an energy source during sleep. This also means that the body will supply energy to muscle protein degrading. When we eat fruit at sunrise, it gives the body an alternative fuel source which helps to stop muscle catabolism.
Other conducive to fruit slot: 30 to 60 minutes before the workout, especially if you do not eat carbohydrate for several hours. Fructose will fill liver glycogen, thus ensuring a supply of glucose to working muscles and sparing muscle glycogen. Another advantage is that fructose does not block fat during exercise as does glucose. The following the end of the session slot also lends itself very well to the fruit: it is still preferable to be the richest fruits in glucose fructose. Glucose is more easily set aside in the form of glycogen and it will raise insulin levels, thereby ensuring better muscle development more effectively. To find out what fruits to select these different times of the day, see the table "picking fruit."
"MORE" FRUITS Many bodybuilders pros already know the benefits of the fruit. "I preferred as the main source of simple sugars," said Mustafa Mohammad. "I eat two for breakfast, usually bananas, but sometimes orange or kiwi." They are still consumed by Mohammad fruits as sources of simple sugars before and after his weight training sessions. "I eat before and after my workouts because I am of the opinion that it is necessary to consume mainly foods to meet nutritional needs. If I use supplements like protein shakes, is for convenience or when it is more difficult for me to swallow solid food. "
Muhammad noted that consumption of fruit has other benefits. "They whet my appetite so I eat more," he says. "When I diet, it is not always easy to swallow whole chicken and rice all I need to maintain my muscle mass while trying to lose fat. I find that I can eat more chicken if I also take a fruit with the meal. It is this sweetness that helps me to improve my diet. "
Mohammad also uses fruits for more tone. "When I feel tired or lethargic, I eat one or two fruits with a protein food. As there are fibers, I do not care excessive elevation of insulin: fruits are digested slowly enough that this effect does not occur. The fibers also slow down the rate of digestion of proteins, which provides a continuous release of amino acids. "Mohammad said that when lack of energy, the liver glycogen stores may be low, in which case it should not fear that fructose is stored as fat.
IN SUMMARY As some actors, fruits are not entitled to the respect they deserve. Too many bodybuilders exclude them from their diet because they are wary wrongly fructose they contain. While we do not suggest to binge, which would only overload and liver glycogen stores may increase fat mass. On the other hand, do not eat fruit would be a mistake: their nutrients, fiber and simple sugars, good for building muscle will help you progress in your bodybuilding provided that consumption is consistent with the recommendations of FLEX.

Do not forget the milk

Do not forget the milk

Athletes spend a fortune on protein supplements and fluid replacement beverages to enhance recovery and muscle building. Why spend a lot of money on sports supplements when you can get the same effect of milk?

Bodybuilding and milk

University in Canada, in a review of the literature, that low-fat milk enhances healing of weight training and exercise endurance, stimulates protein synthesis, and promotes post-exercise tissue repair.

Thirty years ago, scientists thought that the water better fluid replacement.

While it is still true to a large extent, and sports drinks are superior in some cases because they save water and energy and electrolytes. Milk may be the best, because it keeps the water balance for a longer period and provides a source of protein that can promote adaptation and tissue repair after exercise. Low-fat milk is an excellent sports drink for endurance sports, except in people who are lactose intolerant.

Creatine and build muscle mass

For athletes and fitness individuals thinking looking to add muscle mass and strength, and one of the most widely used supplements currently on the market is creatine. The way it works this supplement is its support for muscle cramps by increasing the levels of ATP while also working to reduce the amount of muscle depletion, which occurs after hard training.

What is

Creatine is a naturally occurring non-essential amino acids, which are stored in the skeletal muscle and heart, brain and testes. If not, contrary to popular belief, the steroid. In fact a lot of people do not realize that when you eat any kind of fish, meat or dairy products that consume this amino acid naturally.

Benefits of sport

What is essentially extension does not allow the muscles to work harder and recover faster. This is why the supplement has become a mainstay among athletes all over the world, both professional as well as amateur. Although creatine monohydrate in itself does not raise the amount of muscle mass, it helps in the process of building muscle mass by allowing the user to train more efficiently while having lower power output.

Health Benefits

- Many of the studies that report creatine monohydrate may improve heart muscle strength, and body weight, and endurance in patients with heart failure.

- There is also evidence that intravenous creatine after a heart attack may help in the function of the heart muscle maintenance and maintenance of heart rhythm.

- When combined with strength training because it helps to increase bone density.

- Early research indicates that creatine can have positive effects on patients diagnosed with depression. However, there is a need for more studies.

Side effects

This non-essential amino acid has few side effects official, although water retention is a big one. When consumed more than a decent amount of time, it will cause water retention, which may make muscles look bigger than it already is. There is no inherent danger in this, except for muscle contractions possible due to the large amounts of stored water. When the user stops this supplement, including in the system thereto they usually experience a small amount of weight loss due to water retention in reduced muscle. And on this he studied creatine over the past few decades, and the side effects on the long-term extension is still relatively unknown.

Although it has few side effects such as water retention and bloating, it is still very important to consult with your doctor before starting to use any extension or a new fitness routine physical.
