All amino acids are found in the food we eat, in the form of protein. Protein is made up of chains of amino acids strung together, and when eaten they get digested and absorbed into the system as single units called amino acids. Once in the body, these amino acids are used predominantly for building body tissue such as muscle development, though there are other uses for amino acids such as for energy (~5%) and enzymes. Under certain condition there is a greater requirement for protein and amino acids, such as during periods of rapid growth like in teenagers, while undertaking resistance training, and when there is tissue repair such as after an injury or illness.
Is it true certain amino acids stimulate growth hormones in teenagers?
Some research on certain amino acids has shown a benefit to weight gain and muscle growth, though there is very little evidence to prove that any amino acid supplement works in these ways. There are three amino acids that have been claimed to increase the release of growth hormone in children and teenagers; they are arginine, lysine, and orthinine. An injection of arginine is used to stimulate growth hormone release in children with a deficiency, working for only a short period of time. However, there is no evidence that an oral dose of these amino acids has the same effect. Supplements with these amino acids contain very low doses. Teenagers will get the greatest benefit out of increasing their total energy intake, which will in turn increase their protein intake to assist with muscle growth.
Any athlete (professional, amateur or weekend warrior) searching for legitimate ways of enhancing their physical performance has undoubtedly heard of creatine. If used properly, this safe, legal and effective supplement will enhance your athletic performance in ways never before imagined.
Scientific research has shown that creatine promotes muscle growth, improves athletic performance and accelerates recovery following strenuous exercise. Moreover, new research is now showing that creatine enhances overall anabolic (tissue building) potential and promotes good health and longevity.
However, in order to reap creatine's full range of benefits it is imperative that one first sets the stage - metabolically speaking. Unfortunately, this information is not easily accessed by the layperson. Moreover, many creatine informational websites misinterpret existing scientific studies and disseminate potentially harmful advice about the "proper" use of creatine.
Dr. Alfredo Franco-Obregón now shares his insights about sports supplementation with a guide that reveals the truth about creatine and the many ways in which it can help you achieve your true athletic potential - at any age. Optimize your creatine use!
Taking exorbitant amounts of creatine is pointless and ultimately unsafe. Most of us can get away with taking much less creatine than suggested by the manufacturers, without sacrificing any of the gains.
The guide is written so that even a layperson will quickly learn how to implement a straightforward supplementing regimen into their daily routine that will allow them to reap creatine's full range of benefits at the most affordable price and with the least amount of stress to their system.
For the more scientifically minded, this comprehensive guide also analyzes the most recent scientific studies examining the effects of creatine supplementation on athletic performance and overall health. Obtaining this information is the first step to opening the door to a longer, more fruitful, athletic career.
Food for a human is like fuel for a car - you want the best blend for top performance. For training, you need more fluid and more energy (carbohydrate and fat) than your less physically active friends. You also need more protein than a person who is not training.
Energy needs increase as the amount and the intensity of exercise increases. Whether your sport requires short bursts of effort or is an endurance event, carbohydrate is the main source of energy.As you consume more food to meet your energy needs, you will consume more protein, vitamins and minerals. Athletes who eat enough food to meet their need for energy to grow and train and who choose a variety of foods from the four food groups consume an adequate amount of all nutrients.
