Another way that a high-acid diet can promote muscle loss is by increasing the release of cortisol, the primary catabolic hormone.
Scientific evidence shows that tyrosine steps up the production of catecholamines when muscle fatigue begins to set in.
Several studies have found that athletes who severely restrict carb intake suffer a loss of training intensity. On the other hand, the body is capable of using other forms of fuel.
Based on those findings, the authors suggest that it is more effective to take a supplement containing amino acids and carbs following a workout than before it.
Specifically, PEG is believed to enhance the gastrointestinal absorption of creatine by increasing permeability coefficients in the GI tract and across the sarcolemma.
The combination of large doses of GH and testosterone blunts myostatin, which leads to organ growth and a bloated abdomen.
Stress in its many guises is unavoidable. The body has numerous ways of dealing with the effects of stress, ranging … continue reading
It appears that following a strategic, timed protein intake before and after weight training doesn’t add to gains in muscular size and strength in elderly men who already get enough protein.
Until recently, no one had bothered to test the notion that 30 grams of protein or less is about all the body can handle after weight training. A new study tackled that issue in particular.
Many older people suffer from a condition called sarcopenia, which literally means “loss of muscle.” When that happens, overall body frailty and weakness become common, limiting the quality of life for older people
Labrada Nutrition, the most trusted name in sports nutrition, has introduced its new Lean Body Hi-Protein Energy Bars in four … continue reading
One of the most frequently asked questions when it comes to losing bodyfat is, How much carbohydrate should I be eating?
Studies show that engaging in resistance exercise, such as typical bodybuilding workouts, stimulates muscle protein synthesis for up to 48 … continue reading
Some studies suggest that other substances in colostrum ferry intact IGF-1 into the body, where it exerts its anabolic effects. Other studies have concluded that IGF-1 in colostrum doesn’t survive the digestive barrier.
About 25 years ago ornithine was a popular supplement among bodybuilders. It’s a free amino acid but is not commonly found in high-protein foods.
Those in the BCAA group showed significantly higher testosterone counts, along with lower counts of cortisol and creatine kinase, an enzyme that, when elevated, points to amplified muscle damage.
Taking the protein before and after training blocked the response of both active and total testosterone to the exercise, much the way that it happens in younger men
If you’re on an anabolic-steroid regimen, you’ll also probably bloat a bit, as steroids retain sodium in the body.
The authors suggest that the mechanism may involve an enabling of the muscle protein synthesis pathway, which makes sense because amino acids such as leucine are known to potently stimulate that pathway.
Peptides are a collection of amino acids strung together. Put two together, and you have a dipeptide; put three together, … continue reading
In their zeal to label commonly used bodybuilding supplements as potentially toxic, the physicians conducting the study conveniently sidestepped the steroid issue. So this case study is rated G for garbage.
The branched-chain amino acid L-leucine is the most important of the BCAAs for muscle growth. Research shows that taking even … continue reading
Take it immediately after exercise, and you get a rush of amino acids that leads to the creation of bigger and stronger skeletal muscle fibers. But whey isn’t just whey.
Science is finally catching up with the bodybuilding world. A new study verifies what muscleheads have known all along—that a … continue reading
The initial study of young, healthy subjects shows that eating large amounts of fructose may be far more dangerous for men than women.
