Creatine is used up as energy during high intensity exercise. Due to this usage, the amount of glucose required from glycogen is decreased a bit. This both preserves glycogen concentrations in skeletal muscle and reduces lactate production, which is produced when glucose is oxidized for energy. There do not appear to be any alterations in the bioenergetic status of muscle cells during low to moderate intensity exercise.
Studies conducted in vegetarians tend to show cognitive enhancement in youth, possibly due to a creatine deficiency, as compared to omnivores. Vegetarian diets have lower levels of circulating creatine prior to supplementation, but attain similar circulating levels as omnivores when both groups supplement. Building on the latter, supplementation of creatine monohydrate in a loading protocol (20g daily in orange juice) in omnivores does not alter levels of creatine in white matter tissue in the brain (test subjects: competitive athletes). In most of the parameters that vegetarians experience benefits, omnivores fail to experience statistically significant benefits, except possibly when sleep deprived, where the cognitive improvements rival that seen in vegetarians. Elderly people who are omnivorous may also experience increases in cognition to a similar level, in regard to long-term memory as well as forward number and spatial recall, although the study in question failed to find any significant benefit on backward recall or random number generation, the latter of which is a test for executive working memory.
Despite the fact that BCAAs may offer some benefits, you should keep in mind that these three amino acids are also present in any quality whey protein that you purchase. You can also get these essential amino acids from food sources. Basically, as long as you’re meeting your daily protein intake goals, you’re probably getting enough of these essential amino acids. Research supports this approach. So, why spend more on another supplement?
Most typical bodybuilding programs have way too many sets and reps and use the wrong exercises. However, if you lower the total volume, go heavier, and use compound movements as I’ve outlined above, there is nothing wrong with a body-part split for advanced lifters. In fact, it’s often less stressful to the joints than your average upper/lower split.
One study on 27 otherwise healthy men supplementing creatine (0.3g/kg loading for a week, 0.05g/kg thereafter for 8 weeks) with a thrice weekly exercise regiment noted that alongside greater increase in lean mass and power relative to placebo at 4 and 8 weeks, myostatin in serum decreased to a greater extent with creatine (around 17% at 8 weeks, derived from graph) than it did with placebo (approximately 7%). Increases in GASP-1, a serum protein that inhibits the actions of myostatin by directly binding to it, were not different between groups.
The biggest mistake among young would-be bodybuilders is overdoing it, followed by not learning the proper techniques. Take those breaks and follow the correct form, or you'll give your body stress and injuries instead of muscle. Also make sure you're getting a large but balanced diet. Teens going through growth spurts need lots of food, especially when they're working out.
After all, you’ve probably seen the countless workouts, diets, supplements, programs, products and people claiming that super fast muscle growth is possible. You’ve probably also seen the click-bait headlines (“How To Build 20lbs Of Muscle In Just 6 Weeks!”) and the unbelievable transformations of supposedly “natural” people (bodybuilders, celebrities, athletes, fitness gurus on social media, etc.) that clearly prove it can happen faster than this.
The creatine transporter is a sodium and chloride dependent membrane-associated transporter that belongs to the Na+/Cl-dependent family of neurotransmitter transporters. In muscle cells and most other cell types, the isomer of the creatine transporter is known as SLC6A8 (solute carrier family 6, member 8). SLC6A8 is encoded by the gene present on the Xq28 region of the human X-chromosome and is expressed in most tissues. A related gene encoding a creatine transporter variant has also been identified at 16p11.1 that is expressed exclusively in the testes. These two transporters share 98% homology.
Entry into neural tissues in general is mediated by the secondary creatine transporter (CrT-2) known as SLC6A10, which is the same transporter that is active in a male’s testicles. CrT-2 belongs to the family of SLC6 transporters that act to move solutes across the membrane by coupling transport with sodium and chloride. Genetic deletions in the 16p11.2 region, which encodes both SLC6A8 and SLC6A10 can result in severe mental retardation in humans and is one of the causes of “Creatine Deficiency Syndrome.” Creatine Deficiency Syndrome is not only caused by lack creatine transporter expression, however, as creatine synthesis is also critical for neural function.. Retardation caused by defective creatine synthesis can be reversed with creatine supplementation and dietary changes.
It is equally important, if not more so, to ensure that you supply your body with more protein than it is breaking down each day. Your body uses protein for many things daily, and when you are working out, your body may start to break down proteins to provide extra energy. But your body also requires proteins to create new muscle cells and repair damaged ones. Many bodybuilding supplements contain large amounts of protein to ensure that your body has plenty for all required processes. Jump to Our 10 Best Bodybuilding Supplement List
There appears to be some potential for creatine supplementation. However, many questions remain. Are there any long-term harmful effects from supplementation? Is there a point where enhanced performance levels off from long-term supplement usage? What effect does "stacking" or taking two ergogenic aids simultaneously have on the body? What happens if you immediately stop taking the creatine supplement? Is the enhanced performance great enough to warrant the expense of the supplement? Until further research answers these questions, creatine is not recommended for the average athlete.
Progression – Throughout the course of your lifting career you should consistently strive for progress both mentally and physically. Initially, you may find that you’re incessantly focused on nutrition and training but as you progress in both maturity and muscular development, you should be focused on improving the balance between lifting and your life. It’s never about having an all or nothing mindset, balance must be incorporated in all aspects but this takes times to develop and occurs with progression over time.
Try this little exercise some time: follow the supplement plan provided above for at least three months. Then quit all supplement use for a further three months and watch what happens. Sure, most supplement marketing involves hype and some companies make laughably outrageous claims, but there is no secret as to why the supplement industry is booming. Supplements work.
Creatine kinase is expressed in eyes. The eyes can take creatine up from the blood via two different transporters, the classic SCL6A8 (creatine transporter) and MCT12. It seems that expression of the receptors and accumulation of creatine occur in a relatively higher level in photoreceptors, which perceive color. Similarly to many other tissues, they appear to protect the cells during periods of low oxygen availability.
This basic form of creatine comes in two forms, one of which involves the removal of the monohydrate (which results in creatine anhydrous) that converts to creatine monohydrate in an aqueous environment, but due to the exclusion of the monohydrate it is 100% creatine by weight despite creatine monohydrate being 88% creatine by weight, as the monohydrate is 12%. This allows more creatine to be present in a concentrated formula, like capsules.
When Katula started his research on whether weight training would improve quality of life for seniors, he realized that many had never even picked up a dumbbell. “They first had to learn how to use these big intimidating weights and machines,” he says. He recalls the story of one woman who protested that she couldn’t do the leg press machine. Finally, Katula persuaded her to sit in the machine and set the weight at 50 pounds. “I couldn’t believe how fast she whipped out 10 reps,” he says, “When she got out of that machine, she was two inches taller just from increased pride.”
Researchers found that 5g of creatine four times daily for a week (loading) before sleep deprivation for 12-36 hours was able to preserve cognition during complex tasks of executive function at 36 hours only, without significant influence on immediate recall or mood. A similar protocol replicated the failure to improve memory and attention, but noted less reports of fatigue (24 hours) and less decline of vigor (24 hours) although other mood parameters were not measured.
By that logic, a 160-pound man should consume around 160 grams of protein a day—the amount he'd get from an 8-ounce chicken breast, 1 cup of cottage cheese, a roast-beef sandwich, two eggs, a glass of milk, and 2 ounces of peanuts.) If you don't eat meat for ethical or religious reasons, don't worry — you can count on other sources, too. Soy, almonds, lentils, spinach, peas, and beans are packed with protein.
However, not all proteins are created equal in the muscle building stakes. Always remember the better the quality (biological value) of protein consumed, the more of it will be used for muscle building. To maximise muscle growth, stick to high-quality proteins, such as whey, milk, eggs, fish or lean meats. However, combining lower quality or incomplete protein from plant-based sources, such as nuts and beans, can still be a valuable protein source for muscle building.
Supplementation of a loading phase of creatine has been noted to augment the increase in RBC levels of superoxide dismutase (SOD) from exercise, when measured immediately after, by 8.1%, but control groups increased to match within an hour. Glutathione (normally decreases with exercise) and catalase (increases) were both unaffected, and elsewhere in vitro red blood cells incubated with 3mM of creatine (within the supplemental range) is able to improve filterability (a measure of cell rheology, or fluid structure of the cell) when RBC creatine was increased by 12.3% to reach 554µM. This was thought to be due to reduced oxidative stress (assessed via MDA) in the red blood cells, which in the presence of 1-5mM creatine was progressively reduced by 20-41%.
Even if you have a schedule that allows for a 5-day workout split, many people (I’d even call it the majority) simply don’t have the recovery capacity needed to make that work. This could be due to genetics, age, injury history, various lifestyle factors (sleep, stress, etc.) and more. In these cases, better results would be seen with 3-4 workouts per week instead.
If you want to take creatine as a supplement for bigger and stronger muscles, then the standard protocol is to have a “loading period” where you significantly increase your creatine intake for a few days or weeks. “This can prime your muscles to increase the amount of creatine that they ‘hold,’” explains Bates. “During the loading period, you generally take 5 g of creatine four times per day. After the loading period, you decrease the amount of creatine you take to a ‘maintenance’ level of 3 to 5 g per day.” (That’s also the recommendation from the International Society of Sports Nutrition.)

Weight training also requires the use of 'good form', performing the movements with the appropriate muscle group, and not transferring the weight to different body parts in order to move greater weight (called 'cheating'). Failure to use good form during a training set can result in injury or a failure to meet training goals; since the desired muscle group is not challenged sufficiently, the threshold of overload is never reached and the muscle does not gain in strength. At a particularly advanced level; however, "cheating" can be used to break through strength plateaus and encourage neurological and muscular adaptation.
One pilot study using 150mg/kg creatine monohydrate for a five day loading phase followed by maintenance (60mg/kg) for the remainder of the five weeks noted that supplementation was associated with fewer muscle symptoms and complaints alongside improved muscular function, yet a later trial trying to replicate the obsevations using 150mg/kg daily for five weeks noted the opposite, that creatine supplementation exacerbated symptoms.
