One case study on a subject with a methylentetrahydrofolate reductase (MTHFR) 677TT homozygote, a relatively common genetic mutation known as “mild MTHFR deficiency,” which causes mild homocysteinemia, has seen benefits due to creatine supplementation where homocysteine was approximately halved (49% reduction) while CT heterozygotes and CC homozygotes (n=9) were unaffected. Additionally, one rat study suggested a possible role for creatine in reducing homocysteine levels in a model of high uric acid levels (model for end stage renal disease) but this was not replicated when investigated in humans.
These complete proteins include all of the essential amino acids that the body cannot produce itself. Different proteins, such as whey and casein, egg and soy have different absorption rates. Whether you should favor one over another for muscle building is still a subject of popular and scientific debate, although whey protein isolate, a more rapidly absorbed protein, has some support from various scientific studies. For protein powders, assess the value by checking out the protein listed on the label. Combined with resistance training, sufficient protein consumption along with an appropriate diet can lead to increased muscle and reduced body fat. You should read more about The Bodybuilding Diet for supplement timing issues before and after training.
Once training is resumed under these conditions, there may be little in the way of caloric support to ensure that protein synthesis and muscle growth occurs. Muscle may even begin to cannibalize itself as the body enters into a catabolic state. Even with the best of diets this can sometimes happen if training demands override the nutritional balance or imbalance.
Co-ingesting creatine with caffeine partially negated the benefits of creatine supplementation (at 5mg/kg bodyweight) during the loading phase in one study. The exact mechanism responsible for this effect is not known, but might be related to opposing actions on muscle contraction time. However, another study in trained men found that co-ingestion of 300mg caffeine per day during creatine loading at 20g per day (split into 4 doses) had no effect on bench press 1RM, time to fatigue, or sprinting ability. However, this study also found that creatine alone or when combined with caffeine had no effect on any of these parameters over placebo, either. Thus, the study may have been underpowered or done in too short a time frame (the test was done after only 5 days of loading) to observe any possible effects.
Creatine is classified as a "dietary supplement" under the 1994 Dietary Supplement Health and Education Act and is available without a prescription. Creatine is not subjected to FDA testing, and the purity and hygienic condition of commercial creatine products may be questionable . A 1998 FDA report lists 32 adverse creatine-associated events that had been reported to FDA. These include seizure, vomiting, diarrhea, anxiety, myopathy, cardiac arrhythmia, deep vein thromboses and death. However, there is no certainty that a reported adverse event can be attributed to a particular product . A recent survey of 28 male baseball players and 24 male football players, ages 18 to 23, found that 16 (31%) experienced diarrhea, 13 (25%) experienced muscle cramps, 7 (13%) reported unwanted weight gain, 7 (13%) reported dehydration, and 12 reported various other adverse effects .
Kidney damage (from anything) will cause high levels of creatinine in blood, and creatine can also increase blood creatinine levels in a manner that is not due to damaging the kidneys. This results in a false positive when trying to diagnose kidney damange when the subject also supplements creatine, and does not signify any actual damage to the kidneys.
If you have been training properly for at least three years, you’ll find that advanced pump-enhancing techniques like rest-pause sets, drop sets, and some of the other old-school bodybuilding techniques you’ve no doubt heard of can be effective when used sparingly. Just be sure not to overdo the use of them. And never get away from the most important rule: setting PR’s to get stronger.
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.
Terry follows the old-school bodybuilding mentality of isolating each muscle group (back, shoulders, chest, legs and arms) on a five-day cycle. If he’s trying to grow a certain muscle group, he’ll introduce a second workout on the sixth day. Each of Terry’s workouts lasts between 60 and 90 minutes – “any longer and you're either not pushing yourself hard enough or you're talking too much” – and he makes the most of each session by targeting different parts of each muscle.
If you have hit a plateau, a good supplement could be all you need to pull yourself out of a slump and make the progress you want to be making. Creatine is widely known as the most effective sports supplement. Scientific studies have proven that creatine maximizes ATP production which is responsible for energy in your body. Essentially, creatine will give you more energy to allow you to do the things that will make you stronger.
Yes, you can pack on size while only doing bodyweight exercises – I did it while traveling the world – and gymnasts train mostly with bodyweight movements. However, this can feel like playing Halo on Legendary difficulty. It can be done, but damn it can be challenging – especially for lower body movements. If your sole goal is to get bigger as fast as possible, access to a barbell for squats and deadlift is almost a requirement.
Heath suggests incorporating dropsets into your training routine by immediately decreasing the weight and repping out again to failure. “Dropsets overload the muscle with shorter rest periods and increasing volume which you need to grow,” says Heath. “That overload improves your body’s abilities to utilize more nutrients, natural growth hormone, and natural testosterone into those areas and makes the supplements you take more effective.” Heath’s favorite way to do dropsets is on a pin-loaded machine since it’s faster to switch weights.
The first open label trial on ALS failed to significantly alter lung function as assessed by FEV (when comparing the rate of decline pretreatment relative to treatment). Creatine has elsewhere failed to benefit lung function at 5g daily for months relative to control and failed to significantly attenuate the rate of lung function deterioration over 16 months at 10g daily and 5g daily over nine months.
Carbohydrates provide quick energy in an anaerobic environment (high-intensity exercise), while fats provide sustained energy during periods of high oxygen availability (low-intensity exercise or rest). The breakdown of carbohydrates, fats, and ketones produces ATP (adenosine triphosphate). When cells use ATP for energy, this molecule is converted into adenosine diphosphate (ADP) and adenosine monophosphate (AMP). Creatine exists in cells to donate a phosphate group (energy) to ADP, turning this molecule back into ATP.
Exercise is highly effective in increasing your lean body mass, which is essentially muscle. In a study published in 2012, progressive resistance training helped men ages 50 to 83 gain an average of 2.4 pounds of lean body mass over an average of 20.5 weeks. Progressive resistance training involves performing weight bearing exercises. In addition, you must slowly increase the challenge of the exercise over time by increasing the weight, reps and/or sets. Studies show that either increasing reps or weight amount will work. So, if you don’t want to lift more weight, you can just do more reps and still build muscle.
McArdle’s disease is a myopathy associated with impaired glucose release from glycogen and impairments in muscle function at times when glucose would be the primary energy substrate. Creatine is thought to be therapeutic, but has shown differing effects in the two trials so far (both benefit and worsening of symptoms) for currently unknown reasons.
Creatine is used and researched in a clinical setting to investigate various pathologies or disorders such as myopathies [3,4] and is also used as an ergogenic aid for improving health and sports performance in athletes . As an oral supplement, the most widely used and researched form is creatine monohydrate (CM). When orally ingested, CM has shown to improve exercise performance and increase fat free mass [5-9].
Of course, cardio is an important part of fitness too, but the benefits of strength training are major. Strength training helps build muscle, and lean muscle is better at burning calories when the body is at rest, which is important whether you're trying to lose weight or maintain it. It also helps strengthens joints and bones, avoid injury, improve your muscular endurance, and will help you give it your all during your other workouts, whether that means setting a new PR if you're a runner or pushing (and pulling) a little harder with your legs during your favorite indoor cycling class.

According to the abstract, in the stratified analyses by forms of aerobic exercise, weekly resistance exercise of 1 time or 1-59 minutes was associated with lower risks of total cardiovascular events and cardiovascular disease, regardless of meeting the aerobic exercise guidelines. The analysis showed that resistance training reduced the risk of cardiovascular events in 2 ways: training had a direct association with cardiovascular risk, and resistance training indirectly lowered cardiovascular risk by decreasing body mass index.
Honestly, I did a lot of research on this one, because I wanted to find a single group of people who should not strength train. I even found studies on how strength training can be beneficial for paraplegics. Not to mention it can be safe for children, adolescents, and pregnant women. Obviously, you should take a break from strength training if you’re injured, and always check with your doctor before you start any sort of strength training program, but it’s natural for us, as humans, to move around and carry things.
It is regularly reported that creatine supplementation, when combined with heavy resistance training leads to enhanced physical performance, fat free mass, and muscle morphology [18-22]. A 2003 meta analysis  showed individuals ingesting creatine, combined with resistance training, obtain on average +8% and +14% more performance on maximum (1RM) or endurance strength (maximal repetitions at a given percent of 1RM) respectively than the placebo groups. However, contradicting studies have reported no effects of creatine supplementation on strength performance. Jakobi et al  found no effects of a short term creatine loading protocol upon isometric elbow flexion force, muscle activation, and recovery process. However, this study did not clearly state if creatine supplementation was administered concurrent with resistance training. Bemben et al  have shown no additional benefits of creatine alone or combined with whey protein for improving strength and muscle mass after a progressive 14 weeks (3 days per week) resistance training program in older men. These conflicting results can be explained by the possibility that the supplemented groups were formed by a greater amount of non-responders or even because creatine supplementation was administered on the training days only (3 times a week). This strategy has not been adequately tested as effective in middle aged and older men for maintaining post loading elevated creatine stores .
In regard to practical interventions, concurrent glycogen loading has been noted to increase creatine stores by 37-46% regardless of whether the tissue was exercised prior to loading phase. It is important to note, however, that creatine levels in response to the creatine loading protocol were compared in one glycogen-depleted leg to the contralateral control leg, which was not exercised. This does not rule out a possible systemic exercise-driven increase in creatine uptake, and the increase in creatine noted above was larger than typically seen with a loading protocol (usually in the 20-25% range). Consistent with an exercise-effect, others have reported that exercise itself increases creatine uptake into muscle, reporting 68% greater creatine uptake in an exercised limb, relative to 14% without exercise.
Creatine is not an essential nutrient as it is naturally produced in the human body from the amino acids glycine and arginine, with an additional requirement for methionine to catalyze the transformation of guanidinoacetate to creatine. In the first step of the biosynthesis these two amino acids are combined by the enzyme arginine:glycine amidinotransferase (AGAT, EC:18.104.22.168) to form guanidinoacetate, which is then methylated by guanidinoacetate N-methyltransferase (GAMT, EC:22.214.171.124), using S-adenosyl methionine as the methyl donor. Creatine itself can be phosphorylated by creatine kinase to form phosphocreatine, which is used as an energy buffer in skeletal muscles and the brain.
It’s perhaps best known for the aesthetic benefits. Creatine increases muscle size relatively quickly and while that’s in part due to an increase in muscle water content — a good thing, since it means we’re better hydrated — it does indeed appear to lead to actual hypertrophy over time. And bigger muscles aren’t just aesthetic: larger muscles can improve work capacity, explosiveness, fat oxidation, injury resilience, and recovery.
I'm 6'1" 175 pounds 27 years old. I would like to increase my general muscle mass and reduce my stomach fat. I would consider myself and ectomorph (hard gainer) as I have never really developed much muscle while I've always been very active in sports and periodic weight training. Over the past year I lost about 30 pounds (nearly all fat) by reducing my caloric intake effectively and regular whole body exercises. I was on my way to my ideal body composition until I became a bike courier. I've been a bike messenger for 9 months and recently my stomach fat has started to return. I'm riding 50+ miles each weekday riding for 9 hours a day. How many calories should I be eating? I've tried everywhere between 2400-3,500 cal/day. Is it possible for me to be eating too few calories while still accumulating stomach fat? Is it realistic for me to be able to maintain or even build muscle mass in this scenario? Please help, thanks.
“Don't get set into one form, adapt it and build your own, and let it grow. Be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot. Now water can flow or it can crash. Be water, my friend.” Bruce Lee
The lower the rep range (and therefore the higher the intensity and the heavier the weight), the more rest there should be between sets. So most of the time, exercises being done in the 5-8 rep range need longer rest periods than exercises being done in the 8-10 rep range, which need longer rest periods than exercises being done in the 10-15 rep range.
After your standard whey protein powder, creatine may be the most popular sports supplement on Earth, and with good reason. A lot of supplements out there have a few promising studies suggesting they may improve some aspect of performance. Creatine has hundreds of them, and study after study has shown that among most people (a small percentage of are non-responders) it can have a significant effect on several areas of performance.

Do standard/oblique crunches. Lie down on a mat and position both arms behind your head without locking the hands. Bend your knees so that your feet are flat on the ground. Pushing the small of your back into the ground, slowly roll your shoulders off the ground only a couple of inches (not to a full sitting position). Don't use your momentum to help you up; use slow, regulated movements. Repeat 3 x 20.
When assessing the antioxidant effects of creatine, it does not appear to sequester superoxide and may not be a direct antioxidant. Additionally, creatine failed to protect neurons from H2O2 incubation to induce cell death via pro-oxidative means. These results are in contrast to previously recorded results suggesting creatine acts as a direct anti-oxidant.
Creatine kinase enzymes (of which there are numerous isozymes) exist in both the mitochondria and the cytosol of the cell. The four isozymes of creatine kinase include the Muscle Creatine Kinase (MCK), present in contractile muscle and cardiac muscle, and the Brain Creatine Kinase (BCK), expressed in neuron and glial cells and several other non-muscle cells. These two creatine kinases are met with Sarcolemmic Mitochondrial Creatine Kinase (sMitCK), expressed alongside MCK, and the ubiquitous Mitochondrial Creatine Kinase (uMitCK), which is expressed alongside BCK everywhere else.
How to maximize its effects: Take 20 grams of whey protein powder in the 30 minutes before working out, and take 40 grams within 60 minutes after training. Also consider taking 20-40 grams of whey immediately upon waking every morning to kick-start muscle growth. Your best bet is to choose a whey powder that contains whey protein hydrolysates (whey protein broken down into smaller fragments for faster digestion) or whey protein isolate.
