When assessing type I muscle (slow twitch) against type II muscles (fast twitch) in response to creatine supplementation, it seems that glycogen accumulation may only occur in the latter as assessed in rats,[359] where the soleus muscle is a model for slow twitch muscle fibers and the gastrocnemius is a model for fast twitch. This is similar to human creatine distribution, which seems to accumulate in type II muscles rather than type I.[367]

Whey, the liquid remaining after milk has been curdled and strained, is rapidly digested and absorbed and has a remarkable ability to stimulate muscle protein synthesis (Hayes & Cribb, 2008). Whey is available in three varieties — whey protein powder, whey protein concentrate, whey protein isolate — and all provide high levels of the essential and branched chain amino acids, vitamins and minerals.

If you are underweight or have a naturally scrawny build, you may struggle to gain weight, let alone muscle mass, no matter what you do. Eating at all hours of the day and night can be exhausting and require frequent trips to the grocery store. Unless you are overweight, you likely need to create a caloric surplus in order to gain muscle. With a weight gainer powder, you can supplement a healthy diet with the additional calories you need to gain weight in muscle.
Co-ingesting creatine with caffeine partially negated the benefits of creatine supplementation (at 5mg/kg bodyweight) during the loading phase in one study.[590] The exact mechanism responsible for this effect is not known, but might be related to opposing actions on muscle contraction time.[591] 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.[592] 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.[592]

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.

Heart Failure is one of the single most common complications that face many people today. When a heart ages, the cells collect a yellow-brown layer which is waste and can lead to heart complications. This process is known as lipofuscin, or “aging pigment” which leads to death opposed to someone who can delay that as far as possible. [3] In mice, a study was performed where two groups of mice who had lipofuscin underwent different experiments, one group received creatine supplementation, and one group did not receive supplementation. What they found was that the mice who supplemented creatine lived 9% longer than the ones who did not receive creatine. 9% translated into human years results in almost 7 years, which could suggest that if you suffer from this deterioration, creatine supplementation could potentially increase your longevity by 7 years. [3]
Bodybuilders often split their food intake for the day into 5 to 7 meals of roughly equal nutritional content and attempt to eat at regular intervals (e.g. every 2 to 3 hours). This method can serve two purposes: to limit overindulging in the cutting phase, and to physically allow for the consumption of large volumes of food during the bulking phase. Contrary to popular belief, eating more frequently does not increase basal metabolic rate when compared to the traditional 3 meals a day. While food does have a metabolic cost to digest, absorb, and store, called the thermic effect of food, it depends on the quantity and type of food, not how the food is spread across the meals of the day. Well-controlled studies using whole-body calorimetry and doubly labeled water have demonstrated that there is no metabolic advantage to eating more frequently.[38][39][40]
Creatine supplementation appears to attenuate decreases in GLUT4 expression seen with immobility and may increase GLUT4 expression during exercise. While it seems capable of increasing GLUT4 during resting conditions, it has failed to reach significance, suggesting that creatine supplementation works best with some stimuli associated with exercise.
Perform the workout three days a week for four weeks, resting at least one day between each session. On the weight exercises, choose a load that allows you to complete a few more reps than the prescribed number (you may need to adjust this load between sets as you discover your strength levels). For instance, if an exercise calls for 12 reps, choose a load that you estimate you can perform 15 reps with before having to stop (but complete only 12).
A commercially available pre-workout formula comprised of 2.05 g of caffeine, taurine and glucuronolactone, 7.9 g of L-leucine, L-valine, L-arginine and L-glutamine, 5 g of di-creatine citrate and 2.5 g of β-alanine mixed with 500 ml of water taken 10 minutes prior to exercise has been shown to enhance time to exhaustion during moderate intensity endurance exercise and to increase feelings of focus, energy and reduce subjective feelings of fatigue before and during endurance exercise due to a synergistic effect of the before mentioned ingredients [72]. The role of creatine in this formulation is to provide a neuroprotective function by enhancing the energy metabolism in the brain tissue, promoting antioxidant activities, improving cerebral vasculation and protecting the brain from hyperosmotic shock by acting as a brain cell osmolyte. Creatine can provide other neuroprotective benefits through stabilisation of mitochondrial membranes, stimulation of glutamate uptake into synaptic vesicles and balance of intracellular calcium homeostasis [72].
You don’t have to, but you can. The typical creatine dose is 5 grams once or twice per day, but it’s sometimes suggested that one should “load” creatine by taking 20 to 25 grams per day for the first week of usage. This is then followed with 3 to 4 weeks of 5 grams per day, then a break for a week or two, then repeat. This may bring about more acute increases in strength and muscle size — creatine will “work” more quickly, in other words — but it’s not necessary.
Gain mass: One of the most popular reasons for people to take body building supplements is to gain weight and that is why protein powder is much sought after. Protein is the building block of muscles and therefore, bodybuilders use protein powder to help repair muscles, speed recoveries and preserve muscle mass. They usually consume 1 to 2 grams of protein per pound of body weight every day. 

Vegetarians and other people who have lower total creatine levels when they start taking creatine supplements seem to get more benefit than people who start with a higher level of creatine. Skeletal muscle will only hold a certain amount of creatine; adding more won't raise levels any more. This "saturation point" is usually reached within the first few days of taking a "loading dose."
Creatine monohydrate is the most common form of creatine, and if not otherwise mentioned is the default form of creatine used in most studies on creatine.[64] It has fairly decent intestinal absorption[65][12] (covered more in depth in the pharmacology section) and is the standard form or “reference” form of creatine, which all other variants are pitted against.
Creatine, the amino acid, naturally helps your body produce more adenosine triphosphate, or ATP, a small molecule that’s actually your body's primary energy source. But research shows that your body is only capable of storing enough ATP for 8 to 10 seconds of high-intensity exercise — and after that, it needs to produce new ATP for you to continue. (9)

The neuroprotective effects of creatine appear to exist in regard to dopamine biosynthesis, and the suppression of dopamine synthesis seen with some neurological toxins appears to be partially attenuated with dietary intake of creatine. The protective effect is weak to moderate in animal research, but appears to be additive with anti-inflammatories.

Legion’s Recharge is a good pick for muscle growth. Besides the creatine itself, it contains a hefty 2.1 grams of l-carnitine l-tartrate, which has solid links with improving muscle repair in addition to increasing focus during workouts. It’s also delicious, naturally sweetened, and it contains ingredients that may improve insulin sensitivity and help the body to better utilize carbs for recovery.
Eat 1.5–3 grams of carbs per pound of your body weight. As with fat, this amount can vary greatly, depending on your personal needs and preferences, so consider these numbers only a starting point. If you’re very skinny and feel that you handle carbs well (i.e. you can eat a lot of them without getting fat), go ahead and eat according to the higher end of the spectrum. The same applies if you’re desperate to gain weight—you should increase your carb intake. If you’re prone to weight gain or feel lethargic on higher carbs, you should eat fewer of them. Again, see our keto guide for more details and options.

When you’re planning your high-protein meals, 20 grams of protein is the optimal amount generally accepted for muscle growth. Research has found that the body doesn’t use much more than 20 grams for muscle-building at any one sitting. Around 80 grams of protein per day (or, four meals containing 20-grams of protein each) is about right for most people.
Syrotuik and Bell [57] investigated the physical characteristics of responder and non-responder subjects to creatine supplementation in recreationally resistance trained men with no history of CM usage. The supplement group was asked to ingest a loading dosage of 0.3 g/kg/d for 5 days. The physiological characteristics of responders were classified using Greenhaff et al [58] criterion of >20 mmol/kg dry weight increase in total intramuscular creatine and phosphocreatine and non responders as <10 mmol/kg dry weight increase, a third group labeled quasi responders were also used to classify participants who fell in between the previously mentioned groups (10-20 mmol/kg dry weight). Overall, the supplemented group showed a mean increase in total resting muscle creatine and phosphocreatine of 14.5% (from 111.12 ± 8.87 mmol/kg dry weight to 127.30 ± 9.69 mmol/kg dry weight) whilst the placebo group remained relatively unaffected (from 115.70 ± 14.99 mmol/kg dry weight to 111.74 ± 12.95 mmol/kg dry weight). However when looking at individual cases from the creatine group the results showed a variance in response. From the 11 males in the supplemented group, 3 participants were responders (mean increase of 29.5 mmol/kg dry weight or 27%), 5 quasi responders (mean increase of 14.9 mmol/kg dry weight or 13.6%) and 3 non-responders (mean increase of 5.1 mmol/kg dry weight or 4.8%). Using muscle biopsies of the vastus lateralis, a descending trend for groups and mean percentage fiber type was observed. Responders showed the greatest percentage of type II fibers followed by quasi responders and non-responders. The responder and quasi responder groups had an initial larger cross sectional area for type I, type IIa and type IIx fibers. The responder group also had the greatest mean increase in the cross sectional area of all the muscle fiber types measured (type I, type IIa and type IIx increased 320, 971 and 840 μm2 respectively) and non-responders the least (type I, type IIa and type IIx increased 60, 46 and 78 μm2 respectively). There was evidence of a descending trend for responders to have the highest percentage of type II fibers; furthermore, responders and quasi responders possessed the largest initial cross sectional area of type I, IIa and IIx fibers. Responders were seen to have the lowest initial levels of creatine and phosphocreatine. This has also been observed in a previous study [17] which found that subjects whose creatine levels were around 150 mmol/Kg dry mass did not have any increments in their creatine saturation due to creatine supplementation, neither did they experience any increases of creatine uptake, phosphocreatine resynthesis and performance. This would indicate a limit maximum size of the creatine pool.
In otherwise healthy adults subject to leg immobilization for two weeks while taking 20g creatine daily during immobilization and then 5g daily during eight weeks of rehabilitation, it was noted that the creatine group failed to reduce atrophy during the immobilization (10% reduction in cross sectional area and 22-25% reduction in force output) despite preventing a decrease in phosphocreatine, yet experienced a significantly enhanced rate of regrowth and power recovery.[358] A similarly structured and dosed study has also noted greater expression of skeletal muscle, GLUT4 expression, and a 12% increase in muscle phosphocreatine content.[330]

How to Take It: Take your gainer at any time of day as your objective is to reach overall calorie intake goals. Ideally, instead of using them as a meal substitute, you’ll use your gainer as a snack between high-calorie, healthy, balanced meals. If you plan on taking protein powder for muscle growth in addition to gainers, make sure you add up all of your dietary protein intakes to make sure it’s worth the investment of taking both. You might be able to skip the plain protein powders.

It’s an amazing feeling when you graduate from lifting 10-pounders to 15-pounders. “Over time, you get better at something you’re doing, and you develop a sense of mastery and feeling that you’re getting stronger,” explains James Whitworth, a doctoral research fellow in the Biobehavioral Resistance Training Lab at Columbia’s Teachers College in New York City. “It helps your confidence, and that gives you a boost in self-esteem.”

Free weights include dumbbells, barbells, medicine balls, sandbells, and kettlebells. Unlike weight machines, they do not constrain users to specific, fixed movements, and therefore require more effort from the individual's stabilizer muscles. It is often argued that free weight exercises are superior for precisely this reason. For example, they are recommended for golf players, since golf is a unilateral exercise that can break body balances, requiring exercises to keep the balance in muscles.[27]

Other areas of research include therapeutic uses of creatine to help patients with muscle wasting caused by disease states such as muscular dystrophy and amyotrophic lateral sclerosis (ALS). Small-scale preliminary studies show some gains in strength may be possible for these patients, which could improve their quality of life. One study of 81 patients with various neurologic diseases found that giving 10 g/day of creatine for five days, followed by 5 grams for another week, increases their muscle strength by about 10% [20]. Large-scale studies should be done before recommendations are made to such patients.
Heart Failure is one of the single most common complications that face many people today. When a heart ages, the cells collect a yellow-brown layer which is waste and can lead to heart complications. This process is known as lipofuscin, or “aging pigment” which leads to death opposed to someone who can delay that as far as possible.

Activation of NMDA receptors is known to stimulate Na+,K+-ATPase activity[218] secondary to calcineurin,[219] which which has been confirmed with creatine in hippocampal cells (0.1-1mM trended, but 10mM was significant). This is blocked by NMDA antagonists.[220] This increase in Na+,K+-ATPase activity is also attenauted with activation of either PKC or PKA,[220] which are antagonistic with calcineurin.[219][221]

Contrast loading is the alternation of heavy and light loads. Considered as sets, the heavy load is performed at about 85-95% 1 repetition max; the light load should be considerably lighter at about 30-60% 1RM. Both sets should be performed fast with the lighter set being performed as fast as possible. The joints should not be locked as this inhibits muscle fibre recruitment and reduces the speed at which the exercise can be performed. The lighter set may be a loaded plyometric exercise such as loaded squat jumps or jumps with a trap bar.
There are several different available forms of creatine: creatine anhydrous which is creatine with the water molecule removed in order to increase the concentration of creatine to a greater amount than that found in CM. Creatine has been manufactured in salt form: creatine pyruvate, creatine citrate, creatine malate, creatine phosphate, magnesium creatine, creatine oroate, Kre Alkalyn (creatine with baking soda). Creatine can also be manufactured in an ester form. Creatine ethyl ester (hydrochloride) is an example of this, as is creatine gluconate which is creatine bound to glucose. Another form is creatine effervescent which is creatine citrate or CM with citric acid and bicarbonate. The citric acid and bicarbonate react to produce an effervescent effect. When mixed with water the creatine separates from its carrier leaving a neutrally charged creatine, allowing it to dissolve to a higher degree in water. Manufacturers claim that creatine effervescent has a longer and more stable life in solution. When di-creatine citrate effervescent was studied [59] for stability in solution it was found that the di-creatine citrate dissociates to citric acid and creatine in aqueous solutions which in turn forms CM and eventually crystallises out of the solution due to its low solubility. Some of the creatine may also convert to creatinine.
Collectively the above investigations indicate that creatine supplementation can be an effective strategy to maintain total creatine pool during a rehabilitation period after injury as well as to attenuate muscle damage induced by a prolonged endurance training session. In addition, it seems that creatine can act as an effective antioxidant agent after more intense resistance training sessions.
