With creatine supplements, you can top that up to percent, which will give you a little more energy for each burst from the anaerobic alactic system. A few studies have tested this idea. For example, a study from Australian Catholic University put cyclists through K time trials punctuated by a series of 1K and 4K sprints.
That makes creatine an easier sell for non-weight-bearing sports like cycling and swimming than for running. Still, the Australian cycling study mentioned above finished with an uphill ride to exhaustion to see if the negative effects of weight gain would outweigh the positive effects of creatine, and found that it was a wash.
But it turns out that creatine has a huge range of other possible benefits, perhaps not surprisingly given that it plays such an important role in the energy supply of cells throughout the body. Taking creatine along with carbohydrate seems to enhance glycogen storage in the muscles.
The extra water retention, despite its added weight, may help performance in heat. Oh, and it may also help buffer rising blood pH, reduce neuromuscular fatigue, counteract inflammation, and speed up recovery. And did I mention the potential health benefits for bone strength, concussion, degenerative brain conditions, heart disease, and more?
At this point, your alarm bells may be ringing. The authors are avowed fans of supplements in general and creatine in particular. Forbes, the lead author, goes by the handle of Dr. My own take is that, at least for now, we should ignore most of the secondary claims about heat stress and inflammation and brain health and so on.
None have been shown to outperform the cheapest and most basic version, creatine monohydrate. You can also skip the loading phase and just stick to 3 to 5 grams, in which case it will take about four weeks to max out. This latter approach may be less likely to cause water-related weight gain.
You can cycle on and off creatine depending on your training or racing goals. right afterideally with some carbohydrates. A separate stream of creatine research these days focuses on its potential benefits in combination with resistance training for helping older adults slow down the inevitable muscle loss that accompanies aging.

| The Pros and Cons of Creatine Monohydrate for Endurance Athletes | TrainingPeaks | Yes, there are some rare conditions of creatine deficiency that may require additional creatine through diet or over-the-counter medications. No, creatine is not prohibited. Although creatine can have a small effect on performance, the effects are not guaranteed and the specific training program remains most influential. To date, no long-term health risks have been reported with extended use up to four years , however, some people report short-term water retention and decreased urinary volume, resulting in bloating and temporary weight gain 2 -5 pounds. In addition, a potentially increased risk of compartment syndrome and muscle cramps has been reported. In terms of anti-doping risks, athletes should be careful about using creatine supplements because all supplements come with some level of risk due to the post-market regulatory process, which means that products contaminated with banned substances make it onto store shelves. org or call , option 2.

Creatine supplementation: what all athletes need to know Supplements by Andrew Hamilton. Creatine methylguanidine-acetic acid was discovered in , but athletes have been taking it - in hopes of improving their performances - for only the last 10 years. Over that time period, a scientific consensus has emerged that creatine supplementation can indeed increase muscular strength and power and improve performances in relatively short-duration, high-intensity activities. The potential benefits of creatine supplementation for longer-duration, lower-intensity exertion i. To get a better insight into this debate, you should understand that muscle cells use creatine to form creatine phosphate, a high-energy compound which can be used to rapidly synthesize ATP, the 'energy currency' utilized by all cells in the human body. Whenever a nerve cell fires, a muscle fibre contracts, or a kidney cell actively filters some urine, ATP 'pays the bills' i. Note that the advantage associated with creatine supplementation became smaller as the duration of the work interval increased. This is not terribly surprising. As work-interval duration increases, the relative amount of the energy which is needed to complete the interval which is actually coming from creatine phosphate decreases, as the creation of ATP from the breakdown of carbohydrate rather than from the transfer of a phosphate group from creatine phosphate becomes much more important. As work-interval duration increases, exercise intensity also declines, which means that creatine phosphate's role as a buffer becomes less important. On average, your body can produce around grams of creatine per day. As for the creatine content of meat and fish, the amount is pretty small. In fact, you would need to consume approximately 1 pound 16 ounces of these foods to obtain grams of creatine. From there, it can be used as a quick energy source for short bursts of high-intensity activities as well as replenish your ATP stores the primary energy for cells. This is where creatine shines, providing that fast fuel and contributing to ATP storage. For this purpose , creatine is the safest and most effective nutritional supplement currently available. When choosing a creatine supplement, know that there are several types. The most widely used and researched is creatine monohydrate, but other forms include creatine ethyl ester, buffered creatine, and creatine hydrochloride creatine hcl. Creatine monohydrate: This is a white, crystalline powder that is quickly absorbed and transferred from your blood to your muscles to be used for energy. It typically has no odor or flavor. Creatine ethyl ester: This form has been chemically modified with an ethyl group in order to boost its bioavailability. While it claims to be more effective than other forms of creatine, the evidence is mixed. Buffered creatine: Also called Kre-Alkalyn, this type of creatine has had its pH adjusted to be less acidic compared to other forms, particularly creatine monohydrate. Physiol Genomics.

Effects of creatine supplementation on predominantly anaerobic exercise Creatine has demonstrated neuromuscular performance enhancing properties on short duration, predominantly anaerobic, intermittent exercises. Effects of creatine supplementation on skeletal muscle hypertrophy Cribb et al [ 29 ] observed greater improvements on 1RM, lean body mass, fiber cross sectional area and contractile protein in trained young males when resistance training was combined with a multi-nutrient supplement containing 0. Effects of creatine supplementation on predominantly aerobic exercise Although creatine supplementation has been shown to be more effective on predominantly anaerobic intermittent exercise, there is some evidence of its positive effects on endurance activities. Effects of creatine supplementation on glycogen stores It is suggested [ 16 , 37 ] that another mechanism for the effect of creatine could be enhanced muscle glycogen accumulation and GLUT4 expression, when creatine supplementation is combined with a glycogen depleting exercise. Effects of creatine ingestion to improve recovery from injury, muscle damage and oxidative stress induced by exercise Creatine supplementation may also be of benefit to injured athletes. Documented effects of creatine supplementation for health and clinical setting Neurological and cognitive function has also been shown to be improved by creatine supplementation [ 47 , 48 ]. Responders vs. non-responders 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. Commercially available forms of creatine 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 in combination with other supplements Although creatine can be bought commercially as a standalone product it is often found in combination with other nutrients. Safety and side effects of creatine supplementation There have been a few reported renal health disorders associated with creatine supplementation [ 73 , 74 ]. Conclusion and practical recommendations The above review indicates that creatine supplementation has positive effects on: Amplifying the effects of resistance training for enhancing strength and hypertrophy [ 5 , 22 , 28 ].

Creatine does precisely what it says on the tin Editor's Picks Endurance and strength: YOU have the best of both worlds.
Creatine is also available as a supplement and is often used by athletes during a specific period of training. Most supplementation protocols consist of a loading phase lasting approximately one week, followed by a maintenance phase.
Consuming creatine, either in foods or supplements, can increase muscle creatine stores. However, not all athletes benefit from creatine since the training program itself remains the key component of success.
Yes, there are some rare conditions of creatine deficiency that may require additional creatine through diet or over-the-counter medications. No, creatine is not prohibited. Although creatine can have a small effect on performance, the effects are not guaranteed and the specific training program remains most influential.
To date, no long-term health risks have been reported with extended use up to four years , however, some people report short-term water retention and decreased urinary volume, resulting in bloating and temporary weight gain 2 -5 pounds.
In addition, a potentially increased risk of compartment syndrome and muscle cramps has been reported. In terms of anti-doping risks, athletes should be careful about using creatine supplements because all supplements come with some level of risk due to the post-market regulatory process, which means that products contaminated with banned substances make it onto store shelves.

Creatine may be of benefit in other modes of exercise such as high-intensity sprints or endurance training. However, it appears that the effects of creatine diminish as the length of time spent exercising increases.
