Guest guest Posted February 14, 2008 Report Share Posted February 14, 2008 I don't know about studies but I bet if you talk to power lifters who have used creatine at one time or another they have experienced extreme muscle cramps while taking creatine. I don't know who these studies were done on but I'm going to tell you that I have never had muscle cramps while not taking creatine and I have been literally brought to my knees while taking it. I can think of three individual meets where I was doing something like tying my shoes between lifts when muscle cramps so severe in pain took my breath away and I'm no weakling when it comes to pain. Of late I have used the esterfied creatine and not experienced this but I'm here to tell you that creatine does cause muscle cramps when coupled with dehydration. Would that keep me from using creatine, heck no. Muscle cramps to my knowledge are not serious and they are usually short in duration so big deal. Just my thoughts and experience.

Casler writes: Hi Eddie, My experience has been the same. That is not to say I am negative on the use of Creatine, since I highly recommend and use it. But, I get occasional (and some are mind blowing) cramps in my hands, calves, hams, various abs, intercostals, Platysma Sternocleido, and other neck muscles that are 100% related to when, and or, if I use creatine. While this may be due to dehydration, it is not due to not drinking fluids, for I drink at least a gallon of fluids daily. In fact, I drink at least 32oz of water and lemon juice just before going to bed each night (just call me IRON BLADDER) thinking that it might have a longer hydrating window. I think that everyone knows that creatine " requires " more water, due to its " cellular hydrating effects " . I might suspect that some, and I guess I am one, may not have the body chemistry (cellular pump mechanism) to osmotically add enough fluid to each cell as the intercellular concentration requires. Either that or there may be some type of trigger mechanism, but to be sure, I get cramps (which I have never had in over 45 years) that directly correspond to my use of, or not using creatine, and training a bodypart. That is, it generally happens post training 1-24 hours. There also may be an additional secondary cause, such as lack of electrolyte balance or such, but again, I take supplements that have the correct sodium, potassium, calcium etc values. And again, this is not a word against the use of creatine, since I still use it regularly, and in rather large amounts, but when I cycle off for a few days, the cramps are totally non-existent. Since Eddie, you and I are " oldsters " it may have something to do with the cells losing the ability to hydrate beyond a certain point (since dehydration is one of the elements of cellular aging) and even upping the fluid intake will not up the cellular fluid uptake, while the creatine uptake (and subsequent concentration) has increased within the cell.

Guest guest Posted February 20, 2008 Report Share Posted February 20, 2008 Hi Bill Thanks for bringing that up. In the ten + years that I have used creatine on an " on/off " basis for bodybuilding, I've never had a problem with muscle cramping, nor have any others I've known. My educated guess would tell me that there's got to be something else behind it: a mineral imbalance or deficiency. Thanks for touching on that.

Guest guest Posted February 21, 2008 Report Share Posted February 21, 2008 Hi Bill In your post you ask the question " Does it makes sense that greater intramuscular water would cause cramps? " I think it may if you look at the post by Carruthers entitled " Dehydration/Electrolyte Depletion and Cramps " in which he relates a web site that discusses the lack of scientific evidence for the electrolyte depletion model . I have tried to extract the relevant bits but it is quite long still so I have highlighted the most outstanding sentences in caps – not to shout but to make noticable. Following this I have quoted from your excerpts from you creatine study. ************ The electrolyte depletion model of muscle cramps http://scienceofsport.blogspot.com/search/label/muscle%20cramps …..Professor Schwellnus is hands down the one researcher who has consistently moved this area forward. As a sports physician he has treated many a runner with cramps, and his curiosity and what he was seeing in the medical tents lead him to challenge this paradigm that dehydration and electrolyte problems cause cramps. What he found was that this model was based on not one shred of scientific data, and instead relied heavily on anecdotal evidence. Since 1997 he has published some of the only evidence available that has even attempted to determine what actually is causing the cramps and who is prone to this condition. In a 2004 study published in the British Journal of Sports Medicine, Professor Schwellnus and his colleagues examined runners before and after the Two Oceans 56 km marathon in Cape Town. WHAT IS ALSO NOTEWORTHY FROM THIS STUDY WAS THAT THE CRAMPERS HAD AN AVERAGE LOSS OF BODY WEIGHT OF 2.9%, COMPARED TO 3.6% FOR THE NON- CRAMPING CONTROLS. IN OTHERWORDS, THE PEOPLE WHO DID NOT CRAMP LOST MORE WEIGHT THAN THE PEOPLE WHO DID. It goes further than this, because Schwellnus et al were able to measure the change in plasma volume as well - a more direct measure for what is happening to fluids. HERE, THEY FOUND THAT THE CRAMPERS ACTUALLY GAINED A SMALL AMOUNT OF 0.2% DURING THE RACE. THE NON-CRAMPING CONTROL SUBJECTS LOST 0.7%. So the sum effect of this data is that it suggests very strongly that cramping is not associated with dehydration, or with lower serum electrolyte levels, which is what we have had drilled into us for many years! The next year they published a study in Medicine and Science in Sports and Exercise, and instead of runners it was Ironman triathletes……. So the two groups were essentially the same in that the crampers did not spend longer in the course or lose more weight (a crude measure of dehydration). Yet again the crampers and the controls looked remarkably similar on paper---except as in the 2004 study the crampers again had a statistically SIGNIFICANT LOWER SODIUM concentration, and, we will repeat this, THAT SUGGESTS THEY WERE MORE HYDRATED COMPARED TO THE CONTROLS. . .YET THEY WERE CRAMPING.... ************** You then quote this from the study of creatine ************** The Effects of Creatine Loading on Thermoregulation and Intermittent Sprint Exercise Performance in a Hot Humid Environment The Journal of Strength and Conditioning Research Aug 2007 " Therefore,increases in total body water resulting from Cr supplementation may prove to be beneficial for maintaining hydration status and core tempterature in athletes training or competing in the heat.

" (The authors cite six studies to support this statement.) - p 655 ********** So you asked - does it makes sense that greater intramuscular water would cause cramps? Well given the discussion above I will ask a question which on reflection was badly asked in my previous post. Is not the increased intramuscular water resulting in a situation of hyponatremia localised in the muscle causing cramps. Is the author of the creatine paper not making a fundamentally incorrect assumption that increased hydration is better than either controlled balanced hydration or minor losses in water as this causes an increase in mineral concentration which may be beneficial. Is the creatine possibly causing the cramps through increased hydration? Best regards Nick Tatalias Johanesburg South Africa Quote Link to comment Share on other sites More sharing options...

Guest guest Posted February 24, 2008 Report Share Posted February 24, 2008 Hi Chad No I am not in school, I graduated some 18 years ago. I think the idea would be to assess whether there is a link between increased intramuscular water volume, and cramping relating to sodium deficiency. That was the hypothesis presented in the two papers. Does the absorption of creatine into tissue effect sodium, calcium or other minerals in balance how does this effect water balance. I rarely take creatine as a supplement as it didn't seem to have the wondrous effect on me that others reported, I probably eat enough red meat to meet most of my creatine needs, but if it did give me cramps I would experiement with talking salt tablets (assuming no pathology of hypertension) to see if this helped me. (Table salt contains a lot of potassium iodate, so that isn't the best tool to use for testing). Of course if the effect is localised this may not help. Some additional thoughts any comments.

Guest guest Posted February 24, 2008 Report Share Posted February 24, 2008 Hi Chad No I am not in school, I graduated some 18 years ago. I think the idea would be to assess whether there is a link between increased intramuscular water volume, and cramping relating to sodium deficiency. That was the hypothesis presented in the two papers. Does the absorption of creatine into tissue effect sodium, calcium or other minerals in balance how does this effect water balance. I rarely take creatine as a supplement as it didn't seem to have the wondrous effect on me that others reported, I probably eat enough red meat to meet most of my creatine needs, but if it did give me cramps I would experiement with talking salt tablets (assuming no pathology of hypertension) to see if this helped me. (Table salt contains a lot of potassium iodate, so that isn't the best tool to use for testing). Of course if the effect is localised this may not help. Some additional thoughts any comments.

And not surprisingly, athletes in all sports launched into its use without really knowing or considering the side effects. I'll never forget my first " exposure " to creatine, was in discussion with the fitness trainer of the Western Province professional rugby team. The trainer is a highly qualified scientist (holds a Masters degree so has a reasonably sound grasp of making inferences based on observation) and he had worked with the same group of professional players for three years before the whole team decided that they needed to use creatine! Now back then, as I said, knowledge and understanding was in relatively short supply, and I'll never forget the story he tells of the first time the players used it. They'd figured that if they ingested creatine during half-time they'd see benefits almost instantly. So during the half-time break, the players all took their mixture. He says that in the second half, 12 out of the 15 players on the field came down with cramp! Now, obviously, they'd been using creatine in the build-up to the game, and so the effect was not simply due to taking creatine at half- time. But he was absolutely convinced that the creatine had caused the cramping. He said they all went off it after that, or reduced the dosage and timing of ingestion, and the problem never happened again. For 12 out of 15 professional players to cramp would suggest something other than co-incidence! I'm not ideally positioned to say he is either right or wrong. I had a look through the scientific articles on the site, one of which says that creatine actually REDUCES cramping, the other finding no effect. My personal thought on that type of study is to interpret with caution - in science, one of the most difficult things around is establishing what we call " causality " . It's very easy to find associations, as these studies have done (Creatine use is ASSOCIATED with reduced cramping), but to actually say that A causes B is very difficult. And in this type of study in particular, there's the problem that whenever you do research, your 'presence' as the investigator alters the normal relationships and systems you're studying! In other words, those studies present very controlled settings, where the training, the diet, the use of creatine and the between training activities are meticulously controlled. That situation does not necessarily hold for your use of creatine and your training. Also, in these kinds of studies, the training benefit of creatine (that is, the groups taking creatine may develop resistance to cramping because they are better trained than the control group. This " confounding factor " might mean that the more appropriate conclusion from these studies is that " Creatine use and proper training will combine to reduce cramping during an entire season of competitive sport " . Note the difference between that and the title " Creatine prevents cramping " ! Point is, the studies might be showing no association, but your experience and the experiences of people on the forum seem to indicate that the issue is not cut and dried just yet. Now, I've taken a very long route to actually tackling the problem, but it's worth pointing out that the research is not necessarily definitive in this area. One thing I have learned in my research so far is that the experience of people often counts for more than the best designed research studies! And maybe this is the case here! Now, as for the mechanism, difficult to say why (if at all) creatine would cause cramping. One thing I think we can rule out is dehydration. There are a couple of ways to argue this, but the bottom line is that there is little evidence that dehydration is responsible for cramping of any kind. I'd enourage readers to look through the series we did on this topic (See previous ST posts). point is, you don't cramp because you're dehydrated, or because you've lost electrolytes. I can almost guarantee that when you experience these cramps, if you measured your body weight (as a means to measure hydration) or better still, your electrolyte levels and body water, you'd be easily in the normal range. My personal opinion is the cramps are caused by neurological control factors, with fatigue playing a major role. A fatigued muscles is more likely to cramp, and perhaps there is some mechanism by which creatine enables the athlete to become more fatigued, increasing the likelihood of a cramp? Again, in this regard, it's not the creatine per se causing cramp, but it's an " accomplice " . I also suspect, and this is not borne out by any evidence from research, but is a theoretical argument, that one possible part of the cause of cramp is the water retention that creatine causes. You are no doubt familiar with this, but the retention of water is a side- effect of creatine use. This might be the mechanism for muscle cramp, particularly if the motor nerve-muscle are affected. The other possibility, of course, is that the breakdown products of creatine are responsible. However, I'm not sure of this mechanism either. I think the fact that these perceptions exist is an indication that the problem and its causes is pretty poorly understood. Hope that helps!

Guest guest Posted February 24, 2008 Report Share Posted February 24, 2008 Hi An interesting thought on fatigue. Noakes and his colleagues released papers on the role of the brain and nervous system in fatigue control and management which pointed to a brain control of fatigue onset rather than muscular depletion model - the brains shuts you down to preserve energy for vital functions (and running away from sabre tooth tigers) rather than muscular fatigue (think there were some post on this forum on this topic). I wonder if increased levels of creatine mediate the onset of normal fatigue signalling, so that other systems fatigue before central control by the brain starts the shut down process. I see my water retention postulate seems to " hold some water " :-) Best Regards Nick Tatalias Johannesburg South Africa > > > > > > Hi , > > > > All I know for sure is that it happens and it is very interesting > (as well > > as somewhat Painful) > > > > It almost always happens 1-24hrs after a very high intensity > workout.

Guest guest Posted February 24, 2008 Report Share Posted February 24, 2008 Hi Group I have found a study that I think is interesting, to the topic. J Athl Train. 2003 Jul–Sep; 38(3): 216–219. Cramping and Injury Incidence in Collegiate Football Players Are Reduced by Creatine Supplementation Greenwood,* B. Kreider,* Lori Greenwood,* and Allyn Byars†Abstract Objective: To examine the effects of creatine supplementation on the incidence of cramping and injury observed during 1 season of National Collegiate Athletic Association Division IA football training and competition. Design and Setting: In an open-label manner, subjects who volunteered to take creatine ingested 0.3 g·kg & #8722;1·d & #8722;1 of creatine for 5 days followed by an average of 0.03 g·kg· & #8722;1d & #8722;1 after workouts, practices, and games. Creatine intake was monitored and recorded by researchers throughout the course of the study. Subjects: Thirty-eight of 72 athletes (53.0%) participating in the 1999 Division IA collegiate football season from the same university volunteered to take creatine in this study. Subjects trained, practiced, or played in environmental conditions ranging from 15°C to 37°C (mean = 27.26° ± 10.93°C) and 46.0% to 91.0% relative humidity (mean = 54.17% ± 9.71%). Measurements: Injuries treated by the athletic training staff were recorded and categorized as cramping, heat illness or dehydration, muscle tightness, muscle strains, noncontact joint injuries, contact injuries, and illness. The number of missed practices due to injury and illness was also recorded. Data were analyzed using a 2 × 2 & #967;2 test to examine the first reported incidences of cramping and injury for creatine users and nonusers. Results: Creatine users had significantly less cramping ( & #967;21 = 5.35 P = .021); heat illness or dehydration ( & #967;21 = 4.09, P = .043); muscle tightness ( & #967;21 = 5.39, P = ..020); muscle strains ( & #967;21 = 5.36, P = .021); and total injuries ( & #967;21 = 17.80, P<.001) than nonusers. There were no significant differences between groups regarding noncontact joint injuries ( & #967;21= 3.48, P = .062); contact injuries ( & #967;21 = 0.00, P = .100); illness ( & #967;21 = 6.82, P = ..409); missed practices due to injury ( & #967;21 = 1.43, P = .233); or players lost for the season ( & #967;21 = 4.75, P = .491). Conclusions: The incidence of cramping or injury in Division IA football players was significantly lower or proportional for creatine users compared with nonusers.

Guest guest Posted February 24, 2008 Report Share Posted February 24, 2008 One other hypothesis, if I may add, is to test if taking creatine leads to over-training, because of placebo-type or real gains in volume or intensity. I know that I got cramps after using creatine (and since I knew of this problem, so kept myself hydrated etc.), hence I stopped using it. I also get cramps when I over-train (please reply to my previous questions about over-training in martial arts, if you can shed some light (my questions may be found by searching this mailing list for iaido/aikido/judo etc.)). I have had upper back cramps/spasms after too many sword cuts (1000 or so), and bad abdominal cramps after doing too many aikido rolls. So my hunch is that creatine in itself may not cause cramps, but results in over-training, which causes cramps for some people.

Guest guest Posted February 24, 2008 Report Share Posted February 24, 2008 The biggest issue we run into when it comes to creatine and muscle cramping is that we are still not exactly sure how and why we cramp. It will be very hard for us to answer any questions regarding creatine and its effects when we don't understand the physiological reasons. This aside we can, and will, still create our own hypotheses based on the little things that we do know and understand. So here goes: First off, we can to some degree associate muscle cramping with fatigue. Well this makes things interesting because we still are not sure what exactly causes fatigue though we have some pretty good evidence: http://www.nytimes.com/2008/02/12/health/research/12musc.html?_r=1 & ei=5087 & em= & e\ n=a4100c9a25696de0 & ex=1203397200 & adxnnl=1 & adxnnlx=1203913427-KvYpRGOqI19W6ldHCnK\ 13g & oref=slogin Knowing that creatine can allow people to " do more repetitions " shows us that we do not fatigue as quickly and that the muscle has to undergo a considerably larger amount of work than had the person not been taking creatine. A few things come to mind when thinking about that. When I was hearing that people were complaining of cramps as well as muscle strains and pulls quite a long time ago and were blaming creatine I wondered if the increased work loads had anything to do with it. First off muscle strains and pulls also tend to happen most when in a fatigued state (this is mainly because the muscles are no longer in strong-binding states and thus cannot absorb as much force). Secondly, the muscles in the body are now working a lot more than what they have previously been trained to do. Lets take running as an example here. When you run (depending on the speed of course) you have to absorb nearly 6-8 times your bodyweight onto one leg. If you can do this at a much higher rate for a longer period of time than the muscles and joints are accustomed to the possibility of injury and possibly cramping can become increased because of calcium leakage and neurological fatigue possibly causing inappropriate muscular contractions leading to a loss of proper mechanics and thus a higher liklihood of injury. This obviously just explains why we tend to get hurt and cramp while fatigued and does not necessarily implicate creatine. But because the nervous system and muscles are not used to the amount of work being done one could argue that these kinds of things could be more of an issue early on during creatine use. Obviously. I could go into a much larger treatise concerning the physiology here, but I am sure most of you get the jist of my hypothesis. So Nick and I have given ours. Other hypotheses are more than welcomed.

It > doesn't require a lot of sweating or fluid loss, since my weight training > sessions (except for squats) create very little perspiration. > **** Hi , below are comments from Dr Ross Tucker (http://scienceofspo rt.blogspot. com/): Herewith my thoughts on the issue of creatine and cramping: When creatine was first released onto athletes everywhere, there was a good deal of hype and excitement about the possible performance benefits it offered. And not surprisingly, athletes in all sports launched into its use without really knowing or considering the side effects. I'll never forget my first " exposure " to creatine, was in discussion with the fitness trainer of the Western Province professional rugby team. The trainer is a highly qualified scientist (holds a Masters degree so has a reasonably sound grasp of making inferences based on observation) and he had worked with the same group of professional players for three years before the whole team decided that they needed to use creatine! Now back then, as I said, knowledge and understanding was in relatively short supply, and I'll never forget the story he tells of the first time the players used it. They'd figured that if they ingested creatine during half-time they'd see benefits almost instantly. So during the half-time break, the players all took their mixture. He says that in the second half, 12 out of the 15 players on the field came down with cramp! Now, obviously, they'd been using creatine in the build-up to the game, and so the effect was not simply due to taking creatine at half- time. But he was absolutely convinced that the creatine had caused the cramping. He said they all went off it after that, or reduced the dosage and timing of ingestion, and the problem never happened again. For 12 out of 15 professional players to cramp would suggest something other than co-incidence! I'm not ideally positioned to say he is either right or wrong. I had a look through the scientific articles on the site, one of which says that creatine actually REDUCES cramping, the other finding no effect. My personal thought on that type of study is to interpret with caution - in science, one of the most difficult things around is establishing what we call " causality " . It's very easy to find associations, as these studies have done (Creatine use is ASSOCIATED with reduced cramping), but to actually say that A causes B is very difficult. And in this type of study in particular, there's the problem that whenever you do research, your 'presence' as the investigator alters the normal relationships and systems you're studying! In other words, those studies present very controlled settings, where the training, the diet, the use of creatine and the between training activities are meticulously controlled. That situation does not necessarily hold for your use of creatine and your training. Also, in these kinds of studies, the training benefit of creatine (that is, the groups taking creatine may develop resistance to cramping because they are better trained than the control group. This " confounding factor " might mean that the more appropriate conclusion from these studies is that " Creatine use and proper training will combine to reduce cramping during an entire season of competitive sport " . Note the difference between that and the title " Creatine prevents cramping " ! Point is, the studies might be showing no association, but your experience and the experiences of people on the forum seem to indicate that the issue is not cut and dried just yet. Now, I've taken a very long route to actually tackling the problem, but it's worth pointing out that the research is not necessarily definitive in this area. One thing I have learned in my research so far is that the experience of people often counts for more than the best designed research studies! And maybe this is the case here! Now, as for the mechanism, difficult to say why (if at all) creatine would cause cramping. One thing I think we can rule out is dehydration. There are a couple of ways to argue this, but the bottom line is that there is little evidence that dehydration is responsible for cramping of any kind. I'd enourage readers to look through the series we did on this topic (See previous ST posts). point is, you don't cramp because you're dehydrated, or because you've lost electrolytes. I can almost guarantee that when you experience these cramps, if you measured your body weight (as a means to measure hydration) or better still, your electrolyte levels and body water, you'd be easily in the normal range. My personal opinion is the cramps are caused by neurological control factors, with fatigue playing a major role. A fatigued muscles is more likely to cramp, and perhaps there is some mechanism by which creatine enables the athlete to become more fatigued, increasing the likelihood of a cramp? Again, in this regard, it's not the creatine per se causing cramp, but it's an " accomplice " . I also suspect, and this is not borne out by any evidence from research, but is a theoretical argument, that one possible part of the cause of cramp is the water retention that creatine causes. You are no doubt familiar with this, but the retention of water is a side- effect of creatine use. This might be the mechanism for muscle cramp, particularly if the motor nerve-muscle are affected. The other possibility, of course, is that the breakdown products of creatine are responsible. However, I'm not sure of this mechanism either. I think the fact that these perceptions exist is an indication that the problem and its causes is pretty poorly understood. ================================ Quote Link to comment Share on other sites More sharing options...

Guest guest Posted February 25, 2008 Report Share Posted February 25, 2008 The following should contribute to this discussion. Is it possible that what many are calling cramps is really compartment syndrome? Read below.

The incidence of musculoskeletal injuries and heat illness actually may be decreased by creatine [54]; however, there is evidence that creatine may increase muscle compartmental pressures in the leg [58].
