Question:
Any advice for cramps in Vastus medialis? I get the cramps late in road races with climbing usually at about the 3 hour mark. I do drink a litre an hour with e-load and eat as much as I can. Does not seem to correspond to hot days. I have not tried stretching during a race yet but hear that might help.
Answer:
The simplest but most difficult solution that I can give you is to train harder or to create training scenarios that make you cramp in training so that your body adapts to a higher work capacity before the onset of cramps. Let me explain.
First, there’s a substantial amount of literature out there suggesting that cramps have nothing to do with fluid or electrolyte balance but have everything to do with basic fatigue either within the muscle or our nervous system that causes a simple but uncontrollable “knee jerk” reflex to be initiated.
- Schwellnus, M. P., Derman, E. W., & Noakes, T. D. (2001). Aetiology of skeletal muscle cramps during exercise: a novel hypothesis. Journal of sports sciences, 15(3), 277-285.
- SULZER, N. U., SCHWELLNUS, M. P., & NOAKES, T. D. (2005). Serum electrolytes in Ironman triathletes with exercise-associated muscle cramping. Medicine & Science in Sports & Exercise, 37(7), 1081.
So you’re right that your cramps probably don’t correspond to hot days or changes in your fluid and electrolyte balance. That being said, this isn’t an excuse to not watch your fluid and electrolyte intake since you’ll have more serious problems than just a cramp if you don’t stay properly hydrated during a race. Moreover, there is evidence that while an electrolyte disturbance or dehydration may not be the sole cause of cramping, drinking a carbohydrate-electrolyte solution can help delay the onset of exercise induced muscle cramps.

Because, cramping may be entirely due to fatiguing muscles the best thing an athlete can do is to get fitter – to get to a point where the stimulus that causes the cramp is pushed back. The fact that most cramps happen in races when athletes are pushing themselves to novel and higher levels of duration and intensity may be a strong indicator that the body just wasn’t prepared for the effort. Thus, working harder in training or simulating efforts that cause cramps might be a worthwhile strategy to prevent cramps in the future.
Still cramps happen, regardless of how hard we train or how prepared we are and because these cramps may be more neurological in etiology, scientists and coaches have tried developing novel strategies for dealing with them. The most interesting in the last year or so has been the idea of drinking pickle juice during a cramp. There has always been anecdotal evidence that drinking pickle juice can relieve cramps in some athletes. So to test that hypothesis, Miller et. al., simulated cramps in dehydrated subjects through an electrical shock then immediately following the induced cramp gave subjects 1 ml of pickle juice per kilogram of body weight (70 ml for a 70 kg or 154 lb person) or plain deionized water. Amazingly, the pickle juice and not water immediately stopped the electrically induced cramp. Though the mechanism for this was not explored, the authors think it may be due to a neurally mediated reflex. Pickle juice is essentially acetic acid, so vinegar may work as well, though no one to my knowledge has ever tested that. Moreover, I’ve never known any athlete to try pickle juice for cramping, so I don’t know if it actually works. But some research is out there and if you ever try it, I’d love to know if it works for you.

What I do know helps is contracting the opposite muscle of the cramp. So in your case, try contracting your hamstring when your quad is cramping. When a muscle is contracting the nervous signal to the opposing or contralateral muscle is cut off. The idea here is that if the cramp is neural in nature, contracting the opposite muscle will hopefully cut off the signal causing the cramp. Of course, stretching and massage the cramp may also help.
One thing I wonder is whether or not you are getting the cramps more in one leg over the other. If this is the case, this may be a sign of a weaker leg or some sort of asymmetry on the bicycle putting more strain one leg. If both legs are cramping equally, I think this is just a case of fatigue. Finally, because these cramps are occurring in your quad, I also wonder if you are sitting fairly forward on the saddle putting more stress on those muscles rather than your gluts. Or it may just be that your quads are the weak link in the chain. Regardless, keep on training hard, keep on stretching, and see if you can simulate the cramps in training so you can not only adapt to a new level but so you can test some pickle juice for me.
