I’ve always noticed that when I'm swimming cramps seem to come out of nowhere. The worst cramp to me is the arch cramp in your foot. It’s hard to prevent and is tough to get rid off. Hydration is the best way to prevent cramps in your calves, obliques or abs. The arch cramps are usually the result over pointing (flexing) your toes.
The popular notion is to stop and pull your toes towards your knee. I’ve never found that as a productive solution. When your muscle cramps it is contracting, the reaction to “stretch it out” or pull in the opposite direction it is contracting isn’t effective. So by yanking on your muscle, you’re doing exactly the opposite of what your muscle wants to do. This will only make it hurt worse or, at best, provide temporary relief.
I’ve had success with stopping and finding the contracting muscle and massage it out. This works in your calf and the arch of your foot. My arch cramped today near the end of my workout. Instead of pulling on my toes, I found the cramping muscle near my heel and starting massaging it. After about 90 seconds, the muscle relaxed and I continued my swim (careful not to over point my toe.)
Note: I am not a doctor. Your mileage may vary. The muscle I think was cramping were the abductor hallucis. The muscle in my left foot was soft and squishy, the muscle in my right foot was solid and the size of a golf ball.
