Quoted message said:Thursday night I swam a mile wearing short fins because I'm trying to
correct an imbalanced kick. I'd used them once before without any
problem. When I was finished swimming Thursday night, I pointed my
toes to take off the right zoomer and my calf cramped like crazy. When
it subsided and I got out of the pool, I noticed both calves felt a
little sore. I spent some time stretching my calves that night, but
when I woke up in the morning, I could barely walk anyway. I walked a
couple of miles on Friday and stretched as much as I could stand, and
Saturday they're improved but still fairly sore. I searched this NG
for similar stories and found people had sore gluteals and upper
hamstrings after swimming with zoomers, but not calves. I'm wondering:
1. Did I use the zoomers wrong?
2. How can I avoid hurting myself like this again?
Yes, you used them wrong(ly).
Cramps from using fins, of the nature and origin you describe, are common.
It happens because the fin allows a greater than normal flexion of the foot;
this means your calf muscles can become shorter than normal; this, together
with the extra work and consquent fatigue is a recipe for cramps.
People who use fins for the first few times should
a) not do a great distance
b) take frequent rests or changes to a non-fin exercise
c) be aware of the possibility of sudden severe cramps
With practice you can increase the total distance, and the amount done
between rest/change, but c) will always be important.
It is unlikely that you have damaged yourself in a permanent way. Next time
you will be more careful - even experienced swimmers using fins can drive
their legs into the same conditions and get cramps like yours - but they are
aware and they will stop as soon as they get the first twinges.
As for the advice from Martin, remember that he's the fellow that recently
suggested another poster here apply oven cleaner to his genitals before
swimming...
