Cramps during the tournament

[marianix]

Hello,
I have a problem during tournaments (doubles). We play 3 matches in a group to one won set.
During the quarterfinals, when I move quickly to the ball or jump, I start to get cramps in my calf.
Has anyone had a similar problem and managed to overcome it? I think stress also plays a role, but that's probably not a solution here. I'm more concerned with what I can do physically.

Pack pickle juice

Pack pickle juice

or mustard packs.

Pickle juice will correct a sodium imbalance, but I've never heard of that in the wintet. More likely lack of conditioning in my opinion.
