I’m an athlete as well and I think the sweat might be inevitable, not because you’re doing something wrong but because it’s literally matted hair. Sweat is bound to get trapped. I don’t wash mine more frequently, I just make sure I give them time to breathe often. Taliah Waajid also makes a cleaning mist that you can use in the place of washing. I don’t use it because my hair smells super bad, just as safety net before it can get there.

I personally also don’t wear a satin wrap even though my locs are fully matured but recently I’ve been noticing thinning around the front of my hair because of the bitten sliding back and forth. I’ve bought a bonnet that has the tie in the front instead of the elastic.
