How do Jewish basketball players keep their yamikas from falling off while they’re running around jumping and free throwing the ball and stuff?

I am a non-Jew and I’m not trying to be ignorant. I saw a clip of a basketball game with two Jewish teams playing with their yamikas on and it was super cool but I was wondering like how do they keep their yamikas from falling off while running and jumping and playing such vigorous sports?

Is there a beret or something so it is clipped into the hair or a comb? What if they run into one another? How does the yamika stay on the head?

Again I apologize if this is an insensitive question I am just a clumsy woman but I know if I had to wear a yamika and play a sport it would totally fall off my head.
