Wearing jewelry while playing a sport is one of the dumbest ways to risk injury -- especially if you do team/contact sports. I always cringe watching baseball players wearing thick, dangly chains... when I was doing competative cheerleading, we were not allowed to wear jewelry or to allow our nails to grow past our fingertips. A girl once hid her nails from the coach and ended up almost slicing her stunt partner's ear off!

I agree. Growing up playing soccer (football) we could never wear any jewelry, not even stud earrings. So I also cringe when I see these athletes playing in loose dangling jewelry. Especially Sharapova, she's always got these extra long dangling earrings that I can't stop imagining one of them getting caught on her racket and...well... you get the picture.

Only a chain bracelet I haven't taken off since I was 15 (apart from that monthI worked in a hospital and couldn't wear jewellery or makeup hah). I agree with the comments, I always see it as dangerous, and above all incredibly uncomfortable to wear jewellery when I'm moving a lot and getting all sweaty!

Nope --- my fingers swell when I run long distances, and I don't want to lose earrings in the water.

Tennis is my game and I love Serena! I know, I digress. Anyway, I wear small stud earrings and a thin bracelet. I used to wear a necklace, too, but all the running sometimes distracts me.

Only a small diamond on a chain that I never take off and occasionally studs if I've just come straight from work and am running, as I often forget to take them out. But certainly nothing dangly.

LOL!
