Actually, American beach volleyball player Kerri Walsh Jennings is famous for smacking the bottoms of her partners often during their matches. I've seen her do it with her current partner April Ross, but she did it consistently with her now-retired partner Misty May Treanor, with whom she won three straight Olympic gold medals (2004, 2008, 2012). Poor Misty must have had a bruised left cheek after a lot of these matches because Kerri Walsh was not shy about delivering a substantial swat each time she did it. They (Walsh-Jennings and Ross) are favored to win gold again this year, so there's likely more opportunities for her to "spank" her partner. Most of the women are in
very skimpy bottoms (as far as I'm concerned they could just play in thongs...) but they usually wear "full coverage" tops and, of course, they're professional athletes in
superb shape and have magnificent little bottoms.
Traditionally, female gymnasts aren't exactly top-heavy (lower center of gravity) as well as being quite young and the female beach volleyball players are usually tall and quite lean so "bouncing" isn't really much of an issue. The gymnasts' costumes do look almost sprayed on and I wouldn't be surprised if they "glue" the bottom parts of the costumes to the girl's bodies so there's no "slippage" under extreme activity.
Sports bras or no, I remember a few boob "fall-outs" during tennis matches from some of the better-endowed female players, but not necessarily at the Olympics.
I am always totally amazed at the abilities of the gymnasts (both male and female) and how they can flip and do somersaults and twists and then land on a balance bar only a few inches wide but, strictly for entertainment, I prefer women's beach volleyball. Couldn't care less about the men...
