It should be noted in many cases its thr athletes' choice. Ironically, in the two examples you mentioned (track and beach volleyball), they are allowed to wear less revealing uniforms and choose not to. Generally speaking, tighter clothes are easier to move in and help increase stability, comfort, and reduce chafing and resistance. Men have dicks and balls, so tight or revealing bottoms aren't as helpful. In basketball, men have more revealing tops than women because boobs. Women tend to prefer tight tops to keep boobs from flopping. Athletes of both genders choose whatever clothes they feel will help them perform better.
