Basketball and Gravity

Every Science Fiction story I have seen or read address the gravity situation in space or on another world. In particular I am thinking of 2001 and Conquest of Space how the spinning of the 'The Wheel' or a segment of the spaceship revolving creates a gravity of sorts that seems to work on the story's humans. I was thinking of the gym used by David and his bicycle and basketball shooting(there may have been some weight equipment in the meeting scene) and how dependent they were on gravity being used. I don't recall any details given in the movie to explain how everyone was able to move around at will seemingly as on earth. My question is about technogy and science and how much time is needed to develop and anti gravity science that could allow for this condition. With our story set less than 100 years in the future are there currently experiments on this needed gravity for the crew to go about their business as if on earth? A gravity field that could be localized might work. Let's assume like our movie shows that there is something in place and in use on The Prometheus to overcome a lack of gravity wouldn't it also be use when on the moons surface? To the use of any practical gravity creation would be of great use on any space travel/terra-forming project that Weyland Corp would be doing in the known Universe and must have been included on this ship on this mission. The implication is that there is also an anti-gravity technology that could be used with great effect. To me seeing everybody being able to move actoss the moon not restricted by the effects of gravity would be a great visual and practical effect for our crew. Speaking of basketball is this sport universally well known in our world? It was a surprising choice to be displayed in our movie. Outside of the USA I would expect a soccer might be more of the universal sport than hoops. Heck a Hockey Rink might be a great addition to the Gym.
