There is some guidance from Sport England under the title, "Floors for Indoor Sports" at:- http://www.sportengland....rtBy=alpha&pageNum=2 "For most sports the degree of friction between the player's shoes and the surface needs to be high enough to prevent slipping, but not so high as to restrict foot movement either in a continuous direction or when turning, or prevent the controlled sliding of the foot that is required in some sports." It is not going to give you specific values, but the professional suppliers of floor finishes or architects should be able to assist. You may want to refer to the publicatio0ns below, but I doubt they are specific to sports!:- The "Specifiers’ Handbooks for Inclusive Design-Internal Floor Finishes" .
