There seems to be a large rise in popularity with Crossfit and Crossfit type gyms. These types of gyms seem to pop up anywhere and everywhere.  The type of workouts these gyms typically have seem to have much larger and more frequent high-impact floor loading (i.e. dropping barbells from chest or overhead 30+ times in a workout). This high-frequency/high-impact loading could be a larger issue over a wood joist/plywood raised floor (i.e. not a slab-on-deck), such as when a gym owner wants a gym in the second story of a retail building. 

Are the IBC/ASCE7 load requirements for gym floors sufficient for design in these conditions or should they be modified to adjust for what appears to be a more high-frequency/high-impact loading?  Are there other considerations (floor finish, etc) that should be taken into consideration to minimize the effects of this loading?  Any articles or examples of retrofitting raised non slab-on-deck floors for this type of occupancy would be very appreciated!
