Moves (aka tricks) in Footbag Freestyle are made up of components. Components of a move done while the footbag is at the apex of its parabolic motion are called “midtime” or “hangtime” components. (The latter because the footbag appears to be hanging in mid-air for the duration of the component in question.)
See the page on parabolic motion for a diagram that illustrates this more clearly.
Examples of midtime components:
- certain spins
- most gyro dexterities
See the Freestyle Set List for an expansive list of possible midtime/hangtime components.
