Objective: 1) Characterize the workday habits of American jockeys, and 2) Evaluate the relationship between workday habits and fatigue through changes in postural stability (balance) across their workday.
Methods: Thirty-seven jockeys participated in pre- and post-race day testing. Jockeys completed questionnaires on workday habits and a two-minute balance test with tri-axial accelerometers on the unstable surface and sacrum.
