Values are presented for athletes and non-athletes for inactive recovery in the upright seated position (SeatInact), active recovery in the upright seated position (SeatAct), supine position (Sup), and supine position with elevated legs (SupElev) as means (± SD). * p< 0.05, athletes vs. non-athletes; †  p < 0.01, vs. seated inactive; § p <0.01, vs. seated active.
