Positioning of the IMU sensors for the measurements.
IMUs were positioned on each rider according to the manufacturer guidelines (https://www.noraxon.com/noraxon-download/myomotion-system-user-manual/).
Table 1.
Tölt performance and rider asymmetry variables for each rider-horse interaction.
FAbs = Mean total absolute force of the left and right feet combined as measured from the foot force sensors; FDiff = Absolute mean difference between the left and right foot forces as measured from the foot force sensors; RollP = Side- to- side movement (roll) of the pelvis; RollT = Side- to- side movement (roll) of the thoracolumbar region; LAP = Lateral advanced placement; DF = Duty factor; Left = Left rein; Right = Right rein.
Table 2.
Mean ± SD rider asymmetry and performance variables during tölt riding on left and right reins.
FAbs = Mean total absolute force of the left and right feet combined as measured from the foot force sensors; FDiff = Absolute mean difference between the left and right foot forces as measured from the foot force sensors; RollP = Side- to- side movement (roll) of the pelvis; RollT = Side- to- side movement (roll) of the thoracolumbar region; LAP = Lateral advanced placement DF = Duty factor.
