TORSO ROTATION
Summary
Torso Rotation measures the average angular
rotational range of the chest.
DETAILS
Torso Rotation is the average angular rotational
range of the chest, measured at the sternum once
per second. This measurement is dependent on
the torso’s rotational axis, which closely parallels
the spine: when sitting up, the spine/rotational
axis will be vertical (perpendicular to the ground),
and when in riding position, the spine/rotational
axis will tilt toward the handlebars.
A larger Torso Rotation value indicates greater
average rotation of the torso, and a lower value
indicates more limited average rotation. Although
this motion might be thought of as being similar
to twisting of the torso, it is important to note that
the amount of “twisting” is dependent on actual
torso rotation and pelvic rotation at the time of
measurement.
SCORE
Score Each clockwise and counterclockwise
rotation occurring within a second is recorded
and averaged, resulting in an angular score.
