Objective:

To determine the relationship between lumbopelvic (LP) stabilization strength and pelvic motion during running.

Design:

Runners were assessed for pelvic motion and undertook an LP stabilization strength test.

Participants:

Sixteen elite male middle- and long-distance runners.

interventions:

Pelvis kinematics were assessed while subjects ran at 5 m/s on a treadmill.

Main Outcome Measures:

Angular pelvis displacement was divided into 3 axes of rotation: pelvic tilt, obliquity, and rotation. LP stabilization strength was the capacity to resist increasing static loads applied to each leg and maintain a neutral LP zone. Intercorrelations were calculated for all measures of pelvic motion and LP stabilization strength.

Results:

There were no significant relationships found among any of the variables (P > .05). However, the LP stabilization strength test possessed good interday reliability.

Conclusions:

The relationship between pelvic motion and muscle function should be studied under a variety of other conditions.
