Description of hip muscle strength measurements

Strength measurements	Strap placement	Position	Procedure	Figure
Hip extensor	Distal thigh	Prone	The examiner controlled the participant's lumbopelvic rotation (pelvic anterior tilting) during hip extension. Participants performed hip extension against a strap to maximal voluntary isometric contraction (MVIC).
Hip abductor	Ankle	Supine	The examiner controlled the participant's lumbopelvic side-bending during hip abduction. The hip and knee joint of the dominant leg was extended to 0°. Participants performed hip abduction against a strap to MVIC.
Hip adductor	Ankle	Supine	The examiner controlled the participant's lumbopelvic side-bending during hip adduction. The hip and knee joint of the dominant leg was extended to 0°. Participants performed hip adduction against a strap to MVIC.
