Background

With the increased popularity of foam rolling (FR), it is important to establish the exact manner in which the practice is useful.

Purpose

The purpose of this study was to examine the impact of FR the iliotibial (IT) band on hip adduction range of motion (ROM) and the short-term time course of any ROM changes that may occur.

Method

In a within-subject design, 34 subjects (21 female, 13 male)(female mean age 24.67±8.6 yrs, height 161.4±9.8 cm, mass 67.3±12.3 kg; male mean age 22±2.5 yrs, height 170.2±8.2 cm, mass 76.3±21.9 kg) underwent a baseline Ober’s test to measure hip adduction ROM prior to the FR and control conditions. Subjects rolled the lateral portion of each thigh for 3 bouts of 20 seconds. A tempo of 3 seconds down and 3 seconds up the leg was maintained across FR bouts. A 5-minute walk served as the control condition. The Ober’s test was repeated at less than 1 minute, 3 minutes …
