    Introduction: Self-myofascial release using foam rolling (FR) has become increasingly popular in the prevention and recovery of muscle trauma and overuse. Its effects on tissue regarding changes in stiffness properties are poorly understood. The aim of this study was to investigate the role of FR on muscle and ligament stiffness using acoustic radiation force impulse (ARFI) elastography.

    Material and Methods: ARFI-based elastography (Acuson S2000 Ultrasound System, Siemens Healthineers, Erlangen, Germany) was performed in 40 volunteers (20 with > 6 months of experience in FR and 20 without any experience) before and several times (0, 30, 60, and 120 minutes, and 12 and 24 hours) after a standardized FR exercise of the lateral thigh. The exercise protocol consisted of four sets, each with 45 seconds of FR on the lateral thigh in the sagittal plane. Tissue stiffness was assessed at the lateral thigh (vastus lateralis muscle [VL], vastus intermedius [VM], and distal insertion of the iliotibial band [ITB]).

    Results: Tissue stiffness of the ITB revealed a significant decrease of 13% in experienced athletes at 30 minutes postintervention (p = 0.002). In inexperienced athletes, a 6% increase of stiffness was found at 30 minutes postintervention at ITB that was not significantly different than baseline (p = 0.16); no significant changes occurred at later time points at ITB. For VLM and VM, no significant changes were detected at any time point in both groups.

    Conclusion: A significant short-term decrease of connective tissue stiffness in athletes experienced with FR is detectable with ARFI. Athletes’ experience in FR is relevant, emphasizing necessary training before successful application.
