Influence of Compliance and Aging of Artificial Turf Surfaces on Lower Extremity Joint Loading

Background: Artificial turf (AT) has been related to increased injury rates when compared natural grass (NG). One potential reason for the differences in is difference mechanical characteristics of surfaces. Over course a season on artificial turf, due heavy use and environmental factors, properties surface (such as compliance) may be altered. The purpose was compare effects newly installed versus aged AT risks at metatarsophalangeal, ankle, knee joint during soccer-specific movements. Methods: Eleven male soccer players performed three movements ‘aged’ AT. Kinematics kinetics were collected different Results: Knee adduction moments v-cut (119 Nm vs. 164 Nm, p = 0.02), external rotation circle run (23 28 0.04) with surface. No seen jog-sprint transition. Conclusions: For associated high risk non-contact injuries, age resulted greater factors joint. Further research comparing should consider features, specifically compliance.
