Reference number : GC-2017-Q1-00536, amendment number : , agreement type : G, recipient legal name : Stefanyshyn, Darren (University of Calgary), recipient country : CA, recipient province : nan, recipient city : Alberta, recipient postal code : nan, program name english : Engage Plus Grants for Universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : Advances in artificial turf have made these surfaces behave similarly to natural grass, there is still debate as to_x000D_
whether artificial turf is as safe as natural grass in terms of athlete injury risk. Previous research has shown_x000D_
linking rotational traction to lower extremity injury risk. Therefore, artificial surfaces have a potential_x000D_
advantage as the components can be manipulated to alter the rotational traction. In the previous Engage Grant,_x000D_
it was shown that components of artificial turf can influence both mechanical traction and athlete lower_x000D_
extremity biomechanics. In order to further exploit the results of the initial Engage Grant, the influence that_x000D_
additional infill materials have on mechanical traction and athlete biomechanics will be investigated._x000D_
Additionally, the total sample size of the study will be expanded to increase statistical power. The study will_x000D_
consist of both mechanical and biomechanical testing. The mechanical testing performed in the first stage will_x000D_
determine the influence of each infill material of artificial turf on rotational traction. All mechanical testing will_x000D_
consist of rotational traction testing using a proprietary robotic testing machine. Sample sections of artificial_x000D_
turf will be attached to the movable platform and a prosthetic foot will be fitted with a conventional cleated_x000D_
shoe. Four samples of artificial turf will be constructed by FieldTurf with alterations in the infill material_x000D_
(Greenfield, EcoMax, ProMax V2, Walnut) with all other aspects of the turf remaining identical (fibre density,_x000D_
fibre length, infill compaction). Following mechanical testing, turf surfaces may be selected for further analysis_x000D_
if the mechanical testing results in significant differences in rotational traction from the conventional Control_x000D_
surface (conventional rubber infill). Biomechanical testing will determine the influence the new turf on the_x000D_
biomechanics of the lower extremity resultant joint loading. Eight male athletes will perform a running v-cut_x000D_
movement on a 3D force platform mounted in the center of a lab runway floor with each surface securely_x000D_
bolted to the force platform. Kinematics and kinetics will be collected and using an inverse dynamics approach,_x000D_
intersegmental forces and joint moments will be calculated from the motion capture and force data., program purpose french : Advances in artificial turf have made these surfaces behave similarly to natural grass, there is still debate as to_x000D_
