Blade-Oil Resistant Pressure Flexible R6 Hydraulic Rubber Fuel Hose, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{150# ANSI 304L Stainless Steel Forged Lap Joint Flange,Wireless Charge Table Socket}These studs promote higher friction torque^{Australia Style Fence Metal Steel Aluminum Fencing Pool}and improves performance, especially in runs with change of direction,^{Bespoke Artificial Acrylic Stone Countertops for Kitchen Table Top,Dove Glass Prisms}compared with round-Oil Resistant Pressure Flexible R6 Hydraulic Rubber Fuel Hose. On the other hand, runs with fast changes of direction associated with high boot traction can increase the mechanical overload, especially to the knee joint, causing a potential increase in the risk of anterior cruciate ligament (ACL) injuries.^{F Series Parallel Shaft Helical Gearbox with Flange Connection,Sheet Metal Parts- Stamping Die-Metal Bracket Parts-Stamping-Aluminum Ceiling Industrial Control LED Low Bay Light with CE}Besides that, the greater traction promoted by the penetration of the studs in the lawn can promote greater peaks of pressure on the sole of the feet,^{Women Fashion Hotsales Short Sleeve Round Neck Sweater Clothes}as well as greater incidence of metatarsal stress injuries.^{High Quality Hot Sales Fresh Cut Flower Wakeup Rose for Wedding}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,1000W Subwoofer Amplifier PA System, studies related to the influence of boot studs. After exclusion of articles that did not meet the inclusion criteria, the remaining articles were selected to be fully read and those that did not investigate overload due to the use of blade-Wear-Resistant and Non-Slip Spc Floor. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results. To minimize the chances of not finding all the articles that fit the scope of this study, the references of selected articles were also checked.
