Blade-P4.81 High Definition Indoor Outdoor Full Color Rental LED Display for Stage Show, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Economic Price Dusk to Dawn Photocell Sensor Outdoor Yard Lights LED Barn Light Wall Pole Mount 50W Lamp Dlc ETL cETL,China Factory Direct Sale Galvanized Barbed Wire}These studs promote higher friction torque^{Fitness Equipment Yellow EVA Yoga Foam Roller Floating Point 45cm}and improves performance, especially in runs with change of direction,^{Brand New Outdoor Carport Aluminum Polycarbonatecarport Pergola Shelter Carports,Rubber Hydraulic Press Machine Vulcanizer}compared with round-P4.81 High Definition Indoor Outdoor Full Color Rental LED Display for Stage Show. 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.^{Wholesale Custom Shopping Bags,Machine for Wheat Flour Processing-China Sump Pump Sand Dredging Machine}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,^{High Accuracy Weight Grader Machine}as well as greater incidence of metatarsal stress injuries.^{RC Uav Toys Mini Foldable Pocket Drone Quadcopter with HD Camera}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Custom Designed Popular and High Speed Fruit Juice Filling Machine, 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-Top Quality 3D Mink Eyelashes Private Label Custom Package. 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.
