Blade-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{New Balance Mens 840v3 Shoes,JSUMING Winter Coats For Women}These studs promote higher friction torque^{Les Trésors De Lily Necklace-plated gold 'Réglisse' black golden.}and improves performance, especially in runs with change of direction,^{View Master 3D Ni Hao,Navachi 925 Sterling Silver 18k White Gold Plated 9.5ct Square Ruby Emerald Sapphire Stud Earrings}compared with round-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229. 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.^{EverEarth 7-in-1 Garden Activity Cube EE33285,Lowa Men's Camino GTX High Rise Hiking Boots-Columbia Women's Flurry Run Down Long Omni Heat Jacket Coat Hooded Parka}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,^{JM Jewellery Ltd QUALITY UK Sterling Silver Cushion Signet Ring 14 x 13mm}as well as greater incidence of metatarsal stress injuries.^{Chatham Men's Kayak G2 Boat Shoes}

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-Mascot 10149-154-010 Charleston Industry Lightweight Short. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
