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.^{Alex Evenings Women's Blouse,CHENTAOCS Shoehorn 70cm wooden long handle to send elders the best gift}These studs promote higher friction torque^{Georgia Boot Men's 8" Wedge Work}and improves performance, especially in runs with change of direction,^{Rosec Jewels 3.19 Carat Heart Shaped Peridot Certified Diamond Halo Earring,Wrangler Men's Jeans}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.^{Bekina Thermolite Polyurethane ,Persol Sunglasses-LLT Durable Safety Net Child Protective Decoration Out Prevent Children Climbing Net}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,^{Nike Men's Air Max Ivo Low-Top Sneakers}as well as greater incidence of metatarsal stress injuries.^{Betsey Johnson Women's Jogger Sweatpants}

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.
