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.^{Merrell Men's Trail Glove 5 Fitness Shoes,adidas Harden Stepback Track Shoe}These studs promote higher friction torque^{Aravon Womens Maya}and improves performance, especially in runs with change of direction,^{Casio – ltp-1302l-7b Classic Ladies Watch Analogue Quartz White Dial Black Leather Strap,The World Jewelry Center 14k Yellow Gold Flower Stud Earrings with Screw Back - 12 Different Color Available}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.^{HKM Women's Reithose -Stretchy- 3/4 Besatz Trouser,Craft Men's Essence Jersey M-GJQION Siamese Silicone Breast Forms}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,^{Wrangler Women's Aura Slender Stretch Jean}as well as greater incidence of metatarsal stress injuries.^{REYUAN Men's Watch}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Remonte Women's R3370 High Boots, 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-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. 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.
