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.^{Richter Kinderschuhe 31.5808.3401,Tommy Hilfiger Gents Watch 1790684}These studs promote higher friction torque^{Teva Girl's K Ember Moc Slipper}and improves performance, especially in runs with change of direction,^{SUPRIMA Suprima 9611 PVC Unisex Washable Pyjama Top ,Laura Vita Women's 3115 Satchel}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.^{Aqua Quest The Tote Waterproof Backpack - Charcoal,Dickies Waterproof Heavy Duty Padded Overall -Henschel Water Repellent Safari with Leather Band}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,^{FTNJG Portable Mobile Nursery Organizer}as well as greater incidence of metatarsal stress injuries.^{Tommy Hilfiger Womens Multi dial Quartz Watch with Stainless Steel Strap 1781847}

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.

On the other hand, due to the small sampling number (n = 6) and the methodological limitations in the treatment of electromyographic signal, interpretations of these results should be made with caution.
