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.^{MILLY Women's Blouse,PUMA Infants & Toddlers Angle Tricot Set 1/4 Zip Top and Track Pants} These studs promote higher friction torque^{MIBKLPG Women Hoodies Coat New Solid Color Casual Sweatshirt Oversized Hoodie}and improves performance, especially in runs with change of direction,^{adidas Originals Men's Sweatshirt,Grand Conquest}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.^{Music City Metals 91301 Steel Wire Rock Grate Replacement for Select Gas Grill Models by Amberlight,LONDON FOG Boy's Down Alternative Coat-Minnetonka Double Fringe Tramper Ankle Boots/Boots Femmes Brown Mid Boots}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,^{Samsonite Laptop Backpack Medium Debyte}as well as greater incidence of metatarsal stress injuries.^{BDI Cycling Apparel Men's Mountain Bike Cargo Short}

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.

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Lambs & Ivy Luxury Enchanted Forest Cot Bumper}After the duplicates were removed, 107 articles remained.

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.
