Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Wildkin Horse Dreams Pencil Case,Relco Men`s Overcoat Black With Red Lining}These studs promote higher friction torque^{SHOULIEER Men Military Boots Quality Special Tactical Desert Combat Ankle Botas Army Work Shoes}and improves performance, especially in runs with change of direction,^{The Scotland Kilt Company Co 5 Hunting Stewart Piece Package inc Sporran & Hose,HENGX Girl Dress/Party Costume/Long-Sleeved Floor Dress/3D Embroidery Flowers/Lace Sequins/Fluffy Skirt/Zipper/Luxurious Princess Dress/Winter}compared with round-Glenna Jean Central Park Bumper. 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.^{Rebecca Minkoff Women's Nylon Tote,Delsey Paris Garment Lightweight Hanging Travel Bag-super.natural Women's Knit Hoodie}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,^{Livia Women's Isabel Lavandou Swimsuit}as well as greater incidence of metatarsal stress injuries.^{XLC Winter Shoes Cb M07}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Rieker Womens 60843 Closed Toe Sandals, 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-Silver Insanity Women's Sterling Ring. 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.

RESULTS

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Napapijri Men's Jacket}After the duplicates were removed, 107 articles remained.
