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.^{Grand Conquest,Music City Metals 91301 Steel Wire Rock Grate Replacement for Select Gas Grill Models by Amberlight-adidas Men's Gazelle Fitness Shoes}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,^{LONDON FOG Boy's Down Alternative Coat}as well as greater incidence of metatarsal stress injuries.^{Samsonite Laptop Backpack Medium Debyte}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Dickies Men's WS574 Hanging Short Sleeve Work Shirt, 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-Dickies Men's Thermal-Lined Fleece Hoodie - Black Medium. 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.
