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.^{HangAir Underwater Kinetics Hanger For Drying Wetsuits,Reebok Women's Training Supply Muscle Tank Top-Reebok Unisex-Child CN1343 Royal Cl Jogger 2}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,^{Mascot 00525-590-01 Dundee Originals Thermal Jacket}as well as greater incidence of metatarsal stress injuries.^{Tuscany Silver Sterling 100 Byzantine Bracelet of 20cm/8.5"}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Clarks Women's Hamble Oak Derbys, 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-Clarks Women's Hamble Oak Derbys. 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.
