Boy's Cut and Sew Graphic Raglan T-Shirt,Converse Unisex Chuck Taylor All Star Ox Basketball Shoe}Handling the traction of boot studs is done by increasing or decreasing the penetration of studs on the lawn or by changing the contact area of the boot sole with the playing surface.^{Reusch Soccer Alex Breezer Knicker}This can also be achieved by changing the geometry of studs to a round, conical, triangular or blade shape.^{New Balance Men's 247 Classic}

Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{YPDM robe,Ultrasport Men's Stan Softshell with Ultraflow 5.000}These studs promote higher friction torque^{adidas Men's Athletics Badge of Sport Long Sleeve Tee}and improves performance, especially in runs with change of direction,^{STARBILD Pantaloni Yoga da Donna Anticellulite Elastici Collant Leggings Sportivi,ROTHCO Plus Military Web Belt}compared with round-Chaco Women's Tulip Sandal. 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.^{ChildHat Spa Robe Gym Shower Wrap Bathrobes,XYSQWZ Animal Onesie Adult Fluffy Cartoon Pajama for Homewear Cosplay Party Christmas and Halloween Jumpsuit-Fred Perry Men's Twin Tip Polo Port/White/Navy Shirt}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,^{Napapijri Women's Rainforest Jacket}as well as greater incidence of metatarsal stress injuries.^{Rockport Men's M7100 Milprowalker White Derbys}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,£178.42£178.42, 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-£185.86£185.86. 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.
