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.^{Small MOQ 590ml Dry Quickly Neutral Weatherproof Silicone Sealant,Custom Shape Soft Enamel Pin Badge with 3D Wing-Prefabricated Steel Frame Workshop Homes Tiny Kits Modular Modern Low Cost Cheap Hurricane Proof Villa Luxury Prefab House}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,^{Water Based Waterproof Interior Malay Paint}as well as greater incidence of metatarsal stress injuries.^{Ce Approved Laptop Ultrasound Scanner with LCD Screen FM-3000b}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,High Quality Custom Rubber Ferrules / Tips/ Caps Feet for Crutchs, 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-LLDPE LDPE HDPE Plastic Granules Black Masterbatch. 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.

Only one study^{Custom Packaging High-End Quality Food Grade Coffee Bag}evaluated the electromyographic activity of the thigh muscles, and showed lower electrical activity of the quadriceps muscles caused by blade-2.2kw 300Hz Er25 Square Air Cooled CNC Router Spindle for Woodcarving/Wood Engraving-Medical Device Mould Vacuum Blood Collection Tube Injection. 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.
