Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Mianbao Rug Carpet Living Room Bedroom Fashion Cartoon Nursery Modern Home Play Baby's Patterns Hallway Terrace Kitchen Yoga Personality Dormitory Kids 200 x 300cm,Craft Sportswear Men's In-the-Zone Full Zip Casual Training Long Sleeve Hoodie Jacket}These studs promote higher friction torque^{F.A.

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.^{PLwedding Boy's 5 Pieces Tuxedos Toddler Formal Suits Set Kids Slim Fit Suit for Weddings - Brown Small,adidas Mens Cf Revolver-ASICS Women's Favorite Shimmel}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,^{Matt & Nat Drew Large Vintage Shoulder Bag}as well as greater incidence of metatarsal stress injuries.^{Sanuk Women's Chiba Chill Loafer Flat}

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.

Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{Keen Men's Newport Sport Sandal,Ian and Valeri Co.
