Blade-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{XYSQWZ Pajamas Set For Women Cotton,BERING Bona – Sila Combination Ring Stainless Steel Gold-Plated Tw.

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.^{HMNS Oxford for Men Genuine Leather Metal Pointed Toe Slip-on Loafers Shoes,Smoky Mountain Boots Boys' Snake Print Cowboy Boot Round Toe … Multi Size: 8 Toddler-Shepherd Womens Bella Low-Top Slippers}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,^{ZTMN Watch Box，Wooden，Display Stand/Box Set/Storage Box for Jewelry Watches，Bracelet Collection 12 Grids Display With Glass Lid} as well as greater incidence of metatarsal stress injuries.^{DLYDSSZZ Baby Climb Safety Anti-fall Net Stair balcony window Protection Fence Blocking net for Kids Rope grid safe edges Garden rope Outdoor wall Decor Mesh}

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-Mascot 10149-154-010 Charleston Industry Lightweight Short. 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.

Although there is no direct relationship between the incidence of injuries and the magnitude of the GRF,^{Danner Unisex-Adult Boot Dressing-U Dressing,Rubie's Green Lantern Costume}higher values in the rate of force development in the vertical axis of GRF are associated with stress fractures, especially in the tibia.^{Naomi Ito Naomiitou POCHO organic cotton takes sweat putt two set Ramune 7557,Crystallly Wenzhang Mosquito Net Anti Nets Double Bed Simple Style Stand 4 Colors Optional} However, none of the selected studies looked at this particular variable.
