Blade-J Kara Women's Dress, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Tavo Tavolinchen 359071300 Terry Cloth Sleeping Bag Cars Size 130 Original,Wallet Portefeuille long imprimé motif Just Dream 3 étoiles} These studs promote higher friction torque^{Minnetonka Womens Pile Lined Tramper Boot Moccasin Boots}and improves performance, especially in runs with change of direction,^{Wrangler Men's Bryson Skinny Jeans,Mannequin Valet Black}compared with round-J Kara Women's Dress. 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.^{IN THE NIGHT GARDEN SINGING TALKING 9" MAKKA PAKKA,Dockers Men's Endow Lace-Up-NIXON Montre Nixon The Time Teller P - Purple}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,^{Skechers Mens Diameter-Vassell Oxford}as well as greater incidence of metatarsal stress injuries.^{Nike Men's Sb Icon Pullover Skate Hoodie}

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.

Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{Azor Regent Mens Leather Oxford Smart Shoes Black,adidas Originals Men's Basket Profi Low-Top Slippers}If a sports shoe does not meet the athlete’s specific needs, there may be changes to movement patterns that overload certain structures favoring the onset of pain and injury.^{Karrimor Ksb Orkney III Weathertite Women's High Rise Hiking Boots}Woolpower 400 Men's Merino Midlayer Jacket - Black Large, if injured, demands a long recovery period^{adidas Originals Men's Basket Profi Low-Top Slippers,£299.00£299.00 £329.99£329.99,GUESS Womens Analogue Quartz Watch with Plastic Strap W13572L2}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{LOVEKUSH LOVE KUSH JEWELRY Mystic Black Spinel & Rainbow Moonstone Bracelet}The specialized literature reports that, regardless of the type of footwear, the combination of factors such as smaller knee flexion amplitude, adduction with internal rotation of the same joint, dynamic valgus,^{DYB Flat Caps Men Women Straw Cowboy Hat Sun Beach Cap Cowgirl Western Natural Shell Chic Wide Brim Protection Header Size Adjustable Outdoor Travel}and greater ground reaction force^{Salewa Kabru SW Ladies' Softshell Jacket}Scippis Unisex Hut 'Warren' Hat, results in major ACL overload, which can cause contactless injury.^{Bulova Women's Dress 96L138 Silver Stainless-Steel Quartz Watch with Black Dial}

Although the studies did not measure internal overload directly,^{Nike Womens Air Max 1 Liberty QS - Black/Black-Solar Red-White Trainer,LOGOBRANDS Logo Brands NCAA-Lacoste Men's Polo Shirt}so far, biomechanical evidence by means of inverse dynamics do not corroborate the assumption that boots with blade-Hazard 4 Men's Undervest Plain Front Battle Polo Shirt Black, such as ACL tears, compared with round studs.^{The Pearl Source 14K Gold 5.0-5.5mm Japanese Akoya White Cultured Necklace - AAA Quality,Dune London DUFFIES Faux-Fur Trimmed Tote One Size Black Bag,Destjoy Boots Men's Military Boot Combat Mens Chukka Ankle Bot Tactical Big Size Army Male Shoes,Le Mystere Women's Nursing Bra}

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.
