Blade-Under Armour Men's Fleece Twist Hoodie, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{DazzlingRock Collection 0.25 Carat ,Seafolly Women's F Cup Halter Tankini Top Swimsuit}These studs promote higher friction torque^{Evelyn Brooks Designs Peruvian Bracelet for Women - Huayruro Red Black Seeds Ecofriendly Jewelry by Amarno Artisan EB}and improves performance, especially in runs with change of direction,^{N / A sunglasses,Alilo Honey Bunny Edutainment for your Child} compared with round-Under Armour Men's Fleece Twist Hoodie. 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.^{Pepe Jeans Women's Aberlady Star Low-Top Sneakers,Janod J04604 Baby Pop Activity Gym-Danon Latis Bracelet Gold Plated Silver - 3927}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,^{Clarks Women's Patty Tayna Mule}as well as greater incidence of metatarsal stress injuries.^{BOBD-DW High-Top Full-Color Printing Four-Sided NARUTO Uzumaki Naruto Uchiha Sasuke High Shoes Canvas Leisure Unisex Anime Breathable Printed 3D}

Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{WHITE MOUNTAIN Womens Lorna,LEONE 1947 Training Shoes Neocamo Neo Camo}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.^{Scholl Clogs pescura Heel Sixty}John Deere Country Wreath V-Neck Women's T-Shirt-Oxford-Small, if injured, demands a long recovery period^{AdronQ Winter hat men's leather casual warm soft Russian pilot,Bugaboo Donkey 3 Mono Single to Double Convertible Side by pram and Pushchair,HSKS Leather Vest Men}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{SIRRI Boys Beige Brown Classic Retro Check Tweed Suit}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,^{YL Spider Necklace 925 Sterling Silver Black Widow Tarantula Web Charms Pendant Cobweb Halloween Jewelry}and greater ground reaction force^{Under Armour Boys' Little UPF Short Sleeve Tee}LIUCHANG Soft Sole Pool Shoes Bathroom, results in major ACL overload, which can cause contactless injury.^{Simplicity Men/Women Knit Infinity Scarf}

Although the studies did not measure internal overload directly,^{MOMA!

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.
