There is no consensus on the impact forces needed to produce a fracture. There were no significant differences in the maximum force (p > 0.05) among the Adidas Predator and the Adidas UCL and the Nike Mercurial, However, significant differences were observed between the impulse values of the Adidas Predator and the other shin guards (p < 0.05) (Adidas Predator had the highest transmitted values). 2022 Leon Paul London, all rights reserved. HIF trials and a comparison of the groups. The previously prepared lower leg model (artificial tibia covered with EVA) was used for the modeling of these shin guards by taking a Paris plaster. about navigating our updated article layout.

Before In some studies wooden (Lees and Cooper, 1995) or car-crash dummy (Bir et al., 1995) tibia models have been used in shin guard tests. Impulse (force*time) is the most important parameter for evaluation of the protective efficiency of shin guards. In this context, using the appropriate material and applying the right geometry are important aspects of football equipment design (Adrian, 1996). The absorption rates obtained in this study were comparable to those identified in the study by Ankrah and Mills, 2003, in which they placed a similar sensor system on the cover around the tibia, under the shin guard. If you do not allow these cookies then some or all of these services may not function properly. This highlights the main disadvantage of PP-based shin guards; however, it is obvious that choosing the right padding material requires as much care as the selection of a shell. (2000), Complications of tibial shaft soccer fractures, Winston R.C., Zain K., Susan D., William J.L. When you visit any website, it may store or retrieve information on your browser, mostly in the form of cookies. Soccer Shin Guards for Kids Adults incl. A well-designed shin guard should provide adequate protection for the shank, but allow range of motion of the ankle and the knee (Eugene, 2003). The site is secure. The core (tibia) models were covered with human soft tissue-like material (EVA), similar to the one used by Ankrah and Mills, 2003 in their study. Moreover, Ankrah and Mills, 2003 showed that the models they tested absorbed the maximum force by 86-93%. (2000) support this conclusion. Football is the most popular team sport worldwide; therefore, it is particularly important that the risks associated with this sport are managed effectively. The adaptor at the lower end was fixed to the human-like SACH-type prosthetic foot applying the appropriate prosthetic technique. In addition, using a prosthetic foot to simulate the human foot instead of some rigid material as the unit delivering the impact and putting a football cleat on it during the kick ensured that the trials mimicked real impacts, thereby differentiating this study from others. Whether you want ultra-secure pads with ankle support or easy access with a slip-on design, you can find all the essential looks from the biggest brands. Based on these same parameters, the Nike Mercurial provided better protection than the Adidas Predator and the Adidas UCL (p = 0.000). In the HIF trials 5.16-10.90% of the load was transmitted to the sensors (Table 4). n.s. During LIF trials, the maximum force measured by the sensors attached in front of the tibia under the shin guard was 26.49-79.36 N. This demonstrates that only 2.79-9.63% of the loads applied were transmitted to the front of the tibia (i.e., 97.21-90.37% of them were absorbed). A SACH-type prosthetic foot (Otto Bock Company, Germany) was placed in front of Load Cell-1 and an injection-type football cleat was put on the foot (, The impact mechanism of the experimental set up was designed to hit the shin guard by the heel of the foot (an area of approximately 20 cm. When comparing the maximum force and the impulse, a significant difference was found between the shin guard models (p = 0.000). 8600 Rockville Pike Phillipens and Wismans, 1989 reported that the peak force decreased by 28-53%. To eliminate deformations of shin guards during trials, the repetitions for the impacts were limited to 13. Shin guards provide shock absorption and facilitate energy dissipation, thereby decreasing the risk of serious injuries. Received 2013 Apr 16; Accepted 2013 Oct 7. 1Faculty of Medicine, Physical Medicine and Rehabilitation Department, Prosthetics-Orthotics and Rehabilitation Center, 2Physical Education and Sport Faculty, Marmara University, Istanbul, Turkey. Two of the artificial tibias produced were used to test load levels lower than 3000 N, which is the predicted fracture threshold impact force/loading values in cadaver models (Heiner and Brown, 2001). Shop products from small business brands sold in Amazons store. In this study, the sensors were attached to the front of the tibia on the soft tissue covering the whole surface under the shin guard. (2007), Tibial shaft fractures in football players, Journal of Orthopaedic Surgery and Research, http://files.leagueathletics.com/Images/Club/6097/The%20Prevention%20of%20injuries.pdf. nonsignificant. In this context it was crucial to plays the sensor systems on the tibia. (2000), Comparison of soccer shin guards in preventing tibia fracture, Gainor B.J., Piotrowski G., Puhl J.J., Allen W.C.

This tension was set at 142.2 N for LIF trials and at 255.1 N for HIF trials. All information these cookies collect is aggregated and therefore anonymous. The guard slides between the fencers sock and the shin and is only required on the front leg. Carbon shin guards with EVA and neoprene liners gave comparable results for the maximum force and the impulse values at low-level impacts. When comparing the maximum force and the impulse, significant differences were found between the shin guard models (p = 0.000). non significant. They help us to know which pages are the most and least popular and see how visitors move around the site. The resistance of each tibia was tested until the 3000 N load was reached. Commercially available Polypropylene based shin guards do not provide sufficient protection against high impact forces. Many authors agree that shin guards may reduce the number of minor injuries (rnason, 2004; Ekstrand and Gillquist, 1982); however, it is unclear whether they can prevent more serious injuries such as tibia fractures. The Nike Mercurial shin guard provided better protection than the Adidas Predator and the Adidas UCL (p = 0.000); the Adidas Predator and the Adidas UCL were similar (p > 0.05). The aim of this study was to compare the protective effectiveness of polypropylene based shin guards with custom-made carbon fiber ones. The International Federation of Association Football (FIFA), as the international governing body, created FIFAs Medical Assessment and Research Centre (F-MARC) in 1994 to investigate and to prevent football-associated risks to players health. They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms. All shin guards were able to provide adequate protection in that range. Lees and Cooper, 1995, Ankrah and Mills, 2003 and Barrey, 1998 reported that the protection by shin guards would not be sufficient in high force impacts which could cause a tibia fracture. Tackles causing injuries frequently produce tears or damage to the shin guard. Using standard size shin guards do not always allow perfect fit and protection. The protective properties of commonly used shin guards were compared with specially designed carbon ones. Choosing a selection results in a full page refresh. An adapter similar to the one on the lower end was mounted on the upper end of the artificial tibia, and a prosthetic knee joint 3R15 (Otto Bock, Germany) was attached. Material:58 % nylon, 17 % polyester, 14 % elastane, 11 % rubber, Use left/right arrows to navigate the slideshow or swipe left/right if using a mobile device. Francisco et al., 2000, observed an average absorption rate of 11-17% with the use of shin guards. The use of shin guards may not prevent fractures (Ankrah and Mills, 2003; Barrey, 1998). During HIF trials, the maximum force values measured by the sensors attached to the front of the tibia under the shin guard were 143.95-262.41N. A special sensor system (Tekscan, F-Socket system), 0.18 mm thick with 0.6 sensors per cm. The main concern when formulating this standard was to avoid any harm that could be caused by a strikers cleats; high kinetic energy impacts and the related consequences were not taken into consideration. n.s. Although soft tissue injuries such as strains, sprains and contusions frequently result from playing football fractures are more important (Hawkins and Fuller, 1999; Junge et al., 2004). During high-energy impact trials, these three shin guards responded similarly even though there were differences in the thickness of the liner. will also be available for a limited time. In this study, three artificial carbon fiber tibias were produced as described by Heiner and Brown, 2001. They do not store directly personal information, but are based on uniquely identifying your browser and internet device. The experimental setup had the following parts: 1) A pendulum attached a load cell at the tip (CAS Corp., Korea) and a fixed prosthetic foot equipped with a cleat to simulate an attackers foot. Polypropylene shin guards bend more because of being plastic-based and forces acting on the tibia/soft tissue longer. A football cleat was mounted on the foot delivering the blow to ensure that the impact was caused by the spiked portion of the sole.

The fact that the sensors were placed in similar positions might be the reason for the close results with the present study. Although many authors advocate the use of shin guards, the ideal structural design characteristics have not been specifically defined. A special device with pendulum motion was designed for this purpose (. To increase energy absorption, the shin guard shell should be thick and rigid in the transverse direction; however, an increase in length does not provide better shock absorption (Ankrah and Mills, 2003; Francisco et al., 2000). Although this argument does not concur with the opinion of Francisco et al., 2000 that thicker shin guards will provide better protection, the low number of products tested prevents us from giving any definitive judgments. This proves that we produced tibias with a resistance level close to those recommended in previous studies (Heiner and Brown, 2001). The Carbon-1 (EVA) shin guard tested in the low impact trials was damaged by non-experimental reasons (it was broken accidently during a transfer following a LIF trial) and therefore excluded from the high impact trial statistics. Despite the fact that the carbon shin guards were thinner, they provided better protection due to superior material qualities. Francisco et al., 2000 covered their tibia model with butyl rubber material. The Load Cell-2 (at the back of the swing) was attached to the tip of an adjustable turnbuckle with a steel string. Adjustments were made with the turnbuckle. Three commercial polypropylene shin guards (Adidas Predator, Adidas UCL, and Nike Mercurial) and two custom-made carbon fiber shin guards were examined. Pediatric Rehabilitation, Electrophysiology, Orthotic and prosthetic applications, Prof., Marmara University, Physical Education and Sport Faculty, Turkey, National Library of Medicine The maximum kinetic energy in football collisions has been roughly estimated as 680 Nm (Gainor et al., 1978), which may be sufficient to result in a fracture (Winston et al., 2007). Football Shin Guard Socks+Shin Pads Sleeves Mesh Breathable. When comparing for mean force, peak force and impulse, both carbon fiber shin guards performed better than the commercial ones (Adidas Predator, Adidas UCL, and Nike Mercurial) (p = 0.000). In the high impact force trials, only 5.16-10.90 % of the load was transmitted to the sensors. These data were obtained from players who wore standard shin guards meeting the requirements of the BS-EN 13061. Access exclusive offers & shop the very latest products on the move. Standard shin guards may not be able to protect against HIF, because a considerable load of 276 N was transmitted onto the tibia, Football tackles can create much higher forces than those tested in this study. For the best experience on our site, be sure to turn on Javascript in your browser. It has been reported that fractures occurred even though shin guards were used (Ankrah and Mills, 2003; Boden at al., 1999). In HIF trials only neoprene-lined shin guards were used. Shin guard tests should be designed to simulate the high kinetic energy impacts observed in football. The artificial tibia models were tested under impact forces within the 2850-3000 N range.

The load transmitted onto the front of the tibia in both levels of impact was significantly below the predicted load level required to fracture the tibia. Accessibility In this study, two Adidas (Predator-AP and Adidas UCL-AC) and one Nike (Mercurial-NM) shin guards as well as two custom-made carbon fiber shin guards were tested (Table 1). This demonstrates that 5.16-10.90% of the loads were transmitted to the front of the tibia (i.e., 94.84-89.10% of them were absorbed). Special carbon shin guards were produced for the study. But apart from Ankrah and Mills, 2003 and Francisco et al., 2000, impact duration has not been considered. After the pre-test, measurements were started with the right shin guards of all models. The left shin guards of all models were tested to check reliability. Blocking some types of cookies may impact your experience of the site and the services we are able to offer. B) Graphic of maximal force. A balance adjustment was made before each impact with the relevant software for both of the load cells. Values are p <. Their main function is to protect the soft tissues and bones in the lower extremities from external impact. TheMatikz team havecome up with the perfect solution. LIF trials and a comparison of the groups. The information does not usually directly identify you, but it can give you a more personalized web experience.

This study proved that impulse values and impact times decreased in trials when carbon fiber shin guards were used. For this reason, athletes prefer custom-made shin guards. The .gov means its official. The reason might be the comfort of a porous fabric in contact with the skin and a feeling of full contact compared to the EVA liner. Because of those limitations have also been noticed in other studies, artificial tibia models were preferred (Francisco et al., 2000; Ankrah and Mills, 2003). These cookies enable the website to provide enhanced functionality and personalisation. Problems with the sensor system (the load cells or the swing system) and shin guards were assessed. and transmitted securely. Simulation of the human foot using a prosthesis was an advantage of this testing apparatus. In the LIF trials, the carbon shin guards were tested with two different types of liner, a 3 mm-thick EVA liner and a neoprene fabric. The new PMC design is here! A special software compatible for the PCD Model 30 A was used. Similarly, no consensus exists on the impact forces required to produce soft tissue injuries such as contusions (Ankrah and Mills, 2003; Francisco et al., 2000). were checked. Post-hoc comparison of HIF trials. Post-hoc comparison of LIF trials. Values from Load Cell-2 were monitored to guarantee that the pre-tensioning of the impacts remained within a certain range.

Compression sleevespromoteblood flow circulationwhich can assist a players performance, muscle recovery and injury prevention. Introducing our. The https:// ensures that you are connecting to the For peak force and impulse, the carbon fiber shin guards provided better protection than all the others. Four (two right and two left samples) of these custom-made carbon shin guards were tested. But in the 2850-3000 N range, some cracks formed on the front of the tibias. Both the shell and the ridge of the lining of the Nike Mercurial model were thicker than those of the Adidas UCL, which resulted in a superior performance during the LIF trials. sharing sensitive information, make sure youre on a federal Some amount of the impact force generated is absorbed by the foot-cleat combination delivering the impact.

These cookies do not store any personally identifiable information. In the HIF impact trials the Carbon-2 (neoprene) shin guard provided better protection compared to the plastic counterparts, similar to the results of Ankrah and Mills, 2003 and Francisco et al., 2000. D3O is a smart, rate sensitive material - the stress vs. strain characteristics are dependent on the rate of loading. These findings are in agreement with those of Ankrah and Mills, 2003 and Francisco et al., 2000. Two load cells, one in the front (Load Cell-1; strain gauge-based, 50 Hz; CAS Corp., Korea) and one in the back (Load Cell-2; strain gauge-based, 50 Hz; CAS Corp., Korea), were placed on the. It is accepted that custom-made carbon fiber shin guards, as tested in this study have a better fitting between tibia and shin guard (Ekstrand and Gillquist, 1982). This Paris plaster model served as the master mold for the production of carbon shin guards. When the protection capabilities of the shin guards were compared, the carbon shin guards were more effective specially with the EVA liner. A) A view of maximal force distribution. If you do not allow these cookies, you will experience less targeted advertising. The fact that the carbon models proved to be superior to the other shin guards, both with regards to maximum force and impulse values, could be attributed to their more rigid material as well as to their custom-made design. Assoc. This might be because of a difference in the types or positioning of the sensors used. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work. The impacts started at 800 N, until 2850-3000 N no change was observed in the artificial carbon fiber tibias. Price and other details may vary based on product size and color. Nonetheless, in this study we used a sensor-sheet consisting of 0.6 sensors per cm2 covering the whole surface under the shin guard, whereas Ankrah and Mills, 2003 placed only seven sensors of 9.5 mm diameter. (1997), Epidemiology and outcome of tibial diaphyseal fractures in footballers, Templeton P.A., Farrar M.J., Williams H.R., Bruguera J., Smith R.M. Fractures represent 2-11% of all football injuries and lower extremity fractures account for 30-33% of all fractures (Cattermole et al., 1996). These cookies may be set through our site by our advertising partners. The structural characteristics of the materials used. In this study, in the HIF trials high forces were recorded from the sensors under the shin guards which demonstrate the risk of real football tackles. All calibration and balance checks were repeated each time the shin guard was changed. During these trials, soft tissue was not wrapped around the tibia and shin guards were not used (Loadcell-1 hit the midline of the tibia directly). In the post-hoc comparison, the maximum force and the impulse were significantly lower (p = 0.000) for the carbon shin guard than for the polypropylene ones (Table 5). The prosthetic knee joint was fixed to the steel structure in a flexion position of 45. The left carbon shin guards were used in the preparatory stage, and the right ones were used in the actual test. However, the fact that there was no significant difference between the Carbon-1 (EVA) and Carbon-2 (neoprene) models during the LIF trials does not imply that this effectiveness would continue during HIF trials. In the low impact force trials, only 2.79-9.63 % of the load was transmitted to the sensors. adidas X Speedportal Training Shin Guards. The findings of Francisco et al. Data are means (SD). We present to you, shin pads that stay in place. Although no fractures were observed, cracks occurred in front side of the artificial tibia similar to the results obtained in the study of Francisco et al., 2000. The Adidas UCL model had the highest impulse value during HIF trials, presumable this product tend to bend more easily. With the exception of the study of Ankrah and Mills, 2003, the absorbed forces reported in the literature are lower than our findings. In the post-hoc comparison, the maximum force and the impulse were significantly lower (p = 0.000) for both carbon shin guards (Table 3); there were no significant difference between the two carbon shin guards. Some of the most painful hits in Epee are on the shin, traditional shin guards are heavy and bulky but D3O is light weight and flexible.
