* Multiple Comparisons, Tukey HSD.
The third artificial tibia was used only in the actual impact trials. (2000), Complications of tibial shaft soccer fractures, Winston R.C., Zain K., Susan D., William J.L. Assoc. The Nike Mercurial and the Adidas Predator models have an identical total thickness of 10 mm, but the outer shell of Nike Mercurial is 1 mm thicker. Another steel string was tied to the rear end of the turnbuckle and was connected to a table fixed to the floor, thus creating a special trigger mechanism. The protective properties of commonly used shin guards were compared with specially designed carbon ones. To generate comparable impacts, the pre-tensioning of the rig was calibrated by manipulating the turnbuckle. non significant. The Adidas UCL model had the highest impulse value during HIF trials, presumable this product tend to bend more easily. 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. 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. 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. From grassroots to the top leagues players have always had this annoying problem, the issue ofshin guards not staying put and consistently moving out of position during matches or practice.

In the low impact force trials, only 2.79-9.63 % of the load was transmitted to the sensors. 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. However, players wearing carbon shin guards, generally prefer neoprene liners. Although many authors advocate the use of shin guards, the ideal structural design characteristics have not been specifically defined. Carbon-1 (EVA) had to be excluded from the study during the HIF trials. (1985), Proceeding of Society of Automotive Engineers, 29th Stapp Car Crash Conference, Warrendale, PA, USA, The Proceeding of International Research Council on the Biomechanics of Injury Conference, Shaw A. D., Gustillo T., Court-Brown C.M. 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. D3O is a smart, rate sensitive material - the stress vs. strain characteristics are dependent on the rate of loading. Shin guard tests should be designed to simulate the high kinetic energy impacts observed in football. 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). Shin guard fixation, calibration of the load cells the estimated minimum duration between consecutive impacts, the adjustments required to ensure that the swing oscillates on a single axis, etc. The new PMC design is here! Just enter your postcode below to find your nearest store.
There is no consensus on the impact forces needed to produce a fracture. Problems with the sensor system (the load cells or the swing system) and shin guards were assessed. The .gov means its official. Three artificial tibias with natural anthropometric properties were produced similar to those used in previous studies (Francisco et al., Tibia midline anterior-posterior diameter: 45 mm, Tibia midline medial-lateral diameter: 38 mm. All calibration and balance checks were repeated each time the shin guard was changed. When comparing the maximum force and the impulse, significant differences were found between the shin guard models (p = 0.000).

These cookies are necessary for the website to function and cannot be switched off in our systems. Shin guards provide crucial protection against high kinetic energy impact as the anatomical structure of the shank possesses insufficient soft tissue on the medial surface and anterior border of the tibia. Football, carbon, force, prevention, shin guard, The biomechanics of soccer surfaces and equipment, Performance of football shin guards for direct stud impacts, Injuries in Football: Risk factors, injury mechanisms, team performance and prevention, Barrey P.B., John H.L., James A.N., William E.G.Jr. Otto Bock Lamination Resins (Otto Bock, 617H55 C-Orthocryl Lamination Resins) were used. 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. 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. For peak force and impulse, the carbon fiber shin guards provided better protection than all the others. 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. 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. Carbon shin guards provide sufficient protection against high impact forces. The site is secure. The structural characteristics of the materials used. In conclusion, it was observed that the carbon shin guards provided better protection at both levels of impact. All information these cookies collect is aggregated and therefore anonymous. The BS EN 13061 (British Standard European Norm) standard for shin guards aims to prevent lacerations, contusions and punctures but not tibia fractures, and these standards determine the protective clothing for players in all football associations.
The fact that the sensors were placed in similar positions might be the reason for the close results with the present study. Based on these same parameters, the Nike Mercurial provided better protection than the Adidas Predator and the Adidas UCL (p = 0.000). Their main function is to protect the soft tissues and bones in the lower extremities from external impact.
With this in mind, in this study the various forces transmitted to the front of the tibia under similar impacts were measured. For the best experience on our site, be sure to turn on Javascript in your browser. 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). 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. (1996), The frequency of muscle tightness and injuries in soccer players, The prevention of injuries in youth soccer. and transmitted securely. The difference between the impulse values of the commercial shin guards of comparable outer shells (PP) and padding material during the HIF trials can be attributed to the difference in designs. about navigating our updated article layout. Three commercial polypropylene shin guards (Adidas Predator, Adidas UCL, and Nike Mercurial) and two custom-made carbon fiber shin guards were examined. Francisco et al., 2000 covered their tibia model with butyl rubber material. Stay protected on the pitch and take your performance to the next level with our range of protective shin guards. Before Shin guards decrease the risk of serious injuries. One football cleat was put on the prosthetic foot. These data were obtained from players who wore standard shin guards meeting the requirements of the BS-EN 13061. The https:// ensures that you are connecting to the were checked. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. 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. 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). 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. A special sensor system (Tekscan, F-Socket system), 0.18 mm thick with 0.6 sensors per cm. Available in over 500 stores across the country, it's the perfect gift. 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. Absorbing impacts and keepin you comfy, check out the full shin guard collection below. 3) A multifunctional sensor system (Tekscan Corp., F-Socket System, Turkey) to record the impact on the tibia. This study proved that impulse values and impact times decreased in trials when carbon fiber shin guards were used. The Load Cell-2 (at the back of the swing) was attached to the tip of an adjustable turnbuckle with a steel string. For this purpose, three custom-made tibia models simulating natural anthropometric and mechanical characteristics were produced. Prof., Marmara University Medical Faculty, Department of Physical Therapy and Rehabilitation, Turkey. Some amount of the impact force generated is absorbed by the foot-cleat combination delivering the impact. Four (two right and two left samples) of these custom-made carbon shin guards were tested. The use of shin guards may not prevent fractures (Ankrah and Mills, 2003; Barrey, 1998). 2) An artificial tibia prepared by condensed foam and reinforced by carbon fibers protected with soft clothing. This website uses cookies. We use Strictly Necessary cookies to make our website work. An official website of the United States government. 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). TheMatikz team havecome up with the perfect solution. Commercially available Polypropylene based shin guards do not provide sufficient protection against high impact forces. We have been trailing this product for the last 6 months in our Fencing centre in London. The minimum and the maximum values measured by Load Cell-1 in the trials were not included in the statistical analysis. Price and other details may vary based on product size and color.

Studies reporting low impact velocities (Shaw et al., 1997) as well as high impact velocities (Boden et al., 1999); Templeton et al., 2000) that cause fractures are reported in the literature. The Exo Shin guard is powered by a revolutionary new material that is perfect for Epee fencers. Francisco et al., 2000, observed an average absorption rate of 11-17% with the use of shin guards. 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. In the high impact force trials, only 5.16-10.90 % of the load was transmitted to the sensors. The artificial tibia models were tested under impact forces within the 2850-3000 N range. The aim of this study was to compare the protective effectiveness of polypropylene based shin guards with custom-made carbon fiber ones. The prosthetic knee joint was fixed to the steel structure in a flexion position of 45. Post-hoc comparison of HIF trials. (1999), Tibia and fibula fractures in soccer players, Knee Surgery Sports Traumatology Arthroscopy, Bir C.A., Cassata S.J., Janda D.H. (1995), An analysis and comparison of soccer shin guards, Boden B.P., Lohnes J.H., Nunley J.A., Garret W.E. 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). Polypropylene shin guards bend more because of being plastic-based and forces acting on the tibia/soft tissue longer. Adjustments were made with the turnbuckle.

The dimensions of the test tibias used in the impact trials are as follows: In the LIF trials, 2.79-9.63 % of the load was transmitted to the sensors (Table 2). 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). But in the 2850-3000 N range, some cracks formed on the front of the tibias. 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). LIF trials and a comparison of the groups. will also be available for a limited time. Thus, a lower leg model capable of mimicking the surrounding soft tissues was developed (Francisco et al.. To facilitate the assembly of the components, the lower and upper ends of the artificial tibias prepared were not modeled to resemble the lower and upper ends of a natural tibia. Values are p <.

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. Learn more After the pre-test, measurements were started with the right shin guards of all models. FIFA the worlds governing body for football requires players to wear shin guards. But apart from Ankrah and Mills, 2003 and Francisco et al., 2000, impact duration has not been considered. 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). 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. Cattermole showed that damage on the shin guards occurred in 16,9% during a tackle (Cattermole, 1996). However, their possible role in soft tissue injuries could not be assessed.

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. To eliminate deformations of shin guards during trials, the repetitions for the impacts were limited to 13. This tension was set at 142.2 N for LIF trials and at 255.1 N for HIF trials. During high-energy impact trials, these three shin guards responded similarly even though there were differences in the thickness of the liner. Values from Load Cell-2 were monitored to guarantee that the pre-tensioning of the impacts remained within a certain range. Fractures represent 2-11% of all football injuries and lower extremity fractures account for 30-33% of all fractures (Cattermole et al., 1996). Using standard size shin guards do not always allow perfect fit and protection. nonsignificant. 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. * Multiple Comparisons, Tukey HSD. 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). PLEASE EXPECT MINOR DELAYS IN PROCESSING AND SHIPPING Due to the Xmas demand. (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. In the LIF trials the Nike Mercurial model was superior over the Adidas Predator and the Adidas UCL models, whereas in the HIF trials all three models behaved similarly. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work. government site. Although the rate appears to be low, the possibility of a maximum force of 262.41 N being transmitted to the front of the tibia demonstrates the risk that a player faces when receiving HIF impacts. 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. The impacts started at 800 N, until 2850-3000 N no change was observed in the artificial carbon fiber tibias. JavaScript seems to be disabled in your browser. 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).
