“…Worobets and Wannop (2015) showed similar results in a study on a group of 20 basketball players. They found performance increases of 1.7% in a timed cutting drill when bending stiffness was increased by 50% (0.22 to 0.33 Nm/deg).…”

“…A major limitation in terms of establishing a standard testing method is the fact that access to testing equipment or funds to purchase testing equipment may not be universally accessible. Potential solutions to this issue may include a testing method that requires limited mechanical equipment or data acquisition hardware, such as the method used by Worobets and Wannop (2015) or the introduction of a control or sample shoe that is readily available and could be tested alongside all experimental test footwear, establishing a relationship between the various test methods and setups.…”

Forefoot bending stiffness is a footwear property that has recently been gaining interest despite previously receiving limited attention compared to other footwear characteristics. This review focuses on relevant research studies examining the influence of forefoot bending stiffness on reducing injury and optimizing performance. Discussion of the current limitations and need for future research within the realm of forefoot bending stiffness is also highlighted. By reducing the amount of metatarsophalangeal extension, increased bending stiffness could not only reduce injury risk (e.g. turf-toe), but also serve as a treatment for metatarsal stress fractures by offloading the metatarsals. However, there are surprisingly limited in-depth studies examining how altered forefoot bending stiffness influences injury. Many unknown factors still need to be studied including the appropriate magnitude of bending stiffness and the influence that altering forefoot bending stiffness may have on the injury risk of other joints such as the ankle and knee. Forefoot bending stiffness can influence performance; however, the exact mechanism remains unclear. Early studies focused on foot energetics, while recent studies have shown the importance of altering the movement of the centre of pressure under the foot and the gearing ratio at the ankle joint. There appears to be a specific amount of forefoot bending stiffness for optimal performance. Future research should focus on identifying the exact mechanism of performance improvement with modified bending stiffness to help determine how this optimal stiffness can be identified.

“…increments is a limitation of this study [22]. However, we specifically chose to use the Vertec to measure vertical jump height instead of a device with greater validity such as a force platform so that we could directly compare the results of this study with previous research that examined the effects of footwear bending stiffness on vertical jump height performance [8,9,23]. The results of this study are similar to those found by previous research which demonstrated that increasing the stiffness of shoes (via the use of a carbon fiber plate inserted into the shoe midsole, with a bending stiffness approximately five times greater than the control condition) resulted in a 1.7 cm increase in vertical jump height for a group of 25 male participants [8].…”

“…Previous research has demonstrated that increasing the stiffness of shoes (via the use of carbon fiber plates inserted into the shoe midsole) resulted in a 1.7 cm increase in vertical jump height for a group of 25 participants [8]. However, systematically increasing footwear stiffness was not found to have an effect on jump height in 20 recreational basketball players [9]. Sprint running performance in 34 high-level sprinters was improved by the use of carbon fiber plates inserted under the shoe sock liner in track spikes to increase forefoot bending stiffness [10].…”

Sports equipment such as athletic footwear is designed to prevent injury and/or improve performance. There is limited research about the effects of foot orthoses or shoe insoles on performance improvement via enhanced energetics. One possible solution to improve the energy storage and return of athletic footwear is to utilize a carbon fiber shoe insole (CFI) optimally tuned for the human body-footwear system. The purpose of this study was to examine the effects of a CFI on athletic performance. Thirty-four (15 males, 19 females) collegiate athletes performed a vertical jump, a pro agility test, and a 10-yard sprint while wearing normal athletic footwear and footwear incorporating a CFI. Vertical jump height was measured using a commercial Vertec device; pro agility test and 10-yard sprint times were measured using a laser timing system. The use of a CFI resulted in significant improvements in the vertical jump (+2.5%, p = 0.012) and the 10-yard sprint (+1.5%, p = 0.020), but not in the pro agility test. These results demonstrated a CFI can enhance speed/acceleration and power in collegiate athletes. Individual anatomical and biomechanical differences may influence the appropriate CFI stiffness required for each athlete to achieve maximal performance in sports involving running, jumping, and change-of-direction.

Análisis de la influencia de las zapatillas de clavos en el rendimiento de una prueba de 40 m en mujeres velocistasAnalysis of spikes shoe´s effects on the sprint performance of women sprintersAdrián Jiménez-Velayos, Juan García-López Universidad de León. EspañaLos objetivos de este trabajo han sido cuantificar el efecto del uso de zapatillas de clavos en el rendimiento de una carrera de 40 m en mujeres velocistas, segregando el efecto de los clavos y del peso, y la influencia de este tipo de calzado en los parámetros biomecánicos de la carrera. Participaron 9 mujeres velocistas de nivel regional y nacional, que realizaron tres carreras de 40 m usando aleatoriamente tres tipos de zapatillas (clavos, clavos lastradas y running). Los resultados mostraron que el rendimiento mejoró un 1.8% con las zapatillas de clavos respecto de las de running, de los cuales un 1.2% se debía a los clavos y un 0.6% a la diferencia de peso. Analizando las variables biomecánicas se vio que la frecuencia de zancada fue constante, la amplitud de zancada mostró una tendencia a aumentar, debido al efecto de los clavos, y el tiempo de contacto disminuyó, por un efecto combinado de los clavos y el peso. En conclusión, el rendimiento en la carrera de 40 m mejoró al utilizar zapatillas de clavos respecto a las de running, debiéndose un tercio de la mejora a la diferencia de peso, y el resto posiblemente a la amortiguación, rigidez y tracción (dos tercios). Futuros trabajos deben intentar separar el efecto de estas tres variables. The purposes were to analyze the shoes spikes' effects on the performance of women sprinters, separating between both spike and weight effects, and to analyze the influence of this type of footwear on biomechanical parameters of running. Nine female sprinters of regional and national levels participated. They performed three 40 m sprints, using three different types of footwear (spikes, weighted spikes and running shoes) in a randomized order. The performance improved 1.8% using spikes with respect to running shoes, which 1.2% was due to the spikes and 0.6% was due to the weight effects. Analyzing the biomechanical variables, the step rate remains constant while the step length increased due to the spikes' effect, and the contact time decrease due to a combined effect of the spikes and the weight. In conclusion, the performance of women sprinters improved about 2% with spikes shoes with respect to running shoes. One third of this improvement was due to the weight effect, and two third to the spikes effect. Future studies must try to identify the individual effect of these three variables.Key words: spikes; biomechanics; sprint; performance.
