“…As found in earlier work (e.g., Seeley et al 15 ) the young adults in this experiment did not 224 demonstrate functional differences between the two limbs; but it is noteworthy that earlier Step length is the anterior-posterior displacement of one step; step time is the time to …”

To prescribe safer exercise routines for obese people it is important to understand the effects of changing gait cadence on biomechanical gait parameters. The aim of this study was to verify if changes in gait cadence during overground walking affect the ground reaction forces and in-shoe plantar pressures of normal-weight and obese participants differently.As a secondary aim, the ground reaction forces and plantar pressures between normalweight and obese participants were compared during both low and high gait cadences. We assessed ground reaction forces and in-shoe plantar pressures in 10 foot regions during low (70 steps/ minute) and high (120 steps/ minute) gait cadences in 17 obese adults and 17 gender-matched normal-weight participants during walking. Changes in gait cadence similarly affect ground reaction forces (p = .21) and plantar pressures (p = .47) of normal-weight and obese adults. Similar ground reaction force peaks were observed between groups in both gait cadences (p = .59). Statistically significant differences in plantar pressures (p < .001) were found between groups in both gait cadences. In conclusion, higher vertical and anterior-posterior ground reaction forces associated with higher plantar pressure peaks in the rearfoot and toe regions in obese individuals suggest that walking at high gait cadences demands more to the musculoskeletal system compared to low gait cadences.

“…4,12 The symmetry index has been used along with the assessment of functional asymmetry in gait kinematic and kinetic parameters, ground reaction force of gait and running. [13][14][15][16][17] This index defined by Robinson et al has been widely used to quantify symmetry and it has been found to be cheap, useful, and easily applicable and results are presented clearly.…”

A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The aim of this study was to investigate differences in plantar pressure characteristics between preferred and non-preferred foot in elite taekwondo athletes. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : The study population consisted of 11 elite taekwondo athletes ages ranged between 19.16±2.72 years. To determine preferred foot, they were also asked which leg they preferred to kick a ball. Plantar pressure distributions were measured by pedobarography device. The relative pressure-loads (%) between preferred and non-preferred foot determined with static pedobarographic measurements while subject stand on the pressure plate. The dynamic pedobarographic measurements were performed to investigate plantar pressure distribution, temporal characteristics and peak pressure asymmetry between preferred and non-preferred foot. R Re es su ul lt ts s: : There was no statistically difference between preferred and non-preferred foot with regard to static measurement results. No significant differences were found between foots for temporal characteristics and peak pressure underneath the ten anatomical areas. The absolute impulse underneath the second metatarsal was significantly higher at preferred foot while absolute impulse of lateral heel was higher at non-preferred foot. The relative impulse of second metatarsal and third metatarsal were also significantly higher at preferred foot. Peak pressure asymmetry was found in favor to non-preferred foot. C Co on nc cl lu us si io on n: : The finding of present study indicates that the peak pressure beneath the preferred and non-preferred foot is not symmetrical. Peak pressure asymmetry finding indicates that preferred and non-preferred foot should be assessed and trained separately to prevent sports injury in taekwondo.K Ke ey yw wo or rd ds s: : Foot symmetry; plantar pressure; symmetry index; taekwondo Ö ÖZ ZE ET T A Am ma aç ç: : Bu çalışmanın amacı elit tekvando sporcularında tercih edilen ve edilmeyen ayaktaki plantar basınç karakteristiklerinin farklılıklarını araştırmaktır.

Tercih edilen ayağın belirlenmesi için bireylere topa hangi ayakla vurdukları soruldu. Plantar basınç dağılımı pedobarografi cihazı ile ölçüldü. Tercih edilen ve edilmeyen ayağa olan basınç yüklenmesi (%) birey platform üzerinde statik olarak ayakta dururken belirlendi. Tercih edilen ve edilmeyen ayaktaki plantar basınç dağılımı, temporal karakteristikler ve pik basınç asimetrisini araştırmak için dinamik pedobarografik ölçümler gerçekleştirildi. B Bu ul lg gu ul la ar r: : Statik ölçüm sonuçlarına göre tercih edilen ve edilmeyen ayaklara olan yük dağılımı istatistiksel olarak farklı değildi. Ayaklar arasında, temporal karakteristikler ve on anatomik bölge altındaki pik basınçlar bakımından anlamlı farklılıklar bulunmadı.
