Comparison of plantar pressure distribution between the right and left foot and their correlation with height and weight at wrestlers
Raghad Memar, Shiva Noori,
Volume 14, Issue 12 (10-2016)
Abstract

Since, sports activities are likely to be changes in various parameters of plantar pressure distribution during walking to create, This study compared patterns of plantar pressure distribution between right and left feet and their relationship with anthropometric parameters. 10 elite wrestler with the average and standard deviation of age: 23.6±3.33 yrs, height: 173.5±7.67 cm and mass: 83.3±21.8 kg voluntarily participated as subjects in this study. EMED-AT2 System for plantar pressure analysis, of parametric statistical methods paired t-test to compare parameters between the right and left leg and also of the Pearson methods for investigating correlation between variables was used. The only in the contact area parameter between the right leg and left at 4th mask significant differences were found (p≤0.05, ES=0.03). Also positive and significant correlation between height and mass with all the parameters were found (p≤0.01, p≤0.05) and in the heel area the correlation between maximum force in the right foot with height (medial heel r2=0.45 ; lateral heel r2=0.68) and weight (medial heel r2=0.56 ; lateral heel r2=0.8) and in the left foot with height (lateral heel r2=0.53) and weight (lateral heel r2=0.55) was reversed. (p≤0.05). Considering the lack of significant differences in plantar pressure parameters between the right and left foot, it could be argued, in wrestling foot demand function is the same. Also this research confirmed the results previous study indicating the absence of dominant leg in wrestling.


Effect of taekwondo on plantar pressure distribution symmetry in dominant and none-dominant limb
S Entezari, R Memar, M Kakavand,
Volume 15, Issue 13 (9-2017)
Abstract
The aim of this study was the comparison of plantar pressure distribution, vertical ground reaction force and contact area between dominant and none-dominant limb in top-flight females taekwondo.10 healthy young top-flight females taekwondo were selected. plantar pressure ,vertical ground reaction force and contact area were evaluated by emed system .The obtained data were analyzed by paired -t test and Symmetry index significance difference in toes 3-5 contact area between dominant and none dominant limb In addition Symmetry index for each parameter indicate asymmetry between limbs. The most ground reaction force and plantar pressure applied on heel region and metatarsal 3-5 and the least ground reaction force and plantar pressure applied on toe 2and toes3-5 in both limb.

Effect of balance training on unstable platform with tilting, translation and combined motion on knee joint position sense in active young males
Karar Khajeh Nemat, Heydar Sadeghi, Ismaeil Ebrahimi Takamjani, Raghad Memar,

Abstract
Proprioception is essential for joint function and through which individual can detect body parts movement in space. Aim of present study is to investigate effect of balance training on unstable platform with tilting, translation and combined motion on knee joint position sense in active young males. 39 healthy active male divided in to three training and control (n=9) groups. Training on unstable platform with tilting motion group (n=10), Training on unstable platform with translating motion group (n=10) and combined training group (n=10) performed exercises program for 8 weeks, three times a week. Errors in repositioning of knee joint in 30, 45 and 60⁰ angles (active and passive) was measured by Biodex system 3, before and after training period. Data was analysed by using one-way ANOVA test (P≤0/05). Although after 8 weeks, active and passive errors in repositioning of knee joint in mentioned angles decreased in training groups but this difference was not significant (P≤0/05). Balance training on unstable platform alone cannot have a big effect on knee joint position sense in active young male.
