Abstract
The purpose of this article is to biomechanically simulate athlete's leg and compression garment to measure the pressure on a young athlete's leg in order to apply more optimal and uniform pressure distribution while providing a greater sense of comfort when wearing.
The body condition and body shape of the athlete are measured by anthropometric method. Although Using a CT scan of the athlete's body (athlete's limb) and the mechanical properties of the pressure garment (leggings) that made of elastane spacer fabric was simulated by finite element technique. The results of measuring the real pressure on the young athlete's foot were measured and compared by a kikuhime device. The values of pressure applied by the leg in the real state and simulation indicate a maximum error of 14/44 percent (Cross section below the knee and the point behind the leg), a minimum error of 8 percent (Cross section of the ankle and the front point of the leg). Despite the assumptions and sources of error in this simulation, the results show that measured pressure values in the simulation mode with the real mode with incredible accuracy

Abstract
Knowledge of the relationship between performance and range of motion, helping to design training programs, comply of individual with the needs of children is, therefore, The aim of research the relationship between some of the lower extremity range of motion and biomechanical parameters of the boys was performed. Hundred students in this study were randomly selected. After measuring the range of motion of lower extremity, test speed, power, balance and agility of the subjects were recorded. By descriptive statistics to determine the mean and standard deviation of the method of multiple correlations to assess the relationship between the selected range of motion and biomechanical parameters of subjects were used. Hip flexion by speed, hip abduction and knee flexion by balance and hip flexion, hyper adduction and ankle dorsi flexion significant positive correlation by the agility, the rate of hip and knee flexion by power a significant negative correlation and with other lower extremity range motion parameters showed a significant positive association. According to the research findings, seem to be characteristics of the children lower extremity range of motion and identify performance indicators for various athletic field, can be used.

Abstract
The aim of this study is the effect of one period core stability exercise with and without kinesio taping on biomechanical effective factors in lower cross syndrome on female. 36 female between 30 to 40 were randomly divided in to 3 groups (control, with taping and without taping).  each group consist 12 participant. To measure Pelvic slope, Hip and Knee ROM, Isometric strength of flexors and extensors, Abdominal muscle endurance, Flexibility of spine extensors, Endurance of core muscles, respectively was used Inclinometer, Goniometer, Dynamometer, Body flection test, Body straightening test and Planck test to the side. To evaluate research hypotheses, if there is a significant difference between them we was used analysis of covariance test and multiple comparison in averages with post hoc bonferroni test. The result of the survey indicate that  difference between taping and control groups were significant in pelvic slope, hamstring and rectus femoris flexibility, knee and hip flexors muscle strength )p≥0/05(. Difference between without taping and control groups were significant in pelvic slope, rectus femoris and spine extensors flexibility (p≥0/05(. Difference between with and with¬out taping groups were significant in hamstring and iliopsoas flexibility, knee flexors, hip flexors, extensors, adductors strength, core muscles endurance )p≥0/05(. The results show that training with taping has an effective role on reducing lower cross syndrome. So it is suggested that taping can be used as an non-aggressive and low-cost method at the same time with exercise.
