The aim of this study was to comparison the effect of different core stability training on lower extremities strength among deaf children. 28 deaf students (aged: 8-14 yr) selected and randomly divided into 3 groups: dynamic core stability, static core stability and control. Training continue for 8 weeks and 3 session per each week. The protocol composed of: specific training for spinal column stability, breathing maneuver with multifidus contraction, using dynamic stability in different positions accompany by extremities movements and using swiss ball. Dynamometer device was used to measures the strength of core stabilizer muscles. Dependent t (pre and post comparison in each group) and one way Anova were used to analyze data. Level of significant was 0.05 and statistical calculations were used by SPSS (version 22). The results of this study show that dynamic and static core stability lead to significant changes in lower extremities strength (P≤0.05, t=2.2, t= 5.7, t= 4.8, t= 2.8, t= 3, t=7.4), but the differences between dynamic and static core stability training and control were not significantly (P≥0.05, f=0.74, f=1.4, f=0.13, f=0.46, f=0.18, f=0.24). It can be concluded that dynamic and static core stability training can be a benefit method to improve lower extremities strength in deaf children and this finding leads to decreasing risk and probable injuries.

As people get older some may experience reduced mobility and more physical challenges that can affect their quality of life negatively. The research focused on investigating how two different types of training programs sensori-motor and Otago affect the abilities, functional balance and overall well being of men.This study was semi-experimental. This research included 45 men aged 65 to 70 who were selected in an accessible and purposeful and then randomly divided into three groups.. With 15 individuals, in each group, for sensorimotor training group the Otago training group and a control group. Respective exercise groups underwent a total of 24 training sessions done in 8 weeks. To measure abilities and being impact effectively, in this study various assessment methods were used such as Short Physical Performance Battery (SPBB) tests together with time up and go (TUG) evaluations besides implementing SF36 quality of life survey questionnaire. ANOVA and paired sample t-tests were done for data analysis with a significance level set at p≤ 0.05 using SPSS software version 23. The outcomes showed a Significant different, in groups prior and post exercise experimental (p=0.001). Significant variations were noted in the test results when comparing the sensorimotor and Otago groups to the control group at a significance level of p=0.001 for inter group comparisons; whereas no notable variations were observed among the groups during the pre test phase.Both sensorimotor and Otago exercises effectively enhance physical performance, functional balance, and quality of life in elderly men. Since no significant difference was found between the two experimental groups, it can be concluded that either type of exercise can be beneficial for improving these aspects of

the present study investigates the prevalence of emotional abuse among professional athletes by their coach in Mashhad city of Iran. the current study is applied research, about 40 professional retired athletes have participated voluntarily in individual sports (swimming and martial arts) and team sports (handball and basketball). The semi-structured interviews were used to gather the data and descriptive statistics were used to analyze the data. the results have shown that about 70 percent of participants have experienced various emotional abuse by their coach over years of playing professional sports and the maximal statistics belonged to criticism and reproach variables but just a few of them had reacted to their coach emotional abuse that entailed concentration disorders, performance and motivation decline, and ability obtainment issues. the results have shown that a high percent of athletes have experienced emotional abuse by their coach that encompassed many psychological and performing damages. Therefore, it is needed to train athletes’ preventable and resistant methods and the way of conveying these offensive behaviors to officials in order to reduce the damages of applied emotional abuse at athletes.
