The aim of this study was to the effect Compare of soccer specific fatigue in different ambient temperatures (hot, cold and balance temperate) on balance and performance of soccer players with functional ankle instability.

The research method was half-experimental and applied. 20 young female soccer players, clubs Hamadan selected with functional ankle instability (FAI) right foot were. FAI was measured using 9 items Cumberland. Subjects like football, protocol Bangsbv was implemented in the winter (cold: temperature 10 degrees and relative humidity of 50 percent), autumn (moderate: ambient temperature 20 degrees and relative humidity of 50%) and summer (warm: the temperature 45 degrees and relative humidity 50 percent).Before and immediately after the completion of the protocol, tests, static balance (scoring errors test) and dynamic balance (Y test) and function tests (test jump Lee 3-test, Jump Bouncer 6 m at a time, test jump Lee crossover) of were recorded all subjects and the data. To analyze the data was used, t-test and one-way ANOVA and Tukey's test at the significant level 0/05.

The results showed that the effects of fatigue, especially football in cold, hot and Moderate ambient temperatures on the balance and performance of soccer players with FAI, were significantly different (p>0/05).

So that fatigue, especially football in hot and cold temperatures to moderate temperatures cause loss of balance and performance.

Hyper- kyphosis is one of the most common disorders among boys. Always, achieving to an appropriate corrective protocol has been considered. The aim of this study was to examine the effect of 12 weeks of combined training (movement therapy and Thai massage) on complication rate of thoracic kyphosis students with postural hyper-kyphosis.

The study design is semi-experimental and applicable by its aim and method was pretest-posttest with a control group. 40 students with hyper kyphosis of Yasouj city (20 students in the experimental group with an average age of 16/55 ± 1/19 year and 20 students in the control group with an average age of 16/65± 1/09 years) were randomly assigned to experimental and control groups. The experimental group received the treatment (corrective and Thai massage exercises for 60 minutes, three times a week) for 12 weeks, but thecontrol group received no treatment and was engaged in daily routine activities. Kyphosis angle was measured by the flexible ruler. The data were analyzed through Analysis of   T Independent and dependent at the significance level of P ≤ 0/05.

Independent t-test results showed that the angle of kyphosis of experimental group had significant improvement after 12 weeks of combined training (P < 0/001).  

According to the results of this study, combined training improved postural Kyphosis. Therefore, recommended to the healthcare professionals and corrective exercise experts that use of proposed protocol in conjunction with other treatments.

Given the importance of core stability exercises as well as the high prevalence of ankle sprains and functional instability and Subsequently, decrease of balance as a risk factor for the occurrence of an ankle sprain, core stability exercises aimed at stabilizing the central area of ​​the body can have a significant role in improving balance. Therefore, the purpose of this study is investigating the immediate effect of core stability exercises on static and dynamic balance in athletes suffered from functional ankle instability.

Thirty male college athletes suffered from functional ankle instability are participated in this study. After primary screening and identification of eligible athletes suffered from ankle joint functional assessment tool (AJFAT), subjects were divided into the experimental (n = 15) and control groups (n = 15). Athletes in the experimental group carried out two types of core stability exercises in a session. Static and dynamic balance measured in both the groups before and after the test.

Statistical test results showed that core stability exercises in short term period and in a single session improved the effect on static and dynamic balance in athletes suffered from functional ankle instability (p˂0/05).

It seems that muscle stabilizers of the core are important in controlling the proximal and distal joints for reducing the static and dynamic balance in athletes’ sufferd from functional ankle instability and doing these exercises in the short-term period can be useful in improving balance in athletes suffered from functional ankle instability. It is proposed to use the core stability muscles practice alongside ankle muscles in order to improve the athletes balance suffered from functional ankle instability.

Kabbady is one of the sports that has special place among the traditional sports. Due to the lack of research in this sport, knowing the components and physical parameters in the implementation of more effective and better techniques of this sport is important.  Therefore, the aim of this research was the comparison of core stability parameters in professional and amateur male kabbady athletes.

Due to limitation in the choice of subjects, subject consisted 40 male professional and amateur athletes with a history playing of minimum 6 seasons in kabbady participated in this study that respectively mean of age, height and weight were 24.62 and 22.33 yr. 174 and 171 cm ,75.75 and 65.16 kg. In this study, core resistance and core power tests were measured. Data were analyzed using by t student test (P˂0.05).

In all parameters of strength and core power between professional and amateur were statistically significant differences. (P˂0.05).

Due to the significant difference in core power and strength between the professional and amateur athletes in kabbady sport, it seems that these exercises is necessary to improve performance, in addition to other training programs.

Participation in sports activities always accompany with muscle-skeletal injuries among participations. One of factors that can reduce these injuries is proper balance ability. Maybe one of the factors which can affect to balance is the massage so the purpose of this study is to examine the immediate effect of massage in the lower extremities’ to static and dynamic balance in the collegiate athletic men.

The population of the present study is consisted of all the athletes of 18 to 28 years old of Tehran University. 30 athlete were selected and were randomly divided into control and experimental groups. Experimental group was placed under massage of limb lower for 10 minutes. The measuring of static balance by BESS, dynamic balance by Y test were done then. The paired-T test and independent-T were used to analyze the data (P≤0/05).

The results showed that there was a significant difference between the scores of balancing tests of BESS and Y in the experimental group after doing massage and using massage led to increased scores (P=0/01)

The result showed that using massage before competition lead to immediately improvement of static and dynamic balance of athletes. Regarding the study result, can use massage in order to improve balance of athletes and to prevent sports injuries subsequently before the competition.

This study aimed to compare the effect of two types of core stability and balance training program on the semi-dynamic balance of non-athlete girls.

This quasi-experimental pre and post-test on 36 healthy female student-athlete with a mean age 20/32+0/9 in three groups (11 people controls group, 12 people in central sustainability group, 13 people in equilibrium group) Was performed The subjects in the two groups practice their training program conducted 2 sessions per week for 4 weeks. Before and after the training period, semi dynamic balance of subjects were evaluated using the Biodex system. After collecting and importing data into environment of SPSS 20.0 software, using statistical methods, the Kolmogorov-Smirnov test for normality of the data and the analysis of variance the three groups were evaluated. ANOVA and Tukey's test was used to compare changes within the group and between groups

Compare the results of the test balance, represents a significant difference in the overall index and anterior posterior of non-athletic girls that this meaningful comparison of the group, in favor of sustainability is central.

According to the findings, it can be said that the core stability exercises appropriate method to enhance and improve balance. Hence it is necessary to develop a training program lasting central part of the semi-dynamic balance of functional (performance).
