Abstract
Focus of attention instruction has a great influence on performance and learning. The purpose of this study was to examine the predicted constrained action hypothesis in badminton backhand serv. 30 women student participants from physical education classes of University of Kharazmi are selected as sample. Participants are tested in probe task at different stage of serve after identifying base of reaction time, and level of attention demanding of different parts was measured. Then participants divided into two groups (internal and external focus of attention) and they are tested with their specific instruction again. The results revealed that first stage of serve has the most attention need (p<0/001), but there is not any difference between two groups and different serve stage in the effect of focus of attention type. Accordance with these results the constrained action hypothesis at discrete skills is not confirmed.

Abstract
Researchers have shown that visual motor skills can be improved by practicing visual skills for optimal motor performance during sport. The aim of this research was to study the effect of 6 visual training on vision functions skilled players in Badminton sport. The participants of this research were skilled badminton players from Esfahan province. 60 persons (range of age: of 25-30) were divided into two group: experimental group and control group randomly. After the presence of the two groups in pre-test, the experimental group participated in visual training and control group in watching badminton match movie, both for six weeks and three sessions per week and in the last session, both groups participated in post-test. These tests included close-far chart test (hart chart), two rows Saccades test, and test of bringing closes a pencil (prism test), coordination of eye-hand test, and the time of vision reaction test. The data was analyzed by ANCOVA analyses test (p≤0.05).The results indicated that in some visual function (included Visual reaction time, Tracking and Visual concentration in experimental group was better than control group.

Abstract
How the process of acquiring and learning new motor skills can be enhanced is one of the basic questions in theoretical and applied movement science, rehabilitation and sport. The Differential Learning (DL) approach is mainly characterized by taking advantage, for the purpose of learning, of fluctuations that occur, without movement repetitions and without corrections during the skill acquisition process. The purpose of this study was to examine the effects of Differential Learning (DL) and Contextual Interference (CI) on the Retention and Transfer of Badminton backhand short serve. Prior to the implementation of the protocol, all participants of the pre-test were taken. Then, each group of research performed for 8 sessions according to the type of training. One day after the completion of the practice protocol, of all participants were taken the tests of Retention and Transfer. The analysis t-test indicated that there was a significant difference between the groups DL and CI in tests Retention and Transfer (p= 0.00). In fact, the results of the research show the effectiveness of the DL approach on the Retention and Transfer of Badminton backhand short serve. Based on the results of the research, the conclusion is that the DL approach is useful for learning skills, and can discover adaptive solutions by creating oscillations in the individual and helped to improve and learning skills.

Abstract
Motor performance and optimization is one of the most important goals of sports science professionals. Vision skills affect athletic performance and the acquisition of motor skills, which can be improved by practice. The purpose of study was to investigate the effect of visual and skill training on visual and performance skills, retention and transfer of Badminton backhand short service. 20 female students were randomly divided into two groups of 10 combined and skill. Depending on their type of training, the groups performed visual and skill training for 6 weeks. Before and after training, visual and performance tests, retention and transfer of backhand short service were done by the participants. For data analysis, t-test and mixed ANOVA analysis were used with a significant level of 0.05. The analysis indicated that there was a significant difference between groups in visual skills (p =0.00). The combined group had a significant improvement in perfomance, retention and transfer of the service (p = 0.00). Also, checking the interactive effect of time and type of training showed that the combined group was more advanced than the skill group (p = 0.00). The results of this study show the combined effects of vision and sports more than the individual trainings of vision and sports, and according to the results of the study, it is suggested that visual training be included as a supplementary training program in the Badminton field exercise.
