Abstract
The aim of this study was to determine the effect of secondary task relevant and non-relevant to the free throw basketball skill on the free throw accuracy of basketball skilled players in choking under pressure. Twenty right-handed female players (aged 18-30) each with at least three years of experience in basketball took part study after completing the Sport Competition Anxiety Test (SCAT), Annett Handedness Questionnaire (AHQ) and measuring their anthropometric characteristics. The study included two testing sessions with an interval of 2 days. In the first and second session (no-pressure and high pressure, respectively) participants warmed up and performed 10 free throws in three conditions: 1) free throw, 2) free throw with relevant secondary task, 3) free throw with non-relevant secondary task. Results showed that the secondary relevant and non-relevant tasks to free throw have effects on accuracy in no-pressure (P=0.012, P=0.001) and high pressure (P=0.001, P=0.018) conditions. Also, there was significant differences between relevant and non-relevant tasks effects on accuracy in high pressure situation (P=0.001).
Overall, it may be used the secondary relevant and non-relevant tasks in choking under pressure situations for reduction of pressure imposed on athletes. Also, properly designed secondary tasks for free throw may be used to increase the accuracy of skilled participants under the pressure situations.

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.
