Introduction and Purpose: the current study was to examine the effect of quiet eye training on decision making, gaze behavior and tennis service skill learning.Methods: In this semi-experimental study, which was performed with a pre-test-post-test design with a 14-day follow-up period, 30 novices male tennis players of Isfahan House with an age range of 20 to 30 were selected and those located in quiet eye training and control groups. In the pre-test phase, the participants performed 12 tennis services, which also measured the participants' gaze behavior during the operation. Participants' service was also recorded by GoPro camera to measure decision making. In addition, participants' performance was recorded by the researcher. Then, the experimental group performed the desired exercises for 8 weeks, 3 sessions per week and 30 minutes per session. During this period, the control group performed their daily activities. At the end of 24 practice sessions, the post-test phase, and two weeks after the last session, the retention phase was performed as the pre-test phase. Data were analyzed by repeated measures analysis of variance.Results: The results showed that quiet eye training have a significant effect on improving decision making, increasing the length of the quiet eye period and increasing the performance of the tennis service (P <0.05).Conclusion: The results of this study support the pre programming hypothesis that the importance of planning and choosing the correct answer.

The purpose of current study was to muscle efficiency changes during successful and unsuccessful trials in elite pistol shooters with role of quiet eye meditation. In causal comparative study, 20 elite male pistol shooters selected for this study with age range 20-30 years old. After five trials familiarization, participants performed 20 trials to target with available standard. Scores of ten were considered successful, and scores of less than ten were considered unsuccessful. Data were analyzed using paired t-test and Bootstrap. The results indicated that there was significant difference between biceps and triceps muscle activity in successful and unsuccessful trials, and participants had lower muscle activity in successful trials than unsuccessful trials. Also, Bootstrap results revealed that the quiet eye period mediates biceps and triceps muscle activity in successful and unsuccessful trials. Overall, the results of current study confirmed postural stability hypothesis that this is the determining factor during this period is an increase in postural stability, which leads to a reduction in "noise" in the motor system.Shooting skills with high perceptual / cognitive requirements and low mobility needs and is one of the sports that is highly dependent on the performance of the visual system, because target identification and tracking is largely dependent on the performance of the visual system.In the present study, the researcher intends to investigate the muscular efficiency and mediating role of the length of the stationary eye period in the electrical activity of biceps and triceps of skilled pistol shooters in successful and unsuccessful attempts.
