The aim of this study was to evaluate the effect of quiet eye training on selective attention, gaze behavior and free throwing of basketball under stressful conditions. The statistical population of the present study was all youth basketball players who participated in competitions in Tehran province. According to the type and purpose of the study, the sample was ranging in age from 16 to 22 years. A total of 24 people were selected and randomly and equally divided into two groups of 12 people (quiet eye and control training group). The study included a pre-test, post-test, first retention, pressure test and second retention. In the pre-test phase, participants performed 10 free basketball throws and at the same time their gaze behavior and performance were recorded. The training phase consisted of 3 sessions based on Vickers quiet eye training. The first post-test and retention stages were similar to the pre-test with a difference of 24 hours from each other and the pressure test was performed 48 hours after the first retention and the second retention phase was performed 48 hours after the pressure test. To analyze the data, combined analysis of variance test and Benferoni follow-up test were used and independent t-test was used to compare the groups. The results showed that quiet eye training had a significant effect on selective attention, gaze behavior and free throw performance under stressful conditions

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.

Numerous studies have examined the effects of focus of attention and quiet eye on motor performance, however the effects of these two variables in different load of task are ambiguous. Therefore, the purpose of the present study was to investigate the effect of the internal and external focus of attention instructions on quiet eye and accuracy of dart-throwing in two intensity of the secondary task. participants were 20 novice persons in dart-throwing that selected by convenience sampling; and in four dual-task conditions of internal attention-without tone estimation, external attention-without tone estimation, internal attention-with tone estimation, and external attention-with tone estimation performed dart throwing in counterbalance form that at the same time their gaze data recorded by binoculars eye tracking system. The result of accuracy showed that participants in external rather than internal attention condition and low- intensity rather than high-intensity condition had less radial error. The result of quiet eye showed that only the main effect of the secondary task was significant that participants in high-intensity of the secondary task rather low had more quiet eye duration. These results highlight the importance of external focus of attention in low and high secondary task load conditions for dart-throwing performance and direct the future research to explore more deeply the role of the quiet eye and attentional focus effects in dart-throwing performance.
