One of the most important goals of any athlete is optimum performance during competitions, and biofeedback is one of the new and growing ways to improve athletes’ performance. This study investigated the effect of biofeedback exercises on some physiological factors and the performance of skilled archers.

The present study was a semi-experimental type with pre-test and post-test design and a control group. Twenty four young men with an average age of 22.5 years were purposefully recruited among the participants who attended national ranking archery competitions and randomly assigned to an experimental and a control group, each consisting of 12 participants. After the pre-test (archery performance test), the experimental group first attended 10 sessions of biofeedback training related to heart rate control and breathing control based on the training protocol and then attended 10 sessions of the same biofeedback exercises with skin conduction guidance. Both groups continued their routine archery exercises under the supervision of the researchers during this period. After completing 20 training sessions, the archery performance was taken again as the post-test with the same pre-test condition from both groups.

The results showed that the heart rate of the participants was higher in tension and stress conditions compared to the resting state (p < 0.05). Also, at the post-test, the experimental group showed a lower heart rate under stress conditions compared to the control group (p < 0.05). Moreover, the analysis of covariance showed that the performance of both groups improved compared to the pre-test, but the experimental group performed better than the control group (p < 0.05). 

According to the findings of this study, more attention should be given to biofeedback exercises, and it is suggested to emphasize its use along with other training protocols.

Having Control over performance is one of the most important factors for success in the shooting. Research had shown that the more information a person has about the function of their body, the better control they will have over it. This study aimed to determine the effect of heart rate biofeedback along with relaxation training on the performance and gaze behavior of shooters.

16 semi-skilled shooters with an average age of 18 to 40 years were selected using the available sampling method. Participants were homogeneously assigned to the training (heart rate biofeedback with abdominal relaxation training) and the control groups. Before and after the practice interventions, all participants performed 20 shots from a 10 meters distance, while shooting accuracy scores were measured by Scat software and their gaze behavior were measured by an eye tracking device. Then, participants of the experimental group performed 30 minutes of heart rate biofeedback and abdominal relaxation intervention for four weeks, and three sessions per week.

The results of two-way ANOVA showed that there was a significant difference in the shooting accuracy score of players’ performance, but there was no significant difference in the gaze behavior of shooters between intervention and control groups in the post-test compared to the pre-test.

Overall, biofeedback with relaxation training was able to improve the performance of semi-skilled shooters. However, there was no significant difference in the gaze behavior of shooters due to the improvement of the indicators of this variable.

The purpose of this study was to determine the effect of instruction intellectual biorhythm feedback on the movement Performance of the students were athletes and non-athletes. The case studies were selected in access style include 144 male and female student athletes and non- athletes with an average age of 21.5 years. They were divided in 2 groups of athletes and non- athletes and each of the groups under three different conditions biorhythm cycle (intellectual biorhythm peak, intellectual biorhythm Peak feedback, control) in pre-test and then randomly divided into 6 groups and Participated in 3 times in motor function test. The data were analyzed in pre-test by one-way analysis of variance (ANOVA) test and to comparing different groups by Mix ANOVA with repeated measure test on a plot (2*3*3) and to identify differences by Bonferroni post hoc tests in a significance level p

The aim of this research was to investigate the ability of arousal control in male and female athletes using mental imagery and biofeedback methods. Participants were 30 male and female athlete students of Tehran University (mean aged 23) who were assigned into two homogeneous groups based on Vividness of Movement Imagery Questionnaire 2. Participants were given acoustic biofeedback during three stages of pretest, posttest, and follow-up test while their scores in arousal indexes such as heart rate, body temperature, and galvanic skin response were recorded. In posttest, they were asked to mentally imagine their performance under competition circumstance and in follow-up test they had to attempt to lower their arousal level using deep breathing and acoustic biofeedback technique. Results of analysis of variance with repeated measures and independent t test indicated that there is a significant difference between groups mean scores in follow-up test in three indexes of heart rate, body temperature, and galvanic skin response (p≤0/05). This finding suggests that male students have higher ability in arousal control compared with female students.
