Abstract
The current research is semi-experimental using a pre-test-post-test design with an intervention control group. For this purpose, 24 active volleyball players in the Southwest Tehran Volleyball Board were selected based on the entry criteria and were randomly divided into two experimental (N=12) and control (N=12) groups. In the experimental group, the subjects received a 60-70 minute session of the mindfulness program based on improving sports performance for six weeks. At this time, in the control group, in the same conditions as the experimental group, the chat program was conducted, including a review of the history, rules and some analyzes of volleyball. In the pre-test and post-test, measurements were taken of all the people present in the two experimental and control groups, including the mental performance and mental strength questionnaire, as well as the sports performance test in volleyball. To analyze the data, statistical tests of mixed analysis of variance and Anova and Bonferroni's post hoc test were used with SPSS software.
Findings: The results of mixed variance analysis in the variables of mental strength, smooth execution and performance showed that the main effect of the test (between pre-test and post-test stages) and also the effect of group interaction with the test were significant (p<0.05). No difference was observed between the experimental and control groups in the scores of mental strength, smooth performance and performance in the pre-test (p>0.05). However, in the post-test stage, a significant difference was observed in the research variables between the two groups (p<0.05).
