Background: Heart rate variability (HRV) as a non-invasive indicator measures the activity level of the autonomic nervous system. Exercise has significant positive effects in increasing HRV indicators, which ultimately leads to cardiovascular health. People with panic disorder (PD) generally have low HRV indices and are more exposed to cardiovascular risks. Aim: The aim of the present study is investigating the effect of 12 weeks of hiking training on HRV of women with PD. Materials and Methods: In this semi-experimental clinical trial, 18 women with PD with average panic scores (45.00±19.55) as determined by Albany Panic and Phobia Questionnaire (APPQ) in two training group (12 weeks of hiking training with 70% to 80% MHR, three sessions a week, each one an-hour, and control group (without any regular physical activity) participated randomly. HRV of subjects was measured by Holter monitoring device (with 7 leads VX3+ SN 17570 made in USA) while resting and lying back for 20 min before and after 12 weeks. Results: The results of covariance analysis showed that panic scores (P≤0.001) and HRV factors including: SDNN (P≤0.05), SDNN index (P≤ 0.01) and TP (P≤0.03) of the subjects in the training group improved significantly but HF, LF, LF/HF, did not show significant changes (P≥0.05). Conclusion: It seems that 12 weeks of hiking training improves some of the HRV indices of women, which prevents the risk of cardiovascular diseases, and also reduces the symptoms of panic in women.

Background: Identifying the practice conditions that optimize the learning of motor skills is one of the main objectives in the area of human motor learning research. Aim: The present study aims to explore the effect of success criteria in high-error practice conditions on motor learning, self-efficacy, and mood states among female students. Materials and Methods: This practical quasi-experimental study was conducted in a field setting. The participants were 30 female students from Yazd University, selected through convenience sampling. Completing the consent form, the selected participants were randomly divided into three groups: high-error practice with a large target (n= 10), high-error practice with a small target (n= 10), and a high-error control group (n= 10). Then, mixed ANOVA was applied in order to test the hypotheses. Results: The results revealed that both of the large and small target groups significantly outperformed the control group regarding the difference in performance accuracy. Moreover, considering mood states, in the small target group, significant differences were observed in the calmness, happiness, and total mood state subscales, while in the large target group, significant differences were found in the vigor, happiness, depression, and total mood state subscales. In terms of self-efficacy, significant differences were observed in the level and power dimensions in small target group; however, the power dimension was the mere aspect revealing significant difference in the large target group. Conclusion: The use of success criteria in high-error practice methods is beneficial, and it is recommended to adopt this approach to improve accuracy and stability in the practice sessions.

This study aimed to investigate the impact of swimming training on negative emotional states in male university students. Male university students aged 18 to 25 were randomly assigned to either an experimental group (15 people) or a control group (15 people). Negative emotional states were tested using the depression, anxiety, and stress scales (DASS) (Lovibond and Lovibond, 1995). Differences over time between the experimental and control groups were assessed by 2×2 (group by time) repeated-measures analysis of variance. The mean scores of depression, anxiety, and stress significantly improved post-intervention in both groups, but the level of significance was higher in the experimental group. Therefore, it can be said that swimming training had a significant impact on improving negative emotional states in male university students. So, swimming training and the use of physical and sports activities for young people can help to improve and reduce the level of negative emotional states such as depression, anxiety, and stress in these people and even strengthen positive emotions in them.

Athletes are more at risk of developing anxiety disorders, depression, and substance abuse disorders due to facing unique stresses such as balancing social life with sports and high public expectations. The cognitive-behavioral therapy model, in addition to helping athletic performance, can play a preventive role in the development of psychological disorders. This study aimed to determine the impact of the cognitive-behavioral therapy model (with an emphasis on the role of the technique of using others as a benchmark for belief modification) on depression and return to sports in an athlete with major depressive disorder. In this study, a 5-session cognitive-behavioral therapy intervention with an emphasis on the technique of using others as a benchmark for belief modification was conducted. The athlete's depression and anxiety were measured before the intervention, after the intervention, and at a 2-month follow-up stage. The results showed that the athlete progressed from severe depression and moderate anxiety in the pre-test stage to mild depression and anxiety in the follow-up stage, indicating the positive role of the cognitive-behavioral therapy model (with an emphasis on the technique of using others as a benchmark for belief modification) in reducing depression and anxiety in athletes. In the technique of using others as a benchmark for belief modification, the athlete looks at the adaptive beliefs of real successful individuals and distances themselves from their maladaptive beliefs. In other words, if athletes can realistically see and understand how to apply adaptive beliefs in other successful individuals who have been in similar or even much more difficult situations, they will take action to modify their maladapti
