Psychophysiological Responses to Competition and the Big Five Personality Traits: This study examines the relationship between psychophysiological arousal, cognitive anxiety, and personality traits in young taekwondo athletes. A total of 20 male and 10 female taekwondo athletes (mean age = 18.6 years; ± 1.8) volunteered for the study. The Five Factor Personality Inventory and the state scale of the Spielberger State-Trait Anxiety Inventory (STAI) were used to measure personality and cognitive state anxiety. Electrodermal activity (EDA) was measured twice, one day and approximately one hour prior to the competition, to determine psychophysiological arousal. Descriptive statistics, Pearson product-moment correlations, and stepwise regression were used to analyze the data. Several "Big Five" facets were related to the EDA delta scores that were measured both one day and one hour before the competition. Two stepwise regressions were conducted to examine whether personality traits could significantly predict both EDA delta scores. The final model, containing only neuroticism from the Big Five factors, can significantly explain the variations in the EDA delta scores measured one day before the competition. Agreeableness can significantly explain variations in the EDA delta scores measured one hour before the competition. No relationship was found between cognitive anxiety and the EDA delta scores measured one hour before the competition. In conclusion, personality traits, especially agreeableness and neuroticism, might be useful in understanding arousal responses to competition.

We aimed to investigate the effect of external load on the joint position sense (JPS) accuracy and its relation to the target jump height. The present study also aimed to explore the relationship between force sense (FS) and maximum voluntary isometric contraction (MVIC). Participants’ MVIC levels were determined during the 45-degree knee extension task. Then, participants were asked to execute a knee JPS task with external load (EL-JPS) and with no-load (EL-JPS). To assess jumping accuracy participants were instructed to jump with their 50% of maximum jump height. Results indicated that EL-JPS error values were lower than NL-JPS. EL-JPS was correlated to jumping errors. However, the relationship between NL-JPS and jumping errors was not significant. A significant correlation was found between MVIC and FS errors.

Sports and exercise settings as well as other socio-cultural environments emphasize a thin and physically fit female body. However, there is a clear need for a better understanding of the physical and psychological correlates of social physique anxiety and body image dissatisfaction in female athletes. This study aimed to examine the association of the social physique anxiety, body image satisfaction, and personality with the anthropometric measurements in female college athletes according to their sport type using the Co-Plot technique. The sample included 63 female athletes ranging in age from 18 to 26. Results of the Co-Plot analysis revealed a significant association among social physique anxiety, personality and anthropometric measurements. This means that certain physical measurements may lead to greater social physique anxiety and body image dissatisfaction in female athletes. It was found that females having higher levels of social physique anxiety and thus, lower levels of body image satisfaction may be less emotionally stable and more negatively perfectionist. In conclusion, the results of the present study provided evidence to the claim that both physical self-perception and anthropometric measurements may be closely associated with psychological criteria in female athletes.

Background: This study examines the psychophysiological differences between virtual reality (VR) and real archery. It explores whether VR archery induces heart rate (HR), heart rate variability (HRV), and breathing rates similar to those experienced in real archery. Additionally, the study assesses differences in perceived anxiety, difficulty, confidence, rate of perceived exertion (RPE), and shooting performance between the two modalities, providing insights into the efficacy of VR as a training tool for archery.Methods: Twenty‐two (women: 8) individuals aged 20–24 participated in the study. We first recorded individuals’ resting HR, HRV, and breathing rates during baseline. Afterward, participants shot 10 real and virtual arrows from 18 m, whereas their HR, HRV, and breathing rate were measured, each lasting 4 min. Performance in VR and real archery was determined separately as the sum of the shots. We performed paired sample t‐tests to compare individuals’ performance, psychological, and psychophysiological responses recorded during VR and real arrow shooting. Afterward, we compared percentage changes between VR and real archery.Results: Results showed that HR and root mean square of successive differences (RMMSD) were significantly higher during real archery compared to virtual archery. In addition, VR archery led to a greater percentage change in RMSSD compared to real archery. Participants reported greater RPE and perceived difficulty after real archery. Performance was also higher during VR archery than real archery.Conclusions: Consequently, the results of the present study illustrated that VR, and real archery might lead to different autonomic response patterns in terms of vagal activity.

Objective: In the present study we aimed to examine the relationship between competitive anxiety, autonomic nervous system activity represented by Heart Rate Variability (HRV) and respiration, and performance in novice archers. We also interested in whether neuroticism may be a factor with a potential to moderate the link among anxiety, autonomic activity and archers' performance. Methods: The sample included 39 novice archers ranging in age from 18 to 27. Participants first completed to anxiety and neuroticism measures. Then, participants' HRV and respiration activity was measured for 4 minutes. Afterwards, participants shot 10 arrows from 18 m to an 80 cm diameter target while their HRV and respiration was measured. Shooting accuracy was determined in terms of radial distance (error) from the center of the target. To determine an overall performance score, the median value of the 10 arrows was calculated for each participant. Spearman correlation analyses together with linear regression were used to analyze obtained data set. Results: Overall, results indicated an association between respiration and anxiety. Moreover, results provided preliminary evidence that neuroticism may be a factor having potential to moderate the relationship between anxiety and autonomic activity before and during an archery competition. Discussion: Results of the present study suggested that determination of archers' performance should be based upon both physiological and psychological factors.
