    Comparison of Heart Rate Variability Psychological Responses and Performance in Virtual and Real Archery
    Dal, N; Tok, S; Balikçi, I; Yilmaz, SE; Binboga, E
    BackgroundThis 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.MethodsTwenty-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.ResultsResults 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.ConclusionsConsequently, the results of the present study illustrated that VR, and real archery might lead to different autonomic response patterns in terms of vagal activity. image

    The effect of motivational climate and conscientiousness on athletes' maximal voluntary contraction level of biceps brachii muscle
    Tok, S; Dal, N; Dogan, E; Yaman, Ç; Binboga, E
    We investigated the effect of induced motivational climates (a mastery climate and a performance climate) on maximal voluntary contraction (MVC) level of the biceps brachii muscle. We also aimed to explore whether motivational orientations, together with conscientiousness, are associated with MVC level in mastery and performance climate conditions. The sample consisted of 53 college student athletes ranging in age from 20 to 26. Participants first completed the Task and Ego Orientation in Sport Questionnaire and items relating to conscientiousness from the Short Form of the Five Factor Personality Inventory. Then, during isometric elbow flexion, MVCs were measured in a neutral condition. Afterwards, participants were informed of their MVC levels measured in the neutral condition via biofeedback software, and randomly assigned to either the mastery or the performance condition. Participants in the mastery climate condition were instructed to exceed their own highest MVC level observed in the neutral condition. In contrast, participants in the performance climate condition were instructed to exceed an unrealistic MVC level described as the best ever recorded so far. Results indicated that percentage change in MVC differed significantly between the mastery and performance climate conditions. Specifically, while there was a 13.5% increase in MVC value in the performance climate condition, there was an 8.8% decrease in the mastery climate condition. Results also showed that regardless of motivational climate, the percentage change in MVC was unrelated to motivational orientations and conscientiousness.

    The Effects of Red Versus Blue Lights and Neuroticism on Voluntary Biceps Brachii Muscle Contraction
    Binboga, E; Tok, S; Munzuroglu, M; Canüzmez, AE; Dal, N
    This study investigated the effects of red and blue monochromatic lights and neuroticism on athletes' maximal isometric voluntary contraction (iMVC) level of the biceps brachii muscle. During elbow flexion, we measured iMVCs under a white light (control) condition and under red and blue light conditions. Under red light (vs. white and blue), participants demonstrated a greater iMVC level. Further, based on a median split of the athletes' scores on Tatar's Five Factor Personality Inventory, high and low neuroticism groups showed no red light differences, while, in the blue light condition, participants high in neuroticism increased the iMVC level by 4.04% and those low in neuroticism decreased iMVC level by 6.31%. Thus, the effect of colored light on athletes' motor output varied with individual personality differences in neuroticism.

    Autonomic Cardiac Activity Among Novice Archers During Baseline, Shooting, and Recovery
    Tok, S; Dal, N; Zekioglu, A; Çatikkas, F; Balikçi, I; Dogan, E
    Tok, S, Dal, N, Zekioglu, A, catikkas, F, Balikci, I, and Dogan, E. Autonomic cardiac activity among novice archers during baseline, shooting and recovery.J Strength Cond Res34(9): 2627-2635, 2020-In the present study, we aimed to investigate whether heart rate variability (HRV) of novice archers may vary during baseline, shooting, and recovery periods. In addition, we aimed to explore whether HRV may have different patterns between successful and less successful archers and man and woman archers. The sample consisted of 39 (12 woman) novice archers ranging in age from 21 to 27. Baseline HRV activity was measured in the first stage of the experiment. Then, participants shot 10 arrows, from 18 m to an 80 cm diameter target, whereas their HRV was measured. Lastly, HRV recovery response was measured immediately after shooting. HRV was represented as low frequency (LF), high frequency (HF), and LF/HF ratio. When considering the entire sample, repeated measures of analysis of variance (ANOVA) indicated that only HF power differed among baseline, shooting, and recovery periods [F(2, 76) = 6.90,p= 0.002, omega(2)= 0.15]. When the data partitioned, based on the median split of the shooting scores, repeated measures of ANOVA demonstrated that none of the HRV components differed in the less successful group from baseline to recovery. However, in the successful group, both LF [F(1.47, 30.98) = 4.75,p= 0.024, omega(2)= 0.18] and HF [F(1.54, 32.37) = 6.61,p= 0.007, omega(2)= 0.24] power significantly differed among baseline, shooting, and recovery. No differences were found between man and woman archers in terms of HRV indices. The results of the present study indicated that physical activities requiring the use of perceptual motor skills, in addition to physical qualities, may lead to different HRV responses. Moreover, coaches aiming to develop archers' shooting accuracy may take into account LF power measured during an arrow shooting session.

    The Influence of Trait Emotional Intelligence on Archers' Autonomic Cardiac Recovery Responses Immediately After a Shooting Session
    Dal, N
    The present study aimed to investigate the association between trait emotional intelligence and heart rate variability (HRV) recovery responses of archers immediately after a shooting session. The sample included 87 novice archers ranging in age from 18 to 26. Participants first completed Schutte Emotional Intelligence Inventory. Then, they shot 10 arrows from 18 m to an 80-cm diameter target in four minutes. Afterward, participants' HRV recovery responses were measured during a four-minute recovery period. In this study, HRV was represented in terms of low frequency (LF), high frequency (HF), and LF/HF ratio. Results indicated a significant relationship between emotional intelligence and HRV recovery responses. A regression model containing emotional intelligence sub-dimensions was able to explain a significant amount of variance in HRV frequency domain parameters. Besides, high emotional intelligence archers were found to have higher-level LF and HF power but a lower LF/HF ratio than their low emotional intelligence counterparts. Taken together, the results observed in the present study indicated that emotional intelligence might give rise to more adaptive HRV recovery responses following a demanding arrow shooting session.
