Reaction Time In Athletes Research Articles

The superior response speed of table tennis players is associated with proactive inhibitory control.

ObjectiveTo explore the mechanism behind the faster volitional reaction time (RT) of open skill sports athletes from the perspective of proactive inhibitory control, with the hypothesis that the superior response speed of athletes from open skill sports is related to their enhanced capacity for releasing inhibition.MethodsParticipants were divided into two groups, an experimental group of 27 table tennis players and a control group of 27 non-athletes. By manipulating cue–target onset asynchrony (CTOA) in a simple cue-target detection task, the timing of target presentation occurred in different phases of the disinhibition process. The time needed for disinhibition were compared between groups.ResultsFor the experimental group, RT varied with CTOA at delays less than 200 ms; for CTOAs greater than 200 ms, RTs were not significantly different. For the control group, RT varied with CTOA for delays as long as 300 ms.ConclusionsTable tennis players took less time (200 ms) than non-athletes (300 ms) to complete the disinhibition process, which might partly explain their rapid response speed measured in unpredictable contexts.SignificanceThe study provided evidence for disinhibition speed as a new index to assess the capacity of proactive inhibitory control, and provided a new perspective to explore the superior RT of athletes from open skill sports. We also offered support for the fundamental cognitive benefits of table tennis training.

THE REACTION SPEED OF SPORTS ATHLETES IN DIFFERENT STATE LEVELS

ABSTRACT Introduction: The start of a sprint race is one of its most important stages. The reaction time at the start lays a psychological foundation for normal performance and performance improvement in its next three stages. Objective: To research the reaction time of athletes in the starting stage of the 100-meters sprint race. This helps analyze the internal reaction mechanism of the body, which receives signals and responds to actions. Methods: We use a bibliographical research, experimental comparison, and mathematical statistics to study the starting reaction time of sprinters. Results: The starting reaction time of male and female sprinters was basically at the same level. Conclusion: The starting time of Chinese sprinters needs to be improved. 400-m sprinters, especially, should devote more training to their starting reaction time. Level of evidence II; Therapeutic studies - investigation of treatment results.

COMPARISON OF SIMPLE VISUAL AND AUDIOTORY REACTION TIMES OF MARTIAL ARTS ATHLETES

<p>Many fitness skills are required to be successful in martial arts sports. It is known that the reaction time is distinctive for performance in all martial arts, although the specific importance of different motoric features in sports branches is variable. The aim of this study is to compare simple visual and auditory reaction times of martial arts athletes. For this purpose, 48 male athletes between the ages of 15 and 25 who have been actively doing sports for at least 1 year in boxing, judo, karate, muay thai, kickboxing and taekwondo branches were voluntarily included in the study. Height, body weight, simple visual and auditory reaction time measurements were made by obtaining the age and year of starting sports of the athletes. There was no statistically significant difference between the visual and auditory reaction times according to the participants' age, body mass index and sports age variables (p<0.05). There was a statistically significant difference between the visual reaction times according to the success level variable of the participants, but no significant difference was found between the auditory reaction times (p<0.05). In terms of the sport branch variable of the participants, a statistically significant difference was found between the visual and auditory reaction times (p<0.05). Accordingly, it can be said that the visual reaction times of the athletes improve as the level of success increases, and the visual and auditory reaction times are more important in martial arts athletes (muay thai, karate taekwondo, kickboxing and boxing) where quickness, movement frequency and movement speed are important. As a result, it is thought that martial arts athletes who want to increase their level of success should include reaction time studies in their training programs. However, it is suggested that it would be beneficial to apply such studies to larger groups and to include women.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0940/a.php" alt="Hit counter" /></p>

Comparison of Visual and Auditory Reaction Times in Athletes and Sedentary Individuals with Different Somatotypes: A Neuroperformance Study

Background: Body composition, which is affected by body fat ratio is an important factor affecting parameters such as strength, endurance, flexibility and agility required for superiority in sportive performance. Objectives: The aim of this study is to compare visual (VRT) and auditory (ART) reaction times of athletes and sedentary individuals with different somatotypes. Methods: The study included 148 individuals (73 athletes and 75 sedentary) with no symptoms. Somatotype character analysis was performed with Somatotype (1.2.6 trial) program using Heath-Carter formula after the determined anthropometric measurements were taken. Reaction time measurements were performed with Hubbard reaction meter. Results: Six different somatotypes were determined in both sedentary and athlete groups that participated in the study. In the comparison of VRT and ART scores of athletes and sedentary individuals in terms of each somatotype, statistically significant difference was found in VRT score in balanced ectomorph somatotype and in both VRT and ART scores of endomorphic mesomorph somatotype (P < 0.05). Conclusions: We think that regular training and sports shorten VRT and ART. We presume that these characteristics of athletes shorten their reaction times since sports events require more concentration. The results of our study are interesting in terms of being a new subject for scientists working in this field.

Does Anxiety Affect Neuropsychological Assessment in College Athletes?

Clinical Scenario: Anxiety is a mental disorder that affects a large portion of the population and may be problematic when evaluating brain injuries such as concussion. The reliance of cognitive testing in concussion protocols call for the examination of potential cognitive alterations commonly seen in athletes with anxiety. Focused Clinical Question: Does anxiety affect neuropsychological assessments in healthy college athletes? Summary of Key Findings: Three studies were included: 1 cross-sectional study and 2 prospective cohort studies. One study examined the effect of a range of psychological issues on concussion baseline testing in college athletes. Another study examined the effect of anxiety on reaction time both before and after sport competition in college-aged athletes. The final study examined the effects of psychosocial issues on reaction time during demanding tasks in college athletes. The first study reported slower simple and complex reaction times in athletes with anxiety. The second study found that athletes with high trait anxiety have slower reaction times both before and after competition. The third study reported that demanding tasks led to increased state anxiety which slowed reaction time. Overall, all 3 studies support the adverse effect anxiety can have on cognitive testing in athletes. Clinical Bottom Line: College athletes who present with anxiety at baseline may be susceptible to decreased performance on neuropsychological assessments. Strength of Recommendation: There is level B evidence that anxiety in healthy college athletes can impact neuropsychological assessments, and level C evidence that anxiety at baseline concussion assessment impacts neuropsychological testing in college athletes.

Visuo-oculomotor Function and Reaction Times in Athletes with and without Concussion.

Oculomotor tests in concussion commonly show impairment in smooth pursuit and saccadic function. Honing in on the systems likely to be affected by concussion will streamline use of oculomotor function as a supplemental diagnostic and prognostic tool, as well as improve our understanding of the pathophysiology of concussion. This study investigates oculomotor function between concussed and healthy collegiate athletes and determines measurement test-retest reliability of those tools. Eighty-seven healthy athletes were recruited from a U.S. Division 1 sports university and completed a 30-minute vestibular ocular testing battery in an enclosed rotary chair system equipped with 100-Hz eye-tracking goggles. Forty-three individuals completed the battery twice. Twenty-eight individuals with a current diagnosis of concussion also completed the battery. All participants were aged 18 to 24 years. Bivariate statistical tests examined differences in scores across groups, and intraclass coefficients were computed to test reliability. Concussed individuals had significantly longer saccadic, visual, and dual-task reaction times and reduced saccadic accuracy. There was no difference in optokinetic reflex gain, but few concussed individuals tolerated the task. Reaction time latencies and optokinetic gain show moderate test-retest reliability. Smooth pursuit tasks and saccadic accuracies showed poor test-retest reliability. Saccadic latency was the most sensitive oculomotor function to change after concussion and was reliable over time. Saccadic accuracy was significantly lower in the concussed group but had poor retest reliability. Optokinetic gain may warrant more investigation because of its high test-retest reliability and symptom provocation in concussion, despite not showing a significant difference between groups.

The Relationship Between Reaction Time and 60 m Performance in Elite Athletes

The aim of this study was to investigate the relationship between 60m sprint results and reaction times in athletes who took part in the World Indoor Athletics Championships. The reaction times and 60m sprint results were compiled for 483 sprinters (253 male, 230 female) who performed 60m sprint event. Corresponding data were obtained from archives of the official website of the International Association of Athletics Federation (IAAF). The relationship between reaction time and 60m sprint results were calculated using Pearson correlation coefficient. Additionally, the Independent Samples T-Test was used to compare athletes’ reaction times and 60m sprint results. Positive moderate correlation was found between mean values of all 60m sprint results and reaction times, which were analyzed together in all categories (r=.436, p&lt;0.01). Moreover, significant differences were also found between male and female finalists based on the 60m sprint times and reaction times respectively (t=-27.98, p&lt;0.01; t=-3.26, p&lt;0.01). As a result, it can be concluded that reaction time has great importance on 60 m performance. The best reaction time is related to the higher performance of 60m sprint in both male and female athletes. Moreover, this is also similar for round 1, semifinal and final categories. Coaches and athletes may consider improving reaction time to achieve better 60m performance.

Changes in Psychomotor Reactions and Hemodynamic Parameters during a Six Minute Walking Test for Men with Hearing Impairments

Background. Lately scientists abroad and in Lithuania have been interested in the peculiarities of motor learning and control. As the recent research shows, psychomotor parameters of persons with disabilities receive much attention from the community. However, we could find only a few scientific papers dealing with the psychomotor peculiarities of the disabled people, deaf people among. Research aim was to evaluate psychomotor reactions and hemodynamic indices of persons with hearing impairments, athletes and male persons who did not go in for sports.Methods. Twenty two young persons with hearing impairments took part in the study. Among them there were deaf players from the national basketball team (age 23.80 ± 2.6 years), (45.5%, n = 10). Persons with hearing impairments who did not go in for sports were in the control group (age 21.75 ± 1.8 years), (54.5%, n = 12). Research was carried out in the Lithuanian Sports University (LSU) using the analyser of dynamic parameters DPA – 1 for human hand and leg movements in the laboratory of motor control.Results. Simple and complex reaction time was statistically different only after physical exercise between athletes with hearing impairments and those who did not go in for sports (p &lt; 0.05). Simple psychomotor reaction time of athletes with inborn and acquired hearing impairments before and after exercise was not statistically significantly different. There were no significant changes in simple and complex reaction time and hemodynamic parameters (double product) of athletes with inborn hearing impairment after the 6-minute walking test.Conclusion. Simple and complex reaction time in athletes with hearing impairment and those who did not go in for sports was statistically different (p &lt; .05) only after physical strain in sportsmen. Having tested simple psychomotor time reaction in deaf persons since birth and those with the acquired hearing impairment before and after exercise we found that there was no significant difference ( p &gt; .05) between them, but the complex reaction time in subjects with acquired hearing impairment before and after exercise was shorter than in persons who were deaf since birth. However, the difference was also not significant (p &gt; .05). There were also no significant changes in simple and complex reaction time and hemodynamic parameters (double product) in athletes who were deaf since birth after the 6 min walking test.Keywords: hearing impairment, psychomotor parameters, reaction time.

RELIABILITY AND CRITERION VALIDITY OF A NOVEL CLINICAL TEST OF SIMPLE AND COMPLEX REACTION TIME IN ATHLETES.

Slowed reaction time (RT) represents both a risk factor for and a consequence of sport concussion. The purpose of this study was to determine the reliability and criterion validity of a novel clinical test of simple and complex RT, called RT(clin), in contact sport athletes. Both tasks were adapted from the well-known ruler drop test of RT and involve manually grasping a falling vertical shaft upon its release, with the complex task employing a go/no-go paradigm based on a light cue. In 46 healthy contact sport athletes (24 men; M = 16.3 yr., SD = 5.0; 22 women: M age = 15.0 yr., SD = 4.0) whose sports included soccer, ice hockey, American football, martial arts, wrestling, and lacrosse, the latency and accuracy of simple and complex RT(clin) had acceptable test-retest and inter-rater reliabilities and correlated with a computerized criterion standard, the Axon Computerized Cognitive Assessment Tool. Medium to large effect sizes were found. The novel RT(clin) tests have acceptable reliability and criterion validity for clinical use and hold promise as concussion assessment tools.

Comparison of two boxing training simulators

Summary Study aim: the aim of the study was to compare two methods for measuring punching and kicking force and the reaction time of athletes. Material and methods: both systems were designed to measure and to analyse the mechanical characteristics of punches and strikes delivered by upper and lower limbs to a punching bag. The main difference between both punching bags was the way in which the delivered force was measured. The first method used strain gauges while the second method used accelerometer technology. Both systems consisted of a punching bag with software, attached signal diodes, and either embedded accelerometers or strain gauges. The bags were of different sizes. Acceleration transducers and gyroscopes or strain gauges were placed inside the punching bags, which allowed for measuring dynamics while the bag was struck. The software calculated strike force, the point of force application and its direction, and reaction time. Both systems were tested. Results: the results of the accelerometer-based method show that the mean relative error of force calculation amounts to 3%. The measurement error of acceleration is less than 1%. The mean relative measurement error of the striking surface on the punching bag is 2%. However, the measurement error of force recorded with the strain gauge-based method is less than 1%. The results show that both systems are similar. Conclusions: the punching bag having an embedded accelerometer is equipped with more versatile software, which makes the system a good tool for practical application in combat sport training.

The Effect of a Long-Term Artistic Gymnastic Training on Reaction Time of Male Gymnasts

Since there are variations in the reaction times of athletes in different sports, the aim of the present study was to evaluate the effectiveness of a specific training program on a simple reaction time of male gymnasts. In this longitudinal study, fourteen adolescent gymnasts (mean age 12.6 ± 2.1 years) were randomly selected to work out for 15 months in the artistic group. Simple reaction time was assessed by visual and auditory tests using computer software. The training resulted in a significant (P < 0.001) reduction in visual (0.33 ± 0.047 s vs. 0.30 ± 0.048 s) and auditory reaction time (0.31 ± 0.056 s vs. 0.27 ± 0.038 s). This study suggested an improvement in both reaction time tests over a long time of specialized training program. Artistic gymnasts had overall developed results of the tests that might be derived from exercise induced arousal, concentration and movement complexity in this sport.

Sex Differences in Relations of Muscle Power, Lung Function, and Reaction Time in Athletes

In an earlier study, relations of nonverbal abilities with several bodily measures such as height, weight, and lung capacity were observed. The present aim was estimation of associations of muscle power and lung function with simple eye-hand reaction time. Sex differences for muscle power were significant even with the covariates of height, weight, and age included; however, these disappeared for lung functions (forced vital capacity and peak expiratory flow) and reaction time. The effects of leg power, forced vital capacity, and peak expiratory flow on the left eye-hand reaction time were significant after adjustment for height, weight, right- and left-hand powers and age. The positive effect of exercise may be especially associated with the right brain activity or left hand speed.
