A study protocol for a randomized controlled trial on the effect of Surya Nadi Pranayama practice on cognitive abilities in school children

Abstract Background Surya Nadi Pranayama is a yogic breathing technique that involves controlled breathing through the right nostril. The study aims to evaluate the effects of the 20-min practice of Surya Nadi pranayama (4 weeks) on cognition among schoolchildren, comparing it to observing a normal breathing pattern. Methods A randomized control study design will be adopted for this study with 100 school children with 12–16 years of age, will be recruited. Subjects will be randomly divided into the study and control groups. The study group will be advised to practice Surya Nadi Pranayama (n = 50), whereas the control group (n = 50) will be asked to relax in a sitting posture between 9 am and 10 am, Monday to Friday, for 20 min daily over 30 days. Results A baseline and post-intervention assessment will be performed for all the subjects a day before and after the intervention. The primary outcome measures are visual reaction time and auditory reaction time. The secondary outcome is critical flicker fusion frequency. Conclusion The potential benefits of this yogic breathing technique and the findings of this research may contribute to the development of interventions aimed at improving cognitive functioning in school-aged children. The study is prospectively registered in the Clinical Trial Registry of India (CTRI/2024/05/067441).

Novel cyclic homogeneous oscillation detection method for high accuracy and specific characterization of neural dynamics.

Determining the presence and frequency of neural oscillations is essential to understanding dynamic brain function. Traditional methods that detect peaks over 1/f noise within the power spectrum fail to distinguish between the fundamental frequency and harmonics of often highly non-sinusoidal neural oscillations. To overcome this limitation, we define fundamental criteria that characterize neural oscillations and introduce the cyclic homogeneous oscillation (CHO) detection method. We implemented these criteria based on an autocorrelation approach to determine an oscillation's fundamental frequency. We evaluated CHO by verifying its performance on simulated non-sinusoidal oscillatory bursts and validated its ability to determine the fundamental frequency of neural oscillations in electrocorticographic (ECoG), electroencephalographic (EEG), and stereoelectroencephalographic (SEEG) signals recorded from 27 human subjects. Our results demonstrate that CHO outperforms conventional techniques in accurately detecting oscillations. In summary, CHO demonstrates high precision and specificity in detecting neural oscillations in time and frequency domains. The method's specificity enables the detailed study of non-sinusoidal characteristics of oscillations, such as the degree of asymmetry and waveform of an oscillation. Furthermore, CHO can be applied to identify how neural oscillations govern interactions throughout the brain and to determine oscillatory biomarkers that index abnormal brain function.

The role of general cognitive skills in integrating visual and linguistic information during sentence comprehension: individual differences across the lifespan

Individuals exhibit massive variability in general cognitive skills that affect language processing. This variability is partly developmental. Here, we recruited a large sample of participants (N = 487), ranging from 9 to 90 years of age, and examined the involvement of nonverbal processing speed (assessed using visual and auditory reaction time tasks) and working memory (assessed using forward and backward Digit Span tasks) in a visual world task. Participants saw two objects on the screen and heard a sentence that referred to one of them. In half of the sentences, the target object could be predicted based on verb-selectional restrictions. We observed evidence for anticipatory processing on predictable compared to non-predictable trials. Visual and auditory processing speed had main effects on sentence comprehension and facilitated predictive processing, as evidenced by an interaction. We observed only weak evidence for the involvement of working memory in predictive sentence comprehension. Age had a nonlinear main effect (younger adults responded faster than children and older adults), but it did not differentially modulate predictive and non-predictive processing, nor did it modulate the involvement of processing speed and working memory. Our results contribute to delineating the cognitive skills that are involved in language-vision interactions.

How do visual, auditory and motor dual-tasking each affect swallowing and chewing function?

It can be challenging to perform a second task at the same time as swallowing. The study aimed to investigate the effect of visual, auditory and motor dual-tasking on swallowing and chewing function in healthy young adults. Right-handed healthy adults without any psychological and cognitive problems were included in the study. Swallowing was evaluated based on the dysphagia limit in different liquid textures such as water and nectar consistencies, and chewing was evaluated by the Test of Masticating and Swallowing Solids. For the second task, visual and auditory performance was assessed using reaction time, and the motor performance was assessed using a bilateral tapping task. Assessments were performed in two steps: baseline and dual-task. For baseline, all evaluation methods were applied individually. After completing the baseline assessment, dual-task assessment were carried out the following day. For dual-task assessment, the swallowing and chewing tasks were performed simultaneously with visual, auditory and motor tasks. Results showed a significant decrease in dysphagia limit in the nectar consistency, and significant increase in chewing time, visual reaction time and tapping rate (right-left) when compared to baseline and dual-task conditions (χ2(3) = 9.61, p = .02; χ2(3) = 9.02, p = .02; χ2(3) = 28.09, p < .001; χ2(3) = 28.97, p < .001; χ2(3) = 21.56, p < .001, respectively). However, there were no differences in dysphagia limit in the water and auditory reaction time compared to baseline and dual-task conditions (χ2(3) = 3.18, p = .36; χ2(3) = 2.56, p = .50, respectively). Results shedding light on how simultaneous dual tasks can influence swallowing and chewing. Dual-tasking cause a decrease in both swallowing/chewing and the visual/motor performances. These results may provide valuable information for designing interventions or strategies aimed at improving or maintaining optimal swallowing and chewing during in various populations during daily life.

Caffeine Improves Sprint Time in Simulated Freestyle Swimming Competition but Not the Vertical Jump in Female Swimmers.

Caffeine (CAF) has been shown to be an effective ergogenic aid in enhancing sports performance, including vertical jump (VJ), sprint, balance, agility, and freestyle swimming performance (FSP). However, whether acute CAF supplementation improves FSP in moderately trained female swimmers has not been well documented. Therefore, this study aimed to investigate the effects of CAF intake on vertical jump, balance, auditory reaction time (ART), and swimming performance in female swimmers. In a double-blind, cross-over design, eight moderately trained female swimmers (age: 21.3 ± 1.4 years, height: 161.2 ± 7.1 cm, body mass: 56.3 ± 6.7 kg, body mass index (BMI): 21.9 ± 1.3 kg/m2, and habitual CAF intake: 246.4 ± 111.4 mg/day) ingested caffeine (CAF) (6 mg/kg) or a placebo (PLA) 60 min before completing VJ, balance, ART, and 25/50 m FSP. CAF supplementation resulted in a significantly lower time both in 25m (p = 0.032) and 50m (p = 0.033) FSP. However, CAF resulted in no significant difference in VJ, ART, and RPE (p > 0.05). Balance test results showed a non-significant moderate main effect (d = 0.58). In conclusion, CAF seems to reduce time in short-distance swimming performances, which could be the determinant of success considering the total time of the race. Thus, we recommend coaches and practitioners incorporate CAF into swimmers' nutrition plans before competitions, which may meet the high performance demands.

An In-depth Analysis of Multisensory Reaction Time Disparities between Yogic and Non-Yogic Practitioners

Background. Auditory and visual reaction time refers to the duration between the introduction of a sound or light and the onset of a response. It is an important aspect of human behaviour, influencing performance in various activities ranging from daily tasks to sports and emergency situations. Objectives. The purpose of this study was to investigate reaction time (auditory and visual) as a component of skill-related fitness between male college students practicing yoga and those who do not. Materials and methods. A total of forty male college-going students (N = 40) were randomly selected to participate in this study. Out of the total, twenty participants (n = 20) were dedicated yoga practitioners actively involved in district and state-level yoga competitions. The remaining twenty individuals (n = 20) followed a sedentary lifestyle and were not involved in yoga practices. The subjectsʼ ages ranged from 17 to 25 years, encompassing a cohort of young adults. The data pertaining to visual reaction time (VRT) and auditory reaction time (ART) was collected using an audio-visual reaction timer. Each participant performed the task thrice, and the mean score was used to indicate the experimental reaction time in milliseconds (ms). Descriptive statistics and the independent samples t-test were subsequently conducted to evaluate the significance level, with a predetermined threshold set at p &lt; 0.05. Results. The results showed that the comparison between VRT and ART of yoga and non-yoga practitioners revealed that for yoga practitioners, t(38) = 2.91, and p &lt; .006, whereas for non-yoga practitioners, t(38) = 3.55, and p &lt; .001. Regarding VRT between yogic and non-yogic practitioners, t(38) = 1.99, and p &gt; .054, and for ART between yogic and non-yogic practitioners, t(38) = 2.12, and p &lt; .041. Conclusions. The findings suggest that both yogic and non-yogic practitioners demonstrated significantly lower level of ART compared to VRT. Further results indicate that hand speed in terms of VRT is nearly identical between yogic and non-yogic practitioners, but the ART of yogic practitioners was observed to be faster than that of non-yogic practitioners. Yoga has been associated with various physical and mental health benefits, and studies suggest that it may have a positive impact on reaction times.

A comparative study of simple reaction time in PCOS and non-PCOS patients and its relation with BMI

Introduction and Aim: Polycystic ovarian syndrome (PCOS) is a hormonal disorder of the female reproductive system causing infertility, an irregular menstrual cycle, and hormonal imbalance characterized by hyperandrogenism. Reaction to any stimulus is a voluntary response that measures the speed of response of a person. There is gender variation in reaction time, hence there is a need for evaluation of reaction time in PCOS. Thus, auditory and visual reaction time may be affected in the women with polycystic ovaries. The aim of the study was to compare ART and VRT in PCOS and non-PCOS Individuals and to correlate ART and VRT with BMI in PCOS individuals. Materials and Methods: Age-matched 25 normal and 25 PCOS were subjected to ART and VRT and recordings were obtained. The anthropological parameters like height, weight, and BMI were computed. The results were analyzed using a t-test and Pearson’s correlation test using SPSS software. Results: The auditory reaction time showed significant (p&lt;0.001) increase in PCOS 0.318±0.0388 than non-PCOS individuals 0.239±0.0629. There was positive correlation(r=0.491, p&lt;0.05) of BMI with visual reaction time in PCOS individuals. Conclusion: Since there is an increase in reaction time and a positive relation with BMI we can say that there is a decline in cognition in PCOS individuals probably due to hormonal changes and obesity.

Effect of Right Nostril Breathing on Cardiorespiratory Parameters and Reaction Time in Young, Healthy Humans: An Interventional Study.

Yogic breathing helps in reduction of stress and strain in the body. Right and left nostril breathings (RNB and LNB, respectively) have different effects on cardiorespiratory parameters. The study was performed to examine the effect of RNB exercise on cardiorespiratory parameters and reaction time in young, healthy human volunteers. In this prospective, interventional study, 110 young healthy volunteers underwent systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR), respiratory rate (RR), vital capacity (VC), peak expiratory flow rate (PEFR), and reaction time (RT) examination before and after 2 weeks of performing 45 min of RNB exercise daily. There was notable increment in SBP (113.39 ± 17.72 vs. 117.74 ± 10.83 mmHg, P = 0.002) and DBP (67.64 ± 10.32 vs. 71.27 ± 8.68 mmHg, P = 0.002). PR increased nonsignificantly (86.44 ± 12.65/min vs. 87.32 ± 13.43/min, P = 0.476). Significant decrease in RR (14.40 ± 2.48/min vs. 12.31 ± 2.23/min, P < 0.0001) was observed. VC (3.57 ± 0.57 vs. 3.82 ± 0.55 L/min, P < 0.0001) and PEFR (441.36 ± 50.22 vs. 468.91 ± 53.66 L/min, P < 0.0001) also increased significantly. Substantial reduction in auditory reaction time (ART) (165.58 ± 32.18 vs. 147.42 ± 23.39 ms, P < 0.0001) and visual reaction time (VRT) (191.04 ± 37.94 vs. 165.86 ± 28.74 ms, P < 0.0001) was seen. After engaging in cardiorespiratory exercise, the maximal heart rate (MHR) remained unchanged (P = 0.929). RNB results in increase in blood pressure, heart rate, VC, and PEFR and decrease in ART and VRT. Further studies in patients with cardiorespiratory diseases are necessary to understand its clinical utility.

The Investigation of the Effects of Short-Term Body Weight Loss on Elite Wrestlers on Anaerobic Performance and Reaction Time in Tournament Conditions

Athletes, who engage in wrestling, perform weight adjustment before the competitions like all weight loss category sports. For this reason, weight management is a very important factor prior to matches. When the studies on weight loss are examined, it is seen that athletes lose weight in a short time close to the competition. This study aimed to investigate the effects of short-term body weight loss in elite wrestlers on anaerobic performance and reaction time during tournament conditions. Ten experienced international level male wrestlers participated as a volunteer in this study. Participants lost 5% of their body weight within 48 hours, in 72 hours; 1 kg tolerance was given over 5% of body weight. During this process, body composition measurement, Wingate anaerobic performance test (WAnT), Countermovement Jump (CMJ), and visual and auditory reaction tests were conducted. In this study, a randomized crossover design was used and applications lasted four days. Two-way ANOVA with repeated measures was used for statistical analysis. Due to short-term body weight loss in body composition, total body water (TBW) and fat-free mass (FFM) were significantly reduced. In contrast, there was no statistically significant difference in body fat percentage (BF %), visual and auditory reaction time, CMJ and average power (AP). However, there was a significant increase was seen in Peak power (PP) and fatigue index (FI). The results indicate that 5% loss of body weight within 48 hours caused significant changes in body composition and negatively affected the fatigue index. For this reason, athletes who lose weight should avoid rapid weight-loss practices that will cause sudden changes in body composition in order to maintain their athletic performance.

Investigation of Visual and Auditory Reaction Times of Elite and Non-Elite Field Hockey Athletes

The aim of this study is to examine the visual and auditory reaction times of elite and non-elite hockey players. Between the ages of 19-29 33 elite male hockey players who selected to U21 national team of Türkiye and 37 non-elite hockey players who playing in the hockey super league and 1. league as a volunteer in the study. In the laboratory where age, height, body weight measurements and appropriate environmental and environmental conditions are provided to the groups. Firstly, the auditory reaction test was applied to the athletes, and then the visual reaction test was applied. Measurements were applied with online computerized programs (for visual reaction, www.humanbenchmark.com; for auditory reaction, www.cognitivefun.net).When statistical analysis of data is done; A significant difference was found in favor of non-elite athletes in the visual reaction test (p&amp;lt;0.05). In the auditory reaction test, a significant difference was found in favor of elite athletes (p&amp;lt;0.05). Consequently, a significant difference in favor of non-elite athletes in the visual reaction time test indicate that visual reaction time of non-elite athletes is better than elite athletes. a significant difference in favor of elite athletes in the auditory reaction time test indicate that auditory reaction time of elite athletes is better than non-elite athletes. In addition, it was concluded that the auditory reaction times of the elite and non-elite hockey players were better than the visual reaction times.

Effect of habitual breakfast skipping on information processing capacity, cortical response, and cognitive flexibility among medical collegiate- a cross-sectional study.

Breakfast replenishes glucose homeostasis and provides other micro-nutrients for the normal functioning of the body after a long night at night. Habitually skipping breakfast leads not only to metabolic disturbances but also to neurocognitive impairment. Hence, the current study wascarried out to study the effect of skipping breakfast on neurocognitive functions. A 9-item breakfast questionnaire was distributed online to students for identifying habitual breakfast skippers from non-skippers based on inclusion criteria. Random blood glucose was noted and visual and auditory reaction time, critical flicker fusion frequency, and Stroop test were assessed in both groups to assess cognition. Forty one habitual breakfast skippers who met the inclusion criteria showed increased visual reaction time, and auditory reaction time indicating cognitive impairment. A significant reduction in the Stroop test was observed among the non-skipper group when compared to the skipper group. This study suggests that skipping breakfast diminishes neurocognitive functions like problem-solving, planning, judgment, information retention, and reasoning.

Investigation of physical and cognitive performance profiles of 7-8 years old children in terms of talent selection in sports and sports orientation: the case of Kayseri

This study seeks to compare the physical and cognitive performances of 7-8-years-old children in terms of gender based on talent selection in sports and sports orientation as well as to contribute to the coaches studying in the field and the physical education teachers working in the schools in terms of talent selection tests and determination of talented athletes. The sample group consists of 178 boys and 151 girls studying in primary schools in Kayseri. To determine the physical performance of the participants, the eurofit test protocols including standing long jump, 30-m sprint test, sit-reach flexibility test, flamingo balance test, and 30 second sit-up test were applied. On the other hand, to determine the cognitive performance of the participants, visual and auditory reaction times were measured via the Newtest 1000 instrument. The SPSS 22 package program was used to evaluate the data. As a result of the statistical analysis, it was understood with the Kolmogorov-Smirnov test that the data showed normal distribution. The descriptive statistical method and the independent sample t-test were applied to the participants in inter-group comparisons. As a result of the descriptive statistical analyzes, the mean values ​​of the participants' anthropometric characteristics were found as (male, age; 7.30 ± .46 (years), height; 127.39±5.75 (cm), body weight; 28.84±5.93 (kg), BMI; 17.67±2.74) and (female, age; 7.27±.44 (years), height; 125.26±5 .19 (cm), body weight; 27.35±5.43 (kg), BMI; 17.36±2.79). As a result of the analysis, a statistically significant difference was found between the height values ​​of girls and boys in terms of anthropometric characteristics (p&lt;0.01). No significant difference was found in terms of other anthropometric values ​​(p&gt;0.05). In terms of physical performances, a significance at the level of (p&lt;0.01) was found in favour of boys in 30-m sprint test and standing long jump tests, and in favour of girls in flamingo balance test parameters. No significant difference was found in terms of cognitive performance. The results of the study reveal that the physical and cognitive performance data of primary-school 7-8-years-old children show similar developmental characteristics when evaluated in terms of gender.

HaptStarter: Designing haptic stimulus start system for deaf and hard of hearing sprinters

In this study, we design and develop HaptStarter—a haptic stimulus start system—to improve the starting performance of the deaf and hard of hearing (DHH) sprinters. A DHH person has a physical ability nearly equivalent to hearing; however, the difficulties in perceiving audio information lead to differences in their performance in sports. Furthermore, the visual reaction time is slower than the auditory reaction time (ART), while the haptic reaction time is equivalent to it. However, a light stimulus start system is increasingly being used in sprint races to aid DHH sprinters. In this study, we design a brand-new haptic stimulus start system for DHH sprinters; we also determine and leverage an optimum haptic stimulus interface. The proposed method has the potential to contribute toward the development of prototypes based on the universal design principle for everyone (DHH, blind and low-vision, and other disabled sprinters with wheelchairs or artificial arms or legs, etc.) by focusing on the overlapping area of sports and disability with human–computer interaction.

The Comparison of Reaction Times in Competing Karate Athletes

The aim of the research is to compare the reaction times of kata and kumite athletes participating in national and international competitions in karate. A total of 108 male competitive athletes, including 40 kata competition athletes between the ages of 18-32 and 68 kumite competition athletes between the ages of 18-29, participated in the research voluntarily. In the research, some physical characteristics of kata and kumite athletes and right-left hand visual and right-left hand auditory reaction time tests were performed. T-Test was applied to determine the difference between groups at the α=0.05 significance level in all independent groups. A statistically significant difference was detected in training age, height and right hand visual reactions (p&amp;lt;0.05) among male kata and kumite athletes participating in the competitions. It can be said that these differences are due to the differences in kata and kumite training methods.

Comparison of Visual and Auditory Reaction Times of Wrestlers Engaging in Traditional and Modern Wrestling

The aim of this study is to compare the visual and auditory reaction times of the athletes engaged in traditional wrestling and modern wrestling. Heavyweight athletes (n=22) who are involved in traditional wrestling such as oil wrestling, plaid aba wrestling, competitive aba wrestling, karakucak wrestling, short shalwar wrestling, and modern wrestling such as freestyle wrestling and Greco-Roman (n=24) wrestling were included in the study. Measurements were taken using the computer system (IRZ: cognitivefun.net) for visual and auditory reaction time. SPSS package program was used for statistical evaluation of the data obtained as a result of the study. As a result of the statistical evaluation, it was found that the average of visual reaction (fastest), visual reaction (slowest) and visual reaction (average) time of the wrestlers who are interested in modern wrestling compared to the wrestlers who are interested in traditional wrestling (p0.005), and the auditory reaction (slowest) and auditory reaction (average) time values were found to be significant between modern wrestlers and traditional wrestlers in favor of modern wrestlers (p

Detectıon of vısual-audıtory reactıon rates ın ındıvıduals wıth type 2 dıabetes mellıtus

AIM: The primary purpose of our study was to understand the damage in the peripheral nerves of patients with diabetes and to determine the change in patients’ reaction rates and perceptions by the age groups, duration of diabetes, fasting plasma glucose and HbA1c values, and compare these with those of the healthy individuals.METHODS: This study was carried out at the Baskent University Hospital Endocrinology and Metabolic Diseases Outpatient Clinic. A total of 64 patients diagnosed with type 2 diabetes and 64 healthy controls were included in the study. Finger tapping, visual, and auditory reaction time tests were performed on the subjects, respectively. The subjects’ fasting plasma glucose and HbA1c levels, and the duration of their diabetes were recorded. Analyses were performed using the SPSS version 25. Differences were considered statistically significant when the p-value is &lt;0.05.RESULTS: It was observed that the participants in the control group between the ages of 18-34 showed a faster reaction in all tests (p=0.01), but the difference in reaction rates in both groups decreased as the age increased. There were positive correlations between the duration of type 2 diabetes and the visual and auditory examination results (r= 0.69, p&lt;0.05, r=0.52, p&lt;0.05, respectively). There was also a positive correlation between the HbA1c (%) and the visual (r=0.97, p&lt;0.05) examination results.CONCLUSIONS: As the patients’ HbA1c levels and the time spent with type 2 diabetes increased, their reaction rate and perception skills decreased. Especially in the early stages of the disease, cognitive decline was observed to be rapid. It is thought that early diabetic control is significant.

Association of Personality Trait with Auditory and Visual Reaction Time among Young Healthy Subjects

Background: Personality traits along with well-known factors like socioeconomic status and cognitive ability, predict important life outcomes such as health and lifespan, educational and occupational attainment, and may promote specific types of task effectiveness, which occurs in part via the processing of information. Reaction time provides an indirect index of the central nervous system’s integrity and processing ability. Material and Methods: The 111 healthy subjects (aged 17 -23 years) interviewed to pre-designed proforma regarding socio-demographic profile, “Glazer-Stress Control Lifestyle” questionnaire for personality trait and reaction time recorded by “Audio-Visual reaction time apparatus”. Statistical analysis was done using IBM SPSS Statistics 20, and the P-value &lt;0.05 was considered significant. Results: The mean age of the study participants was 19.21±1.40 years, with a mean body mass index 20.65±4.32 kg/m2. Male subjects (68%) outnumbered the female participants (43%), and more than half of the subjects doing exercise. The nuclear family was the preferred mode of living belonging to class-II socioeconomic status (86%). The association of personality traits with auditory (low and high frequency) and visual (red and green light) reaction time was non-significant. Type-A personality subjects were maximum (13/20th), followed by Type-AB (6/20th) and least of Type-B personality (1/20th). Conclusion: The personality trait has no impact on auditory and visual reaction time. Though maximum participants belong to type A personality, still ambitious, proactive, and competitive nature does not influence the basic neurophysiological characteristics of the human body.
