Data base of Cognitive functions and their relation to balance and agility in athletes from differents sports branches

Successful performance in each sport requires high ability in various features, including motor and perceptual-cognitive skills. This study aimed to compare the balance and agility in athletes from several sports branches to find out how cognitive functions relate to these parameters. Seventy-three individuals aged 18-30 were included in this prospective-descriptive study. In the assessment of cognition, Montreal Cognitive Assessment Scale, d2 Test of Attention, and a Bassin Anticipation Timer Device were used. While Prokin-TecnoBody was used to measure the balance skills, Illinois Agility Test (IAT) was used for agility. IAT times showed positive weak correlations with both the absolute error-score (AES) at 8mph (r=0.260, p=0.040) and mediolateral balance score (ML)(r=0.255, p=0.043). While there was a negative weak correlation between AES at 3mph and anteroposterior score of balance (r=-0.267, p=0.035), we found positive weak correlation between AES at 8mph and ML of balance (r=0.253, p=0.046). It was found that the IAT scores of the sedentary group were significantly lower than athletes (p=0.000). According to AES at 3mph, there were significant differences between tennis players and both sedentary and volleyball players (p=0.008, p=0.002, respectively). When the AES at 8mph compared, the only statistically significant difference was between tennis players and sedentary (p=0.008). In conclusion, this study shows how cognitive functions, particularly coincidence anticipation timing (CAT), correlate with essential physical performance factors like agility and balance across different sport branches, suggesting that improving cognitive skills could enhance overall athletic performance and inform mental training strategies in sports. It is recommended that future sports science research focus on enhancing CAT through targeted training programs.

Paradigm Shift in Sports Science: The IOT-Enhanced Agility-Pad for Athletic Performance Evaluation

This paper explores the development and implementation of an agility monitoring system, aiming to provide real-time assessment of an athlete's agility. The need for such technology to facilitate instant and remote agility assessment has become increasingly apparent in the field of sports science. Unfortunately, progress in this area has been relatively slow until the emergence of IoT (Internet of Things) technology, which presents a promising avenue for athlete agility monitoring through telemetering. The core of this innovative system consists of an agility pad and a real-time monitoring module, with communication facilitated by LabVIEW software. Our approach involves rigorous testing, including unit testing of the agility pad, which serves as an MQTT publisher, the server, which functions as an MQTT broker, and the monitoring module, acting as an MQTT subscriber. In addition to these technical aspects, this article showcases various outcomes of our research. These include the designs of two activity diagrams, a comprehensive conceptual framework for agility monitoring, the database structure, communication designs for the agility pad, a wiring schematic, a 3D model of the agility pad, and the corresponding wiring configuration. We have successfully constructed two sets of agility pads, each integrated with an MCU system (ESP8266) and a dedicated database architecture designed for agile monitoring. One significant achievement of our work is the identification of the optimal delay interval required on the agility pad to prevent data loss on the MQTT broker. Furthermore, we have effectively developed a mechanism for detecting and addressing abnormal data during each testing phase, which contributes to the robustness and reliability of the system. This paper not only highlights the innovative technology behind the IOT-Infused Agility-Pad but also underscores its potential to revolutionize the assessment of athletic performance, offering coaches and athletes real-time insights into agility progress.

Two reviewers independently performed study selection and assessed the quality of included studies using the Physiotherapy Evidence Database (PEDro) scale, and a third reviewer was consulted in case of disagreements. The quality of the studies was mixed. Core muscle training can be used to target balance and agility in athletes. Furthermore, core training of variable frequency, intensity, and type can be incorporated in athletic programs to improve balance and agility.

Correlation Between Heart Rate Variability and Agility Scores of Elite Badminton Players: A Pilot Study.

Introduction Heart rate variability (HRV) indexes the autonomic nervous system, and HRV values are found to be higher in elite badminton players. Since an athlete's agility has a direct influence on badminton sporting performance, this study will analyze the correlation between HRV and agility. Aim The study's primary aim is to analyze the correlation between HRV and agility scores of elite badminton players. Methodology Ten elite badminton players who are currently participating at the state and national levels were recruited for the study. The study's participants were aged between 18 and 21 years, had a body mass index (BMI) of less than 22.9 kg/m2, were currently training 10-12 sessions of badminton per week (120-180 minutes per session), and had no comorbidities, injuries, or illnesses. For a duration of 14 days, a cross-sectional study design was utilized to evaluate the badminton players. Participants were tested in two blocks; each block consisted of five days of HRV and agility testing (Southeast Missouri [SEMO] agility test) followed by a break for two days. Higher agility performance was reflected by a lower SEMO agility test score. Results Data were analyzed using IBM SPSS Statistics for Windows, Version 27.0 (IBM Corp.,Armonk, NY). HRV and agility scores had a negative correlation, as indicated by the two-tailed Spearman correlation analysis (rs(8) = -0.82, P < 0.01). Conclusions The results showed that HRV and agility scores are highly correlated in elite badminton players. The results indicate that higher HRV values lead to better agility performance.Future studies need to be conducted on a large scale to evaluate the correlation in a diverse population.

It is necessary to know more about the suitability of body composition needed for each sport that can improve performance in athletes. This study aimed to determine the relationship between BMI, speed, and agility among athletes. Methods: This study used a literature review design to discuss the relationship between BMI, speed, and agility among athletes based on secondary data from published literature on Google Scholar and PubMed. The inclusion criteria used include: journals describing correlation between the body mass index, speed, and agility among athletes, journals published between 2015-2023. The exclusion criteria used include: excluding other articles if there are duplicates, excluding abstracts, theses, and dissertations. Results: Based on the results of a review of five studies that discussed body mass index on speed and agility in athletes, it was found that four journals stated that there were significant relationships between BMI, agility, and speed, but there was one journal which found an insignificant relationship between BMI and agility for male athletes but it was significant for female athletes. Conclusion: Agility and speed in athletes have a relationship with each BMI category. Athletes who were in the underweight BMI category would have better agility and speed compared to athletes who were in the overweight.

A Simple and Valid Method to Calculate Wheelchair Frame Rotation Using One Wheel-Mounted IMU.

Wheelchair sports have been using Inertial Measurement Units (IMU) to measure mobility metrics during training, testing and competition. Presently, the most suitable solution to calculate wheelchair speed and frame rotation is the 3IMU method as there is uncertainty about the ability of a one wheel-mounted IMU (1IMU) approach to calculate wheelchair frame rotational kinematics. A new method for calculating wheelchair frame rotational kinematics using a single wheel-mounted IMU is presented and compared to a criterion measurement using a wheelchair-frame-mounted IMU. Goodness-of-fit statistics demonstrate very strong linear relationships between wheelchair frame angular velocity calculated from the wheel-mounted IMUs and a wheelchair-frame-mounted IMU. Root mean square error (RMSE), mean absolute error (MAE) and Bland-Altman analysis show very small differences between the wheelchair frame angular velocity calculated from the wheel-mounted IMUs and the wheelchair-frame-mounted IMU. This study has demonstrated a simple and accurate approach to estimating wheelchair frame rotation using one wheel-mounted IMU during an elite wheelchair athlete agility task. Future research is needed to reexamine and compare wheelchair mobility metrics determined using the 3IMU and 1IMU solutions using this new approach.

Evaluation of a Reactive Agility Assessment Device in Youth Football Players.

Hoffman, JR. Evaluation of a reactive agility assessment device in youth football players. J Strength Cond Res 34(12): 3311-3315, 2020-The purpose of this study was to examine the reliability and validity of the Blazepod reactive agility device on sport-specific movements in competitive youth football players. Thirty-one male athletes (16.7 ± 1.5 years; 179.4 ± 7.0 cm; 75.0 ± 21.0 kg), all members of a youth tackle football team, volunteered to participate in this study. Subjects performed 3 reactive agility drills (side shuffle reactive agility, 1-m reactive agility, and 3-m reactive agility) at least 72 hours apart. In addition, all subjects also performed 3 traditional agility exercises: proagility, T drill, and L drill. These sessions were part of the offseason conditioning program for the football team that involved sport-specific drills. All assessments occurred following a warm-up and conducted in the same order on each occasion. To assess the validity of the reactive agility drills, the head coach was asked to rank the football playing and agility ability of the players participating in the study. The intraclass correlation coefficient values indicated that all 3 reactive agility drills displayed excellent reliability (r's ranging from 0.833 to 0.884). The measurement error was smaller than the individual variability, indicating that measurement error had a very limited effect on the results. Subjective rankings for agility significantly correlated with each of the agility and reactive agility measurements. Results of this study indicate that the Blazepod reactive agility device is a reliable measure of reactive agility performance and are consistent with the coach's perception of the athlete's agility performance, thus demonstrating construct validity.

Validity and Reliability of a Test Battery to Assess Change of Directions with Ball Dribbling in Para-footballers with Cerebral Palsy.

The purpose of this study was to evaluate the content and construct validity and between-sessions reliability of four agility tests requiring ball dribbling in football players with cerebral palsy (CP) with implications for classification and training. A sample of 35 football players with CP from three different countries took part in the study. They performed four tests in two sessions 72 h apart: i) 20 m in a straight line, ii) forward slalom with short changes of direction, iii) forward slalom with wide changes of direction and iv) square course. The Kappa coefficient was used to test content validity, obtaining moderate to almost perfect agreement results. Construct validity was also demonstrated with very large to almost perfect correlations between tests and sessions. Good reliability was found using intra-class coefficients (>0.86), standard error of measurement (<10.8%) and Cronbach´s alpha (>0.86). The comparisons between CP profiles (i.e. sport classes) demonstrated that those with mild impairment performed faster, and those with impairment of ataxia and dyskinesia performed worse. The four tests could have applications in classification, but may also be applied by the CP football coaches to improve athlete agility and football skills.

MRI reveals menstrually-related muscle edema that negatively affects athletic agility in young women.

ContextAbout 10% of Japanese female athletes are afflicted by menstrually-related edema, mainly in the lower limbs, and, with few studies on this problem, the effect on performance remains unclear.ObjectiveTo quantitatively evaluate fluid retention in the calf in female students over their menstrual cycle using magnetic resonance imaging (MRI) and to determine the relationship of MRI changes and athletic performance.DesignThe menstrual cycle was divided into 5 phases: menstrual, follicular, ovulatory, early luteal, and late luteal with sampling done in either morning (AM) or afternoon (PM) sessions. At each phase, MRI of the calf (7:00–8:00, 14:00–16:00), body composition and hormones (7:00–8:00), and athletic performance (14:00–16:00) were evaluated.Participants13 adult healthy Japanese female students with eumenorrhea.ResultsEstradiol levels decreased significantly in the menstrual phase and the follicular phase compared to the early luteal phase (P = 0.001, P = 0.024 respectively). Menstrual phase estradiol levels were significantly lower compared to the ovulatory phase (P = 0.015), and the late luteal phase (P = 0.003). Progesterone levels decreased significantly in the menstrual phase and the follicular phase compared to the ovulatory phase (P = 0.012, P = 0.009 respectively), the early luteal phase (both P = 0.007), and the late luteal phase (P = 0.028, P = 0.029 respectively), and it along with a significant decrease in the ovulatory phase compared to the early luteal phase (P = 0.010). AM T2 signals were significantly lower in the menstrual phase compared to the ovulatory phase (P = 0.043) but not other phases. PM T2 signals increased significantly in the menstrual phase compared to the follicular phase (P = 0.003), ovulatory phase (P = 0.009), and the late luteal phase (P = 0.032), and the difference between the AM and PM values increased significantly in the menstrual phase compared to the other 4 phases (P<0.01). A negative correlation between fluid retention and agility was observed.ConclusionIn female students fluid retention during the menstrual phase could be a factor that influences athletic agility.

Inspiratory Muscle Performance is Significantly Related to Agility and Speed in Collegiate Tennis Players

The Illinois Agility Test (IAT) measures sport agility by combining multi-directional skills with sprints. The Test of Incremental Respiratory Endurance (TIRE) evaluates inspiratory muscle strength and endurance via Maximal Inspiratory Pressure (MIP) and Sustained Maximal Inspiratory Pressure (SMIP). The relationship between athletic agility and inspiratory muscle performance (IMP) is unclear. PURPOSE: To examine the association between IMP and IAT results of Collegiate Tennis Players (CTP). METHODS: IMP of 7 male CTP (mean ± SD age = 20.3 ± 0.8 years, height = 186.2 ± 3.4 cm, and weight = 77.7 ± 6.5 kg) and 8 female CTP (age = 20.9 ± 0.8 years, height = 168.9 ± 6.2 cm, and weight = 64.7 ± 6.5 kg) was assessed via TIRE with the best of 3–5 trials providing MIP [measured from residual volume (RV)] and SMIP (measured from RV to total lung capacity). The IAT was performed twice with a 10-min rest between trials. The first and last intervals of the IAT comprised sprints to and from cones set 10 m apart, while the second interval involved weaving back and forth through four cones placed 3.3 m apart. A custom mobile app and tablet were used to time each IAT interval. RESULTS: MIP and SMIP of men were significantly (p<.05) greater than women (134.5 ± 19.4 vs. 99.5 ± 35.3 cm H2O and 791.1 ± 193.9 vs. 471.7 ± 162.8 PTU, respectively). Men were significantly (p<.05) faster during all IAT intervals and had a significant (p<.05) negative correlation between MIP and last sprint times of both trials (r = - .77 and - .89, respectively). In women, significant (p<.05) negative correlations existed between weaving time and SMIP of the first trial (r = - .77) and MIP and SMIP of the second trial (r = - .93 and - .89, respectively). CONCLUSIONS: IMP was significantly correlated to IAT time in CTP but gender differences existed. The correlation between MIP and last sprints in men suggests that men depend on IMP for speed. MIP and SMIP were related to the weave interval in women suggesting that women depend more on IMP for agility. Stronger correlations existed between IMP and IAT during the second IAT trials suggesting that greater IMP provides less susceptibility to performance decrement associated with fatigue. Greater IMP may provide greater balance and contribute to greater agility in women and speed in men, resulting in improved performance in CTP.

System design and application for evaluation of blocking agility in volleyball

The agility T-test and countermovement jump test have long been used to examine the agility of athletes. However, for some sports, newer systems of evaluation are being designed for specific movements. The goal of this study was to design a blocking agility system and apply it to analyzing the efficiency of 6 weeks of plyometric training on volleyball players. A total of 26 male volleyball players in Taiwan participated in the study. The participants were divided into a plyometric training group and a control group. The agility T -test, countermovement jump test, and blocking agility test were used to examine the influence of plyometric training on the blocking agility of volleyball players. A single-factor analysis of covariance was applied to obtain the variables for the two groups. There was no significant difference between the groups on the agility T -test. On the countermovement jump test and blocking agility test, the plyometric training group performed significantly better than the control group. Also, the power values of blocking agility were higher than 90%, which demonstrated very good validity. The results of this study indicate that appropriate plyometric training can increase the rate of force development for vertical jumps and significantly enhance the combined agility of volleyball players in terms of lateral-movement speed and quickness, which enable players to rapidly perform blocking actions.
