Acute Sleep Deprivation Impairs Motor Inhibition in Table Tennis Athletes: An ERP Study

Excellent response inhibition is the basis for outstanding competitive athletic performance, and sleep may be an important factor affecting athletes’ response inhibition. This study investigates the effect of sleep deprivation on athletes’ response inhibition, and its differentiating effect on non-athlete controls’ performance, with the aim of helping athletes effectively improve their response inhibition ability through sleep pattern manipulation. Behavioral and event-related potential (ERP) data were collected from 36 participants (16 table tennis athletes and 20 general college students) after 36 h of sleep deprivation using ERP techniques and a stop-signal task. Sleep deprivation’s different effects on response inhibition in the two groups were explored through repeated-measures ANOVA. Behavioral data showed that in a baseline state, stop-signal response time was significantly faster in table tennis athletes than in non-athlete controls, and appeared significantly longer after sleep deprivation in both groups. ERP results showed that at baseline state, N2, ERN, and P3 amplitudes were lower in table tennis athletes than in non-athlete controls, and corresponding significant decreases were observed in non-athlete controls after 36 h of sleep deprivation. Table tennis athletes showed a decrease in P3 amplitude and no significant difference in N2 and ERN amplitudes, after 36 h of sleep deprivation compared to the baseline state. Compared to non-athlete controls, table tennis athletes had better response inhibition, and the adverse effects of sleep deprivation on response inhibition occurred mainly in the later top-down motor inhibition process rather than in earlier automated conflict detection and monitoring.

Understanding Sex-Based Kinematic and Kinetic Differences of Chasse-Step in Elite Table Tennis Athletes.

With the progress and innovation of table tennis technology, individualized training programs may deserve special attention. This study aimed to analyze elite table tennis athletes in chasse-step, with a particular focus on sex-based biomechanical differences. A total of 36 (18 males and 18 females) elite table tennis athletes performed topspin forehand of chasse-step. Angles and moments of hip, knee, and ankle joints were calculated using OpenSim (v4.2) with marker trajectories and ground reaction forces were measured via Vicon motion capture system and AMTI in-ground force platform. Males had greater hip and knee flexion angles during the entire motion phase and greater internal rotation angles of the hip during the forward swing phase. The joint stiffness of knee in males was greater than females in the frontal plane. Females in the forward swing phase showed greater hip flexion, adduction, and internal rotation moments than males. It was suggested that the difference may be due to the limitation of anatomical structures in sexes. Male table tennis athletes should strengthen lower extremity muscle groups to improve performance, while female table tennis athletes should focus on hip joint groups to avoid injury. The sex differences presented in this study could help coaches and athletes to develop individualized training programs for table tennis.

Upper Extremity Kinematics and Electromyographic Activity in Uninjured Tennis Players

There has been an increase in ulnar-sided wrist pain among tennis players. The purpose of this study was to establish a normative dataset of kinematic and electromyography (EMG) data during the forehand and two-handed backhand groundstrokes. In total, 20 adolescent United States Tennis Association (USTA) ranked tennis players (11/20 Male, Age = 15.0 ± 1.8 years, Height = 1.7 ± 1.1 m, BMI = 21.3 ± 3.4 kg/m2, 18/20 right-arm dominant) participated in this study. Kinematics (range of motion and angular velocity) and EMG data were simultaneously acquired during the forehand and two-handed backhand groundstrokes. Minimal differences were found between groupings of age, sex, and USTA ranking. The two-handed backhand groundstroke is characterized by bilaterally flexed elbows and ulnarly deviated wrists, with a flexed wrist and pronated forearm on the non-dominant side and an extended wrist and supinated forearm on the dominant side. EMG activation occurs bilaterally by peak backswing. The forehand groundstroke is characterized by a flexed elbow, pronated forearm, and ulnarly deviated and extended wrist. The wrist is at maximum ulnar deviation at ball impact. This study established an initial foundation for normative data for the forehand and two-handed backhand groundstrokes, which can be used for injury detection, rehabilitation, prevention, and ultimately performance improvement of tennis athletes.

Perceptual Judgments for Table Tennis Serve Recognition: An Event-Related Potentials Study

In the present study, visual attention processes in complex, sport-related decision-making tasks were examined. Psychophysiological and performance data recorded from 15 advanced table tennis athletes and 15 intermediate level undergraduates were compared. A total of 240 three-dimensional pictures of stimuli composed of a white ball and hitting location (black shade point) were presented via a screen, in which 25% represented side-backspin serves, and the other 75% represented non-side-topspin serves. Participants were instructed to report the types of serves. The results indicated that table tennis athletes responded more quickly and accurately. C1 and P1components were induced in the occipital region, N1 in the central region, and P3 in all regions. For table tennis athletes, in the phase of early sensory processing for stimuli features (such as hitting location), the cerebral cortex was activated at a higher level in comparison with undergraduates. This may be caused by the long-term exercise training. Athletes have to be very sensitive to the physical features of relevant movement stimuli. In the phase of recognizing stimuli structures or patterns, advanced athletes’ cerebral cortexes were activated higher and faster. This may help them more effectively match visual information about serves to patterns stored in long-term memory.

The Effect of Drill and Elementary Training to Forehand Ability of Tennis Athletes

Tennis athletes really need to master the forehand stroke well. A quality forehand technique will give athletes high confidence to be able to play tennis wellThis study aims to determine the effect of drill and elementary exercises in improving the forehand hitting ability of JPOK tennis athletes.

The results of this study that both drill and elementary training methods can improve the forehand hitting ability of JPOK tennis athletes. The results of data analysis, drill exercises obtained t-count is greater than t-table 17.60 > 2.365. Forehand only effect, t-count is greater than t-table 8.05 > 2.365. Drill and elementary training methods can be used as exercises to improve tennis athletes' forehand skills. Drill training is known to have more effect on tennis forehand ability

Planned Physical Workload in Young Tennis Players Induces Changes in Iron Indicator Levels but Does Not Cause Overreaching.

The current study aimed to examine the impact of the training load of two different training camps on the immunological response in tennis players, including their iron metabolism. Highly ranked Polish tennis players, between the ages of 12 and 14 years, participated in two training camps that were aimed at physical conditioning and at improving technical skills. At baseline and after each camp, blood samples were analyzed, and the fatigue was assessed. The levels of pro- and anti-inflammatory indicators, iron, and hepcidin were determined. The levels of the heat shock proteins, (Hsp) 27 and 70, were also measured. All the effects were evaluated using magnitude-based inference. Although the training camps had different objectives, the physiological responses of the participants were similar. The applied programs induced a significant drop in the iron and hepcidin levels (a small-to-very-large effect) and enhanced the anti-inflammatory response. The tumor necrosis factor α levels were elevated at the beginning of each camp but were decreased towards the end, despite the training intensity being medium/high. The changes were more pronounced in the female players compared to the male players. Altogether, the results suggest that low-grade inflammation in young tennis athletes may be attenuated in response to adequately designed training. To this end, the applied physical workload with a controlled diet and rest-controlled serum iron levels could be the marker of well-designed training.

Heeffectiveness of the personal approach to the technical readiness of table tennis athletes

Purpose-to establish the degree of effectiveness of the personal approach to the technical readiness of table tennis athletes. Material and methods. Students of a sports college took part in the study, namely eight players of different playing style, gender and sports category. The study was carried out for two years (2020-2021) and took place on the basis of the Kherson professional sports college. To assess the personality traits of tennis players, G. Eysenck's methodology for determining the type of temperament, T. Ehlers' method “Motivation for success” and Ch.D. Spielberger's "Personal Anxiety Self-Assessment Scale". The level of technical readiness of tennis players was determined by special control tests to assess the number of hits. Results: among tennis players, 62.5% of extroverts were found. One phlegmatic person was identified by the type of temperament, 25% -melancholic and 62.5% -choleric tennis players. The majority of tennis players (87.5%) showed an average level of motivation for success. 50% of tennis players had a high level of personal anxiety, 37.5% had an average level, and only one (12.5%) had a low level of this sign. In the mesocycle for extroverts, a special "Robot" simulator for table tennis was widely used. In the training mesocycle for introverts, the BCM exercise (work with a large number of balls) was applied. All table tennis athletes showed an improvement in the results of technicalreadiness for all tests in relation to the program norm. The organization and construction of training sessions taking into account the personal approach to the technical readiness of table tennis athletes led to the fact that the highest increase in results was shown by tennis players of different types of temperament. Conclusions: when organizing sports training, a coach should also take into account the personality traits of an athlete, since a tennis player can have effective technical readiness, but not always be able to realize it in training and competitive activities. This is evidenced by the statistically significant relationship between technical readiness and personal anxiety (0.920), as well as between the motivation for success and the temperament (0.752) of table tennis athletes.

Age and Gender Differences in Injuries and Risk Factors in Elite Junior and Professional Tennis Players.

Elite tennis athletes experience injuries throughout the entire body. Impairments in trunk stability, lower limb flexibility, and hip range of motion (ROM) are modifiable risk factors that can impact injuries and performance. Information on nonmodifiable risk factors such as age and gender is limited. The purpose of this investigation was to provide information on risk factors to direct clinical decision-making and injury prevention and rehab programming in this population. Prevalence and location of injuries will differ by age group and gender. Trunk stability, lower limb flexibility, and hip ROM will differ by age group and gender. Cross-sectional study. Level 3. A de-identified database (n = 237; females = 126) from the United States Tennis Association High Performance Profile (HPP) 2014-2015 was used for the analysis. Subjects were elite junior and professional tennis players (mean age 14.6 [range, 9-27] years). The HPP is a tennis-specific assessment and questionnaire that includes retrospective information on injury history. Subjects were categorized by injury, gender, and age. Injury locations were classified by region. Trunk stability measures included drop vertical jump (DVJ), single-leg squat, and prone and side planks. Lower limb measures included hamstring, quadriceps and hip flexor flexibility, and hip rotation ROM. A total of 46% of athletes reported an injury. Significant differences were found for injury prevalence and location by age group. Adolescent athletes (age 13-17 years) had more trunk injuries, while adult athletes (age ≥18 years) had more lower limb injuries. Adolescent athletes performed worse on DVJ, dominant side plank, and hamstring flexibility compared with young (age ≤12 years) and adult athletes. Significant gender differences in hip ROM included internal rotation on both the dominant and nondominant sides. Impairments in trunk stability, lower limb flexibility, and hip rotation ROM may affect both health and performance outcomes in this population. Elite tennis athletes may benefit from additional off court programming to address trunk and lower limb impairments. Adolescent elite tennis athletes may be at higher risk of trunk injuries. Age, gender, injury history, and impairments should be considered with all assessments and programming.

Youth participation in a wheelchair tennis program from a social relational perspective

ABSTRACT The purpose of this study was to explore the meaning of a wheelchair tennis program from the perspective of youth athletes, their caregivers and coaches through the lens of the social-relational model of disability. Data collection included field notes, focus group interviews and semi-structured individual interviews with six wheelchair tennis athletes (four males, two females) and eight adults (four mothers, one father and one grandmother, one program coordinator and one wheelchair tennis coach). A thematic analysis utilizing social relational model identified patterns within and across the data, allowing for description and interpretation of the meaning and importance of the themes. Two primary themes linked to both positive and negative experiences were identified: (1) disablism in everyday life, and (2) constructing ‘competent’ identities on the tennis court. The themes, taken together, describe the challenges faced, and the accomplishments achieved by the athletes and their families within a culture that marked them as different. Drawing on a social relational lens fosters an appreciation of anti-ableist aspects of sporting environments, simultaneously recognizing athletes’ experiences of surrounding structural and psychological barriers.

GROUNDSTROKE TRAINING MODEL BASED ON SITUATION GAME FOR FIELD TENNIS ATHLETES AGED 12-14 YEARS

This study aims to create a game situation-based groundstroke forehand and groundstroke backhand training model for tennis athletes aged 12-14 years and improve forehand and backhand skills using a game situation-based groundstroke training model for athletes aged 12-14 years. The research method used is the Research & Development Research & Development (R&D) Borg and Gall method. Subjects studied were 15 people and were athletes aged 12-14 years. The results of the pre-test test obtained an average of 31.73. Then, the post-test obtained an average of 40.00. The exercise correlation coefficient before and after the exercise model was given was 0.946 with a p-value of 0.00 < 0.05, so the conclusion was significant. In the mean difference test with SPSS, the mean = 8.26667 shows the difference between the pre-test and post-test, the result of t-count = 26,183, df = 19 and p-value = 0.00<0.05, which means there is a significant difference between before and after being given game situation based groundstroke training model treatment. Based on these results, it can be concluded that the game situation-based groundstroke training model for tennis athletes at the age of 12-14 years is effective and can improve the forehand groundstroke.

Flexibility, Position, and Strength of the Shoulder Complex in Pediatric and Adult Amateur Tennis Athletes.

Understanding the musculoskeletal adaptations in the shoulder complex of varying ages of tennis athletes may suggest preventive protocols and conditioning and rehabilitation programs to this population. This study aimed to generate a bilateral descriptive profile of shoulder flexibility, scapular and clavicular position, and muscle strength in pediatric and adult amateur tennis athletes. The outcome measures were compared between groups and sides. The number and percentage of athletes "at risk" according to cutoff values for shoulder range of motion (ROM) were also analyzed. Cross-sectional study. 36 pediatric and 28 adult amateur tennis athletes were tested. Outcome measures were ROM of shoulder flexion, abduction, internal and external rotation, posterior capsule tightness, pectoralis minor index (PMI), scapular upward rotation, clavicular elevation, and strength of the external rotators, serratus anterior, and lower trapezius of the dominant/nondominant sides. Pediatric athletes had greater dominant side external rotation (P = .01) and total ROM (P = .04), increased Low Flexion test (P = .01), and decreased PMI (P = .01) compared with the adults. Bilaterally, the pediatric athletes had greater dominant side external rotation ROM (P < .01) and decreased PMI (P = .002) as compared with their nondominant side, whereas the adults displayed lower values on posterior capsule tightness (P = .01) and decreased PMI (P = .02) on their dominant side compared with their nondominant side. For the remaining outcomes, no interaction effects were observed. The cutoff values for shoulder ROM showed that several athletes were "at risk" of shoulder problems. Upper extremity adaptations at the shoulder are present in both pediatric and adult tennis athletes. These data can assist clinicians in better understanding the biomechanical adaptations in the shoulder of amateur tennis athletes in different age groups.

Lower Limb Muscle Forces in Table Tennis Footwork during Topspin Forehand Stroke Based on the OpenSim Musculoskeletal Model: A Pilot Study

Introduction: Footwork is one of the training contents that table tennis players and coaches focus on. This study aimed to gain a thorough understanding of the muscle activity of the table tennis footwork and creating a musculoskeletal model to investigate the muscle forces, joint kinematic, and joint kinetic characteristics of the footwork during topspin forehand stroke. Methods: Six male table tennis athletes (height: 171.98 ± 4.97 cm; weight: 68.77 ± 7.86 kg; experience: 10.67 ± 1.86 years; age: 22.50 ± 1.64 years) performed chasse step and one-step footwork to return the ball from the coach by topspin forehand stroke. The kinematics, kinetics, and muscle activity of the lower limb were recorded by the motion capture, force platform, and Electromyography (EMG) system. Statistical parametric mapping (SPM) analysis was used to investigate any difference between the chasse step and one-step footwork during the stroke. Results and Conclusion: The muscle force of the biceps femoris long head (p < 0.001), lateral gastrocnemius (p < 0.001), vastus lateralis (p < 0.001), vastus medial (p < 0.001), rectus femoris (p < 0.001), and tibia anterior (p < 0.001) of the chasse step were significantly greater than the one-step footwork during the early stroke phase (stance). At the end of the stroke phase (push-off), the muscle force of the biceps femoris long head (p < 0.001), medial gastrocnemius (p < 0.001), lateral gastrocnemius (p < 0.001), rectus femoris (p < 0.001), and tibias anterior (p < 0.001) in the chasse step footwork was significantly greater than the one-step footwork. The muscle force of the ankle plantar flexor and valgus muscle groups in the one-step was significantly greater than in the chasse step. Besides, the moment and angle of hip flexion (p = 0.001) and axial rotation (p = 0.009) were significantly greater for the chasse step than the one-step footwork, as well as the ankle plantarflexion angle (p < 0.001) and moment (p < 0.001) of the one-step footwork were significantly higher than the chasse step footwork. The results of this study can be applied to movement control and injury prevention in table tennis footwork.

In order to explore the effect of convolutional neural network (CNN) on the detection of athletes and balls in table tennis, and to solve the problems of low accuracy and weak generalization ability of table tennis athletes training data, this paper analyzed videos of table tennis athletes. For the detection of multiple targets in the videos, including athletes and balls, we used Yolov3 as a deep learning framework, and CNN as an automatic detection method when processing images. We trained and test the video data to improve the stability and accuracy of target detection, through modifying its model on the basis of the Yolov3 model. Finally, we detect the movement trajectories of athletes and balls in table tennis videos stably, and the accuracy is above 0.8.

장기간 시합 미참가로 인한 여자탁구 학생선수와 실업선수의 선수 정체성 변화

Purpose: Purpose: This study examined the chages in athletic identity of Korean female student and professional athletes due to long-term non-participation in competitions. The wide spread of COVID-19 made the table tennis athletes impossible to participate in scheduled competitions more than 11 months. This type of forced non-participation in games for a long period of time was very rare case in recent years. Methods: A total of 65 female high school table tennis student athletes and 35 female professional athletes responded to the athletic identity questionnaire. The were requested to recall the time when they were normally train and participate before the COVID-19. The participants responded to each of the athletic identity item twice: 1) normal participation period before COVID-19 and 2) more than 11 months of non-participation due to the pandemic. Paired t-test and repeated two-way ANOVA were performed. Results: The analyses of the data revealed that although the two groups showed lowered levels of athletic identity, long-term non-participation in competitions lowered athletic identity of the professional players more drastically compared to the student counterparts. The interaction effects were found for all of the subscales of athletic identity (self identity, social identity, exclusivity, positive emotion, and negative emotion). Overall, the student athletes who palyed for the national team showed moderate decreases in athletic identity. For the professinal athletes, the patterns of decreases in athletic idnetity before and after the long non-participation were similar across different status in terms of national team nomination. In conclusion, unintended non-participation in competitions for more than 11 months lowered athltetic identity of the professional table tennis players more deeply compared to the student athletes. Conclusion: In order to prevent negative impact on athletic identity, opportunities for participation in various competitions, even in the form of matches without spectators, are necessary for the high performance athletes.
