Purpose:To test the hypotheses that the metabolic profile of table tennis is dominantly aerobic, anaerobic energy is related to the accumulated duration and intensity of rallies, and activity and metabolic profile are interrelated with the individual fitness profile determined via table tennis–specific tests. Methods:Eleven male experienced table tennis players (22 ± 3 y, 77.6 ± 18.9 kg, 177.1 ± 8.1 cm) underwent 2 simulated table tennis matches to analyze aerobic (WOXID) energy, anaerobic glycolytic (WBLC) energy, and phosphocreatine breakdown (WPCr); a table tennis–specific graded exercise test to measure ventilatory threshold and peak oxygen uptake; and an exhaustive supramaximal table tennis effort to determine maximal accumulated deficit of oxygen. Results:WOXID, WBLC, and WPCr corresponded to 96.5% ± 1.7%, 1.0% ± 0.7%, and 2.5% ± 1.4%, respectively. WOXID was interrelated with rally duration (r = .81) and number of shots per rally (r = .77), whereas match intensity was correlated with WPCr (r = .62) and maximal accumulated oxygen deficit (r = .58). Conclusions:The metabolic profile of table tennis is predominantly aerobic and interrelated with the individual fitness profile determined via table tennis–specific tests. Table tennis–specific ventilatory threshold determines the average oxygen uptake and overall WOXID, whereas table tennis–specific maximal accumulated oxygen deficit indicates the ability to use and sustain slightly higher blood lactate concentration and WBLC during the match.

In general, sporting triumphs are likely to be direct reflections of a society’s socioeconomic development. Chinese table tennis achievements have had a huge impact on Chinese society since 1950. The Chinese table tennis team has won every title in a row, which not only humiliates the World Table Tennis Federation (ITBF) but also additionally prompts the present situation of “flourishing Chinese table tennis and debauched global table tennis.” Furthermore, the impacts of achievement on Chinese society are not restricted to sports. It essentially affects society. Regardless of the way that table tennis has a long history, there is little critical familiarity with the physiological necessities of players, particularly during challenge. In this layout, a gander was taken at exploring the ongoing comprehension of the body’s capabilities during table tennis planning and competition, as well as what kind of readiness is involved. The anaerobic alactic system is fundamentally called into play during hard practice and challenge, while the tirelessness structure is depended upon to recover the anaerobic stores depleted during such effort, according to match and practice examination of table tennis coordination. While the anaerobic alactic system is the most overwhelming structure involved during seasons of effort in table tennis, a solid breaking point in steadiness permits a player to recover more quickly for the accompanying match and day of competition. This study surveys explicit examinations connected with cutthroat table tennis and accentuates the requirement for table tennis-explicit preparation and exploration drives. The contribution of the study was to see how sports vision training affected certain visual abilities and table tennis players’ ability to play. The experimental group that followed a 12-week sports vision training regimen demonstrated a significant improvement in selected visual abilities and table tennis playing ability, according to the study’s findings. On all of the examined variables, the control group showed no significant improvement.

Table tennis is important and challenging project for robotics research, and table tennis robotics receives a lot of attention from academics. Trajectory tracking and prediction of table tennis is an important technology for table tennis robots, and its estimation accuracy is also disturbed by non-Gaussian noise. In this paper, a novel Kalman filter, called minimum error entropy unscented Kalman filter (MEEUKF), is employed to estimate the motion trajectory of physical model of a table tennis. The simulation results show that the MEEUKF algorithm shows outstanding performance in tracking and predicting the trajectory of table tennis compared to some existing algorithms.

Lightweight sandwich panels (LWSP) have been used in various sectors of construction and transportation industries. However, due to the cost and complexity of the manufacturing process, their usage in high level sport equipment has been somewhat neglected. This study investigates the feasibility of using a wood veneer sandwich panel to construct the playing surface of a table tennis table. The effects of material parameters, such as the face sheet thickness, core configuration, core thickness and surface coating, on the dynamic friction coefficient and coefficient of restitution, which ultimately dictate the speed, bounce and spin of the ball, will be examined. All results from characterisation of the LWSP table using the International Table Tennis Federation (ITTF) standards will be compared with those from commercially available tables. The material parameters identified to yield the most consistent and favourable characteristics for a table tennis game will be applied for construction of a full size demonstration table.

The identification, positioning and grabbing path planning of table tennis balls are the preconditions for the robot to pick up table tennis balls autonomously. A method of table tennis identification, positioning and grabbing path planning based on monocular vision image processing is proposed. By analyzing the characteristics of table tennis images, a table tennis image segmentation method based on color and contour features is designed. The color and contour features of table tennis images are extracted, and HSV is used for image preprocessing. Image segmentation is processed by binarization, and Hough circle is used to detect contour recognition, and the segmentation image of table tennis balls is obtained by color combination. Convert the camera imaging coordinates to obtain the pixel position of the table tennis ball in the image. A ball picking path planning based on ant colony algorithm is designed. This paper provides a theoretical reference for the identification, positioning and path planning of autonomous ball picking.

This article takes table tennis as the research object, mainly extracts a large number of table tennis video trajectories, and combines the kinematic analysis method to reduce the noise of the extracted target to improve the accuracy of the table tennis trajectory and obtain the table tennis trajectory. The parameter group is used to simulate the trajectory of table tennis; based on the MATLAB environment to realize the table tennis trajectory simulation that provides the initial velocity and coordinates, complete the capture of the table tennis drop point. This article uses the two-dimensional information in the image to estimate the parameter values that form the three-dimensional information and then calculates the three-dimensional information based on the estimated parameter values. The unscented Kalman filter is used to estimate the trajectory parameters and rotation parameters of table tennis, and the algorithm for calculating and updating markers in real time is proposed, which reduces the influence of calculation errors on the estimation process and improves the accuracy of parameter estimation. First, establish a table tennis movement model and choose a suitable model to describe the translation and rotation movement of the table tennis. Then, based on the extended Kalman filter algorithm and the unscented Kalman filter algorithm, the ball flight trajectory estimation algorithm is established. Finally, an actual image acquisition system is built to collect trajectory information and surface information images from the actual table tennis movement. Processing is performed to obtain the positions of the center of the ping pong ball and the marked points on the corresponding sensors. Simulation and experimental results show that the proposed algorithm can effectively estimate the trajectory, linear velocity, and angular velocity parameters of a table tennis ball, and the selection of the initial value has little effect on the algorithm.

Texto completo da fonteResumo:
Spatial cognition facilitates the successful completion of specific cognitive tasks through lateral processing and neuroplasticity. Long-term training in table tennis induces neural processing efficiency in the visuospatial cognitive processing cortex of athletes. However, the lateralization characteristics and neural mechanisms of visual–spatial cognitive processing in table tennis players in non-sport domains are unclear. This study utilized event-related potentials to investigate differences in the spatial cognition abilities of regular college students (controls) and table tennis players. A total of 48 participants (28 controls; 20 s-level national table tennis players) completed spatial cognitive tasks while electroencephalography data were recorded. Task performance was better in the table tennis group than in the control group (reaction time: P < 0.001; correct number/sec: P = 0.043), P3 amplitude was greater in the table tennis group (P = 0.040), spatial cognition showed obvious lateralization characteristics (P < 0.001), table tennis players showed a more obvious right-hemisphere advantage, and the P3 amplitude in the right hemisphere was significantly greater in table tennis athletes than in the control group. (P = 0.044). Our findings demonstrate a right-hemisphere advantage in spatial cognition. Long-term training strengthened the visual–spatial processing ability of table tennis players, and this advantage effect was reflected in the neuroplasticity of the right hemisphere (the dominant hemisphere for spatial processing).

Purpose The purpose of this paper is to examine the 2004-2015 financial performance (FP) of the national non-profit US Table Tennis Association using financial effectiveness (FE) indicators and financial efficiency (FY) ratios. Design/methodology/approach Archival data were used together with a case study method. FP was evaluated by net income; FE was indicated by total assets and total revenues while FY was examined by program services ratios and support services ratios. Findings On an average, the FP of the organization was poor ($6,475.00 net loss per year), FE was moderate (50 percent increases in assets and revenues), and the FY was poor (80 percent revenues spent on program services with a return on asset of 201.5 percent). Research limitations/implications By using case study method, the results may not be generalizable to other national non-profit sports organizations with non-financial goals. Practical implications The paper suggests that national non-profit organizations can enhance their FP by focusing on both FE and FY. Originality/value The study utilized both FE and FY measures to evaluate the FPs – a major shortfall in similar studies.

Texto completo da fonteResumo:
In the system design of table tennis robot, the important influencing factors of automatic detection of technical and tactical indicators for table tennis are table tennis rotation state, trajectory, and rebound force. But the general prediction algorithm cannot process the time series data and give the corresponding rotation state. Therefore, this paper studies the automatic detection method of technical and tactical indicators for table tennis based on the trajectory prediction using the compensation fuzzy neural network. In this paper, the compensation fuzzy neural network algorithm which combines the compensation fuzzy algorithm and recurrent neural network is selected to construct the automatic detection of technical and tactical indicators for table tennis. The experimental results show that the convergence time of the compensation fuzzy neural network is shorter, the training time is shortened, and the prediction accuracy is improved. At the same time, in terms of performance testing, the model can accurately distinguish the influence of table tennis rotation state and rebound on table tennis motion estimation, so as to improve the accuracy of motion trajectory prediction. In addition, the accuracy of trajectory prediction will be improved with the increase of input data. When the number of data reaches 30, the trajectory prediction error is within the actual acceptable error range.

Total daily energy expenditure (TEE) and physical activity level (PAL) are important for adequate nutritional management in athletes. The PAL of table tennis has been estimated to about 2.0: it is categorized as a moderateactivity sport (4.0 metabolic equivalents [METs]) in the Compendium of Physical Activities. However, modern table tennis makes high physiological demands. The aims of the current study were to examine (1) TEE and PAL of competitive table tennis players and (2) the physiological demands of various types of table tennis practice. In Experiment 1, we measured TEE and PAL in 10 Japanese college competitive table tennis players (aged 19.9 ± 1.1 years) using the doubly labeled water (DLW) method during training and with an exercise training log and self-reported energy intake. TEE was 15.5 ± 1.9 MJ·day-1 (3695 ± 449 kcal·day-1); PAL was 2.53 ± 0.25; and the average training duration was 181 ± 38 min·day-1. In Experiment 2, we measured METs of five different practices in seven college competition players (20.6 ± 1.2 years). Three practices without footwork were 4.5–5.2 METs, and two practices with footwork were 9.5–11.5 METs. Table tennis practices averaged 7.1 ± 3.2 METS demonstrating similarities with other vigorous racket sports. In conclusion the current Compendium of Physical Activities underestimates the physiological demands of table tennis practice for competition; the estimated energy requirement should be based on DLW method data.

AbstractThis study investigates the relationship of trunk rotational velocity with mobility and curvature of the spine in wheelchair table tennis players. Eleven para table tennis players and 13 able-bodied athletes performed 5 seated trunk rotations to each side with 1 kg barbell placed on the shoulders. Trunk rotational velocity and respective angular displacement were significantly lower in para table tennis players compared to able-bodied athletes. Both groups showed similar values of thoracic kyphosis. However, para table tennis players exhibited lower lumbar inversion and pelvic retroversion compared to able-bodied athletes. Peak and mean velocity in the acceleration phase of trunk rotation correlated with angular displacement in both para table tennis players (r=0.912, p=0.001; r=0.819, p=0.013) and able-bodied athletes (r=0.790, p=0.026; r=0.673, p=0.032). These velocity values were also associated with lumbar curvature (r=-0.787, p=0.003; r=− 0.713, p=0.009) and pelvic tilt angle (r=0.694, p=0.014; r=0.746, p=0.007) in para table tennis players. Findings indicate that slower velocity of trunk rotations in para table tennis players might be due to their limited range of trunk rotational motion. Decreased posterior concavity could also contribute to these lower values. However, other biomechanical factors may have an impact on the association between these variables and have yet to be documented.

Forty-eight elite table tennis players participated in this study: 24 men (25.3 ± 4.07 years) and 24 women (22.3 ± 3.8 years). During simulated competition, temporal structure, heart rate (HR), and lactate (LA) were evaluated. The maximum ergospirometric evaluations were performed in a laboratory. The total table tennis (TT) time and the total resting time (TRT) were longer for men (p < 0.05), but game density was higher for women (p < 0.05). During rallies, the real playing time (RPT) was longer for women, while the TRT was longer for men (p < 0.05). The maximum HR, minimum HR, and maximum LA concentrations were higher for men (p < 0.05). The obtained data reveal gender differences in the physiological, metabolic, structural, and temporal variables in table tennis players. The analysis of the studied variables could allow training sessions to be planned and organized according to table tennis players’ gender.

Sensor technology has been deeply into the sports industry, with the help of sensors to monitoring and collection data for the physical training in real-time. In table tennis, wearable sensors can record the amount of training, movement essentials, and the number of strokes of both hands and assist in the testing and evaluation of table tennis. This paper analyzes the application of wearable sensors in table tennis training activities and the details of signal collection and feature extraction. At the same time, machine learning technology often used to recognize and test table tennis training data, and a support vector machine (SVM) is one of the representative classifiers. Applying the processed signal data to the classification and testing of SVM can effectively identify the movement and evaluate the training effect and athletes’ physical fitness. The integration of intelligent sensors and table tennis can effectively improve the evaluation efficiency and quality in the process of teaching and training.

Texto completo da fonteResumo:
Table tennis is an extremely popular sport throughout the world as it requires no expensive equipment, specialized amenities, or physical contact among players, and the pace of play can be adapted to allow participation by players of all skill levels, ages, and abilities. It is an aerobic-dominant sport driven primarily by the phosphagen system because rallies are relatively brief (several seconds) and separated by longer rest periods. Several studies have shown that physical interventions including table tennis can help prevent cognitive decline and dementia. Accordingly, the present paper provides an overview of the basic physical and cognitive demands of table tennis, reviews previous studies reporting improvements in physical and brain health across different non-clinical and clinical populations, and critically evaluates the usefulness of table tennis intervention for the prevention of cognitive decline and dementia. This review suggests that table tennis intervention could be a powerful strategy to prevent cognitive decline and dementia in the elderly.

This study aims to investigate table tennis players’ personality traits and motives in the frame of the Big Five personality model and the self-determination theory (SDT) of motivation. A total of 447 Italian table tennis players ranging in level of play between the regional and international levels participated in the study. They completed a self-report questionnaire measuring their personality traits and motives to play table tennis. Findings showed conscientiousness as the most distinctive trait of table tennis players. No differences were detected between elite and non-elite players. Table tennis players are mainly motivated by factors belonging to the intrinsic pole of the self-determination motivational continuum. External reinforcements represent a minimal incentive to play this sport both for elite and non-elite athletes. The current findings help clarify the relationships between personality traits, playing certain types of sports, and achieving different performance levels. We conclude by outlining implications for applied sport psychology.
