AbstractDisplays of anxiety in table tennis were assessed through subjective (a self-report questionnaire), physiological (heart-rate variability) and kinematic variables. Using a within-group crossover design, 9 university-level table tennis players completed a series of serves under low- and high-anxiety conditions. Anxiety manipulation was achieved through the introduction of a national standard table tennis player, known to the participants, to receive serves in the high-anxiety condition, whilst serves were received by no opponent in the low-anxiety condition. Automated motion capture systems consisting of high-speed 3D motion cameras and analytical software (QUALISYS) determined the subject’s movement kinematics: bat face angle (degrees) and serve routine duration (s). Self-reported state anxiety (MRF-Likert) and heart rate measurements were collected to examine changes between conditions. Contrary to the hypothesis, bat face angles did not change significantly between anxiety conditions (F (1.8) = 2.791, p = 0.133) and movement times were faster in the high-anxiety condition. In light of these findings, research into other facets of movement behaviour must be analysed to gain further understanding of the effects of anxiety on performance, which remain unclear.

The Cost

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 COVID-2019 pandemic forced many people to take a different look at the world around them, to reconsider their attitude to their social circle, to optimize costs, to make adjustments to the foundations of life, to discover new activities. All areas of activity suffered losses both in the field of economy and in the field of resources. While the business was looking for new solutions to survive, the sport survived clinical death. The losses of athletes and organizations were estimated in the hundreds of millions of dollars. The number of children in sports sections has decreased. Table tennis is one of the most popular sports around the world, both in terms of the number of people involved and the number of countries where it develops. The International Table Tennis Federation (ITTF) has more than 200 countries and is one of the three leading world federations in this indicator. This article will describe the problems and solutions that have arisen in table tennis as a result of the emergence of a new virus.

The Impact

This study aimed at exploring the impact of using a training program which employs simulation of virtual reality on competitive state anxiety; and the level of performance of the table tennis players in Jordan and Saudi Arabia. The sample consisted of 10 players (age 13–15 years); with five players purposefully selected from each country. The researchers administered the training program, using the immersive and nonimmersive virtual reality for 6 weeks 5 times a week. Competitive state anxiety inventory "CSAI-2" and a questionnaire for evaluating the performance in the "fore-hand drive" were used. The data were analyzed, using Mann–Whitney U test, Wilcoxon signed ranks test; and Chi square test. The results indicated that the program with simulation of virtual reality had a positive impact on the study parameters as the post measurement was significantly greater than the pre training measurement. In light of the results, the researchers recommended modern technological devices be used in sports psychology. Also, immersive simulation of virtual reality is recommended.

Kinematic Measures

Although many studies on choking under pressure used closed skills, such as golf putting, we examined the influence of pressure on movement during a dynamic skill by studying participants’ kinematic and kinetic changes during a table tennis forehand task under pressure. Thirty novice table tennis players hit forehand shots toward a target for 135 practice trials and then performed 10 no-pressure and 10 pressure trials. We added psychological pressure by instructing participants they could earn monetary rewards for successful performance and by cancelling accumulated scores for a poor performance. We measured racket head and ball movements as kinematic variables and grip force as a kinetic variable. We also measured state anxiety and heart rate as checks on our manipulation of psychological pressure. In the pressure condition, both state anxiety and heart rate increased significantly ( p < .025), though the pressure level was relatively small. Analysis of kinematic measures revealed that back swing and forward swing were reduced in length; speed of forward swing and ball speed decreased significantly ( p < .008) under pressure. Also, under pressure, ball and racket contact point shifted forward significantly ( p < .008) to reduce the distance between impact and target locations, and performance declined as the ball-landing locations shifted leftward ( p < .007). Grip force showed no significant change. We conclude that, under pressure, movement was modified toward reduced displacement and lower speed in an apparent risk-aversive hitting strategy; these modifications resulted in a performance decrement.

Abstract The present study investigated the influence of contextual fear in comparison to relaxation on heart period variability (HPV), and analyzed differences in HPV between low and high anxious, nonclinical subjects. Fifty-three women participated in the study. Each subject underwent four experimental conditions (control, fear, relaxation, and a combined fear-relaxation condition), lasting 10 min each. Fear was provoked by an unpredictable aversive human scream. Relaxation should be induced with the aid of verbal instructions. To control for respiratory effects on HPV, breathing was paced at 0.2 Hz using an indirect light source. Besides physiological measures (HPV measures, ECG, respiration, forearm EMG, blood pressure), emotional states (pleasure, arousal, dominance, state anxiety) were assessed by subjects' self-reports. Since relaxation instructions did not have any effect neither on the subjective nor on the physiological variables, the present paper focuses on the comparison of the control and the fear condition. The scream reliably induced changes in both physiological and self-report measures. During the fear condition, subjects reported more arousal and state anxiety as well as less pleasure and dominance. Heart period decreased, while EMG and diastolic blood pressure showed a tendency to increase. HPV remained largely unaltered with the exception of the LF component, which slightly decreased under fear induction. Replicating previous findings, trait anxiety was negatively associated with HPV, but there were no treatment-specific differences between subjects with low and high trait anxiety.
