AbstractPurpose. The aim of the study was to compare the spatial component of proprioceptive ability by reproducing a upper limb movement typical in table tennis and fencing. Methods. The research comprised 41 young males of which 12 were table tennis players, 14 fencers, and 15 not involved in any competitive sports as a control. The experiment was based on assessing the precision of pronation and supination of the forearm at the elbow joint in recreating a set movement range by use of a goniometer. Results and conclusions. The results point to a higher level of proprioceptive ability in fencers and table tennis players than the control group but only in respect to the tasks executed with the dominant limb. This is inferred to be the result from the specific character of both sports (i.e. the intensive use of one limb and the consequent laterality of that limb) causing higher sensitivity and proprioception. This may provide a link between swordplay, table tennis, and the level of proprioception. The research methodology used herein may be useful in monitoring fencing training. Although not unequivocally statistically significant, the results indicate the potential for further research in this area.

Pressure Sense

Joint position sense and force reproduction are the most commonly used measures of proprioception. It is interesting to measure proprioception in integration of the factors most commonly viewed as the most important in table tennis—speed, in particular quick reaction. The aim of this study was to evaluate the accuracy of replication of a specific range of motion and force of hand pressing under conditions of limited time. Forty table tennis players and 30 non-athletes participated in the study. Electrogoniometric and dynamometric methods were used in the investigation. The accuracy of replication of pronation and supination movements of the forearm at the elbow joint and force of hand pressing under conditions of limited time (performing the activity as fast as possible in response to visual signals) were measured. The tests performed in the study revealed that both female and male table tennis players were characterized by a higher level of forearm position sense during performing the fastest possible pronation and supination movements in most of the tasks. Better results of table tennis players than of the control group suggest that joint position and hand pressure sense integrated with quick reaction are important performance factors in table tennis. The results also indicate opportunities for using this methodology to monitor training.

Limb Kinematics

To better understand the biomechanics of para-table tennis players, this study compared the shoulder, elbow, and wrist joint kinematics among able-bodied (AB) and wheelchair players in different classifications. Nineteen participants (AB, n = 9; classification 1 (C1), n = 3; C2, n = 3; C3, n = 4) executed 10 forehand and backhand topspin drives. Shoulder abduction/adduction, elbow flexion/extension, wrist extension/flexion, respective range of motion (ROM), and joint patterns were obtained using inertial measurement unit (IMU) sensors. The results showed clear differences in upper limb kinematics between the able-bodied and wheelchair players, especially in the elbow and wrist. For the para-players, noticeable variations in techniques were also observed among the different disability classes. In conclusion, wheelchair players likely adopted distinct movement strategies compared to AB to compensate for their physical impairments and functional limitations. Hence, traditional table tennis programs targeting skills and techniques for able-bodied players are unsuitable for para-players. Future work can investigate how best to customize training programs and to optimize movement strategies for para-players with varied types and degrees of impairment.

Table tennis has a broad mass base in our country and is a sport suitable for all ages. It has achieved outstanding results in the international arena and has become our country’s traditional advantage. To engage in professional table tennis, table tennis players are required to have good physical quality. However, table tennis is actually a high-intensity, high-skills sport. It has a very large impact on the main power-generating parts and joints of the athlete’s body. Soldiers and ball players often suffer from sports injuries. Therefore, it is necessary to carry out the nutrition corresponding supplements and targeted training. Therefore, the experimental group members were supplemented with nutritious food to distinguish the control group. The operation steps and experimental principle of this method are provided in detail in this article. Based on the above test scheme, a comparative experiment has been done and a number of physiological tests on the two groups of sports have been carried out. It includes the statistical analysis of athletes’ body composition changes after the experiment and the comparative analysis of body composition before and after nutrition intervention in the experimental group. Analysis of experimental data shows that nutritional food can improve the physical indicators of table tennis players and enhance the overall health evaluation coefficient.

Branched Chain

The purpose of this article is to in-depth explore the specific effects of supplementation of branched-chain amino acids on table tennis performance and its mechanism. Athletic ability refers to the ability of a person to participate in sports and training. It is a comprehensive manifestation of a person’s physical form, quality, function, skills, and psychological abilities. From a biochemical point of view, the level of exercise capacity mainly depends on the energy supply, transfer, and utilization of energy during exercise. The metabolic basis of exercise capacity and its influencing factors, the central and peripheral causes of sports fatigue, and the general law of the recovery of consumed substances after exercise provide a theoretical basis for athletes’ selection of talents, evaluation of training effects, and formulation of training plans. The main function of the vision sensor is to obtain enough of the most primitive images to be processed by the machine vision system. Use the latest vision sensor technology for in-depth research. This article takes 20 professional table tennis players with the same sports score as the research object and divides the athletes into the control group and observation group supplemented with branch chain amino acids. For the observation group, the exercise plan is to design two one-hour table tennis games, divided into two days, with a 10-minute break after half an hour of the game, and the athletes in the observation group to have a weight of 0.3 g/kg before and during the rest of the game. Weight measurement supplemented with branched-chain amino acids, the control group, athletes supplemented with the same amount of ordinary mineral water, the athletes’ fatigue index, endurance index, and reaction ability index were scored, and the athlete’s blood was drawn to test the sports-related biochemical indicators after the end of table tennis. The results of the study showed that after supplementation with branched-chain amino acids, the fatigue index of the athletes in the observation group was ( 7.5 ± 1.2 ), the fatigue index of the control group was ( 11.2 ± 1.5 ), the endurance index of the observation group was ( 28.4 ± 4.8 ), that of the control group was ( 19.6 ± 3.7 ), the reaction ability index of the observation group was ( 18.4 ± 4.2 ), and the control group was ( 12.3 ± 2.8 ). At the same time, the athletes’ plasma antioxidant capacity and metabolism level of the observation group were significantly higher than those of the control group. Therefore, it can be seen that supplementing branched-chain amino acids can effectively improve the athletic ability of table tennis players.

The aim of the present study was to analyze the effects of ballistic and power training on table tennis players’ electromyography (EMG) changes. Thirty male table tennis players, who were able to perform top spin strikes properly, were randomly assigned to three groups: power training (PT; n = 10); ballistic training (BT; n = 10); and no training (CON = control group; n = 10). PT and BT were performed 3 times weekly for 8 weeks. Before and after training programs, a one-repetition maximum test (1RM) and the EMG activity of all the subjects’ upper/lower body muscles while performing top spin strokes were analyzed. After training, significant interactions (group × time) were observed in increasing 1RM strength in upper/lower muscles (p < 0.05). However, neither training type had any significant effect on muscle EMG activity. These findings suggest that there should not necessarily be any significant change in the EMG signal after BT and PT despite the increase in muscle strength.

Abstract Based on a systematic review of the literature on anger and anger management in sport, there is evidence that anger might be dysfunctional, especially in sports requiring selective attention and fine-tuned motor skills. The research literature suggests that cognitive-behavioral intervention programs can be fruitful in helping athletes to understand and control dysfunctional anger. Therefore, the main goal of the present study was to evaluate the effectiveness of a brief training program for table tennis players in cognitive-behavioral anger management that aimed at changing their noneffective anger reactions. The sample comprised 18 young competitive table tennis players (age range from 16 to 22 years) divided randomly into a treatment (n = 10) and a control group (n = 8). A trained group leader instructed the treatment group. Six sessions were held over a period of two months. Cognitive-relaxation coping skills associated with social skills of subjects from the treatment group were compared to no-treatment controls. Psychological measurements (i.e., self-reports on anger) were applied before, during and after treatment as well as in a follow-up session. The one-year follow-up session revealed that, in contrast to the control group, the treatment group showed a significant reduction in outwardly negative anger expression as well as anger reactions specific to table tennis. Despite limitations inherent in the research design, the training program was deemed effective.

Measuring Reaction Time

In this study the ability of elite table tennis players with intellectual disability (ID) to adapt their service/return to specific ball spin characteristics was investigated. This was done by examining the performance of 39 players with ID and a reference group of 8 players without ID on a standardized table tennis specific test battery. The battery included 16 sets of 15 identical serves that had to be returned to a fixed target, and two additional tests measuring reaction time and upper limb speed. A 2 × 4 ANOVA (with group and type of spin as independent variables) with repeated measurements (15 consecutive returns) supported the hypothesis that elite table tennis players with ID were significantly less proficient than their counterparts without ID, but both groups demonstrated a comparable progression in learning. Spearman correlation coefficients indicated a positive relationship between accuracy of return and upper limb speed (rho = 0.42: p < .05) and reaction time (rho = 0.41: p < .05), showing that these generic factors are useful in partially explaining skill variations in specific sports.

SummaryPatients undergoing surgery for coronary artery bypass graft or heart valve replacement had their platelet count and mean volume measured pre-operatively, immediately post-operatively and serially for up to 48 days after the surgical procedure. The mean pre-operative platelet count of 1.95 ± 0.11 × 1011/1 (n = 26) fell significantly to 1.35 ± 0.09 × 1011/1 immediately post-operatively (p <0.001) (n = 22), without a significant alteration in the mean platelet volume. The average platelet count rose to a maximum of 5.07 ± 0.66 × 1011/1 between days 14 and 17 after surgery while the average mean platelet volume fell from preparative and post-operative values of 7.25 ± 0.14 and 7.20 ± 0.14 fl respectively to a minimum of 6.16 ± 0.16 fl by day 20. Seven patients were followed for 32 days or longer after the operation. By this time they had achieved steady state thrombopoiesis and their average platelet count was 2.44 ± 0.33 × 1011/1, significantly higher than the pre-operative value (p <0.05), while their average mean platelet volume was 6.63 ± 0.21 fl, significantly lower than before surgery (p <0.001). The pre-operative values for the platelet volume and counts of these patients were significantly different from a control group of 32 young males, while the chronic post-operative values were not. These long term changes in platelet volume and count may reflect changes in the thrombopoietic control system secondary to the corrective surgery.
