Objective: This study aimed to investigate the impact of strength training on the quality of the forehand pull technique in table tennis players.Methods: Two Chinese national second-class table tennis players, both aged 32, were selected as the experimental subjects and underwent a 4-week strength training program. The training program consisted of two sessions per week, including full-body strength training and special strength training.Results: Using the Eagle Eye System, the forehand topspin and backspin processes of the two athletes were recorded and analyzed. The results indicated that the athletes made some progress in their forehand pull technique, although the improvement was not statistically significant. Notably, the stability and speed of their return shots showed improvement.Conclusion: Continuous full-body and special strength training did not yield significant improvements in the quality of the forehand pull technique in table tennis players. The enhancement of a specific technique in table tennis relies more on skill utilization than solely on strength training. These findings provide valuable insights for coaches and players, highlighting the need to emphasize personalized training plans that consider the importance of strength training. Moreover, the Eagle Eye System proved to be an effective measurement tool for evaluating technical improvements and monitoring athlete progress.

Objective: To study the relationship between the training frequency and technical level of 7-year-old beginners in table tennis, and provide parents with a reference for arranging their children's training frequency.Method: Five 7-year-old children who started training at the same time were selected as the experimental subjects. The weekly training frequency of the five children varied, but the training plan and coach were the same.The technical level of the five children was analyzed through the Eagle Eye system.The results showed that the technical level of children who trained seven times a week was significantly better than that of children who trained four times a week.Therefore, parents should pay attention to and reasonably arrange their children's table tennis training plan to promote their skill development, and it is recommended to insist on training every day of the week.

Study jects: 30 ordinary female college students who had no professional sports training; Study method: subjects had a ketogenic diet for 30 days and completed a daily exercise program as required. Measurement indicators: measured before and after the experiment 1. Body weight, 2. subcutaneous fat and muscle thickness in the anterior and posterior segments of the upper arm, 3. muscle condition in the anterior and posterior femoral region, 4. Maximum oxygen intake, 5. maximum heart rate, 6. blood glucose and blood β ketone. The results showed that: 1. The aerobic training in the experimental and control groups decreased in the mean sebum thickness in each group. 2 The mean maximum oxygen intake improved in both groups and one-sided T test showed significant differences in the experimental groups. 3 Mean heart rate and weight decreased in the control group, while the mean heart rate increased more weight, with the one-sided T test for maximal heart rate significantly significantly in the experimental group significantly significantly. 4. Through the design of aerobic training, the maximum oxygen content in the experimental group increased significantly.we can draw the following conclusions: 1. Certain intensity, time and regular aerobic training have certain effect on weight loss in non-experimental state and experimental state, which can effectively reduce the fat content of all parts of female college students and improve the quality of lean body; 2. certain intensity aerobic exercise based on ketogenic diet will make female college students have better slimming effect, and this mode will not cause adverse effects on the body within a certain range.

Introduction: Digital platforms are increasingly used in university physical education (PE), but the psychological pathways associated with platform-supported PE remain insufficiently understood. Because individual random assignment was not feasible in the authentic educational setting, this study examined post-intervention group differences and self-determination theory (SDT)-consistent associations, distinguishing need satisfaction from need frustration. Methods: An 8-week post-intervention intact-class quasi-experimental study was conducted in eight university table tennis classes. The final sample included 393 first- and second-year undergraduate students aged 18–21 years (control group, n = 191; platform-supported group, n = 202); exact individual age was not collected. The platform-supported group used a digital-intelligent sports platform providing course learning, training assistance, competition organization, peer interaction, and achievement feedback, whereas the control group received regular PE instruction. Outcomes included basic psychological need satisfaction and frustration, self-reported physical activity, perceived exercise persistence, self-rated PE performance, perceived change in exercise frequency, and daily sitting time. Robustness analyses included class-clustered standard errors, wild cluster bootstrap tests, false discovery rate correction, and propensity score weighting. Results: The platform-supported group reported higher need satisfaction, lower need frustration, higher log-transformed physical activity, greater perceived exercise persistence, higher self-rated PE performance, more favorable perceived change in exercise frequency, and lower daily sitting time. Cross-sectional indirect-association models showed SDT-consistent pathways through increased need satisfaction and/or reduced need frustration. The direction of the primary findings remained consistent in the supplementary sensitivity analyses. Discussion: Platform-supported PE may be understood as a motivational environment rather than merely a technological tool. However, because of non-random allocation, baseline imbalance, reliance on self-report outcomes, absence of complete pretests, and lack of objective individual-level platform usage logs, the findings should be interpreted as post-intervention group differences and cross-sectional associations rather than causal intervention effects.

Objective: the purpose of this study is to explore the application of table tennis eagle eye technology and intelligent sports Bracelet in college public physical education teaching, and to evaluate its impact on students' table tennis technical level and teaching effect. Methods: through the comparative analysis of the experimental group and the control group, as well as the observation of the construction of sports growth files of the experimental group students using the bracelet and eagle eye data, the relevant data were collected and analyzed. Conclusion: the research results show that the application of table tennis eagle eye technology and intelligent sports bracelet has a significant positive impact on the improvement of students' table tennis technical level. The students in the experimental group obtained more comprehensive and objective data support through the use of seeker and bond 6, which helps them improve their technical movements and improve the accuracy of the ball. At the same time, the analysis of the bracelet and eagle eye data provides teachers with the opportunity to better understand the students' Sports Status and physical condition, as well as the basis for personalized guidance and training. Through the construction of students' Sports growth files based on bracelet and eagle eye data, teachers can better track the development trajectory of students, provide personalized guidance and training, and stimulate students' learning motivation and interest.
