This study took the ergonomics design course as an example to propose a design teaching model of multidisciplinary participatory design (MPD), and investigated the effects of this teaching model on the engineering design behavior of college students. We used lag behavior sequential analysis to compare the design behaviors of three student groups: a participatory design (PD) experimental group, an MPD experimental group, and a control group. The results of the study show that (1) students in the PD experimental group had 13 significant sequential engineering design behaviors, students in the MPD experimental group had 10, and students in the control group had only seven. The engineering design behaviors of the experimental groups were more diversified than those of the control group. (2) The three groups of students had a small number of significant design behavior transfers in the engineering design process, indicating that the students’ sequential design behaviors between two different design activities were insufficient. We concluded by detailing the pros and cons of using the MPD teaching model based on the results of this study, and hopefully by providing a reference for teaching engineering design.

Based on the concept and definition of “integration of sports and medicine,” this paper analyzes the current situation of the integration, where it lacks innovative physical education curriculum content and physical education teachers with conventional medical professional knowledge; in addition, physical education disciplines with medical characteristics are not highlighted. Therefore, relevant measures are put forward for reference and discussion.

Introduction: Table tennis is demanding in terms of athletes’ physical fitness and muscular responsiveness. Excellent physical fitness is important to ensure a high technical level. It can also play an essential role in injury prevention. Objective: Explore the correlation between table tennis players’ movements and their displacements. Methods: Volunteer professional competitors underwent a private 16-week quality speed training program. In this experiment, athletes had their speed analyzed before and after training. Mathematical and statistical analyses were performed on the collected data. Some discussions are made to improve the reflex ability of the athletes. Results: The table tennis players’ physical fitness and action response capacity were explored. After physical exercise, the players’ reflex ability improved. There were statistically significant differences in the data (P<0.05). Conclusion: The results show that special training improves athletes’ reaction speed, endurance, strength, coordination, and flexibility. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
