In order to improve the control ability of the human body in the process of physical training, it is necessary to carry out the inverse simulation analysis of the physical training process and establish the process control model of the physical training. The complex problem of high-dimensional spatial motion planning involved in physical training is decomposed into a series of sub-problems in low-dimensional space, and the inertial attitude parameter fusion is carried out according to the position and pose state of the human body in the end of the workspace during the process of physical training. The design of sensor node and base station in the system can realize real-time collection of motion parameters of motion collectors. The multi-dimensional control of physical training process is carried out by fuzzy constraint and inverse integral control, and the attitude parameters of human body are adjusted by means of mechanical analysis model and inertial parameter analysis method. The simulation results show that the inversion simulation control has better convergence, higher control quality, and better inverse simulation performance in the process of physical training, which can effectively guide physical training and improve the effect of physical training.

Volleyball Players

Physical competition is becoming the new focus of volleyball in an increasingly perfect technical and tactical system. Unfortunately, poor physical fitness is a recognized weakness of volleyball players and a critical factor that has restricted the rapid development of volleyball for a long time. This paper proposes a grey Markov model-based approach to improve the evaluation ability of physical training. It aims to construct an empirical analysis model by combining statistical results and analyzing the evaluation parameters for physical training effects. The sports parameter analysis method is adopted to establish an optimal model of these parameters. Finally, a distribution model of moments of inertia combined with fuzzy information fusion’s feature extraction method is proposed for the distributed reconstruction of physical training. The optimization of training effects based on parameter optimization and construction of a grey Markov model enhances the physical training of volleyball players.

Military-applied sports are effective means of physical, moral and psychological training of servicemen for combat activities. A single universal program for training cadets by means of military pentathlon is not described in the special literature. The goal is to summarize the experience of building the training process in military all-around in military universities. 40 coaches of national teams in military pentathlon of 7 universities of Ukraine were surveyed. Results. Physical training of cadets by means of military pentathlon contributes to the formation of their professionalism - it improves applied skills, physical and functional readiness for combat operations. Sports result in military pentathlon to the greatest extent depends on the level of development of athletes' aerobic and speed-power endurance, as well as speed-power qualities. Most often, an obstacle course and throwing are combined in one workout. Regardless of the training period, most of the time is devoted to cross training. Conclusions. The opinions of the coaches on the key issues of building the training process differ significantly, which means that there is no single training methodology for military pentathletes in the universities of Ukraine. Research on the establishment of a scientifically grounded ratio of training volumes of military pentathletes is urgent.

The article considers the increase of special physical training, in particular, speed endurance in children of middle school age who are engaged in swimming. Increasing speed endurance is currently one of the most pressing issues in classes with children in sports sections, which is extremely acute in modern swimming in general. At the beginning of the study, a test was performed, which showed no significant differences between the performance of boys in both groups, ie at the beginning of the experiment they had the same level of development of functional abilities, including speed endurance. In the course of the research the technique aimed at the development of speed endurance in middle school children was used. At the end of the experiment, it was found that the performance of the swimmers of the experimental group was significantly higher, compared with the control group (62.1 ± 0.6s) in swimming 2x50m. It was 56.2 ± 0.2 s. The significance of the differences between these indicators was 9.33. In the 25 m swim without the participation of the legs, the result of the swimmers of the experimental group was 20.3 ± 0.8 s, and in the control - 25.8 ± 1.1 s. Significance of differences was established between them (t = 4.04). There is a positive growth of sports results of young swimmers. A high increase in results was found in the Cooper test - 19%, swimming in the distances of 25 meters - 10%, 100 meters - 9%, 800 meters - 9% and 200 meters - 8%. The influence on the functional state of children during the experiment, the use in the training process of exercises that are not specific to swimmers and aimed at improving the level of development of functional abilities, which created the conditions for the most effective special physical training.

Purpose This study aims to address the challenge of training a detection model for the robot to detect the abnormal samples in the industrial environment, while abnormal patterns are very rare under this condition. Design/methodology/approach The authors propose a new model with double encoder–decoder (DED) generative adversarial networks to detect anomalies when the model is trained without any abnormal patterns. The DED approach is used to map high-dimensional input images to a low-dimensional space, through which the latent variables are obtained. Minimizing the change in the latent variables during the training process helps the model learn the data distribution. Anomaly detection is achieved by calculating the distance between two low-dimensional vectors obtained from two encoders. Findings The proposed method has better accuracy and F1 score when compared with traditional anomaly detection models. Originality/value A new architecture with a DED pipeline is designed to capture the distribution of images in the training process so that anomalous samples are accurately identified. A new weight function is introduced to control the proportion of losses in the encoding reconstruction and adversarial phases to achieve better results. An anomaly detection model is proposed to achieve superior performance against prior state-of-the-art approaches.

Existing Bridges

This paper aims to put forward a new method of strengthening the existing bridges with narrow decks and low bearing capacity to overcome the high cost and pollution problems in dismantling them. The method, strengthening bridges by built stringers and cross beams, is by widening some parts of a bridge. Based on the basic theory of finite element, we have set up an analysis model of strengthening the bridges by widening, which helps to demonstrate the rationality of this method. Meaningful conclusions have been drawn from the parameter analysis of the rigidity of the new widening stringers, the rigidity of the new cross beams and the relative settlement of the new and the old foundations. This method can be referenced by the reinforcement and maintenance of medium and small bridges.

RUNNING A MARATHON IS ALL ABOUT PUSHING THE human body farther than its meant to go: Beyond the point where glycogen is available, beyond the point where muscles cease complaining and just plain cramp up. Doing a Google search on “pushing yourself” yields all kinds of references to running, training, triathlons, just about any type of physical training imaginable.
