The purpose of the paper is comparing the rowing results in different aeroand hydrodynamics conditions. We analyzed the winners’ results of the single sculls (1x) men finals at the Olympic Games regattas from Sydney to Tokyo. We used precise weather hour diary and satellite maps to reconstruct the exact weather race conditions.We found data on the sport results and parameters of the rowers on the official websites of the competitions and the WorldRowing website. The created physical and mathematical model of the weather conditions influence is based on the second law of mechanics and includes 22 variables which characterise environment and features of the rowing biomechanical system. The physical and mathematical model was implemented in the form of a computer application. The computer application made it possible to accurately assess the preparedness of athletes by clearing the distance time off the environment influence. The pure characteristic time allowed comparing the results obtained in different weather conditions. Calculation reveals that the weather conditions have an effect on race time significantly. The weather influence on Olympic race was in the range of - 10.10 to +5.94 seconds. The presented approach allows to register world and Olympic records for the first time in rowing history.
Introduction. The health of schoolchildren is the foundation for the educational process and the key to success in future work activities. The current level of development of technology and information technology allows you to bring health monitoring to a new, higher quality level. Purpose of the study: on the basis of a comparison of various historically established approaches to assessing the health of schoolchildren, to identify the main development trends and promising technologies suitable for determining the integral indicator of the health of schoolchildren. Research methodology and techniques. The research is theoretical. To search for information about innovative technologies, we analyzed scientific articles in Russian and English, taken from scientometric databases. As a result, we selected 14 technologies that were more consistent with the requirements of minimum time consumption, distance and invasiveness. Results. Technologies used in biomechanics, medicine, forensic science, navigation together can make it possible to comprehensively assess the psychological, neurodynamic, motor and energy components of schoolchildren's health. The most promising systems for assessing the health of schoolchildren are the following systems: an image processing system (technology for detecting and recognizing faces, technology for recognizing facial expressions and gestures), an optoelectronic measuring system (motion capture technology), an internal thermometry system (acoustothermometry), a navigation system, an electromagnetic measuring system, system of content analysis of Internet traffic, strain-dynamometric system, as well as neurotechnological system. The proposed approach requires significant information resources for the accumulation and automated processing of large amounts of information in a single analytical centre. The use of artificial intelligence algorithms will allow detecting hidden relationships of health indicators, assessing risks and giving personalized recommendations. On the basis of the information collected, it is planned to create an electronic passport of schoolchildren's health with further integration of this module into the domestic educational complex of an electronic student's diary.
Introduction: One of the most important physical education tasks in school is to learn motor actions. Biomechanical technologies can promote to this process. A school lesson is different from a sports training, so it is necessary keep in mind its specifics. The purpose of the article is to analyse the existing professional biomechanical complexes for their suitability for use in physical education classes. Methods: We studied articles on sports biomechanics and selected 20 professional biomechanical complexes. These complexes can be divided into four technological groups: Optoelectronic Measurement Systems (OMSs), Electromagnetic Measurement Systems (EMSs), Image Processing Systems (IMSs), Inertial Sensory Systems (IMUs). Besides that, we identified 10 crucial categories to estimate opportunity to use biomechanical complexes in school lessons: cost, complexity of setting up and using, assistance need, portability, universality, room volume, construction traumatic, place for using, promptness, volume of data. Thus, each complex was evaluated according to 10 criteria. The biomechanical complex was excluded from further consideration if it got a critical limitation at least one of the criteria. Results: None of the professional biomechanical complexes can be considered suitable for use in physical education classes. As alternative we propose using free biomechanical software and smartphone camera with slow-motion caption.
