Analysis of GPS and UWB positioning system for athlete tracking

In recent years, wearable performance monitoring systems have become increasingly popular in competitive sports. Wearable devices can provide vital information including distance covered, velocity, change of direction, and acceleration, which can be used to improve athlete performance and prevent injuries. Tracking technology that monitors the movement of an athlete is an important element of sport wearable devices. For tracking, the cheapest option is to use global positioning system (GPS) data however, their large margins of error are a major concern in many sports. Consequently, indoor positioning systems (IPS) have become popular in sports in recent years where the ultra-wideband (UWB) positioning sensor is now being used for tracking. IPS promises much higher accuracy, but unlike GPS, it requires a longer set-up time and its costs are significantly more. In this research, we investigate the suitability of the UWB-based localisation technique for wearable sports performance monitoring systems. We implemented a hardware set-up for both positioning sensors, UWB and the GPS-based (both 10 Hz and 1 Hz) localisation systems, and then monitored their accuracy in 2D and 3D side-by-side for the sport of tennis. Our gathered data shows a major drawback in the UWB-based localisation system. To address this major drawback we introduce an artificial intelligent model, which shows some promising results

Análise do impacto da tecnologia na gestão do tênis de campo

Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Faculdade de Economia, Administração e Contabilidade, Departamento de Administração, 2018.O avanço da globalização e da tecnologia são fatores relevantes para o crescimento de organizações esportivas e, com isso, torna-se um ambiente cada vez mais profissional e competitivo, onde atletas que utilizam tecnologias de alta qualidade tendem a se sobressair quanto ao seu nível técnico com relação aos seus concorrentes. O presente estudo busca analisar como a tecnologia impacta os profissionais no tênis de campo. Por meio de uma revisão bibliográfica sistemática, com duas etapas de filtragem de obras relacionadas ao esporte estudado, foram analisadas 57 obras a fim de discorrer sobre como a tecnologia impacta na tomada de decisão de profissionais nos treinamentos e táticas; arbitragem; gestão de organizações e eventos relacionadas ao tênis e espectadores. Concluiu-se que por meio de tecnologias como o Hawk-Eye, o Business Intelligence e a Internet das Coisas, a gestão das frentes estudadas auxiliam treinadores, atletas e gestores para maximizar o desempenho de todos no tênis

Unravelling tennis performance:creating monitoring tools to measure and understand technical and tactical skills

The key in elite tennis performance is suggested to be the combination of outstanding technical and tactical skills. However, little is known about which specific skills are important to progress towards elite tennis performance. Moreover, there are no reliable, valid and feasible tools to assess technical and tactical skills in youth tennis players. Therefore, in this thesis, tools with sufficient psychometric properties were developed to measure technical and tactical skills in a tennis-specific context - contributing to both scientific and practical purposes. An on-court tennis test was developed to assess technical skills based on accuracy (target areas), ball speed (radar system) and percentage errors. A new instrument with closed-ended questions was designed to examine tactical skills, in particular ‘Anticipation and positioning’, ‘Game intelligence and adaptability’, ‘Decision-making’, and ‘Recognizing game situations’. Our studies showed that outstanding technical skills, especially accuracy under increased task complexity (i.e. high temporal and cognitive pressure), were considered essential to progress towards elite tennis performance. Findings of this thesis also suggest that these technical skills continue to develop in adolescence in a group of youth talented tennis players. From a practical perspective, the tools created in this thesis are valuable for coaches and players to enhance tennis performance. In addition to monitoring the progress of players, tools can assist in identifying relative strengths and weaknesses of players as well as provide essential information about underlying skills that require most attention to progress towards elite performance
