PERIOD: MAY - JUNE - JULY Measurements and sports are strongly related. The training of professional athletes is nowadays continuously monitored in order to push their performance closer to the physiological limits avoiding injuries, but also occasional or amateur sportsmen do not miss the opportunity to wear an activity tracker in order to monitor, and thus measure, speed, distance, heart rate and other physiological and non-physiological quantities. Measurements help athletes to improve their performance and this explains the growing interest in wearable sensors that are able to collect a relevant amount of data. In these simple monitoring systems the accuracy is not of primary concern, but, in races, athletes’ performance must be measured in order to quantitatively compare the participants. Here metrology plays a significant role because the results must be also compared with the results obtained by other athletes that performed the same race in a different place, at a different time and possibly with the measurements taken using different instruments exploiting different technologies, such as in the case of the Mennea 200 m Word Record that was broken after 17 years. Aim of this short course is to provide an overview of the recent measurement technologies for sport applications and to improve the student sensitivity to the metrological aspects, such as resolution, uncertainty, calibration, traceability, stability, influence quantities, definitional uncertainties, which have to be deeply understood to provide reliable measurement results.

- Revision of metrology terms and concepts o Metrology basics o vocabulary of metrology o uncertainty models and uncertainty propagation methods - Time and distance measurements in athletics o IAAF (International Association of Athletics Federations) competition rules, IAAF calibration and testing procedures o Overview of official methods, sensors, instruments and vision systems for races o Other sensors for distance measurements (GPS, IMU) and investigation about their metrological limits in sports applications - Measurements of environmental quantities that are of relevance in races: air/water temperature, WGBT temperature, humidity, wind speed. Usage of the measurement results (risk assessment, race safety, cut-off times). Role of the measurement uncertainty. - Overview of non-invasive physiological measurements and discussion about reliability and performance: heart rate, oxy and de-oxy hemoglobin concentration, VO2max.
