Objective instruments to measure physical activity are evolving at a drastic velocity. Recent developments have allowed to classify the accelerations produced by the human body as sleep, sedentary or physical activity time with a gradient of intensities. These categories of physical behaviour coexist in the 24 hours of the day with inter-relationships that classical statistical methods fail to consider. Researchers from all around the world are investigating how to overcome this limitation at analysing physical activity temporal series by using new statistical approaches such as isotemporal substitution models, compositional data analysis, multivariate pattern analysis with partial least squares regression and/or even machine learning algorithms.

​

The present international workshop has been organized with the purpose of gathering together top experts from different countries in the abovementioned approaches to analyse physical activity data. This meeting will bring together different point of views on the state-of-the-art of physical activity data analysis, which will encourage interesting debates and, hopefully, will end up with practical recommendations on how to keep advancing to appropriately analyse physical activity data.

​

We welcome all people interested in the topic to join us in Granada (Spain), on October 21st, 2019. All attendees will have the chance to send their abstract and present their studies as oral communications or posters during the workshop.
