In the context of modern sport, athlete training and approaches to optimize performance are constantly evolving, requiring in-depth knowledge of human movement science to achieve optimal efficiency. The EOPS Master's degree trains human movement scientists able to handle complex situations specific to sports field with the goal to optimize training and preserve the health of athletes. From September to March in Master 1 and from September to January in Master 2, students follow courses in the form of lectures, tutorials and practical work at the Evry university, Orsay university and Racing Club 92 (Plessis-Robinson). Following this teaching period, students complete an internship in a research laboratory, a sports or hospital structure. The subject of the internship is expected to be related to the Master's courses, typically training, performance optimization or athlete health. During this internship, students are individually monitored by a researcher, possibly accompanied by a professional from the socio-economic world (depending on the internship location). The duration of the internship is around 200 hours in Master 1 and 300 hours in Master 2. The internship gives rise to a report written according to the scientific standards and defended in front of a jury composed of researchers and professionals.
