Sport research. Athlete taking part in sport science research. He is being filmed by a video camera, wearing reflective patches (white) that make it easier to translate his movements into a computer model. This technology is known as motion capture. The goal of the research is to analyse his movements and allow him to improve his performance at the starting blocks.
