Sports medicine and textiles have a lot to share both to facilitate athletes during performance and in the recovery period during rehabilitation. Professor Davide Susta and the canoe polo technician Antongiulio Cusmai lead us to discover the role that textiles can play in sport. In this episode we talk about functional textiles, that is, those materials that, on the one hand, help to contain fatigue during physical exertion and, on the other, encourage a better technical gesture or better performance by giving balance to the limb in use.
