Instrumented Rowing Machine for Optimized Training

Indoor training of rowers is mainly carried out on rowing machines. Modern rowing machines are equipped with a small computer that allows to register both the effort done by the athlete and the covered distance. However, the effort is measured indirectly and it is not possible to determine, within the rowing movement, how this effort is distributed. Moreover, no information is provided on the forces exerted on the footrests, thus preventing trainers to determine the configuration that maximizes performances. The present work deals with the re-design of a rowing machine able to accommodate force sensors for measuring the time histories of the traction force at the handlebar, the two force components on the footrest (taken directly form the boat so that settings can be ported immediately), the vertical force and the displacement of the seat. Preliminary tests for assessing the athletes’ performances are also presented.
