Abstract
During the Sardinia Innovative Boat Week, held in Olbia, Italy, in September 2024. several teams of students and university researchers, competed with self-built prototypes in a motorboats endurance race, i.e. the a Ton’s Race, lasting 4 hours and dedicated to electrically powered boats. Just before and after the race, 5 pilots: 4 males and 1 female ageing 28.8 ± 17.7 years, were engaged for several non-invasive anthropometric, psychometric, metabolic and cardiovascular tests (these latter by an Authors self-built electrical impedance cardiograph) through which was found post-race falling in the body mass (-0.6 kg) will) statistically significant reduction in ventricle preload (-21%) and heart rate (-13%). and increases in ventricle ejection velocity (23%), after load (12%), heart mechanical efficiency (23%). Experimental results outline for the first lime a biomechanical functional model of the main adaptations of the organs recruited in this new and green motor boats sports activity.
