The goal of this pilot study was to investigate the capabilities of the e-Kayak system, a multichannel digital acquisition system specifically tailored for flatwater sprint kayaking application. e-Kayak allows the synchronous measure of all the parameters involved in kayak propulsion, both dynamic (including forces acting on the paddle and footrest) and kinematic (including stroke frequency, displacement, velocity, acceleration, roll, yaw, and pitch of the boat). After a detailed description of the system, we investigate its capability in supporting coaches to evaluate the performance of elite athletes\u2019 trough-specific measurements. This approach allows for a better understanding of the paddler\u2019s motion and the relevant effects on kayak behavior. The system allows the coach to carry out a wide study of kayak propulsion highlighting, and, at the same time, the occurrences of specific technical flaws in the paddling technique. In order to evaluate the correctness of the measurement results acquired in this pilot study, these results were compared with others which are available in the literature and which were obtained from subjects with similar characteristics.<\/jats:p>","DOI":"10.3390\/s20020542","type":"journal-article","created":{"date-parts":[[2020,1,20]],"date-time":"2020-01-20T04:27:09Z","timestamp":1579494429000},"page":"542","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["A Pilot Study on the e-Kayak System: A Wireless DAQ Suited for Performance Analysis in Flatwater Sprint Kayaks"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2328-4793","authenticated-orcid":false,"given":"Vincenzo","family":"Bonaiuto","sequence":"first","affiliation":[{"name":"Sport Engineering Lab, Department of Industrial Engineering, University Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6322-7761","authenticated-orcid":false,"given":"Giorgio","family":"Gatta","sequence":"additional","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47037 Rimini, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0904-634X","authenticated-orcid":false,"given":"Cristian","family":"Romagnoli","sequence":"additional","affiliation":[{"name":"Sport Engineering Lab, Department of Industrial Engineering, University Rome Tor Vergata, 00133 Rome, Italy"},{"name":"Department for Life Quality Studies, University of Bologna, 47037 Rimini, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Boatto","sequence":"additional","affiliation":[{"name":"APLAB, 00196 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nunzio","family":"Lanotte","sequence":"additional","affiliation":[{"name":"APLAB, 00196 Roma, Italy"},{"name":"Department of Human Sciences and Promotion of the Quality of Life, San Raffaele Roma Open University, 00166 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe","family":"Annino","sequence":"additional","affiliation":[{"name":"Sport Engineering Lab, Department of Industrial Engineering, University Rome Tor Vergata, 00133 Rome, Italy"},{"name":"Department of Systems Medicine, University Rome Tor Vergata, 00133 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"355","DOI":"10.1037\/0033-2909.95.3.355","article-title":"Knowledge of results and motor learning: A review and critical reappraisal","volume":"95","author":"Salmonia","year":"1984","journal-title":"Psychol.
