The aim of the study was to establish the level of learning and performance of the crawl technique, taking into account the hydrodynamic index and the anthropometric characteristics, as a result of practical swimming lessons, with students of first year, specialization physical education and sport. The Experiment was conducted during the academic year 2015-2016 and included a total of 18 students, boys between the ages of 19-22 years, first year, physical education specialization. Motor skills tests which were applied targeted: the length of facial floating with a push from the wall and the length of time performed on 25 metres distance in the crawl swimming stroke. Anthropometric measurements consisted in the determination of the hydrodynamic index taking into account the biacromial and bitrohanterial diameters and the difference between the wingspan of the arms and height. At the end of the study the floating facial test has recorded a progress of 0.29 m and the test concerning the execution technique of the crawl stroke has recorded a progress of 1.65 h, which in correlation with the hydrodynamic and anthropometric indices led to the conclusion that this is due, in particular, to the execution technique corrected by the methodology applied to the classes of practical works at swimming discipline. Performing practical lessons at the swimming subject unfolded over the course of a university semester reaches the goals of improving knowledge of teaching methodology to a great extent but it equally shows a deficit at the level of physical performance of the future specialists. Following the application of the selected means of action and the choice of an efficient teaching strategy in both tests which aimed at the execution technique indices of the crawl stroke a significant progress was made.
