The purposes of this study was: (1) develop a different methodology based on open-source technologies to promote quantitative movement analysis of sport skills as a regular tool in the biomechanics classroom, (2) analyze the expertise and development students’ level during the work labs and finally, (3) access the students’ engagement, motivational status and technology expertise performed in sports biomechanics. First we explore movement analysis with Dartfish software. A second software Kinovea 0.8.15 was used to extract variables for the 2D kinematical analysis and the Excel 2010 was used for data mapping and the statistics treatment (p ≤ 0,05). For the gait study results presented as an example, the statistically significant differences from the overcharge increase (+ 40% of body weight) were found on step time at 1,80 m/s (p=0,029), on the step leng at 1,25 m/s (p=0,001) and at 1,80 m/s (p=0,003), on the leng gait cycle at 1,25 m/s (p=0,011) and at 1,80 m/s (p=0,002), on the torso angle at 1,80 m/s (p=0,000) and on the hip joint angle motion at 1,25 m/s (p=0,000) and at 1,80 m/s (p=0,012). However, we conclude that overcharge (+ 40% body weight) reduce the step time and step lengthy, shorter gait cycle, increase torso frontal flexion (sagittal plane) and increase the hip joint flexion, mainly in the swing phase.The advantage of this type of classroom lab work with students, besides of having no costs, is an increase of their motivation, pushing the passing rates from 45% to 77% last year. The ability of understanding theory concepts has an exponential raise as every new concept has immediate application on the practical analysis performed with Kinovea At phase 4 we will establish the validity and reliability of all 3 softwares: Dartfish, Kinovea, and Tracker and compare sports and rehabilitation movements at 30 fps versus 60 fps
