The development of motor qualities represents a constant challenge for specialists in the domain of physical education. The general competences from the new Physical Education school curriculum for the 3rd and 4th grades focus on improving motor quality manifestation indices in relation to the individual possibilities of pupils belonging to this age group. In the present paper, we aimed at presenting the results regarding the improvement of the speed motor quality by using movement games and relays. We used 5 movement games and 5 relays, which concentrated on developing speed. In order to test the results obtained within the physical education classes we used the 25-metre sprint, the race starting from a standing position. The results recorded in the final tests proved that the use of movement games and relays had a positive effect on the improvement of the speed motor quality manifestation indices. The experimental group obtained an average value of performance for the tested trial of 6.07 seconds whereas the control group obtained an average value of performance of 6.21 seconds. Therefore, we can assert that the obtained results prove the practical efficiency of movement games and relays.
