Aim: determine the use of the technology associated to the control of strength training in teams of the Spanish roller hockey. The following aspects were examined: physical conditioning coaches profile and the percentage of the teams than utilize an encoder, to measure the displacement time of the bar, and the Optojump system. Methods: A survey was administered to the responsible of the physical conditioning preparation of each team by means of personal interview. The response rate was 83.3%. Results: There were differences between categories in the utilization of the encoder (21.4 vs 12.5%) and of the Optojump (35.7 versus 25.0%). The two vertical jump height tests more used were the countermovement jump (CMJ) (33.9%) and the squat jump (SJ) (20.5%). Due to the variability of practical applications of the Optojump and especially of the encoder, and the difficulty to control numerous parameters by means of another methodologies. Conclusion: the results of this study show, that at least in great part in the teams examined exist absence of scientific control of the strength training. The poor scientific formation of the physical conditioning coaches and various aspects associated to the team sports, requirements of the competition calendar, variability of performance factors and the numbers of players can explain these results.
