In sports training, flexibility is possibly the physical capacity that demands less work and whose results generate the greatest controversy. However, different stretching techniques are implemented as a method for injury prevention. This study sought to determine jump power changes after the implementation of two flexibility training programs in futsal players. We conducted an experimental study with pre- and post-intervention evaluations of two flexibility training programs for the ischiosural muscles using proprioceptive neuromuscular facilitation and the foam roller. The futsal players' jumps were evaluated with electromyography of the ischiosural muscles and flexibility tests before and after the intervention. The results showed a significant increase in height in the countermovement and Abalakov jumps in the group using the foam roller while the neuromuscular facilitation technique resulted in a statistically significant (p<0.05) increase in the Abalakov and the right unipodal jumps compared to the control group. We found a decrease in the electromyographic activation of the semitendinosus and right femoral biceps muscles during the squat jump after the intervention. In conclusion, adequate planning and structuring of flexibility training with techniques such as the foam roller and the proprioceptive neuromuscular facilitation improved the muscle contraction efficiency and the jumping ability in indoor soccer players from the city of Popayán. © 2019.
