Comparison of flexibility training techniques (pnf) with and without electrostimulation

Abstract

The objective of this study was to analyze the effect of the Contract-Relax Agonist Contract stretching technique with (CRAC+EE) and without (CRAC) electrostimulation on the improvement and retention of active movement range (AROM) and passive (PROM) of hip in flexion, in dominant lower extremity. 34 university students were assigned to three groups: control, CRAC+EE and CRAC. AROM and PROM were evaluated before, once completed and after 2 weeks of completion the training. The training lasted 4 weeks, with 3 sessions per week.The ANOVA showed a very significant increase in AROM (p<0.001 and p<0.005) and PROM (p<0.001 and p<0.01) in both experimental groups respectively. In the retention, higher values are maintained with respect to the pre-test measurement. In conclusion, the application of CRAC++EE and CRAC improved AROM and PROM, being also effective in the retention of two types of range of motion.
