[Purpose] The maintenance effects of proprioceptive neuromuscular facilitation (PNF) special techniques were investigated using the reaction time (RT). [Subjects] The subjects were 40 healthy adult males. [Methods] The subjects were randomly divided into 4 groups of 10 persons, 3 groups of PNF techniques, joint exercises classified according to changes in speed, of initial stretch (IS), stabilizing reversal (StR), and combination of isotonics (CI), and an elbow flexion group, which executed the respective movements. To investigate the maintenance effect, RT was measured 7 times, immediately before the interventions, and at 0, 5, 10, 15, 20 and 30 min afterwards. [Results] In the IS and StR groups, RT was found to be shorter than before the intervention, until 10 min after the intervention, and in the CI group, it was shorter than before, the intervention until 15 min after the intervention. In the elbow flexion group, no significant differences from pre-intervention were found in the post-intervention RT. [Conclusion] The compound movement groups showed post-intervention maintenance effects lasting for 10~15 min, suggesting the utility of compound movements as physical therapy techniques in clinical applications.
