Ballistic and proprioceptive neuromuscular facilitation (PNF) through hold-relax technique are amongst the most used stretching methods in the clinical practice. Few studies have explored for how long alterations in range of movement (ROM) dependent upon the stretching intervention have lasted or compared the effi cacy of diff erent types of stretching within a given load on this time. Th erefore, the aim of this study was to compare ballistic and PNF hold-relax stretching and their eff ects in the hamstrings musculature related to ROM gain and its maintenance after 24 hours. 19 healthy youngadults participated on the study. Th e ROM evaluation was carried out through photogrammetry before, immediately after and after 24 hours the intervention. Th e stretching methods were randomly assigned in one session. It was possible to verify, through the results, that both techniques improved ROM immediately after intervention (p = 0,001 for ballistic and p = 0,001 for hold-relax) and the eff ects were maintained after 24hours intervention (p = 0,023 for ballistic and p = 0,022 for hold-relax). However, when comparing both methods, no diff erence was found about the ROM gained. It has been then confi rmed the equal effi cacy of both methods for improvement and maintenance of ROM.
