Abstract

The purpose  of   this study   was  to compare  the  biomechanical  performance  of   110- meter hurdles in  the  Iran  with   world  and  Olympic  elite  runners.  For  this  study, 6 elite Runners  of  the  adult  national   team  with   the  age,  weight   and   height :  21 ±  2.25  yr,  74±1.4 kg   and  184.9±4.5 cm  were  selected. Also, there were 6 elite  runners  of  world competitions  with  age,  weight  and  height  24± 2.75 yr, 79±3.2 kg  and   185.4±3.8 cm, and 6 elite  runners of the  Athen Olympic  competitions  at 2004 with  the age, weight  and height : 24±2.9 yr, 81±2.37 kg  and 185.1  ± 3.4 cm. The  information about biomechanical   performance of  subjects  was obtained  via  film-taking  and  through advanced methods  and  devices. The data obtained were analyzed by using descriptive statistics. Results showed that contact time of foot with ground at moment of take–off, flight time to  pass  foot   of   hurdle, horizontal  displacement of  center of  mass  in  peak  and  land displacement were  greater in elite  national runners. However, horizontal velocity of the mass center at moment to land was less  in  the world and Olympic  runners. On  other hand, there was not  a significant  difference between the world  and Olympic  runners. It can be concluded from the study that the better technical and biomechanical performance in the world and Olympic runners caused better records.
