摘要：Take off is considered as a most important phase in Triple jump. The aim of this research was to compare the selected kinematic parameters of three take off phases of triple jump performed by elite Iranian and World-class athletes. The participants were five elite Iranian triple jumpers (mean record: 15.4±0.8 m) who had participated in the final stage of track and field competition held in Tehran. Performances of these athletes were recorded using three cameras and three best performances of each jumpers were analyzed. Results show the significant differences in horizontal velocity of Hop and Jump take off phases and also a significant difference in support time of Step take off phase. All these parameters are lower from International values. Therefore, attention to design the exercises for increasing the muscular strength and neuromuscular coordination is recommended to coaches.
