THE STUDY OF THE MODEL INTERVAL TIME IN 400M HURDLE RACE FOR MEN
AbstractIntroduction The purpose of this study was to calculate and evaluate the equations for the model interval time of 400m hurdle race for men. The total number of samples were 651. Interval time was defined as the time from starting point to the first touchdown after hurdling, and between each touchdown there-after. The samples were divided into 8 groups according to performance time. The performance range were 48.79- 59.45sec. 11 equations for each group were calculated from the samples. RESULTS High correlation between each interval time and performance time was obtained. the correlation coefficient between 8th i n t e r v a l t i m e and performance was the highest in particular. Performance time correlated with the 2-9th interval time in group A (48.48- 50.99,n=41). Performance time correlated with the 2,3,5th interval time in group B (51.1 3- 51.97,n=55). Performance time correlated with the 5-8th interval time in group C (52.00- 52.99,n=I 14). Performance time correlated with the 3th,8-10th interval time in group D(53.00 -53.99,n=143). Performance time correlated with the 5-8th interval time in group E (54.00- 54.98,n=126). Performance time correlated with the 6-8th interval time in group F (55.00- 55.99,n=82). Performance time correlated with the 7-8th interval time in group G (56.02- 56.94,n=32). Performance time correlated with the 8-10th interval time in group H (57.08-59.45,n=48). CONCLUSION The performance time correlated significantly with the 8th interval time in 7 groups(A,C,D,E,F,G,H). Furthermore performance time corelated with the 7th and 9th interval in 5 groups. Therefore, it is suggested that performance correlates highly with the latter half of race, especially the 8th interval. In conclusion, in order to improve overall performance, it is important to improve the performance between the 7th and the 9th interval.
