Abstract

    The purpose of this study is to clarify the race pattern and change characteristics of race pattern in the different recording from Inter-High School competition (IH) to National Sports Festivals in Japan (NS) in high school 400m hurdles. The races from IH and NS in the years 2008, 2009, 2011, 2012, and 2015 were videotaped, panning from the start to the finish. Each time at touchdown immediately after hurdling from the start, and each section number of step were obtained. Each parameter between IH and NS was compared in all subject and type of race patterns in IH. Each section was defined as follow: Section1 (S1) was from start to 2th hurdle (H2). S2 was H2-5. S3 was H5-8. S4 was H8- finish. Our results were showed as follow.
    1) Type A (speed maintenance: n=9) was faster in S2 (H1-5), and higher in the rate of deceleration in NS.
    2) Type B (speed reduction: n=18) was faster in S4 (H8-Run in), and lower in the rate of deceleration in NS.
    3) The performance of the Type A is superior to that of the Type B. These results indicate that the section should improve the speed different for each type of race patterns.
