Sažetak
The 400 m hurdle is a very complex track and field event. Since the velocity curve of different runners’ quality is well known for some other sprint events at the additional knowledge about velocity curve of 400 m hurdles elite runners is a prerequisite for improvement of training methods related to the quality and development of 400 m hurdles running/events. The aim of this study was to determine the 400m hurdles running dynamics of male athletes as well as to determine relations of all the segments of competition activity in 400 m hurdles with the (achieved) respective competition results. The study was conducted on a sample of 156 elite hurdle runners who participated in the World Championship and the Olympic Games from 1968 to 2009. All data were taken from the publically announced official data and were given to the athletes, coaches and media. Dynamics of sprinting over 400m hurdles have been observed across ten segments (achieved time at each hurdle). Descriptive statistics were calculated on the 10 segments of running dynamics and on achieved final results. Multiple regression analysis was used to determine relations between all the segments of competition activity in 400m hurdles (independent variables) with the achieved competition results (dependent variable). The results showed that the analysed time parameters of rhythm/dynamics run can explain 97% of the total variance in running the 400 m hurdles. The following variables had the dominant influence on the overall achieved competition results: achieved time at the 1st (p=0.02), the 3rd (p=0.05), the 8th (p=0.06), the 9th and the 10th hurdle (p=0.00). Since we used data from the high ranked competitions, according to the IAAF rules, the sample used for the purpose of this study can be treated as highly valid. It seems quite logical that times achieved at the last three hurdles in the race have statistically significant influence on competition result. Statistically significant relations Training and Testing 714 19th Annual Congress of the European College of Sport Science obtained at the 1st and the 3rd hurdle points to the importance of sustainability of running rhythm from the beginning of the race onwards. It is possible to speculate that athletes who are able to maintain good rhythm during the race with as little oscillations as possible will have smaller number of strides between the hurdles as well as better performance time at each hurdle/segment.
