Abstract

Seven division I collegiate steeplechase athletes, four males and three females, were videotaped at 60 Hz from a side view as they hurdled a barrier during a 3000-meter steeplechase race. Data from seven barrier negotiations were recorded for each athlete. Kinematic variables including approach velocity, lead leg take-off angle at the knee joint, clearance height, flight time, flight displacement and exit velocity were determined using the Ariel APAS software. Sit-and-Reach flexibility and split stretch flexibility were measured after the race. ANOVAs with repeated measures were used to determine differences between each kinematic variable from all seven laps, and with laps as the repeated factor, within subjects. There were no statistically significant results from any of the ANOVAs. This is indicative of consistent hurdling performance from lap to lap. Pearson product correlation coefficients were calculated between each kinematic variable and each flexibility parameter. There were statistically significant negative correlations between flight displacement and split stretch for males ( r = -0.976, p = 0.024), between exit velocity and split stretch for males ( r = -0.970, p = 0.030), and between approach velocity and Sit-and-Reach for females ( r = -0.998, p = 0.039). Based on these findings, there is no evidence to support that improving Sit-and-Reach will lead to improved approach velocity, take-off angle, clearance height, flight time, flight displacement or exit velocity for either male or female athletes. Improving split stretch flexibility led to longer flight displacements and faster exit velocities in the male subjects.
