| Since 1996, women have been competing in the 3000m steeplechase
race internationally. Whenever women and men both compete in similar events
with different equipment (the barriers are lower for women) consideration
should be given as to how techniques should be coached differently. This
study investigated the differences in water-jump technique between men and
women after accounting for differences in running speed and which techniques
led to maintenance of race pace through the water-jump. Eighteen men and
18 women were filmed at two major track and field meets during the 2004
season. Peak Motus 8.2 was used to digitize all seven jumps from each athlete.
Various characteristics of water-jump technique were measured or calculated
and compared using two multiple linear regressions (one for men and one
for women) to determine which characteristics led to maintaining race pace
speeds through the water jump obstacle. Repeated measures ANOVA was used
to determine any differences between men and women in the measured characteristics
of technique.Velocity through the jump divided by race pace was predicted
very well by approach velocity and landing distance for men and women. Other
characteristics of the movement were non-significant. Differences between
genders were found in: approach velocity, take-off distance, landing distance,
push-off angle, velocity through jump, and exit velocity. Men and women
steeplechasers must focus on approach velocity and landing distance to complete
the water-jump close to their race pace. Coaches need to consider many characteristics
of technique that differ between men and women.
