Gender Differences And Biomechanics In The 3000m Steeplechase Water Jump, Kassi R. Andersen, Bryan K. Lindsay, Iain Hunter Jun 2008

Gender Differences And Biomechanics In The 3000m Steeplechase Water Jump, Kassi R. Andersen, Bryan K. Lindsay, Iain Hunter

Faculty Publications

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 …

Ground Reaction Force Differences Between Running Shoes, Racing Flats, And Distance Spikes In Runners, Suzanna Jean Logan Jun 2007

Ground Reaction Force Differences Between Running Shoes, Racing Flats, And Distance Spikes In Runners, Suzanna Jean Logan

Theses and Dissertations

To measure the differences in ground reaction forces between running shoes, racing flats, and distance spikes, twenty intercollegiate distance runners ran across a force plate at 6.7m/s (for males) and 5.74m/s (for females) in each of the three types of shoes. In order to control for differences in foot strike, only subjects who had a heel strike were included in the data analysis (N=16). Repeated-measures ANOVA and Tukey's post-hoc test (p<0.05) revealed loading rate and impact peak to be significantly increased in the flats and spikes compared to running shoes. Stiffness in spikes was significantly higher than in running shoes. Stance time in spikes and flats was decreased. These results can be used to better inform competitive runners, coaches, and trainers of the risks and performance benefits when determining the frequency and duration of the use of competitive footwear in training.

The Effects Of Wearing A Cooling Vest During The Warm-Up On Long Distance Interval Training, Andrew Robert Tegeder Aug 2006

The Effects Of Wearing A Cooling Vest During The Warm-Up On Long Distance Interval Training, Andrew Robert Tegeder

Theses and Dissertations

Purpose: Reducing body temperature before exercise is called precooling. Past research suggests that reducing body core temperature (Tc) slightly can result in improved running performance. This study evaluated the effects that warming up, while wearing a cooling vest prior to an interval workout, had on Tc, and interval time in long-distance runners. Methods: Nineteen healthy male collegiate cross-country runners were recruited for this study. Each subject warmed up and exercised under two different conditions: (a) an experimental condition in which subjects wore a Nike PreCool® ice vest during warm-up and (b) a control condition. Subjects performed a warm-up followed by …

Steeplechase Barriers Affect Women Less Than Men, Tyler D. Bushnell, Iain Hunter Jun 2006

Steeplechase Barriers Affect Women Less Than Men, Tyler D. Bushnell, Iain Hunter

Faculty Publications

Women began contesting the 3000 m steeplechase during the 1990’s using barriers of different dimensions than men. Whenever a new event is introduced for women, consideration should be taken as to whether different technique or training methods should be utilized. This study investigated three aspects of hurdling technique: 1) Differences in the ratio of the landing step to the penultimate step between men and women around each non-water jump steeplechase barrier, 2) differences in step lengths between the four non-water jump barriers, and 3) changes in the step lengths around the barrier throughout the race. The step lengths around the …
