The Effect Of Foot Strengthening Exercise On Dynamic Function Of The Medial Longitudinal Arch In Runners: A Preliminary Report, Jarom Bridges
The Effect Of Foot Strengthening Exercise On Dynamic Function Of The Medial Longitudinal Arch In Runners: A Preliminary Report, Jarom Bridges
Theses and Dissertations
Therapeutic exercise has previously been shown to alter the static height of the medial longitudinal arch (MLA). It is still unknown, however, if these effects carry over into dynamic activities. PURPOSE: To determine if an 8-week foot strengthening exercise program increases static arch height and reduces vertical deformation of the MLA during mid-stance in running.METHODS: Thirty-four recreational runners (17 males, 17 females) have completed this ongoing study (age 24.06 ± 3.61 years, body mass 68.63 ± 12.95 kg, and height 173.34 ± 9.54 cm). To date, 22 subjects have been assigned to the control group (8 weeks of normal running) …
Steeplechase Hurdle Economy, Mechanics, And Performance, Sarah Ingebretsen
Steeplechase Hurdle Economy, Mechanics, And Performance, Sarah Ingebretsen
Theses and Dissertations
Research surrounding the steeplechase is scarce, with most research focusing primarily on how biomechanical factors relate to maintaining running speed while crossing barriers. One area that has not been well explored is the relationship between biomechanical factors and hurdling economy. The purpose of this study was to investigate how performance times and biomechanical variables relate to hurdling economy during the steeplechase. This was accomplished by measuring running economy of collegiate and professional steeplechasers while running with and without hurdles. Biomechanical measures of approach velocity, take-off distance, clearance height, and lead knee extension while hurdling, as well as steeplechase performance times …
Kinematic Changes During A Marathon For Fast And Slow Runners, Maggie Man-Yee Chan-Roper
Kinematic Changes During A Marathon For Fast And Slow Runners, Maggie Man-Yee Chan-Roper
Theses and Dissertations
The purpose of this study was to describe kinematic changes that occur during an actual marathon. We hypothesized that (1) certain running kinematic measures would change between miles 5 and 25 of a marathon and (2) fast runners would demonstrate smaller changes than slow runners. Subjects (n = 179) were selected according to finish time (Range = 2:20:47 to 5:30:10). Two high-speed cameras were used to measure sagittal-plane kinematics at miles 5 and 25 of the marathon. The dependent variables were stride length, ground time, peak knee flexion during support and swing, and peak hip flexion and extension during swing. …
The Effects Of Indoor Track Curve Radius On Sprint Speed And Ground Reaction Forces, Jesse Tipasa Tukuafu
The Effects Of Indoor Track Curve Radius On Sprint Speed And Ground Reaction Forces, Jesse Tipasa Tukuafu
Theses and Dissertations
Sprinting on a curve is significantly slower than on a straightaway. Although the dimensions vary from track to track, indoor track curves are among the tightest curves that athletes will sprint at maximal speed. Previous studies have provided theories for how speed attenuation occurs when running on a curve. Yet, no previous research has determined how the variability of indoor track curve radii affects trained sprinters at maximal speeds. Purpose: To determine the differences in running speeds, ground time (GT), and medio-lateral (ML) impulse, with different indoor track radii. A secondary purpose was to understand the between-leg differences in GT …
Variations In Running Form Among Female Sprinters, Middle, And Distance Runners, Ruthann Cunningham
Variations In Running Form Among Female Sprinters, Middle, And Distance Runners, Ruthann Cunningham
Theses and Dissertations
In the sport of track and field, runners excel at their events due not only to physiological characteristics but aspects in their form. Characteristics in form help runners achieve the goal in completing their event in the least amount of time possible. For sprinters, this is done by having a shorter swing phase and ground time along with greater power and a longer stride length. Distance runners accomplish the goal of quicker speeds by balancing it with running economy by spending greater time on the ground with shorter stride lengths compared to those in shorter distance running events. Middle distance …

Conclusions from biomechanical data can make a significant difference in the performance of athletes in the hammer throw if properly understood by coaches. By utilizing this scientific approach to the hammer throw event, the throws coach will be able to determine more accurate adjustments and devise training stimuli to better accommodate the athlete. In this case study, we have attempted to bridge the gap between the researcher and the coach in our approach to teaching the hammer throw, by integrating biomechanical analysis. We have employed the use of video analysis as an essential part of our coaching/teaching system. This USATF …
Gender Differences And Biomechanics In The 3000m Steeplechase Water Jump, Kassi R. Andersen, Bryan K. Lindsay, Iain Hunter
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 …
