The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman
The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman
Senior Honors Theses
Osteoarthritis is a prominent and debilitating form of joint disease characterized by pain and deterioration of the articular cartilage and other tissues in the affected joint. Research has identified a variety of risk factors for osteoarthritis, including age, obesity, gender, previous injury, and occupation. The relationship between running and osteoarthritis is a topic of particular interest because of the prevalence of running as a simple and physiologically beneficial form of exercise. Increasing evidence suggests that recreational running has at worst no effect and at best a protective effect on joint and articular cartilage health in contrast to high-intensity professional/elite-level running …

Background: The majority of research on barefoot running focuses on acute changes in altering footwear without regard to the runner's experience with barefoot or minimalist footwear running. Objective: The objective of this study was to compare the effect of footwear (standard cushioned running shoes, barefoot) and running surface (flat surface, uneven terrain) on gait in experienced runners using minimalist shoes. Methods: Terrain running was simulated by three custom-made mats with randomly placed firmly attached stones. Seven experienced trail runners participated in this study. All participants were forefoot strikers. Participants underwent three-dimensional kinematic and kinetic analysis consisting of five running trials …

As recreational running continues to gain popularity, more individuals are seeking ways to improve running performance. RunSmart is a running intervention program designed to enhance a runner’s form. In addition to correcting flaws in a runner’s form, RunSmart offers the opportunity for runners to continue a regular regimen while slowly integrating changes in form. The purpose of this case series was twofold: to determine if the RunSmart program coincides with improvements in oxygen consumption (VO2), a variable often associated with better running performance times, and to evaluate the RunSmart program in regard to enhancing gait biomechanics. Five recreational …
Ambulation Speed And Corresponding Mechanics Are Associated With Changes In Serum Cartilage Oligomeric Matrix Protein, W. Matt Denning, Michael Becker Pardo, Jason G. Winward, Iain Hunter, Sarah T. Ridge, J. Ty Hopkins, C. Shane Reese, Allen C. Parcell, Matthew K. Seeley
Ambulation Speed And Corresponding Mechanics Are Associated With Changes In Serum Cartilage Oligomeric Matrix Protein, W. Matt Denning, Michael Becker Pardo, Jason G. Winward, Iain Hunter, Sarah T. Ridge, J. Ty Hopkins, C. Shane Reese, Allen C. Parcell, Matthew K. Seeley

Because serum cartilage oligomeric matrix protein (COMP) has been used to reflect articular cartilage condition, we aimed to identify walking and running mechanics that are associated with changes in serum COMP. Eighteen subjects (9 male, 9 female; age = 23 ± 2 yrs.; mass = 68.3 ± 9.6 kg; height = 1.70 ± 0.08 m) completed 4000 steps on an instrumented treadmill on three separate days. Each day corresponded to a different ambulation speed: slow (preferred walking speed), medium (+50% of slow), and fast (+100% of slow). Synchronized ground reaction force and video data were collected to evaluate walking mechanics. …
Improving Running Performance Using Non-Running Tasks, Darien Lewis
Improving Running Performance Using Non-Running Tasks, Darien Lewis
Honors College
For decades researchers and runners have endeavored to improve endurance running performance. Recent evidence suggests that adding resistance training to a running program can improve running performance. Our purpose was to determine if 6wks of resistance exercise via negative eccentrically-induced work (RENEW), an exercise that increases muscle size, strength, and stiffness, could serve as an effective “non-running” modality for improving running performance. Recreational runners were assigned to a: RENEW (n=7), plyometric (PLYO, n=7), or control (CON, n=7) group. RENEW trained on an eccentric ergometer (3x/wk, 10-30min, 54-66% of peak heart rate) while the PLYO performed …
Force Characteristics In Different Shoe Designs, Bryson Nakamura
Force Characteristics In Different Shoe Designs, Bryson Nakamura
Summer Research
Women’s shoes are known to be constructed from the same parameters as men’s shoes but on a smaller scale. However, foot and gait characteristics are different between genders The purpose of this study was to determine if mid-sole design has an effect on ground reaction force characteristics during running, cutting and jumping motions. Twenty-two apparently healthy female (73.8±8.4 kg; 1.74±0.06 m) and seven male (73.5±5.3 kg; 1.68±0.02 m) current or recently graduated NCAA Division III athletes voluntarily participated in this study. Subjects wore four shoes with different mid-sole designs while performing five different actions: running, cutting, shuffling, back cut and …

This study evaluated how preparing for an interval workout, while wearing a cooling vest, affects core temperature (Tc), heart rate (HR), and interval time in long-distance runners. Nineteen male collegiate cross-country runners exercised under two different conditions: (a) wearing a Nike PreCool™ ice vest for one hour prior to the workout (30 minutes resting with the vest and 30 minutes while performing their warm-up); and (b) a control condition utilizing a traditional warm-up. Subjects performed 8 x 1000 m intervals. HR and Tc were measured prior to warm-up, immediately before the first interval, and after each interval. Tc measured before …

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