Lee Weidauer

Objectives: The purpose of this study was to determine the effect of sports participation on cortical bone in the tibia. Methods: 53 female collegiate athletes (25 cross-country, 16 soccer, and 12 volleyball) and 20 inactive controls had the left distal 20% tibia scanned by pQCT. Cortical volumetric BMD (vBMD) was measured within the cortical shell at the anterior, posterior, medial, and lateral regions and standard deviations were calculated. Results: Total vBMD was greater in the control group (1161±5 mg/mm3) than each of the sports (p<0.05). Soccer players (1147±5 mg/mm3) had greater vBMD than volleyball players (1136±7 mg/mm3) (p<0.05), but similar to cross-country runners (1145±5 mg/mm3). Cortical thickness was greatest in soccer players (4.1±0.1 mm), while cross-country and control subjects (3.8±0.1 mm) had greater thickness than volleyball players (3.4±0.1 mm)(p<0.05). Periosteal circumference was greater in volleyball players (71±1.4 mm) than soccer, cross-country, and control subjects (68±0.9, 69±0.8, and 66±1 mm, respectively; all, p<0.05). vBMD variation within the cortical shell was greater among control subjects (70±6 mg/cm3) than each of the athlete groups, with soccer players having lower variation than cross country runners (within-in person SD 36±6 mg/cm3 and 54±5 mg/cm3 respectively; p<0.05). Conclusion: These results indicate bone geometry and distribution within the cortical shell of ...

Estimating Variations In Metabolic Cost Within The Stride Cycle During Level And Uphill Walking, Arash Mohammadzadeh Gonabadi

Student Research and Creative Activity Fair

Indirect calorimetry provides the average cost of a stride cycle and prevents from identifying which part of the gait cycle causes increased metabolic cost in patients, however, recent simulation methods allow estimating the time profile of metabolic cost within the stride cycle. In this study, we compare the estimations of the time profile of the metabolic cost of two simulation methods for level and uphill walking. We used kinematic, kinetic and electromyography data from level and uphill walking (one participant) to estimate the time profiles of metabolic cost using the muscle-level metabolic model of Umberger using electromyography and kinematic data ...

University of Nebraska at Omaha, School of Health and Kinesiology, Omaha, NE

BACKGROUND: Mitochondria are highly concentrated in skeletal muscle tissue, and undergo damage from ROS during metabolic processes. This damage is often left unrepaired and leads to mitochondrial dysfunction, which has been linked to many common diseases. Exercise training increases mitochondrial development within skeletal muscle tissue and thus may be protective. Environmental temperature, when paired with exercise may provide an even greater effect than exercise alone. PURPOSE: The purpose of this study is to analyze the effects of three weeks of exercise training ...

The Energy Paradox Of The Ankle-Foot Complex During Human Walking, Nikolaos Papachatzis, Kota Takahashi

Student Research and Creative Activity Fair

Flexor hallucis longus (FHL) is a multiarticular muscle that possesses the potential to alter foot’s functional and mechanical behavior, since it performs multiple significant functions during walking (e.g supports the medial longitudinal arch of the foot).The purpose of this study was to determine if the functional changes of the FHL are associated with the foot’s adaptations to the mechanical demands of walking. Backward walking is an experimental method capable of altering how the forces propagate underneath the foot and disrupting the mechanical function of the FHL muscle. We hypothesized that: (1) the muscle activity of the ...
