An Examination Of Finish Time Variation For Collegiate Cross Country National Championships By Gender, Kevin Riley Peters

Boise State University Theses and Dissertations

In cross country, women compete over shorter distances than men with little justification for these differences. The purpose of this study was to assess gender differences for the spread of finishing times and examine the appropriateness of shorter competition distances for females. Forty-six cross country national championship data sets (n_males = 10,788; n_females = 10,884) from the NCAA (1999-2011) and NAIA (2005-2011) were utilized for analyses. Several measures of variation were computed to assess spread of finishing times data (i.e., Coefficient of Variation [CV]; Interpercentile Ranges [IR], and Rates of Separation [RS; IR divided by the distance …

Changes In In Vivo Knee Contact Forces Through Gait Modification, Allison Kinney, Thor F. Besier, Amy Slider, Scott L. Delp, Darryl D. D'Lima, Benjamin J. Fregly

Mechanical and Aerospace Engineering Faculty Publications

Gait modification represents a non-invasive method for reducing knee joint loading in patients with knee osteoarthritis. Previous studies have shown that a variety of gait modifications are effective in reducing the external knee adduction moment. The external knee adduction moment is often used as a surrogate measure of medial compartment force. However, a recent study showed that reductions in the external knee adduction moment do not guarantee reductions in medial compartment loads. Therefore, direct measurement of changes in knee contact force is important for determining the effectiveness of gait modifications. A previous study found that medial thrust gait and walking …

Throwing Frame For Athletes With Dissabilities, Andrew Higgins, Stefan Owechko, Gabriel (Gabe) Terrasas, Kevin Crisfield

Mechanical Engineering

Team Zeus’ senior project was to design, build and test a working throwing frame system for Bridge II Sports, a nonprofit organization in North Carolina. The throwing frame is used to allow athletes and individuals with disabilities to throw shot-put, discus, and javelin using a frame to sit against. Team Zeus was specifically tasked to build a frame that is lighter weight and more transportable than products that are currently on the market. This frame also is adjustable to accommodate a wide range of athlete weights, sizes, and abilities. The final result is a 35lb aluminum frame with two different …

Effectiveness Of Group Kickboxing As A Means To Improve Gait And Balance In Individuals With Ms, Kurt Jackson, Kimberly Edginton Bigelow, Christina Cooper, Harold L. Merriman

Mechanical and Aerospace Engineering Faculty Publications

In recent years, there has been a particular emphasis on identifying and delivering appropriate therapeutic interventions that address the significant balance and gait impairments that affect individuals with multiple sclerosis (MS). Group interventions implemented in community settings have been especially of interest, including tai chi classes. Recently, the authors conducted a preliminary study to examine whether group kick-boxing, which requires more vigorous movements, might be a feasible intervention. Initial findings showed promise and led the authors to pursue a more rigorous follow-up study, with the objective of determining whether a 5-week group kickboxing class improved clinical measures of balance and …

Muscle Contributions To Frontal And Transverse Plane Whole-Body Angular Momentum, Richard R. Neptune, Craig P. Mcgowan, Allison Kinney

Mechanical and Aerospace Engineering Faculty Publications

The purpose of this study was to build upon previous work by analyzing how gravity and individual muscles contribute to frontal and traverse plane whole-body angular momentum. Identifying which muscles are responsible for generating angular momentum has important implications for the diagnosis and treatment of movement disorders.

The Decline In Baseball Participation Amongst African American Youth, Michael Mudrick

Master's Theses

@font-face { font-family: "Cambria"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0in 0in 10pt; font-size: 12pt; font-family: "Times New Roman"; }div.Section1 { page: Section1; }

The basis for this thesis was to study the decline in baseball participation amongst African American youth through the lens of social learning theory. This was done in conjunction with interviews with 10 young African American non-baseball players, ages 11-13, who resided in an urban setting in a northeastern city. Because of the paucity of African Americans in Major League Baseball today, social learning theory, a philosophy heavily predicated on the influence of role models, was seen …

The Effects Of Sodium Bicarbonate Supplementation On Lower-Body Hypertrophy-Type Resistance Exercise, Benjamin Mclean Carr

Dissertations

A number of studies have demonstrated the ergogenic effects of induced-alkalosis on high-intensity intermittent exercise performance. Purpose: The aim of the present study was to examine the effects of sodium bicarbonate (NaHCO₃) administration on a high-volume hypertrophy-type resistance exercise regimen for the lower body. Methods: In a double-blind counterbalanced manner, 12 resistance-trained male participants (mean ± SD; age = 20.3 ± 2 yr, mass = 88.3 ± 13.2 kg, height = 1.80 ± 0.07 m), with a minimum of two years of training experience, ingested either 0.3 g˙kg^-1 of NaHCO₃ or calcium carbonate (CaCO₃) …

Pre-Swing Deficits In Forward Propulsion, Swing Initiation And Power Generation By Individual Muscles In Hemiparetic Walking, Carrie L. Peterson, Allison Kinney, Steven A. Kautz, Richard R. Neptune

Mechanical and Aerospace Engineering Faculty Publications

Clinical studies of hemiparetic walking have shown pre-swing abnormalities in the paretic leg suggesting that paretic muscle contributions to important biomechanical walking subtasks are different than those of non-disabled individuals. Three-dimensional forward dynamics simulations of two representative hemiparetic subjects with different levels of walking function classified by self-selected walking speed (i.e., limited community=0.4–0.8 m/s and community walkers=>0.8 m/s) and a speed-matched control were generated to quantify individual muscle contributions to forward propulsion, swing initiation and power generation during the pre-swing phase (i.e., double support phase proceeding toe-off). Simulation analyses identified decreased paretic soleus and gastrocnemius contributions to forward propulsion …

Relationships Between Muscle Contributions To Walking Subtasks And Functional Walking Status In Persons With Post-Stroke Hemiparesis, Allison Kinney, Carrie L. Peterson, Steven A. Kautz, Richard R. Neptune

Mechanical and Aerospace Engineering Faculty Publications

Walking speed is commonly used to predict stroke severity and assess functional walking status (i.e., household, limited community and community walking status) post-stroke. The underlying mechanisms that limit walking speed (and functional walking status by extension) need to be understood to improve post-stroke rehabilitation. Previous experimental studies have shown correlations between paretic plantarflexor output during the pre-swing phase and walking speed and suggest that the paretic hip flexors can compensate in some hemiparetic subjects. Modeling and simulation studies of healthy walking have shown that the ankle plantarflexors, soleus (SOL) and gastrocnemius (GAS), and uniarticular hip flexors (IL) are essential contributors …

Differences In Aerobic Response To Wheelchair Locomotion, David Pomfret

Master's Theses

The purpose of this study was to explore the differences in the aerobic response to wheeling between wheelchair dependent individuals and able-bodied individuals of similar genders and ages. Five wheelchair dependent men (WC) and five able-bodied men (AB) performed a 13 minute wheeling test (5 min. at rest, 8 min. wheeling) at 4.0 km∙hr-1. Heart rate (HR) and VO2 were recorded using a Vmax ST system during the constant speed test. There was no significant difference in HR or VO2 between the two groups during rest. Both HR and VO2 were higher for WC during exercise. The mean METS during …

Electromyographic Analysis Of Trunk Muscle Activation During A Throwing Pattern Following Rotator Cuff Mobilization, Aubrey L. Doede

CMC Senior Theses

Correct muscular activation of the body segments during an overhand throw is achieved when movement originates in the larger and more proximal legs and trunk and moves sequentially to the smaller, distal segments of the shoulder and arm. This sequence permits angular velocity to transfer progressively through the throw as part of an open kinetic chain. The athlete can summate angular velocity and segmental forces only if he is able to create a separation between the body segments during the movement pattern, and this separation is thus essential to effective segmental sequencing for activation of the trunk muscles to occur …
