Force Characteristics In Different Shoe Designs, Bryson Nakamura Jan 2011

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 …


The Acute Effect Of Pre-Exercise Static And Dynamic Stretching Of The Leg Flexors, Jocelyn Riordan Jan 2011

The Acute Effect Of Pre-Exercise Static And Dynamic Stretching Of The Leg Flexors, Jocelyn Riordan

Summer Research

The purpose of this study was to investigate the acute effects of pre-exercise static and dynamic stretching on peak torque of the knee extensors in female athletes and non-athletes. Thirty subjects (15 athletes and 15 non-athletes) completed three tests on an isokinetic dynamometer. After performing a randomly assigned pre-exercise stretching protocol (no stretching, static or dynamic) the subjects performed eight maximal, reciprocal knee extensions on an isokinetic dynamometer at three speeds (180, 120, 60˚/s) while measuring peak torque. No significant differences (p < .05) were found among the three stretching protocols for either the athletes or non-athletes. However, the results suggest that static stretching may cause a loss in overall peak torque in contrast to dynamic stretching in athletes.


The Relationship Between Dynamic Balance And Isokinetic Ankle Strength In Female College Athletes, Nika Evans Jan 2011

The Relationship Between Dynamic Balance And Isokinetic Ankle Strength In Female College Athletes, Nika Evans

Summer Research

Conflicting results have been found between dynamic balance and isokinetic ankle strength. PURPOSE: To investigate the relationships between ankle strength and dynamic balance. METHOD: 15 healthy female Division III varsity athletes (INSERT DEMOGRAPHIC DATA) were tested on a Cybex NORM isokinetic dynamometer performing maximal ankle plantar and dorsiflexion. Dynamic balance was assessed using the SEBT. Isokinetic strength was assessed through 8 maximal contractions of plantar and dorsiflexion at 60, 120, and 180º/s with a 60 second rest period between each velocity set. Pearson’s correlations were used to assess the relationship between the dynamic balance score and peak torque at each …


Identification Of Flock House Virus Cell Surface Receptor Protein(S) Using Affinity Chromatography And Chemical Cross-Linking, Kristen Delwiche Jan 2011

Identification Of Flock House Virus Cell Surface Receptor Protein(S) Using Affinity Chromatography And Chemical Cross-Linking, Kristen Delwiche

Summer Research

The mechanism for non-enveloped virus host-cell penetration remains poorly understood. Flock House Virus (FHV), a small insect virus that infects Drosophila melanogaster cells in tissue culture, is an excellent model system for studying how non-enveloped viruses enter and infect cells. There is a wealth of high-resolution structural information available, and it is simple, consisting only of two single-stranded RNA genome segments surrounded by an icosahedral protein capsid. In this study, chemical-cross-linking and affinity chromatography were used to search for candidate receptor proteins for FHV. Several candidate proteins were identified, but the results remain inconclusive and additional research is required to …


Anticipatory Testosterone Response To Competition In Female Collegiate Endurance Athletes, Becca Adams Jan 2011

Anticipatory Testosterone Response To Competition In Female Collegiate Endurance Athletes, Becca Adams

Summer Research

High blood testosterone has been linked to the expression of aggressive personalities, but few studies have investigated the relationship between testosterone and competitiveness in anticipation of athletic competition. The purpose of this study was to examine the relationship between self-reported competitiveness and the anticipatory pre-competition circulating testosterone level. Twelve college-aged female athletes participated in a track relay-style race. Blood serum testosterone was tested 24 hours prior and 15 minutes prior to a competition using chemiluminescent immunoassay. Subjects completed the Revised Competitiveness Index (RCI) upon finishing the race. A dependent t-test was used to calculate differences between the two serum samples. …


Effect Of Shoe Design And Gender On Valgus Angle, Mandy Warner Jan 2011

Effect Of Shoe Design And Gender On Valgus Angle, Mandy Warner

Summer Research

The purpose of this study was to determine the difference between genders in body position during jumping movements while wearing shoes with varying midsoles. Twenty-two apparently healthy female and seven males voluntarily participated in this study. Subjects were current or recently graduated NCAA division III athletes of weight bearing sports and familiar with plyometric jumping. Subjects performed plyometric jumps from three box heights (46 cm, 30.5 cm and 21.6 cm) while being filmed from both the front and side view. Each jump was completed wearing four different pairs of shoes. The subject was represented as digitized points designed to capture …
