Effects Of Wider Step Width On Knee Biomechanics In Obese And Healthy-Weight Participants During Stair Ascent, Derek Scott Yocum
Effects Of Wider Step Width On Knee Biomechanics In Obese And Healthy-Weight Participants During Stair Ascent, Derek Scott Yocum
Masters Theses
An increased likelihood of developing obesity-related knee osteoarthritis may be associated with increased peak internal knee abduction moment. Increases in step width may act to reduce this moment. This study focused on how step width influenced the knee joint during stair ascent by healthy and obese participants. Participants ascended stairs while walking at their preferred speed and under one of two step width conditions – preferred and increased. Obese participants experienced greater mediolateral and vertical ground reaction forces (GRFs), as well as increased peak knee extensor moments and push-off peak internal knee adduction moments. The findings of this study indicate …
Effects Of Synthetic Turf And Shockpads On Impact Attenuation Related Biomechanics During Drop Landing, Hang Qu
Masters Theses
Synthetic turf has been widely utilized in sports since 1964. Discrepancies, however, in injury incidence on synthetic turf and natural grass have been reported throughout studies. Adding a shock pad under synthetic turf carpet is claimed to aid in energy absorption and decrease impact loading. Although some studies have conducted materials tests and compared mechanical characteristics of synthetic turf with different shock pads, no studies have examined biomechanical characteristics of impact related human movements on an infilled synthetic turf system with different underlying shock pads. The purpose of this research was to investigate effects of an infilled synthetic turf with …
Mechanisms Of Slowed Foot Tap Speed In Older Adults, Erica L. Hartman
Mechanisms Of Slowed Foot Tap Speed In Older Adults, Erica L. Hartman
Masters Theses
Rapid repetitive tapping, like the Foot Tap Test (FTT), slows with age, but the underlying mechanisms are unknown. Purpose: 1. Test the hypotheses that greater performance variability, increased muscle coactivation, and slowed muscle contractile speeds are related to lower foot tap count (FTC) in older adults; 2. Examine the relationship between FTC and physical function in older adults, using the advanced SPPB-A. Methods: 18 (25.0±3.1years, 9F, mean±SD), and 28 (73.4±4.9, 14F) adults were recruited; the later were divided into Higher (HFO) and Lower (LFO) Functioning based on SPPB-A score. Participants performed 10s of rapid tapping (FTT) while seated. A MATLAB …
Associations Among Perceived Motor Competence, Motor Competence, Physical Activity, And Health-Related Physical Fitness Of Children Ages 10-15 Years Old., Emily Marie Post
Associations Among Perceived Motor Competence, Motor Competence, Physical Activity, And Health-Related Physical Fitness Of Children Ages 10-15 Years Old., Emily Marie Post
Masters Theses
Purpose: To examine the associations among perceived motor competence (PMC), motor competence (MC), physical activity, and health-related physical fitness during middle childhood and early adolescence. Method: Participants were 47, 10-15 year old youth. Each participant completed two visits in East Tennessee or northwest Ohio. During these visits, the participants completed the Bruininks-Oseretsky Test (BOT-2) Analysis Test for Motor Proficiency, Harter’s PMC questionnaire, and the FITNESSGRAM battery for health-related physical fitness. The Actigraph GT3X+ accelerometer was used to measure physical activity. Results: There were significant associations among health-related physical fitness and both motor percentile (rs = 0.44, p < 0.01) and PMC (r …
Factors Lnfluencing Weight Gain And Perceived Barriers Of Exercise In First Semester College Students, Noah C. Neuenfeldt
Factors Lnfluencing Weight Gain And Perceived Barriers Of Exercise In First Semester College Students, Noah C. Neuenfeldt
Masters Theses
College students believe that university weight management interventions impact their health habits. This suggests that universities can play a large role in encouraging students to be active. The purpose of this study was to investigate this claim and to acquire a better understanding of weight change in first year college students in the first semester. We specifically sought to identify the variables that influence weight gain, as well as determine the awareness and usage of resources available to the students. A survey was given to first year students addressing the variables of interest including change in weight and Body Mass …
Maximal Strength Effects Of Cross Education Training On The Elbow Flexors, Molly Dyer
Maximal Strength Effects Of Cross Education Training On The Elbow Flexors, Molly Dyer
Masters Theses
The purpose of this study was to compare the absolute and relative changes in maximal bilateral elbow flexion strength increase after a four-week intervention protocol between a unilateral and bilateral resistance training program in college age females.
Methods: Five non-athlete females, with a mean age of 21.6 years, completed the study. Eligible subjects were randomly assigned to one of two groups; unilateral elbow flexion resistance training (n=2) or bilateral elbow flexion resistance training (n=3). Both groups completed a four-week resistance training three days per week using three sets of ten repetitions at 65% of their predicted one repetition maximum. Maximal …
The Effects Of High Intensity Interval Training On Body-Esteem Among College-Aged Women, Chelsea K. Duncan
The Effects Of High Intensity Interval Training On Body-Esteem Among College-Aged Women, Chelsea K. Duncan
Masters Theses
The purpose of this study was to examine the effects of high intensity interval training (HIIT) on body-esteem among college-aged females. The study had four participants complete a pre-intervention questionnaire, which included BMI information and the Body-Esteem Scale (BES: Franzoi & Shields, 1984). The participants then completed 12 sessions of HIIT, three sessions each week for four weeks. After completing the HIIT protocol, participants filled out a post-intervention questionnaire, including BMI and the BES. The post-intervention questionnaires were then compared to the participants' pre-intervention questionnaires using a paired-samples t test with SPSS software. Small changes in BES scores occurred, however …
