An Investigation Of Perceived Restrictions On Certified Athletic Trainers Practice, Katy Taake
An Investigation Of Perceived Restrictions On Certified Athletic Trainers Practice, Katy Taake
All-Inclusive List of Electronic Theses and Dissertations
The purpose of this study was to identify the frequency and nature of perceived restrictions by certified athletic trainers (ATCs) and to determine the frequency of perceived restrictions for each practice setting within states that have legislation. This was a qualitative-descriptive study performed with a web-based survey. 10,000 ATCs receiving electronic mail from the National Athletic Trainers' Association (NATA) were invited to participate in this study. 1158 subjects participated in the study, and 724 subjects (295 female and 429 male; age=33.2 ± 8.3yrs) remained after exclusions. A webbased survey was created to evaluate perceived restrictions. Inorder to establish face validity …
Changes In Neuromuscular Function In Collegiate Sprinters During An Indoor Season, Jack W. Skaggs
Changes In Neuromuscular Function In Collegiate Sprinters During An Indoor Season, Jack W. Skaggs
All-Inclusive List of Electronic Theses and Dissertations
Objective: The purpose of this study was to determine the changes in neuromuscular function through the use of the Hoffman Reflex in male Division I collegiate sprinters during an indoor competitive season. Design: a 2 X 4 factorial design. The independent variables in this study were groups (Sprint and Control) and testing times (base, mid, peak and taper). The dependent variable was the soleus Hreflex, anaerobic power, and body composition. Setting: This study took place in the Exercise Physiology Laboratory located in the Health and Human Performance Building at Indiana State University. Subjects: Ten male Division I collegiate sprinters (age: …
Predictive Factors Of Perceived Stress And Work-Related Strain Among Collegiate Athletic Trainers, Shinichiro Sugiura
Predictive Factors Of Perceived Stress And Work-Related Strain Among Collegiate Athletic Trainers, Shinichiro Sugiura
All-Inclusive List of Electronic Theses and Dissertations
Objective: In a college/university setting, certified athletic trainers (ATCs) may have sport coverage, classroom teaching, and clinical instructor responsibilities. The purpose of this study was to determine the most important predictors of perceived stress and work-related strain among ATCs in a college/university setting, how athletic level affected perceived stress and work-related strain, and if the perceived stress score correlated with the work-related strain score. Design and Setting: This study was a webbased survey consisting of demographic and job responsibility questionnaire, the Perceived Stress Scale (PSS), and the Work-Related Strain Inventory (WRSI). To evaluate predictors of perceived stress and work-related strain, …
The Response Of The Hoffmann Reflex To Endurance Training In Male Cross-Country Runners, Randall J. Bergman
The Response Of The Hoffmann Reflex To Endurance Training In Male Cross-Country Runners, Randall J. Bergman
All-Inclusive List of Electronic Theses and Dissertations
Motoneuron pool excitability as measured by the Hoffinann reflex (H-reflex) in endurance-trained subjects has been shown to differ from their untrained counterparts. Further, the effects of endurance training on the H-reflex are equivocal. Objective: To determine if differences exist in the motoneuron pool excitability of the soleus in highly trained endurance athletes due to the effect of endurance training. Design: A 2 X 3 factorial design with repeated measures. Setting: This study took place in the Exercise Physiology Laboratory located in the Health and Human Performance Building on the Indiana State University campus. Subjects: Eleven male cross-country team members (XC; …
The Reliability Of Emg Normalization Procedures For Three Muscles Invol Ved In Knee Extension, Gerrik J. Schepel
The Reliability Of Emg Normalization Procedures For Three Muscles Invol Ved In Knee Extension, Gerrik J. Schepel
Masters Theses
This retrospective study analyzed the three muscles involved in knee extension: vastus medialis, rectus femoris, and vastus lateralis. lt was conducted to determine the reliability of normalization procedures when evaluating the EMG response detected from a muscle. During a maximal voluntary isometric contraction {MVIC), the EMG response of the muscle was recorded and the iEMG moment per unit area was determined. The iEMG response ofthe quadriceps muscles during dynamic exercise was normalized using the MVIC. Subjects (N = 44) performed two consecutive MVICs with a 2-min rest between trials at 110°, 90°, 70°, 50°, and 30° of knee flexion, …
