An Electromyography Study Of Muscular Endurance During The Posterior Shoulder Endurance Test, Neil A. Evans, Emily Dressler, Timothy L. Uhl

Physical Therapy Faculty Publications

The primary purpose was to determine if there is a difference between the median frequency slopes of 5 posterior shoulder muscles during the initial portion of the Posterior Shoulder Endurance Test (PSET) at the 90° and 135° shoulder abduction positions. Fifty-five healthy volunteers (31 females) participated. The median frequency of the posterior deltoid (PD), upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and infraspinatus (INF) was measured during the PSET at 90° and 135° of shoulder abduction. External torque of 13 ± 1 Nm was used for females and 21 ± 1 Nm for males. A fixed effect multi-variable …

An Investigation Into Fatigue Management: Effects Of Two Different Loading Protocols On Markers Of Inflammation And The Endocrine Response, Jake Bernards

Electronic Theses and Dissertations

The purposes of this dissertation were to 1) determine the effectiveness of the neutrophillymphocyte ratio (NLR) as an athlete monitoring tool in resistance training and 2) determine if repetition maximum or relative intensity loading scheme is superior in managing fatigue through the hormonal, inflammatory, and performances response throughout a 10-week periodized resistance training program. Results from the dissertation give merit to continued research regarding the use of NLR as a monitoring tool to help determine the degree of recovery. Furthermore, results from this dissertation lead to questioning the effectiveness of using a repetition maximum (RM) loading scheme within a periodized …

Mood State Changes Accompanying The Crossfitopen™ Competition In Healthy Adults, Allyson G. Box, Yuri Feito, Steven J. Petruzzello, Gerald T. Mangine

Faculty and Research Publications

Background: Specific mood states were examined during the CrossFit Open, a consecutive 5-week fitness competition involving five separate CrossFit®workouts, to determine whether the unique design or strenuous workouts of the competition resulted in acute and/or chronic mood statealterations. Methods: Participants (n= 8) completed the Profile of Mood States (POMS) questionnaire one-week prior to the competition (baseline), prior to (PRE), immediately post (IP), 30-min post-(30P) and 60-min post-workout (60P) each week. Tension, depression, anger, confusion, fatigue and vigor were derived from the POMS, as was Total Mood Disturbance (TMD) and an Energy Index (EI). Results: Workout intensity exceeded 93% HRmaxeach week. …

The Acute Effects Of A Multi-Ingredient Pre-Workout Supplement On Resting Energy Expenditure And Exercise Performance In Recreationally Active Females, Michael Cameron, Clayton L. Camic, Scott Doberstein, Jacob L. Erickson, Andrew R. Jagim

Faculty Scholarship

Background

The use of dietary supplements to improve performance is becoming increasingly popular among athletes and fitness enthusiasts. Unfortunately, there is a tremendous lack of research being done regarding female athletes and the use of sport supplements. The purpose of this study was to examine the acute effects of multi-ingredient pre-workout supplement (MIPS) ingestion on resting metabolism and exercise performance in recreationally-active females.

Methods

Fifteen recreationally-active females participated in a randomized, double-blind, placebo controlled study. Subjects completed baseline, and two experimental testing sessions in a cross-over design fashion. Experimental testing included assessment of resting energy expenditure (REE), heart rate, and …
