The Effects Of A Moisture-Wicking Fabric Shirt On The Physiological Responses During Acute Exercise In The Heat, Kimberly Wigboldy
Masters Theses
The purpose of this study is to investigate the effects that a form fitted, moisture-wicking fabric shirt, promoted to have improved evaporative and ventilation properties, has on the thermoregulatory, physiological and perceptual response during moderate intensity exercise in the heat for an extended duration of exercise of 90 minutes. Ten healthy subjects (7 males, 3 females), completed two heat stress tests consisting of 20 minute seated rest in a neutral environment (24°C, 60% RH), 30 minute seated rest in a hot environment (33°C, 60% RH), and 90 minutes of exercise(50% V02 peak) on a magnetically-braked cycle ergometerin a …

Optimization Problem Formulation For Predicting Knee Muscle And Contact Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, Benjamin J. Fregly, Josep M. Font-Llagunes
Mechanical and Aerospace Engineering Faculty Publications
The human body has more muscles than degrees of freedom (DOF), which leads to indeterminacy in the muscle force calculation. In this study, an optimization problem to estimate the lower-limb muscle forces during a gait cycle of a patient wearing an instrumented knee prosthesis is formulated. It consists of simulating muscle excitations in a physiological way while muscle parameters are calibrated.

Multiple Sclerosis Alters The Mechanical Work Performed On The Body's Center Of Mass During Gait, Shane R. Wurdeman, Jessie M. Huisinga, Mary Filipi, Nikolaos Stergiou
Journal Articles
Patients with multiple sclerosis (MS) have less-coordinated movements of the center of mass resulting in greater mechanical work. The purpose of this study was to quantify the work performed on the body’s center of mass by patients with MS. It was hypothesized that patients with MS would perform greater negative work during initial double support and less positive work in terminal double support. Results revealed that patients with MS perform less negative work in single support and early terminal double support and less positive work in the terminal double support period. However, summed over the entire stance phase, patients with …

Effects Of High-Velocity Versus Low-Velocity Resistance Training On Resting Metabolic Rate And Functional Performance In Older Adults, Laura Ashleigh Morgan
Graduate Theses and Dissertations
The purpose of this study was to compare the effects of a 12-week high-velocity resistance training (HVRT) protocol to a traditional low-velocity resistance training (LVRT) protocol on resting metabolic rate (RMR) and other selected measures of muscular and functional fitness in older adults. Nineteen adults between the ages of 65 and 82 participated: 8 HVRT, 7 LVRT, and 4 controls (CTRL). Initially, no differences existed between groups except for age (p = .016). HVRT (75.6 years) was older than LVRT (69.6 years) and CTRL (69.3 years). The exercise intervention consisted of 2 days/week sessions for 12 weeks at 3 sets …

International Journal of Exercise Science
International Journal of Exercise Science 6(3) : 242-249, 2013. Fatigue is a common neuromuscular factor examined in relation to risk of ACL injury. Unfortunately, variations between the protocols used to induce fatigue in studies examining this phenomenon may have contributed to reported inconsistencies in the effects of fatigue on movements with high-risk of ACL injury. In addition, the ecological validity of fatigue experienced as a result of protocols commonly administered in the experimental setting is unclear. The purpose of this study was to examine the ecological validity, using basketball competition as the criterion measure, of two fatigue protocols commonly used …

International Journal of Exercise Science 6(3) : 230-235, 2013. Pedometers are simple inexpensive tools that are widely used for the measurement of physical activity. Reactivity is always a concern when using pedometers. An issue not yet addressed is the role previous knowledge has on the impact of reactivity. The primary purpose of this study was to examine if reactivity exists in 4th-6th grade students and if prior knowledge about pedometers had an effect on reactivity. Participants included 109 (54 females) 4th- 6th grade students from a suburban charter school. Prior to data collection, students …

International Journal of Exercise Science
International Journal of Exercise Science 6(3) : 199-207, 2013. Paintball is a popular recreational sport played by 3.655 million Americans and may be sufficient physical activity to promote health. Paintball has been played as an organized sport since the 1980’s and is essentially a game of tag, except instead of touching an opponent by hand opponents are tagged by shooting them with a paintball that leaves a mark indicating who has been eliminated. A previous evaluation of paintball as physical activity had 13 subjects undergo a VO2max test to develop a heart rate (HR) /oxygen consumption relationship, and …

International Journal of Exercise Science 6(3) : 188-198, 2013. This study evaluated the validity of the current U.S. Department of Defense (DOD) circumference-based prediction equation for males to detect body composition changes in comparison to air-displacement plethysmography (ADP). Body composition was assessed using ADP and the DOD equation at the beginning and end of an academic school year among 21 male (18-29 years-old) Army ROTC cadets. Body mass significantly increased (+1.8 Kg) after 9 months. Significant method by time interactions for percent body fat (percent body fat), fat mass (FM), and fat-free mass were found (p = 0.022, p …

Plasma Lactate Accumulation During Running With Body Weight Unloading By Lbpp, Nicole Nevitt Rasmussen
Theses and Dissertations
At any given running speed, weight support with a lower body positive pressure (LBPP) device (i.e. Alter-G treadmill) reduces V̇O2. However, it is unknown how application of LBPP during running impacts lactate metabolism, specifically lactate threshold. Purpose: To determine if body weight unloading with the Alter-G treadmill alters lactate threshold. Methods. Maximal aerobic capacity (V̇O2max) and lactate threshold (LT) was determined in 8 male subjects on an Alter-G treadmill at 100% and 80% body weight loading at 0% grade in a randomized crossover design. V̇O2max tests started at 7 mile h-1 and increase speed by 1 mile h-1 every 2 …
