Motor Performance And Motor Unit Behavior In Response To Ischemic Conditioning Post Stroke, Saad Alqahtani

Dissertations (1934 -)

The purpose of this dissertation was to quantify changes in motor performance and motor unit behavior in response to ischemic conditioning (IC) post stroke. People with stroke often have long term functional deficits following therapeutic interventions characterized by underlying muscle weakness and fatigability. IC is an emerging therapy which involves transient bouts of ischemia to a limb with some evidence that IC may help improve motor function post stroke. Although the mechanisms of IC are likely multifactorial, the premise for this dissertation is that IC increases sympathetic drive and the excitability of the nervous system resulting in enhanced activation of …

Clinical Determinants Of Vo2 Max Response To Endurance Training: Heritage Family Study, Emanuel Ayala

Theses and Dissertations

Background: Maximal oxygen uptake trainability (U+0394VO₂max) is largely determined by non-modifiable traits. However, less is known of the contribution of modifiable phenotypes to VO₂max response to endurance training. The purpose of this study was to examine the relationship between baseline cardiopulmonary, metabolic, and body composition traits and U+0394VO₂max.

Methods: Subjects were 717 healthy, physically inactive adults (44% female, 34% Black) who completed a 20-week, highly standardized, endurance training program as part of the HERITAGE Family Study. Resting and exercise phenotypes were collected at baseline and post-training. A total of 33 variables related to cardiopulmonary, …

Coordination Variability And Injury Risk In Experienced Collegiate Dancers, Emily Klinkman

All NMU Master's Theses

Dance is a sport that places a number of physical demands upon the human body, and injuries are a common occurrence in the sport. While it has not yet been linked to dance-related injury, coordination variability (CV) is a measure of how much movement strategy changes between repetitions of a task and low levels of CV have been linked to injury in other sports. This study aimed to determine the relationship between CV and dance injury in collegiate dancers. Eight (8) undergraduate student subjects were recruited from the dance major and minor, BFA major and minor, and recreational dancers who …

Do Infants Avoid A Traversable Slope Leading Into Deep Water?, Carolina Burnay, Chris Button, Rita Cordovil, David Anderson, James Croft

Research outputs 2014 to 2021

Ramps used to access swimming pools are designed with a shallow slope that affords easy access for all including infants. Locomotor experience has been linked to infants’ avoidance of falling into the water from drop-offs; however, the effect of such experience on infants’ behavior when a slope is offered to access the water has not been addressed. Forty-three crawling infants (M_age = 10.63 ± 1.91 months; M_crawling = 2.38 ± 1.77 months) and 34 walking infants (M_age = 14.90 ± 2.18 months; M_walking = 2.59 ± 1.56 months) were tested on a new Water …

Faculty Publications

Background

Excessive screen time (≥ 2 h per day) is associated with childhood overweight and obesity, physical inactivity, increased sedentary time, unfavorable dietary behaviors, and disrupted sleep. Previous reviews suggest intervening on screen time is associated with reductions in screen time and improvements in other obesogenic behaviors. However, it is unclear what study characteristics and behavior change techniques are potential mechanisms underlying the effectiveness of behavioral interventions. The purpose of this meta-analysis was to identify the behavior change techniques and study characteristics associated with effectiveness in behavioral interventions to reduce children’s (0–18 years) screen time.

Do Water Safety Lessons Improve Water Safety Knowledge?, Michael J. Tipton, Joseph Muller, Cristian Abelairas Gomez, Jo Corbett

International Journal of Aquatic Research and Education

A person, usually a child or young adult, dies by drowning every 90 seconds around the planet. Most drowning prevention initiatives do not assess the efficacy of the intervention. In this study, thirteen- to fourteen-year-olds had their level of water safety knowledge (covering cold shock, rips and tides) assessed before, just after, and 3-6 months after one, 25-minute water safety lesson on these topics. We evaluated the knowledge gained and retained on water safety “awareness” (i.e., knowledge of risks) and “confidence” in terms of knowing what to do in an emergency. The results demonstrated that the lesson significantly increased water …

Sympathoinhibition And Vasodilation Contribute To The Acute Hypotensive Response Of The Superoxide Dismutase Mimic, Mntnbuoe-2-Pyp5+, In Hypertensive Animals, Sarah L. Schlichte, Elizabeth J. Pekas, Taylor J. Bruett, Elizabeth A. Kosmacek, Bryan T. Hackfort, Jordan M. Rasmussen, Kaushik P. Patel, Song-Young Park, Rebecca E. Oberley-Deegan, Matthew C. Zimmerman

Health and Kinesiology Faculty Publications

The pathogenesis of hypertension has been linked to excessive levels of reactive oxygen species (ROS), particularly superoxide (O2•−), in multiple tissues and organ systems. Overexpression of superoxide dismutase (SOD) to scavenge O2•− has been shown to decrease blood pressure in hypertensive animals. We have previously shown that MnTnBuOE-2-PyP5+ (BuOE), a manganese porphyrin SOD mimic currently in clinical trials as a normal tissue protector for cancer patients undergoing radiation therapy, can scavenge O2•− and acutely decrease normotensive blood pressures. Herein, we hypothesized that BuOE decreases hypertensive blood pressures. Using angiotensin II (AngII)-hypertensive mice, we demonstrate that BuOE administered both intraperitoneally and …
