An Ecological Momentary Assessment Of Self-Improved And Self-Evaluation Body Comparisons: Associations With College Women's Body Dissatisfaction And Exercise, Rachel I. Macintyre, Kristin E. Heron, Abby L. Braitman, Danielle Arigo

Psychology Faculty Publications

Upward body comparisons are prevalent among college women and associated with body dissatisfaction and disordered eating. However, less is known about distinguishing features of the comparisons themselves as they occur in daily life. The primary purpose of the present study was to examine whether two types of upward body comparisons previously studied experimentally (self-improvement and self-evaluation) are differentially associated with body- and exercise-related outcomes in real-life settings using ecological momentary assessment (EMA). Undergraduate women (N = 74) between 18-25 years (Mage = 20.4, SD = 1.63) completed five surveys on smartphones daily for seven days. EMA measures …

The Independence Effects Of Gravitational And Inertial Forces On Gait Transitions In Humans, Nathan Frakes

Cal Poly Humboldt theses and projects

The Dynamic Similarity hypothesis suggests gravitational and inertial forces plays a role in determining preferred transition speed (PTS) for walk to run transitions (WRT) and run to walk transitions (RWT), and that humans prefer to transition gait when the ratio of inertial force (IF) to gravitational force (GF) (i.e. Froude #) is ~0.5. Purpose: To investigate the effect of gravitational and inertial forces on PTS, Froude # (Fr) and kinematics for both WRT and RWT. Methods: Twelve healthy adults (9 M, 3 F) performed WRT and RWT trials on a treadmill across seven combinations of altered body weight (BW) and …

Anaerobic Capacity Measures In Healthy Active Adults Ages 18-29: Normative Reference Values And Differences Between Sex, Dylan E. Roberts

Cal Poly Humboldt theses and projects

The purpose of this study was to develop normative reference values for the modified Anaerobic Speed Test (mAST), an anaerobic capacity test that can be administered and completed on a commercial treadmill.

Fall Reading Week: Exploring The Effects On Student Well-Being, Roobina Medhizadah

Theses and Dissertations (Comprehensive)

Mental health is a concerning issue in post-secondary institutions across Ontario. Post-secondary students are challenged with many stressors such as time management and living independently for the first time (Wagner & Rhee, 2013). In an attempt to help students, maintain or improve their mental health, universities across Ontario have implemented fall reading week, a mid-semester break (Poole et al., 2017). Previous studies (Cramer & Pschibul, 2017; Poole et al., 2017) provided mixed results in whether fall reading week positively influences student mental health and well-being. To date, few studies have explored the influence of fall reading week on student health …

Spinal Motor Neuron Excitability And Balance Control Changes Following Downslope Walking, Nikki Aitcheson-Huehn

Theses and Dissertations (Comprehensive)

Downslope walking (DSW) has been proposed as a rehabilitation tool for people with Multiple Sclerosis (PwMS) although there are mixed findings in young adults (YA) regarding the balance control changes, despite both populations experiencing depressed spinal motor neuron (MN) pool excitability. Our aim was to determine whether YAs could demonstrate improved balance control in conjunction with SOL H reflex depression (estimate of spinal MN excitability) following DSW. We also aimed to determine whether reciprocal inhibition was a potential mechanism for H reflex depression via conditioned SOL H reflexes. Thirty young adults (23±1.4y, 6 males) were assigned to 30-minutes of DSW …

Neuromechanical Tuning For Arm Motor Control, Russell Lee Hardesty Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

Movement is a fundamental behavior that allows us to interact with the external world. Its importance to human health is most evident when it becomes impaired due to disease or injury. Physical and occupational rehabilitation remains the most common treatment for these types of disorders. Although therapeutic interventions may improve motor function, residual deficits are common for many pathologies, such as stroke. The development of novel therapeutics is dependent upon a better understanding of the underlying mechanisms that govern movement. Movement of the human body adheres to the principles of classic Newtonian mechanics. However, due to the inherent complexity of …
