The Study Of A Generalized Fitness Education Program's Effect On Personality Traits, Garrett Schliep
Theses/Capstones/Creative Projects
This longitudinal study was to measure the influence of a generalized fitness education program on the percentile of individuals’ personality traits in college aged individuals. The personality traits are those determined in the Five Factor Model of Personality. The Five Factor Model of Personality is a beneficial tool used in exercise psychology that refers to a broad domain of personality traits often referred to as the “Big Five”. The findings reject the hypothesis that a fitness education program would shift an individual’s personality a statistically significant amount.

New Perspectives On Foot Segment Forces And Joint Kinetics - Integrating Plantar Shear Stresses And Pressures With Multi-Segment Foot Modeling, Dustin A. Bruening, Spencer R. Petersen, Sarah T. Ridge
Faculty Publications
The role of the foot in gait is not well understood, in part due to challenges in capturing and utilizing segmental ground reaction forces. The purposes of this study were to 1) develop methodology to integrate plantar pressure/shear stresses with a multi-segment foot model, and 2) generate and display key normative data from this combined system. Twenty-six young healthy adults walked barefoot (1.3 m/s) across a pressure/shear sensor with markers matching a published 4-segment kinetic foot model. A novel anatomical/geometric masking method was developed that successfully separated regions aligned with model segmentation. This template-based method can be automated and customized …

Assessment Of Muscular Anatomical And Physiological Development During Injury Rehabilitation, Nicholas Andrews, Petey Mumford, Lauren Tighe
2023 Student Academic Showcase
After an injury occurs, there are many physiological regressions that occur. These regressions lead to altered muscle thickness, muscle length, strength and power potentials, motor recruitment, and neuromuscular control. These variables are further exacerbated if the given injury requires surgical intervention. Rehabilitation aids in reducing these regressions and is important both pre-surgery and post-surgery when intervention beyond rehabilitation is needed. Ultrasound imaging can be utilized to monitor the progression of a muscle's specific muscles anatomy. The muscles of interest are dependent upon the injury, The purpose of this study is to monitor short-term muscular adaptations to establish their importance in …

University of Massachusetts Amherst
Stretch Activation During Fatigue Improves Relative Force Production In Fast-Contracting Mouse Skeletal Muscle Fibers, Philip C. Woods
Masters Theses
Stretch activation (FSA) is the delayed increase in fiber specific tension (force per cross-sectional area) following a rapid stretch and can improve muscle performance during repetitive cyclical contractions. Historically considered minimal in skeletal muscle, our recent work showed the ratio ofstretch- to calcium-activated specific tension (FSA/F0) increased from 10 to 40% with greater inorganic phosphate (Pi) levels in soleus muscle fibers (Straight et al., 2019). Given Pi increases with muscle fatigue, we hypothesize that FSA helps maintain force generation during fatigue. To test this, FSA, induced by a stretch of 0.5% …

Walking Easier By Attaching A Spring-Mass To The Body: A Preliminary Simulation, Hiva Razavi, Philippe Malcolm
UNO Student Research and Creative Activity Fair
When carrying or pushing a load, more force is needed to accelerate and decelerate the additional mass, increasing Ground Reaction Force (GRF). However, this can be reduced by synchronizing the object's movement with the individual's Center of Mass (COM) using antiphase acceleration and deceleration. Past studies have shown this can decrease muscle work and metabolic costs. This study aimed to determine optimal spring parameters to minimize horizontal GRF (GRFh) when pushing a cart by connecting the human to the cart with a spring and damper system.
Three walking conditions were simulated in MATLAB: 1) Normal walking; 2) Walking with a …
