Post-Activation Potentiation Following Maximal Effort, Multi-Joint, Isokinetic Eccentric Contractions, Tom Dickey
All Graduate Reports and Creative Projects, Fall 2023 to Present
Post-activation potentiation (PAP) is a phenomenon that can enhance muscle performance following maximal or near-maximal muscle contractions. While the effects of concentric and isometric conditioning contractions on PAP have been studied, less is known about the influence of eccentric muscle actions. This study investigated the effects of a multi-joint eccentric overload (EOL) protocol on PAP expressed through countermovement jump (CMJ) height and isokinetic peak force (PF) outcome measures. Twenty-eight recreationally trained participants (18-30 years) completed three visits in a randomized, counterbalanced design. Following familiarization, participants performed either an EOL protocol involving 2 sets of 6 maximal isokinetic eccentric contractions or …

Soil Reclamation Strategies In Construction Disturbed Soil, Alexis Koelling
All Graduate Reports and Creative Projects, Fall 2023 to Present
The rapid urbanization occurring in arid environments like the Intermountain West region of the U.S. significantly alters soil conditions. Construction of roads, buildings, and other infrastructure leads to the disturbance of soil structure, nutrient depletion, and reduced fertility. This research addresses the need for sustainable soil management practices that may restore soil health post-construction. In this study, the effectiveness of various soil amendments and application methods on specific soil parameters and turfgrass establishment in construction-disturbed soils was evaluated. The study highlights the critical role of soil amendments, particularly municipal solid waste (MSW) compost, in improving soil quality and plant growth. …
Effects Of Blood Flow Restriction During Acute Multi-Joint Eccentric Exercise On Muscle Recovery, Cody Fisher
Effects Of Blood Flow Restriction During Acute Multi-Joint Eccentric Exercise On Muscle Recovery, Cody Fisher
All Graduate Reports and Creative Projects, Fall 2023 to Present
Blood flow restriction (BFR) exercise has become an increasingly common modality due to evidence that it may yield positive muscle-related effects from low-intensity exercise. However, eccentric-only exercise in a multi-joint format has not yet been investigated in regard to the BFR influence on muscle recovery characteristics. The purpose of this study was to assess muscle recovery responses via isometric peak force (PF), soreness (i.e., VAS, PPT, PPD), and functional power (i.e., SLHD) following a 5-minute low-load multi-joint eccentric exercise bout with or without blood flow restriction. Thirty participants were randomly assigned into either an eccentric-only (CON) or an eccentric BFR …
Asymmetries In Ncaa Division I Tennis Players Compared To An Athletic Control Group, Elizabeth Cafferty
Asymmetries In Ncaa Division I Tennis Players Compared To An Athletic Control Group, Elizabeth Cafferty
All Graduate Reports and Creative Projects, Fall 2023 to Present
Limb asymmetries are an expected adaptation to years of training for athletes participating in dominant-sided sports. Previous research on this topic lacks an athletic control group. PURPOSE: To determine the magnitude of upper limb asymmetries in dominant-sided athletes (tennis players) compared to nondominant-sided athletes (cross-country runners). METHODS: Male and female NCAA Division I athletes (10 tennis, 11 cross-country) participated. Dual-energy x-ray absorptiometry (DXA) was used to measure bone mineral content (BMC), bone mineral density (BMD), and lean mass (LM) of the whole body, upper extremities, and forearms. Circumference measurements were taken at mid-biceps and the widest part of the forearms. …
