Exploration Of Warm-Up Protocols On Muscular Fatigue, Sahil Kapadia

Honors Undergraduate Theses

Muscular dystrophy is a genetically linked myopathy with no cure available. The lack of a cure makes early detection and treatment of muscular dystrophy imperative. When reviewing protocols examining muscular fatigue at submaximal isometric contractions, proper warm-up appeared to be absent and could have caused skewed results and conclusions. This study examines the effects of implementing a warm-up protocol before fatiguing trials. In this study, 10 adult subjects conducted fatiguing protocols with the right rectus at submaximal isometric contractions. The warm-up period included a light walk along with contractions at 20% and 33% of maximal voluntary isometric contraction (MVIC) levels. …

Aerobic Vs. Anaerobic Exercise: The Role Of Exercise Attitudes, Frequency, And Perception Of Effort In Cognitive And Psychological Benefits, Khalil Dabdoub, Michael Oliver

Science University Research Symposium (SURS)

Exercise has been shown to have numerous benefits. Benefits often depend on the type and duration of exercise. Existing research focuses primarily on long-term aerobic exercise with studies showing 20-30 minutes of exercise to be beneficial. What remains unknown is how little exercise can show benefits. Anaerobic exercise has not been studied much, and when it has, findings have been mixed. Research is needed to elucidate the potential cognitive and psychological benefits of anaerobic exercise of different durations. In addition to exercise type, factors such as one’s attitude towards exercising, exercise frequency, and perception of effort may play a role …

Influence Of Approach Angle On Ball Velocity During The American Football Instep Placekick, Kristoph C. Lopata

Master's Theses and Doctoral Dissertations

High ball velocity in American football placekicking (PK) enhances the opportunity to score during competition. Insight into self-selected (SS) approach angle and whether an optimal angle exists for maximal ball velocity may improve performance. Methods: Three selected approach angles (30°, 45°, 60°) and a SS approach angle were assessed to analyze kicking velocity among 11 intercollegiate male kickers. Descriptive statistics analyzed SS angles, and a one-way repeated measures ANOVA with the significance level set a p < .05 compared maximal ball velocity between angles. Results: Mean SS angle was 37.25° ± 3.67, and the SS and 45° approach produced the highest maximal ball velocities; however, no approach angle (SS, 30°, 45°, 60°) differed significantly F(3, 30) = 1.869, p < .156. Conclusions: Approach angle did not significantly affect maximal ball velocity. However, future studies are needed with larger sample sizes and diverse placekicking populations who are participating in American football.

A Season Long Investigation Of Social Emotional Learning Associated With High School Basketball Participation, Daniel Gould, Eric M. Martin, Lauren F. Walker

Kinesiology Faculty Publications and Presentations

This qualitative, longitudinal investigation had three purposes: (1) to investigate social emotional learning (SEL) outcomes athletes reported from participating in high school basketball; (2) to identify critical incidents that occurred over the course of a season that were associated with SEL outcomes; and, (3) to explore the processes identified as leading to the athletes’ SEL outcomes. High school varsity basketball players (four males, five females) were interviewed five times over the course of their season. Content analysis revealed that major categories of SEL outcomes identified included: psychological dispositions (e.g., accountability, discipline); psychological skills (e.g., emotional regulation, time management); and interpersonal …

The Effects Of Neural And Mechanical Interventions On Muscle Size Versus Function During Short Term Immobilization Of The Lower Limb, Kylie Harmon

Electronic Theses and Dissertations, 2020-2023

Limb immobilization is a commonly used therapeutic intervention during periods of recovery from injury. To improve rehabilitation outcomes, interventions that curtail the severe decrements in muscular size and strength that occur during immobilization are critically needed. The purpose of this study was to assess the effects of two distinct interventions during one week of knee-joint immobilization on muscular size, strength, and neuromuscular function. Thirty-nine healthy, college-aged adults (21 males and 18 females) participated in this study. Participants were randomized into one of four groups: immobilization only (n = 9) , immobilization + action observation/mental imagery (AOMI) (n = 10), immobilization …

Analyse Du Concept De Marge De Manœuvre En Ergonomie Du Point De Vue Du Contrôle De La Motricité Humaine, Philippe Corbeil, André Plamondon, Denys Denis

Rapports de recherche scientifique

Le concept de marge de manœuvre se définit comme la liberté dont dispose un travailleur pour élaborer différentes façons de travailler afin de répondre aux exigences de production, et ce, sans effet défavorable sur sa santé (Coutarel, Caroly, Vézina et Daniellou, 2015; St-Vincent et al., 2011). Une forte charge de travail jumelée à une faible latitude décisionnelle restreint l’élaboration des gestes et pourrait pénaliser ainsi la santé des opérateurs. Les connaissances actuelles des façons de faire des manutentionnaires, qu’ils soient experts ou non, ne nous permettent pas d’apprécier dans sa totalité l’ampleur de cette liberté lorsqu’un individu doit répéter …

Honor Thyself, Alonzo O. Williams

Dance (MFA) Theses

The black male experience and identity in America are filled with complexity. We struggle to know ourselves. We work to see the way of love and the peace of an unviolated free spirit. We want to engage with ourselves with the highest degree of freedom and comfort, not to continue to question our identity in a life-threatening white patriarchal masculinity ideal. Honoring oneself from the lenses of the Reconstruction era of the United States is essential. Reconceptualizing this history explores the significance of emphasizing Reconstruction in my life as a black male to go through a process of self-discovery and …

Velocity Field Measurements Of The California Sea Lion Propulsive Stroke Using Bubble Piv, Gino Perrotta, Frank E. Fish, Danielle S. Adams, Ariel M. Leahy, Abigal M. Downs, Megan C. Leftwich

Biology Faculty Publications

California sea lions are among the most agile of swimming mammals. Most marine mammals swim with their hind appendages-flippers or flukes, depending on the species-whereas sea lions use their foreflippers for propulsion and maneuvering. The sea lion's propulsive stroke generates thrust by forming a jet between the flippers and the body and by dragging a starting vortex along the suction side of the flipper. Prior experiments using robotic flippers have shown these mechanisms to be possible, but no flow measurements around live sea lions previously existed with which to compare. In this study, the flow structures around swimming sea lions …

Effects Of Post-Exercise Recovery Drink Composition On Subsequent Performance In Masters Class Athletes, Erica Goldstein

Electronic Theses and Dissertations, 2020-2023

Carbohydrate (CHO) and carbohydrate-protein coingestion (CHO-P) have been shown to be equally effective for enhancing glycogen resynthesis and subsequent same-day performance when CHO intake is suboptimal (≤0.8 g/kg). Few studies have specifically examined the effect of isocaloric CHO vs CHO-P consumption on subsequent high-intensity aerobic performance with limited time to recover (≤2 hours) in masters class endurance athletes. Participants (n = 22) were assigned to consume one of three beverages during a 2-hour recovery period: PLA (electrolytes and water), CHO (1.2 g/kg bm), or CHO-P (0.8 g/kg bm CHO + 0.4 g/kg bm PRO). All beverages were standardized to one …

MV: There were statistically significant main effects present for both condition (p = 0.002; g = 0.10-0.23) and load (p < 0.001; g = 0.95-3.93). However, the condition x time interaction effect was not statistically significant (p = 0.259). • PV: There were statistically significant main effects present for both condition (p = 0.016; g = 0.11-0.23) and load (p < 0.001; g = 0.42-1.6), but there was no statistically significant condition x time interaction effect (p = 0.101). • Post hoc analysis indicated that there was a significant difference between MV (p = 0.006) and PV (p = 0.032) between the traditional and 100% AEL conditions. • Moderate effect sizes were found with MV between the traditional and 100% AEL conditions at both 70% CON (g = 0.55) and 80% CON (g = 0.70). • No practically significant differences were found for PV.

Evaluation Of Air Consumption And Work Efficiency In Structural Firefighters, Emily Lynn Langford

Theses and Dissertations--Kinesiology and Health Promotion

INTRODUCTION: For safe and efficient fireground performance, firefighters (FF) must consume air supplied by the self-contained breathing apparatus (SCBA) efficiently while sustaining high work rates. Firefighter research and fire department physical ability assessments typically quantify performance solely on task completion time (i.e., work rate), failing to consider the critical element of air consumption efficiency, which subsequently impacts the SCBA’s functional work duration. PURPOSES: (Arm 1, Aim #1) To examine variability in air consumption (AC) between FF during standardized pace tasks; (Arm 1, Aim #2) To evaluate AC efficiency (ACE) against a recognized metabolic-work rate concept of economy; (Arm …
