A Survey-Based Study Of The Changes To Self-Efficacy, Trust In Coaching, Goal Orientation, And State Anxiety That Occur During A Marathon Training Taper, Erica A. Witoslawski

Senior Honors Projects, 2010-2019

Throughout a sport season, athletes’ physiological systems are constantly broken down and strengthened due to repeated practices and competitions. However, not just the physiological benefits of tapering impact performance. The purpose of this study was to extend the current literature that has found connections between self-efficacy, trust in coaching, state anxiety, goal orientation, and sport performance by assessing these variables during a marathon training taper period. The study analyzed included 29 subjects who were enrolled in a general-education health and fitness course focusing on marathon training through a series of surveys electronically administered 3 times (baseline, pre-taper, and post-taper) throughout …

Relationship Between Breakfast And Basketball Shooting Accuracy, Dimitrije Cabarkapa

Masters Theses, 2010-2019

Purpose: The purpose of this study was to determine if collegiate and recreational basketball players shooting accuracy improved after consumption of breakfast (BF) compared to no-breakfast (No-BF).

Methods: 24 male and female collegiate and recreational basketball players completed a three-week intervention study with a crossover design. Subjects were randomly assigned to a four-day BF or No-BF treatment starting on Monday and completed testing that included a free-throw drill and timed 2-point and 3-point drills on day four. Treatment switched the following Monday. Food intake records were collected during each treatment phase.

Results: There was no difference between BF and No-BF …

Physiological Differences In Cardiovascular Hemodynamics Across Treadmill And Cycle Exercise As Assessed Through Impedance Cardiography, Daniel S. Valcicak

Masters Theses, 2010-2019

Impedance cardiography (IC) measures cardiovascular hemodynamics non-invasively during exercise. However, IC measurements assessing physiological differences across treadmill (TM) and cycle (CYC) exercise has not been investigated. The purpose of this study is to investigate whether hemodynamic measurements assessed via IC are consistent between TM and CYC exercise at two absolute exercise intensities. Twenty-one men (age = 21.4 ± 0.5 y; BMI = 24.4 ± 0.5) completed four exercise tests, two TM and two CYC. Within each test, two, five-minute, steady-state stages were completed with targeted intensities of 5 (MODex) and 7 (VIGex) metabolic equivalents (METs). Oxygen consumption (VO₂) …

Caffeine Intake Helps Maintain 3-Km Cycling Performance The Morning Following Sleep Restriction, Erin E. Horil

Masters Theses, 2010-2019

Abstract

Introduction: Although a full understanding of the role of sleep is debated, it is widely accepted that sleep is important for recovery from heavy exercise. Recent research suggests that sleep restriction (SR) may negatively impact recovery and subsequent performance. It is unknown if caffeine supplementation mitigates this performance decrement. Our objective was to investigate the effect of caffeine supplementation on exercise performance following one night of SR in trained cyclists.

Methods: Subjects (n=10) completed a 3-km time trial (TT) and an exhaustive bout of exercise in the evening (EX1), then returned to repeat the TT the following …

Exploring Rehabilitation Adherence And The Motivational Climate Created By Athletic Trainers: A Mixed Methods Approach, Kaleb W. Cusack

Masters Theses, 2010-2019

The purpose of the study was to explore the relationship between the athletic trainer created motivational climate and rehabilitation adherence displayed by their athletes. Four certified athletic trainers from one National Collegiate Athletic Association Division I institution participated. The study implemented a convergent mixed methods design, using the Rehabilitation Adherence Measure for Athletic Training as a quantitative measure of adherence and a semi-structured interview to establish the strategies athletic trainers use to organize the rehabilitation process, provide feedback to athletes, and evaluate rehabilitation progress. The semi-structured interview also allowed for other emerging themes during analysis. Results indicated that high-adhering athletes …

The Effect Of Menstrual Phase And Oral Contraceptive Steroids On Caffeine During Cycling Performance, Annette M. Lemanski

Masters Theses, 2010-2019

PURPOSE: There is evidence that female sex hormones impact caffeine metabolism, with decreased CYP1A2 activity and diminished caffeine clearance in women with higher estrogen levels. Therefore, the objectives of this project were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. METHODS: Sixteen recreationally trained female cyclists, oral contraceptive steroid (OCS) users (n=8, age = 21.4 ± 1.4 years, height = 168.4 ± 3.6 cm, weight = 63.6 ± 7.2kg, VO_2max = 48.0 ± 4.0 ml/kg/min), and non-users (n=8, age = 20.9 ± 2.1 years, height = 161.0 ± …

Early Versus Delayed Rehabilitation After Arthroscopic Rotator Cuff Repair, Abigail Chang, Jessica Dennis

Physician Assistant Capstones, 2016 to 2019

Objective: To determine how the timing of rehabilitation, early versus delayed, affects clinical results and tendon healing rates after arthroscopic rotator cuff repair. Design: Systematic literature review. Methods: Searches were done in PubMed, utilizing the terms arthroscopic rotator cuff repair, rehabilitation, early, and delayed. In PubMed the following filters and terms were used: published in the last 10 years, humans, randomized controlled trial, free full-text articles, and English. Results: The Keener et al study was included because it evaluated clinical results and tendon healing rates after arthroscopic repair using two distinct rehabilitation protocols, early versus delayed …

The Effects Of Coffee Ingestion On The Acute Testosterone Response To Exercise, Taylor Landry

Masters Theses, 2010-2019

Abstract

This study investigated the effects of coffee ingestion (COF) on serum testosterone responses to exercise in recreationally weight-trained males. Subjects ingested either 12 ounces of 6mg/kg caffeinated coffee (COF), decaffeinated coffee (DEC), or water (PLA) one hour prior to exercise in a randomized, within-subject, crossover design. The exercise session consisted of 21 minutes of high intensity interval cycling (alternating intensities corresponding to two minutes at power outputs associated with 2.0 mmol/L lactate and 4.0 mmol/L lactate) followed by resistance exercise (7 exercises, 3 sets of 10 repetitions, 65% 1RM, 1-minute rest periods). Subjects also completed repetitions to fatigue tests …
