The Efficacy Of Caffeine Supplementation In Collegiate Tennis Players And The Magnitude Of Improvement In Tennis Skill Mediated By Caffeine Influenced By A Polymorphism Of The Cyp1a2 Gene, Courtney Klein
Masters Theses, 2010-2019
Purpose: This study examined the efficacy of caffeine supplementation on tennis performance in male and female collegiate tennis players and whether a polymorphism of the CYP1A2 gene influenced the ergogenic response to caffeine. Methods: Eighteen collegiate tennis players (9 male; 9 female) completed two separate trials. Each test occurred one hour after the administration of either 6 mg/kg of caffeine or a placebo, administered in double-blind fashion. The treadmill portion was comprised of 15 minutes at a velocity corresponding with 50% VO2max followed by 30 minutes of intermittent sprints (5 seconds at 80% VO2max, 15 seconds at 50% VO2max). 90 …
The Independent And Combined Effects Of Carbohydrate And Caffeine Ingestion On Cycling Performance, Tiffany L. Acker
The Independent And Combined Effects Of Carbohydrate And Caffeine Ingestion On Cycling Performance, Tiffany L. Acker
Masters Theses, 2010-2019
Purpose: The purpose of this study was to determine the independent and combined effects of carbohydrate and caffeine ingestion on performance and physiological parameters during high-intensity aerobic cycling (~60 minutes). Methods: Ten cyclists (28 ± 3 yr, 73.2 ± 1.9 kg) performed 20 minutes of steady-state cycling (60% Wmax) followed by a simulated 20-km time trial (TT) under the following four treatment conditions: placebo (PLA), carbohydrate (CHO), caffeine (CAF), and a combination of CHO and CAF (CHO-CAF). One hour prior to exercise subjects ingested a placebo/caffeine capsule. Beverages (250 ml) were consumed immediately prior to the 20-min steady-state, immediately prior …
The Relationship Between Blood Iron Markers, Nutritional Intakes And Bone Mineral Density, Leah Dawn Morrison
The Relationship Between Blood Iron Markers, Nutritional Intakes And Bone Mineral Density, Leah Dawn Morrison
Masters Theses, 2010-2019
PURPOSE: The purpose of this study was to examine the relationship between serum ferritin (sFer) levels, nutrient intake of iron, calcium and vitamin D and bone mineral density (BMD) in female collegiate athletes. It was hypothesized that if an individual had low sFer (20µg/L. An independent T-test also showed no mean differences in BMD levels at any site when the group was divided into high and low sFer levels. CONCLUSION: There was no correlation between sFer level and BMD or between BMD and intake levels of iron, calcium or vitamin D, in female collegiate athletes participating in weight bearing sports. …
Effect Of Deep Oscillation Therapy On The Reduction Of Swelling And Pain Following Acute Ankle Sprain, Lisa Marie Friesen
Effect Of Deep Oscillation Therapy On The Reduction Of Swelling And Pain Following Acute Ankle Sprain, Lisa Marie Friesen
Masters Theses, 2010-2019
Context: Deep oscillation therapy is a novel form of therapy that claims to reduce the amount of pain and swelling in acute orthopedic injuries. However, these claims are based on anecdotal evidence and there have not been any published studies on the efficacy of deep oscillation therapy in reduction of pain and swelling. Due to the prevalence of ankle sprains in physically active individuals, this study compared the effect of deep oscillation therapy in reduction of pain and swelling to conventional treatment. Objective: To compare the effect of deep oscillation therapy on pain and swelling resulting from acute ankle sprains …
Effects Of Strengthening Exercises On Forward Shoulder Posture In Division In Competitive Female Swimmers, Rachel Lynn Ondek
Effects Of Strengthening Exercises On Forward Shoulder Posture In Division In Competitive Female Swimmers, Rachel Lynn Ondek
Masters Theses, 2010-2019
Abstract Forward shoulder posture in the repetitive overhead athlete has been isolated as a possible predisposition for injury. Shoulder strengthening and stretching programs have displayed benefits for overhead athletes such as swimmers to decrease risk of impingement, labral issues, and other shoulder pathology. The purpose of this study was to investigate the effects of strengthening exercises on forward shoulder posture in female overhead athletes. Thirty-one Division I female collegiate competitive swimmers were divided into 3 groups: control, strengthening, and combination of stretching and strengthening. The two intervention groups were assigned a 16 session strength-only or a combined strength and stretching …
Altered Carbohydrate And Protein Content In Sports Beverages: Influence On Recovery From Heavy Endurance Exercise, Christopher Boop
Altered Carbohydrate And Protein Content In Sports Beverages: Influence On Recovery From Heavy Endurance Exercise, Christopher Boop
Masters Theses, 2010-2019
Purpose: The purpose of this study was to compare the efficacy of different carbohydrate-protein recovery beverages following heavy endurance exercise. Methods: Twelve well-trained male cyclists completed a glycogen-depleting trial followed by a 4 hour recovery period before completing a simulated 20-km time trial. During the recovery period, subjects consumed one of three isocaloric beverages [high-carbohydrate/low-protein (HCLP); low-carbohydrate/high-protein (LCHP); carbohydrate (CHO)] at 0h and 2h, as well as immediately following the 20-km time trial. Creatine kinase (CK), muscle soreness, isometric peak torque (MVC), and mental/physical fatigue/energy ratings were measured pre- and post trial. Glucose and lactate were measured during the glycogen …
Influence Of Genotype Variations On Markers Of Skeletal Muscle Recovery From Heavy Endurance Exercise, And On Responses To Carbohydrate-Protein Supplementation, Qingnian Goh
Masters Theses, 2010-2019
Purpose: This study examined the influence of genotype polymorphisms (specifically ACTN3 R577X, IGF-II C13790C, IGF-II G17200A, IGF2AS A1364C, IGF2AS G11711T) on markers of skeletal muscle recovery following an acute bout of heavy endurance exercise, and assessed their role in determining individual responses to carbohydrate-protein supplementation. Methods: Twelve trained male cyclists completed repeated cycling trials, each consisting of an initial session of glycogen-depleting exercise, followed four hours later by a >1 hr time-trial on a computerized cycle ergometer (VeloTron, Racermate, Inc). Subjects were randomly administered a high-carbohydrate low-protein (HCLP), or carbohydrate-only (CHO) beverage, which was consumed immediately and 2-hours post glycogen …
