A Comparison Of Anthropometric And Maximal Strength Measures In Rugby Union Players, Thomas Gamazo
A Comparison Of Anthropometric And Maximal Strength Measures In Rugby Union Players, Thomas Gamazo
HIM 1990-2015
To examine differences in body composition and maximal strength between collegiate (CLG) and men's club (CLB) rugby union players, as well as between the forward (FW) and back (BK) positions, seventeen resistance-trained men (24 ± 2.4 yrs; range: 20 ± 27 yrs; 179.3 ± 5.4 cm; 93.7 ± 12.9kg) from a collegiate rugby team (n=11) and a local men's rugby club (n=6) were recruited to participate in the present investigation. Prior to strength testing, height (± 0.1 cm), body mass (± 0.1 kg), and body composition via dual energy x-ray absorptiometry were assessed to determine total percent body fat (%FAT), …
Athletic Trainers' Knowledge And Perceptions Of Testicular Cancer And Testicular Cancer Prevention Practices, Christopher Mings
Athletic Trainers' Knowledge And Perceptions Of Testicular Cancer And Testicular Cancer Prevention Practices, Christopher Mings
HIM 1990-2015
Context: Collegiate male athletes have a higher risk of testicular cancer due to their age group, an increased risk of testicular contusions, and a lack of secondary prevention education. As the athletic training profession increases emphasis on evidence-based practice, it is important for athletic trainers to understand testicular cancer and testicular-self examination as it is outlined within their scope of practice. A general understanding of testicular cancer and the prevention techniques will be important for athletic trainers to promote awareness and health behavior practices. Objective: To examine the athletic trainers' actual knowledge, concern, perceived responsibility, training, feeling of embarrassment, and …
Effect Of Acute L-Alanyl-L-Glutamine (Sustamine) And Electrolyte Ingestion On Plasma Electrolytes, Physiologic Measures, And Neuromuscular Fatigue During Endurance Exercise, William Mccormack
Electronic Theses and Dissertations
The purpose of this study was to compare the efficacy of two dose levels of L-Alanyl-LGlutamine in a commercially available sports drink to the sports drink only on time to exhaustion, neuromuscular fatigue and physiological measures during prolonged endurance exercise. Twelve endurance-trained males (23.5±3.7 yrs; 175.5±5.4 cm; 70.7±7.6 kg) performed four trials, each consisting of 1 hr treadmill runs at 75% of VO2peak followed by a run to exhaustion at 90% of VO2peak. The trials differed in type of hydration. One trial consisted of no hydration (NHY), another required ingestion of only a sports drink (ET), and two trials required …
Effect Of Acute L-Alanyl-L-Glutamine (Sustamine) And Electrolyte Ingestion On Cognitive Function, Multiple Object Tracking And Reaction Time Following Prolonged Exercise, Gabriel Pruna
Electronic Theses and Dissertations
Changes in physiological function occurring during a body water deficit may result in significant decrements in performance, cognitive function and fine motor control during exercise. This may be due to the magnitude of the body water deficit. Rehydration strategies are important to prevent these deleterious effects in performance. The purpose of this study was to examine the changes before and after prolonged exercise of an alanine-glutamine dipeptide (AG) on cognitive function and reaction time. Twelve male endurance-trained runners (age: 23.5 [plus or minus] 3.7 y; height: 175.5 [plus or minus] 5.4 cm; weight: 70.7 [plus or minus] 7.6 kg) participated …
The Cross Education Of Neuromuscular Economy, Kyle Beyer
The Cross Education Of Neuromuscular Economy, Kyle Beyer
Electronic Theses and Dissertations
Cross education is the phenomenon by which the untrained limb will experience a gain in strength following a unilateral resistance training program. However, little is known as to the underlying adaptation occurring in the untrained limb. Purpose: To examine the effect of dynamic unilateral resistance training on the strength and neuromuscular adaptations of both the trained and untrained legs. Methods: Eight previously untrained males (22.38±2.92 y, 1.73±0.08 m, 75.26±14.53 kg) completed a four-week unilateral resistance training program, while another eight untrained males (24.00±4.57 y, 1.84±0.05 m, 94.21±16.14 kg) served as controls. Isometric leg extension strength, leg press 1 repetition maximum …
The Effect Of Moderate Altitude On High Intensity Running Performance During A Game With Collegiate Female Soccer Players, Jonathan Bohner
The Effect Of Moderate Altitude On High Intensity Running Performance During A Game With Collegiate Female Soccer Players, Jonathan Bohner
Electronic Theses and Dissertations
Competition often requires teams that reside at sea level to compete against opponents whose residence is at a moderate altitude. This may pose a potential competitive disadvantage considering that moderate altitude may cause decrements in VO2max, distance covered, and time to exhaustion in endurance athletes. The purpose of this study was to examine the effect of altitude on game performance measures. Six NCAA Division I female soccer players (20.33 ± 1.21 y; 168 ± 6.45 cm; 62.5 ± 6.03 kg) were retrospectively examined. Comparisons were made between two competitions that were played at sea level (SL) within two weeks of …

Endocrine And Contralateral Muscle Responses To Short-Term Unilateral Resistance Training, Carleigh Boone
Electronic Theses and Dissertations
PURPOSE: The purpose of this study was to examine the effects of short-term lower body unilateral resistance training on hormonal, muscle morphological, and performance measures in young men. METHODS: Seventeen healthy, untrained young men (Age: 22.8 ± 3.7 y; BMI: 26.5 ± 4.9 kg/m2) were randomly assigned to one of two groups (UT: 22.9 ± 4.6 y, 25.3 ± 4.2 kg/m2; CON: 24.0 ± 4.6 y, 27.7 ± 5.1 kg/m2). Resistance training consisted of 4 weeks of unilateral lower body and bilateral upper body exercises on 3 days per week. Each training session entailed unilateral countermovement jumps (3 × 8), …
The Effects Of High-Intensity Interval Training And 28 Days Of [Beta]-Hydroxy-[Beta]-Methybutyrate Supplementation On Measures Of Aerobic Power And Metabolic Thresholds, Edward Robinson
Electronic Theses and Dissertations
Purpose: To examine the effects of 28 days of β-hydroxy-β-methylbutyrate free acid (HMB) and high-intensity interval training (HIIT) on maximal oxygen consumption (VO2peak), ventilatory threshold (VT), respiratory compensation point (RCP) and time to exhaustion (Tmax) in collegeaged men and women. Methods: Healthy men and women (n=34, age and VO2peak= 22.7+3.1yr and 39.3+5.0 mL. kg-1.min-1, respectively) participated in this study. All participants completed a series of tests prior and subsequent to treatment. A maximal oxygen consumption test was performed on a cycle ergometer to assess VO2peak, Tmax, VT, and RCP. The peak power output (Ppeak), power at VT (PVT) and power …
