The Effect Of Acute Caffeine Withdrawal On Exercise Performance In Habitual Caffeine Users, Timothy D. Griest
The Effect Of Acute Caffeine Withdrawal On Exercise Performance In Habitual Caffeine Users, Timothy D. Griest
Masters Theses, 2020-current
Purpose: The purpose of this study was to investigate how exercise performance is impacted by acute withdrawal from caffeine (CAF) in habitual users and if CAF ingestion will reverse the negative impact of withdrawal or have a net positive benefit. Methods: Ten recreational cyclists (age 39.1 ± 14.9 y; VO2max 54.2 ± 6.2 mL/kg/min) who were habitual CAF consumers (394 ± 146 mg/d) completed four trials, each consisting of peak isokinetic torque testing and a 10-km time trial (TT). On each trial day, subjects consumed either 1.5 mg/kg CAF to prevent withdrawal or placebo (PLA) 8 hours before their …
The Effect Of Creatine Supplementation On Body Composition And Total Body Water Measured By Multi-Frequency Bioelectrical Impedance, Emily A. Buck
The Effect Of Creatine Supplementation On Body Composition And Total Body Water Measured By Multi-Frequency Bioelectrical Impedance, Emily A. Buck
Masters Theses, 2020-current
Background: Acute fluid ingestion causes an increase in estimated body fat percentage (BF%) measurements by single frequency (SF-BIA) and multi-frequency bioelectrical impedance (MF-BIA). However, it is unknown if MF-BIA accurately measures total body water (TBW) and BF% after chronic fluid retention. Creatine supplementation causes fluid retention, and resultant increases in TBW and body mass. Research is needed to determine if MF-BIA is capable of detecting fluid retention secondary to creatine supplementation. Methods: 13 male and 14 female subjects (18-22 y) completed one week of creatine monohydrate or maltodextrin supplementation at a dose of 0.3 g/kg body weight. Subjects completed pre-supplementation …
The Effect Of Dietary Nitrate Supplementation On Physical And Cognitive Performance During Load Carriage In Military Cadets, Nicholas C. Bordonie
The Effect Of Dietary Nitrate Supplementation On Physical And Cognitive Performance During Load Carriage In Military Cadets, Nicholas C. Bordonie
Masters Theses, 2020-current
Purpose: The purpose of this study was to determine the effects of dietary nitrate supplementation on physical and cognitive performance during exercise conducted under heavy pack load in military cadets. Methods: Ten college-aged males (VO2max 56.2 ± 3.7 ml/kg/min) consumed 140mL/d of concentrated beetroot juice (BRJ; containing 12.8 mmol of dietary nitrate) or a placebo (PL; flavor, color, energy, and texture-matched with no dietary nitrate) for six days preceding an exercise trial. The trial consisted of 45 min of constant-load exercise on a treadmill at 4.83 km/h and 1.5% grade, followed immediately by a 1.6-km time-trial completed at maximal …
Does A Bout Of Acute Resistance Exercise Attenuate The Post-Prandial Lipemic Response To A High Fat Meal In 50-80 Year-Old Adults, Summer Simulcik
Does A Bout Of Acute Resistance Exercise Attenuate The Post-Prandial Lipemic Response To A High Fat Meal In 50-80 Year-Old Adults, Summer Simulcik
Masters Theses, 2020-current
Background: A single high-fat meal (HFM) is known to elevate blood lipid levels above what is normal, resulting in postprandial lipemia (PPL). Chronic hyperlipemia has been associated with increased risk for cardiovascular disease (CVD) and type-2 diabetes mellitus (T2DM) development. Current physical activity (PA) guidelines recommend at least one set of 8-12 repetitions of each exercise to attenuate this risk. Adults older than 50 (OF) years (y) are at an increased risk for cardiometabolic disease compared to younger adults (YA). Aerobic exercise (AE) performed in the pre-prandial period has been observed to attenuate PPL in both OF and YA. However, …
Examining The Effects Of Oral Contraceptive Use On Thermoregulation, Whitley C. Atkins
Examining The Effects Of Oral Contraceptive Use On Thermoregulation, Whitley C. Atkins
Graduate Theses and Dissertations
Purpose: The purpose of this investigation was to evaluate the effects of combined (estradiol and progestin) monophasic oral contraceptive pill (OCP) use on thermoregulation. Further, we sought to evaluate OCP use on acute rehydration post-exercise in the heat using recommended rehydration guidelines. Methods: Twelve healthy, aerobically trained (VO2peak = 47.8 ± 4.7 mL/kg/min), long term female oral contraceptive users completed a familiarization trial and two experimental days separated by ≥ 7 days. The two experimental trials were identical except for the hormone dosing phase. One trial was completed during the third week of active pill dosing (ACT) and one during …
Inflammaging: Inflammatory Biomarkers Associated With Nutrition, Metabolism And Muscle Tissue Oxygenation Relative To Sarcopenic Status In Older Adults, Marni Elise Shoemaker
Inflammaging: Inflammatory Biomarkers Associated With Nutrition, Metabolism And Muscle Tissue Oxygenation Relative To Sarcopenic Status In Older Adults, Marni Elise Shoemaker
Open Access Theses & Dissertations
The purpose of this study is to examine if we can differentiate inflammaging between sarcopenic and non-sarcopenic older adults by exploring if there are differences between biomarkers of inflammation and nutritional status in older adults with distinct differences in skeletal muscle mass, strength, and function, metabolic flexibility, and muscle tissue oxygenation. Twenty-one non-sarcopenic (mean±standard deviation, age = 73.1±6.2 yrs, n=5 males, n=5 females) and sarcopenic (age = 81.2±10.5 yrs, n=6 males, n=5 females) were categorized based on muscle mass and strength criteria according to the European Working Group on Sarcopenia in Older People. Body composition, handgrip and leg extension strength, …
Nutrition Education And The Effects On Athletic Performance In Collegiate Athletes With Low Energy Availability, Karleigh Sudenga
Nutrition Education And The Effects On Athletic Performance In Collegiate Athletes With Low Energy Availability, Karleigh Sudenga
Health and Nutritional Sciences Graduate Students Plan B Capstone Projects
Current research suggests that collegiate athletes lack nutritional knowledge needed for optimal athletic performance. The absence of basic nutritional knowledge in college athletes puts them at an increased risk for RED-S and its sports performance consequences. The objective of this narrative review is to evaluate the literature on low energy availability in collegiate athletes and determine if nutrition education can improve athletic performance. Multiple studies concluded that nutrition education may improve dietary intake in collegiate athletes, while there was one contradicting study that found that athletes improved nutritional knowledge but did not improve dietary intake. 3 studies found that low …
