Gardiner, Nigel Spry, Dennis R. Taaffe, David Joseph, M Akhlil Hamid, Peter Chong, David Hughes, Kyra Hamilton, Daniel A. Galvão

Research outputs 2014 to 2021

Background: Despite being a critical survivorship care issue, there is a clear gap in current knowledge of the optimal treatment of sexual dysfunction in men with prostate cancer. There is sound theoretical rationale and emerging evidence that exercise may be an innovative therapy to counteract sexual dysfunction in men with prostate cancer. Furthermore, despite the multidimensional aetiology of sexual dysfunction, there is a paucity of research investigating the efficacy of integrated treatment models. Therefore, the purpose of this study is to: 1) examine the efficacy of exercise as a therapy to aid in the management of sexual dysfunction in men …

Self-Regulating Smoking And Snacking Through Physical Activity., Hwajung Oh, Adrian H. Taylor

Peninsula Medical School

OBJECTIVE: Emotional snacking contributes to weight gain after smoking cessation. Exercise acutely reduces cravings for cigarettes and snack food. This study examined if different exercise intensities acutely reduces snack and cigarette cravings and attentional bias (AB) to video clips of snacks and cigarettes among abstinent smokers. METHODS: Abstinent smokers (and snackers; N = 23) randomly did 15 mins of moderate and vigorous cycling and a passive control in a cross-over design. Visual initial AB (IAB) and maintained AB (MAB) were assessed pre- and after treatment while watching paired snacking/neutral or smoking/neutral video clips.

Racial Differences In Self-Efficacy Expectations For Exercise, Selena P. Smith

Honors Theses

This project examined the link between race and self-efficacy. Self-efficacy pertains to an individual’s confidence in ability to complete or engage in a particular task or activity (Bandura, 1986). Prior research shows that self-efficacy has a great influence on exercise initiation and adherence (Bandura, 1986; Dishman, 1982; Rodgers and Sullivan, 2001). Research also supports that Caucasians are more likely to participate in exercise than African Americans (Centers for Disease Control and Prevention, 2000).

Participants included 51 females, 31 Caucasians and 20 African Americans, between the ages of 18 and 50 years old. The women were recruited from local fitness gyms, …

Oral Branched-Chain Amino Acid Supplements That Reduce Brain Serotonin During Exercise In Rats Also Lower Brain Catecholamines, Sujean Choi, Briana Disilvio, Madelyn H. Fernstrom, John D. Fernstrom

Biomedical Sciences Faculty Research and Publications

Exercise raises brain serotonin release and is postulated to cause fatigue in athletes; ingestion of branched-chain amino acids (BCAA), by competitively inhibiting tryptophan transport into brain, lowers brain tryptophan uptake and serotonin synthesis and release in rats, and reputedly in humans prevents exercise-induced increases in serotonin and fatigue. This latter effect in humans is disputed. But BCAA also competitively inhibit tyrosine uptake into brain, and thus catecholamine synthesis and release. Since increasing brain catecholamines enhances physical performance, BCAA ingestion could lower catecholamines, reduce performance and thus negate any serotonin-linked benefit. We therefore examined in rats whether BCAA would reduce both …

Using Behavioral Incentives To Promote Exercise Compliance In Women With Cocaine Dependence, Leila Islam

Theses and Dissertations

To date, low rates of patient compliance have made it impractical to study whether regular exercise can contribute to positive outcomes in women with substance use disorders (SUD). One robust strategy for promoting and maintaining behavior change is contingency management (CM). CM has been used successfully to reinforce drug abstinence, treatment attendance, and other pro-social behaviors. CM delivers incentives (prizes) contingent upon target behaviors, though can be expensive. To reduce costs, CM is often delivered with an escalating variable-ratio schedule, first tested by Petry and colleagues (2005). As a Stage Ib behavioral therapies development project (Rounsaville et al., 2001), the …

Resistance Training In Untrained Individuals: Impact Of Light Repetition Ranges On Improvements In Fat Free Mass, Courtenay D. Lewis

Doctoral Dissertations

The hypertrophy range (8-12 repetitions at 70-85% one-repetition maximum (1RM)) has long been considered the optimal resistance training protocol for the development of fat-free mass (FFM). Recent investigations have hypothesized that lighter repetition zones (over 12 repetitions and less than 67% 1RM) are as effective as heavier loads for the development of FFM. The purpose of this investigation was to determine whether local muscular endurance workouts could sustain and further increase FFM following a program emphasizing the hypertrophy zone. Methods: Healthy, untrained subjects (36 men and 27 women, ages 23 ± 3) completed 96 resistance training workouts. After baseline …

Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman

Electronic Theses and Dissertations

Weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year (U.S. Department of Health and Human Services, 2010). Obese adults have an increased risk for serious health conditions including high blood pressure and cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and certain cancers (National Cancer Institute, 2012). Participation in exercise can help control weight, strengthen muscles and bones, and reduce the incidence of cardiac events, stroke, hypertension, type 2 diabetes, colon and breast cancers, osteoporotic fractures, gallbladder disease, obesity, depression, anxiety, and delay mortality …

Genetic Determinants Of Habitual Physical Activity And Overweight And Obesity, Harold Lee

Master's Theses

We tested 6 single nucleotide polymorphisms (SNPs) associated with obesity from genome wide association studies for their association with physical activity (PA). Healthy European-American women (n=265) and men (n=230) (23.5±0.3yr, 24.6±0.2kg•m^-2) were genotyped for MC4R (rs17782313), FTO (rs9939609), TMEM18 (rs6548238), NEGR1 (rs2815752), SH2B1 (rs7498665), and KCTD15 (rs11084753), and completed the Paffenbarger PA Questionnaire. We examined gene interactions by summing the number of obesity effect alleles. RESULTS: Normal weight subjects with MC4R T expended 1981.2±741.7kcal∙wk^-1 less than non-carriers in total PA (p=0.008), 1825.9±650.2 kcal∙wk^-1 less in sports/recreation (p=0.027), and 1231.3±552.7 kcal∙wk^-1 less …

Voluntary Exercise Protects Against Methamphetamine-Induced Oxidative Stress In Brain Microvasculature And Disruption Of The Blood--Brain Barrier, Michal Toborek, Melissa J. Seelbach, Cetewayo S. Rashid, Ibolya E. András, Lei Chen, Minseon Park, Karyn A. Esser

Physiology Faculty Publications

BACKGROUND: There is no effective therapeutic intervention developed targeting cerebrovascular toxicity of drugs of abuse, including methamphetamine (METH). We hypothesize that exercise protects against METH-induced disruption of the blood--brain barrier (BBB) by enhancing the antioxidant capacity of cerebral microvessels and modulating caveolae-associated signaling. Mice were subjected to voluntary wheel running for 5 weeks resembling the voluntary pattern of human exercise, followed by injection with METH (10 mg/kg). The frequency, duration, and intensity of each running session were monitored for each mouse via a direct data link to a computer and the running data are analyzed by Clock labTM Analysis software. …

Female Division I Cross Country Runners: Is Balance An Issue?, Stephanie Taylor

Honors Theses

Injuries, including those resulting from falls, are virtually unavoidable in the sport of cross country. Due to the constantly changing terrains that cross country runners face, falls and injuries may be a more common aspect of the sport than previously thought. The strenuous nature of the sport and increased injury risk faced by runners are things that make being successful very difficult. Researchers have made connections between joint stability, muscle fatigue, proprioception, and muscle strength and injury/fall rate. Studies have found that balance abilities are lower in fatigued muscles. The frequent injury trends in distance runners show that many of …

Organization and School Leadership Faculty Publications

This article examines the exercise practices of a group of faculty members at a regional university who for a decade have participated in their own racquetball league. These professors self-organized their exercise regimen and during the period of their participation have found significant benefits beyond the physical benefits, as a result. Through the production of reflective narratives focused on the impact of their racquetball participation, their self-reported data show two broad themes and numerous sub-themes that emerge from their exercise experience. They reveal significant health benefits, and they express more deeply the benefits of the positive social interaction that impacts …

The Effects Of Static Stretching On Muscular Hypertrophy During A Resistance Training Program, Zachary A. Martin

Senior Honors Theses

Abstract

Studies have shown that static stretching right before physical activity can negatively affect performance. In regards to weight lifting, it has been shown that static stretching immediately prior to lifting can decrease the maximum amount of weight that can be lifted. This study was created in order to determine if static stretching immediately prior to weight lifting over the course of nine weeks would result in smaller gains in muscle size compared to those who did not static stretch immediately prior to lifting over the course of nine weeks.
