Efficacy And Safety Of A Modular Multi-Modal Exercise Program In Prostate Cancer Patients With Bone Metastases: A Randomized Controlled Trial, Daniel Galvao, Dennis R. Taaffe, Prue Cormie, Nigel Spry, Susan K. Chambers, Carolyn Peddle-Mcintyre, Michael Baker, James Denham, David Joseph, Geoff Groom, Robert Newton

Research outputs 2011

Background: The presence of bone metastases has excluded participation of prostate cancer patients in exercise intervention studies to date and is also a relative contraindication to supervised exercise in the community setting because of concerns of fragility fracture. However, this group of patients often have developed significant muscle atrophy and functional impairments from prior and continuing androgen deprivation that is exacerbated by subsequent and more intensive interventions such as chemotherapy. The aim of this study is to determine the efficacy and safety of a modular multi-modal exercise program in prostate cancer patients with bone metastases. Methods/Design: Multi-site randomized controlled trial …

Circadian Rhythms In Exercise Performance: Implications For Hormonal And Muscular Adaptation, Weipeng Teo, Michael Newton, Michael Mcguigan

Research outputs 2011

Almost all physiological and biochemical processes within the human body follow a circadian rhythm (CR). In humans, the suprachiasmatic nucleus regulates sleep-wake cycle and other daily biorhythms in line with solar time. Due to such daily physiological fluctuations, several investigations on neuromuscular performance have reported a distinct CR during exercise. Generally, peak performances have been found to occur in the early evening, at approximately the peak of core body temperature. The increase in core body temperature has been found to increase energy metabolism, improve muscle compliance and facilitate actin-myosin crossbridging. In addition, steroidal hormones such as testosterone (T) and cortisol …

Effects Of A Simulated Tennis Match On Lymphocyte Subset Measurements, Holly Kell

Masters Theses & Specialist Projects

Research has shown that maximal exercise has a significant effect on cells of the immune system. Specifically, lymphocyte count increases during exercise and decreases to a value lower than baseline following an acute exhaustive bout of exercise. The overall lymphocyte response is well characterized, however, the ability of exercise to affect lymphocyte subfractions is unknown to our knowledge. The purpose of this study was to assess and evaluate the affects of a simulated tennis match across two sessions on lymphocyte subsets.

Initial measurements such as age, height, weight, skinfold analysis, and heart rate were recorded for each player, as well …

Caffeine Supplementation And Moderate Intensity Exercise Modulates The Cytotoxic Lymphocyte Subset (Cd+8) In Naive And Tolerant Individuals, Elizabeth Ann Fedor

Masters Theses & Specialist Projects

The purpose of this investigation was to determine the effects of caffeine supplementation on caffeine tolerant and caffeine naïve individual’s lymphocyte counts, apoptosis and migration levels. In addition, effects of exercise on post-caffeine ingestion lymphocyte counts, apoptosis and migration levels were determined. It was hypothesized that caffeine would alter the immune system cell counts, but that exercise would be able to restore the immune system to homeostasis. Seventeen Western Kentucky University students were tested (males n=7, females n=10; n=7: caffeine tolerant= 200mg or more per day group, n=9: caffeine naïve= 50mg or less per day group). In this double-blind investigation, …

Convergent Validity Between Field Tests Of Isometric Core Strength, Functional Core Strength, And Sport Performance Variables In Female Soccer Players, Jeffrey Scott Wagner

Boise State University Theses and Dissertations

Introduction: Previous research has failed to definitively explain the role that core fitness plays during sport performance. Movements of sport performance require the core musculature to simultaneously provide spinal stability while producing external forces that aid limb movement. The core is central to most kinetic chains; therefore, a better understanding of core function during sport should help to benefit performance. Purpose: The purpose of this study was to compare tests of isometric core strength that evaluate the ability of the core to provide a stable base of support, and tests of concentric functional core strength that evaluate the ability of …

The Physical Activity Patterns And Constraints Of Diverse Female College Students, Kathleen Victoria Minkel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diverse college aged females from a public university in the southwest were asked to participate in an online survey to determine their constraints to physical activity, as well as their current activity level. The groups were compared to establish the differences among the minority groups. Raymore, Crawford, and Godbey’s Hierarchical Model of Constraints was used as a framework when creating the survey. Data analysis showed only one significant difference among the racial/ethnic groups, when looking specifically at the intrapersonal, interpersonal, and structural constraints categories. Hispanic women differed significantly from Caucasian women in their perception of interpersonal constraints on their physical …
