Effects Of Curcumin And Fenugreek Soluble Fiber Supplements On Submaximal And Maximal Aerobic Performance Indices In Untrained College-Aged Subjects, Jensen Goh Zhong Sheng

Theses and Dissertations--Kinesiology and Health Promotion

Submaximal exercise performance is, in part, limited by the accumulation of metabolic byproducts and energy system capacities. Curcumin and the combination of curcumin and fenugreek soluble fiber (CurQfen^®) have been shown to increase endogenous antioxidants and metabolic byproduct clearance as well as reduce inflammation and lipid peroxidation, and therefore, may enhance submaximal aerobic thresholds. In addition, there is evidence that the galactomannan component of fenugreek, used to enhance bioavailability of curcumin, may also have potential physiological effects related to the up regulation of free fatty acid oxidation Therefore, the purpose of this study was to examine the effects …

Chronic Low Intensity Continuous And Interval Training Prevent Heart Failure-Related Coronary Artery Stiffness, An Ouyang

Theses and Dissertations--Kinesiology and Health Promotion

Heart failure (HF) induced by aortic pressure over-load is associated with increased coronary artery stiffness. Perivascular adipose tissue (PVAT) and advanced glycation end products (AGE) both promote arterial stiffness. However, the mechanisms by which coronary PVAT promotes arterial stiffness and the efficacy of exercise to prevent coronary stiffness are unknown. The present study hypothesized both chronic continuous and interval exercise training would prevent coronary artery stiffness associated with inhibition of PVAT secreted AGE. Yucatan mininature swine were divided into four groups: control-sedentary (CON), aortic-banded sedentary heart failure (HF), aortic-banded HF continuous exercise trained (HF+CONT), and aortic-banded HF interval exercise trained …

Muscle Synergy During A Single Leg Standing Test In Ambulatory Children With Cerebral Palsy, Brennan L. Smith

Theses and Dissertations--Kinesiology and Health Promotion

INTRODUCTION: Cerebral Palsy (CP) is a sensorimotor disorder characterized by dysfunctional motor coordination, balance problems, and loss of selective motor control. Motor coordination exhibited as co-contraction, has been subjectively quantified using gait analysis, but recent studies have begun to objectively analyze the amount of co-contraction by collecting electromyography (EMG) data. Center of pressure excursion (COPE) measurements collected during a single leg standing test (SLST) have shown to be more valid measurements of balance in populations with motor disabilities than a SLST alone. A recent study has correlated increased COPE velocity with a lower fall risk as determined by reported fall …

Self-Reported Adherence To Physical Activity For Cancer Survivors: An Update From The 2015 Nhis Database, Andrew Jackson Shearer

Theses and Dissertations--Kinesiology and Health Promotion

Cancer is the second leading cause of death in America. It’s been suggested that regular physical activity (PA) can improve health outcomes in cancer survivors. An estimate from BRFSS data (2009) suggested that 47% of all cancer survivors met recommended guidelines and that this estimate was not different from the population at large (48%). Several factors were examined from these BRFSS data to determine whether subgroups of survivors existed who might benefit from interventions aimed at improving their PA status. The purpose of this investigation was to obtain more recent estimates of adherence to established PA guidelines for cancer survivors. …

Central And Peripheral Weight Gain Affect Trunk Kinematics And Lower-Extremity Muscle Activation Differently During Sit-To-Stand, Michelle Christine Walaszek

Theses and Dissertations--Kinesiology and Health Promotion

Background: Obesity-induced alterations in biomechanics and muscle recruitment during activities of daily living, such as sit-to-stand (STS) are often attributed to increases in adipose tissue (AT) mass. Central or peripheral distribution of AT may differently affect biomechanics and muscle recruitment.

Methods: Fifteen healthy, normal weight (BMI 22.4 ± 1.9 kg/m², 24.1 ± 4.2 years) subjects volunteered. External loads equivalent to a 5 kg/m² BMI increase were applied in three conditions: unloaded (UN), centrally loaded (CL), and peripherally loaded (PL). Subjects completed three successful STS movements in a backless chair under each load condition in random order. Motion …

Lifestyle Contributors To Cardiovascular Disease Risk, Adam J. Berrones

Theses and Dissertations--Kinesiology and Health Promotion

Aortic stiffness is an independent risk factor that has prognostic value regarding future cardiovascular disease (CVD) events such as myocardial infarction, strokes, and heart failure. Although death rates due to coronary heart disease have declined in recent years, the leading global killer remains CVD and prevalence is still high. Understanding lifestyle contributors associated with aortic stiffness would provide the public with insight into targeting key health-related behaviors.

Electromyographic (EMG) activity was measured in the gluteus maximus, vastus lateralis, gastrocnemius medialis, and tibialis anterior during the VJ trials. Repeated measures ANOVA were used to compare VJ and EMG outcomes across conditions. A Bonferroni correction was used to account for multiple post-hoc …

The Effect Of Fluid Periodization On Athletic Performance Outcomes In American Football Players, Christopher W. Morris

Theses and Dissertations--Kinesiology and Health Promotion

For decades strength and conditioning professionals have been seeking optimal training volumes and intensities to yield maximum performance outcomes without the onset of injury. Unfortunately, current studies apply experimental training techniques without considering the individuals’ response to the imposed training load. Due to the vast genetic variability and extraneous environmental factors that affect one’s ability to recover, results from such studies are controversial and inconclusive. Athlete monitoring systems offer an objective assessment that is purported to evaluate an individual’s physiological readiness to adapt to an overload stimulus and thus allow for daily manipulations in training loads (i.e., fluid periodization). However, …

The Effects Of Spinal Manipulative Therapy On Isokinetic Strength And Postactivation Potentiation, Grant D. Sanders

Theses and Dissertations--Kinesiology and Health Promotion

Spinal manipulative therapy (SMT) is a therapeutic procedure employed by various healthcare practitioners for alleviating acute and chronic musculoskeletal complaints. This form of treatment is also delivered to enhance the performance and augment the rehabilitation of athletes. However, despite research findings alleging the strength-modulating effects of SMT alongside numerous professional athletes’ positive anecdotal claims concerning its results, the physiological processes to explain its effects remain largely unexplained. Therefore, the purpose of this work was to investigate the effects of SMT in a college-aged sample population with two experiments.

The first study examined the effect of SMT targeting the lumbosacral region …
