Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen

LSU Master's Theses

The autonomic nervous system (ANS) modulation of the heart is of clinical importance because of its relevance to risk of life threatening arrhythmic events. Decomposition of heart rate variability (HRV) has been used to quantify ANS control of the heart. The traditional method for frequency analysis has involved the use of fast Fourier transformation (FFT). However, heart rate data typically violate assumptions of the FFT. Therefore, the assessment of HRV may benefit from other, potentially more suitable, mathematical approaches. For example, the discrete wavelet transformation (DWT) appears to have promise with respect to its ability to discriminate between healthy and …

Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone

LSU Master's Theses

The reliability of wavelet analysis (DWT), of heart rate variability during rest and exercise was examined for this study. All twenty-three participants visited the lab on two separate occasions no less than four weeks apart. All twenty-three participants were subjected to the spontaneous breathing (SB1), and HG60 exercise condition. Of those twenty-three participants, nine performed the HG20 exercise condition as well. It was found that during the SB1 condition, the R-R intervals were fairly reliable between days. However, the reliability of all the HRV parameters (SDNN, spectral components and wavelet components) were quite poor. Interestingly, however, during HG20, the reliability …

A Comparison Of Self-Report And Performance-Based Measures Of Physical Function In Older Adults, Amy Elizabeth Dunbar

LSU Master's Theses

The purpose of this thesis was to examine the associations between perceived quality of life (QOL)and self-report and performance-based measures of function. An additional purpose of this thesis was to determine whether the afore-mentioned tests could differentiate between independent-living and assisted-living older adults. A total of 36 residents, independent-living (n=22) and assisted-living (n=14), of a continuing care retirement community (age range=65-94) completed the study. Perceived QOL was assessed using the SF-36 and Nottingham Health Profile. The Barthel Index and Functional Status Index (FSI) were used to assess Activities of Daily Living (ADLs). Physical function was measured using the reduced Continuous …

Comparison Of Black And White Elderly Women On Muscle Mass Bone Mineral Density And Balance., Tyanez Jones

Electronic Theses and Dissertations

Few studies have compared balance between aging black (BW) and white women (WW) and examined its relationship to muscle mass and bone mineral density (BMD). Nineteen BW and 56 WW between 60-91 years participated. Upper and lower body strength, body composition, BMD, volitional and non-volitional control of dynamic balance, and physical activity ratings were assessed. There were no differences in strength between the groups. A trend was reported for total body BMD (p=0.07). WW exhibited better control of rapid volitional movements, in the limits of stability and rhythmic weight shift tests. The relationships of strength and muscle mass to BMD …

Area-Level Characteristics And Smoking In Women, Marilyn Tseng, Karin Yeatts, Robert Millikan, Beth Newman

Kinesiology and Public Health

Objectives. This study examined whether area-level characteristics are associated with individual smoking behavior among women.

Methods. Analyses included 648 women enrolled as control patients in the Carolina Breast Cancer Study (1993–1996). Smoking and covariate information was obtained from interviews. Area-level characteristics included census block-group education level, poverty, unemployment, car–home ownership, crowding, and, for 431 women, city-level crime rates.

Results. In multivariate logistic regression models, no area characteristics were clearly associated with a history of smoking. Among those who had ever smoked, continued smoking was associated with living in low-education areas (odds ratio [OR] = 1.7, 95% confidence interval [CI] = …

Critical Analysis Of Cerebrovascular Autoregulation During Repeated Head-Up Tilt., R L Hughson, M R Edwards, D D O'Leary, J K Shoemaker

Kinesiology Publications

BACKGROUND AND PURPOSE: Cerebrovascular autoregulation has been described with a phase lead of cerebral blood flow preceding changes in cerebral perfusion pressure (CPP), but there has been less focus on the effect of CPP on cerebral vascular resistance. We investigated these relations during spontaneous fluctuations (control) and repeated head-up tilt.

METHODS: Eight healthy adults were studied in supine rest and repeated tilt with 10-second supine, 10 seconds at 45 degrees head-up tilt for a total of 12 cycles. Cerebral blood flow was estimated from mean flow velocity (MFV) by transcranial Doppler ultrasound, CPP was estimated from corrected finger pressure (CPP(F)), …

Fundamental Dietary Patterns And Their Correlates Among Us Whites, Marilyn Tseng, Robert F. Devellis

Kinesiology and Public Health

A social history of eating habits in the United States (1) suggests that there are 2 fundamental US dietary patterns. The first, characterized by beef or pork, while flour bread, and potato consumption, is grounded in British culinary heritage. The second, characterized by fruits and vegetables consumed as "protective" foods, that is, to avoid illness, is a result of the development of nutrition science, the growth of good and advertising industries, and efforts of World War 1 food conservation programs. To confirm the occurrence of these 2 dietary patterns and their sociodemographic and lifestyle correlates, we used principal components analysis …

Intralimb Coordination Following Obstacle Clearance During Running: The Effect Of Obstacle Height, Nikolaos Stergiou, Shane D. Scholten, Jody L. Jensen, Daniel Blanke

Journal Articles

The purpose of this study was to investigate the different coordination strategies used following obstacle clearance during running. Ten subjects ran over a level surface and over obstacles of six different heights (10, 12.5, 15, 17.5, 20 and 22.5% of their standing height). Analysis based upon the dynamical systems theory (DST) was used and the phasing relationships between lower extremity segments were examined. The results demonstrated that the increasing obstacle height elicited behavioral changes. The foot and the leg became more independent in their actions, while the leg and the thigh strengthened their already stable relationship. The 15% obstacle height …

A Comparison Of The Effects Of Interval Training Vs. Continuous Training On Weight Loss And Body Composition In Obese Pre-Menopausal Women., Jeffrey Warren King

Electronic Theses and Dissertations

The purpose of this study was to investigate the role exercise intensity plays in reducing body weight and percent body fat in overweight women. Subjects were randomized to either a high intensity interval training group (IT) or a lower intensity steady state training group (ST). Each group exercised 3 times per week for 8 weeks and expended 300 kcal per exercise session. VO₂max, body composition, and resting metabolic rate (RMR) were measured pre and post training. RMR was measured after exercise at week 2 to see if intensity levels affected RMR. VO₂max and body composition improved …

The Cardiovascular Effects Of Resistance Exercise Training On Orthostatic Intolerance In Elderly Individuals., Lynn P. Rhea

Electronic Theses and Dissertations

One of the age-related changes associated with normal aging is the inability to maintain normal blood pressure homeostasis, a common clinical condition known as orthostatic intolerance. There are little data on the effects of strength training in healthy adults and orthostatic intolerance, and only one study on strength training and elderly adults diagnosed with orthostatic intolerance. Therefore, the purpose of the present study was to evaluate the effects of resistance training on the cardiovascular respones of elderly individuals during an orthostatic challenge.

Thirteen subjects were assigned to either a resistance (RES; n=7; 66±5 yrs.) or a control (CON; n=6; 71±6 …

Determinants Of Teachers' Intentions To Teach Physically Active Physical Education Classes, Jeffrey J. Martin, Pamela Hodges Kulinna, Robert C. Eklund, Brett Reed

Kinesiology, Health and Sport Studies

The purpose of the present investigation was to examine determinants of teachers' intentions to teach physically active physical education classes (i.e., spend at least 50% of class time with the students engaged in moderate to vigorous physical activity). Based on the theories of reasoned action, planned behavior, and self-efficacy, a model was examined hypothesizing that teachers' intentions were determined by subjective norm, attitude, perceived behavioral control, and self-efficacy. Using hierarchical regression analyses, the theories of reasoned action and planned behavior were supported by accounting for 65% of the variance in intention due to the main effects of attitude and subjective …

Childhood Obesity And Its Relationship To Sedentary Behavior Patterns Vs. Other Independent Risk Factors Of Obesity Among Navy Dependent Adolescents, Shaye Lauren Arluk

Human Movement Studies & Special Education Theses & Dissertations

Background According to data gathered in the NHANES 1999 survey 14% of American children are now classified as obese, a 60% increase in prevalence from the NHANES II survey in 1976. Multiple research studies have looked at the role of dietary intake, heredity, and physical activity participation as independent risk factors of obesity with mixed results. However, sedentary behavior patterns, which have markedly increased in the past ten years, have not been extensively studied in relation to childhood obesity. The goal of this study was to focus on the relationship between various sedentary behaviors and childhood obesity.

Motor Control Of Human Gait: A Dynamic Systems Perspective, Gary P. Austin

All PTHMS Faculty Publications

Fundamentally, gait permits humans to move intentionally and independently from place to place and to interact with the environment. Human gait, as ordinary as it may seem, is a wonderful illustration of the complex, yet precise action emerging from the interplay of the organism and the environment. As a result of this precision, the locomotor system functions safely and efficiently regardless of the ever-varying environmental conditions. Successful movement ultimately depends on the control, coordination, and integration of the many resources offered by the locomotor system and the environment.

Isokinetic Dynamometer Versus A Multi-Axial Stability Platform In The Proprioception And Strength Training Of The Peroneal Muscle Group, Eric Johnson

Theses, Dissertations and Capstones

Ankle injuries are the most common and frequent occurring injuries in sports today (Feuerbach, Grabiner & Koh, 1994). Ankle sprains usually occur in athletes that are participating in running or jumping activities. Injuries to the ankle joint represent about 20% of all sports related injuries, and 15% of all time lost injuries (Payne, Berg, & Latin, 1997). The majority of the sprains to the ankle occur to the lateral ligamentous structures due to the forcefully plantar flexion and inversion of the talocrural joint. This inversion mechanism accounts for 85% of all ankle sprains (Kinzey, Ingersoll, & Knight, 1997). Often after …

Exploration Of Federal Sport Policy On Youth Elite Sport In Canada: A Case Study Of Gymnastics Canada Gymnastique, Laura Misener

Kinesiology Publications

A case study of Gymnastics Canada Gymnastique aided in creating a contemporary framework for youth sport policy development. Youth involved in elite sport are in a subsidiary position to those who control the sport environment, and therefore are in need of certain levels of protection. High performance youth athletes may be subject to numerous problems such as competitive anxiety, disrupted family life, and excessive physiological and psychological stress. In order to explore these issues in relation to federal sport policy, the following sub-problems were identified: (a) What are the process(es), legitimation(s) (rationale) and attribution(s) (strategies for action) of federal government …

Aerobic Respiratory Costs Of Swimming In The Negatively Buoyant Brief Squid Lolliguncula Brevis, Ian K. Bartol, Roger Mann, Mark R. Patterson

Biological Sciences Faculty Publications

Because of the inherent inefficiency of jet propulsion, squid are considered to be at a competitive disadvantage compared with fishes, which generally depend on forms of undulatory/oscillatory locomotion. Some squid, such as the brief squid Lolliguncula brevis, swim at low speeds in shallow-water complex environments, relying heavily on fin activity. Consequently, their swimming costs may be lower than those of the faster, more pelagic squid studied previously and competitive with those of ecologically relevant fishes. To examine aerobic respiratory swimming Costs, O₂ consumption rates were measured for L. brevis of various sizes (2-9 cm. dorsal mantle length, DML) …

LSU Doctoral Dissertations

This is a series of 3 experiments in the area of vasoreactivity. The first study investigated the stability and reproducibility of brachial artery flow-mediated dilation (BAFMD). Twenty-six healthy volunteers underwent 3 scans on 2 days, performed by 2 ultrasonographers, and analyzed by 2 readers. All subjects were tested between 7 and 11am after refraining from food and exercise. Average baseline diameter was 3.48±0.53mm, which increased to 3.71±0.57mm (6.58±4.15%) at peak dilation. ICCC's for days, testers and readers were 0.9188, 0.9394, and 0.8982 respectively. To detect a difference in vasoreactivity of 60% (two-tailed), e.g. 5% vasodilation versus 8% vasodilation, at 90% …

Determining The Termination Percentage Of Heart Rate Maximum For Submaximal Testing, Julia A. Valentour

College of Graduate Studies: Theses & Dissertations (1964–2006)

BACKGROUND: In the Fourth Edition of the American College of Sports Medicine's Guidelines for Exercise Testing and Prescription (1991). the protocol for the ACSM's submaximal bike test was to terminate the test at 65-70% of the age predicted maximal heart rate. In the Fifth Edition, this was changed to 85% of the age-predicted maximal heart rate.

OBJECTIVES: The purpose of this study was to find out, by using the ACSM submaximal cycle ergometer test (see Appendix A) if the 85% heart rate maximum termination provides a more accurate estimate of maximal aerobic capacity than the 70% heart rate maximum termination. …
