Methods: A three-group pretest/posttest design was used and a survey was administered, at both the beginning and end of the semester, to all students enrolled in HEPE 129, live and …

The Effect Of Anterior Cruciate Ligament Recontruction On Lower Extremity Relative Phase Dynamics During Walking And Running, Max J. Kurz, Nikolaos Stergiou, Ugo H. Buzzi, Anastasios D. Georgoulis

Journal Articles

The purpose of this investigation was to use relative phase dynamics to evaluate gait in individuals with a reconstructed anterior cruciate ligament (ACL) during walking and running. Relative phase dynamics can describe the coordination strategies between the interacting segments at the lower extremity. Ten subjects who had undergone ACL reconstruction using the central third of their patellar tendon and ten healthy controls walked and ran on a treadmill at a self-selected pace. Relative phase dynamics were calculated for the foot–shank and shank–thigh coordinative relation- ships. Statistical differences between the groups were noted for the foot– shank relationship (p<0.05) during both walking and running and for the shank–thigh relationship (p<0.05) during walking. Our results indicate that current ACL reconstructive techniques may result in altered relative phase dynamics. These changes in relative phase dynamics could be related to a loss of sensory information about joint position and velocity that is typically provided by the intact ACL. Additionally, relative phase adaptations could be a learned response from the early stages of postsurgical rehabilitation. Relative phase dynamics provide quantitative information about the dynamic status of the ACL-reconstructed knee that cannot be gained from the conventional time-series evaluation of gait analysis data. Relative phase dynamics measures should supplement the conventional gait analysis measures that are used today for the clinical evaluation of the functional dynamic stability of the reconstructed knee. The examination of relative phase dynamics could be clinically important for the quantification of new ACL surgical interventions and of patient performance at various stages of rehabilitation. Further research should incorporate relative phase dynamics to understand the influence of ACL reconstruction on coordination and functional patient outcomes.

Effects Of Heat Removal Through The Hand On Metabolism And Performance During Cycling Exercise In The Heat, Andrew R. Hsu, Todd A. Hagobian, Kevin A. Jacobs, Hamdee Attallah, Anne L. Friedlander

Kinesiology and Public Health

OBJECTIVE: This two-part study tested the hypotheses that the use of a new cooling device, purported to extract heat from the body core through the palm of the hand, would (a) attenuate core temperature rise during submaximal exercise in the heat, thereby suppressing exercise-associated metabolic changes, and (b) facilitate a higher sustained workload, thus shortening the completion time of a time-trial performance test. METHODS: In Study 1, 8 male triathletes (age 27.9 ± 2.0 yrs, mass 77.2 ± 3.1 kg, VO₂peak 59.0 ± 4.1 ml x min^-1 x kg^-1) cycled for 1 hr at the …

Accessibility Of Foreign-Flagged Cruise Ships: Does The Americans With Disabilities Act Stop At U. S. Shores?, Joseph H. Huber, J. U. Stein, J. L. Mackool

Movement Arts, Health Promotion and Leisure Studies Faculty Publications

This article examines the accessibility of foreign-flag cruise ships for disabled people under the Americans With Disabilities Act. The majority of cruise ships have foreign registrations, thus avoiding payment of U.S. taxes and compliance with U.S. labor regulations. In large part, this is due to the age-old practice that the nation registering the ship also governs internal affairs of the ship. However, foreign-flag cruise ships are required to comply with U.S. regulations governing mandatory sanitation inspections of food preservation and preparation, as well as emergency operations, including fire alarm systems and lifeboat drills.

Excess Postexercise Oxygen Consumption And Interval Training, Shinichi Asano

Theses, Dissertations and Capstones

The effect of exercise intensity on excess postexercise oxygen consumption (EPOC) was determined in18 to 30 year old apparently healthy individuals. Subjects participated in 3 different exercise sessions; aerobic exercise, interval exercise (IE) and high intensity interval exercise (HIIE), on separate days. EPOC was measured one hour after each exercise while subjects were in supine position. ANOVA with repeated measurements was used to assess differences. The mean values (± SEM) for EPOC of aerobic exercise, IE and HIIE were 2.106(± 0.219), 2.846 (± 0.309) and 4.969 (± 0.522) l·hour -1. There was no significant difference (p < 0.05) between mean EPOC of aerobic exercise and IE, however, a significant difference (p < 0.05) was found in mean EPOC of HIIE when it was compared with both aerobic exercise and IE. These data suggest that exercise intensity has a significant effect on EPOC.

The Role Of Teachers' Self-Efficacy In Increasing Children's Physical Activity, James Frederick Roth

LSU Doctoral Dissertations

It is well documented that elementary school children do not participate in recommended amounts of physical activity, and that elementary physical education programs generally are unable to insure that children engage in appropriate amounts of activity. One solution to this dilemma is to increase children’s activity levels through collaborative efforts such as whole school programs involving the classroom teachers. If this approach is to be successful, it is important to investigate ways that elementary classroom teachers can be actively involved in school level programs that will ultimately increase children’s physical activity levels. Elementary classroom teachers are often responsible for at …

Baseline Measures Are Altered In Biomechanical Studies, Nikolaos Stergiou, Melissa Scott

Journal Articles

The purpose of this investigation was to examine if baseline measures are altered between conditions in biomechanical studies and to determine the need for baseline measurements in biomechanics. Ten runners were asked to run at varying speeds and obstacle heights. Baseline measures were acquired between all conditions. Right lower extremity kinematic and kinetic data were collected for all baseline trials and evaluated by both a group and a single subject analysis. The group analysis revealed significant differences between baselines only for the obstacle perturbation. The single subject analysis indicated that baseline measures are altered in a greater degree for kinematics …

Robotic Surgery Training And Performance, Kenji Narazaki, D. Oleynikov, Nikolaos Stergiou

Journal Articles

Background: To understand the process of skill acquisition in robotic surgery and to allow useful real-time feedback to surgeons and trainees in future generations of robotic surgical systems, robotic surgical skills should be determined with objective variables. The aim of this study was to assess skill acquisition through a training protocol, and to identify variables for the quantification of proficiency.

Methods: Seven novice users of the da Vinci Surgical System engaged in 4 weeks of training that involved practicing three bimanual tasks with the system. Seven variables were determined for assessing speed of performance, bimanual coordination, and muscular activation. These …

A Template For The Exploration Of Chaotic Locomotive Patterns, Max J. Kurz, Nikolaos Stergiou, Jack Heidel, E. Terry Foster

Journal Articles

Inverted pendulum and spring-mass models have been successfully used to explore the dynamics of the lower extremity for animal and human locomotion. These models have been classified as templates that describe the biomechanics of locomotion. A template is a simple model with all the joint complexities, muscles and neurons of the locomotor system removed. Such templates relate well to the observed locomotive patterns and provide reference points for the development of more elaborate dynamical systems. In this investigation, we explored if a passive dynamic double pendulum walking model, that walks down a slightly sloped surface (γγ was increased, …

Three-Dimensional Kinematics Of The Tibiofemoral Joint In Acl-Deficient And Reconstructed Patients Shows Increased Tibial Rotation, Anastasios D. Georgoulis, Stavros Ristanis, Constantina O. Moraiti, Argyris Mitsou, Manfred Bernard, Nikolaos Stergiou

Journal Articles

The study of the altered knee joint movement patterns that follow anterior cruciate ligament (ACL) rupture can be very insightful in the development of prevention and therapeutic strategies concerning this injury. This can be achieved through three-dimensional kinematic analysis, because it provides an objective evaluation in vivo of the knee joint function. It has been demonstrated that ACL-deficient patients develop functional adaptations (ie, quadriceps avoidance gait) and walk with the knee in a more extended position to compensate for the ACL loss. Furthermore, it has been shown that ACL rupture results in anterior tibial translation and excessive tibial rotation while …

Oxygen Uptake Efficiency Slope And Functional Physical Performance In Elderly Adults, Scott Eric Fuller

LSU Master's Theses

Background: The Oxygen Uptake Efficiency Slope (OUES) attained during submaximal treadmill exercise is a reliable index of cardiorespiratory capacity in older adults. This investigation compares OUES values derived during treadmill walking and performance of the Continuous Scale Physical Function Performance test (CS-PFP). Method: A Cosmed portable metabolic cart was used to collect breath gases in 36 older adults (age: 81.8 +/- 7.8 years). Twenty-one subjects performed both the incremental treadmill test and the CS-PFP while an additional 15 subjects performed the CS-PFP, only. Results: The regression of log Ventilation vs. VO₂ reveals similar correlations for the CS-PFP and treadmill …

Autonomic Nervous System Modulation Of The Heart Following A High Carbohydrate Liquid Meal, Calynn Davis Bunol

LSU Master's Theses

The involvement of the sympathetic nervous system in the pathology of obesity has long been a debate among researchers. Various methods of capturing the resting sympathetic activity as well as the response of the sympathetic activity elicited by the introduction of a meal or a bout of exercise in both lean and obese individuals have been investigated. This study examined the autonomic modulation of the heart following a high carbohydrate liquid meal in various body types. Twenty-five females with body mass indexes [weight (kg)/height²(m)] ranging from 19.3-39.5 were grouped according to relative basal energy expenditure adjusted for lean …

L-Glutamine Supplementation: Effects On Recovery From Exercise, Tavis Joseph Piattoly

LSU Master's Theses

Relatively little research has examined the benefits of glutamine for athletes engaged in heavy exercise training, despite a possible link between overtraining and glutamine. PURPOSE: To examine the influence of Glutamine on time to exhaustion and power after a prolonged bout of exercise. METHODS: Twelve men (Age: 19 to 30y) involved in cycle training were asked to participate in the study. All participants performed a Symptom-Limited Graded Exercise Test (SL-GXT) using the Astrand Cycle protocol. On a subsequent …

Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer

LSU Master's Theses

Age-related declines in vestibular function affect balance and coordination in older adults. Of perhaps equal importance, but less understood, are the potential implications of vestibular degeneration on cardiovascular homeostasis. Recent evidence suggests that the semi-circular canals, a section of the vestibular system, may be involved in the vestibulosympathetic reflex (VSR), but the extent to which the aging of the semi-circular canals interferes with cardiovascular homeostasis is unknown. Activation of the intact VSR results in increases in tonometric blood pressure (TBP) and heart rate (HR) as well as decreases in cardiac output (Q) and pre-ejection period (PEP). The purpose of this …

Differences Between Targeted And Measured Body Weight Support With The Usage Of A Body Weight Support System, Robin Cropper

LSU Master's Theses

The purpose of the study was to determine if the body weight support system (BWSS) maintains the targeted percentage of the subject's body weight support (BWS) during walking and to explore the relationship between unloading and ground reaction force. Sixteen healthy college students (mean age: 22 years old) were recruited as subjects. Tests were conducted using an instrumented treadmill with a BWSS. The BWSS harness was secured around the lower abdomen and pelvis of each subject for effective body weight support. Vertical ground reaction force was measured by force platforms embedded in the treadmill. A force sensor was attached to …

Body-Induced Vortical Flows: A Common Mechanism For Self-Corrective Trimming Control In Boxfishes, Ian K. Bartol, Morteza Gharib, Paul W. Webb, Daniel Weihs, Malcolm S. Gordon

Biological Sciences Faculty Publications

Boxfishes (Teleostei: Ostraciidae) are marine fishes having rigid carapaces that vary significantly among taxa in their shapes and structural ornamentation. We showed previously that the keels of the carapace of one species of tropical boxfish, the smooth trunkfish, produce leading edge vortices (LEVs) capable of generating self-correcting trimming forces during swimming. In this paper we show that other tropical boxfishes with different carapace shapes have similar capabilities. We conducted a quantitative study of flows around the carapaces of three morphologically distinct boxfishes (spotted boxfish, scrawled cowfish and buffalo trunkfish) using stereolithographic models and three separate but interrelated analytical …

Persistent Sympathetic Activation During Chronic Antihypertensive Therapy, Qi Fu, Rong Zhang, Sarah Witkowski, Armin Arbab-Zadeh, Anand Prasad, Kazunobu Okazaki, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

Previous studies have demonstrated that antihypertensive treatment resets baroreflex control of heart rate (HR) and increases cardiac vagal baroreflex sensitivity. However, it is uncertain whether baroreflex control of muscle sympathetic nerve activity (MSNA) also resets after treatment. We tested the hypothesis that chronic antihypertensive therapy alters baroreflex regulation of MSNA in patients with untreated moderate hypertension. Seven newly diagnosed patients with systolic blood pressure (BP) of 159 5 mm Hg (mean SE) and diastolic BP of 103 4 mm Hg were studied before and after 1 to 2 weeks ´ and 3 months (chronic) of antihypertensive treatment with losartan– hydrochlorothiazide …

Is The Ability To Regenerate Damaged Skeletal Muscle Genetically Determined? : Can Allelic Variation In The Gene, Pax7, Explain Observed Differences In Recovery Of Force Following Damage By Eccentric Exercise?, Zoran Groznica

Theses : Honours

High force eccentric muscle actions, during forcibly lengthening contracting muscle, have been found to produce pronounced muscle damage, especially if exercise is unaccustomed. A cascade of events is initiated in order to repair damaged skeletal muscle tissue including degeneration and regeneration processes. For the duration of muscle regeneration, satellite cells are the primary source of new myoblasts in adult muscle. This process requires activation of quiescent mononucleated satellite cells which proliferate, differentiate and fuse together to form fully functional muscle fibres. The satellite cells are specified by the gene, Pax7, during development. Experimental studies of Pax7 null mice that lack …
