Firefighters require a high level of physical fitness in order to meet the demands of their profession. While physical fitness testing is required to join the department, firefighters are not subject to further formal exercise testing throughout the duration of their careers. Active, career firefighters were tested on a variety of physical fitness measures related to body composition, strength, power, and endurance over three testing sessions. 49 firefighters (40.5 ± 8.3 yr, 89.5 ± 13.0 kg, 27.8 ± 3.6 kg/m2) were found to have a resting heart rate of 57.7 ± 8.2 bpm, blood pressure of 121.5 ± 11.9/71.5 ± …

Leg Strength And Lean Mass Symmetry Influences Kicking Performance In Australian Football, Nicolas H. Hart, Sophia Nimphius, Tania Spiteri, Robert U. Newton
Research outputs 2014 to 2021
Differential loading patterns during game-based participation may produce or exacerbate strength imbalances between the lower limbs. It is currently unknown whether such imbalances are functionally beneficial or detrimental to performance. This study assessed the influence of lower limb strength and lean mass symmetry on kicking accuracy in Australian Football. Thirty-one Australian footballers were required to perform a kicking assessment, producing ten drop punt kicks over twenty metres to a player target. Athletes were subsequently separated into accurate (n = 15) and inaccurate (n = 16) groups, with lower-body lean mass assessed using whole body DXA scans, and lower-body strength assessed …
Methionine Restriction-Induced Metabolic Changes In C57bl6j Mice,

Louisiana State University and Agricultural and Mechanical College
Methionine Restriction-Induced Metabolic Changes In C57bl6j Mice, Cory Christopher Cortez
LSU Master's Theses
Introduction: Eighty percent restriction of normal dietary methionine (MR) intake has been shown to increase energy expenditure and attenuate the rate of adiposity gain in rodents, despite a paradoxical increase in energy intake. Energy expenditure in rats was shown to increase, even though physical activity level stays the same. This observation suggests that metabolic mechanisms account for the majority of increased energy expenditure measured in methionine restricted animals. Purpose: To observe and document the onset of physiological effects brought about and to determine the mechanistic role of the skeletal muscle on MR-induced metabolic changes in the C57BL6J mouse. Methods: C57BL6J …

The Control Of Amplitude And Direction In Bimanual Coordination, Zhujun Pan
LSU Doctoral Dissertations
Spatial coordination of bimanual movements is important when performing daily activities. Whereas, older adults and individuals with Parkinson’s disease (PD) commonly show difficulties in temporally coordinating the hands in bimanual coordination tasks, the effects of aging and Parkinson’s disease on the quality of spatial coordination between the hands are unclear. Thus, the present work investigated the impact of older age and PD on the spatial interference in a bimanual task in which 48 right hand-dominant participants (16 young adults, 16 older adults and 16 individuals with PD) drew simultaneously two lines with both hands with varied movement amplitudes (3 and …

Theses and Dissertations (Comprehensive)
Academics and practitioners have only just begun to delve into the health benefits of outdoor activities in the last few years. In general, the forested settings of these activities have been documented to decrease stress levels, increase recovery rates from disease, and lessen the symptoms of mental illnesses (Kuo & Faber Taylor, 2004). It is believed that the natural environment acts as a setting where humans can engage in physical activity, aesthetic experiences, and social interactions that, in turn, release stress and lead to improved well-being (Bird, 2012). Currently, however, children are experiencing limited exposure to nature and which has …

Laterality Across The Lifespan: The Effects Of Task Complexity, Nicole Williams
Theses and Dissertations (Comprehensive)
The current study aimed to build on the work of Gooderham & Bryden (2013) by comparing the effects of task complexity on hand selection across the lifespan. It was hypothesized that the increasing complexity of a task would override a biomechanically efficient movement such that participants would use only the preferred hand to complete the task. It was also hypothesized that older adults would perform similarly to young children with respect to switch points in space. Four age groups of participants (3-7 year olds, 8-12 year olds, 18-25 year olds and adults over 70 years) completed the newly designed Hand …

Quantifying Cognitive Function In Concussed Athletes Before And After Acute Exercise Using A Choice Reaction Time Task, Stephanie A. Ramautar M.Sc., Michael E. Cinelli Ph.D.
Theses and Dissertations (Comprehensive)
Following a concussion, cognitive deficits have been shown to last longer than symptom resolution. Currently clinicians rely heavily on symptom emergence following the fundamental exercises of the return to play (RTP) protocol, which may leave athletes at risk of returning to play too early if cognitive deficits have not been detected. The purpose of this study was to assess the effects of exercise on choice reaction time (CRT) both at rest and following an acute exercise in 3 populations: non-concussed (NC), recently concussed (RC), and post-concussion syndrome (PCS) individuals. A CRT task in the form of an iPad application measured …

Transport, Deposition, And Hygroscopic Growth Of Diverse-Regime Aerosols In Human Respiratory Airways Of Varying Ages, Jongwon Kim
Theses and Dissertations
Determining how many inhaled aerosols deposit in human respiratory airways and where they deposit (i.e., respiratory dosimetry) are of critical importance in a number of fields. Applications of respiratory dosimetry modeling include evaluating health effects of inhaled pollutants, establishing environmental exposure standards, and developing effective techniques for delivering pharmaceutical aerosols to the lung. However, the manifold characteristics of aerosols coupled with the complexity of respiratory tract make such analysis a challenging task as well as a highly multidisciplinary effort, entailing expertise from medicine, engineering, and physiology. In this study, three major factors that affect particle transport and depositions were systematically …

Flexibility In Food Extraction Techniques In Urban Free-Ranging Bonnet Macaques, Macaca Radiata, Madhur Mangalam, Mewa Singh
Journal Articles
Non-human primate populations, other than responding appropriately to naturally occurring challenges, also need to cope with anthropogenic factors such as environmental pollution, resource depletion, and habitat destruction. Populations and individuals are likely to show considerable variations in food extraction abilities, with some populations and individuals more efficient than others at exploiting a set of resources. In this study, we examined among urban free-ranging bonnet macaques, Macaca radiata (a) local differences in food extraction abilities, (b) between-individual variation and within-individual consistency in problem-solving success and the underlying problem-solving characteristics, and (c) behavioral patterns associated with higher efficiency in food extraction. When …

INTRODUCTION: Energy drinks have become the soft drink of this millennium. They are commonly available everywhere including stores, schools and fitness centers. Yet, the effects of energy drinks, on metabolism at rest and during exercise, receive little attention. Ingredients in energy drinks such as caffeine and taurine are sympathetic stimulants and increase heart rate and blood pressure. However, it is unclear as to whether or not these effects actually improve exercise performance. Redbull is an example of an energy drink that is often consumed with the idea that it will improve performance during an exercise workout. PURPOSE The purpose of …

The Effects Of Caffeine On Blood Lactate Levels During Submaximal Exercise, Sara Cleveland
Kinesiology Student Research - Archive
INTRODUCTION: Blood lactate concentration reflects the balance between lactate production and clearance. It is considered a marker of exercise intensity and muscle glycolysis. It is expressed in mmol/L of lactate found in the plasma of blood. Research shows that caffeine, a stimulant with ergogenic properties, increases blood lactate levels. It is also shown to improve aerobic performance and increase time to exhaustion during exercise. The physiological underpinnings of caffeine-provoked endurance performance gains are not yet fully understood but may be related to enhanced calcium availability, adenosine receptor antagonism and consequential reductions in pain and perceived exertion, and augmented lipolysis and …

Introduction. Research shows that rhythmic exercise changes in serotonin, epinephrine, norepinephrine and acetylcholine levels all affect cortical arousal and cognitive function (Potter & Keele, 2005). There are many reasons why the brain is affected during exercise. Some of these include: increased glucose, oxygen and nutrient levels to the brain. Exercise has been shown to enhance cognitive function in both short and long term memory. However, when the body is put under a large amount of physical stress, less oxygen is left in the brain due to the fact that the muscles require more of that oxygen and glucose. Does this …

INTRODUCTION: Caffeine has become the most widely used drug in the world. This xanthene derivative causes an increase in catecholamines circulating throughout the blood, and is commonly used by athletes looking for an increase in athletic performance. Besides having a stimulating effect on the cardiovascular and nervous system, many report a decrease in their levels of perceived exertion while performing exercise in conjunction with the drug. Blood lactate is a common way to quantify objectively the levels of exertion an athlete may be experiencing during exercise, as it is shown to increase linearly with perceived exertion and muscular fatigue. Additionally, …
