A Difference In Aerobic And Anaerobic Energy Costs During Weightlifting, Sarah Shapiro, Deline Dwelly

Thinking Matters Symposium Archive

Energy expenditure is usually estimated by total oxygen uptake. However, with weightlifting, very little oxygen is utilized during the lift. The majority of oxygen uptake happens during recovery (Excess Post-Exercise Oxygen Consumption, EPOC). The purpose of this study is to determine the significance of the anaerobic and EPOC phases during weightlifting exercises in estimation of total energy cost. We gathered data from 42 subjects (60 averaged trials) aging between 18 and 35 years. Each subject chose a comfortable weight and lifted to a cadence of 1.5 sec up and 1.5 sec down. Tests were given on two different occasions. We …

Thinking Matters Symposium Archive

The purpose of this project is to examine an exercise-­‐based approach to rehabilitating an athlete with medial tibial stress syndrome. It presents specific exercises that can be used, and focuses on resolving the core of the problem instead of just addressing the symptom. This review attempts to provide a long-­‐term solution rather than providing a quick fix.

The Effects Of Land-Based Plyometric Training And Timing Of Plyometrics Fusion On Selected Acute Swim Performance Measures, Joshua R. Beard

Theses & Honors Papers

The purpose of this study is twofold: 1) to determine the effect of land-based plyometric training on selected acute swim performance measures; and 2) to determine the effect of timing on acute swim performance measures when incorporating plyometric training into a single training session. The guiding hypothesis for this project is that the land-based plyometric training will have a positive impact on acute swim performance, in particular when the plyometrics are performed pre-training session (compared to mid-training session).

Safety Policy And Procedure In Ohio High School Basketball, Issa Walker

Master of Public Health Program Student Publications

There are projected to be seven million high school adolescents from roughly 20,000 high schools who partake in local sports programs annually. Children and adolescents are increasingly participating in sports, and this expanding involvement brings forth issues regarding possible risks of sports-related injury (Vanderlei et al. 2013). Although the involvement in sports is proven to be advantageous for the physical and mental well-being of human beings, injury rates are a public health concern. In the United States, young athletes are responsible for more than two million injuries, 500,000 physician visits, and 30,000 hospitalizations per year (Centers for Disease Control & …

Comparison Of Functional Network Connectivity For Passive-Listening And Active-Response Narrative Comprehension In Adolescents, Yingying Wang, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty Publications

Comprehension of narrative stories plays an important role in the development of language skills. In this study, we compared brain activity elicited by a passive-listening version and an active-response (AR) version of a narrative comprehension task by using independent component (IC) analysis on functional magnetic resonance imaging data from 21 adolescents (ages 14–18 years). Furthermore, we explored differences in functional network connectivity engaged by two versions of the task and investigated the relationship between the online response time and the strength of connectivity between each pair of ICs. Despite similar brain region involvements in auditory, temporoparietal, and frontoparietal language networks …

The Acute Effects Of Aerobic And Resistance Exercise On Cardiovascular Function And Arterial Stiffness, Hayleigh Elizabeth Raiff

Honors Theses

The cardiovascular system changes acutely to the stresses of exercise to support the increased metabolic demand of the working tissues. This is accomplished through the augmentation of several parameters including heart rate, blood pressure, and vascular tone such as arterial stiffness. Exercise training has been shown to elicit changes in arterial stiffness but the acute effects of exercise on arterial stiffness have not been thoroughly studied. The current study examined the acute effects of no (control), aerobic (30 minutes of cycling at ~70% maximum heart rate), and resistance exercise (30 minutes, 3 sets of 10 repetitions for 6 exercises) on …

Exercise Science Faculty Research and Publications

Individuals post stroke often rely more on hip flexors for limb advancement during walking due to distal weakness but the effects of muscle fatigue in this group is not known. The purpose of this study was to quantify how stroke affects the influence of hip flexor fatigue on over ground walking kinematics and performance and muscle activation. Ten individuals with chronic stroke and 10 without stroke (controls) participated in the study. Maximal walking speed, walking distance, muscle electromyograms (EMG), and lower extremity joint kinematics were compared before and after dynamic, submaximal fatiguing contractions of the hip flexors (30% maximal load) …

Gdnf Content And Nmj Plasticity In Slow And Fast Twitch Myofibers Follows Recruitment In Exercise, Amy Morrison Gyorkos

Dissertations

Glial cell-line derived neurotrophic factor (GDNF) supports and maintains the neuromuscular system during development and through adulthood by promoting neuroplasticity. GDNF may play a role in delaying the onset of aging and help compress morbidity by preventing motor unit degeneration. Exercise has been shown to alter GDNF expression differently in slow and fast twitch myofibers. The aim of this dissertation project is to determine if different intensities of exercise can promote changes in GDNF expression and neuromuscular junction (NMJ) morphology in slow and fast twitch muscle fibers. Skeletal muscle fibers were analyzed from adult Sprague Dawley rats aged 4 weeks …

The Effect Of Shear Stress, Potassium, And Adenosine On Α-1 Adrenergic Vasoconstriction Of Rat Soleus Feed Arteries, Tanner J. Heckle

Seaver College Research And Scholarly Achievement Symposium

During exercise, sympathetic nerve activity increases, augmenting the release of the neurotransmitter norepinephrine (NE) at the arterial wall and into the blood. NE binds to arterial adrenergic receptors to cause vasoconstriction, yet arteries in contracting skeletal muscle dilate during exercise. Previous evidence from Ives et al. suggests that heat and acidosis may partially inhibit constriction resulting from α-1 adrenergic receptors (termed sympatholysis). Our lab has previously demonstrated that rat soleus feed arteries respond to sympathetic signaling solely by α-1 adrenoceptors. We hypothesized that increased levels of arterial wall shear stress, potassium, or adenosine also contribute to sympatholysis, thereby reducing sympathetic …

Influence Of Athlete Heart Rate, Rate Of Perceived Exertion, And Anxiety In Rowing Practice And Competition, Katherine Skrlj Krengel

Master's Theses and Doctoral Dissertations

The purpose of this study was to investigate whether there is a significant correlation between heart rate (HR) and rate of perceived exertion (RPE) in rowing, how athlete perception of pre-race anxiety relates to HR and RPE, and how these variables change between practice and competition. Four subjects were tested over the course of their rowing season for somatic and cognitive anxiety, self-confidence, HR, and RPE in three different 2000 meter racing conditions: indoor ergometer, on-water racing, and on-water practice. There was no correlation between HR and RPE, and only maximum HR showed a difference between trial types. Studying more …

Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann

Industrial Technology and Packaging

With so many studies being conducted on professional football players regarding concussions and other related brain injuries, it’s amazing that such an important demographic has been missed. While NFL players are just as subjected to serious injuries as anyone else or even more so, it is important to remember that these players are outfitted, in most cases, with top-of-the-line equipment -- especially their helmets. If the focus is shifted to a younger demographic, youth football players in middle school and high school, the equipment is far less advanced and in a vast majority of cases, has been previously used by …

Delivery And Pitch Type Alter Ground Reaction Forces In Baseball Pitching, Garrett Kass

Featured Research

Ground reaction forces (GRFs) exerted on a pitcher in reaction to the push of their legs against the ground create torques about the center-of-mass (CM) and generate the angular momentum necessary to rotate the body, including the segments of the throwing arm. Thus examination of GRFs provides insight into the causal mechanisms responsible for segmental rotation in baseball pitching. PURPOSE: To determine the effects of delivery [wind-up (WU) vs. stretch (ST)] and pitch type [fastball (FB) vs. change-up (CU)] on GRFs in pitching. METHODS: Eight collegiate baseball pitchers (4 right-handed and 4 left-handed) provided voluntary informed consent and threw maximal …

Cardiac Rehabilitation Programmes For Low-Risk Patients And Leisure Athletes: A Potential Paradox, Wendy Bjerke, Stu Steinman, Vincent Cotto

All PTHMS Faculty Publications

Background: Athletes are enrolled in cardiac rehabilitation (CR) programmes in small numbers and require unique diagnostic testing and training considerations. Additionally, many physiotherapists, exercise physiologists, athletic trainers and physicians lack experience treating athletes in CR due to their limited exposure to these types of patients. Content: This analysis distinguishes athletes from typical CR patients within the context of diagnostic testing, assessment, exercise prescription, and management. Several case studies present unique challenges and approaches to the rehabilitation of athletes in a CR setting. Conclusions: Athletes enrolled in CR should be treated and trained according to their abilities and goals. Combining traditional …

Effects Of Body Armor And Load Carriage On Lower Limb Joint Movement, Huiju Park, Donna Branson, Adriana Petrova, Semra Peksoz, Carla Goad, Aric J. Warren, Bert Jacobson, Panagiotis Kamenidis

Journal of Human Performance in Extreme Environments

This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with an increase in weight implies decreased mobility by restricting the leg’s swing to propel the body forward. Increased ROM for pelvic tilt found with increased weight results from increased forward inclination suggesting an increased possibility for fatigue and musculoskeletal pain …

However, this paper aims to critically review the emerging contribution of physiological based literature linked to fast bowling in cricket and also highlight the current evidence related to simulated and competitive in-match performance. Furthermore, the review considers limitations with past research and possible avenues for future scientific investigation. It is clear with the advent of new applied mobile …

A Review Of Recent Perspectives On Biomechanical Risk Factors Associated With Anterior Cruciate Ligament Injury, Gerwyn Hughes

Kinesiology (Formerly Exercise and Sport Science)

There is considerable evidence to support a number of biomechanical risk factors associatiated with non-contact anterior cruciate ligament (ACL) injury. This paper aimed to review these biomechanical risk factors and highlight future directions relating to them. Current perspectives investigating trunk position and relationships between strength, muscle activity and biomechanics during landing/cutting highlight the importance of increasing hamstring muscle force during dynamic movements through altering strength, muscle activity, muscle length and contraction velocity. In particular, increased trunk flexion during landing/cutting and greater hamstring strength are likely to increase hamstring muscle force during landing and cutting which have been associated with reduced …
