Zebrafish As A Model To Understand The Impact Of Inactivity And Neuromuscular Electrical Stimulation On Duchenne Muscular Dystrophy, Elisabeth Kilroy
Zebrafish As A Model To Understand The Impact Of Inactivity And Neuromuscular Electrical Stimulation On Duchenne Muscular Dystrophy, Elisabeth Kilroy
Electronic Theses and Dissertations
Skeletal muscle plasticity is imperative for functional adaptation to changing demands in activity. Although a great deal is known about the structural and functional plasticity of healthy skeletal muscle, far less is known about plasticity in diseased muscle. Here, we combined the power of the zebrafish model with the adaptability of neuromuscular electrical stimulation (NMES) to study the basic mechanisms of plasticity in the zebrafish model of Duchenne Muscular Dystrophy (DMD). Four NMES paradigms, defined by their frequency, delay, and voltage, were designed to emulate the repetition and load schemes of human resistance training programs. Additionally, two inactivity paradigms were …
Bilateral Muscle Oxygenation Kinetics In Response To Repeat Sprint Cycling In Strong And Weak Individuals, John Abbott
Bilateral Muscle Oxygenation Kinetics In Response To Repeat Sprint Cycling In Strong And Weak Individuals, John Abbott
Electronic Theses and Dissertations
Repeat sprint ability has been investigated thoroughly, however optimal training methodology to improve RSA remains elusive. Both kinetic and physiological viewpoints have been used to scrutinize aspects of RSA including, initial sprint performance (anaerobic power), maximal cardiorespiratory fitness (VO2max), lactate threshold, anaerobic capacity (mean power), muscle activation (EMG), and local muscle oxygenation kinetics. To our knowledge no study has utilized maximal strength levels as a separate factor among a homogenous group of cardiorespiratory fitness individuals (as determined by peak VO2 during RSA). The purpose of this study was to better understand the relationship between maximal strength, muscular characteristics, and cycling …

Compensatory Inactivity In Female Collegiate Soccer Players, Caylee Costello
Electronic Theses and Dissertations
Objective: To measure the physical activity levels of Division I collegiate female soccer players with the use of accelerometers to help determine compensatory changes and help establish appropriate training rhythms through the course of a season.
Design: 25 female Division I soccer players volunteered to participate in a 7-day observational study. Players wore an ActiGraph GT3X+ accelerometer during waking hours. Five second epochs were recorded and age appropriate physical activity cut points were used to determine the minutes of sedentary time (ST), light physical activity (LPA), moderate physical activity (MPA), vigorous physical activity (VPA) and moderate to vigorous physical activity …
