Oxygen Consumption In Highly Skilled Baseball Pitchers, Jesse Clingman
Oxygen Consumption In Highly Skilled Baseball Pitchers, Jesse Clingman
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to describe the physiological demands of highly skilled baseball pitchers during pitching, along with pitch metrics. Three junior college and three professional (n = 6) baseball pitchers participated in this study. Participants completed a graded exercise test (GXT) to volitional exhaustion to determine maximal oxygen consumption (VO2 max) and estimated body fat percentage, height, and body mass were measured on day one of testing. Next, participants faced live batters on a baseball field while wearing a portable metabolic analyzer (Cosmed K5) to measure respiratory gases including oxygen consumption (VO2) and carbon dioxide produced (VCO2) …
Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez
Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez
CMC Senior Theses
Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …
Risperidone And Its Deconstructed Analogs: Functional Effects On The 5ht2ar, Sneha Shah
Risperidone And Its Deconstructed Analogs: Functional Effects On The 5ht2ar, Sneha Shah
Theses and Dissertations
G protein-coupled receptors (GPCRs) are seven-transmembrane domain receptors that sense extracellular signal and activate intracellular signaling pathways. The serotonin 5HT2A receptor (or 2AR) is one of the GPCRs coupled to Gq proteins, activating PLC and hydrolyzing PIP2. This hydrolysis causes a diffusion of bound PIP2 away from the channel binding site resulting in G protein-gated inwardly rectifying K+ channel (GIRK) inhibition and a downstream stimulation of Ca2+ release from endoplasmic reticulum stores. Previous experiments have demonstrated that the serotonin 5HTA receptor is a target of serotonergic psychedelic drugs, such as LSD, and partially mediates the action of many …
The Relationship Between Functional And Histological Changes In Muscle Following Eccentric Exercise In Mice, Michael John Newton
The Relationship Between Functional And Histological Changes In Muscle Following Eccentric Exercise In Mice, Michael John Newton
Theses: Doctorates and Masters
Exercise-induced muscle damage (EIMD) is known to be produced by novel or unaccustomed exercise, especially high force eccentric contractions. Histological myofibre disruption, force loss and muscle soreness are associated with EIMD and have implications for sporting performance. Traditional practices of assessing the extent of disruption to the myofibres is by performing needle biopsies and subsequently analysing the histology of the fibres. Recently there has been interest in investigating whether changes in force production and contractile properties of muscle following damaging exercise correlate strongly with the magnitude of disruption to the myofibres. The main aim of this study was to investigate …
