Evaluating A Current Athlete Assessment Program, David Fish May 2024

Evaluating A Current Athlete Assessment Program, David Fish

Electronic Theses and Dissertations

The primary purpose of this dissertation is to evaluate the effectiveness of a questionnaire designed to assess coaches’ perceptions of an athlete monitoring program. There are four reasons for this examination of perceptions: 1) it may serve as a check for understanding of how the coach takes in the information presented to them, 2) identify any gaps in the knowledge of the coach which the sport scientist may help to fill, 3) can serve to open a dialog with the coach for ways in which the information may be better tailored to help them improve their decision-making, and 4) the …

The Immediate Effects Of Dry Cupping The Lumbar Paraspinals On Range Of Motion And Temperature, Natasha Scavarelli, Paolo Sanzo Apr 2024

The Immediate Effects Of Dry Cupping The Lumbar Paraspinals On Range Of Motion And Temperature, Natasha Scavarelli, Paolo Sanzo

International Journal of Exercise Science

International Journal of Exercise Science 17(3): 551-564, 2024. Dry cupping is a therapeutic modality proposed to produce a negative pressure, stretching the skin and underlying tissue. This mechanism is said to promote regional blood flow of oxygenated blood and causing a physiological stretch in the tissue, allowing it to elongate and potentially changing skin temperature. The possible effects of the application to the lumbar spine paraspinal muscles, however, has not been thoroughly examined. The purpose of this pilot study was to explore the immediate effects of dry cupping the lumbar paraspinals on lumbar spine range of motion (ROM) and overlying …

International Journal of Exercise Science

International Journal of Exercise Science 17(4): 429-437, 2024. The Army Combat Fitness Test (ACFT) is a newly developed test that assesses the combat readiness of U.S. Army soldiers. The purpose of this cross-sectional study is to determine if VO2max can predict performance outcomes of the ACFT in ROTC cadets. This understanding can provide a better understanding of the aerobic demands of the ACFT. Cadets (50 males, 14 females; aged 21.43 ± 4.10 years) completed the 6-event ACFT (maximum trap-bar deadlift [MDL], standing power throw [SPT], hand-release pushups [HRPU], sprint-drag-carry shuttle run [SDC], plank [PLK], and 2-mile run [2MR]). The …

Flexible Phenotypes, Energetics, And Whole-Animal Performance Of Migratory Songbirds, Michael Griego Oct 2022

Flexible Phenotypes, Energetics, And Whole-Animal Performance Of Migratory Songbirds, Michael Griego

Doctoral Dissertations

Animal life has evolved innumerable strategies to adapt to a great range of environmental conditions present on earth. The physiology of free-living animals has thus been shaped to allow for maximal performance under challenging conditions and has given rise to traits that enable animals to overcome daunting ecological pressures. Few life history stages in the animal kingdom rival the intensity of annual avian migration: the extreme metabolic requirements of long-distance flight coupled with navigating vast and hostile ecological barriers results in enormously high mortality for young birds. It is therefore the main focus of this thesis to identify physiological traits …

Acute Ingestion Of A Commercially Available Pre-Workout Supplement Improves Anaerobic Power Output And Reduces Muscular Fatigue, Sotiris Panayi, Andy Galbraith

International Journal of Exercise Science

International Journal of Exercise Science 15(6): 455-472, 2022. The effect of a pre-workout supplement on anaerobic power output and muscular fatigue was examined. 18 participants took part in this double-blinded crossover study, reporting for testing on 3 occasions. Participants completed a 6x6 second repeated sprint test, with 20s recovery between sprints. Anaerobic power output was recorded as the highest power achieved during sprint test. Muscular fatigue was reported as a fatigue index across the six sprints ((maximum power – minimum power) ÷ total sprint time). During a baseline visit, participants consumed 250ml of water 30 minutes prior to testing, whilst …

Evaluation Of Air Consumption And Work Efficiency In Structural Firefighters, Emily Lynn Langford Jan 2022

Evaluation Of Air Consumption And Work Efficiency In Structural Firefighters, Emily Lynn Langford

Theses and Dissertations--Kinesiology and Health Promotion

INTRODUCTION: For safe and efficient fireground performance, firefighters (FF) must consume air supplied by the self-contained breathing apparatus (SCBA) efficiently while sustaining high work rates. Firefighter research and fire department physical ability assessments typically quantify performance solely on task completion time (i.e., work rate), failing to consider the critical element of air consumption efficiency, which subsequently impacts the SCBA’s functional work duration. PURPOSES: (Arm 1, Aim #1) To examine variability in air consumption (AC) between FF during standardized pace tasks; (Arm 1, Aim #2) To evaluate AC efficiency (ACE) against a recognized metabolic-work rate concept of economy; (Arm …

The Effects Of Concurrent Activation Potentiation On Bat Swing Velocity Of Division Ii College Softball Athletes, Alexis Mace, Charles Allen Oct 2020

The Effects Of Concurrent Activation Potentiation On Bat Swing Velocity Of Division Ii College Softball Athletes, Alexis Mace, Charles Allen

International Journal of Exercise Science

International Journal of Exercise Science 13(1): 1630-1637, 2020. As an ethical and practical ergogenic strategy, concurrent activation potentiation (CAP), achieved by remote voluntary contractions (RVC) such as jaw clenching, has been proposed to acutely enhance muscular and athletic performance characteristics. The effects of CAP on bat swing velocity (BSV), an important component for successful hitting in sports such as baseball and softball has yet to be reported in the literature. The purpose of this research was to examine the effects of maximal jaw clenching on BSV in collegiate division II softball players. Thirteen (n = 13) division II softball …

Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko Jun 2019

Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko

Electronic Theses, Projects, and Dissertations

Aging in skeletal muscle is characterized by a loss in muscular performance. This is in part related to the direct loss of muscle mass due to senescence, known as sarcopenia. With age, skeletal muscles lose force production, contractile speed, and power production. The force velocity relationship of muscle is a product of force production and contraction speed, both of which decline with age; however, the mechanisms and trajectory of this decline are not well understood. Exercise has positive effects on muscle, and thus may assist in maintaining performance in old age. However, few long-term studies have been performed to examine …

International Journal of Exercise Science

International Journal of Exercise Science 12(3): 904-918, 2019. Functional Fitness Training (FFT) programs are characterized by utilizing a high volume of training and using a variety of high intensity exercises. While FFT are growing in the number of practitioners and popularity, the relationship between physiological biomarkers and subjective scales in the specific context of FFT has not yet been evaluated in the literature. The purpose of the present study was to monitor the time-course response of cytokines (IL-10 and 1L-1b), immune variables (C-reactive protein -CRP and immunoglobulin A-IgA), hormonal milieu (cortisol-C, total testosterone-TT, free testosterone-FT and testosterone/cortisol-T/C ratio), creatine kinase-CK, …

Breathing Limited Air Situational Training Masks (Blastmask) Versus Self-Contained Breathing Apparatus (Scba) For Firefighters: A Pilot Study, Thomas Andre, Silvio Valladao, Shana Walsh, Derek Reisbeck

International Journal of Exercise Science

International Journal of Exercise Science 12(6): 941-949, 2019. Despite maintaining high levels of fitness, firefighters’ performance may be negatively impacted by the use of a Self-Contained Breathing Apparatus (SCBA), an essential piece of safety equipment worn during structural firefighting. Routine training with SCBAs can be cost-prohibitive and inefficient. The Breathing Limited Air Situational Training Mask (BlastMask) was developed as a training aid used to simulate the SCBA. The purpose of this study was to examine physiological and perceptual responses elicited by firefighters during steady state exercise when using the BlastMask compared to the SCBA. Current staff male firefighters (n …
