Characterization And Reliability Of The Work-Time Relationship During Arm-Cranking, Tristan Starling-Smith
Characterization And Reliability Of The Work-Time Relationship During Arm-Cranking, Tristan Starling-Smith
Electronic Theses and Dissertations, 2020-
INTRODUCTION: The critical power (CP) exercise test provides 2 measures, CP and anaerobic working capacity (AWC). CP represents a fatigue threshold that separates the heavy and severe exercise domains, while AWC represents the finite amount of work that can be done above CP. A relatively new protocol for estimating CP has emerged and is described as the 3-minute all-out test (3MT). While this lower body 3MT test has been examined for validity and reliability, very little has been done for the upper body. PURPOSE: Examine the reliability of EP and WEP from the 3MT during upper-body ergometry. This study also …
Utility Of Novel Rotational Load-Velocity Profiling Methods In Collegiate Softball Players, Chad Herring
Utility Of Novel Rotational Load-Velocity Profiling Methods In Collegiate Softball Players, Chad Herring
Electronic Theses and Dissertations, 2020-
The purposes of this study were to determine the reliability of the bat swing (BS) and rotational medicine ball throw (RMBT) load-velocity profiling (LVP) methods and the relationships between LVP variables and batting performance in NCAA Division I softball players. Current NCAA Division I softball athletes participated in this study. Bat velocity was tracked with a swing sensor during the BS method. An inertial measurement unit (IMU) tracked forearm velocity during the BS and RMBT methods. Two-way intraclass correlation coefficients (ICC) were used for relative reliability and coefficient of variation (CV) was used for absolute reliability. For the BS method …
Contextualizing The Acute Responses To Arm Cycling, Nicolas Clark
Contextualizing The Acute Responses To Arm Cycling, Nicolas Clark
Electronic Theses and Dissertations, 2020-
The prescription of aerobic exercise modalities engaging the arm musculature have the potential to extend the reach of physical activity and promote cardiorespiratory fitness in individuals with lower body impairment due to excessive body mass, and among individuals seeking to complement and diversify standard leg training. This study compared the acute cardiopulmonary responses obtained during arm cycling and leg cycling performed at different intensities among lean and average (LA) and overfat and obese individuals (OFO). Participants were 37 young and relatively healthy adults. They were tested for mode-specific peak power output and work rate at ventilatory threshold during two randomized …
Influence Of Body Composition, Velocity Profiles, And Sex-Related Differences On Army Combat Fitness Test Performance, David Boffey
Influence Of Body Composition, Velocity Profiles, And Sex-Related Differences On Army Combat Fitness Test Performance, David Boffey
Electronic Theses and Dissertations, 2020-
The Army Combat Fitness Test (ACFT) will become the United States Army's mandatory physical fitness test in March of 2022. The purpose of this study was to determine the relationship between ACFT performance and both body composition and velocity profiles, and to determine sex differences for these variables. Data was collected in November 2020 (Fall) and March 2021 (Spring) from male (n = 55) and female (n = 17) Army Reserve Officers' Training Corps (ROTC) cadets. Body composition was assessed with a bioelectrical impedance spectroscopy (BIS) device, and cadets completed a squat jump (SJ) force-velocity profile (FVP) and a hex …
