The Relationship Between Subjectively Motivational Music And Various Exercise Variables While Running At Maximal Speed, Michael Maloney

Honors College Theses

Purpose: To determine whether there are differences in steps/min/m, highest achieved exercise heart rate, average exercise heart rate, average running speed, estimated relative VO2, and RPE, while listening to subjectively motivating music, as compared to non-motivating music, while running at max speed. Methods: Eleven students enrolled at the University of Massachusetts Boston, considered “non-runners” from 19 to 34 years of age, ran at max speeds for 12-15 minutes, once while listening to a play-list of songs they ranked most motivating, and a second time on a separate day, while listening to a play-list of songs they ranked least …

Arterial Adaptations To Training Among First Time Marathoners, Nicole Hafner

Masters Theses, 2010-2019

Increased arterial wall thickness has been positively related to cardiovascular disease. Exercise has been found to favorably alter arterial anatomy in the trained limbs, but its effects on untrained limbs and the carotid artery are unclear. Thus, brachial (non-trained limb), popliteal (trained limb) and carotid, wall thickness (WT), wall to lumen diameter ratios (W:L), intima-media thickness (IMT) and lumen diameters (LD) were compared between recreationally active (n=14) and untrained (n=11) subjects before and after, the active subjects participated in 12 weeks of marathon run training. Arterial dimensions were measured with B-mode ultrasonography. Pre and post-training VO2max and running speed at …

Effects Of Foot Type On Multi-Segment Foot Motion In High- And Low-Arched Female Recreational Athletes, Douglas W. Powell

Doctoral Dissertations

Introduction: Mal-alignment and dysfunction of the foot have been shown to result in an increased rate of injury and unique injury patterns. Aberrant foot function has been shown to contribute to repetitive stress and acute injuries. High-arched athletes have been shown to experience a greater rate of bony injury to the lateral aspect of the lower extremity while low-arched athletes experience greater rates of soft-tissue injury to the medial aspect of the lower extremity. Though foot type has been linked to these injury patterns, the mechanism by which these injury patterns occur remains unknown. Multi-segment foot models have been developed …

Effects Of Footstrike Pattern On Low Back Posture, Shock Attenuation, And Comfort During Running, Traci L. Delgado, Emilia Kubera-Shelton, Robert R. Robb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Barefoot running (BF) is popular in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). In addition, changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain (LBP). However it is not known how changing from RFS to FFS affects lumbar lordosis or LBP. Thus, the purpose of this study was to determine if a change from RFS to FFS would change lumbar lordosis, and/or decrease shock attenuation, and/or change comfort levels in healthy recreational/experienced runners.

Methods: …

Effect Of Step Rate On Foot Strike Pattern And Running Economy In Novice Runners, Janae Lynn Richardson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose—The objective was to examine if step rates ±5% or ±10% of a novice runner's preferred step rate (SR) is sufficient enough to shift a novice runner’s foot strike pattern (FSP) (rear-foot, mid-foot, forefoot) and whether these SR changes produce changes in the rate of submaximal oxygen consumption (VO2). Methods—Foot strike angle (FSA) was recorded using sagittal plane video images and VO2 was measured for novice runners while running on a treadmill at a constant speed during increased and decreased (±5% and ±10%) SR conditions. Foot strike angle was used to predict strike index (SI) (predicted strike index = [FSA …

The Effect Of Exertion On Intra-Limb Joint Coordination Variability During Running Using A Waveform Analysis Approach, Lauren Benson

Theses and Dissertations

About half of all runners sustain a running-related injury in a given year. Less variable joint coordination patterns may be detrimental as stress endured by the same tissue, encountered over many running cycles, could lead to overuse running injuries. The effects of fatigue may contribute to runners' risk of injury by altering joint coordination variability. Since fatigue is task-dependent, it is practical to consider a level of fatigue typically experienced by runners. The purpose of this study was to examine the influence of running in an exerted state on lower extremity joint coordination variability, using Principal Components Analysis (PCA) and …

The Effects Of Arch Taping On Shock Attenuation During Landing, Shun Jinnouchi

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to investigate the effects of two different arch taping techniques on shock attenuation during landing. Each subject (n=12, age 25.5 ± 3.37 years, height 1.73 ± 0.04 m, mass 82.06 ± 16.23) was instrumented with accelerometers at the leg and forehead (sample rate = 1000 Hz). Subjects performed landings from a 30 cm box under three taping conditions: no tape, Low Dye, and Weave. For each condition, subjects completed 5 landing trials. Rest was provided between each trial and order of conditions was counterbalanced. During each landing, accelerations were recorded at 1000 Hz for …

Effect Of Racing Flats On Running Economy In Male Adolescent Runners, Paul Hafen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to investigate whether running economy differs in racing flats versus standard running shoes in high school cross-country runners. In order to measure running economy the oxygen cost of running (mL O₂∙kg^-1∙min^-1) was measured in 20 male adolescent runners (mean age = 16.25 ± 0.97 years, 5 km best time = 17.52 ± 0.78 min) when running two separate trials at a controlled speed. The speed was determined by estimating treadmill running speed at 85% of each runner's VO_2max. Each trial required the participants to run while …

The Effects Of Insoles On Loading Rate In Level Running, Crystal Ruano, Douglas Powell, Doug Renshaw, Elizabeth Chalambaga, Matthew Bice

Doug Renshaw

Introduction: Running is one of the most popular recreational sports in America with over 250 million regular runners. Recreational and competitive runners often experience over-use injuries including plantar fasciitis, Achilles tendinitis and stress fractures. Previous research has shown that the transmission of ground reaction force through the lower extremity leads to these over-use injuries; however, it is not solely the magnitude of vertical ground reaction forces, but also the rate at which these forces are applied that may lead to lower extremity injury. Many recreational runners will use over-the-counter insoles as a method of treating an injury or as a …

Effect Of Gps Feedback On Lactate Threshold Pacing In Intercollegiate Distance Runners, Jacob W. Smith, Matthew F. Moran, John T. Foley

International Journal of Exercise Science

International Journal of Exercise Science 6(1) : 74-80, 2013. In their roles as coaches, the authors have observed that first-year collegiate distance runners often have difficulty running at prescribed training paces during lactate threshold (LT) training runs. Previous research has validated the accuracy of global positioning system (GPS) devices in providing distance and velocity feedback during running. The purpose of this study was to determine the efficacy of using the Garmin Forerunner 305 GPS watch (Garmin) to reduce deviations from prescribed training paces during LT runs with first-year collegiate runners. Participants were two groups of varsity cross country runners who …

Variations In Running Technique Between Female Sprinters, Middle, And Distance Runners, Ruthann Cunningham, Iain Hunter, Matthew K. Seeley, Brent Feland

International Journal of Exercise Science

International Journal of Exercise Science 6(1) : 43-51, 2013. In the sport of track and field, runners excel not only due to physiological characteristics but also aspects in running technique. Optimal technique allows runners the perfect the balance between running speed and economy. The ideal movement pattern may vary between events as the goal goes from economy of movement in the long-distance events to speed and power in the sprints. Understanding how each type of runner moves differently will help coaches more effectively train their athletes for each specific running event. This study was conducted to determine if sprinters, middle-distance, …
