Mental Toughness, Servant Leadership, And The Collegiate Distance Runner, Christopher S. Hammer

EWU Masters Thesis Collection

"Mental toughness is commonly associated with successful performance in the realm of athletics. However, despite the prevalence of its usage, the concept remains somewhat ambiguous in its definition and practical application. The purpose of this study was to determine the relationship between mental toughness and running performance amongst collegiate distance runners, a population that has yet to be the center of a mental toughness investigation. Of additional interest was to determine how a coach's servant leadership attributes interacts with athletes' mental toughness. Participants (n = 334) were males and females from 64 collegiate track teams from all divisions of the …

Body Mass Bias In Exercise Physiology, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

In certain physically demanding occupations, especially the military, body mass bias has substantive implications. Work physiologists have determined that despite body mass bias in the common military physical fitness tests, the larger service members were often better performers of the physically demanding occupational tasks (Bilzon et al., 2002; Lyons et al., 2005; Rayson et al., 2000). That is, they could carry more, more easily evacuate casualties, and better engage in heavy materiel handling. Yet, the smaller personnel were achieving better scores on the physical fitness tests, the results of which have significant promotion and advancement implications (Vanderburgh & Mahar , …

Leadership By Design Summer Day Camp: University And High School Student Outcomes, Mary F. Fortune, Mark F. Roark, Mary D'Alleva, Lisa Smusz

Kinesiology and Health Science Faculty Publications

The Leadership by Design (LbD) summer day camp provided interactive learning experiences for university and high school students. While LbD is similar to other university recruitment programs, none looks directly at the learning outcomes for students through a social constructivist theory design that evaluates the acquisition of the learning outcomes. With such a design, the summer day camp offered leadership development opportunities to university students through a “live,” hands-on experience in a special event management course curriculum. LbD also provided high school participants with an opportunity to explore leadership characteristics and increase their understanding of university culture. The specific purpose …

Does Endurance Training Alter Energy Balance?, Brittany Inlow

LSU Master's Theses

An examination of the effects of a structured activity program on resting metabolic rate (RMR), physical activity, and dietary behavior is essential in gaining a better understanding of potential strategies that may be used in future exercise training programs. PURPOSE: To explore whether endurance training alters energy balance via changes in resting metabolic rate (RMR), daily energy expenditure (EE) and energy intake (EI). METHODS: Twenty-four subjects (17 females, 7 males; 21 + 0.3 years old) were assigned to one of two groups: 1) endurance (E; n = 12), or 2) active control (AC; n = 12). The E group completed …

A Systematic Review Of Physical Activity Interventions In Hispanic Adults, Melinda J. Ickes, Manoj Sharma

Kinesiology and Health Promotion Faculty Publications

Healthy People 2020 aims to achieve health equity, eliminate disparities, and improve the health of all groups. Regular physical activity (PA) improves overall health and fitness and has the capability to reduce risk for chronic diseases. Identifying barriers which relate to the Hispanic population is important when designing PA interventions. Therefore, the purpose was to review existing PA interventions targeting Hispanic adults published between 1988 and 2011. This paper was limited to interventions which included more than 35% Hispanic adults (n = 20). Most of the interventions were community based (n = 16), although clinical, family-based, and faith-based …

Plantar Vibrotactile Detection Deficits In Adults With Chronic Ankle Instability, Matthew C. Hoch, Patrick O. Mckeon, Richard D. Andreatta

Human Movement Studies & Special Education Faculty Publications

Purpose: The purpose of this study was to investigate the vibrotactile detection thresholds of the plantar cutaneous afferents in subjects with chronic ankle instability compared with healthy control subjects. Methods: Eight adults with chronic ankle instability and eight adults with no ankle sprain history participated. Vibrotactile detection thresholds were assessed using a mechanical stimulus generator system, mounted onto an articulated microscope arm, which delivered sinusoidal vibrotactile inputs to the foot sole at three different sites: head of the first metatarsal, base of the fifth metatarsal, and the heel. Vibrotactile stimulation was delivered at a range of test frequencies that corresponded …

Physical Activity: The Forgotten Tool For Type 2 Diabetes Management, Sheri R. Colberg

Human Movement Studies & Special Education Faculty Publications

Individuals who are currently sedentary, unfit, or overweight can benefit metabolically from simply taking breaks from sitting. Since avoidance of sedentary behavior appears to have a large impact on glycemic management, all individuals with type 2 diabetes should be encouraged to minimally engage in greater daily movement to better manage their diabetes and body weight. In addition, engaging in physical activity of any intensity (including low-intensity ones) likely positively impacts insulin action and blood glucose control acutely. Moreover, as long as total caloric expenditure during exercise is matched (i.e., total exercise dose), daily exercise may be done every other day …

Autonomic Nervous System Response To Repeated Cold Exposure, Jonathan A. Simmons

LSU Master's Theses

Recent work suggests repeated cold exposure raises energy expenditure, partly due to sympathetic nervous system stimulation, which indicates repeated cold exposure as a possible strategy to combat obesity without significant behavioral changes. PURPOSE: (1) To examine the acute resting metabolic rate (RMR) response to mild cold exposure of 16° C and the acute autonomic nervous system (ANS) response to two cold exposures of 16° C and 4° C through heart rate variability (HRV) indices; and (2) to examine whether 4 weeks of daily cold exposure would result in adaptations in the metabolic and autonomic responses to acute cold exposure. METHODS: …

Vitamin D Status, Adiposity, And Athletic Performance Measures In College-Aged Students, Laura Forney

LSU Master's Theses

Research suggests that elevated serum concentrations of 25-hydroxyvitamin D (25OHD) are associated with slowing the development of many age-related chronic diseases. Recent reports also show a positive relationship between 25OHD and muscle synthesis, strength, power and decreased body fat in elderly individuals. However, these findings have not been consistently reported in younger, healthy populations. PURPOSE: To investigate the relationship between 25OHD levels, body composition, measures of aerobic fitness and muscular strength and power in a young, physically active population. METHODS: Thirty-nine active subjects (20 males, 19 females; 23 ± 0.7 years old) reported to the lab six times for testing. …

The Biomechanics Of Tongue Projection In The Frog _Rana Pipiens_: Dynamics And Temperature Effects, Paula Sandusky

USF Tampa Graduate Theses and Dissertations

Ectotherms such as frogs must either function within environments with temperatures amenable to their physiological needs, or find means to reduce the impact of temperature on their activities. Recent studies on reptile and amphibian feeding have shown convergent use of elastic recoil to drive feeding movements, thereby decoupling temperature's effects on muscle from movement and allowing the animals to feed over broader temperature ranges. Rana pipiens specimens (n=5) were exposed to three ambient temperatures (10°, 15°, and 25° C) at which feeding behavior was imaged at 6000 Hz. The image sequences yielded detailed kinematic and dynamic information for jaw, tongue, …

METHODS: 24 healthy college age subjects (14 female, 10 male, age 19-30) completed four trials using a randomized crossover design. Trials consisted of assessing the maximal voluntary isotonic contraction (MVC) and pennation angle (PA) before and after each treatment. Treatments consisted of either stretching (S) or mock stretching (MS). The S treatment involved four 30 second periods of stretching with 15 seconds of rest in between. During the MS treatment subjects were maintained in the …

Optimizing Chronic Slow Breathing Training To Cause A Therapeutic Effect On Heart Rate Variability, Jennifer Joy Brown

Human Movement Studies & Special Education Theses & Dissertations

Heart rate variability (HRV) is a valid and reliable tool that can be used to determine the basic state of an individual's autonomic health. The current study attempted to establish the minimum frequency of breathing practice necessary to produce a therapeutic effect on HRV over the course of a four-week period with four different treatment groups, specifically, groups that practiced a slow breathing protocol for either 2, 3 or 5 times per week, and a control group. Forty-three subjects (14 males, 29 females), ages 18–50 years, were screened, pre-tested, matched for sex, age and HRV, assigned to a specific group …

Variability Of Gait Is Dependent On Direction Of Progression: Implications For Active Control, Shane R. Wurdeman, Neil B. Huben

Journal Articles

Typical healthy walking displays greater variability in the mediolateral direction compared to the anteroposterior direction. This greater variability is thought to represent increased uncertainty in movement. As a result, it has been postulated that the mediolateral direction of gait requires more active control by the central nervous system while the anteroposterior direction is controlled through passive actions. However, this theory has only been tested on gait where progression occurs in the anteroposterior direction. Therefore, the purpose of this study was to investigate how the amount of variability is affected if progression occurs in the mediolateral direction using a lateral stepping …

Estimates Of Critical Power And Anaerobic Work Capacity From A Single, All-Out Test Of Less Than 3-Min, H C. Bergstrom, T J. Housh, Jorge M. Zuniga, C L. Camic, D A. Traylor, R W. Lewis, R J. Schmidt, G O. Johnson

Journal Articles

The purpose of this study was to determine if Critical Power (CP) and Anaerobic Work Capacity (AWC) could be estimated from a single, all-out test of less than 3-min. Twenty-eight subjects (mean ± SD: age 23.3 ± 3.3 years, body mass 71.6 ± 16 kg) performed an incremental cycle ergometer test to exhaustion to determine peak oxygen consumption rate and heart rate peak. The 3-min all-out test was used to determine the criterion and six estimated values of CP and AWC. The criterion critical power (CP180) and anaerobic work capacity (AWC180) values were determined from the 3-min all-out test and …

Social Identity Theory In Campus Recreation: Examining Organizational And Exercise Identification Among Recreation Center Users, Kiel Emberton

Masters Theses

Social identity theory is often used in commercial settings to provide a basis for psychographic market segmentation. This usage has led to the development of organization identification in traditional business settings. Campus recreation is unique in that the primary product of consumption is exercise. In describing exercise behavior, social identity theory has been applied to explain the unique psychological attachments exercisers have to their exercise behavior. This application of social identity theory created the exercise identity construct. The purpose of this study was to examine social identity theory in campus recreation. Specifically, this study investigated the correlation between frequency of …

Kinematic Analysis Of Four Plyometric Push-Up Variations, Laura H. Moore, Michael J. Tankovich, Bryan L. Riemann, George J. Davies

Health Sciences & Kinesiology: Faculty Publications

Plyometric research in the upper extremity is limited, with the effects of open-chain plyometric exercises being studied most. Kinematic and ground reaction force data concerning closed-chain upper extremity plyometrics has yet to be examined. Twenty-one recreationally active male subjects performed four variations of plyometric push-ups in a counterbalanced order. These included box drop push-ups from 3.8 cm, 7.6 cm, 11.4 cm heights, and clap push-ups. Kinematics of the trunk, dominant extremity and both hands were collected to examine peak flight, elbow flexion at ground contact, elbow displacement, and hand separation. Additionally peak vertical ground reaction force was measured under the …

"The purpose of this study was to compare RPE between ATM and SWW at 50%, 60%, and 70% HRR in a healthy adult population. Fifteen subjects (7 male, 8 female) performed both ATM and SWW at each pre-determined % HRR for a total of four days. The participants attended two familiarization sessions in which they practiced protocol and were taught the RPE scale. Each participant was scheduled for two testing sessions (one for the ATM and one for SWW) after the familiarization where they conducted the testing protocol of two minutes steady-state HR at each personalized % HRR. Within the …

The Effects Of Seat Post Angle In Cycling Performance, Saori Hanaki-Martin

Theses and Dissertations--Kinesiology and Health Promotion

Triathlon involves three different modes of endurance events, swim, bike and run, consecutively. Transitions between events are critical to be successful in the sport; however, many triathletes report impaired running performance due to adverse residual effects from cycling. One of the strategies that triathletes use to manage the adverse effects is to use a bicycle with a more vertical seat post angle. There is limited evidence that support the effectiveness of such bicycle geometry, but many of these studies lacks ecological validity.

Twelve triathletes and cyclists completed a 20-km simulated course with instrumentations for 3D motion, kinetic, and electromyographic analyses …
