Borg Scale Is Valid For Ratings Of Perceived Exertion For Individuals With Parkinson’S Disease, Amanda Penko

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 76-86, 2017. Parkinson’s disease is a neurodegenerative disease that has traditionally been treated with anti-parkinsonian medication. There is increasing evidence that exercise is beneficial to those with PD, therefore, it is necessary to validate a measure of exertion that can be implemented across exercise settings that may not have the capability to actively monitor heart rate. The aim of this project was to determine the validity of the Borg RPE scale in individuals with PD undergoing a maximal progressive cycling exercise test. Thirty-eight males and females (58.5 ± 8.1 yrs) with a clinical diagnosis …

Assessing Energy Level As A Marker Of Aerobic Exercise Readiness: A Pilot Investigation, Kelley Strohacker, William R. Boyer, Kayla N. Smitherman, Emily Cornelius, Daniel Fazzino

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 62-75, 2017. Energy ratings have been used as a marker of exercise readiness (i.e. pre-exercise physical/mental state indicating ability to perform) within flexible nonlinear periodization (FNLP)-based resistance training interventions. However, empirical data is lacking regarding the utility of this approach for aerobic exercise. The purpose of this study was to examine the ability of pre-exercise energy level to predict affective and behavioral responses to prescribed aerobic exercise. Participants consisted of 19 women and 8 men (N=27, age=20±4 years, estimated maximal oxygen uptake=37±6). Participants performed two 30-min bouts of treadmill exercise under an imposed moderate …

The Acute Effects Of Static Stretching Compared To Dynamic Stretching With And Without An Active Warm Up On Anaerobic Performance, Bradley J. Kendall

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 53-61, 2017. The Wingate Anaerobic Test (WAnT) has been used in many studies to determine anaerobic performance. However, there has been poor reporting of warm-up protocols and limited consistency between warm-up methods that have been used. With the WAnT being such a commonly-used test, consistency in warm-up methods is essential in order to compare results across studies. Therefore, this study was designed to compare how static stretching, dynamic stretching, and an active warm-up affect WAnT performance. Ten recreationally active participants (5 males, 5 females) with a mean (SD) age of 23.3 (0.7) volunteered for …

The Relationship Between Sports Specialization And Mental Toughness, Courtney Buhrow, Jacob Digmann, Jennifer J. Waldron

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 44-52, 2017. The pros and cons of early sport specialization compared to diversification have been examined in many research studies. The purpose of this study was to determine (a) the relationship between mental toughness and age of specialization in sport, and (b) differences in mental toughness based on early specialization of sport and gender. College athletes (N = 102) completed surveys about specialization and mental toughness, including MeBTough. The mean age of specialization was 13.45 (± 4.47). Results showed no significant difference in mental toughness of those who specialized early and those who did …

The Effect Of Military Load Carriage On Postural Sway, Forward Trunk Lean, And Pelvic Girdle Motion, Eileen M. Strube, Andrea Sumner, Roger O. Kollock Jr, Kenneth E. Games, Marie A. Lackamp, Masahiro Mizutani, Joellen M. Sefton

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 25-36, 2017. Musculoskeletal injuries are a common occurrence in military service members. It is believed that the load carried by the service member impedes stability and alters back and pelvis kinematics, increasing their susceptibility to musculoskeletal injuries, specifically in the lower extremities. The purpose of this study was to examine the effects of two different loads on postural sway, forward trunk lean, and pelvic girdle motion in United States Army Cadets. Twenty male Army Reserve Officers’ Training Corps Cadets participated in this study. Each participant performed the Modified Clinical Testing of Sensory Interaction (mCTSIB) …

Sport Commitment Among Adult Recreational Soccer Players: Test Of An Expanded Model, Amanda L. Frayeh, Beth Lewis

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 4-24, 2017. Adult sport leagues provide opportunities for physical activity (PA), but little is known about adults’ commitment to recreational sports. We proposed two expanded versions of Scanlan and colleagues’ sport commitment model (SCM) to explore psychosocial factors related to adults’ participation in these leagues. Model 1 proposed athletic identity and social cohesion as additional predictors of commitment. Previous research found these variables to be positively related to commitment, but had not systematically examined them within the context of the SCM. We also explored participation in moderate-to-vigorous physical activity (MVPA) as a behavioral manifestation …

The Validity Of Height As A Determinant Of Takeoff Distance To Hurdle One In Ncaa Division Iii Hurdlers 2017, Phillip Wiltshire

Master's Theses

The purpose of this study was to determine if the relationships between the height of a hurdler and the takeoff distance to the first hurdle for men and women as reported by Frye (2008) were valid for NCAA Division III 100 m and 110 m hurdlers. With no specific research reported to validate Frye’s data, it is unclear how the suggested takeoff distances were developed. It is also unclear whether hurdler height or another factor is the main determinant of takeoff distance for the high hurdlers. Participants in this study were three female 100 m hurdlers and four male 110 …

Cardiovascular Risk, Remote Ischemic Postconditioning, And Endothelial Ischemia-Reperfusion Injury, Brian A. Hemenway

Electronic Theses and Dissertations

Remote ischemic postconditioning (rIpost) is a potent vasculoprotective stimulus that is thought to reduce reperfusion injury associated with heart disease. However, certain animal models of cardiometabolic risk factors such as dyslipidemia, diabetes, and hypertension suggest the beneficial effects of rIpost to lessen reperfusion injury may be diminished. These findings have not been studied in clinically relevant humans. The aim of this study was to determine whether the protective effects of rIpost are reduced in the context of raised cardiometabolic risk in humans. Seven participants with raised cardiometabolic risk burden (age:57±7 years; BMI: 31±4kgm²participated in this 2X2 randomized cross-over …

The Effects Of Limb Dominance On Cross-Education In A Four Week Resistance Training Program, Caitlin Wend

Masters Theses

Cross-education is known as the phenomenon of strength transfer from the trained side of the body to the untrained side of the body by unilateral resistance training. Research has shown that limb dominance has an effect on the amount of strength that is gained on the untrained side. Studies have found that there is a greater cross over effect in strength from the dominant side of the body to the non-dominant side of the body than vice versa. The present study examined this effect by taking 12 college females and splitting them into three groups: dominant training, non-dominant training, and …

Vitamin D Status And Bone Mineral Density In Female Collegiate Dancers And Cheerleaders, Tara Sue Kenny, Damon Mccune, Laura J. Kruskall, James Navalta, John C. Young

Kinesiology and Nutrition Sciences Faculty Research

Bone mineral density reflects an athlete’s cumulative history of energy availability, physical activity, and menstrual status, as well as nutritional and environmental factors. Although sports with high-impact loading are associated with higher bone mineral density than low-impact or non-impact sports, confounding variables are differences in the athletes’ body size and sport-specific training. The purpose of this study was to determine if bone mineral density (BMD) and vitamin D status are different between two groups of female collegiate athletes who have comparable body size/weight requirements, but who engage in qualitatively different training regimens. Full body, spine and dual femur BMD was …

Studies were eligible for inclusion if they met the following criteria: 1) were an experimental trial published in an English peer-reviewed journal; 2) compared the effects of inorganic nitrate consumption with a non-bioactive supplement control or placebo; 3) used a quantifiable measure of exercise performance; and 4) was carried out in apparently healthy participants without disease. A total of 29 studies were identified that investigated the effects of nitrate supplementation on exercise tolerance …

Effects Of An Acute High-Volume Isokinetic Intervention On Circulating Levels Of Tnf-Α And Stnfr: Influence Of Age, Eliott Arroyo Delgado

Electronic Theses and Dissertations

The immune system has been implicated in recovery and muscle regeneration following exercise. In response to muscle damage, the immune system responds with an increase in circulating pro-inflammatory cytokines with the goal of recruiting leukocytes to the damaged area. Tumor Necrosis Factor-alpha (TNF-α), in particular, has been shown to be implicated in both muscle regeneration and muscle wasting. However, it remains unclear whether TNF-α is responsible for the age-related losses in muscle size and function. Also, due to the high clearance rate of TNF-α from circulation, analyzing the circulating levels of soluble TNF-α receptors 1 and 2 (STNFR1 and STNFR2) …

Effects Of An Acute High-Volume Isokinetic Intervention On Inflammatory And Strength Changes: Influence Of Age, Joseph Gordon

Electronic Theses and Dissertations

PURPOSE: The purpose of this study was to compare the effects of a high volume isokinetic intervention on lower body strength and inflammation, as well as markers of muscle damage in the subsequent 48 hours between younger and middle-aged men. METHODS: 19 healthy, recreationally trained men were randomly assigned to two groups, younger adults (YA: 21.8 ± 2.0 y; 90.7 ± 11.6 kg; 21.5 ± 4.1 % body fat), or middle-aged adults (MA: 47.0 ± 4.4 y; 96.0 ± 21.5; 24.8 ± 6.3 % body fat). Both groups reported to the human performance laboratory (HPL) on four separate occasions. On …

The Effects Of Sprint Interval Training And Maturity Status On Metabolic And Neuromuscular Fatigue Thresholds In Adolescents, Kyle Beyer

Electronic Theses and Dissertations

Purpose: To examine the maturity-related differences in the adaptations to systemic and localized fatigue thresholds (FTs) in response to sprint interval training (SIT) amongst adolescent male athletes. Methods: Twenty-seven adolescent male athletes, 11-17 years of age, completed pre-testing, six weeks of SIT, and post-testing. Participants were grouped according to their number of years from peak height velocity (PHV), an estimation of somatic maturity status, into PRE ( < -1.5yr), PERI (between -1.5 to +1.5yr) and POST ( > +1.5yr) PHV groups. Each testing session consisted of a ramp exercise protocol on a cycle ergometer. During the protocol, three systemic FTs, gas exchange threshold, ventilatory threshold, and respiratory compensation point were calculated …

Vocal Function Exercises For Normal Voice: With And Without Semi-Occlusion, Megan Suzanne Brown

Theses and Dissertations--Communication Sciences and Disorders

The primary purpose of this investigation was to explore the effects of varying degrees of vocal tract semi-occlusion in Vocal Function Exercises (VFEs) on attainment of pre- established maximum phonation time (MPT) goals in individuals between the ages of 18 and 45 with normal voice. Individuals were randomized into three experimental groups: the traditional VFE with a semi-occluded vocal tract (SOVT), modified /o/ with partial occlusion, and modified /a/ without significant occlusion. For six weeks, the participants completed the four exercises two times each, twice daily on corresponding vocal tract postures assigned by group. Results indicated significant change in percent …

The Effects Of Off-Season And In-Season Training On Lactate Threshold In Ncaa Division Iii Female Soccer Players, Rachael M. Nelson

Departmental Honors Projects

Soccer requires a significant amount of aerobic and anaerobic training to improve one’s performance. Because lactate threshold (LT) is an important component of endurance sport performance, testing the LT of soccer players in response to their off-season and in-season training regimens could help to gauge the success of those programs in improving or maintaining fitness levels. This study evaluated the effects of off-season training and in-season training types on LT in 11 NCAA Division III female soccer players (age 19.5 +/- 1.3 years). Off-season training was comprised of aerobic and anaerobic workouts, while in-season training was more sport-specific, and involved …
