Physiological And Biomechanical Response To Indoor Cycling With And Without The Ability To Sway, Alina P. Swafford
Physiological And Biomechanical Response To Indoor Cycling With And Without The Ability To Sway, Alina P. Swafford
UNLV Theses, Dissertations, Professional Papers, and Capstones
Introduction: Bicycles have been around since the early 19th century. Since the invention of the bicycle, it has taken on several purposes. People have used bicycles as a means of transportation, leisure, exercise, and sport. The number of individuals who participate in a cycling event per year has increased. With the increase in popularity, research related to cycling has also increased. Research related to the physiology and biomechanics of cycling are of particular areas of interest. Balance is a crucial component of understanding why we cycle a certain way. Some research has labeled balancing on a bicycle as cycling sway. …
Comparison Of Male And Female Ultramarathon Runners, Kelsey Klug
Comparison Of Male And Female Ultramarathon Runners, Kelsey Klug
UNLV Theses, Dissertations, Professional Papers, and Capstones
This research study investigates how specific running variables and demographic characteristics impact performance, or speed, for ultramarathon runners. These variables and characteristics include biological sex, cadence, age range, total distance of the race, duration of the race, years of running experience, total number of ultramarathon races ever completed, and number of races completed in the last twelve months. An ultramarathon is any running distance over a standard marathon or 42.2 kilometers. Participation in ultramarathons has increased by 345% since 2010, with females making up 23% of participants. No in-person data collection was necessary for this study. Participants were asked to …
The Influence Of Concussion History And Head Acceleration On Lower Extremity Function, Warren Forbes
The Influence Of Concussion History And Head Acceleration On Lower Extremity Function, Warren Forbes
UNLV Theses, Dissertations, Professional Papers, and Capstones
Sport-related concussions (SRCs) play a very debilitative role in athletics with between 1.7 – 3 million SRCs occurring annually (Clay et al., 2013; Zuckerman et al., 2015). This equates to upwards of 21.5 SRCs per 1000 athletic exposures. Research pertaining to SRC has received intense focus because of the substantial financial impact on the US healthcare system as well as the negative impact that SRCs have on the quality of life of athletes. Much of the research concerning SRC has been centered around management and ensuring adequate recovery from SRC-related symptoms. The current return to play (RTP) criteria from an …
Depression, Anxiety, And Estimated Cardiorespiratory Fitness In College Students, Christian Ison
Depression, Anxiety, And Estimated Cardiorespiratory Fitness In College Students, Christian Ison
UNLV Theses, Dissertations, Professional Papers, and Capstones
Depression and anxiety disorders are two common mental health conditions worldwide. College students are considered a high-risk population for the development of these conditions. Improved cardiorespiratory fitness (CRF) has been shown to decrease depression and anxiety risk, symptoms, and severity but this relationship and the extent to which improved CRF can reduce these risks has yet to be examined in the college student population. Validated and reliable non-exercise estimated cardiorespiratory fitness (eCRF) algorithms could be used to identify relationships and associations with depression and anxiety severity levels among college students. The purpose of this study was to assess eCRF and …
Oxygen Consumption In Highly Skilled Baseball Pitchers, Jesse Clingman
Oxygen Consumption In Highly Skilled Baseball Pitchers, Jesse Clingman
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to describe the physiological demands of highly skilled baseball pitchers during pitching, along with pitch metrics. Three junior college and three professional (n = 6) baseball pitchers participated in this study. Participants completed a graded exercise test (GXT) to volitional exhaustion to determine maximal oxygen consumption (VO2 max) and estimated body fat percentage, height, and body mass were measured on day one of testing. Next, participants faced live batters on a baseball field while wearing a portable metabolic analyzer (Cosmed K5) to measure respiratory gases including oxygen consumption (VO2) and carbon dioxide produced (VCO2) …
The Influence Of Transcranial Alternating Current Stimulation On Fatigue Resistance, Kayla De Guzman
The Influence Of Transcranial Alternating Current Stimulation On Fatigue Resistance, Kayla De Guzman
UNLV Theses, Dissertations, Professional Papers, and Capstones
Fatigue is an exercise-induced reduction in muscle force generating capacity. Several studies have shown that some forms of non-invasive brain stimulation can increase the resistance to fatigue during sustained isometric contractions. The purpose was to determine the influence of transcranial alternating current stimulation (tACS) on the time to task failure (TTF) of a precision grip task in young adults. Twenty-two healthy young men and women participated in the study. The study utilized a randomized, double-blind, SHAM-controlled, within-subjects, crossover design. Each participant completed two experimental sessions (tACS, SHAM) with a 7-day washout period between sessions. Each session involved performance of a …
Physiological Effects Of A Traditional Active Warm-Up Versus A Passive Warm-Up During Submaximal Endurance Exercise, Vernice Ollano
Physiological Effects Of A Traditional Active Warm-Up Versus A Passive Warm-Up During Submaximal Endurance Exercise, Vernice Ollano
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study is to investigate physiological responses during a traditional active warm-up and a passive warm-up consisting of wearing heated trousers during a submaximal endurance cycling workout. Participants included 10 cyclists/triathletes (3 females, 7 males; age: 48 ± 13 years old; mass: 157.9 ± 33.8 kg; height: 169.3 ± 8.65 cm; percent body fat: 25.3 ± 8.53 %) of at least 18 years of age who could continuously cycle for at least 120 minutes and had knowledge of their individual FTP. Experimental 1-day testing included a randomized crossover design where participants proceeded with two different protocols: an …
Musculoskeletal Injury Concealment In The Reserve Officers’ Training Corps, Joshua D. Wooldridge
Musculoskeletal Injury Concealment In The Reserve Officers’ Training Corps, Joshua D. Wooldridge
UNLV Theses, Dissertations, Professional Papers, and Capstones
INTRODUCTION: Among service members, musculoskeletal injuries threaten military readiness and place a substantial burden on medical and financial resources. While musculoskeletal injuries (MSKIs) are a leading threat to military readiness, service members’ unwillingness to seek care constrains current prevention and surveillance efforts. A growing body of evidence shows US service members conceal a large proportion of injuries, especially in training environments. The Reserve Officers’ Training Corps is a critical training environment for future US military commissioned officers. Reserve Officers’ Training Corps (ROTC) is the largest commissioning source of new officers for the US military. ROTC cadets are college students concurrently …
