Effects Of Service-Learning On Kinesiology Students' Attitudes Toward Children With Disabilities, José Santiago, Jihyun Lee, Emily Roper

Faculty Publications

Contact theory (Allport, 1954) served as the framework to investigate undergraduate kinesiology students’ attitudes toward children with disabilities after a service-learning (SL) experience. Fifty-one undergraduate kinesiology students enrolled in an adapted physical education (APE) course served as the experimental group, and 31 undergraduate kinesiology students enrolled in an introductory kinesiology course served as the control group. The Attitudes Toward Disabled Persons Scale–Form A (Yuker, Block, & Younng, 1970) was administered at three different times: before, during, and after the SL. A mixed-design ANOVA revealed that there were no statistically significant main or interaction effects for gender, group, and time on …

Frontal Plane Comparison Between Drop Jump And Vertical Jump: Implications For The Assessment Of Acl Risk Of Injury, Guilherme Manna Cesar, Curtis L. Tomasevicz, Judith M. Burnfield

Athletic Performance Research

The potential to use the vertical jump (VJ) to assess both athletic performance and risk of anterior cruciate ligament (ACL) injury could have widespread clinical implications since VJ is broadly used in high school, university, and professional sport settings. Although drop jump (DJ) and VJ observationally exhibit similar lower extremity mechanics, the extent to which VJ can also be used as screening tool for ACL injury risk has not been assessed. This study evaluated whether individuals exhibit similar knee joint frontal plane kinematic and kinetic patterns when performing VJs compared with DJs. Twenty-eight female collegiate athletes performed DJs and VJs. …

Is There A Difference In Acute Memory Retention Between Maximal Treadmill Exercise And Maximal Ergometer Exercise?, Elizabeth Jumbo

Kinesiology Student Research - Archive

INTRODUCTION: Physical activity can have positive effects on the proper functioning of the brain. A single bout of exercise may stimulate plasticity within the cortex, a portion of the brain with a unique applicability to reconstruct memory. There are a couple key components of the physiological effects of exercise on the brain that may control the improvements in memory. During a single bout of exercise, heart rate and stroke volume increase to pump more oxygenated blood throughout the body. Elevated cardiac output results in increased cerebral blood flow, which stimulates elevated electrical activity within the brain. A rise in frequencies …

To examine the factor structure, reliability, validity, and item functioning for gender invariance of the 15-item DRS with 525 collegiate athletes from a wide range of sports. Convergent and divergent validity were examined through relationships with mental toughness, grit and competitive anxiety. Participants completed measures of mental toughness, optimism, grit, competitive anxiety, and the DRS-15. Confirmatory Factor Analysis revealed a poor fit for the three-factor hardiness model, and subsequent exploratory factor …

The Effects Of Music On A Submaximal Exercise Performance, Ashley Gonzales, Sabrina Garcia

Kinesiology Student Research - Archive

INTRODUCTION: Individuals who work out several times a week often use music as a motivation or a distraction. However, will listening to music actually help the individual workout harder and longer or is it just a distraction affecting the intensity of the exercise. It has been suggested that music is more beneficial for longer distances and improves performance by “distracting” the individual who is exercising. PURPOSE: The purpose of this study was to investigate the effects of music on a 30-minute submaximal exercise test on the cycle ergometer. METHODS: Five males (age 21.4 ±1.62 yrs) of the UTA Kinesiology department, …

The Effects Of Body Weight Assistance On Maximal Aerobic Capacity In College Age Women, Sabino Rojas, Max Tosaw

Kinesiology Student Research - Archive

Maximal oxygen consumption, or VO2max is the maximal capacity for the body to deliver and utilize oxygen during an intense exercise. VO2max can be expressed as an absolute value in liters of oxygen per minute (L/min) or in a relative value as milliliters of oxygen per kilogram of body weight per minute (ml/kg/min). Body weight assistance (BWA) is often used within the rehabilitation setting as a reliable resource to provide patients the ability to perform a walking motion at a reduced body weight. The AlterG Anti-Gravity Treadmill utilizes the Differential Air Pressure technology to alleviate the individual’s weight. Research has …

The Relationship Between Rpe And Blood Lactate Concentrations During A Vo2max Test On A Cycle Ergometer, Edith Torres, James Nguyen

Kinesiology Student Research - Archive

INTRODUCTION: Lactate (La) is produced by the body’s muscles in response to exercise through anaerobic glycolysis. During exercise, most of the lactate produced enters the heart and slow twitch muscle fibers by traveling within the blood throughout the body. The lactate diffused into the blood is referred to asblood lactate. Blood lactate (BLa) is used as a measurement of exercise intensity since there is a strong relationship between the two. With increasing blood lactate and intensity there is also an increase in exertion. This exertion during exercise is measured through the rate of perceived exertion scale (RPE). The Borg RPE …

The Effects Of Caffeine On Maximal Exercise, Amber D. Rey, Brenda Romero

Kinesiology Student Research - Archive

Caffeine is classified as an ergogenic and central nervous system stimulant. Research shows that there are benefits of consuming caffeine. These include increased mental alertness, decreased fatigue and increased delay to the onset of fatigue, decreased reaction time and increased use of muscle triglycerides. Research has also shown that ingesting caffeine prior to exercise significantly elevates plasma levels of free fatty acids (FFA) and glycerol. It is known that the accumulation of FFA reduces the rate of glycolysis via the inhibition of phosphofructokinase. Therefore, ingestion of caffeine is expected to alter carbohydrate metabolism and the rate of lactate production.

The Effects Of Arginine On The Rate Of Blood Lactate Removal Following Multiple Wingate Tests, Robert Loflin, Nathan Mcewen

Kinesiology Student Research - Archive

INTRODUCTION: During the first few minutes of high intensity exercise, the body relies on the glycolytic system for energy. Abyproduct of this system is lactic acid, or blood lactate. As blood lactate levels increase in the muscles, muscle contraction and energy output decreases as a result ofoverall elevated acidity. Therefore, an athlete in successive high intensity events may be interested in supplementation that could rid the body more quickly of blood lactate. Onesupplement that might be beneficial in this task is Arginine, a common pre-workout vasodilator. PURPOSE: To determine what effects Arginine, a vasodilator, had on blood lactate removal after …

Validation Of An Error Sonification Auditory Feedback Training Program On Proper Sagittal Plane Squat Technique, Rena Hale

Open Access Theses & Dissertations

Osteoarthritis (OA) is one of the most common degenerative joint diseases that hinders an individual's quality of life. A large portion of knee OA instances can be correlated to previous anterior cruciate ligament (ACL) injury. Knee joint injury leading to OA is most prevalent in males aged 20-55 years old and can be caused by improper form during execution of a given task or lack of neuromuscular control. Screening protocols are used to assess deficits of an athlete, with the goal of reducing the risk of injury during both training and in competition. Neuromuscular training programs have been created to …

Medical Claims At Ncaa Institutions: The Athletic Trainer's Role, Tyler P. Killinger

Honors Undergraduate Theses

Context: National Collegiate Athletic Association (NCAA) institutions are required to certify insurance coverage of medical expenses that result from athletically related injuries sustained while partaking in an NCAA event. This means that the student-athlete must be covered either by their parent’s/guardian’s insurance, their own personal insurance coverage, and/or the institution’s insurance program. Institutions assign this role to a variety of employees, including head athletic trainers (ATs), assistant ATs, athletic administrators, business managers, secretaries, or other institution employees. In 1994 Street, Yates, Lavery, and Lavery observed that the head AT was responsible for administering medical insurance/claims payment at 51% of the …

Comparison Of Isokinetic And Jumping Knee Torques, Synyoung Li

Kinesiology Student Research - Archive

INTRODUCTION: Isokinetic movements occur at a fixed angular velocity, regardless of torque applied by the subject. Isokinetic testing has been correlated with field tests and clinical predictions such as recovery from surgery. Peak torque at a given angular velocity is the most commonly measured variable. Although isokinetic tests are correlated with field tests such as the vertical jump, there is little research comparing the same variables. Three-dimensional motion capture systems can accurately model a subject’s movement. Software then models virtual skeletons based on the anatomical markers captured by the camera system. The virtual reconstruction of the subject provides kinetic and …
