Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush

Masters Theses & Specialist Projects

The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perform the same intensity rotation (Counter …


The Effects Of Caffeine On A Time-Trial Cycling Performance, Chris Tucker 2011 University of Texas at Arlington

The Effects Of Caffeine On A Time-Trial Cycling Performance, Chris Tucker

Kinesiology Student Research - Archive

Caffeine is one of the most widely consumed drugs in the world. Its mechanism of action has given it credibility as an ergogenic aid. It has been shown to stimulate the mobilization and oxidation of free fatty acids (FFA), thus sparing muscle glycogen. Caffeine is also well documented as a central nervous stimulant and its direct effect on the central nervous system is found in its role as an adenosine antagonist. It is thought to inhibit adenosine from blocking neuronal transmission thus increasing pain tolerance and reducing fatigue.

Aerobic Capacity Of Wheelchair Basketball Players During Arm Crank Ergometry Vs Treadmill, Steve Quaker

Kinesiology Student Research - Archive

It is difficult to determine the aerobic capacity of wheelchair athletes by the accepted standards and methods of testing. The levels of disability and the associated functionality of the individual as well as wheelchair design itself impacts the measure of VO2 peak. VO2 peak is the maximum volume of O2 that a person's body can transport to tissue during incremental exercise. At the current time VO2 peak is the best indicator of physical fitness of an individual.

A maximal graded exercise test (GXT) will be performed via Bruce protocol to determine if maximal oxygen consumption (VO2 max), rate of perceived exerction (RPE), respiratory exchange ratio (RER), rate of respiration (RR) and …


The Effect Of Compression Sleeves On Blood Lactate During An Arm Ergometer Max Test, Sergio Daniel Arciniega 2011 University of Texas at Arlington

The Effect Of Compression Sleeves On Blood Lactate During An Arm Ergometer Max Test, Sergio Daniel Arciniega

Kinesiology Student Research - Archive

Among athletes, the use of compression sleeves has been widely used with the intentions of increased flexibility, improved blood circulation, and increased muscle oxygenation. Therefore, the performance enhancements provided by compression sleeves could affect the amount of lactic acid accumulated within the muscle. Lactic acid builds up in the muscles as a byproduct of anaerobic activity, which dissociates into lactate and H+ resulting in a decrease in pH and is thought to lead to muscle fatigue.

The Effect Of Cytomax Sports Drink On Blood Lactate Levels In A 400 M Run, Christina Driscoll 2011 University of Texas at Arlington

The Effect Of Cytomax Sports Drink On Blood Lactate Levels In A 400 M Run, Christina Driscoll

Kinesiology Student Research - Archive

During short term exercise, lactic acid is formed as a byproduct of glycolysis. It forms from pyruvate when oxygen is not present in the muscles. Lactic acid then diffuses from the muscles into the blood and is broken down into lactate and hydrogen ions. This excess of hydrogen ions causes the blood pH to lower, unless it is buffered by the body. Many substances such as sodium bicarbonate, superoxygenated water, and caffeine have been tested as buffers, but none has been found to be both safe and effective. A new product, Cytomax performance drink claims to be a buffer.

Effects Of Nitric Oxide Supplementation On Maximal Graded Exercise, Erin Lewis 2011 University of Texas at Arlington

Effects Of Nitric Oxide Supplementation On Maximal Graded Exercise, Erin Lewis

Kinesiology Student Research - Archive

Nitric oxide (NO) is a naturally occurring substance in the body. It is released during exercise, stimulating vasodilatation, which increases blood flow to the muscles. It has become a popular form of supplementation in the past few years, gaining popularity over creatine use (which it is now often stacked with). Companies introduced nitric oxide as a supplement similar to creatine; naturally occurring in the body to aid in exercise, and by increasing the supply, they claim that it would enhance the user’s exercise capacity. However, there are few studies done that test the actual physiological effects of nitric oxide supplementation …

The Effects Of Caffeine On A Time Trial On A Cycle Ergometer, Allen Conly

Kinesiology Student Research - Archive

Some people wake up in the morning and grab that cup of coffee to get a boost of energy to get moving. Why is it that coffee is used for this? Perhaps, it’s because of the ingredients found in coffee, like caffeine, in particular. Caffeine is used as a stimulant and a diuretic. A stimulant is an agent that enhances the activity of a body system or function. Because of its stimulating effects, caffeine is often used as an ergogenic aid. Caffeine can be used to stay awake or for better mental alertness in times of fatigue. An ergogenic aid …


Cryotherapy And Its Effects On Shoulder Proprioception, Spencer Elswick 2011 University of Texas at Arlington

Cryotherapy And Its Effects On Shoulder Proprioception, Spencer Elswick

Kinesiology Student Research - Archive

Proprioception, or the relative sense of body position in space, is accomplished by a complex integration of multiple sensory receptors within the skin, muscle, joints, ligaments, and tendons. These proprioceptors continually send afferent neural impulses to the central nervous system regarding peripheral joint stability and movement and are typically stimulated (excited) with tissue deformation via stretching or compression. However, when an athlete sustains an injury to a joint during competition, the joint is most commonly treated with a desensitizing treatment like cryotherapy. Ice application is used to interrupt pain sensation by decreasing nerve conduction velocity, inflammatory mediators, and metabolic byproducts. …


Functional Movement Screen Predicators: Can High Fms Scores Be Predicted Through Range Of Motion, Strength, And Balance Measures?, Jeremy L. Hester 2011 University of Texas at Arlington

Functional Movement Screen Predicators: Can High Fms Scores Be Predicted Through Range Of Motion, Strength, And Balance Measures?, Jeremy L. Hester

Kinesiology Student Research - Archive

There has been a steady increase in sport participation in the U.S. over the recent years, and with increases in activity comes a rise in the physical demands of sport on the musculoskeletal system. These demands coupled with increased sport activity can yield an increase in the risk of injury. Functional movement occurs in everyday life, and even more so in an athletic population. When these movements are imbalanced or biomechanically inefficient, breaks in the proper kinetic chain of movement will begin to occur. Compensatory movement will follow the bodies physical deficits, so early detection or proper intervention are important. …


Effects Of Vo2 Max Test On Short Term Memory, Olufemi Ola-Ajose 2011 University of Texas at Arlington

Effects Of Vo2 Max Test On Short Term Memory, Olufemi Ola-Ajose

Kinesiology Student Research - Archive

Exercise in healthy adults has been shown to small but positive effects on cognitive function. Short term or working memory is a limited storage system in which a memory is lost or decays rapidly. Short term memory is believed to support an array of complex cognitive behaviors such as reading comprehension and mathematical problem solving (Beilock & Carr, 2005). The effects of exercise intensity on short term memory is varied, although submaximal and moderate exercise bouts have been shown to have a positive effect on memory. Exercise causes changes in cardiorespiratory, hormonal and metabolic processes that may increase the availability …


The Effect Of Lactate Buildup As An Energy Substrate During A Short-Duration, High-Intensity Run Of 400-M And A Medium Run Of 800-M On Uta Kinesiology Students, Davor Krnjajic 2011 University of Texas at Arlington

The Effect Of Lactate Buildup As An Energy Substrate During A Short-Duration, High-Intensity Run Of 400-M And A Medium Run Of 800-M On Uta Kinesiology Students, Davor Krnjajic

Kinesiology Student Research - Archive

Lactic acid is a metabolic byproduct of the anaerobic glycolysis energy system present in blood and muscle. Some research indicates that lactic acid is a marker of fatigue during short duration exercise due to its dissociation into lactate and the H+ ion, whose accumulation in tissues and blood can lead to a subsequent decrement in muscle and plasma pH causing an inhibition of coupling mechanisms and enzymatic processes necessary for maintenance of muscular force production. Other studies have not implicated lactate to be the sole contributor of fatigue, as different types of exercise produce multifaceted fatigue factors, depending on muscle …
