To Stretch Or Not To Stretch: Comparison Of Static And Dynamic Stretches, Jenny Nelson, Kripa Thomas, Kreshun Neal, Jenifer Caraveo, Jennifer Howard
Kinesiology Student Research
Static stretching is a primary component in the warmup routine of athletes (Beckettetal.2009). It consists of stretching the muscles while at rest for about 30 seconds. This type of stretching is believed to aid in athletic performance and decrease the risk of injury and muscle soreness (Beckettetal.2009). Athletes warm-up with stretching to prepare them in their training or competition, believing that these routines will help them in their performance (Fletcheretal.2007). Research has shown a decrease in muscular performance with static stretching being a part of the warm-up routine (Fletcheretal.2007). Six women (W;age23.3+1.21yrs) and nine men (M;age24.4+2.74yrs), participating in this study. …
Effects Of Caffeine On Anaerobic Performance, Babak Mouri
Effects Of Caffeine On Anaerobic Performance, Babak Mouri
Kinesiology Student Research
INTRODUCTION: Anaerobic performance refers to high intensity, short duration exercise performance focusing on speed and power. These are short duration exercises with a high intensity, lasting from three seconds to a maximum of two minutes. The predominate systems within the body working during these performances are the adenosine triphosphate and phosphocreatine (ATP-PC) systems which utilizes stores in the muscle and anaerobic glycolysis which generates ATP and leads to the metabolic byproduct, lactic acid. Caffeine is a central nervous system (CNS) stimulant. This drug increases the metabolism of fatty acids, and in turn spares muscle glycogen to enhance performance. Glycogen is …

Effects Of Upper Body Exercise On Physiological Variables In Men And Women, Kreshun Neal
Effects Of Upper Body Exercise On Physiological Variables In Men And Women, Kreshun Neal
Kinesiology Student Research
Introduction: Monitoring exercise intensity during an exercise bout is important to provide feedback. Monitoring heart rate, blood lactate, and rate of perceived exertion provide useful information that give feedback to the exerciser. Research has suggested that rate of perceived exertion is more of an appropriate measure of exercise intensity than individual physiological variables and that RPE can be correlated with other physiological measures such as heart rate and blood lactate. With the pain scale (VAS) research has shown that it tends to restrict the rating behavior into a linear regression whereas the RPE has an incremental curve because it is …

Effects Of Compression Shorts On Thermoregulation During Maximal Exercise, Tiffany Horn
Kinesiology Student Research
INTRODUCTION: In response to exercise, heart rate, systolic blood pressure, breathing rate, oxygen consumption and body temperature increase. Since the body is homoeothermic and attempts to remain in a narrow range of temperatures, the body attempts to regulate the temperature during exercise. Clothing insulates the body and reduces evaporation which is the main process of heat loss during exercise. Clothing fabrics such as compression have been advertised to promote cooling, improve performance and result in a faster recovery. PURPOSE: The purpose of this study was to determine if wearing compression shorts during maximal exercise effects the body’s ability to regulate …

Physiological Change Through Aerobic Exercise Under Hypoxic Conditions With An Elevation Mask, Bryan Laurel, Kyle Morone, Tai Nguyen, Fadey Suleiman, Kenny Tran, Vince Tran
Kinesiology Student Research
Athletes have found a new way to train to get an edge over their competitors and that is to train in an environment where oxygen is lacking. With a lower supply of oxygen, the body produces the hormone erythropoietin, which stimulates the bone marrow to create more red blood cells to form more hemoglobin. Hemoglobin are proteins inside red blood cells that carries oxygen to the tissues while bring carbon dioxide back to the lungs. When the athlete come back to normal elevation level, he or she usually holds an advantage over their competition due to their temporary elevated hemoglobin …

Range of motion (ROM) is the specific movement of a joint- measured in degrees. It is important to know techniques to apply that will give people the best ROM. With myofascial release (MFR), the object is to fix muscular restrictions while ROM is restored. Reestablishing ROM after pathology is essential for activities of daily living or athletics. Studies have discovered that MFR interventions were effective in reducing hamstring tightness versus no treatment on hamstrings.
A Comparison Of Continuous And Intermittent Exercise Effect On Excess Post-Exercise Oxygen Consumption (Epoc), Kelly Tran
Kinesiology Student Research
INTRODUCTION: As individuals conduct exercise, the body’s oxygen consumption rate is elevated to provide the increase oxygen demanded by the working muscles. During recovery, oxygen consumption declines but remains elevated above pre-exercising resting levels. The length of time that oxygen consumption remains elevated is dependent on the intensity and duration of the exercise, as well as the fitness level of the individual. The oxygen that is consumed above resting levels during recovery is referred to as excess post-exercise oxygen consumption (EPOC). PURPOSE:The purpose of this study is to determine if there is a difference in excess post-exercise oxygen consumption between …

Effects Of Verbal Encouragement On Anaerobic Field Tests, Lawrence Adeniseun
Kinesiology Student Research
IntroductionAnaerobically our bodies generate energy using two different energy systems. The first energy system uses adenosine triphosphate and creatine phosphate. It supplies energy for no more than 6-8 seconds. Activities like jumping and running for short periods of time utilize this energy system. The short-term anaerobic system also produces high-powered energy. However, it is a little more enduring and can provide energy for up to 90 seconds. Runners in the 400m event use this energy system. Motivation has consistently been used as a variable to study performance. Some studies have shown no effects of external motivation on anaerobic test performance …

Measuring Increases On Anaerobic Power By Verified And Non-Verified Pre-Workout Supplements, Joshua Beaty, David Martinez, Brittany Moore, Kimberly Vela
Kinesiology Student Research
Anaerobic exercise is often defined as any short-duration exercise that is powered primarily by metabolic pathways that do not use oxygen. The Wingate test measures peak power and anaerobic capability. The main energy system powering anaerobic exercise is the ATP-PC system, however, during the Wingate test the glycolytic pathway also provides some of the energy. Pre-workout supplements are used as aids to increase tolerance and muscle contractility and provide a short burst of energy during physical activity.

Blood Lactate Clearance During Passive Recovery With Kinesiology Tape Following Maximal Exercise, Marissa A. Miller
Kinesiology Student Research
NTRODUCTION: Kinesiology tape is an elastic cotton blend fabric strip with an adhesive backing. Many different manufacturers claim that their product reduces muscle fatigue and increases blood flow by lifting the skin up off of the underlying fascia and capillaries. This lifting creates a low-pressure are a beneath the skin, referred to as the decompressed skin. Skin that is not decompressed (skin around tape)is said to have a higher pressure, causing the fluids to move from the areas of higher pressure to areas of lower pressure. This fluid dynamic is the basis for the claims that the tape increases blood …

Effects Of Temperature Change On Fluid Intake On Performance, Juanjose Tello
Effects Of Temperature Change On Fluid Intake On Performance, Juanjose Tello
Kinesiology Student Research
INTRODUCTION: Fluid intake during exercise is a very important aspect to both health and performance of an athlete. It is known that during exercise, an increase in exercise intensity causes an increase in HR, breathing rate, VO2(L/min), and other physiologic variables. The body must rid itself of heat that builds up due to the breakdown of energy providers such as glycogen, protein, fat, and blood glucose and muscle contraction. Body temperature is another variable that is affected by increase in exercise, but proper hydration helps aid the body in getting rid of excess heat and helps return the body to …
