Physiological Responses During A Modified Bruce Max Test In The Anti-Gravity Treadmill, Lucy Kang
Kinesiology Student Research - Archive
INTRODUCTION: Physical activity can be difficult or painful for the obese, disabled, or those recovering from injury or surgery. For all populations, regular physical activity is a necessity for overall health, increased mobility, and reduction of all-cause mortality rates. Lower body positive pressure (LBPP) treadmills offer a way to unweigh users in an effort to reduce reaction forces that may inhibit physical activity and are less painful than traditional harness systems. To address this, the physiological responses in the AlterG© Anti-Gravity treadmill were measured, while performing a modified Bruce max test. The measurements take were the RPE, absolute and relative …

Comparing Unilateral Transfer Of Mucsle Activity For Reaction Time For Right And Left Handed Individuals, Adam Grillo
Kinesiology Student Research - Archive
INTRODUCTION: Fitts’ law is a descriptive model of human movement that states the time required to rapidly move to a target areas is a function of the ratio between the distance to the target and the width of the target. This means for simple tasks such as a simple bicep curl, the distance and targeted area are short and easy to hit. If one side of the body goes through this simple task, the opposite side will have a better idea of what to expect through what is called bilateral transfer. However unilateral transfer of muscle activity, were someone works …
Effects Of Beta-Alanine Supplementation On Blood Lactate Levels On Maximal Exercise, Yovany Servin
Effects Of Beta-Alanine Supplementation On Blood Lactate Levels On Maximal Exercise, Yovany Servin
Kinesiology Student Research - Archive
INTRODUCTION: A physiological measure of ten used to detect metabolic changes during exercise is measurement of blood lactate concentration. Lactate is produced by working muscle and is the end-product of an aerobic glycolysis. Some of it diffuses into the blood, and during exercise, heart fibers and ST fibers in working muscle take up most of the lactate and convert it back into pyruvate, which then enters the Krebs cycle (aerobic system). During exercise recovery, however, most of the lactate is removed from blood by the liver. Certainly, blood lactate concentrations reflect exercise intensity. However, the rapid accumulation of lactate in …

Enhancing Muscular Performance In Men: Traditional Resistance Training Compounded With Plyometric Training In A 6-Week Training Program, Tanner Houston
Kinesiology Student Research - Archive
INTRODUCTION: In-season training for athletes is a tricky time when it comes to maintaining performance on the field. They spend all off-season training their bodies to perform at peak performance when the game is on the line, but during the season training can be a totally different story. The combination of games, practices, and workouts during a season can lead to an early onset of fatigue that can decrease performance prematurely either late in games or throughout an entire prolonged season, so training regimens are bolstered to decrease the intensity during the season to where players can last the entire …
The Effects Of Acute Dietary Nitrate Supplementation On Maximal Exercise Performance, Zachary Blankenship
The Effects Of Acute Dietary Nitrate Supplementation On Maximal Exercise Performance, Zachary Blankenship
Kinesiology Student Research - Archive
INTRODUCTION: Beet juice has recently become a growing dietary supplement used by athletes to improve exercise performance. Beet juice is high in dietary nitrates which is absorbed in the upper gastrointestinal tract. The nitrate is then converted into nitrite which is further reduced to nitric oxide. Nitric oxide regulates muscle blood flow via vasodilation and mitochondrial respiration. Research shows that dietary nitrate supplementation reduces the oxygen cost of submaximal exercise for the same workload. This results in more mechanical efficiency of muscle contraction. PURPOSE: The purpose of this experiment was to determine if dietary nitrate improves aerobic exercise performance. METHODS: …

Effectiveness Of Recovery Methods On Clearance Of Blood Lactate After Strenuous Exercise On Jiu-Jitus Athletes, Jordan Shepler
Effectiveness Of Recovery Methods On Clearance Of Blood Lactate After Strenuous Exercise On Jiu-Jitus Athletes, Jordan Shepler
Kinesiology Student Research - Archive
Introduction: Blood lactate is one of the most measured parameters during performance testing of athletes. With high intensity training comes an increased level of blood lactate. If not properly cleared, elevated blood lactate levels are associated with impaired muscle function as well as reduced exercise performance. Previous studies have demonstrated that active recovery (AR), performing low intensity aerobic exercise post exercise is more effective at clearing lactate than rest/ passive recovery (PR). Whole-body Cryotherapy (WBC) has recently gained popularity for improving recovery after strenuous exercise as an alternative to traditional ice-water therapy. Subjects enter a specially designed cabin in which …

Effects Of Fasting On Submaximal Exercise, Lenia Rodriguez
Kinesiology Student Research - Archive
INTRODUCTION: Glucose is the primary energy source for the human body. It is obtained through eating carbohydrates among other things. Its chemical energy contributes to the generation of ATP during aerobic respiration. Glucose is stored in the body’s muscles and liver as glycogen where it can then be readily converted back to its original form. Studies have now shown there to be benefits from fasting before exercise. When eating carbs before a workout it promotes energy storage, inhibits the sympathetic nervous system and therefore reduces fat burning. In the fasting condition process such as energy storage cease. PURPOSE: The purpose …

Introduction: Zumba is a dance fitness exercise with Latin rhythm including dance movements such as salsa, rumba, and merengue. Previous studies have shown that aerobic dance training programs do not necessarily produce the same aerobic adaptation responses in cardiorespiratory capacity as running, however exercise intensity can be assessed in different ways: blood pressure (BP), heart rate (HR), and Borg’s rate of perceived exertion (RPE) scale. The purpose of this study was to evaluate the effect of Zumba on fitness levels during YMCA graded exercises testing in a two week period Methods: Three women (W; age 40.0 + 4.16 yrs) and …
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 - Archive
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 …

A Comparison Of Continuous And Intermittent Exercise Effect On Excess Post-Exercise Oxygen Consumption (Epoc), Kelly Tran
Kinesiology Student Research - Archive
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 Caffeine On Anaerobic Performance, Babak Mouri
Kinesiology Student Research - Archive
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 …
