INTRODUCTION: Energy drinks have become the soft drink of this millennium. They are commonly available everywhere including stores, schools and fitness centers. Yet, the effects of energy drinks, on metabolism at rest and during exercise, receive little attention. Ingredients in energy drinks such as caffeine and taurine are sympathetic stimulants and increase heart rate and blood pressure. However, it is unclear as to whether or not these effects actually improve exercise performance. Redbull is an example of an energy drink that is often consumed with the idea that it will improve performance during an exercise workout. PURPOSE The purpose of …

The Effects Of Caffeine On Blood Lactate Levels During Submaximal Exercise, Sara Cleveland
Kinesiology Student Research - Archive
INTRODUCTION: Blood lactate concentration reflects the balance between lactate production and clearance. It is considered a marker of exercise intensity and muscle glycolysis. It is expressed in mmol/L of lactate found in the plasma of blood. Research shows that caffeine, a stimulant with ergogenic properties, increases blood lactate levels. It is also shown to improve aerobic performance and increase time to exhaustion during exercise. The physiological underpinnings of caffeine-provoked endurance performance gains are not yet fully understood but may be related to enhanced calcium availability, adenosine receptor antagonism and consequential reductions in pain and perceived exertion, and augmented lipolysis and …

Physical Stress On The Body Using A Vo2 Max Test And Its Effects On Short-Term Memory In Male Students, Kimberly Alvarez
Kinesiology Student Research - Archive
Introduction. Research shows that rhythmic exercise changes in serotonin, epinephrine, norepinephrine and acetylcholine levels all affect cortical arousal and cognitive function (Potter & Keele, 2005). There are many reasons why the brain is affected during exercise. Some of these include: increased glucose, oxygen and nutrient levels to the brain. Exercise has been shown to enhance cognitive function in both short and long term memory. However, when the body is put under a large amount of physical stress, less oxygen is left in the brain due to the fact that the muscles require more of that oxygen and glucose. Does this …

The Effects Of Caffeine Consumption On The Blood Lactate Levels In Recreationally Active College-Aged Males, James S. Hoerig
Kinesiology Student Research - Archive
INTRODUCTION: Caffeine has become the most widely used drug in the world. This xanthene derivative causes an increase in catecholamines circulating throughout the blood, and is commonly used by athletes looking for an increase in athletic performance. Besides having a stimulating effect on the cardiovascular and nervous system, many report a decrease in their levels of perceived exertion while performing exercise in conjunction with the drug. Blood lactate is a common way to quantify objectively the levels of exertion an athlete may be experiencing during exercise, as it is shown to increase linearly with perceived exertion and muscular fatigue. Additionally, …

Kinesiology Student Research - Archive
Introduction: The ergogenic effect of caffeine on short-term, high intensity exercise has been shown to be controversial throughout the literature. Some studies have shown little to no effect on anaerobic power with caffeine supplementation while a select few have shown significant gains. Anaerobic power is the energy that is stored in muscles that is readily available at any time and can be accessed without the use of oxygen. It may be expressed as an absolute value in Watts (S) or as a relative rate in Watts per Kilogram (/Kg). Anaerobic power has long been an integral part of sports that …

The Effect Of Post Activation Potentiation On An Isometric Bicep Contraction, Nickesh Mistry
Kinesiology Student Research - Archive
INTRODUCTION: Post activation Potentiation (PAP) is a new concept that has a need for further research. The performance of a muscle depends on the historic activity of that muscle. The concept of PAP is activating the muscle prior to maximal contraction. This concept works on the basis that the muscle has history of activating and, in turn, will be able to produce a greater force and torque. This idea was utilized with a biceps isometric contraction. An isometric contraction is a contraction where the joint angle as well as the muscle length is not going to change during the contraction. …

The Comparison Of Vertical Jump Height Between Gender And Body Fat Percentage, Allison Jack
Kinesiology Student Research - Archive
INTRODUCTION: Vertical jump height is seen as a muscle performance test that indicates power and force production. It is a kinematic measure used to determine the differences between males and females based on their frontal plane hip angle. Along with different hip angles, males also have greater leg girths than females that could be an anthropometric measurement that influences power production. Males generally have a greater vertical jump height than females with arm swing because of their upper body strength, which influences power production. This is an important factor when determining training program and types of exercises because males and …

Effects Of Dynamic Vs Static Warm-Ups On Athletic Performance In Youth, Morgan Melton
Kinesiology Student Research - Archive
INTRODUCTION: A typical warm-up involves some form of stretching depending upon the activity being performed. Stretches can be either dynamic (meaning they involve motion) or static (meaning they involve no motion). Dynamic stretches affect dynamic flexibility and static stretches affect static flexibility (and dynamic flexibility to some degree). Static stretches are designed to hold a position for a joint/muscle that is minimally challenging. Dynamic movement stretches are designed to take a joint/muscle through a challenging and repetitive motion, moving a body part farther with each repetition. Research over the benefits and risks of static and dynamic stretching protocols during warming …

The Effects Of L-Carnitine Supplementation On Body Weight, Body Fat Percentage And Fat Metabolism, Mohamed Abdurahman
Kinesiology Student Research - Archive
INTRODUCTION: L-carnitine is a nutritional ergogenic aid. Long chain fatty acids are a major source of energy at rest and during exercise for the body. L-carnitine is an enzyme that transports these fatty acids to the mitochondria for beta oxidation. It has been theorized that by increasing L-carnitine availability, fat oxidation will be increased within the body and glycogen can be spared, thus, increasing aerobic endurance capacity. Previous studies have shown mixed results. PURPOSE: The purpose of this study was to determine whether 10 days of L-carnitine supplementation in a recreationally active college-aged sample would result in increased fat metabolism. …
