Kinesiology Student Research - Archive
Research has shown that more anaerobically fit soccer players make for better defenders, while the more aerobically fit players are better off being used on the offensive side of the pitch. The Wingate is an anaerobic test, most often performed on a cycle ergometer, which is used to measure peak anaerobic power, as well as anaerobic capacity. On the other hand, maximal oxygen consumption (VO2max) is the maximum capacity of the body to transport and utilize oxygen (aerobic) during incremental exercise. To obtain VO2max, the Bruce Protocol, which is a standardized multistage treadmill test for assessing cardiovascular health, was used.

The Benefits Of Motor Imagery On Upper Limb Strength, Janet Pacheco
The Benefits Of Motor Imagery On Upper Limb Strength, Janet Pacheco
Kinesiology Student Research - Archive
Motor Imagery (MI) is a dynamic state in which an individual mentally stimulates a given action, without an actual motor output. The primary function is to allow the individual to generate a specific predetermined and possible outcome based on past experiences. A generous portion of MI research is primarily focused on rehabilitation rather than a strength training setting. In many cases when a patient is unable to execute a physical movement, the next most relevant scenario is to visualize the execution of that specific movement. Research suggests an increase in strength may be due to an improvement of the motor …

Kinesiology Student Research - Archive
INTRODUCTION: Caffeine is considered the most widely used stimulant in the world. According to the American College of Sports Medicine (ACSM) the average consumption of caffeine in the USA is approximately 2 cups of coffee per day (200 mg). Caffeine is often referred to as a nutritional ergogenic aid, but it has no nutritional value. Caffeine that is ingested is rapidly absorbed from the stomach and peaks in the blood within the first two hours. Caffeine has the potential to affect all systems of the body, as it is absorbed by most tissue. The remaining caffeine is broken down in …

Pre-Cooling Interventions And The Physiological Effects With Intermittent-Sprinting, Josue Flores
Kinesiology Student Research - Archive
BACKGROUND: Thermoregulation is stated as the potential of an organism to sustain a core body temperature within parameters, as external and internal temperatures are constantly fluctuating from day to day. Exercise, illnesses or intense external conditions are factors that cause elevated core body temperature that can disrupt cellular activity. Literature has shown that in order for the body to allow for physiological processes to occur efficiently it is necessary to be in a homeothermic state. The hypothalamus is the prime mechanism that regulates the core body temperature to maintain it within a normal resting range of 97.0-100.0 ˚F. Hence, the …

Kinesiology Student Research - Archive
Introduction: Exercise is commonly followed by fatigue which an athlete usually tries to minimize with the intake of protein supplements and high protein diets. The fatigue felt by the athlete can have an effect on his or her ability to perform at the same level while focusing on similar muscle groups. Increasing protein intake speeds up the recovery process of the muscles used during exercise, and measurements such as maximal oxygen consumption (VO2max) can be used to determine whether or not the athlete can perform exercise at the same level of intensity while targeting the same muscle groups. The VO2max …

The Effect Of Warm-Up Techniques On Foot, Ankle And Lower Leg Stability In A College-Age Population, S Laine
The Effect Of Warm-Up Techniques On Foot, Ankle And Lower Leg Stability In A College-Age Population, S Laine
Kinesiology Student Research - Archive
Common warm-up techniques attempt to prepare the body for tasks that may require higher physiological response. The increase in temperature with warm-ups tends to speed nerve conduction velocity, attenuate muscle spindle sensitivity, and decrease tissue stiffness. Passive (hot pack or massage) or active (low intensity aerobic) warm ups that target the specific joint or muscle may be more effective than general body warm-ups. Localized hot pack application and joint mobilizations may better stimulate musculotendinous tissue thereby allowing more effective preparation for tasks that require a high neurological response.

The Effects Of Caffeine On Blood Lactate Levels During Submaximal Exercise, Sara Cleveland
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 …

INTRODUCTION: Manual muscle testing (MMT) is utilized in different fields like physical therapy and other fields that require diagnosis of a person’s muscular strength and progression over time. MMT involves stabilization of a certain part of the body while external resistance is provided by the manual muscle tester. Muscular activity is graded on a 0 to 5 scale. Another way to measure muscle activation is by electromyography (EMG). EMG uses electrodes to record electrical activity produced by a muscle. PURPOSE: The purpose of the study was to determine the relationship between ratings of muscular activity by pre-physical therapy students and …
The Effect Of Post Activation Potentiation On An Isometric Bicep Contraction, Nickesh Mistry
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
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. …
