The Relationship Between Rpe And Blood Lactate Concentrations During A Vo2max Test On A Cycle Ergometer, Edith Torres, James Nguyen
Kinesiology Student Research - Archive
INTRODUCTION: Lactate (La) is produced by the body’s muscles in response to exercise through anaerobic glycolysis. During exercise, most of the lactate produced enters the heart and slow twitch muscle fibers by traveling within the blood throughout the body. The lactate diffused into the blood is referred to asblood lactate. Blood lactate (BLa) is used as a measurement of exercise intensity since there is a strong relationship between the two. With increasing blood lactate and intensity there is also an increase in exertion. This exertion during exercise is measured through the rate of perceived exertion scale (RPE). The Borg RPE …
The Effects Of Caffeine On Maximal Exercise, Amber D. Rey, Brenda Romero
The Effects Of Caffeine On Maximal Exercise, Amber D. Rey, Brenda Romero
Kinesiology Student Research - Archive
Caffeine is classified as an ergogenic and central nervous system stimulant. Research shows that there are benefits of consuming caffeine. These include increased mental alertness, decreased fatigue and increased delay to the onset of fatigue, decreased reaction time and increased use of muscle triglycerides. Research has also shown that ingesting caffeine prior to exercise significantly elevates plasma levels of free fatty acids (FFA) and glycerol. It is known that the accumulation of FFA reduces the rate of glycolysis via the inhibition of phosphofructokinase. Therefore, ingestion of caffeine is expected to alter carbohydrate metabolism and the rate of lactate production.

The Effects Of Arginine On The Rate Of Blood Lactate Removal Following Multiple Wingate Tests, Robert Loflin, Nathan Mcewen
Kinesiology Student Research - Archive
INTRODUCTION: During the first few minutes of high intensity exercise, the body relies on the glycolytic system for energy. Abyproduct of this system is lactic acid, or blood lactate. As blood lactate levels increase in the muscles, muscle contraction and energy output decreases as a result ofoverall elevated acidity. Therefore, an athlete in successive high intensity events may be interested in supplementation that could rid the body more quickly of blood lactate. Onesupplement that might be beneficial in this task is Arginine, a common pre-workout vasodilator. PURPOSE: To determine what effects Arginine, a vasodilator, had on blood lactate removal after …

Comparison Of Isokinetic And Jumping Knee Torques, Synyoung Li
Kinesiology Student Research - Archive
INTRODUCTION: Isokinetic movements occur at a fixed angular velocity, regardless of torque applied by the subject. Isokinetic testing has been correlated with field tests and clinical predictions such as recovery from surgery. Peak torque at a given angular velocity is the most commonly measured variable. Although isokinetic tests are correlated with field tests such as the vertical jump, there is little research comparing the same variables. Three-dimensional motion capture systems can accurately model a subject’s movement. Software then models virtual skeletons based on the anatomical markers captured by the camera system. The virtual reconstruction of the subject provides kinetic and …

The Aerobic Capacity Of Physically Disabled College Basketball Athletes, Kelsea Bruton
Kinesiology Student Research - Archive
INTRODUCTION: Aerobic Capacity, otherwise known as maximal oxygen consumption, is the highest amount of oxygen consumed during maximal exercise in activities that use the large muscle groups in the legs or arms and legs combined. This occurs because as the heart becomes conditioned to breathing harder and more often, the heart muscle begins to hypertrophy. As the heart muscle hypertrophies, the muscle becomes stronger, allowing more oxygen to be transported to the lungs for gas exchange. A high VO2max is beneficial for fitness because the more oxygen you can take in, the more oxygen gets delivered to working muscles (Devillard, …

The Effects Of Music On Physiological Responses During Submaximal Exercise, Adrian Benna
Kinesiology Student Research - Archive
INTRODUCTION: Studies have shown that music can have psychological effects on a person. It can affect a person’s emotions and stress levels. Other variables that can be affected by music are heart rate and rate of perceived exertion (RPE). RPE is used as a way to measure workout intensity subjectively and is usually presented in the form of Borg’s scale. Heart rate is also a good indicator of the intensity of the workout. During exercise, there is an increase in sympathetic activity because of the body’s demand for more oxygen which also increases HR. PURPOSE: The purpose of this study …

A Comparison In Physiological Responses Between Cycle Ergometer And Elliptical Submaximal Exercise, Julio Jaramillo
A Comparison In Physiological Responses Between Cycle Ergometer And Elliptical Submaximal Exercise, Julio Jaramillo
Kinesiology Student Research - Archive
BACKGROUND: The specific purpose of this research was to determine if there were any physiological differences in cycle ergometer and elliptical submaximal exercises in terms of oxygen consumption, fat and carbohydrate metabolism, blood lactate production, and the amount of kilocalories metabolized. The cycle ergometer and the elliptical are both valid pieces of exercise equipment to use when pursuing submaximal exercise. The difference in how the human body consumes oxygen, metabolizes fats, carbohydrates, and kilocalories from doing a submaximal exercise using both a cycle ergometer and an elliptical on separate occasions are to be questioned. It was hypothesized that there would …

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
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 …

The Effects Of Passive, Active, And Beta-Alanine Supplemented Recovery On Blood Lactate During Anaerobic Exercise, Tracey Hampshire
Kinesiology Student Research - Archive
INTRODUCTION: It is widely shown through experimentation and knowledge of human physiology that an active recovery following high-intensity exercise removes lactic acid (BLa) more quickly than passive recovery. Some research suggests that Beta-Alanine (BA) supplementation can decrease BLa levels following supramaximal exercise. PURPOSE: The purpose of this research was to assess whether passive, active, or Beta-Alanine supplemented recovery is more effective at lowering blood lactate accumulation following supramaximal anaerobic exercise. METHODS: Five male (M, 21.2 ±1.48 yrs, 178.25 ±6.36 cm, 85.59 ±10.30 kg) and three female subjects (F, 22 ±1.73 yrs, 164.23 ±1.50 cm, 70.9 ±12.56 kgs) at UTA volunteered …
