The Effect Of Caffeine On Anaerobic Exercise, Nelson Gonzalez

Kinesiology Student Research - Archive

Caffeine is one of the most socially acceptable performance enhancement drugs used by athletes and is one of the most widely studied ergogenic aids by sports scientists. The effect caffeine has on exercise performance is well founded, generally eliciting a dampening of perceptual response during exercise allowing the athlete to perform at a higher level. However, in comparison to aerobic performance, less research has been conducted on the ergogenic potential on anaerobic performance. Most research has been conducted through the use of the Wingate anaerobic test (WAnT), which determines anaerobic power. The WAnT requires the subject to pedal a cycle …

Correlation Between Body Fat Percentage And Maximal Exercise (Vo2max) In Collegiate Female Track Athletes, Jennifer Campos

Kinesiology Student Research - Archive

A VO2max test is used to determine the rate of utilization of oxygen which is a measure of cardiorespiratory endurance and aerobic fitness. A relative VO2max is expressed according to body weight in milliliters of oxygen consumed per kilogram of body weight per minute. The amount of body fat we maintain is dependent on diet, exercise, and heredity. Body fat can be measured by several different methods. Hydrostatic weighing determines body fat percentage through the displacement of water and is considered the gold standard in most Exercise Science Programs.

Comparison Of Body Composition, Aerobic And Anaerobic Fitness In Competitive Level Soccer Players With Regards To Position Played, Samantha Maserang

Kinesiology Student Research - Archive

Body composition can be thought of in several different terms. Body Mass Index (BMI) and body fat percentage (%bf) are the two most popular. The BMI is determined from the height and weight only, but the body fat percentage takes the age and ethnicity into account along with the actual measurement to estimate %bf. Body composition and aerobic and anaerobic fitness among high school age female soccer players has not been studied very extensively. Some studies have been conducted to examine body composition, but did not compare the positions each subject played or include the fitness level.

Among the populations with the highest obesity prevalence is women aged 60 years and older. As a Kinesiology major, I find it very important to examine the complications that arise as a result of obesity.

We know that obese individuals run the risk of developing hypertension, Type 2 diabetes, and coronary heart disease. A potential health risk associated with obesity that is understudied is cognitive functioning impairment, like dementia. Dementia is …

Lower Extremities Muscle Strength Associated With Early Signs Of Mobility Dependence Among Older Adults Age 65 Years And Older, Moshe Marko

Exercise Science - Dissertations

Background: Loss of muscle strength is evident even in apparently healthy older adults. functionally limited due to an increasing discrepancy between their own physiological capabilities (i.e. physiological impairments) and the challenges set forth by the environment. Functional limitations lead to clinical mobility disability. Clinical mobility disability is associated with physical dependence, poor quality of life, and mortality. Treatment of age-related clinical mobility disability should focus on the prevention of the condition rather than its consequences. Identifying opportunities for early screening and prevention of clinical mobility disability requires a better understanding of the functional loss prior to this medical condition. …

The Relationship Between Chronic Ankle Instability And Functional Movement Impairment In Division I Female Athletes, Akihito Tajima

Graduate Theses and Dissertations

Lateral ankle sprains are the most common injury in athletics (Denegar & Miller, 2002; Ekstrand & Tropp, 1990). In addition, the recurrent rate of ankle sprains is as high as 80% (Smith & Reischl, 1986). Repetitive ankle sprains may lead to a phenomenon known as chronic ankle instability (Hertel, 2002). It has been theorized that there are two main attributions to chronic ankle instability: mechanical and functional instability (Monaghan, Delahunt, & Caulfield, 2006). The exact mechanism of chronic ankle instability is still unclear; however, recent studies focus on multiple factors rather than single measurements, in addition to functional testing. A …
