Ashley Burkman, Ali Gazzola and Iryna KostirkoHS342 Due: 5/1/17Lab Final Project: VO2 MaxIntroduction:As a general population people in the United States are not as healthy as they can be. Consistently performing aerobic exercise can help to reduce disease risk and contribute to better overall health. As adults ideally we are supposed to get 30-60min of moderate aerobic exercise everyday. In reality for most people doing this even twice a week can be challenging. Exercise is especially important for overweight/obese individuals or individuals with cardiac risk factors. Those with these and other risk factors that are beginning an exercise program may first need to be evaluated for a prescribed exercise intensity.VO2 max is one factor that is used to determine an athlete’s capacity to perform sustained exercise. VO2 max is the maximum amount of oxygen that an individual is able to use during intense exercise. Having a higher VO2max allows more oxygen to reach your muscles, in turn allowing you to exercise for a longer amount of time. Therefore VO2max is a good indicator of overall fitness. Untrained individuals (most of the population) have a much lower VO2 max compared to trained individuals. Anaerobicthreshold (VT1) relates to the lactate response to incremental exercise. This corresponds to a break in the lactate accumulation graph. Like VO2 max VT1 increases with training and has been shown to be a good predictor of exercise capability/ aerobic fitness. Using a submaximal GXT to evaluate aerobic fitness and set a standard for exercise prescription allows fitness goals to be established. These goals, such as improving VO2 max, correspond to moving from a untrained state to a trained state. Thisresults in an increased ability to perform physical activity and leads to an overall increased degree of fitness. In the long run these goals lead to a better health status for the individual both physically and mentally. Specific goals: The overarching goal of this project is to improve the athlete’s VO2 max. The specific benefits that are sought to be obtained from this by the athlete include a greater ability to perform physical activities for an increased amount of time such as, running, swimming and biking as well as increasing overall physical fitness. The athlete used to be a student athlete in high school, participating in swimmingand tennis. During this time the athlete used to be able to exercise at a higher capacity when training and performing at these competitive levels. However, during the past 3 years the athlete has not trained to this same intensity level or frequency and has experienced substantial detraining. The major form of constant exercise that the athlete performs is by walking as a primary or of transportation along with the occasional use of a fitness facility for moderate intensity cardio workouts such as using the elliptical for about 20 minutes and then performing light-moderate strength exercises.
