The Implementation Of Exercise For Chronic Kidney Disease And Dialysis Patients, Syed Ahmad Rizvi

Honors College Theses

While commonly known to be the organ that helps with urine production within the human body, the kidney plays one of the most crucial roles in maintaining homeostasis. When establishing all of the roles the kidney has on keeping humans healthy, there is the question of how does the body cope when a patient is diagnosed with kidney failure. One of the more common treatment options that allows the body to continue to function without a kidney is by beginning a patient on a form of dialysis. However, as with any treatment, there will always be a list of side …

Characterization Of Adult Heart Rate Responses During Recreational Skateboarding At Community Skateparks, Tyler Wiles, Daniel Kellogg, Heather Furr, Jeff A. Nessler, Sean C. Newcomer

International Journal of Exercise Science

International Journal of Exercise Science 13(2): 501-510, 2020. Youth participating in recreational skating at community skate parks attain exercise intensities and durations that are comparable with the CDC’s exercise recommendations for cardiovascular fitness for their age group. However, it is currently unclear if adults who skateboard in the same environment also achieve the recommended intensities and durations for cardiovascular fitness. Therefore, the purpose of this study was to test the hypothesis that skateboarding would elicit heart rates and durations consistent with the CDC’s recommendations for cardiovascular fitness in adults. Fifty-five subjects between ages 18-55 were recruited from six community skateparks …

Impact Of Psychological And Physical Stressors On The Exercise-Induced Immune Response In Collegiate Swimmers, Connor Alexander Kuremsky

LSU Master's Theses

Evidence suggests high-intensity exercise training increases incidence of upper respiratory infection in young-adult athletes (Spence et al. 2007). Collegiate athletes experience chronic stress, which has been shown to result in increased proportions of late-differentiated CD8+ T-cells of a dysfunctional phenotype (Bosch et al. 2009). However, many studies fail to consider possible moderators such as psychological stress and cytomegalovirus (CMV) infection. Purpose: To examine the impact of psychological stress, CMV infection, and exercise on proportions of early- and late-differentiated CD4+ and CD8+ T-cells in collegiate swimmers over a 7-month training period. Methods: Data were collected from NCAA …

Agreement Among Six Methods Of Predicting The Anaerobic Lactate Threshold In Elite Cross-Country Skiers, Sean L. Carter, Ian Newhouse

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 155-172, 2019. The anaerobic lactate threshold (LTan) is used to prescribe training intensity and measure endurance capacity. The LTan identifies a critical point where small increases in workload result in large increases in blood lactate concentration. LTan is usually predicted through visual inspection of a blood lactate (bLa) vs workload plot. Numerous other methods for predicting LTan exist, and the literature lacks a consensus regarding validity of prediction methods. The purpose of this study was to assess the agreement among visual inspection (VI), maximum distance (Dmax) and modified maximum distance (Dmod) from the lactate …
