Tapering for Strength-Power Individual Event and Team Sport Athletes

The overall purpose of this dissertation was to address mechanistic and performance changes following a peaking phase in individual event and team sport strength-power athletes. This purpose was addressed by conducting 4 separate investigations with track and field athletes, volleyball athletes, and a national level weightlifter. The following are the primary findings from these investigations. Division I collegiate throwers increased competition throwing performance, jumping performance, and preserved muscle architecture characteristics following an overreach and taper. There were moderate decreases in division I female collegiate volleyball athlete’s vastus lateralis muscle thickness with no statistical changes in jumping performance following a taper with no prior overreach in. There were moderate to very large differences in countermovement jump height supercompensation during the peaking phase in favor of the returners over the new players on a similar team of female volleyball athletes. Changes in serum concentrations of inflammatory, hypertrophic and endocrine markers corresponded with alterations in training volume-load and partially explained changes in jump, dynamic mid-thigh pull, and weightlifting performance following multiple competition phases in a national level weightlifter. Additionally, vastus lateralis cross-sectional area can be maintained following a competition phase in a high level weightlifter provided large changes in body mass are not attempted close to competition. The findings of these investigations support the use of overreach and tapering for strength-power athletes and provide an underlying biochemical, morphological, and biomechanical basis for the observed changes in performance

Race, Social Disorganization and Delinquency

The overrepresentation of racial and ethnic minorities in crime has been an issue of debate. Some evidence, however, has shown that racial differences in offending are largely accounted for by economic disadvantage. Using data from the National Longitudinal Study of Adolescent Health (n = 4,290), the relationship between race and delinquency was examined looking at social disorganization factors. It was hypothesized that there would be racial and ethnic differences in delinquency and that these differences would be accounted for by social disorganization factors, specifically collective efficacy and economic disadvantage. The results show that compared to White adolescents Hispanic adolescents have increased odds of nonviolent and violent delinquency, and Black adolescents have increased odds of violent delinquency. Contrary to expectations, social disorganization factors did not account for the racial and ethnic differences in delinquency. Unexpectedly, higher levels of collective efficacy actually increased the odds of violent delinquency

Efficacy of Partial ROM Squat in Maximal Strength Training

Eighteen well trained males (1RM Squat: 150.57 ± 26.79 kg) were assigned to two groups: full ROM training (control) and full ROM with partial ROM training (CP) for the seven-week training intervention. There was a significant time effect (

Austin Owen Lecture: Litigating the Holocaust

The Austin Owen Lecture was established in honor of the Honorable Austin E. Owen through the generosity of his daughter, Dr. Judith O. Hopkins, W\u2774, and son-in-law, Dr. Marbry B. Hopkins, R\u2774. The Honorable Austin E. Owen attended Richmond College from 1946-47 and received his law degree from the University of Richmond School of Law in 1950. During his distinguished career, Judge Owen served as an Assistant U.S. Attorney for the Eastern District of Virginia; a partner in Owen, Gray, Rhodes, Betz, Smith and Dickerson; and was appointed Judge of the Second Judicial Circuit of Virginia where he served until his retirement in 1990. Professor Michael J. Bazyler presented this address at the Seventh Annual Austin Owen Lecture on April 12, 1999, at the University of Richmond School of Law

Comparing the Cost Effectiveness of a Celiac Disease Panel to a Testing Cascade

Recent reductions in healthcare funding in the United States has pressured clinical laboratories to provide the same quality of diagnostic testing with fewer resources. Testing cascades have been developed to assist in the diagnosis of various illnesses, which use fewer tests and subsequently reduce costs. However, the cost effectiveness of a celiac disease (CD) testing cascade compared to a panel is currently unknown. Therefore, the purpose of this study was to determine if a CD testing cascade was equivalent to a panel in identifying patients deemed likely for CD, and to compare their cost effectiveness in a sample of symptomatic patients from Northeast Tennessee. A retrospective analysis using a CD testing cascade was performed on 933 outpatient samples referred to our laboratory from 2012 to 2017 with a request for a celiac disease serology panel. The seroprevalence of CD for the panel and the cascade were the same in this population (1.82%, 95% binomial confidence interval: 1.06% to 2.90%). The total cost of the CD cascade was 268% less than the cost of the panel resulting in a savings of $44,705, which translates to a savings of$47.92/patient. Based on these findings, we recommend utilization of the cascade to identify patients with likely CD. In the future, creative use of novel testing strategies can have significant contributions to healthcare reform and afford patients more cost-effective clinical diagnostic testing
