Basketball’S Forgotten Experiment: Don Barksdale And The Legacy Of The United States Olympic Basketball Team, Chad R. Carlson May 2010

Basketball’S Forgotten Experiment: Don Barksdale And The Legacy Of The United States Olympic Basketball Team, Chad R. Carlson

Chad Carlson

The 1948 United States Olympic basketball team has largely been fotgotten in the annals of American history despite taking a major step toward racial integration in American sports. Don Barksdale, the first African American to represent the US on the hardwood in the Olympics, joined nine players from the American South and legendary University of Kentucky coach, Adolph Rupp - a man notoriously identified as a racist. While Barksdale experienced very little racial mistreatment during the London Olympics, the lead-up to the Games reveals America's ambiguous views on race relations. During training in the segregated states of Oklahoma and Kentucky, …

Mental Qualities And Employed Mental Techniques Of Young Elite Team Sport Athletes, Mark J.G. Holland, Charlotte Woodcock, Jennifer Cumming, Joan L. Duda Jan 2010

Mental Qualities And Employed Mental Techniques Of Young Elite Team Sport Athletes, Mark J.G. Holland, Charlotte Woodcock, Jennifer Cumming, Joan L. Duda

Jennifer Cumming

Research on the psychological characteristics of elite performers has primarily focused on Olympic and World champions; however, the mental attributes of young developing and talented athletes have received less attention. Addressing this, the current study had two aims: (a) to examine the perceptions held by youth athletes regarding the mental qualities they need to facilitate their development and (b) to investigate the mental techniques used by these athletes. Forty-three male youth rugby players participated in a series of focus groups. Inductive content analysis revealed 11 categories of psychological qualities, including enjoyment, responsibility, adaptability, squad spirit, self-aware learner, determination, confidence, optimal …


The Use Of Imagery To Manipulate Challenge And Threat Appraisal States In Athletes, Sarah E. Williams, Jennifer Cumming, George M. Balanos Jan 2010

The Use Of Imagery To Manipulate Challenge And Threat Appraisal States In Athletes, Sarah E. Williams, Jennifer Cumming, George M. Balanos

Jennifer Cumming

The present study investigated whether imagery could manipulate athletes’ appraisal of stress-evoking situations (i.e., challenge or threat) and whether psychological and cardiovascular responses and interpretations varied according to cognitive appraisal of three imagery scripts: challenge, neutral, and threat. Twenty athletes (Mage = 20.85; SD = 1.76; 10 female, 10 male) imaged each script while heart rate, stroke volume, and cardiac output were obtained using Doppler echocardiography. State anxiety and self-confidence were assessed following each script using the Immediate Anxiety Measures Scale. During the imagery, a significant increase in heart rate, stroke volume, and cardiac output occurred for the challenge and …


Caffeine Does Not Augment Markers Of Muscle Damage Or Leukocytosis Following Resistance Exercise, Marco Machado, Alexander J. Koch, Jeffrey Willardson, Frederico C. Dos Santos, Victor M. Curty, Lucan N. Pereira Jan 2010

Caffeine Does Not Augment Markers Of Muscle Damage Or Leukocytosis Following Resistance Exercise, Marco Machado, Alexander J. Koch, Jeffrey Willardson, Frederico C. Dos Santos, Victor M. Curty, Lucan N. Pereira

The purpose of this study was to evaluate the effects of caffeine ingestion before a resistance exercise session on markers of muscle damage (CK, LDH, ALT, AST) and leukocyte levels. Methods: Fifteen soccer athletes completed two resistance exercise sessions that differed only in the ingestion of caffeine or a placebo preworkout. Results: CK concentration increased significantly following the caffeine session (415.8 ± 62.8 to 542.0 ± 73.5) and the placebo session (411.5 ± 43.3 to 545.8 ± 59.9), with no significant differences between sessions. Similarly, LDH concentration increased significantly following the caffeine session (377.5 ± 18.0 to 580.5 ± 36.1) …


Effect Of Different Resistance Exercise Repetition Velocities On Excess Post-Exercise Oxygen Consumption And Energetic Expenditure, Ana Critine Barreto, Alex Souto Maior, Pedro Menzes, Jeffrey Willardson, Antonio Jose Silva, Victor Machado Reis, Roberto Simão, Jefferson Novaes Jan 2010

Effect Of Different Resistance Exercise Repetition Velocities On Excess Post-Exercise Oxygen Consumption And Energetic Expenditure, Ana Critine Barreto, Alex Souto Maior, Pedro Menzes, Jeffrey Willardson, Antonio Jose Silva, Victor Machado Reis, Roberto Simão, Jefferson Novaes

Jeffrey Willardson

The excess post-exercise oxygen consumption (EPOC) consists of the excess oxygen consumed above a resting state following exercise. Performance of resistance exercise can significantly disrupt the body’s homeostasis, with the EPOC being dependent on the specific combination of prescriptive variables. Presently, the effects of different repetition velocities on VO2 and caloric expenditure during and following resistance exercise bouts have not been completely elucidated. Objective: To examine the effect of different repetition velocities on EPOC and total energetic expenditure during and following resistance exercise bouts. Methods: Twenty women (34.6 ± 5.5 years; 159 ± 4.1 cm; 55.1 ± 3.4 kg; 24±2.5 …
