The Mental Aspect Of Human Performance, Brandon Epstein

Whittier Scholars Program

This is a project about sports psychology and the mind/body connection. There are limits to what the body can achieve on its own. With sports psychology we are now able to create opportunities for athletes and performers to reach their optimal potential. This is done by incorporating the power of the mind. If we supply ourselves with the appropriate tools and maintain unrelenting discipline, there is no limit to what can be accomplished. In this project, various mental techniques for achieving a mind/body connection are discussed, including self-talk, imagery, and brainwave manipulation. The project concludes with a weightlifting case-study, in …

The Development Of The Self-Efficacy Of Balance Scale (Sebs): Investigation Of Psychometric Properties In Female Basketball Players, Carrie Silkman Baker

Theses and Dissertations--Rehabilitation Sciences

Lower extremity injuries are the most common sports related injury. Many steps have been taken to attempt to identify individuals who might be at a higher risk for sustaining a lower extremity injury. Resource and time intensive screening techniques have been used previously to attempt to identify such individuals. However these techniques have focused heavily on postural control and landing mechanics in athletes, no psychological measure has been used to identify individuals who might be at a higher risk of lower extremity injury.

Self-efficacy of balance can be defined as how capable an individual feels he or she can balance …

Late Removal Of Titanium Hardware From The Elbow Is Problematic, Abdo Bachoura, Ruriko Yoshida, Christian Lattermann, Srinath Kamineni

Orthopaedic Surgery and Sports Medicine Faculty Publications

A retrospective review of 21 patients that underwent bone screw removal from the elbow was studied in relation to the type of metal, duration of implantation, and the location of the screws about the elbow. Screw failure during extraction was the dependent variable. Five of 21 patients experienced hardware failure during extraction. Fourteen patients had titanium alloy implants. In four cases, titanium screws broke during extraction. Compared to stainless steel, titanium screw failure during removal was not statistically significant (P = 0.61). Screw removal 12 months after surgery was more likely to result in broken, retained screws in general …

Body Mass Bias In Exercise Physiology, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

In certain physically demanding occupations, especially the military, body mass bias has substantive implications. Work physiologists have determined that despite body mass bias in the common military physical fitness tests, the larger service members were often better performers of the physically demanding occupational tasks (Bilzon et al., 2002; Lyons et al., 2005; Rayson et al., 2000). That is, they could carry more, more easily evacuate casualties, and better engage in heavy materiel handling. Yet, the smaller personnel were achieving better scores on the physical fitness tests, the results of which have significant promotion and advancement implications (Vanderburgh & Mahar , …

Effects Of Proximal Stability Training On Sport Performance And Proximal Stability Measures, Thomas Gerard Palmer

Theses and Dissertations--Rehabilitation Sciences

Proximal stability, or the ability to stabilize and actively control the spine, pelvis and trunk, has been reported to influence sport performance. Traditional training practices for the proximal segments have had little success improving sport performance. The purpose of this dissertation was to investigate the effects a sport specific proximal stability training program can have on throwing velocity and measures of muscular endurance and power which target the proximal segments of the pelvis, spine and trunk.

A stratified randomized clinical trial was implemented with a pre- to post-intervention design. Forty-six healthy, Division III collegiate female softball (n=17) and male baseball …

Strength Gains: Block Versus Daily Undulating Periodization Weight Training Among Track And Field Athletes, Keith Painter, Guy Haff, Michael Ramsey, Jeff Mcbride, Travise Triplett, William Sands, Hugh Lamont, Margaret Stone, Michael Stone

Research outputs 2012

Recently, the comparison of "periodized" strength training methods has been a focus of both exercise and sport science. Daily undulating periodization (DUP), using daily alterations in repetitions, has been developed and touted as a superior method of training, while block forms of programming for periodization have been questioned. Therefore, the purpose of this study is to compare block to DUP in Division I track and field athletes. Thirty-one athletes were assigned to either a 10-wk block or DUP training group in which sex, year, and event were matched. Over the course of the study, there were 4 testing sessions, which …

Effects Of Two Contrast Training Programs On Jump Performance In Rugby Union Players During A Competition Phase, C K Argus, N D Gill, J W Keogh, Michael Mcguigan, W G Hopkins

Research outputs 2012

Purpose: There is little literature comparing contrast training programs typically performed by team-sport athletes within a competitive phase. We compared the effects of two contrast training programs on a range of measures in high-level rugby union players during the competition season. Methods: The programs consisted of a higher volume-load (strength-power) or lower volume-load (speed-power) resistance training; each included a tapering of loading (higher force early in the week, higher velocity later in the week) and was performed twice a week for 4 wk. Eighteen players were assessed for peak power during a bodyweight countermovement jump (BWCMJ), bodyweight squat jump (BWSJ), …

Force Output Comparison Between Six U.S. Collegiate Athletic Teams., Caleb D. Bazyler, George Beckham, Howard Gray, Guy Hornsby, Ashley A. Kavanaugh, Christopher Macdonald, Satoshi Mizuguchi, Michael H. Stone, Michael H. Stone

ETSU Faculty Works

The aim of the study was to compare allometrically scaled peak force and the force at 250 ms between six U.S. collegiate sport teams using isometric mid-thigh pull. Ninety subjects performed maximum effort of isometric mid-thigh pull to measure force output. The data were averaged within the teams, and statistically compared between teams using one-way ANOVA (p=.01). Significant difference was found that men’s soccer and baseball produced higher allometrically scaled peak force, and men’s soccer, tennis, and baseball produced higher allometrically scaled force at 250 ms. The data indicates that not all sports possess similar strength characteristics because of the …

Methods: Eight adults with chronic ankle instability and eight adults with no ankle sprain history participated. Vibrotactile detection thresholds were assessed using a mechanical stimulus generator system, mounted onto an articulated microscope arm, which delivered sinusoidal vibrotactile inputs to the foot sole at three different sites: head of the first metatarsal, base of the fifth metatarsal, and the heel. Vibrotactile stimulation was delivered at a range of test frequencies that corresponded …

Fitness, Fatness, And Metformin Response, Corey A. Rynders

Human Movement Studies & Special Education Faculty Publications

We appreciate the comments of Dr. Falk and Mr. Dotan and would like to respond to their concerns. As we indicate in the discussion of our article (1), we realize that changes in maturation and body composition can affect the assessment of VO_2max. However, we do not feel that the change in VO_2peak observed in the subjects that improved VO_2peak was primarily related to a reduction in body weight.

The Effectiveness Of Injury-Prevention Programs In Reducing The Incidence Of Anterior Cruciate Ligament Sprains In Adolescent Athletes, Jeffrey Paszkewicz, Tristen Webb, Brian Waters, Cailee Welch Mccarty, Bonnie Van Lunen

Human Movement Studies & Special Education Faculty Publications

Clinical Scenario: There is a high incidence of anterior cruciate ligament (ACL) injury in adolescents participating in pivoting sports such as soccer, basketball, and handball. Most ACL injuries in athletes are noncontact injuries, with a mechanism of sudden deceleration, change in direction, or landing from a jump. These mechanisms coupled with an increase in contraction of the quadriceps have been shown as risk factors for ACL injuries. Injuries to the ACL may require surgery, a long rehabilitation, and the potential for reinjury. Studies have shown reductions in lower extremity injury rates using training protocols that focus on landing mechanics, balance …

Landing Technique Affects Knee Loading And Position During Athletic Tasks, Nelson Cortes, Steven Morrison, Bonnie L. Van Lunen, James A. Onate
