Determining The Efficacy Of Fifa 11+ In Reducing Acl Injury In Female Soccer Players, John Hallmark

Celebration of Learning

Objective-This study aims to identify the relationship between the Fifa 11+ program and the angle of valgus deformity at the knee. Background-200,000 ACL tears are reported each year. Previous studies have linked valgus motion of the knee to an increased rate of ACL injury and females exhibit a 4-6x increased risk for ACL injury. Fifa 11+ has shown promise in studies done on professional soccer teams yet remains untested in a younger population. Methods-This prospective cohort study of 300 consented female soccer players will use Noraxon as a tool for the measurement of valgus angle at the …

The Effects Of Self-Adherent Taping On Peak Inversion Angle And Eversion Moment Upon Landing During A Maximal Vertical Jump And A Depth Drop, Christopher M. Gregoire

Cal Poly Humboldt theses and projects

Ankle injuries are the most common injury in physically active adults with roughly 15% to 30% of all physical activity injuries being ankle injuries. The purpose of this study is to evaluate the effectiveness of a self-adherent ankle taping in reducing peak ankle inversion angle and peak ankle eversion moment upon landing during a max vertical jump and depth drop compared to jumping without a prophylactic ankle stabilizer.

Twelve volunteers participated in testing procedure on two separate days. Day one consisted of orientation while day two consisted of experimental data collection. The participant’s peak inversion angle and eversion moment were …

The Effect Of Tackling Training On Head Accelerations In Youth American Football, Eric Schussler, Richard J. Jagacinski, Susan E. White, Ajit M. Chaudhari, John A. Buford, James A. Onate

Rehabilitation Sciences Faculty Publications

Background: Many organizations have introduced frameworks to reduce the incidence of football related concussions through proper equipment fitting, coach education, and alteration of tackling technique.

Purpose: The purpose of this study was to examine the effects of training in a vertical, head up tackling style on the number of head accelerations experienced while tackling in a controlled laboratory situation. The authors hypothesized that training in a head up tackling technique would reduce the severity of head acceleration experienced by participants.

Design: Controlled Laboratory Study.

Methods: Twenty-four participants (11.5 ± 0.6 years old, 60.5 ± 2.2 in, 110 ± 18.4 lbs.) …
