The purpose of this Barrett Thesis Project is to review the existing literature on ACL injuries specifically regarding their risk factors, prevention, and recovery options. The content of the review has been placed into four sections: physiological factors, biomechanical factors, surgery and recovery factors, as well as training factors. Physiological factors look at static structures and their impact on ACL injuries, more specifically, the role that variations on physical structure values can have on injury incidence. Biomechanical factors focus on the ways that movement can contribute to injury and the ways that incorrect movement or unanticipated movement can have on the structures of the knee. Surgery and recovery factors look at surgical techniques that have been used to correct ACL injuries and the details of their function as well as certain surgical techniques that have differing rates of success and how they can impact re-injury and rehabilitation rates. Finally, training factors analyze techniques that can be used in both pre-injury or post-injury situations therefore, this section looks at the ways that training can minimize re-injury as well as work towards preventing the initial injury. Overall, this research review looks at how these factors come together to contribute to an ACL injury and the ways that injury incidence can be minimized. Risk factors come together in order to create an undesirable situation in which the ACL ligament ruptures. These risk factors are either physiological or biomechanical in nature. As a result of injury, certain surgical techniques can be used that impact the success of a patient. Evidence for the benefit of training factors can then be applied in order to reduce injury risk or prevent future injuries.

This review of research aimed to explore and understand the benefits of transferable life skills learned through playing sports. Life skills are internal assets, characteristics, and skills that are developed from certain experiences and are beneficial if not necessary to complete daily tasks. Life skills can further be broken down into emotional, cognitive, and social subcategories. During this review of research, it was found that participation in sports programs may enhance the acquisition or improvement of these personal assets due to the development of physical, emotional, psychological, and social aspects, which can be transferred to different areas of life, such as work, school, and family. This leads us to hypothesize that participation in sports can be beneficial when it comes to developing life skills that are used in all aspects of life. The current body of literature suggests that Youth sports should be encouraged from a young age for the obvious physical benefits and behind-the-scenes psychological benefits.

Introduction: Lateral reactive stepping is correlated with impairment in people with Parkinson’s Disease (PwPD). Despite this, there is little known of lateral stepping strategies and performance of these strategies in reactive stepping. Objective: To characterize step strategy in people with PD, characterize changes in these stepping strategies through training, and identify performance improvements in the lateral step strategies. Methods: A total of 31 PwPd who are currently at risk for falls took part in an 18-week various background reactive stepping intervention. The stepping strategies were assessed on two baseline assessments (B1 and B2) immediately followed by a 6- session step training intervention occurring over two weeks. Step strategies were again assessed immediately after training (P1) and two months later (P2). Initial outcomes were characterized step strategies, changes in step strategies, and improvement in performance of step strategies. Results: Three step strategies were established and split into two groups (no cross and cross). Changes in step strategies did not occur significantly both before and after training. Improvement in performance of the step strategies occurred at a significant amount (p=0.05) via a decrease in use of support after training occurred for any step strategies utilized. Conclusion: Step strategies were characterized, and performance of strategies was improved upon following the 2-week training. Lateral step strategies are defined and repeated throughout reactive step training with potential for improvement.

This research study examined a change of direction task within collegiate lacrosse players by using a 5-10-5 agility drill to determine if the presence or absence of the lacrosse stick (crosse) affected change of direction ability. A literature review assessed the angle-velocity tradeoff, optimal ways to perform a change of direction, and additional factors that can influence change of direction performance. 10 male participants performed 10 total trials, 5 with their stick and 5 without and timing and leg angles were measured. There were no major differences between the two conditions except for the leg angle for turn 2, as a correlation stating an increase in leg angle results in an increase in turn time was found. A case study on one of the participants was performed, which aligned with the correlation between turn 2 time and turn 2 leg angle. Overall execution of the change of direction did not align with the optimal techniques found in the literature response. Momentum leading into each turn is an influencing factor in turn time and overall time and may be the reason for the correlation between turn 2 leg angle and time.
