Description
Ruptures in the anterior cruciate ligament are a prevalent injury, particularly in young athletes. This injury is frequently treated with surgical repair utilizing autologous tissue, cadaver allografts or synthetic grafts. However there is no definitive answer on which is the best graft option. This review aims to compare clinical results of patellar tendon autograft (PT), hamstring autograft (HT), cadaver allograft and LARS synthetic ligament in ACL reconstruction. The ASU library was systematically searched for comparison studies or meta-analyses that compared or described ACL reconstruction graft options. The results of the studies were analyzed according to re-tear rate, return to pre-injury level of activity, KT-1000 laxity scores, post-operative muscle strength, International Knee Documentation Committee Score (IKDC), Lysholm score, Lachman test and donor site morbidity. Allografts showed the highest re-tear rate and increase in laxity when compared with the PT autograft and HT autograft. PT autograft provided the most stability according to the KT-1000 results. Knee extensor muscle strength was not graft dependent, but knee flexor strength decreased significantly in HT autograft patients. All grafts showed comparable results for IKDC, Lysholm scores and Lachman tests. There was increased anterior knee pain in PT autograft patients however this did not seem to have an affect on the stability or durability of the graft. The PT autograft is the best choice for individuals undergoing ACL reconstruction on the basis of lower re-tear rates and greater joint stability.

Description
Training the bench press exercise on a traditional flat bench does not induce a level of instability as seen in sport movements and activities of daily living. Because of this, many new types of equipment have been created in an attempt to induce instability, such as the COR Bench. 15 males and 7 females between the ages of 18 and 30 were recruited for the present study, which tested two forms of instability: using one dumbbell rather than two, and lifting on the COR bench compared to a flat bench. Thusly, EMG was used to measure muscle activity in four separate conditions of unilateral bench press movements: on a flat bench with one dumbbell, on a flat bench with two dumbbells, on the COR Bench with one dumbbell, and on the COR Bench with two dumbbells. Results indicated that lifting with one dumbbell compared to two dumbbells on the flat bench significantly increased muscle activity across all four muscles being analyzed (pectoralis major, p = .005; middle trapezius, p = .008; external obliques, p = .004; and internal obliques, p = .003), but lifting with one dumbbell compared to two dumbbells on the COR Bench only significantly increased muscle activity in the middle trapezius (p = .001), external obliques(p = . 032), and internal obliques (p = .001). The only muscle to exhibit a significant increase in muscle activity when going from one dumbbell on the flat bench to one dumbbell on the COR Bench was the middle trapezius (p = .010). These results imply that the COR Bench itself does not increase muscle activity as much as switching from two dumbbells to one dumbbell, regardless of the bench being used.

Description
The objective of this project was to complete an in-depth design study for the creation of a prophylactic knee brace. Background literature research analysis demonstrated that soft tissue injuries of the knee were the most prominent injuries related to the knee joint. The literature exhibited that the leading injury of the knee joint consisted of ACL lesions and meniscal tears. Utilizing the information obtained, it was determined that the objective of the knee brace was to emphasize prophylaxis of soft tissue injuries. As such, further analysis was performed in order to analyze injury mechanisms and knee joint biomechanics that would be relevant in injury prevention. An epidemiological review was also conducted regarding current braces that existed in the market today. These results were accounted for when formulating a novel design for the prophylactic device. The key feature of the brace is the implementation of shear-thickening fluid, a non-Newtonian fluid that is able to exhibit fluid-like properties at rest and solid-like properties when impacted by an outside force. This unique property is ideal for a knee brace for its enhanced adaptability and protective effects. A three dimensional digital prototype was designed in a SolidWorks software as the final result. Future endeavors consist of developing a physical prototype and conducting stress and strain analysis of the device in addition to testing its efficacy in human trials. After completion of testing and necessary revisions the goal will be to patent the technology and commercialize the brace into a device available on the public market.

Description
Physical activity has been shown to be effective in primary and secondary prevention of chronic diseases such as diabetes, cancer and cardiovascular disease (Warburton, Nicol & Bredin, 2006). Women tend to be much less active than males and are henceforth at a greater risk for developing these conditions (Biddle & Mutrie, 2008). This study addresses what impact type of physical activity in adolescence has on adult physical activity levels in the female population. Specifically, the study focuses on coordination and performance activities in adolescence, and how adult physical activity levels compare to both sedentary adolescents and adolescent endurance and ball sport athletes. Ninety-six female participants that were ages 20-29 (N=53) and 30-39 (N=43) were asked to fill out a survey about their adolescent activity levels and their current activity levels. Those participants who identified as participating in coordination and performance activity (N=43) were compared to those who were sedentary (N=14) and then further compared to those who engaged in other types of adolescent activity (N=39). It was determined that coordination and performance activities during adolescence did have a significant effect on frequency of female adult physical activity when compared to their sedentary counterparts (p=0.015). Adolescent endurance and ball sport athletes did tend to have a greater frequency of current activity in adulthood than those involved in coordination and performance activities, which was attributed to a greater frequency of practice per week in those sports. In conclusion, introducing a frequent amount of physical activity the female adolescent enjoys increases their likelihood of frequently engaging in physical activity as an adult.

Description
Research on the correlation between exercise and mental health outcomes has been a growing field for the past few decades. It is of specific interest to look at how physical activity affects psychological outcomes and it’s efficacy for treating mental health disorders. The current treatment options for depression and anxiety are not suitable for everyone and therefore there is a need for a more accessible and cost-effective form of treatment, like exercise. Furthermore, exercise as a treatment is also linked with many more health benefits. Indeed a wealth of studies have explored the relationships between exercise and depression as well as exercise and anxiety, showing exercise to be a positive predictor of mental health. The following paper will serve to: define depressive and anxiety disorders, explore the research on the effects of physical activity prescriptions on the outcomes of such disorders, create evidence-based applied recommendations for different disorders, and explore the mechanisms by which exercise mitigates symptoms to ultimately accredit the prescription of exercise as a form of treatment for mental health disorders.

Description
The purpose of this study was to use the tenets discussed in the Self-Determination Theory to explore how adolescents are motivated to engage in physical activity and examine the reasons for their participation - or lack thereof - in order to determine the influence of motives on physical activity behaviors in an adolescent population. The relative autonomy continuum of the Self-Determination Theory includes amotivation, external regulation, introjected regulation, identified regulation, integrated regulation, and intrinsic motivation. These different levels will be assessed. Participants were seventh grade students at a middle school in the Phoenix metropolitan area (n=70). The adolescents’ relative autonomy levels were assessed with a modified version of the Behavioral Regulation in Exercise Questionnaire. Individual motivational factors were measured from a modified version of the Exercise Motivations Inventory. The adolescents’ locus of causality was then measured using the Locus of Causality for Exercise Scale. Participants were asked to answer two additional questions assessing their perceived time barrier and frequency of physical activity participation. The data were scored using the scoring guidelines provided by each questionnaire after collection through a Google Form and analysis on Google Sheets. Results showed that adolescents with higher levels of identified regulation (3.88), intrinsic motivation (4.22), and locus of causality (4.67) were more likely to also engage in higher levels of physical activity. These findings could be used for future research that focuses on school-based interventions for physical activity through enjoyment so as to increase identified regulation and intrinsic motivation while shifting to a more internal locus of causality in order to increase their overall leisure-time physical activity as a way to combat the increasing rates of childhood overweight and obesity in the United States.
