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
This observational study explored the motivational factors for recreational cyclists participating in a charity cycling event held by a Christian based nonprofit, the Fuller Center. Participants (n=22; men: n=10; women: n=12) cycled at least one 302 mile segment of a bike ride distancing the whole West Coast (1,657 miles). The purpose of the study was to determine the motives for the cyclists' participation and to then classify those motives as intrinsic or extrinsic. A scale used to measure motivation of marathoners was transcribed to match those of the cycling participants to assess motivation. The participants were divided into 4 groups based on self-reported experience levels, and it was shown that across all types of experience levels, both intrinsic and extrinsic motivators were expressed but with greater emphasis on intrinsic factors. The most commonly indicated intrinsic motivation subcategories were life meaning, personal goal achievement, and affiliation, with affiliation being recognized by every individual. The most commonly indicated extrinsic subcategories were competition, recognition, health orientation, and weight concern. Though each rider's story was signature to the individual, the very specific religious background and philanthropic mission of the Fuller Center Bike Adventure weighed heavily into each individual's motivation alongside the classified intrinsic and extrinsic factors. Therefore, this research offered valuable data about motivation of recreational cyclists but future studies should focus on a less specific population.

Description
The purpose of this study was to analyze the effects of changing a saddle height to a scientifically recommended position on cycling economy for competitive cyclists. Participants completed one maximal effort graded exercise test and two sub-maximal 70% economy trials, one at the cyclist’s original saddle height and the second at the saddle height corresponding with a knee flexion angle of 25° at full pedal extension. Due to experimental error and equipment failure heart rate became the main performance measure and cycling economy tests were conducted at an average of 84.4% of heart rate max. The results revealed no apparent differences in performance between the recommended and original saddle height. However, 2D analysis of dynamic knee angles revealed that at the 25° knee angle condition, knee angle increased by an average of 16.1% from the static position (average dynamic knee angle = 29.02±4.61°). Dynamic measures (32.59±4.88°) taken during the original angle tests were only slightly augmented compared to the static measure (31.5±2.18°). It is possible based on this trend that a difference in performance values was not present because the change between the original angle and the experimental angle was not substantial. Additionally these findings suggest that cyclists adjust to these acute changes in saddle height by altering other kinematic variables in an attempt to find a comfortable position and perform maximally.

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.
