Description
The gold standard for bone measurement is DXA (dual energy X-ray absorptiometry). Typically, to observe changes in bone by DXA, a minimum of a 4-month intervention is required. Serum osteocalcin (OST) (a bone formation marker) and quantitative ultrasound (QUS) of the calcaneus can be used as indicators of bone change but the sensitivity and time course of these indices to short term interventions are unknown. The purpose of this study was twofold: to compare monthly changes in OST and QUS in response to jump training and to evaluate the relationship between DXA, OST and QUS. Young women with QUS t-scores less than 1.0 were randomized into a jump training (J) (n=16) or control (C) (n=16). J consisted of a progressive routine of 1 and 2-footed jumping performed 3 days per week for 4 months. Body composition, QUS and OST were measured at baseline, and monthly for 4 months. DXA and 24-hour dietary recalls were completed at baseline and 4 months. Low attrition rate (12.5%) and high compliance (98%) with the exercise intervention was recorded. No significant correlations between QUS and OST existed. No significant differences were observed between groups at baseline in body composition or bone variables. Monthly increases in OST were observed but there were no significant differences over time between groups in any bone variables. OST and QUS may be indicative of short term bone changes but these variables were not specifically sensitive to the jumping intervention in this population of women.

Description
High Intensity Interval Training (HIIT) is a phrase quickly becoming popularized through current research due to the physical and physiological success this method of training has proven to yield in both untrained and trained individuals. There is no set definition used to describe HIIT, but it typically refers to repeated bouts of fairly brief intermittent exercise. A great deal of research outlines the benefits associated with utilizing HIIT in untrained and recreationally trained individuals. However, research on the effect HIIT has or could possibly have on the well-trained endurance athlete is limited, specifically in the sport of rowing. The purpose of this study was to analyze the effect of HIIT on VO2 peak and performance in trained rowers when compared to traditional, endurance training. It was hypothesized that HIIT would be just as effective at improving VO2 peak and performance as the endurance training protocol in well-trained rowers. A total of 20 high school female rowers participated in the study (mean ± SD; age = 16 ± 1). Baseline testing was comprised of a 2000m time-trial test on the Concept IIc Rowing Ergometer and a maximal exercise test, which was also completed on the Concept IIc Ergometer, in order to determine VO2 peak. Subjects were randomly assigned to a HIIT or endurance group for four weeks of intervention. Three days/week the HIIT group completed a 6 by 30second repeated Wingate protocol on the Concept II Ergometer at or above 100% VO2 peak, in which each 30s maximal effort was immediately followed by an active recovery of four-minutes. The endurance group completed 30 minutes of sub-maximal rowing at 65% of VO2 peak three days/week. After four weeks of intervention, post-testing took place, which was identical to baseline testing. Results from this study suggest HIIT was just as effective as endurance training at improving 2k time (mean ± SD; HIIT: 498.7 ± 23.1; Endurance: 497.5 ± 17.6). There were no significant within or between group differences in VO2 peak post-intervention (mean ± SD; HIIT: 44.8 ± 4.0; Endurance: 45.8 ± 5.6). The current study suggests four-weeks of HIIT training can yield similar adaptations in performance when compared to endurance training.

Description
Purpose: Exercise interventions often result in less than predicted weight loss or even weight gain in some individuals, with over half of the weight that is lost often being regained within one year. The current study hypothesized that one year following a 12-week supervised exercise intervention, women who continued to exercise regularly but initially gained weight would lose the weight gained, reverting back to baseline with no restoration of set-point, or continue to lose weight if weight was initially lost. Conversely, those who discontinued purposeful exercise at the conclusion of the study were expected to continue to gain or regain weight. Methods: 24 women who completed the initial 12-week exercise intervention (90min/week of supervised treadmill walking at 70%VO2peak) participated in a follow-up study one year after the conclusion of the exercise intervention. Subjects underwent Dual-energy X-Ray Absorptiometry at baseline, 12-weeks, and 15 months, and filled out physical activity questionnaires at 15 months. Results: A considerable amount of heterogeneity was observed in body weight and fat mass changes among subjects, but there was no significant overall change in weight or fat mass from baseline to follow-up. 15 women were categorized as compensators and as a group gained weight (+ 0.94±3.26kg) and fat mass (+0.22±3.25kg) compared to the 9 non-compensators who lost body weight (-0.26±3.59kg) and had essentially no change in fat mass (+0.01±2.61kg) from 12-weeks to follow-up. There was a significant between group difference (p=.003) in change in fat mass from 12-weeks to follow-up between subjects who continued to regularly vigorously exercise (-2.205±3.070kg), and those who did not (+1.320±2.156kg). Additionally, energy compensation from baseline to 12-weeks and early body weight and composition changes during the intervention were moderate predictors of body weight and composition changes from baseline to follow-up. Conclusion: The main finding of this study is that following a 12-week supervised exercise intervention, women displayed a net loss of fat mass during the follow-up period if regular vigorous exercise was continued, regardless of whether they were classified as compensators or non-compensators during the initial intervention.

Description
Previous research on gymnastics injuries has examined several differences in the types of injuries and event/location where injury is most likely to occur. This research shows that male gymnasts are more likely to have more upper body injuries compared to lower body injuries whereas female gymnasts are more likely to have lower body injuries. The majority of all gymnastics injuries are sprains that are most likely to occur during the landing phase on the floor exercise during routine performance or competition. Gymnastics injuries are also more prevalent in older gymnasts, like those at the collegiate level. However, there is limited research on the effects of limb dominance on injury occurrence in both male and female gymnasts at the collegiate level. This study was designed to examine the effect of both upper and lower body limb dominance on injury occurrence in Division I male and female gymnasts at Arizona State University during competition season. Thirty-seven subjects were recruited from the Arizona State University Men's and Women's Gymnastics teams. Athletic trainers/coaches from each team were asked to record injury incidence during the 2013 competition season from January through April. Injury type, body location, event of occurrence, and location of injury (practice or competition) were recorded along with the gymnast's upper and lower body limb dominance (right or left). Statistical analysis shows that there is a significant difference between male and female gymnasts in that female gymnasts are more likely to be injured than their male counterparts (P = 0.023). However, there were no significant findings between limb dominance and injury incidence. Limb dominance did not show any relationship with side of injury, but a trend in the data shows that right-sided dominant athletes, both upper and lower body, were more likely to be injured overall than left-sided dominant athletes. A trend in the data also shows that injury is more likely to occur on the floor exercise than any other gymnastics event for both men and women.

Description
Commitment to an activity is widely studied in leisure research. Serious Leisure Perspective (SLP) describes characteristics a committed activity participant possesses. The Psychological Continuum Model (PCM) describes the psychological process a person goes through to become committed to a leisure activity. Awareness, attraction, attachment and loyalty make of the four stages of PCM. Both perspectives have been used to describe committed leisure activity participants and commitment to organized recreational events. Research on leisure activity has yet to determine how the individual becomes loyal. Therefore, the purpose of this study is to determine the process in which recreation activity participates becomes loyal and to identify who can be labels as serious within the PCM Framework. Data was obtained from an online electronic survey distributed to participants of four U.S. marathon and half marathon events. A total of 579 responses were used in the final analysis. Path analysis determined the process in which a runner becomes committed. MANOVA is used to determine difference between leisure groups in the four stages of PCM. Results indicate that activity participants need to go through all four stages of PCM before becoming loyal. As knowledge increases, individuals are more motivated to participate. When the activity satisfies motives and becomes a reflection of their identity, feelings become stronger which results in loyalty. Socialization is instrumental to the progression through the PCM Framework. Additionally, attachment is the "bottleneck" in which all loyal activity participants my pass through. Differences exist between serious leisure groups in the attachment and loyalty stages. Those that are `less serious' are not as committed to the activity as their counterparts.

Description
The U.S. Surgeon General has recommended that all Americans engage in regular physical activity throughout the lifespan as a way to maintain and improve health and reduce the risk of developing cardiovascular disease, diabetes, obesity, or other chronic conditions. The recommendation for children is a minimum of 60 minutes of moderate and intense physical activity everyday. As children enter adolescence their level of physical activity often decreases; and active adults were typically active adolescents. More than 50% of adults that begin a physical activity program discontinue the behavior within 9 months. Interventions to increase physical activity have looked at self-esteem and self-efficacy. Locus of control (LOC) is a concept that people either view their own behavior as influencing the events around them (internal) or other events controlling their fate or destiny (external). This study looked at locus of control as a predictor of exercise adherence and future exercise patterns in children ages 6-12 in Mesa, AZ. Locus of control as measured by the Child Nowicki-Strickland Internal External (CNSIE) scale differed by gender and by physical activity group at school at post-intervention. Self-reported physical activity as measured by the Physical Activity Questionnaire for Older Children (PAQ-C) showed differences in physical activity (PA) levels by gender for baseline school PA, by age group for baseline non-school PA, by gender and age group for post-intervention school PA, and by gender only for post-intervention non-school PA. A secondary objective was to assess if the Think Healthy About Nutrition and eXercise (THANX) after school program influenced participants' LOC or PA patterns. This study found that the THANX program had no effect on LOC or PA level at any time point.

ABSTRACT Despite significant advancements in drug therapy, cardiovascular disease (CVD) is still the leading cause of death in the United States. Given this, research has begun to seek out alternative approaches to reduce CVD risk. One of these alternative approaches is Vitamin D supplementation. Current research has shown a link between Vitamin D status and CVD risk in both healthy and diseased populations. Among the possible mechanisms is a positive effect of Vitamin D on vascular endothelial function, which can be measured with noninvasive techniques such as flow-mediated dilation (FMD) of conduit vessels using high-resolution ultrasound. This dissertation is comprised of two studies. The first examines whether Vitamin D supplementation can improve FMD in older adults within a time period (two weeks) associated with peak increases in plasma Vitamin D concentrations after a single-dose supplementation. The second examines the effect of Vitamin D supplementation in people with Rheumatoid Arthritis (RA). The reason for looking at an RA population is that CVD is the leading cause of early mortality in people with RA. In the first study 29 Post-Menopausal Women received either 100,000 IU of Vitamin D3 or a Placebo. Their FMD was measured at baseline and 2 weeks after supplementation. After 2 weeks there was a significant increase in FMD in the Vitamin D group (6.19 + 4.87 % to 10.69 + 5.18 %) as compared to the Placebo group (p=.03). In the second study, 11 older adults with RA were given 100,000 IU of Vitamin D or a Placebo. At baseline and one month later their FMD was examined as well as plasma concentrations of Vitamin D and tumor necrosis factor-alpha; (TNF-alpha;). They also filled out a Quality of Life Questionnaire and underwent a submaximal exercise test on the treadmill for estimation of maximum oxygen uptake (VO2max). There was no significant change in FMD in Vitamin D group as compared to the Placebo group (p=.721). Additionally, there was no significant improvement in either plasma Vitamin D or TNF-alpha; in the Vitamin D group. There was however a significant improvement in predicted VO2max from the submaximal exercise test in the group receiving Vitamin D (p=.003). The results of these studies suggest that a single 100,000 IU dose of Vitamin D can enhance FMD within two week in older adults, but that a similar dose may not be sufficient to increase FMD or plasma Vitamin D levels in older adults with RA. A more aggressive supplementation regimen may be required in this patient population.

Description
Introduction: Several faith-based or faith-placed programs have focused on the physical dimension of wellness in efforts to improve health by increasing physical activity and improving diet behaviors. However, these programs were not designed to intervene on the mental dimension of wellness which is critical for stress reduction and health behavior change. Purpose: To evaluate the feasibility of a spirituality-based stress reduction and health behavior change intervention using the Spiritual Framework of Coping (SFC) model. Methods: This study was a quasi-experimental one group pretest posttest design. The study was a total of eight weeks conducted at a non-denominational Christian church. Participants were recruited from the church through announcements and flyers. The Optimal Health program met once a week for 1.5 hours with weekly phone calls during an additional four week follow-up period. Feasibility was assessed by the acceptability, demand, implementation, practicality, integration, and limited efficacy of the program. Analysis: Frequencies for demographics were assessed. Statistical analyses of feasibility objectives were assessed by frequencies and distribution of responses to feasibility evaluations. Limited efficacy of pretest and posttest measures were conducted using paired t-test (p <.05). Results: The Optimal Health Program was positively accepted by participants. The demand for the program was shown with average attendance of 78.7%. The program was successfully implemented as shown by meeting session objectives and 88% homework completion. The program was both practical for the intended participants and was successfully integrated within the existing environment. Limited efficacy changes within the program were mostly non-significant. Conclusion: This study tested the feasibility of implementing the Optimal Health program that specifically targeted the structural components of the Spiritual Framework of Coping Model identified to create meaning making and enhance well-being. This program may ultimately be used to help individuals improve and balance the spiritual, mental, and physical dimensions of wellness. However, length of study and limited efficacy measures will need to be reevaluated for program success.

Description
Internal and external emotion recognition is universal knowledge individuals begin to understand in early childhood. Children diagnosed with Autism Spectrum Disorder (ASD) have physiological impairments that affect their social functioning, behavior, and emotion regulation. They often have difficulty revealing true emotions as opposed to mimicked emotions, which can make social connections challenging. In this pilot study, children with high-functioning and low-functioning ASD were observed in their therapy clinic, KidzSPOT Therapy, while watching a four-minute Pixar™ video as pre and post measures. The children were their own control from pre to post-evaluation. The animated characters and situations shown in the Pixar™ videos throughout the study exhibited two specific emotions: happy and sad. For six-weeks at home, children and their caregivers were asked to watch two, four-minute PixarTM videos a week on non-consecutive days and were recorded with cellular devices. Noldus FaceReader™ was used to analyze and determine increased emotional arousal of the children from recordings sent by their caregivers as they watched the videos at home. The Circumplex Model of Affect from the Noldus FaceReader™ analysis exposed the children’s active and inactive responses. The children sought support from their caregivers and therapists as a form of validation and situational understanding. The data did not display evidence of significant correlation between variables and emotional change over the course of the study. There were many limitations to this pilot study resulting in inadequate conclusions for a whole subpopulation. These findings were limited to sample size, participant interest and age-range availability within the clinic.

For my Honor’s Project for Barrett the Honors College, I chose to research and develop an
application on the topic of Ideal Weightlifting Volume and Frequency for The Male Lifter. The
reason I decided to center my project around this topic is due to the plethora of information
available on this subject matter. However, I was more driven to pursue this subject matter due to
the lack of implementation and usage of all the relevant information and case studies offered to
us through the means of online journals, abstracts, reports, etc.
The application will be programmed using the software known as Android Studio. Inside
Android Studio, the programming language that will be utilized is Java. The goal for this
application is to gather information from the user, and with that information, create a conducive
weekly weightlifting regiment based on the wants and needs of the user. Furthermore, the
application will only create programs on a week to week basis, thus encouraging the user to
dabble with different preferences each week. Outputting the program on a week-to-week basis is
an integral logic of this program because it is my belief that if the user is given the privilege to
change their programming on a weekly basis this will allow for flexibility, adaptability, and the
pursuance of short-term goals, which is much more tangible in the onslaught of obtaining a goal.
When browsing through the app store or the internet, it is incredibly difficult to find online
programs that utilize research and scientific credibility. Many of these programs and trainers
offer quick results that are flashy and trendy, however lack any real qualitative reinforcement.
Thus, it is my mission, with my application, to create a program that is intuitive for the user, as
well as to provide scientific programming with proper citation of case studies and reports
conducted by educated individuals.
