Show moreThe purpose of this study was to examine teacher perception of student school meal preferences in an elementary school setting. This was a cross-sectional mixed-methods study that is part of a larger study to develop a nutrition education program for elementary school children. Focus groups and surveys were administered to faculty at a charter school in downtown Orlando to gain insight into the types of food offered at school and student response to these food items. All members of the faculty were invited to participate in the study, and seven teachers volunteered to take part in this study. Focus groups were recorded using tape recorders; they were then transcribed verbatim and coded independently by two research assistants. Results of this study showed that according to members of faculty, overall, the food served in school during breakfast and lunch is of poor quality. Portion sizes were acceptable according to participants, however, there is still too much food is being wasted. The students do not respond well to breakfast or lunch, which has adversely affected the academic performance of students as well as their classroom behavior due to hunger and low energy levels. It was also noted that older children expressed interest in learning about topics pertaining to nutrition. This study is the first stage of a larger initiative to develop nutrition education programs and to encourage conversation regarding school meal reform, especially as it pertains to those individuals of low socioeconomic status. The implications for this study could be beneficial for a wide-range of children who attend school on a daily basis.

Title: SHORT TERM EXAMINATION OF PHYSICAL ACTIVITY AND SLEEP QUALITY WITH CHILDREN WITH AUTISM SPECTRUM DISORDER.
Creator: Barnes, Demani Barak, Garcia, Jeanette M., Fukuda, David H., University of Central Florida
Abstract / Description: Children diagnosed with Autism Spectrum Disorder (ASD) may not be meeting the recommended amounts of physical activity (PA) or obtain a sufficient amount of sleep, however, few studies have objectively compared PA, sedentary behavior, and sleep quality between typically developing (TD) youth, and youth with ASD. Therefore, the purpose of this study was to compare levels of PA, sedentary behavior, and sleep quality between youth with ASD and TD youth. Twenty-three children with ASD and 12 TD...
Show moreChildren diagnosed with Autism Spectrum Disorder (ASD) may not be meeting the recommended amounts of physical activity (PA) or obtain a sufficient amount of sleep, however, few studies have objectively compared PA, sedentary behavior, and sleep quality between typically developing (TD) youth, and youth with ASD. Therefore, the purpose of this study was to compare levels of PA, sedentary behavior, and sleep quality between youth with ASD and TD youth. Twenty-three children with ASD and 12 TD children wore the Actigraph GT9X accelerometer over seven days and nights to assess activity and sleep. Youth with ASD had significantly greater levels of sedentary behavior (p=.02), and had less sleep efficiency compared to TD youth (p=.0001). Additionally, TD youth were more likely to achieve the recommended levels of PA compared to youth with ASD (p=.003). Results suggest that youth with ASD have poorer health habits compared to TD youth. Interventions should be developed to target health behaviors in youth with ASD.

Show morePURPOSE: The purpose of this study was to examine the effect of a modified judo training program on psychosocial health in both typically developing (TD) and children with Autism Spectrum Disorder (ASD) using a mixed-methods approach. METHODS: The sample consisted of 5 children with ASD and 5 TD children (age=8-11yrs) who participated in 10 sessions of a modified judo program during their typical physical education time for school. Psychosocial factors (enjoyment, perceived competence, benefits of PA) were assessed at baseline and post intervention, with completion of all measures dependent upon the level of comfort expressed by the participant. At the end of the program, children took part in focus group discussions centered around their experience with the program, while key school staff participated in semi-structured interviews based on their observations of the program. All focus group discussions and interviews were audio-recorded and transcribed verbatim. RESULTS: Quantitative results for pre and post psychosocial measures showed no significant differences existed between PA self-efficacy (p=.99), PA enjoyment (p=.6), and barriers to PA (p=.27). Qualitative results revealed that the majority of the participants found the program to be enjoyable, with partner centered activities being particularly fun. Suggestions for improvement included increasing the duration and frequency of the judo classes. All children reported a desire to continue participating in the judo classes. Findings from staff interviews indicated that school staff observed improvements in psychosocial health and behavior both immediately following a judo class, and throughout the intervention period. Increased self-confidence was mentioned by all participating school staff members. CONCLUSION: Despite the lack of significant quantitative findings, psychosocial benefits were observed in both TD children and children with ASD, with all participants reporting their desire to continue with the program. Future studies should examine the psychosocial benefits in a judo-training program in larger sample of children over longer durations.

Title: ESSENTIAL COMPONENTS OF PARTICIPATION FOR AN EXERCISE PROGRAM FOR UNDERSERVED, OLDER, AFRICAN-AMERICAN FEMALES.
Creator: Meinert, Marina, Garcia, Jeanette, Valdes, Anna, University of Central Florida
Abstract / Description: Physical activity (PA) is beneficial to people of all ages and ethnicities. Regular physical activity can reduce the risk of multiple chronic diseases, improve mood and sleep and allows your body to function better overall (CDC, 2018).

Show morePhysical activity (PA) is beneficial to people of all ages and ethnicities. Regular physical activity can reduce the risk of multiple chronic diseases, improve mood and sleep and allows your body to function better overall (CDC, 2018). However, populations that are more vulnerable to adverse health risks may benefit more than others from regular physical activity. This study was designed to identify the motivating factors for physical activity in a sample of older, African-American women of lower socioeconomic status (SES). This particular subgroup was chosen because of their increased risk of obesity and cardiovascular disease due to unhealthy lifestyle factors, specifically low levels of PA. (CDC, 2017). A secondary aim of this study was to determine the essential components necessary to create a successful PA program within this population. By determining the feasibility and acceptability of a PA program to target this specific population, further PA programs can be designed to promote adoption and sustainability of PA in this high-risk population. This study consisted of 8 African-American women of lower SES at an average age of 65 and average BMI of 32 kg/m^2 . The participants volunteered to participate in an 8-week exercise program for this study. The exercise class lasted 45 minutes and consisted of light aerobics, weight training, and mobility/flexibility exercises. After the 8 weeks, the participants were given questionnaires, surveys and participated in a focus group to collect data about their experiences. The Hebni staff and exercise instructors observed that there was 100% attendance and compliance throughout the 8 weeks. They also noted that the participants had positive attitudes and stayed actively engaged throughout the classes. After reviewing the data, it was noted that the necessary components to a successful exercise program for this population was a sense of community, cultural considerations, a community and familiar setting, and a reliable and open-minded instructor. The data showed that 100% of the participants continued participating in PA outside of the program and felt less stressed after exercising. This study is unique and important in that it looks at physical activity and its motivating factors in this population versus the ample research that focuses on why this population is sedentary but offers no solution to the problem.

METHODS: The sample included 20 children (ages 8 – 17) with a primary diagnosis of ASD. The participants completed an 8-week judo program that occurred once a week for 45 minutes. Participants were instructed to complete a series of questionnaires that measured athletic self-competency, PA motivation, and PA enjoyment at baseline and at the end of the 8-week judo program. Paired t-tests were conducted to examine differences in psychosocial factors from baseline and post-judo. Additionally, correlational analyses were conducted to examine the association between the psychosocial variables and attendance during the 8-week program. RESULTS: Although increases in psychosocial factors were observed following the cessation of the judo program, these changes were not statistically significant for any of the psychosocial factors following the 8-week program. There was a significant, positive association between PA motivation and judo attendance (r=.43, p=.05), however, neither athletic competency nor PA enjoyment were correlated with judo attendance. CONCLUSION: Although not significant, improvement in psychosocial factors were observed post-judo program. Future studies should consider increasing the duration and frequency of the judo program to potentially elicit greater changes in psychosocial factors related to PA.

Show morePURPOSE: To examine differences in the forearms of rock climbers using ultrasound to measure the muscle thickness of the finger flexors. METHODS: A total of 33 participants were recruited, 22 climbers (22.23 years; 68% male) and 11 controls (21.8; 55% male). Climbers provided self-reported ratings of their climbing ability, skill level, and preferred mode of climbing (e.g. sport climbing vs. bouldering). Anthropometric measures, including body fat percentage, were measured in all participants. Ultrasound measurements were taken with the participant lying on their back on a padded table with their dominant hand supinated. Muscle thickness measurements were taken at the forearm where a peak of the forearm flexors was identified on the medial aspect of the forearm after a circumference measurement and small mark was made. The distance from the ulna and radius to the muscle-skin interface was measured, as well as echo intensity surrounding the median nerve using a third party program. RESULTS: Approximately 50% of climbers rated themselves as (")intermediate("), and the other 50% rated themselves as (")advanced(") climbers, while 77% of the 22 climbers classified themselves as primarily (")sport climbers("), and 23% classified themselves as (")boulderers("). Body fat percentages were significantly different at 19.14(&)#177;6.99 and 30.02(&)#177;7.6 for climbers and controls. Ulnar and radial muscle thickness values were significantly higher in climbers, 4.23(&)#177;.39and 2.32(&)#177;.39, respectively, and 3.61(&)#177;.6 and 1.84(&)#177;.31 in controls (p(<).001). No differences in echo intensity were observed between climbers and non-climbers. DISCUSSION: The findings suggests that there are differences in flexor muscle thickness observed in earlier stages of rock climbing. Echo intensity of the flexor muscles were also measured, however significant variance in results warrants further investigation. Future studies should consider larger samples to better determine differences among muscle thickness and echo intensity across climbing abilities and mode of climbing, thus allowing for more specific training programs to be developed at each phase of training.

The sample participated in an 8-week judo program (45 minutes, 1x week), with measures taken at baseline and at the end of the 8-weeks. In order to assess activity levels and sleep quality, participants were instructed to wear Actigraph GT9X Accelerometers for 7 days and nights. In order to assess behavioral changes, parents were given the ABC survey to fill out at baseline and post-intervention. Non-parametric paired t-tests were conducted to compare differences in behaviors, MVPA, SB, and sleep quality (i.e. sleep efficiency, total sleep time, number of awakenings, and wake after sleep onset) pre and post judo. RESULTS: Results indicated there was a strong negative correlation (r= -0.632) with inappropriate behaviors and the number of classes attended. Participants also spent a significantly greater percentage of time in daily MVPA (8% vs 4%, p=0.05) following the program. There was a significant increase in total minutes of sleep duration (572.56 vs 333.8, p=0.008) following the program, and although not statistically significant, a trend existed for improved sleep efficiency (92% vs 88%, p=0.1). CONCLUSION: Despite no significant differences in ABC scores pre and post-judo, a strong association between class attendance and lower ABC scores were observed, along with improvements in MVPA and sleep quality. Future studies should include larger samples of youth with ASD, over a longer intervention period.

Show moreChildren diagnosed with Autism Spectrum Disorder (ASD) often have increased levels of stress, leading to dysregulated production of cortisol. Elevated levels of cortisol have numerous known adverse health consequences, and therefore, interventions should be established to help attenuate cortisol production. As judo combines physical activity and mindfulness practice, it may aid in stress reduction and decreased levels of cortisol. Purpose: To examine the effects of a 10-week judo program on stress reactions and salivary cortisol levels in youth with ASD. Methods: 20 children with ASD participated in the 10-week judo program. Changes in acute (before and after one judo session) and chronic salivary cortisol levels were assessed at baseline and post intervention. Parents of participants were asked to complete the Stress Survey Schedule (SSS) to determine severity of stress reactions. The SSS consists of 10 subscales: changes, anticipation, unpleasant, positives, food related, rituals, social/environmental, sensory/personal, fears, and life stressors. Sleep quality was assessed via Actigraph GT9X accelerometers over a 7-day period at baseline and post-intervention. Paired samples t-tests were used to determine differences SSS pre/post-intervention. Repeated measures ANOVA was conducted to determine differences and in cortisol levels before and after one judo session and pre and post-intervention. Spearman correlations were used to determine correlations between sleep quality and subscales of the SSS. Results: Although not statistically significant, a trend was noted indicating a decrease in cortisol levels following one judo session (p=.057). Nonsignificant reductions in the subscales (")changes (p=.14)(") and (")unpleasant (p=.12)(") of the SSS were also observed. Conclusion: Acute changes in cortisol levels may be seen following one session of judo. Subscales of parent-reported questionnaire may also show improvements following 10 weeks of participation in a judo program.

Purpose: The purpose of this study is to examine the moderating effect of MT on the effect of listening to music during exercise. Methods: The current study used a counter-balanced design, utilizing a mixed-methods approach. Thirty-one recreationally-active individuals (22.13 (&)#177; 2.11 yrs, 1.73 (&)#177; .10 m, 75.68 (&)#177; 14.67 kg, 42.89 (&)#177; 5.31 mL(&)#183;kg(&)#183;min-1; 65.5% males) were recruited for this study. Participants completed an initial visit to complete a MT questionnaire and create a personalized music playlist of at least 15 songs. Participants completed two familiarization trials and a VO2max test on the treadmill, all on separate days. The experimental trials consisted of two separate conditions: 1) no music (NM); and 2) self-selected music (SSM). For each experimental trial, participants performed a time-to-exhaustion (TTE) run at 80% of their VO2max, separated by at least 48 hours, followed by a post-study interview. Pearson product-moment correlations were used to investigate relationships between performance variables and MT. Moderated regression analysis was used to determine a potential order effect, as well as a potential moderating effect of MT on change in performance between NM and SSM groups. Linear regression analysis was used to determine a potential relationship between MT and change in performance between NM and SSM groups. An alpha level of p ? 0.05 was used to determine statistical significance. All qualitative data from post-study interviews was transcribed, coded, and categorized into primary themes. All statistical analyses was conducted via the Statistical Package for Social Science (SPSS) software for Windows version 21 (SPSS Inc., Chicago, IL). Results: Averages were calculated for MT (156.39 (&)#177; 9.38), TTESSM (14.18 (&)#177; 4.79 minutes), and TTENM (12.23 (&)#177; 5.24 minutes). Correlations were found between VO2max and TTESSM, TTENM, and MT (r = 0.390, p = 0.030; r = 0.519, p = 0.003; r = 0.404, p = 0.024; respectively). Moderated regression analysis revealed a non-significant interaction between MT, music, and order, indicating no order effect (? = -0.416, p = 0.735). Independent samples t-tests revealed no significant difference in MT, performance, or VO2maz between groups of participants who received music first or music second, indicating no effect of order (F = 0.388; p = 0.538; F = 0.537; p = 0.470; F = 0.070; p = 0.794; respectively. Moderated regression analysis, via linear regression, determined no significant moderating effect of MT on the change in performance between trials (?TTE) (F (3, 58) = 0.958, r = 0.217, p = 0.498). Linear regression, however, revealed a significant main effect of MT, indicating an inverse relationship between MT and ?TTE (F (1, 29) = 4.417, r = -0.634, p = 0.044). Discussion: The results from the current study indicate that greater levels of MT were associated with less change between the two performance trials, however, there were no significant relationships between MT or performance with self-selected music. This finding suggests that individuals with greater MT may demonstrate consistent patterns of performance, irrespective of the presence of external factors. Understanding the effects of MT and how external and internal stimuli affect performance may allow exercise professionals to tailor their training or rehabilitation programs to each individual, therefore increasing exercise performance and adherence.

Show moreThe federal reimbursable meals offered in American school cafeterias have recently been revised with improved nutrition standards yet may not meet the needs of student athletes who require additional energy intake. While many epidemiological studies report high numbers of adolescents who are overweight or obese, there are close to eight million high school students involved in interscholastic sports(-)more now than ever before. Therefore, the purpose of this research is to establish participation rates in the federal school meals programs in a local Central Florida school district between athlete and non-athlete high school populations. Additionally, the study aimed to establish athlete and non-athlete participation rates in the federal free/reduced lunch program and determine the average number of hours spent in physical activity between athlete and non-athletes in one week. An online questionnaire was developed to assess students' self-reported energy intake and energy expenditure through sport participation and physical activity acquired during leisure time. Results of the study revealed no significance difference in federal school breakfast or lunch consumption rates between athletes and non-athletes. The study also revealed similar participation rates in the free and reduced lunch program between athlete and non-athletes when purchasing school lunches. Additionally, while non-athletes reported more average hours acquiring physical activity in their leisure time than athletes did, athletes accrued more average hours of overall physical activity due to time spent in interscholastic sport practice. Lastly, results determined significant differences in Body Mass Index (BMI) with athletes having lower BMIs than non-athletes. If meals policies evolve to be more accurately reflective of energy intake needs of athletes and non-athletes, school meals could appropriately fuel student performance in the classroom, the athletic field, and beyond.

Show morePURPOSE: To compare potential differences in mechanical and physical characteristics of knee flexors and extensors in collegiate male soccer players following different warm up protocols.METHODS: Sixteen collegiate male soccer players (20.33 (&)#177; 1.33 years, 176.97 (&)#177; 6.72 cm, and 78.43 (&)#177; 7.42 kg) participated in this study. A small sided games warm up (SSG), a dynamic warm up (DYN), and a plyometric warm up (PLY) were completed using a randomized crossover design. Tensiomyography (TMG) was used to assess contraction time (Tc), delay time (Td) and maximal displacement (Dm) of the rectus femoris (RF) and biceps femoris (BF) of both legs before (PRE) and after (POST) each warm up. POST assessment included: TMG of the RF and BF, countermovement jump height (CMJ-h), CMJ flight time (CMJ-ft), 20m sprint time (20m), T-test time, and sit and reach (SR) distance. All TMG measures were analyzed using a three-way [condition (&)#215; time x leg] analysis of variance (ANOVA). All performance variable data were analyzed with a repeated measures ANOVA.RESULTS: There was no difference between warm up protocols for T-test, CMJ-h, or CMJ-ft. 20m significantly improved following SSG (p=0.020) compared to DYN and PLY. SR was significantly greater following PLY (p=0.022). Three-way ANOVA did not reveal a significant interaction for any of the measured TMG variables. However, main effects of time were seen PRE to POST for BF-Tc (p=0.035), RF-Td (p(<)0.001) and BF-Td, (p=0.008) and a main effect of condition was seen for RF-Tc (p=0.038).CONCLUSION: Warm-up specific improvements were demonstrated in sprint speed and flexibility measures following SSG and PLY, respectively. While no differences were shown between the examined protocols, the present study revealed PRE to POST changes in certain TMG measures (RF-Td, BF-Td, and BF-Tc) following a warm up in male collegiate soccer athletes.

Show moreThis dissertation is divided into three separate, related, naturalistic, quasi-experimental research studies, all using data from two kindergarten classes at Gator Elementary, a public Title I elementary school in Sunshine District in Central Florida. Each of these studies tested hypotheses that kindergarten children, especially those from low socioeconomic backgrounds, will show greater gains in receptive vocabulary, executive function, and academic achievement when purposeful play is used as a pedagogical approach than similar children in typical, contemporary kindergarten classrooms. The first study explored the effects of play-based and contemporary pedagogical approaches on students' receptive vocabulary using the PPVT-4, the second explored students' executive functions using the BRIEF2, and the third explored students' movements using Actigraph GT9X Link accelerometers. All three studies analyzed these data in relation to students' academic achievement as measured by i-Ready Diagnostic assessments. Statistically significant differences were detected in students' receptive vocabulary and reading growth as well as statistically significant differences in students' executive function health as reported by teachers and reading and math academic growth by classroom conditions. A strong association between receptive vocabulary and reading performances was revealed alongside strong negative correlations between levels of executive function concern and reading performance. No statistical differences in math growth between classrooms were found, although there was a moderate effect size, and less of an association between math performance and executive function presented. While strong correlations between academic achievement and total movement by day or movement types were revealed, these associations were inconsistent. Nor were there significant differences in movement by classroom conditions, although there was a moderate effect size suggesting some differences in movement by condition. The findings from this dissertation, while limited, point to a bourgeoning area of research connecting neuroscientific findings with developmentally appropriate practices to explore effective interventions to increase educational equity for vulnerable students.
