Assessment of Physical Fitness of Girls on the Go Program Participants
Background: Less than half of children and adults meet physical activity recommendations. Effective interventions are especially needed to improve physical activity in African American females because they report less physical activity than their Caucasian and male counterparts.
Objective: The aim of this study was to determine the effect of the Girls on the Go after-school program on the physical fitness of its participants.
Methods: Half-mile run times for Girls on the Go participants were collected at the beginning of the program and three months later at the conclusion of the program. Only three participants were present for both runs.
Results: Due to the small sample size, no statistical analysis was conducted, but there appears to be no significant differences between pre- and post-tests. Discussion: Possible explanations for the lack of change from pre- to post-test are discussed. The results of this study could be used to inform further research
Physical Activity Behavior, Dietary Patterns, and Nutrition Knowledge of Third- and Fourth-Grade Students in Western Massachusetts
Our Extension project assessed physical activity patterns and nutrition behavior and knowledge in elementary school students in a low-income community. Dietary patterns were similar to many large-scale studies, which have shown a trend of lower fat consumption; however, these children were unfamiliar with certain nutrient terms and categories. Most physical activities were performed in PE classes; however, community organizations and family played important roles. This survey provides a basis of children\u27s nutrition knowledge and physical activity behavior. From this project we plan to develop appropriate nutrition and physical activity programs for children of similar age and socioeconomic status

Micronutrient supplement intakes among collegiate and masters athletes: A cross-sectional study
ObjectiveIn our cross-sectional study, we evaluated micronutrient supplementation intake among Collegiate and Masters Athletes.MethodsWe conducted a cross-sectional study to assess micronutrient supplementation consumption in Collegiate and Masters Athletes, comparing sex and sport classification within each respective group. Micronutrient supplement consumption data were measured using a Food Frequency Questionnaire. A two-way analysis of variance was used to explore the differences among Collegiate and Masters Athletes' supplement intakes of the following vitamins and minerals: vitamins A, B6, B12, C, E, D, and calcium, folate, iron, magnesium niacin, riboflavin, selenium, thiamine, and zinc. When significant differences were found, a Bonferroni post hoc test was performed to identify specific group differences. The significance level was set a priori at p < 0.05.ResultsA total of 198 athletes (105 females and 93 males) were included in the study. Participants were 36.16 ± 12.33 years of age. Collegiate male athletes had significantly greater vitamin A [1,090.51 ± 154.72 vs. 473.93 ± 233.18 mg retinol activity equivalents (RAE)/day] (p < 0.036), folate [337.14 ± 44.79 vs. 148.67 ± 67.50 mcg dietary folate equivalents (DFE)/day] (p < 0.027), and magnesium (65.35 ± 8.28 vs. 31.28 ± 12.48 mg/day) (p < 0.031) intakes compared to Collegiate female athletes. Collegiate CrossFit Athletes (940.71 ± 157.54 mg/day) had a significantly greater vitamin C intake compared to Collegiate General Athletes (156.34 ± 67.79 mg/day) (p < 0.005), Collegiate Triathletes (88.57 ± 148.53 mg/day) (p < 0.027), Collegiate Resistance Training Athletes (74.28 ± 143.81 mg/day) (p < 0.020), and Collegiate Powerlifters (175.71 ± 128.63 mg/day) (p < 0.044). Masters females had significantly greater calcium intakes compared to Masters males (494.09 ± 65.73 vs.187.89 ± 77.23 mg/day, respectively) (p < 0.002). Collegiate Runners (41.35 ± 6.53 mg/day) had a significantly greater iron intake compared to Collegiate Powerlifters (4.50 ± 6.53 mg/day) (p < 0.024). Masters Swimmers (61.43 ± 12.10 mg/day) had significantly greater iron intakes compared to Masters General Athletes (13.97 ± 3.56 mg/day) (p < 0.014), Masters Runners (17.74 ± 2.32 mg/day) (p < 0.03), Masters Triathletes (11.95 ± 3.73 mg/day) (p < 0.008), Masters CrossFit Athletes (15.93 ± 5.36 mg/day) (p < 0.043), Masters Rowers (9.10 ± 3.36 mg/day) (p < 0.003), and Masters Cyclists (1.71 ± 9.88 mg/day) (p < 0.011). Masters Powerlifters (47.14 ± 9.65 mg/day) had significantly greater zinc intakes compared to Masters General Athletes (9.57 ± 2.84 mg/day) (p < 0.015), Masters Runners (10.67 ± 1.85 mg/day) (p < 0.017), Masters Triathletes (10.24 ± 2.98 mg/day) (p < 0.020), Masters Rowers (9.33 ± 2.68 mg/day) (p < 0.013), and Masters Cyclists (1.43 ± 7.88 mg/day) (p < 0.019). There were no other significant differences among the other micronutrient supplement intakes between the sexes or among the sport classification.ConclusionWe reported significant differences among female and male Collegiate and Masters Athletes. Additionally, we reported significant differences among Collegiate and Masters Athletes sport classifications. Further research should examine both dietary and micronutrient supplement intake among Collegiate and Masters Athletes to examine the extent that athletes exceed the Recommended Dietary Allowances (RDA), and the potential effects on health and performance
Magnesium Intake in the Mediterranean Diet
The Mediterranean Diet (MedDiet) is a nutritional pattern native to many cultures within the Mediterranean Basin. The diet is composed of fruits, vegetables, fish, eggs, fermented dairy, grains, poultry, and minimal consumption of red meats such as lamb and beef. The diet encourages the consumption of extra virgin olive oil and moderate red wine for those who consume alcohol. The diet does not incorporate processed foods and sugary beverages. The MedDiet is rich in many micronutrients and has a healthful fatty acid profile (primarily mono- and polyunsaturated fats, with low amounts of saturated fats). The diet is rich in foods with high magnesium content, such as leafy green vegetables, nuts, seeds, and some lesser magnesium-rich foods (e.g., fish). The MedDiet is associated with reduced incidence of several diseases such as cardiovascular disease, cerebrovascular disease, neurodegenerative disease, metabolic syndrome, and type 2 diabetes mellitus. Magnesium intake has been shown to play a prominent role in the prevention and management of many of these diseases, with some of the disease-preventing capacity of the MedDiet likely caused by its high magnesium content. Those making nutritional recommendations in line with the concepts of MedDiet should particularly encourage the consumption of foods high in magnesium
The effects of the HEALTHY study intervention on middle school student dietary intakes
<p>Abstract</p> <p>Background</p> <p>The HEALTHY study was designed to respond to the alarming trends in increasing rates of overweight, obesity, and type 2 diabetes mellitus in youth. The objective of this analysis was to examine the effects of the HEALTHY study on student self-reported dietary intakes (energy, macronutrients and grams consumed of selected food groups).</p> <p>Methods</p> <p>HEALTHY was a cluster-randomized study in 42 public middle schools. Students, n = 3908, self-reported dietary intake using the Block Kids Questionnaire. General linear mixed models were used to analyze differences in dietary intake at the end of the study between intervention and control schools.</p> <p>Results</p> <p>The reported average daily fruit consumption was 10% higher at the end of the study in the intervention schools than in the control schools (138 g or approximately 2 servings versus 122 g, respectively, p = 0.0016). The reported water intake was approximately 2 fluid ounces higher in the intervention schools than in the control (483 g versus 429 g respectively; p = 0.008). There were no significant differences between intervention and control for mean intakes of energy, macronutrients, fiber, grains, vegetables, legumes, sweets, sweetened beverages, and higher- or lower-fat milk consumption.</p> <p>Conclusion</p> <p>The HEALTHY study, a five-semester middle school-based intervention program that integrated multiple components in nutrition, physical education, behavior change, and social marketing-based communications, resulted in significant changes to student's reported fruit and water intake. Subsequent interventions need to go beyond the school environment to change diet behaviors that may affect weight status of children.</p> <p>Clinical Trials Registration</p> <p><a href="http://www.clinicaltrials.gov/ct2/show/NCT00458029">NCT00458029</a></p
School factors as barriers to and facilitators of a preventive intervention for pediatric type 2 diabetes
School-based interventions are essential to prevent pediatric obesity and type 2 diabetes. School environmental factors influence implementation of these interventions. This article examines how school factors acted as barriers to and facilitators of the HEALTHY intervention. The HEALTHY study was a cluster-randomized trial of a multicomponent intervention implemented in 21 schools. Interview data were analyzed to identify barriers and facilitators. Barriers included teacher frustration that intervention activities detracted from tested subjects, student resistance and misbehavior, classroom management problems, communication equipment problems, lack of teacher/staff engagement, high cost and limited availability of nutritious products, inadequate facility space, and large class sizes. Facilitators included teacher/staff engagement, effective classroom management, student engagement, schools with direct control over food service, support from school leaders, and adequate facilities and equipment. Contextual barriers and facilitators must be taken into account in the design and implementation of school-based health interventions

The PLASMONX Project for advanced beam physics experiments
The Project PLASMONX is well progressing into its
design phase and has entered as well its second phase of
procurements for main components. The project foresees
the installation at LNF of a Ti:Sa laser system (peak
power > 170 TW), synchronized to the high brightness
electron beam produced by the SPARC photo-injector.
The advancement of the procurement of such a laser
system is reported, as well as the construction plans of a
new building at LNF to host a dedicated laboratory for
high intensity photon beam experiments (High Intensity
Laser Laboratory). Several experiments are foreseen
using this complex facility, mainly in the high gradient
plasma acceleration field and in the field of mono-
chromatic ultra-fast X-ray pulse generation via Thomson
back-scattering. Detailed numerical simulations have
been carried out to study the generation of tightly focused
electron bunches to collide with laser pulses in the
Thomson source: results on the emitted spectra of X-rays
are presented
