Influence of vitamin D mushroom powder supplementation on exercise-induced muscle damage in vitamin D insufficient high school athletes

Abstract

Incidence of vitamin D deficiency is increasing worldwide. The purpose of this study was to determine if supplementation with vitamin D₂ from Portobello mushroom powder would enhance skeletal muscle function and attenuate exercise-induced muscle damage in low vitamin D status high school athletes. Participants were randomised to Portobello mushroom powder (600 IU/d vitamin D₂) or placebo for 6 weeks. Participants then completed a 1.5-h exercise session designed to induce skeletal muscle damage. Blood samples and measures of skeletal muscle function were taken pre-supplementation, post-supplementation/pre-exercise and post-exercise. Six weeks supplementation with vitamin D₂ increased serum 25(OH)D₂ by 9.9-fold and decreased serum 25(OH)D₃ by 28%. Changes in skeletal muscle function and circulating markers of skeletal muscle damage did not differ between groups. In conclusion, 600 IU/d vitamin D₂ increased 25(OH)D₂ with a concomitant decrease in 25(OD)D₃, with no effect on muscular function or exercise-induced muscle damage in high school athletes.     

The Application of a Multiple Measurement Approach to Investigate the Effects of a Dance Program on Educable Mentally Retarded Adolescents

Abstract

Little evidence exists to assess the effects of dance training on special populations. Research in this field has relied on pretest-posttest methods for gathering data. While such data gathering methods may be appropriate for particular research problems, alone they may be inadequate for broad-based, exploratory investigations of programs and effects. The present study is an example of a multiple measurement approach that uses eight measurements, in combination, to answer four research questions regarding the physical and social effects that occur when a group of educable mentally retarded adolescents is exposed to a 10-week dance program. The findings revealed that four students showed improvement in both social and physical behaviors, seven students showed improvement in either social or physical behaviors, and two students showed no improvement. There was no evidence of a “transfer effect” due to participation in the program, and some students' behaviors were affected by external factors. The authors found the approach useful for identifying multiple effects and generating hypotheses for further study.     

Selection of models in contingency tables: A reexamination

Qualitative data often need analysis using log-linear models, as pointed out by Liu and Sanders. In this article, references to the state-of-the-art literature and software packages for analyzing such data are presented. We also illustrate the two types of log-linear models and present procedures for investigating both types.     

Effects of ICT group work on interactions and social acceptance of a primary pupil with Asperger's Syndrome

The aim of this study was to ascertain whether collaborative group work on a computer, facilitated by an adult, could provide a means for a primary schoolboy with Asperger's Syndrome (AS)—moderately‐highly affected in all areas of the “triad of impairments”—to develop appropriate task‐related interactions with his peers. Data were gathered before, during, and after group work sessions. A combination of interviews and questionnaires established background data and concerns of parent and teachers. Sociometric testing of classmates was used to determine social acceptance and friendship grouping among the child's immediate peer group. During the adult‐facilitated ICT sessions an interaction process schedule (IPS) was used to record interactions of the three children involved. The results indicate moderate improvements in the child's ability to interact with his peers, both in social and task‐related contexts, as well as a raised social profile among his classmates in general. Although this was a discrete setting, the findings are encouraging and this strategy may be replicated in schools to support mainstream inclusion for children with AS.     

Explaining the academic performance of community college students who transfer to a senior institution

The academic performance of 361 community college students was investigated after their transfer to a comprehensive university. The predictor variables included personal, environmental, demographic, and pretransfer academic measures. The criterion was grade point average (GPA) at the senior institution. Analyses included moderated linear regression and a branching algorithm which forms subgroups to best explain criterion scores (AID-3). The academic pattern and performance at the community college was found to be very important to the relevance of specific factors related to the curriculum selected at the senior institution.     

Factors contributing to research excellence

What factors contribute to high-quality funded research activity in research universities? What do these institutions have in common? What management strategies do they employ to encourage funded research excellence and activity? In this period of decreased or level government spending, competition for grants among research universities becomes fierce. In order to stay competitive, it is important to know what works in research management. Preliminary research has allowed us to provide some answers and to clarify some key questions on what makes a successful research program.
