Gonadal hormones may predict structural bone fragility in elite female soccer player

ABSTRACT

Purpose: This study determined the impact of menstrual status on bone tissue in elite post-pubertal female soccer players over an entire season.

Methods: Fifty-one elite female soccer players participated. At baseline, forty-one were assigned to the low hormonal androgenic profile (low-HAPL) and 10 to the high hormonal androgenic profile (high-HAPL).

Results: An 8-month training program led to increased bone mineral density content (p<0.05). The low-HAPL athletes improved the Narrow neck average cortical thickness (ACT) by 1.4% and reduced the corresponding Buckling ratio (BR) by 2.6%, thus decreasing the fracture risk (p<0.05). The high-HAPL athletes decreased the Narrow neck ACT by 5.4% and increased the BR by 2.6%, increasing fracture risk (p<0.05). Differences were assigned as being “very likely beneficial” for the low-HAPL athletes, supported by very large (d=3.41) and large (d=1.58) effect sizes for the Narrow neck ACT and BR, respectively.

Conclusion: A season of soccer training has induced bone geometry improvements in adolescent females. Bone health parameters improved in the two clusters. However, high-HAPL athletes decreased its resistance to loading compare to low-HAPL athletes. Even if female players do not present clinical symptoms related to their hormonal status, sport medicine physicians should pay attention to their structural bone fragility.     

Information Literacy Instruction in an English Capstone Course: A Study of Student Confidence,Perception, and Practice

An English professor and an instruction librarian at the University of New Hampshire at Manchester felt that the college's new English Capstone course for majors provided a unique opportunity to assess the information literacy skill levels of graduating English majors. They therefore engaged in a three-year study to evaluate the IL competency of these students, to gauge their perceptions of library instruction provided during the Capstone course and throughout their academic careers, and to determine students' confidence and self-efficacy with respect to these skills. The researchers sought to determine the ways in which the IL program for English majors effectively met established IL goals and to identify areas for improvement.     

Teachers' stories: physical education teachers' constructions and experiences of masculinity within secondary school physical education

Physical education (PE) and sport have traditionally been identified by scholars as a key mechanism for the production and reproduction of a culturally esteemed ideal of masculinity, premised upon being stoic, strong, competitive, sexist and homophobic. Yet, more recent research reflects a change in valued masculinity as a response to declining cultural homohysteria. As such, this preliminary study looks to establish how PE teachers understand and construct masculinities within the educational environment. Through in-depth interviews, we find participants recognised many elements of softer masculinities, described in inclusive masculinities literature, as being performed by contemporary teenagers. This includes being emotionally open, embracing a more effeminate taste in dress and being increasingly physically tactile. However, we also found that the PE teachers have a cohort variance in their masculine values, with those socialised in sport through the 1980s showing the most orthodox and oppressive views.     

Correlations among the WISC-R,PIAT, and DAM

The WISC-R, PIAT, and DAM were examined to ascertain relationships among the three instruments. Moderate to high correlations were found when PIAT scores were compared to WISC-Rg iqs, while DAM standard scores correlated moderately with PIAT and WISC-R scores. Correlations indicate that information yielded by the PIAT may be obtained through WISC-R results, while the DAM may be tapping other abilities not adequately assessed by either of the other two measures.     

An operational definition of learning disabilities (cognitive domain) using WISC full scale IQ and peabody individual achievement test scores

An operational index of discrepancy to assist in identifying learning disabilities (LD) in the cognitive domain was derived using the Full Scale IQ, Wechsler Intelligence Scale for Children (Wechsler, 1949, and relevant subtest scores on the Peabody Individual Achievement Test (PIAT) (Dunn and Markwardt, 1970. The index was applied to all legally identified LD children (N = 60) of a Michigan county who were in the LD program (1% of the total elementary school population of 6000 children). Of the 50 males and 10 females (mean age: 9 years 2 months; mean IQ: 91), the index identified 74% and 30% respectively as may be LD in the cognitive domain. This comprised 67% of the 60 children, or 2/3 of 1 % of the total elementary school population. Of the 67% may be LD children, 93% had discrepancy low PIAT subtest scores in Reading Recognition, 88% in Reading Comprehension, 83% in Spelling, and 52% in Arithmetic. Considerable caution should be exercised when classifying children, especially females, as LD.
