Bone turnover is affected by exercise throughout the lifespan, especially during childhood and adolescence. The objective of this study was to investigate the impact of different sports on total and regional bone mineral density in male Brazilian adolescent athletes. Forty-six adolescents aged 10-18 years participated in the study: 12 swimmers, 10 tennis players, 10 soccer players, and 14 sedentary individuals. The athletes had engaged in physical activities for more than 10 h per week in the previous 6 months. Bone mineral density of the lumbar spine (L1-L4), left proximal femur region, and whole body was evaluated by dual-energy X-ray absorptiometry. Results showed higher mean values in the proximal femur region of tennis and soccer players (1.02 ± 0.18; 0.96 ± 0.16, respectively) than swimmers and controls (0.91 ± 0.14 and 0.87 ± 0.06, respectively) (P < 0.05). In relation to the impact of sporting activities based on bone age determination, we observed significant differences in bone mineral density at all evaluated sites at the end of puberty (16-18 years) compared with 10-12 years, with increases of 78% in the lumbar spine, 47% in the proximal femur, and 38% in the whole body. 相似文献

This is part of a new series in this regular feature regarding trends in the provision of information by health science libraries. By sharing expertise and drawing together relevant trends the series intends to serve as a road map for both health science librarians and health informatics professionals. This article shows how a medical and biomedical research library changed practices, and reassessed user needs for the COVID‐19 emergency. Discusses changes to online education (and collaborative working) to provide user‐friendly services, researcher support tailored to need and re‐visioning library space. J.M. 相似文献

Some have argued for a common language in the field of instructional design in an effort to reduce misunderstandings and simplify a multitude of synonymous terms and concepts. Others feel that this goal is undesirable in that it precludes development and flexibility. In this article we propose an ontology-building process as a way for readers to compare and analyze terms and concepts across theories. This process entails the development of categories that emerge from the literature, and the comparison of theories across categories. Such a process can reveal broader concepts that exist beyond specific theoretical terminology, differences in meanings behind common terms used by theorists, a greater understanding of the theorists’ intent, and discontinuities and gaps within the theoretical literature. 相似文献

The traditions of higher education in Russia dealing with elements of student government have been weakened in recent years, but recent research shows support among Russian students for greater involvement in activities related to their lives as students. 相似文献

The Expression of Depressive Symptomatology in Korean American Undergraduates: Sex and Generational Differences 下载免费PDF全文
Jeanett Castellanos Alberta M. Gloria Sara Cho Kim Yong S. Park 《Journal of College Counseling》2014,17(3):208-221
This study examined the influence of acculturation and perception of the university environment on the depressive symptomatology of 228 Korean American undergraduates, with a focus on sex and generational differences. Perceptions of the university environment and perceived barriers were positive predictors of depressive symptomatology in respective regression equations by sex and generation. Study limitations and counseling practice implications are discussed. 相似文献
