健身运动处方锻炼对小学生身体形态、机能的影响研究

本文以小学生为实验对象，研究健身运动处方对小学生身体形态机能的影响。结果提示本实验制定的健身运动处方能不同程度地改善实验对象的心血管及肺功能，但不同处方对不同机能指标的影响不同，同一处方对同一年龄段男生与女生的影响也不同，从本实验结果看，各年龄段女生对本运动处方训练的敏感性更强。     

二次文献发表延时过程的数学模拟及其分析

二次文献发表延时过程模型的建立 ,为研究利用二次文献查新的漏检问题提供了定量化工具。文献查新 ,不仅要检索二次文献数据库 ,还要检索学科范围内近期的核心期刊和相关期刊的一次文献。它也为二次文献检索数据库建立了定量化研究方法。图 2。参考文献 1。

A nation at risk: The economic consequences of neglecting career development

Conclusion Computer-based career systems should be the focal point of popular, and effective career development initiatives which are of tremendous benefit to individuals. Such initiatives also have the potential to significantly reduce public expenditures and enhance the nation's competitive position internationally. The key lies in helping people understand that we can no longer afford to neglect the career development needs of Americans.I am most grateful for this opportunity to share my thoughts with you. I encourage you to promote the use of computer-based career systems by defining their benefits in economic terms. However, be sure you can prove your system does more than simply entertain its users, or leave them with extensive computer printouts.Phillip S. Jarvis is Manager, Careerware Research and Product Design, STM Systems Corp., Ottawa, Ontario, Canada and the author of CHOICES. This is the text of a paper presented to the Annual Conference of the Association of Computer-Based Systems for Career Information ((ACSCI) in St. Louis, Missouri on December 2, 1988.

A comparison of the anthropometric, strength, endurance and flexibility characteristics of female elite and recreational climbers and non-climbers.

There is limited information on the anthropometry, strength, endurance and flexibility of female rock climbers. The aim of this study was to compare these characteristics in three groups of females: Group 1 comprised 10 elite climbers aged 31.3 +/- 5.0 years (mean +/- s) who had led to a standard of 'hard very severe'; Group 2 consisted of 10 recreational climbers aged 24.1 +/- 4.0 years who had led to a standard of 'severe'; and Group 3 comprised 10 physically active individuals aged 28.5 +/- 5.0 years who had not previously rock-climbed. The tests included finger strength (grip strength, finger strength measured on climbing-specific apparatus), flexibility, bent arm hang and pull-ups. Regression procedures (analysis of covariance) were used to examine the influence of body mass, leg length, height and age. For finger strength, the elite climbers recorded significantly higher values (P < 0.05) than the recreational climbers and non-climbers (four fingers, right hand: elite 321 +/- 18 N, recreational 251 +/- 14 N, non-climbers 256 +/- 15 N; four fingers, left hand: elite 307 +/- 14 N, recreational 248 +/- 12 N, non-climbers 243 +/- 11 N). For grip strength of the right hand, the elite climbers recorded significantly higher values than the recreational climbers only (elite 338 +/- 12 N, recreational 289 +/- 10 N, non-climbers 307 +/- 11 N). The results suggest that elite climbers have greater finger strength than recreational climbers and non-climbers.
