The load-velocity profile differs more between men and women than between individuals with different strength levels

This study aimed to determine the suitability of the load-velocity relationship to prescribe the relative load (%1RM) in women, as well as to compare the load-velocity profile between sexes and participants with different strength levels. The load-velocity relationship of 14 men (1RM: 1.17 ± 0.19) and 14 women (1RM: 0.66 ± 0.13) were evaluated in the bench press exercise. The main findings revealed that: (I) the load-velocity relationship was always strong and linear (R² range: 0.987–0.993), (II) a steeper load-velocity profile was observed in men compared to women (Effect size [ES]: 1.09), with men showing higher velocities for light loads (ES: ? 0.81 and ? 0.40 for the y-intercept and 30%1RM, respectively), but women reporting higher velocities for the heavy loads (ES: 1.14 and 1.50 at 90%1RM and 100%1RM, respectively); and (III) while the slope of the load-velocity profile was moderately steeper for weak men compared to their strong counterpart (ES: 1.02), small differences were observed between strong and weak women (ES: ? 0.39). While these results support the use of the individual load-velocity relationship to prescribe the %1RM in the bench press exercise for women, they also highlight the large disparities in their load-velocity profile compared to men.     

Political failure and the necessity for global democracy

Abstract

This paper aims to explore the changes in creative activities of young people – especially in the alternative media – in Indonesia before and after Reformasi. It begins with the story of the dynamics of a student press, from my personal experience – which I believe is a typical form of student/youth movement in Indonesia – and how the student’s life obviously depends on the political situation, the university policy, and the dynamics of the student’s life at that particular time. Reformasi caused political change and freedom but simultaneously, and ironically, placed the student press in a state of meaninglessness, such that it was painfully forced for search for new meanings to keep it contextually relevant in the new era. I end the paper describing the latest form of the alternative media scene of Indonesian youth, whose focus is dramatically shifting from ‘big’ political issues to issues of the celebration of communities and self‐existence.     

The 1936 Olympic Games in Berlin: The Response of America's Black Press

Abstract

Eighty-seven female masters swimmers ranging in age from 20 to 69 were selected for a detailed study of their body composition and physiological responses at rest and during exercise. These women were then placed into two subsets, a highly trained group and a not highly trained group, on the basis of the frequency, duration, and intensity of swimming workouts. Significant differences were detected when comparing the highly trained and not highly trained subjects on measures of weight, body density, percent fat and lean body weight (p<.05). Significant differences which favored the highly trained group were also seen when comparing these same two groups for [Vdot]_E max, [Vdot]O₂ max (1/min), [Vdot]O₂ max (ml·kg^–1·min^–1), [Vdot]O₂ max (ml·kg·LBW^–1·min^–1), O₂ pulse (ml·kg^–1·beat^–1), and O₂ pulse (ml·kg·LBW^–1). Both the highly trained and not highly trained swimmers were considerably lower in percent fat than previously reported data for normal untrained women of similar ages. In both groups, however, percent fat across age levels within each training group showed significant increases at approximately 40 years of age (p<.05). In the highly trained swimmers, [Vdot]O₂ max (ml·kg^–1·min^–1) decreased at a mean rate of about 7% per decade, while in the not highly trained swimmers the decline was approximately 8% per decade. It appears that the rate of decline in [Vdot]O₂ max in women with aging may be independent of training status.     

体育新闻侵权的法律思考

采用文献资料研究和个案调查方法，通过对两个体育新闻侵权而败诉的案件分析，认为体育新闻工作者要坚持新闻真实性原则，增强法制意识，加强自我保护；有关部门要加快立法进程，尽早出台《新闻舆论监督条例》，使媒体的新闻舆论监督工作有法可依，规范操作，防止或减少体育新闻侵权行为的再次发生。     

基于核心出版社理论的学术图书采购策略

学术图书采购是图书馆实现文献资源优化配置的前提条件,运用核心出版社理论可以充分提高学术图书的采全率和采准率。目前我国图书馆在学术图书采购方面还存在着不少误区和不足。采用现货采购以核心出版社为主、期货采购以外围出版社为主的采访模式,运用引文分析法对学术图书进行查漏补缺,可以优化馆藏资源建设,提高读者满意度。

对热应激、脑损伤与机体免疫间关系的研究

高温环境下长时间暴露或长时间、大强度运动容易导致脑组织微观结构损伤、机体免疫机能下降。损伤机制与高温、自由基、磷脂酶A2、氨基酸及NO代谢有关。高温环境下脑损伤与机能免疫机能下降之间可能存在直接关系。
