江西省高校竞技体育项目布局的现状分析

运用文献资料、问卷调查,专家访谈等研究方法,对江西省普通高校竞技体育的项目布局进行了系统的分析。研究发现,高水平运动员的生源数量减幅较大,相当一部分项目的发展呈现出极不稳定的态势,如田径、篮球、排球,其中,田径项目表现尤为突出,出现了严重生源危机,应引起有关部门和人员的高度重视。     

体院健美操专项学生内部动机与学业成绩的相关研究

参照北京体育大学教授张力为博士,2004年编写的由北京体育大学出版社出版的《体育科学常用心理量表评定手册》书中的内部动机量表,对健美操专项学生实施内部动机测量[1]。研究结果表明,在内部动机测量的7项指标中,不同等级成绩水平的学生在兴趣/乐趣、主观能力和压力3项指标上存在显著性的差异（P〈0.05）,其他各项指标努力、主观选择、价值/有用性和相关性不存在显著性的差异（P〉0.05）。可见,不同等级成绩学生在努力、主观选择、价值/有用性和相关性的指标上处于同一水平,而指标兴趣/乐趣、主观能力和压力对学生学习健美操的成绩具有一定的影响。     

我国七人制橄榄球运动发展现状与对策

七人制橄榄球运动是一项高强度身体对抗球类竞技体育集体运动项目,具有很高的观赏性.该运动在我国起步较晚,目前虽取得一定成绩,但与世界七人制橄榄球强国相比差距较大,整体竞技水平较低,高水平竞技后备人才储备匮乏,是制约我国七人制橄榄球运动发展的主要因素.     

Are the Yo-Yo intermittent recovery test levels 1 and 2 both useful? Reliability,responsiveness and interchangeability in young soccer players

Abstract

The aim of this study was to compare the reliability, internal responsiveness and interchangeability of the Yo-Yo intermittent recovery test level 1 (YY1), level 2 (YY2) and submaximal YY1 (YY1-sub). Twenty-four young soccer players (age 17 ± 1 years; height 177 ± 7 cm; body mass 68 ± 6 kg) completed each test five times within pre- and in-season; distances covered and heart rates (HRs) were measured. Reliability was expressed as typical error of measurement (TEM) and intraclass correlation coefficient (ICC). Internal responsiveness was determined as effect size (ES) and signal-to-noise ratio (ES_TEM). Interchangeability was determined with correlation between training-induced changes. The TEM and ICC for distances in the YY1 and YY2 and for HR in YY1-sub were 7.3% and 0.78, 7.1% and 0.93 and 2.2% and 0.78, respectively. The ESs and ES_TEMs were 0.9 and 1.9 for YY1, 0.4 and 1.2 for YY2 and ?0.3 and ?0.3 for YY1-sub. Correlations between YY1 vs. YY2 and YY1-sub were 0.56 to 0.84 and ?0.36 to ?0.81, respectively. Correlations between change scores in YY1 vs. YY2 were 0.29 and ?0.21 vs. YY1-sub. Peak HR was higher in YY1 vs. YY2. The YY1 and YY2 showed similar reliability; however, they were not interchangeable. The YY1 was more responsive to training compared to YY2 and YY1-sub.     

江西省普通高校竞技体育发展的影响因素与对策研究

运用文献资料、问卷调查,专家访谈等研究方法,分析江西省普通高校竞技体育发展过程中存在的主要问题,研究发现,生源数量减幅较大、田径项目出现严重生源危机、生源竞技水平不高、教练员缺乏经验、物质保障不足等都是目前江西省普通高校竞技体育面临的严峻问题.针对以上问题,提出了合理布局项目,非均衡协调发展、“一条龙”体系领先,多渠道并举、优化教练员队伍、拓宽渠道,形成多元经费结构等相关的建议,期望为江西省高校竞技体育的发展提供较为科学的理论参考.     

北京秋季大气挥发性有机物及相关污染物特征分析

综合分析北京地区典型秋季挥发性有机物（VOCs）及各相关污染物的污染水平以及日夜变化趋势,说明VOCs的组成和浓度特征.VOCs平均小时浓度为54.6ppb,其中,非甲烷碳氢化合物（NMHCs）为38.0ppb;含氧挥发性有机物（OVOCs）为10.4ppb.通过对VOCs特征组分的日夜变化和特征比值（E/E和B/T）的分析,发现研究区域大气老化现象明显,且受机动车尾气影响显著.结合后向气流轨迹分析和对采样期间正午时段的B/T值特征的解释,印证了以上结论.

蔡元培大学教育理念对大学学术管理的启示

蔡元培的大学教育理念可概述为：大学是“研究高深学问”的机关，“研究高深学问”是大学理想的价值取向；大学是“囊括大典，网罗众家”之学府，民主、自由是大学理想的氛围；大学以“养成硕学闳材，应国家需要为宗旨”，培养“健全之人格”的大学生。蔡元培大学理念给当前大学的学术管理以启示：学术管理是大学内部管理的核心；在学术管理活动中必须建立以学术权力为主导的权力运行机制；必须确立教师在大学学术管理中的主体地位。     

The multi-stage fitness test as a predictor of endurance fitness in wheelchair athletes

Abstract

The aims of this study were two-fold: (1) to consider the criterion-related validity of the multi-stage fitness test (MSFT) by comparing the predicted maximal oxygen uptake ([Vdot]O_2max) and distance travelled with peak oxygen uptake ([Vdot]O_2peak) measured using a wheelchair ergometer (n = 24); and (2) to assess the reliability of the MSFT in a sub-sample of wheelchair athletes (n = 10) measured on two occasions. Twenty-four trained male wheelchair basketball players (mean age 29 years, s = 6) took part in the study. All participants performed a continuous incremental wheelchair ergometer test to volitional exhaustion to determine [Vdot]O_2peak, and the MSFT on an indoor wooden basketball court. Mean ergometer [Vdot]O_2peak was 2.66 litres · min^?1 (s = 0.49) and peak heart rate was 188 beats · min^?1 (s = 10). The group mean MSFT distance travelled was 2056 m (s = 272) and mean peak heart rate was 186 beats · min^?1 (s = 11). Low to moderate correlations (ρ = 0.39 to 0.58; 95% confidence interval [CI]: ?0.02 to 0.69 and 0.23 to 0.80) were found between distance travelled in the MSFT and different expressions of wheelchair ergometer [Vdot]O_2peak. There was a mean bias of ?1.9 beats · min^?1 (95% CI: ?5.9 to 2.0) and standard error of measurement of 6.6 beats · min^?1 (95% CI: 5.4 to 8.8) between the ergometer and MSFT peak heart rates. A similar comparison of ergometer and predicted MSFT [Vdot]O_2peak values revealed a large mean systematic bias of 15.3 ml · kg^?1 · min^?1 (95% CI: 13.2 to 17.4) and standard error of measurement of 3.5 ml · kg^?1 · min^?1 (95% CI: 2.8 to 4.6). Small standard errors of measurement for MSFT distance travelled (86 m; 95% CI: 59 to 157) and MSFT peak heart rate (2.4 beats · min^?1; 95% CI: 1.7 to 4.5) suggest that these variables can be measured reliably. The results suggest that the multi-stage fitness test provides reliable data with this population, but does not fully reflect the aerobic capacity of wheelchair athletes directly.
