化学类论文中溶液组成的规范表达

采用GB3102.8-1993中规定的量名称和量符号是规范溶液组成表达的依据和基础.该标准中列出的相关量名称和量符号可划分为"浓度"类、"分数"类和"比"类.进一步分析指出:对由SI基本量"物质的量"导出的导出量,必须遵守使用单位"摩尔"应指明物质的基本单元的使用规则;组合单位中词头的选用应符合有关词头的使用规则;量纲一的量的量值表达则需遵守相关规则.据此,就目前化学类论文中有关溶液组成的几个常见问题进行简析.

Body composition differences by age and playing standard in male rugby union and rugby league: A systematic review and meta-analysis

ABSTRACT

This systematic review and meta-analysis aimed to determine differences in body compositionn between playing standard and age in male rugby union and rugby league athletes. The MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines for design, implementation, and reporting were followed. Studies were required to be in male rugby union or league and have body composition as the primary or secondary outcome. Data was required to be presented separately for positional groups and body composition presented as whole-body. A systematic search was performed in PubMed, Cochrane Library, MEDLINE, SPORTDiscus, and CINHAHL via EBSCOhost. 57 studies were included for meta-analysis. Results highlighted significantly higher fat-free mass in senior elite than senior sub-elite or junior elite athletes for all RU and RL forwards. Small and non-significant differences were found in fat mass between rugby union playing standards and age categories. Rugby league senior elite forwards had less fat mass than junior elite forwards. Practitioners should prioritise training and nutritional strategies that maximise fat-free mass development, especially in junior elite cohorts.

体育院校冰上运动对男大学生身体成分和骨密度的影响

为探讨冰上运动项目对男大学生身体成分和骨密度的影响,采用韩国ZEUS9.9身体成分分析仪和法国Osteospace MEDI LINK超声骨量测量仪,分别对体育院校2010～2012级冰上运动专项的男大学生和没有运动专项的男大学生进行身体成分和骨密度的测量,并对实验数据进行统计学的分析与比较。结果显示,冰上运动专项男大学生左右腿肌肉含量、基础代谢率显著高于对照组（P＜0.05）,骨密度显著低于对照组大学生（P＜0.05）,这可能与调查对象的生活方式、饮食习惯、训练年限、运动水平以及冰上运动项目的教学内容有关。建议冰上运动专项男大学生改变不良生活方式、均衡饮食,适当调整运动训练方案,加强下肢的力量训练,提高运动成绩。     

Multiple components of fitness improved among overweight and obese adolescents following a community-based lifestyle intervention

Fitness is an important component of health, and obese adolescents regularly have poor fitness. Unfortunately, few have assessed the impact of community-based lifestyle interventions on multiple components of fitness. The purpose of this study was to assess the impact of participation in a community-based intervention involving adolescents and parents on multiple components of fitness of obese adolescents. In a within-subject, waitlist controlled clinical trial with 12 months follow-up in Western Australia, participants (n = 56) completed multiple fitness measures at baseline, immediately prior to beginning an 8-week intervention and at 3, 6 and 12 months during a maintenance period. Performance on the shuttle walk was improved immediately post-intervention (increase of 42.8 m, 95% CI: 7.5, 78.2) and at 12 months post-intervention (increase of 44.6 m, 95% CI: 1.3, 87.8) compared with pre-intervention. Muscle performance of quadriceps and deltoids were improved post-intervention (increase of 1.1 (95% CI: 0.1, 2.1) kg · F and 1.0 (0.02, 2.1) kg · F, respectively) and all muscle performance measures were improved at 12 months following the intervention. There were no changes in waist circumference. A community-based lifestyle programme such as Curtin University’s Activity, Food and Attitudes Program (CAFAP) may be a viable strategy for improving fitness in overweight adolescents.
