国家治理现代化视域下我国体育智库的责任与担当     

杨涛 《河北体育学院学报》2020,34(6):50-55

党的十九届四中全会明确提出了“坚持和完善中国特色社会主义制度、推进国家治理体系和治理能力现代化的重大意义和总体要求”。在新的历史时期，我国体育智库的新使命在于推进体育强国、健康中国和体育治理现代化建设。基于此，采用文献资料法和逻辑分析法，从外部和内部两个角度，对我国体育智库的责任和担当进行深入探讨。认为体育智库对内要注重更新管理体制，完善运行机制，建设和优化人才培养体系；对外要通过科研成果转化实现体育产业高质量发展，重塑体育治理生态，提升国家体育文化软实力和国际体育地位硬实力，促进体育融合发展，最终服务于我国体育治理体系和治理能力现代化。  相似文献

Key somatic variables associated with,and differences between the 4 swimming strokes

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).  相似文献

为进一步实现CUBA与CBA联赛新时期改革计划,疏通我国篮球后备人才战略培养路径,以“新时期”CUBA与CBA的人才衔接与培育为研究对象,运用文献资料、录像观察、数理统计等方法,对CBA联赛选秀球员进行综合分析。研究结果表明:1)存在问题包括组织机构衔接不畅、选秀球员竞技水平不精、人才培养观契合度不高及俱乐部注意程度不足4个方面。2)改善路径包括逐渐推进多元主体衔接度及流畅性、全面优化高校球员竞技能力及水平、消除人才培养僵化及保守化、扎实提升俱乐部关注程度及积极性。  相似文献   

Development of a chemically defined medium for Planctopirus limnophila to increase biomass production     

《Electronic Journal of Biotechnology》2021

BackgroundPlanctomycetes is a phylum of biofilm-forming bacteria with numerous biosynthetic gene clusters, offering a promising source of new bioactive secondary metabolites. However, the current generation of chemically defined media achieves only low biomass yields, hindering research on these species. We therefore developed a chemically defined medium for the model organism Planctopirus limnophila to increase biomass production.ResultsWe found that P. limnophila grows best with a 10 mM sodium phosphate buffer. The replacement of complex nitrogen sources with defined amino acid solutions did not inhibit growth. Screening for vitamin requirements revealed that only cyanocobalamin (B12) is needed for growth. We used response surface methodology to optimize the medium, resulting in concentrations of 10 g/L glucose, 34 mL/L Hutner’s basal salts, 23.18 mM KNO₃, 2.318 mM NH₄Cl and 0.02 mg/L cyanocobalamin. The analysis of amino acid consumption allowed us to develop a customized amino acid solution lacking six of the amino acids present in Aminoplasmal 10%. Fed-batch cultivation in a bioreactor using the optimized medium achieved a final ΔOD₆₀₀ of 46.8 ± 0.5 after 108 h, corresponding to a cell dry weight of 13.6 ± 0.7 g/L.ConclusionsThe optimized chemically defined medium allowed us to produce larger amounts of biomass more quickly than reported in earlier studies. Further research should focus on triggering P. limnophila biofilm formation to activate the gene clusters responsible for secondary metabolism.How to cite: Kruppa OC, Gerlach D, Fan R, et al.

Key somatic variables in young backstroke swimmers     

Senda Sammoud  Alan Michael Nevill  Yassine Negra  Raja Bouguezzi  Chaabene Helmi  Younés Hachana 《Journal of sports sciences》2019,37(10):1162-1167

The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification).  相似文献
