To see or not to see : talent identification in the Swedish Football Association
- 2019
-
Ingår i: Journal of Beijing Sport University. - 1007-3612. ; :7, s. 53-64

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this article is to explore whether context and coaching cultures influence coaches’ practical experience and their unarticulated and embodied knowledge, and thus their different ways of seeing and defining talent. Using a cultural sociological perspective, we challenge the commonly held assumption that talent identification is, or can be made into, a rational and objective process. Our interpretations and analyses are based upon interviews with 15 soccer coaches in four districts within the Swedish Football Association’s talent organization program. The results imply that coaches’ talent identification is guided by what feels “right in the heart and stomach”; but what feels right is greatly influenced by their experience of previous identifications, interpretations of what elite soccer entails, and the coaching culture in which they find themselves.

- 长时间剧烈运动能引起循环中的红细胞损伤和老化;而长期运动训练有可能导致运动性贫血的发生,据最近的一些研究表明,尽管一次长时间剧烈运动可引起红细胞被破坏增多,但长期运动训练引起的运动性贫血,在很多情况下属于血液稀释作用造成的。本文设计6周身体训练并在训练的不同阶段进行剧烈运动,测定反映红细咆老化状态的几个敏感指标:2,3—DPG、红细胞肌酸含量及红细胞生成素等,旨在确认不同强度的训练及剧烈运动对红细胞生成和老化的影响,为进一步完善运动性贫血理论提供依据。

Tidskriftsartikel (refereegranskat)abstract
- 以二种不同强度运动,测定运动结束后不同时间内股四头肌MDA含量及SOD、GSH-PX活性,并测定了相应时间内的血清酶活性.结果发现长时间力竭性运动引起肌组织MDA含量增加的同时,SOD和GSH-PX活性下降,血清CK、LDH及Mb含量上升;短时间间歇运动后,尽管MDA变化不明显,但SOD和GSH-PX趋于上升,且血清酶活性也在运动后有上升表现.

Ingår i: Yantai Teachers University Journal. - 1004-4930. ; 9:1, s. 56-59
-
Tidskriftsartikel (refereegranskat)abstract
- The effects of fatigued swimming on lipid peroxidation in erythrocyte membranae and plasma of rat have been studied. The results show that fatigued swimming can increase the MDA level and decrease the activities of Na+ , K+-ATPase and Ca++-ATPase in erythrocyte membranae.

-
Forskningsöversikt (refereegranskat)abstract
- Both an acute sport and long-term exercise can result in changes in blood volume.Studying these changes, finding their changing patterns and knowing their effects on sport ability have been the problems of a lot of reserchers. In this review. previous works of other peoples were reviewed and analysed in order to provide a clue forfurther studies.

Tidskriftsartikel (refereegranskat)abstract
- 本文采用２种不同的运动强度对受试者进行６周的运动训练，并在训练的不同阶段进行剧烈运动，测定了运动前后反映红细胞老化状态的各项指标：膜ＭＤＡ含量、Ｎａ，Ｋ－ＡＴＰａｓｅ活性、ＳＯＤ活性以及红细胞唾液酸含量。结果表明，不同强度的运动训练均引起血液系统中年轻红细胞比例上升，但影响的程度有所差异。不同训练阶段进行剧烈运动，由于血液系统对训练的适应状态不同，其影响也有所不同，但剧烈运动的结果仍引起红细胞老化加速。
