低海拔及中度高原训练对男子柔道运动员运动能力的影响

为了探讨低、中度高原训练对运动能力的影响，本系统观察15名广东省男子柔道运动员在中度高原(1891m)和低海拔(1000m)进行2—3周训练前后Hb、CK、BUN、血清睾酮(T)、皮质醇(C)和T／C比值的变化并进行比较。研究发现：(1)高原训练中，Hb先降低后显升高，CK活性则是显升高，然后逐渐恢复，BUN开始变化不明显，随后显下降，回到平原后再升高至恢复；血清T、T／C比值显升高，而C显下降，保持高睾酮低皮质醉水平；(2)低海拔训练对运动员的血液生化指标、激素及运动能力有一定的影响，但不如中度高原训练效果明显；(3)中度高原—平原—低海拔交叉训练能使运动员适应过程加快，提高机能水平。

The turning point in 1985. The history of appraisal and disposal of records in Iceland

The article sets off with a brief summary of the history of appraisal and disposal of records as processed at the National Archives of Iceland (NAI) since its establishment in 1882 to present times. Rules on appraisal and disposal of records introduced in 1900, 1911, and 1916 were ignored and all records were kept. Status quo remained until 1985 when a new National Archives Act was passed. The appraisal and disposal process adopted then is described and explained. It included the publication of instructions on records management as well as forms relating to records management. The influence of acts of law on the appraisal and disposal process is explained. Finally the experience with the arrangement of organised appraisal in Iceland is described.
