Talent Transfer Selection Index And Evaluation Standard Establishment For Cross-country Skiers In Hebei Province

Objective:by reference and learn the successful experience of international athletes across the item selection,rapidly increasing competitive sports,establish a cross-country skiing athletes in Hebei Province across the item selection index system and evaluation standard,across the work of scientific selection for cross-country skiing project to provide preliminary theoretical framework and practical basis.Methods:Based on the interviews with experts,this paper obtains the primary indexes of cross-country skiing athletes'cross-item selection in Hebei Province,including four categories:shape,quality,function and coach evaluation.Primary indicators were tested on 288 athletes participating in the 2018 cross-country skiing cross material selection in Hebei Province.Univariate anova was used to compare the differences among athletes of different age groups.Independent sample t test was used to compare the differences between athletes of different levels.Factor analysis was combined with expert argumentation to screen out the typical indicators of each dimension and determine the index weight system.The method of percentile was used to determine the evaluation criteria of material selection,and the index system and corresponding evaluation criteria of cross-item material selection in cross-country skiing in Hebei Province were determined.Results:(1)the weight of the four first-level indicators in the index system,including form,quality,function and coach evaluation,is 10%,30%,30%and 30%respectively.The body fat percentage,iliac width/shoulder width,height and lower limb length B/height of female morphological indexes were respectively 50%,20%,20%and 10%.The Beep test for quality indexes includes the distance completed and the standing long jump of level 10,with the weights of 60%and 40%respectively.The maximum power/weight of functional index and Actual score overall stability index(P-L)were respectively 70%and 30%.In terms of male morphology,the ktor index,lower limb length B/height,and iliac width/shoulder width were weighted by50%,30%and 20%respectively.Beep test maximum speed,standing ten level long jump,weight of 60%,40%respectively;The highest power/weight of functional indexes and Actual score overall stability index(P-L)were respectively 70%and 30%.Coaches evaluated the consistency of willpower quality,interest in cross-country skiing and self-confidence of the male and female groups,with weights of 66%,17%and 17%respectively.Plantar pressure and FMS functional screening were used as auxiliary indicators of function and quality,respectively.(2)the chi-square test results show that there is a significant difference between the grade distribution of the selected athletes of Hebei Province cross-country skiing training team and the unselected athletes(x~2=184.30,P=0.00).Conclusions and Suggestions:(1)this study shows that the optimal age range for the scientific selection of cross-country skiers for the 2022 winter Olympic Games is15-16 years old for women and 15-18 years old for men.(2)preliminary construction of cross-country skiing athletes across the scientific material selection indicators of the individual evaluation criteria table and comprehensive evaluation table.The back substitution test shows that the standard has high validity and reliability.Suggestion:in this study,the athletes'material selection index system includes four aspects:form,quality,function and teaching evaluation.In the future study,the existing cross-item material selection criteria should be improved,including psychological indicators and special ability.
