摘要
利用人工神经网络强大的函数映射能力 ,提出了反映链球运动员身体素质与专项成绩相关关系的神经网络模型。该模型克服了多元回归模型和灰色模型的缺点 ,在不需要事先确定模型数学表达形式的条件下 ,更为准确地映射出运动员素质训练水平与专项成绩之间的函数关系。并且运用建立起的神经网络模型 ,绘制了素质训练水平与专项成绩之间的关系曲线。
Using the strong mapping function of artificial neural network,a neural network model for the relationship between specific performance and physical fitness of woman hammer thrower is proposed This model overcomes the shortcomings of the multiple regression model and gray model,and thus it can more accurately reflect the function relation between the physical fitness and specific performance Furthermore using this neural network model,this the relationship curve between specific performance and physical fitness is drawn Then hammer thrower may be trained scientifically by the use of these relationship curves
