1、我國優(yōu)秀田徑運動員競技能力臨場發(fā)揮穩(wěn)定性摘要：對第11屆全運會田徑?jīng)Q賽「8名運動員競技能力的發(fā)揮水平進行了統(tǒng)計分析。結果表明：參加本屆比賽運動員競技能力總體表現(xiàn)出較高的穩(wěn)定性，發(fā)揮水平達101.09%,男女運動員的發(fā)揮基本在同一水平上，共有70.83%的運動員正?；虺０l(fā)揮,29.17%的運動員失常發(fā)揮。男女前3名競技能力的發(fā)揮水平明顯優(yōu)于4~8名，即名次愈好其競技能力發(fā)揮水平愈高。不同亞類項群及其分組項目運動員競技能力的發(fā)揮水平具有鮮明的項群特征，發(fā)揮水平依大小排序為：耐力性〉綜合性＞速度性〉快速力量性；中長距離〉超常距離〉全
2、能〉短跨〉跳躍〉投擲。耐力性項群競技能力的發(fā)揮最為穩(wěn)定，快速力量性項群發(fā)揮的穩(wěn)定性最差。不同年齡運動員發(fā)揮水平存在著顯著差異，而處于最佳競技發(fā)展穩(wěn)定階段(24?30歲)的運動員臨場發(fā)揮具有較高的穩(wěn)定性。關鍵詞：訓練與競賽；競技能力；臨場發(fā)揮；競技能力發(fā)揮;穩(wěn)定性；田徑運動員中圖分類號：G82文獻標識碼：A文章編號:1006-7116(2010)06-0076-04StabilityofgameperformanceofcompetitivecapacitiesofexcellenttrackandfieldathletesinC
