摘要
通过文献资料法、数理统计法、录像观察法,以2019赛季巴西美洲杯巴西、秘鲁、阿根廷、智利、哥伦比亚、乌拉圭、委内瑞拉、巴拉圭等8强球队技术统计指标为研究对象,利用RSR对2019赛季巴西美洲杯8强球队攻防综合技术能力进行评价。结论:巴西队的进攻技术能力最突出,RSR值高达0.96.在防守技术能力方面,乌拉圭RSR值为0.83,且以巴西和乌拉圭的攻防综合技术能力最强,均属于A级水平。2019赛季巴西美洲杯8强球队攻防RSR值与最终排名的相关系数r=0.571,(P<0.05),两者呈显著相关。建议:巴拉圭队在今后的训练中提高进攻技术能力,委内瑞拉队、秘鲁队和哥伦比亚对在今后训练中对于进攻技术能力和防守技术能力都应该进一步提高。
