: To examine the effect of prior concussion history on cognitive test performance and concussion symptom reporting among adolescent youth rugby league athletes.: Participants were male elite level youth rugby league players (N = 73; Mean Age = 15.8; SD = 0.9; range = 14-18 years).: CogSport performance based on participants group; those who reported no previous concussions (n = 30),1-2 previous concussions (n = 19), and ≥3 previous concussions (n = 29).: 73 participants with valid CogSport scores were included in the cognitive analyses. All participants were included in the symptom analyses. There were no differences between the groups with 0,1-2, or ≥3 previous concussions for processing speed, attention, learning, or working memory. There was atrend for those with multiple prior concussions to report more baseline preseason symptoms.: There were no differences in scores on the CogSport test among those with ahistory of 0,1-2, or ≥3 prior concussions. Consistent with prior studies, youth with ahistory of multiple past concussions are more likely to endorse baseline preseason symptoms.
: 研究既往脑震荡史对青少年英式橄榄球联赛运动员认知测试表现和脑震荡症状报告的影响。: 参与者为男性精英水平的青年英式橄榄球联赛运动员（N = 73；平均年龄 = 15.8；标准差 = 0.9；范围为 14-18 岁）。: 根据参与者的分组评估 CogSport 表现；无既往脑震荡者（n = 30）、1-2 次既往脑震荡者（n = 19）和≥3 次既往脑震荡者（n = 29）。: 73 名具有有效 CogSport 评分的参与者被纳入认知分析。所有参与者均被纳入症状分析。在处理速度、注意力、学习和工作记忆方面，无既往脑震荡、1-2 次既往脑震荡和≥3 次既往脑震荡的组之间无差异。有既往多次脑震荡的参与者报告更多基线赛季前症状的趋势。: 在既往 0 次、1-2 次或≥3 次脑震荡史的参与者中，CogSport 测试得分无差异。与既往研究一致，有既往多次脑震荡史的青少年更有可能报告基线赛季前症状。
