The purpose of this investigation was to determine the relationship between university club and intramural sports participation and student grades via the American College Health Association National College Health Assessment (NCHA) survey, while controlling for confounding variables. Data were obtained from the NCHA for the fall 2008, spring 2009, fall 2009, and fall 2010 time periods. The original sample included 178,091 respondents. After inclusion and exclusion criteria, the final analytic sample included 85,316 respondents. Multinomial logistic regression was used to evaluate the role of participation in club and/or intramural sports on self-reported grade averages. Analyses were adjusted for significant covariates that have been identified as potentially impacting academic success. In general, sport participants were more likely to report higher grade averages than nonparticipants. The strongest relationships were found for participants of club sports. Future research should investigate relationships between club and intramural sports and other indicators of academic success.

俱乐部和校内运动的参与与大学生的学业成就

这项调查的目的是通过控制美国大学健康协会全国大学健康评估（NCHA）调查来确定大学俱乐部和校内体育参与与学生成绩之间的关系，同时控制混杂变量。从NCHA获得了2008年秋季，2009年春季，2009年秋季和2010年秋季时间段的数据。原始样本包括178,091名受访者。在纳入和排除标准之后，最终的分析样本包括85,316名受访者。多项逻辑回归用于评估自我报告的平均成绩对参加俱乐部和/或壁内运动的作用。对已经确定为可能影响学术成就的重要协变量进行了分析调整。一般来说，体育参与者比非参与者更有可能报告更高的平均成绩。俱乐部运动参与者之间的关系最密切。未来的研究应调查俱乐部与壁内运动之间的关系以及其他学术成就指标。
