With the COVID-19 pandemic, the physical activity (PA) levels of university students declined as a result of confinement. The aim of the study was to analyse the segmentation of university students according to physical self-concept ratings and to determine the differences between each cluster during the pandemic. The sample consisted of 492 students aged 18-31 years, 36.8% male and 63.2% female, who were administered the PSDQ-S and IPAQ instruments. The data collected were analysed with SPSS software, from which descriptive statistics, a cluster analysis from the PSDQ-S, was obtained. The IPAQ and socio-demographic variables were used to characterise the groups. Finally, a non-hierarchical K-means analysis was performed to establish the clusters. The results reported three different group profiles of students. Significant differences were found in all self-concept variables analysed, with the exception of some items. In relation to PA level, it could be established that the Positive Physical Self-Concept group had the highest PA level and was composed of 52.1% females and 34.4% males, showing a high physical self-concept, whereas, in the Medium-Physical Self-Concept and Negative-Physical Self-Concept groups, females were predominant in number. They were also the least physically active groups and had a low physical self-concept.
随着 COVID-19 大流行，由于禁闭，大学生的身体活动 (PA) 水平下降。本研究的目的是根据身体自我概念评分对大学生进行细分，并确定大流行期间每个群体之间的差异。该样本由 492 名年龄在 18-31 岁的学生组成，其中 36.8%为男性，63.2%为女性，他们接受了 PSDQ-S 和 IPAQ 测试。使用 SPSS 软件对收集的数据进行分析，从 PSDQ-S 中获得了聚类分析。使用 IPAQ 和社会人口统计学变量来描述这些群体。最后，进行了非层次 K-均值分析以确定聚类。结果报告了学生的三种不同群体特征。除了一些项目外，所有分析的自我概念变量都存在显著差异。关于 PA 水平，可以确定积极的身体自我概念组具有最高的 PA 水平，其中 52.1%为女性，34.4%为男性，具有较高的身体自我概念，而在中等身体自我概念和消极身体自我概念组中，女性居多。他们也是最不活跃的群体，身体自我概念较低。
