The influence of home isolation during COVID-19 on the physical fitness development of college students: a study utilizing repeated measures analysis of variance.

Abstract

BACKGROUND:

Research on the impact of COVID-19-induced home isolation on the physical fitness of college students is limited. This study aims to compare and analyze the physical fitness test scores of college students in two groups: those who experienced home isolation and those who did not, over three consecutive years after enrolment, to investigate the effects of home isolation on the physical fitness development of Chinese college students.

METHODS:

This comparative study included two longitudinal surveys conducted among medical college students. The participants were divided into an experimental group and a control group. The physical fitness indicators measured included body mass index (BMI), vital capacity (VC), 50-metre run, sit-and-reach, standing long jump, 1000/800-metre runs (males/females), pull-ups (males) and sit-ups (females). Repeated measures analysis of variance (ANOVA) was employed, and the Greenhouse-Geisser correction was applied when Mauchly's assumption of sphericity was violated. Pairwise comparisons were conducted using the Bonferroni method.

RESULTS:

A total of 6580 students participated in the study, with 3360 students (1490 males, 1870 females) enrolled in 2019 as the experimental group and 3220 students (1326 males, 1894 females) enrolled in 2017 as the control group. All participants completed the physical fitness tests for three consecutive years. The results showed that the experimental group exhibited decreased performance in the 1000-metre and 800-metre runs, and improved performance in the sit-and-reach test. After the end of home isolation, there was an improvement in the performance of the 1000-metre run and 800-metre run, while no significant differences were observed in the trends of the other tested indicators.

CONCLUSION:

The findings of this study indicate that the home isolation environment during COVID-19 had a significant impact on the physical fitness of college students, specifically in terms of endurance and flexibility qualities, as well as male BMI. To better prepare for future public health emergencies and mitigate the effects of isolation, teaching students endurance exercises that can be performed at home should be prioritized. Furthermore, physical education programs should be improved to enhance student flexibility.
