The purpose of this study was to evaluate the effects of the COVID-19 lockdown on physical fitness among college women living in China and to explore how fitness changed with different physical conditions.
We performed repeated measures of BMI, 800 m running and sit-up performance assessment on college women from one university in China pre and post the COVID-19 lockdown. A total of 3658 (age 19.15 ± 1.08 yr.) college women who completed the same assessment pre and post the COVID-19 lockdown were included in the analysis. We analyzed the data using one way ANOVA and paired-samples -test.
Due to the COVID-19 lockdown, the result shows a significant increase in BMI by 2.91% (95% CI =0.33, 0.40) and a significant decline in 800 m running and sit-up by 7.97% (95% CI =0.69, 0.77) and 4.91% (95% CI = -0.27, -0.19), respectively. College women in the highest quartile level of physical condition (Quartile 4) had more decreases than college women in the lowest quartile level (Quartile 1). Their BMI level was increased by 3.69% and 0.98% in college women in Quartile 4 and Quartile 1, respectively. Their performance of 800 m running was decreased by 9.32% and 7.37% in college women in Quartile 4 and Quartile 1, respectively. Their performance of sit-up was decreased by 13.88% in college women in Quartile 4 while it increased by 10.91% in college women in Quartile 1, respectively.
The COVID-19 lockdown might increase the BMI level and decrease 800 m running and sit-up performance among college women living in China. The decrease for college women in higher quartile level of physical condition (Quartile 4) were more seriously while college women in lower quartile level of physical condition (Quartile 1) were modest.
本研究旨在评估新冠疫情封锁对中国女大学生身体素质的影响，并探讨不同身体状况下身体素质的变化情况。
我们对一所中国大学的女大学生进行了重复的 BMI、800 米跑和仰卧起坐表现评估，在新冠疫情封锁前后进行了评估。共有 3658 名（年龄 19.15±1.08 岁）完成了新冠疫情封锁前后相同评估的女大学生被纳入分析。我们使用单向方差分析和配对样本 t 检验分析数据。
由于新冠疫情封锁，结果显示 BMI 显著增加了 2.91%（95%置信区间=0.33，0.40），800 米跑和仰卧起坐分别显著下降了 7.97%（95%置信区间=0.69，0.77）和 4.91%（95%置信区间=−0.27，−0.19）。身体状况最高四分位（四分位 4）的女大学生比身体状况最低四分位（四分位 1）的女大学生下降幅度更大。四分位 4 的女大学生 BMI 水平增加了 3.69%，四分位 1 的女大学生 BMI 水平增加了 0.98%。四分位 4 的女大学生 800 米跑成绩下降了 9.32%，四分位 1 的女大学生 800 米跑成绩下降了 7.37%。四分位 4 的女大学生仰卧起坐成绩下降了 13.88%，四分位 1 的女大学生仰卧起坐成绩增加了 10.91%。
新冠疫情封锁可能会增加中国女大学生的 BMI 水平，并降低 800 米跑和仰卧起坐成绩。身体状况较高四分位（四分位 4）的女大学生下降幅度更为严重，而身体状况较低四分位（四分位 1）的女大学生则略有下降。
