The purpose of this study was to examine the impact of the Coronavirus disease 2019 on male and female anthropometric variables and physical performance.
This study utilized a mixed (time [PRE vs POST], gender [male vs female]) methods design to examine changes in the body mass index and physical fitness performance measures prior to and following closures. Data were collected from 264 third through eighth graders. This sample consisted of 131 males and 133 females. The data was collected through anthropometric (body mass index) and physical performance measures and was analyzed with separate 2 × 2 mixed-factorial analyses of variance (time [PRE, POST] × gender [male, female]).
The findings indicated both males and females exhibited mean increases in the body mass index (+10.6%; 18.8-20.8 kg·m-2, P < .001, partial η2 = .627) and decreases in push-ups (-35.6%; 7.3-4.7 repetitions, P < .001, partial η2 = .371), sit-ups (-19.4%; 22.7-18.3 repetitions, P < .001, partial η2 = .420), and the Progressive Aerobic Cardiovascular Endurance Run test (-26.7%; 31.4-22.4 laps, P < .001, partial η2 = .644) scores from PRE to POST.
The results of this study demonstrate that both males and females exhibited significant anthropometric and physical performance losses during the Coronavirus disease 2019 shutdown.
本研究旨在探讨 2019 年冠状病毒病对男性和女性人体测量变量和身体表现的影响。
本研究采用混合（时间[前测与后测]、性别[男性与女性]）方法设计，以检验在关闭前后身体质量指数和身体体能表现测量值的变化。数据来自 264 名三至八年级学生。该样本由 131 名男性和 133 名女性组成。数据通过人体测量（身体质量指数）和身体表现测量收集，并使用单独的 2×2 混合因素方差分析（时间[前测、后测]×性别[男性、女性]）进行分析。
研究结果表明，男性和女性的身体质量指数均呈现出平均增长（+10.6%；18.8-20.8kg·m-2，P<.001，部分η2=0.627），俯卧撑（-35.6%；7.3-4.7 次，P<.001，部分η2=0.371）、仰卧起坐（-19.4%；22.7-18.3 次，P<.001，部分η2=0.420）和渐进式有氧心血管耐力跑测试（-26.7%；31.4-22.4 圈，P<.001，部分η2=0.644）的得分均从前测到后测下降。
本研究结果表明，在 2019 年冠状病毒病关闭期间，男性和女性均表现出显著的人体测量和身体表现下降。
