A history of bronchiolitis may lead to changes in health-related physical fitness in children and adolescents. The aim of this study was to analyze the influence of history of bronchiolitis on health-related physical fitness components (muscle strength and cardiorespiratory fitness) in children and adolescents. A cross-sectional study was conducted, and 86 participants (aged 7-14 years; all males) were divided into two groups: a group with (n = 40) and without (n = 46) history of bronchiolitis. Muscle strength was assessed with handgrip and isometric quadriceps strength tests with handheld dynamometers and the five-times sit-to-stand test. Cardiorespiratory fitness was assessed with the six-minute walk test (6MWT). The Mann-Whitney test was used to compare the health-related physical fitness tests between groups and the binary logistic regression model was used to estimate the potential risk or protective factors in participants. No significant differences were observed between the groups in muscle strength tests. Participants without bronchiolitis walked a greater distance in the 6MWT than those with bronchiolitis ( = 0.002), and this appears to reproduce a protective factor in the group without bronchiolitis with an odds ratio of 0.99 [95% confidence interval: 0.98-0.99]. In this study, a history of bronchiolitis appears to influence cardiorespiratory fitness, but not muscle strength, in children and adolescents.
细支气管炎病史可能会导致儿童和青少年与健康相关的身体素质发生变化。本研究的目的是分析细支气管炎病史对儿童和青少年与健康相关的身体素质组成部分（肌肉力量和心肺适能）的影响。开展了一项横断面研究，86名参与者（年龄7至14岁；均为男性）被分为两组：有细支气管炎病史组（n = 40）和无细支气管炎病史组（n = 46）。使用握力计和手持测力计进行等长股四头肌力量测试以及五次坐立试验来评估肌肉力量。通过六分钟步行试验（6MWT）评估心肺适能。采用曼-惠特尼检验比较两组之间与健康相关的身体素质测试结果，并使用二元逻辑回归模型估计参与者的潜在风险或保护因素。在肌肉力量测试中，两组之间未观察到显著差异。无细支气管炎病史的参与者在6MWT中的步行距离比有细支气管炎病史的参与者更远（P = 0.002），这似乎在无细支气管炎病史组中产生了一个保护因素，优势比为0.99 [95%置信区间：0.98 - 0.99]。在本研究中，细支气管炎病史似乎会影响儿童和青少年的心肺适能，但不会影响肌肉力量。
