Participant characteristics.

Data are presented as mean ± standard deviation. BMI: Body Mass Index; PAI: Physical Activity Index (maximum score = 15); FVC: Forced Vital Capacity; FEV1: Forced Expiratory Volume in 1 second; FRC: Functional Residual Capacity; PImax: maximal inspiratory pressure; PEmax: maximal expiratory pressure; % pred: percentage predicted; N/A: not applicable; Significant p-values (p<0.05) in bold.

数据以平均值±标准差形式呈现。体重指数（Body Mass Index，BMI）；身体活动指数（Physical Activity Index，PAI，最高得分=15）；用力肺活量（Forced Vital Capacity，FVC）；一秒用力呼气容积（Forced Expiratory Volume in 1 second，FEV1）；功能残气量（Functional Residual Capacity，FRC）；最大吸气压力（maximal inspiratory pressure，PImax）；最大呼气压力（maximal expiratory pressure，PEmax）；预测百分比（percentage predicted，% pred）；不适用（not applicable，N/A）；p值具有统计学显著性（p<0.05）时以粗体标注。
