Data are presented as the mean ± standard error. P value: ANCOVA test result. Data are adjusted for sex, age, height, weight, and presence of diabetes mellitus. TE: Tae-Eum, SE: So-Eum, SY: So-Yang, VT: tidal volume, VC: vital capacity, IC: inspiratory capacity, ERV: expiratory reserve volume, IRV: inspiratory reserve volume, FVC: forced vital capacity, FEV1: forced expiratory volume in 1 sec, VO2max: maximal oxygen consumption, and AT: anaerobic threshold.
