Variables are shown as mean SD or mean (95% CI).

p: difference between before and after exercise program

*p value adjusted for gender.

*Glucose conversion factor to SI 0.05551; $Conversion factor to SI 7.175.

HOMA-IR: homeostatic model assessment-insulin resistance index

HR: Heart rate (beats per minute)

SBP: systolic blood pressure

DBP: diastolic blood pressure

VO2max: maximal oxygen intake

SDNN: standard deviation of all the normal R_R intervals

LF/HF: low-frequency/high-frequency index

FVC: forced vital capacity

FEV1: forced expiratory volume at 1 second

FEV1/FVC: forced expiratory volume at 1 second/forced vital capacity

PEF: peak expiratory flow.
