Since resistance band training is reportedly to reduce HbA1c and increase insulin sensitivity [27], and since strength exercise combined with or without aerobic exercise reduce risk for T2DM [28], provide anti-inflammatory effect [29], and exhibited better respiratory function [30], we postulated that Taichi concurrently combined with resistance band training would likely afford additional beneficial effect on lung diffusion function in patients with T2DM. Here, INS is linked to type 2 diabetes mellitus.
