Haider et al. excluded persons with insufficient cognitive capacity (MMSE ≤17) and several conditions that might serve as a contraindication to receiving physical training (e.g., chemo- or radiotherapy, insulin-treated diabetes, or chronic obstructive pulmonary disease III or IV) [113–116], while the PP studies lacked specification of their exclusion criteria. Here, INS is linked to chronic obstructive pulmonary disease.
