The Effect of Threshold Loading Training and an Innovative Respiratory Training Devices with Lower Torso Sports Training in Asthma Patients: A Randomized Trial.

This study investigated the influence of two different devices with lower torso sports training in patients with asthma. Patients with asthma ( = 300) aged 55-60 years with FEV1/FVC ratio < 65%, who were repeatedly admitted to a pulmonary rehabilitation centre, participated. Patients were evaluated and randomized into two groups (experimental group 1; EXP-1, = 150, who applied a conventional threshold loading device, and experimental group 2; EXP-2, = 150, who used an innovative respiratory training device).
