A research study was conducted to check the presence of obesity in COPD and how it affects exercise performance in patients with dyspnea disorder (Ora et al., 2011). It was hypothesized that the effect occurs due to the volume-reducing impacts, which convey respiratory and mechanical muscle function. Generally, in patients who do not have airway diseases, obesity occurs because of restrictive ventilator deficit resulting from the respiratory system. A sample size of 12 patients with mild obesity of body mass index 34.9 kg/m2 and 12 age-matched with normal-weight s24.9 kg/m2 (Ora et al., 2011).

The participants included men and women aged between 55-85 years with a precise diagnosis of COPD. The forced expiratory volume, which had one, was compared with forced vital capacity. It was noted that there might be traces of other diseases apart from COPD, which causes exercise limitations. The conditions may include metabolic, neuromuscular, cardiovascular, musculoskeletal, and other respiratory diseases. Also, there are crucial indicators that cause clinical exercise testing. Similarly, an observation was made on the patients who experience extreme physical conditions like training, passive, or housebound (O'Donnell et al., 2012). The body mass index is evident in some underweight people, usually less than 18.5 kg/m2 (Ora et al., 2011).


The result revealed that 12 FEV1 –matched average weight, and 12 COPD patients gave different results. The chest CT scan was evaluated, and emphysema was present in all six patients, four mild and two moderate in NW subjects. Of eight patients, three were mild, five were on average out of the ten patients, and six patients had a moderate disorder in controlled hypertension (Laviolette et al., 2010). Therefore, in resting, the respiratory mechanical and pulmonary function where the older with obesity had lower respiratory reserve volume than the ones with average body weight (Laviolette et al., 2010). Thus, the research is an ordinal variable (Ora et al., 2011).
