In this clinical trial, chronic obstructive pulmonary disease (COPD) patients will receive either three months of inspiratory or expiratory muscle training according to the pattern of resting/exertional breathing timing. In parallel with the training, nutrition treatment with medium-chain triglycerides (MCT) will also be given. The purpose of the present study was to determine the effect of training and treatment on the changes in balance between inspiratory and expiratory muscle strength and, subsequently, on the pattern of exertional breathing timing. We will also evaluate the benefits of these changes in exertional breathing timing, if any, on exercise tolerance in COPD patients.

Exertional changes in breathing timing (Ti/Ttot)
1.Symptom (CAT score, SGRQ score)
2.Body weight, Body Mass Index
3.Respiratory function (FEV1, %FEV1, FEV1%, VC, and %VC)
4.Forced oscillation technique (resistance and reactance)
5.The following parameters in cardiopulmonary exercise testing (CPET): minute ventilation (VE), oxygen uptake (VO2), carbon dioxide output (VCO2), breathing frequency (fR), tidal volume (VT), physiologic dead space/tidal volume ratio (VD/VT), dyspnea intensity (Borg scale), and exercise time
6.Respiratory muscle pressure (MIP), maximum inspiratory pressure (MIP), minimum expiratory pressure (MEP), |MIP|/MEP
7.Dual-energy X-ray absorptiometry (DEXA)

Treatment
Food | Other |
1)All patients will be classified into two groups according to the change in Ti/Ttot during CPET. The patients in the Ti/Ttot increased group will receive inspiratory muscle training; the patients will receive inspiratory muscle training 30 times, twice per day for 3 months. The load of the respiratory training will be started at 20% of the maximum inspiratory pressure obtained at baseline and can be increased once every 2 weeks to up to 50% of the maximum pressure.
2)Administration of edible oil that comprises medium-chain C8 (octanoic acid) and C10 (decanoic acid) triglycerides.
<The administration schedule of edible oil>
2.5 g of edible oil that comprises medium-chain C8 and C10 triglycerides will be administered orally, once daily, for 3 months.
