Background: Inspiratory muscle execises is a pulmonary rehabilitation methods in patients with chronic obstructive pulmonary disease (COPD) that relatively new and highly developed Research on muscle exercises is very varied and not yet adjustable. This study investigated the differences effects of exercises and workload exercises on maximal inspiratory pressure (MIP), shortness of breath symptoms, exercise capacity, and quality of life among stable COPD patients.
Methods: The experiments was conducted by quasi experimental, pretest and posttest design. The study was conducted in RSUD Dr Moewardi Surakarta from September to November 2015. Chronic obstructive pulmonary disease patients (n=34) with inspiratory muscle weakness (MIP <60 cmH2O) meeting the inclusion and exclusion criteria were recruited in the study by purposive sampling and subsequently devided in two groups exercises with threshold load training dan resistive load training during 6 weeks.
Results: A total of 30 subjects can complete the exercise well and 4 subjects did not resume the study because of various causes. The study showed that inspired threshold and resistive training training exercises could increase the MIP, decrease the Borg scale, increase the range of a 6 minute walking test, and decrease the CAT score. This study did not show any significant differences in the results of the inspired muscle training of the threshold load training method with resistive load training in terms of MIP changes, the Borg caustic scale score, the 6 minute walking distance, and the CAT score.
Conclusion: Both methods of exercises are effectively used as a single lung rehabilitation method in stable COPD patients although both methods have differences ways of working. (J Respir Indo. 2017; 37: 188-94)
