To determine a safe threshold resistive load that induce minimal respiratory muscle damage in clinical measures like maximal inspiratory pressure, delayed onset muscle soreness and plasma creatine kinase following a bout of inspiratory loading exercise in COPD patients.
30 patients with GOLD stages II and III were selected with random sampling and were divided into Group A, B & C and received inspiratory threshold loading (ITL) at intensities of 70, 50 and 30% maximal inspiratory pressure (MIP) respectively for 30 minutes. Pre and post ITL readings of delayed onset muscle soreness at 0, 4, 24 and 48 hours and maximal inspiratory pressure and plasma creatine kinase at 0, 24 and 48 hours were conducted.
There was a significant difference in VAS and Body chart diagram of delayed onset muscle soreness, MIP and plasma creatine in Group A than C (p < 0.05), with no marked difference between Group A and B (p > 0.05).
Inspiratory threshold loading performed at low intensity loads (≤30 % normal MIP) was considered as a safe threshold resistive load that induce minimal respiratory muscle damage in COPD patients.
