%X there are scarce studies evaluating the modification of ventilatory response to upper limb exercise (ule) post-training in copd patients. a prospective, randomized, controlled study was performed comparing two groups: training lower limbs (ll), vs. ll plus upper limb training (ul), in relation to their pre and post-training ventilatory response to ule. a total of 43 copd patients were included; 84% male, 6 (14%) gold moderate stage (ii), 15 (35%) severe stage (iii), and 22 (51%) very severe (iv); 28 patients completed the study. after ule, in ul group (n = 14) a training increased isotime vt (p < 0.0001) was observed, as well as an increase in the inspiratory capacity isotime percentage (ic, 8.8%, p = 0.001), in the ti isotime (29.3%, p = 0.022) and in the ti/tot isotime (37.4%, p = 0.0004). also, te isotime was reduced (26%, p = 0.009) and ic isotime was increased (p = 0.01) after ule. in ll group (n = 14), training increased vt/ti isotime (66.86%, p = 0.0005) after ule. also, after ule a decrease in ti isotime (27.9%, p = 0.015) and in ti/tot isotime (22.74%, p = 0.00016) were observed. a moderate correlation was observed between ¦Ä respiratory rate and ¦Äic after ule, only for post-training in ul group (r = -0.53 , p < 0.001). comparing both groups in relation to their responses to ule, only in the ul group was a reduction observed in te isotime (p = 0.049) and vt/ti (p = 0.0015), higher ti isotime (p = 0.0019), ti/tot isotime (p = 0.000076) and ic isotime (% predictive, p = 0.01). ul training modified ventilatory response to ule and it also reduced air trapping in copd patients.
