Eccentric Training in Individuals With COPD

"* Aerobic exercise training on a downhill walking treadmill with the following settings: 10% negative incline and constant speed corresponding to 75% of the average speed recorded during the initial 6-Minute walk test.~* Resistance training: 5 minutes of warm-up on the manual ergometer, then 3 sets for 10 repetitions of the leg extension (performed unilaterally in eccentric phase) with a load of 75% of 1 repetition maximum (concentric) for the first two weeks. The following two weeks, 3 sets for 10 repetitions will be performed on the leg press (performed unilaterally in the eccentric phase) with 75% load of 1 repetition maximum (concentric). In addition, patients will perform 3 upper extremity strengthening exercises (free weights or elastic bands), including 2 sets of 10 repetitions for each exercise."

"* Aerobic exercise training using the cycle ergometer at an intensity calculated as follows: 2 minutes with load equal to 20% of maximum load, then 25 minutes with initial load at 50% of maximum load calculated as 103.217 + (30.500xGender) + (-1.613xAge) + \[0.002x6-Minute walk work (6MWW)\]. \[Sex: female = 0; male:1\] \[6MWW = 6-Minute walk distance x weight in kg\].~* Resistance training: 5 minutes of warm-up on the manual ergometer, then 5 exercises for upper and lower limbs performed with free weights or elastic bands. For the first 2 weeks will be performed 2 sets X 20 repetitions with 1 minute break between sets and a load that allows to perform no more than 20 repetitions. For the following 2 weeks, 3 sets of 10 repetitions x 10 repetitions with 2 min break between sets and a load that allows for no more than 10 repetitions."
