OBJECTIVE: To investigate the effects of elastic tubing training compared with
conventional resistance training on the improvement of functional exercise
capacity, muscle strength, fat-free mass, and systemic inflammation in patients
with chronic obstructive pulmonary disease.
DESIGN: A prospective, randomized,
eight-week clinical trial. SETTING: The study was conducted in a
university-based, outpatient, physical therapy clinic. SUBJECTS: A total of 49
patients with moderate chronic obstructive pulmonary disease. INTERVENTIONS:
Participants were randomly assigned to perform elastic tubing training or
conventional resistance training three times per week for eight weeks. MAIN
MEASURES: The primary outcome measure was functional exercise capacity. The
secondary outcome measures were peripheral muscle strength, health-related
quality of life assessed by the Chronic Respiratory Disease Questionnaire (CRDQ),
fat-free mass, and cytokine profile. RESULTS: After eight weeks, the mean
distance covered during six minutes increased by 73 meters (+/-69) in the elastic
tubing group and by 42 meters (+/-59) in the conventional group (p < 0.05). The
muscle strength and quality of life improved in both groups (P < 0.05), with no
significant differences between the groups. There was a trend toward an improved
fat-free mass in both groups (P = 0.05). After the first and last sessions, there
was an increase in interleukin 1beta (IL-1beta) and interleukin 10 (IL-10) in
both groups, while tumour necrosis factor alpha (TNF-alpha) was stimulated only
in the conventional training group. CONCLUSION: Elastic tubing training had a
greater effect on functional exercise capacity than conventional resistance
training. Both interventions were equally effective in improving muscle strength
and quality of life.
