Chronic obstructive pulmonary disease (COPD) is a progressively
debilitating disease, which, over time, may compromise patient ability to perform
activities of daily living (ADL). The purpose of this study was to examine the
relationships between selected parameters of physical fitness and performance of
ADL in COPD patients. METHODS: A convenience sample of 23 COPD patients (11 men
and 12 women, age 6869 years) was studied at the conclusion of an exercise
rehabilitation program. Patients were assessed using the Continuous Scale
Physical Functional Performance 10 Test (PFP-10) battery, chest press, leg press,
and a symptom limited graded exercise test. RESULTS: The PFP-10 global score was
54 +/- 12, and 11 patients fell below a global score of 57, which has been
established as the threshold for independence. Peak oxygen uptake (VO(2peak)) was
20 +/- 4 mL.kg(-1).min(-1), the forced expiratory volume in 1 second/forced
expiratory volume ratio was 0.58 +/- 0.12, grip strength was 61 +/- 16 kg (both
hands), and chest press and leg press were 4 +/- 3 and 12 +/- 7 kg/kg body
weight, respectively. The associations between the PFP-10 VO(2peak) and leg press
were modest (r = 0.501, P = .014; and r = 0.547, P = .008) as was grip strength
(r = 0.418, P = .047). There was no association between the PFP-10 and forced
expiratory volume, forced expiratory volume in 1 second/forced vital capacity, or
chest press (r = -20.040, P = .856; r = 20.212, P = .330; and r = 0.120, P =
.595), respectively. CONCLUSION: The results of this investigation suggest that
lower body strength is important in optimizing ADL performance in COPD patients.
