RESULTS
On entry, subjects were well matched by age
(average age was 67 years in all three groups).
According to the WIQ 3 persons were 1/2-block
clandicators, 5 were one-block claudicators, 12 were
two-block claudicators, 6 were three-block claudicators,
and 3 were five-block claudicators. None of the
patients could walk further than five blocks. Patients
randomized to strength training reported fewer years
ofclaudication (2 + 1) than did patients in the other
two groups (4 + 2 for treadmill-trained group and
4 + 3 for control group) but were similar with
respect to the frequency of cardiovascular comorbidity,
smoking history, and medication use as previously
reported. 2~ Patients did not change their
medication use or smoking status during the course
of the study.
