Compared to the control group, there was a significant
increase in the physical component summary score (SF-
36 data) immediately following training (6.7, 0.2–13.0,
p = 0.04; table 2 ). At the 3-month follow-up, the improvement
in the physical component summary score was
maintained compared to baseline, but the difference between
the exercise and control group was no longer significant
( table 2 ). Anxiety decreased in the exercise group
following training and remained below baseline at the
3-month follow-up (both p ! 0.05), however the difference
between groups did not reach statistical significance
( table 2 ).
6MWD improved in the exercise group immediately
following training (p ! 0.01; table 3 ) and remained above
baseline at the 3-month follow-up (p ! 0.01). Despite being
no change in 6MWD in the control group at either
time point, the magnitude of change in 6MWD between
the exercise and control groups did not reach statistical
significance ( table 3 ).
