Abstract
Objective
To compare treadmill versus cycling-based exercise in cardiac rehabilitation (CR)
on functional capacity (FC) outcomes.
Data Source
Databases were searched for randomized studies using single modality continuous exercise.
Study Selection
Studies implemented a continuous cycling or treadmill protocol for patients with either
coronary artery disease (CAD) or chronic heart failure (CHF). The effect of single
modality exercise on FC (VO2peak) was analyzed. Differences in the effect of CR on FC was assessed between the
mode subgroup (cycling vs treadmill) and disease state subgroup (CAD vs CHF) within
both the cycling and treadmill groups.
Data Extraction
Data were extracted from 23 studies including 600 patients (mean age 60y, 86% men).
Data Synthesis
There was a significant difference in effect size between studies that used cycling,
Hedges’ g=0.85 (95% confidence interval [95% CI], 0.52-1.17; k=13) and studies that
used treadmill exercise, Hedges’ g=0.46 (95% CI, 0.22-0.70; k=8). Within cycling studies
(n=14), FC was higher among CAD patients, Hedges’ g=1.03 (95% CI, 0.65-1.42; k=9)
compared to those with CHF, Hedges’ g=0.40 (95% CI, 0.09-0.71; k=4, P<.001). Conversely, among treadmill studies (n=9), FC was higher among CHF patients,
Hedges’ g=0.94 (95% CI, 0.23-1.65; k=2) compared to CAD, Hedges’ g=0.33 (95% CI, 0.19-0.47;
k=5; P<.01).
Conclusions
According to identified studies, when cycling was the primary mode of exercise in
CR, there was larger change in FC compared to treadmill exercise. In addition, CAD
patients experienced greater gains in FC when cycling was the primary mode of exercise
in CR, while CHF patients benefited more from treadmill-based exercise programs.
