Isometric strengthening has been rarely studied in patients with
coronary heart disease (CHD), mainly because of possible potential side effects
and lack of appropriate and reliable devices. OBJECTIVE:
We aimed to compare 2
different modes of resistance training, an isometric mode with the Huber Motion
Lab (HML) and traditional strength training (TST), in CHD patients undergoing a
cardiac rehabilitation program. DESIGN: We randomly assigned 50 patients to HML
or TST. Patients underwent complete blinded evaluation before and after the
rehabilitation program, including testing for cardiopulmonary exercise, maximal
isometric voluntary contraction, endothelial function and body composition.
RESULTS: After 4 weeks of training (16 sessions), the groups did not differ in
body composition, anthropometric characteristics, or endothelial function. With
HML, peak power output (P=0.035), maximal heart rate (P<0.01) and gain of force
measured in the chest press position (P<0.02) were greater after versus before
training. CONCLUSION: Both protocols appeared to be well tolerated, safe and
feasible for these CHD patients. A training protocol involving 6s phases of
isometric contractions with 10s of passive recovery on an HML device could be
safely implemented in rehabilitation programs for patients with CHD and improve
functional outcomes.
