Muscle resistance training is often combined with aerobic endurance
training during rehabilitation of patients with coronary artery disease. However,
the clinical effects of additional lower-extremity low-intensity muscle
resistance training during early rehabilitation (within the first month after
coronary revascularization) in patients with coronary artery disease remain
unclear. Design: Prospective randomized controlled trial. Subjects: Sixty
patients with coronary artery disease. Methods: Subjects were randomly assigned
to early aerobic endurance training (n = 30) or combined aerobic endurance and
resistance muscle training (n = 30). Subjects performed 18 (standard deviation 2)
exercise sessions (at 65% VO2peak, for 40 mins/session).
In resistance muscle
training, additional low-intensity (12-20 repetition maximum) resistance muscle
exercises were performed.
The following parameters were evaluated: exercise
capacity, body composition, blood lipid profile, glycaemic control, blood
endothelial progenitor cell and cytokine content, and muscle performance.
Results: A total of 47 patients with coronary artery disease completed the
intervention. Total body lean tissue mass tended to increase with greater
magnitude (p = 0.07), and blood high-density lipid cholesterol content increased
with significantly greater magnitude in resistance muscle training (p < 0.05),
compared with aerobic endurance training. Maximal exercise capacity, ventilatory
threshold, and muscle performance increased, and steady-state exercise
respiratory exchange ratio, and adipose tissue mass reduced significantly (p <
0.05), without differences between groups (p < 0.05). Conclusion: In early
aerobic endurance training intervention in patients with coronary artery disease,
additional low-intensity resistance muscle training contributes to a greater
increase in blood high-density lipid cholesterol content, and tends to affect lean tissue mass.
