Abstract

OBJECTIVE
To evaluate the effects of power walking (PW) training on a treadmill in patients with coronary heart disease (CHD) and to compare the cardiovascular effects of PW with usual walking (UW). METHOD: Patients were recruited as participants in phase 2 cardiac rehabilitation program after receiving percutaneous coronary intervention (PCI) due to acute coronary syndrome from our hospital. The participants were divided into the PW group (n=16) and UW group (n=18). All participants received graded exercise test (GXT) and significant difference in maximal oxygen consumption (VO2Max) was not observed between the groups. Aerobic exercise training on treadmill was given for 50 minutes per session, three times a week, for six weeks. Physiological and hematological parameters were tested before and 6 weeks after the cardiac rehabilitation program. Exercise duration, VO2Max, heart rate, blood pressure, and rate pressure product were evaluated through graded exercise test. Hematological measurements included serum lipid profile, and high-sensitivity C reactive protein (hs-CRP).
RESULTS
There were no significant differences in resting heart rate, maximal heart rate, resting systolic and diastolic blood pressures, lipid profile, hs-CRP, VO2Max, and RPP between the PW group and UW group. However, after 6 weeks of the intervention, VO2Max in the PW group (36.03+/-5.69 ml/kg/min) was significantly higher than that in the UW group (29.73+/-5.63 ml/kg/min) (p<0.05).
CONCLUSION
After six weeks of phase 2 cardiac rehabilitation program, the PW group showed significant improvement in VO2Max than the UW group. Thus, it will beneficial to recommend power walking in cardiac rehabilitation program.

  Fig. 1 The power walking group (A) was instructed to swing both arms back and forth while the elbow joint was bent at 90 degrees. The usual walking group (B) was instructed to intermittently grasp on the handles for safety during walking.
