Effects of Dynamic Exercise and Dynamic Resistance Training in Rehabilitation of Patients after Surgical Coronary Revascularization

Abstract

Summary Cardiac rehabilitation is an integral part of the complex therapy of cardiac patients. The aim of this study was to determine the effect of dynamic exercise and dynamic resistance training on exertion tolerance, muscle strength of the upper and lower extremities, and respiratory index in patients after surgical coronary revascularization. The study included 84 patients divided into two groups. Both groups of respondents were included in the complex cardiac rehabilitation program of the interval type. In the first group, the patients performed dynamic exercise. The second group of patients received a combination of dynamic exercise and dynamic resistance training. At the end of the rehabilitation treatment, which lasted 21 days, a statistically significant difference in muscle strength of the upper and lower limbs was observed in both groups (p < 0.05); statistically significant difference was found in relation to exertion tolerance in both groups (p < 0.001); a statistically significant difference in duration of exercise stress test was observed in the both groups (p < 0.05); respiratory index values showed statistically significant differences in both groups (p < 0.001). After the rehabilitation treatment, in both groups of patients there were statistically significant differences in increasing the muscle strength of the upper and lower extremities, exertion tolerance, and respiratory index; however, beneficial effects of physical training were more pronounced in the group of subjects included in the program of resistance exercise for the upper and lower extremities.
