The results of cardiovascular responses of five calisthenics in inpatient cardiac rehabilitation program are reported. Thirty-one patients with acute myocardial infarction (27 males, 4 females, mean age ; 52.5 years old) who were referred to our program from July 1983 to September 1985 were enrolled in this study.
The calisthenics used in our program were trunk rotation (I), trunk lateral bending (II), shoulder flexion and horizontal abduction (III), knee lift (IV), and one step foreward and backward (V) (→see figure 1 on this article). These calisthenics were determined in consideration of those four points ; low intensity (<2-3 Mets), inclusion of total articular movements, easiness, and nearly equal cardivascular stress among each. Two speeds were determined for each calisthenics in order to start from low intensity (slow speed) to higher intensity (fast speed) in a same exercise pattern. In trunk lateral bending, as increasement of speed did not increase its intensity in previous study, trunk flexion and rotation was substituted as fast speed (II'). And slow speed of calisthenics IV, two―count rest was taken between each knee lift in order to make its intensity equal to the other calisthenics. In clinical, each five calisthenics were carried out for two minutes and one to two minutes rests were taken among each.
The mean days on which calisthenics had done were 26.5 day after the onset in slow speed calisthenics and 32.1 day in fast speed. As a results, average values of heart rate, systolic blood pressure, and double product (×10
-2) of each calisthenics showed roughly 80 bpm, 100 mmHg, and 80 in slow speed and 85 bpm, 105 mmHg, and 90 in fast speed, respectively. Ischemic changes of EKGs were not seen, while significant arrythmias were observed in four cases in each speed.
In conclusion, five calisthenics listed here (figure 1) have roughly equal cardivascular stress and are safe as used in cardiac inpatient exercise program.
