 Studies comparing intermittent and continuous treadmill running, and prescribing the same relative work load of 60% of each patient's maximal oxygen uptake (%VO2max) were conducted on nine pa-tients with coronary heart disease. During the stud-ies, comparisons were made of changing rates in %VO2max, systolic blood pressure, heart rate and pressure rate product.

 %VO2max in both intermittent and continuous running periods was steady throughout the studies, and no significant difference was evident between them. Changing rates in systolic blood pressure, heart rate and pressure rate product gradually increased during the runnig periods in both types of runnings, however, each of these rates decreased temporarily after each interval of intermittent running. Changing rates in heart rate between the two types of runnings were not significantly differ-ent. In contrast, however, changing rates in systol-ic blood pressure and pressure rate product at the end of intermittent running periods were significant-ly lower than at the end of continuous running periods. Although there was no significant difference in relative work load between the two types of runnings, the maximum ischemic ST changes during intermittent running were less than during contin-uous running. Additionally, the elapsed time of ischemic ST changes in intermittent running was longer than that in continuous running.

 In conclusion, results of the study indicate that intermittent treadmill running is more useful than continuous treadmill running for cardiac rehabilita-tion in coronary heart disease patients.
