Study aim: To compare the effects of 6-week isokinetic and isotonic training programmes on heart rate and blood pressure in high school students.Material and methods: Twenty-nine healthy, untrained male student subjects aged 15 - 18 years participated in the study.

Heart rates (HR) and blood pressure were determined before and after the training period, both pre- and post-exercise.Results: Mean resting HR and exercise-induced HR-increase significantly decreased post-training in IT group (by 19 and 24%, respectively; p<0.001). The exercise-induced HR-increase significantly increased post-training in IK group (by 17%; p<0.001). Significant (p<0.01) training-induced decreases in the systolic pressure (SBP) were found in both training groups (IT and IK, by 7 and 6%, respectively).Conclusions: The results may be of practical importance for athletes and health professionals who administer openchain resistance exercises.
