Background and Purpose: The aims and purpose of the study is to determine the effect of knee isotonic and isokinetic exercises on blood pressure in normal males. Method: It is a quasi-experimental study with single group which received both isokinetic and isotonic exercises. Conclusion: 60 normal young males were taken in the study and were given isokinetic well as isotonic exercises and their effect on blood pressure was noted. The study shows marked increase in systolic and diastolic pressure with both exercises but the changes were more in isokinetic exercise than in isotonic exercise.
