Abstract: 
The effect of exercise on the progression of hypertension and development of heart failure has been extensively studied in spontaneously hypertensive rats (SHRs), but results published thus far have not revealed a clear picture. Studies differ with respect to the age and sex of rats, duration of exercise and exercise protocols. This study was aimed to examine the influence of age at the start of exercise and the effect of the duration of exercise on blood pressure and hypertrophy, which has not been previously investigated. We identified 18 reports in the literature (with a total of about 410 rats) that investigated the effect of exercise on SHR. A reduction in blood pressure was observed in rats that started exercise protocols in the pre-hypertensive or very early hypertensive state, but not in older rats. Exercise lowered the heart weight-to-body weight ratio in rats starting exercise at a very early age, but not in rats at an advanced age. A reduction in blood pressure was observed in animals that had a short period of training, but the effect was lost when the duration of exercise was prolonged. Exercise reduced resting heart rates in all groups and increased the heart weight-to-body weight ratio in groups that were exposed to free running wheels, but not in rats that performed treadmill exercise. In conclusion, exercise per se does not reduce blood pressure in SHR with established hypertension and may increase the incidence of myocardial hypertrophy, depending on the form of exercise.
