[Lack of influence of body mass on blood pressure reduction after exercising].
BACKGROUND Hypertension ( H ) is associated with a large number of co-morbidities , including obesity . The correlation between two variables has been investigated . OBJECTIVE To analyze the correlation between the loss of body mass and blood pressure reduction in hypertensive patients undergoing exercising programs ( EP ) .  METHODS One hundred eleven hypertensive patients with overweight or obesity were r and omly divided into an experimental group ( EG ) . Out of these , 57 ( 58 + /- 8.9 years old ) participated in a three-month EP conducted three times a week in aerobic exercise sessions from 50 % to 70 % of VO2 peak for 30 to 60 minutes and resistance exercises ; and a control group ( CG ) with 54 ( 60 + /- 7.7 years old ) who did not participate in the EP . In the EG , blood pressure ( BP ) was measured before each session and the measurement of anthropometric variables ( AV ) at the beginning of the program and after three months . In the CG the BP and the VA were evaluated in the doctor 's office at the beginning and at the end of the study . Data were expressed as mean + /- st and ard deviation ( SD ) . Pearson correlation and t test were used . A value of p < 0.05 was considered significant . RESULTS In the CG there was no significant difference in AV and BP at the beginning and at the end of the study . In the EG , there was no significant alteration in the AV , however , there was blood pressure reduction of 12 % in systolic BP ( -17.5 mmHg , p = 0.001 ) and 9 % in Diastolic BP ( -8.1 mmHg , p = 0 . 01 ) at the end of the study . There was no correlation between the AV and decrease in BP ( r = 0.1 ) . CONCLUSION The blood pressure reduction was not correlated with reduction of anthropometric measures after the exercising period
