University of the Basque Country research aimed at finding out effects of intensity of physical exercise in controlling high blood pressure

Anyone complaining of high blood pressure at a doctor’s consultancy will leave with a lot of instructions aimed at guiding the patient to lead a healthier lifestyle. 20% of the adult Basque population suffers from high blood pressure, a figure which rises to 60% amongst the over 65s.

Amongst others, measures inevitably recommended by the doctor are combatting stress, reducing or eliminating the consumption of tobacco and alcohol, taking care with eating habits and controlling weight and, above all, practising some physical exercise regularly. Nevertheless, on many occasions this must-do list is so general and all-embracing that it impedes the good intentions of having an actual physical exercise programme that is optimum.

In order to carry out the study the research team required the participation of volunteers with high blood pressure. The research will aim to determine the different progress profiles of these patients, being subject to individualised programmes of physical exercise of different intensities. To this end, and in a random manner, participating individuals will be divided into three study groups: a non-supervised control with general healthy lifestyle recommendations; a second supervised group with an on-going physical exercise programme and of moderate intensity; and a third, supervised physical exercise programme of different intensities, alternating intense and moderate modes.

Those participating in the study will undergo preliminary physical stress trials at the physiology laboratory at the UPV-EHU’s Faculty of Physical Activity and Sports Sciences. Then, over the of twelve-week period of the research project, the participants from the supervised exercise group will exercise mainly with a treadmill or on a bicycle in programmed intensities of exercise and individually, depending on the results of prior physical stress trials. On terminating the twelve-week period, the physical stress trials undertaken at the beginning will be repeated and a comparison of the two sets of results made of blood pressure parameters and of other physiological and anthropometric variables.

Evaluation trials

All those participating in the supervised groups will attend the centre where the physical exercise programmes take place for a total of 24 sessions (twice a week for the twelve weeks), supervised by students of Physical Activity and Sports Sciences.

The main trials to be undertaken are the following:

1. Ambulant Blood Pressure Monitoring (AMBP) for 24 hours at both the start and the end of the programme, required for confirming High Blood Pressure diagnosis (HBP).

2.Physical stress trials on an ergometric bicycle and treadmill with measurement of variables in rest mode, submaximum mode and peak mode in order to evaluate the cardiorespiratory functional capacity and blood pressure.

3. Walking trial to evaluate functional capacity and blood pressure.
