Effectiveness of Physical Activity Prescription Among Hypertensive Patients of Primary Health Care.

Effectiveness of Physical Activity Prescription Among Hypertensive Patients of Primary Health Care.

The purpose of this study is to evaluate the effectiveness of a program to increase the physical activity of hypertensive patients using medical services and sports facilities of the Mexican Social Security Institute. The primary hypothesis to be proven is: The intervention will increase the proportion of hypertensive patients complying the physical activity minimum at week to get benefits on health in 20%, compare to patients in control group.

Secondary Hypothesis:

The intervention achieved a significant change in the group of hypertensive patients in the following variables:

1. Decreased levels of systolic and diastolic blood pressure, biochemical markers such as total cholesterol, triglycerides and fasting blood glucose and increased HDL cholesterol.
2. Increase muscular endurance and cardio-respiratory capacity according to the categories of risk stratification.
3. Decreased body weight, body mass index and waist circumference.

Inclusion Criteria:

• diagnosed with high blood pressure <5 years of evolution and / or without use of drug therapy to treat that condition;
• with low levels of physical activity (PA) or physically inactive (less than 150 minutes of PA at week, intensity moderate to vigorous);
• with availability to PA practice or considering begin to PA practice within the next six months (contemplation or preparation stages of the Transtheoretical Model).
• Without cardiovascular risk (assessed previously);
• Without physical or mobility problems that impede PA practice;
• Willingness to participate in the study, fulfill with outlined activities to develop the proposal.

Exclusion Criteria:

• high-risk patients according to the risk stratification of the American College of Sports Medicine;
• fulfill the high recommendation of physical activity (more than 300 minutes per week of moderate to vigorous intensity);
