Objective:
To find the proportion of the adult population that practice physical exercise habitually.
Design:
An observational study of a crossover nature.
Setting:
The counties of Alt Camp and Conca de Barberà (Tarragona).
Patients And Other Participants:
A two-stage random sampling (stratified by age, gender and type of town) was performed on the different municipal registers in the counties and a representative sample of 672 people between 15 and 90 was extracted.
Interventions:
By means of a home interview, a questionnaire to determine whether the interviewees practiced regular physical exercise was filled out (physical activity carried out in their free time, three or more days per week).
Measurements And Main Results:
The most notable finding was that 47.3% of the whole sample practiced physical exercise (49.5% of men and 45.3% of women, NS). The youngest (15 to 29) were those who did most physical exercise (58.7%): this was statistically significant in comparison with the other age groups (p < 0.01).
Conclusions:
The results are comparable to those recorded in other studies in our country and could also serve as an indicator for those population-groups with similar demographic, socio-economic and cultural characteristics to our own.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Longitudinal Studies
Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
