Abstract :
BACKGROUND: Physical activity (PA) has been associated with reduced blood pressure in
observational epidemiologic studies and individual clinical trials. Since PA is considered as a key
component for the prevention and treatment of hypertension in children and adolescents, the
purpose of this study was to assess blood pressure changes in athletic and non-athletic students
before, during and after PA.
METHODS: The subjects in this experimental study consisted of 60 female athletic (n = 30) and
non-athletic students (n = 30) with an average age of 21-23 years. The athletes were physical
education students and non-athletes were medical students. Blood pressure (BP) at the right
arm was measured in sitting position at 5 minutes before, 6 minutes after starting PA and 5
minutes after the end of the exercise. Weight, height, body mass index (BMI), mean arterial
pressure (MAP) and pulse pressure (PP) were measured by ordinary methods. Data was
analyzed using studentʹs t- test. Results were expressed as mean ± SD. The statistical difference
was considered significant at P < 0.05.
RESULTS: The results showed that while systolic BP (SBP) increased during and 5 minutes
after the end of physical exercise in both groups, diastolic BP (DBP) decreased. However, SBP
values were significantly lower in non-athletic female students compared to the athletes. On the
other hand, DBP values were significantly lower in athletic female students compared to nonathletes.
Moreover, heart rate values were significantly lower at rest, during and 5 minutes after
the end of physical exercise in athlete female students compared to non-athletes.
CONCLUSION: Our results revealed that physical activity reduced arterial BP levels in female
athlete students.
