Acute Effects of Swimming on the Arterial Pressure of Hypertensive Adults

Aim. The purpose of this work was to verify the acute effects of a regular swimming programme on the arterial pressure of hypertensive adults.

Material and methods. The sample was composed of 26 individuals who presented mild to moderate hypertension. The subjects were divided into two groups: the Experimental Group (EG) comprising 13 subjects (four men and nine women) and the Control Group (CG) comprising 13 subjects (seven men and six women), with average ages of 38.40 ± 8.24 and 38.36 ± 8.96 years, respectively. GE individuals took part in a regular swimming programme consisting of three weekly fifty-minute sessions of training (ST) for 10 weeks, whereas GC individuals were instructed not to alter their physical activity and nutritional habits. The Kruskal-Wallis test was used to determine statistical significance (p < 0.05).

Results. At the end of the ten weeks, an increase of 4.8% in Systolic Blood Pressure at rest (from 133.67 ±2.26 to 138.56 ± 3.23) and an increase of 7.8% in Diastolic Blood Pressure (from 83.15 ± 1.50 to 89.67 ± 7.19) were observed.

Conclusion. The results allow us to conclude that a regular swimming programme, consisting of training sessions three times a week for 10 weeks, was not sufficient to significantly alter the acute pressure levels of hypertensive adults.
