Abstract:
This study aimed to compare the effects of a single bout of beach tennis on post-exercise hypotension in men and women with hypertension. In this crossover trial, adults with hypertension were randomized into two experimental sessions: beach tennis and control sessions. For the beach tennis session, they warmed up with basic techniques for 5-min and played three matches lasting 12-min each, interspersed with 2-min recovery intervals. During the control session, the participants remained seated at rest without any exercise. Each protocol lasted for 45-min. Office blood pressure was assessed before and after the experimental sessions for 1-h. A generalized estimating equation analysis was used to compare the main effects of sex on blood pressure. Statistical significance was set at P < 0.05. Fifty-eight participants (29 men and 29 women aged 35-60) participated in this study. Comparing beach tennis with control, systolic/diastolic blood pressure was lower after exercise in men (-17 mmHg, P < 0.001 / -8 mmHg, P < 0.001) and women (-10 mmHg, P = 0.04 / -4 mmHg, P = 0.016). The reduction in systolic blood pressure was greater in men than in women (-7 mmHg, P = 0.040). In adults with hypertension, a single recreational beach tennis session acutely reduced blood pressure in both sexes, with a more pronounced effect observed in men. Tailored beach tennis protocols may be necessary to elicit optimal benefits for women.Trial registration: This trial was registered in the Registro Brasileiro de Ensaios Clínicos (ReBEC) under identifier number RBR-9nm4zs9, with the first registration on March 01, 2024 ( https://ensaiosclinicos.gov.br/rg/RBR-9nm4zs9 ).

Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
