Brief summary: The purpose of the present study was to evaluate the effect of a beach tennis session on 24-hour ambulatory blood pressure in adults with hypertension. The main hypothesis is that a single session of beach tennis would decrease ambulatory blood pressure compared with a non-exercise control session.

Detailed description: In this randomized crossover trial, participants performed randomly assigned two experimental sessions: a beach tennis session and a non-exercise control session. The beach tennis session started with a standardized 5-minute warm-up consisting of basic techniques, followed by three 12-minute beach tennis matches with 2-minute intervals between them. Heart rate and rating of perceived exertion were continuously recorded during the beach tennis session, and enjoyment was measured after the beach tennis session. The control session was performed in seated rest. Both experimental sessions lasted 45 minutes. Ambulatory blood pressure was measured continuously for 24-hour after sessions.

Eligibility criteria: Inclusion Criteria:

* Office blood pressure between 130-179 and 80-110 mmHg for systolic and diastolic blood pressure, respectively;
* Non-engaged in structured exercise programs in the last 3 months before the beginning of this study;
* Able to perform the proposed exercises.

Exclusion Criteria:

* Underlying cardiovascular disease in the last 24 months such as acute myocardial infarction, angina, stroke or heart failure;
* Diseases that reduce life expectancy;
* Smokers;
* BMI \>39.9 kg/m²;
* Diabetic proliferative retinopathy.
