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.
