Beach Tennis And Hypertension Study (BAH)

January 12, 2021 updated by: Hospital de Clinicas de Porto Alegre

Effects of a Beach Tennis Training Session on Ambulatory Blood Pressure in Hypertensive Individuals: a Randomized Clinical Trial

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control session
Control session without any exercise. The participants remained in seated rest throughout 45 min.
Experimental: Beach Tennis session
The participants performed a beach tennis training session throughout 45 min.The session started with a standardized 5-minute warm-up consisting of basic techniques (i.e., serve, volley, forehand, and backhand) followed by three 12-minute beach tennis matches with 2-minute intervals between the games. We used regular beach tennis rules in the game, which was played on a regular beach tennis court (i.e., 16 m long by 8 m wide and net 1.70 m high).
Behavioral: Beach Tennis session
The Beach Tennis training session will be composed by a warm up of 5 min of BT in which technical exercises (i.e., serve, volley, forehand and backhand) will be performed After that, 3 BT small games of 12 min with a 2 minute interval between games using the conventional rules of sport will be performed. Before the session and after each small game, data regarding heart rate, blood pressure and rate perceived exertion will be recorded.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ambulatory Blood Pressure
Time Frame: 24 hours after control and beach tennis sessions
Day-time, night-time and 24h ambulatory blood pressure measured through automatic oscillometric device after 45 min of control session and beach tennis session
24 hours after control and beach tennis sessions

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Systolic blood pressure
Time Frame: 45 minutes
Systolic blood pressure in mmHg will be measured using automatic oscillometric before and after each experimental session throughout 45 min.
45 minutes
Diastolic blood pressure
Time Frame: 45 minutes
Diastolic blood pressure in mmHg will be measured using automatic oscillometric before and after each experimental session throughout 45 min.
45 minutes
Blood Pressure Variability
Time Frame: 24 hours
Systolic and diastolic BP values obtained in the 24-hour ambulatory blood pressure monitoring, with valid measures included in a programmed software to calculate the average real variability of these measures.
24 hours
Enjoyment (PACES questionnaire)
Time Frame: 5 minutes
Enjoyment will be measured after beach tennis session, the scale is composed of 18 items in a bipolar affirmations format (i.e., "amused" versus "not-amused") punctuated in a range from the minimum value "1" to the maximum value "7".
