Instructor Interpersonal Behaviours in Classical Pilates as a Pathway to Improve Blood Pressure Control and Well-being in Hypertensive Adults

5 oktober 2026 bijgewerkt door: Vera Alexandra da Graça Bártolo, Instituto Politécnico de Leiria

The aim of this study is to investigate, during a Classical Pilates programme with participants suffering from high blood pressure, whether supportive communication from the instructor to the participant has any effect on the impact of the practice on physiological (blood pressure) and psychological (retention, motivation, quality of life and life satisfaction) variables, compared with neutral and routine communication.

Gedetailleerde beschrijving

Background: Pilates appears to have a positive impact on the management and control of blood pressure. However, studies in this field are still inconsistent, combining classical and contemporary techniques as well as equipment, and the protocols are not always clear. Furthermore, there are no studies that highlight the importance of the instructor's communication and the impact this may have on both blood pressure outcomes and psychological outcomes. This protocol aims to explore the influence, on the above-mentioned outcomes, of supportive communication based on Self-Determination Theory, used during classical Pilates classes.

Methods and Design: The study consists of a 24-week, two-arm randomised controlled trial in which adults with hypertension will practise a Classical Pilates sequence in either a control group receiving neutral feedback or an experimental group receiving supportive feedback based on Self-Determination Theory. The 50-minute sessions will take place twice a week. Outcomes will be assessed at three time points: baseline, 12 weeks and 24 weeks, and will consist of measurements of resting blood pressure, adherence, basic psychological needs, motivational regulation, quality of life and life satisfaction.

Discussion: The study will provide an understanding of the influence of supportive communication on physiological and psychological variables, and may contribute to the development of safe, low-cost intervention programmes that ensure adherence and effectiveness in clinical populations.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Ander: Control: Classical Pilates

A group of people with high blood pressure following a predefined Classical Pilates protocol, with neutral communication from the instructors (a regular class that takes into account safety, corrections and adaptations to the exercises, but without any specific support).

The control group will undergo the same 24-week intervention as the experimental group, with two 50-minute sessions per week, following the same classical Pilates matwork protocol described above. There is no supportive communication in this variant, instead, communication is neutral, as usual in any class. Neutral communication refers to natural communication that includes tips, technical adjustments, answers to queries and safety advice, but without any specific concerns regarding autonomy, competence or relatedness.

Experimenteel: Experimental: Classical Pilates and Need Supportive Communication

A group of people with high blood pressure following a predefined Classical Pilates protocol, with communication designed to support their basic psychological needs, based on Self-Determination Theory.

The intervention will last 24 weeks, and both groups (intervention and control) will follow a classical Pilates matwork programme, twice a week in 50-minute sessions. Lessons for the control and experimental groups will be conducted separately. The programme will consist of 50-minute sessions of classical Pilates matwork sequence, based on the original exercises by Joseph Pilates. In this experimental group, in addition to exercise, supportive communication (autonomy, competence and relatedness) will be introduced.

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Blood Pressure
Tijdsspanne: 3 times: Baseline, 12 weeks and 24 weeks

Resting SBP and diastolic blood pressure (DBP) measured with a validated automatic sphygmomanometer following 2024 ESC guidelines (three measurements, 1-2 min interval; the mean of the last two readings will be used for analysis).

Ambulatory blood pressure monitoring will not be included due to logistical and financial constraints in a small-scale study. Furthermore, as this method is uncomfortable, it may itself constitute a barrier to the study, given that three measurements must be taken within a short period of time (3 months). However, automated office blood pressure measurement, taken at rest, when carried out rigorously and in accordance with the guidelines, may offer a level of accuracy similar to that of ambulatory monitoring.

3 times: Baseline, 12 weeks and 24 weeks

Tijdsspanne
Adherence/Retention
Tijdsspanne: 3 times: baseline, 12 weeks and 24 weeks

Attendance records (percent of sessions attended) and study completion rate.

3 times: baseline, 12 weeks and 24 weeks
Motivational Regulation: Behavioural Regulation in Exercise Questionnaire-3 (BREQ-3)
Tijdsspanne: 3 times: baseline, 12 weeks and 24 weeks

The Portuguese version of the BREQ-3 assesses the regulation of motivation in exercise through 18 items, which are subdivided into six dimensions (amotivation, external regulation, introjected regulation, identified regulation, integrated regulation and intrinsic motivation), with responses given on a 5-point Likert scale, ranging from 0 ("I strongly disagree") to 4 ("I strongly agree").

3 times: baseline, 12 weeks and 24 weeks
Short Form Health Survey-12v2 (SF-12v2)
Tijdsspanne: 3 times: baseline, 12 weeks and 24 weeks

The SF12v2 is a shortened version of the SF-36 (Short-Form Health Survey-36), which measures physical and mental health in relation to quality of life on a 12-item scale covering eight dimensions (physical functioning, physical role limitations, bodily pain, general health perceptions, energy/vitality, social functioning, emotional role limitations and mental health), which are summarised into two domains: the physical component summary and the mental component summary. Items are scored on a scale of 0 to 100 ("worst health state" to "best health state").

3 times: baseline, 12 weeks and 24 weeks
Satisfaction With Life Scale (SWLS)
Tijdsspanne: 3 times: baseline, 12 weeks and 24 weeks

The SWLS is a subjective, self-reported well-being scale that assesses overall life satisfaction, including five short items rated on a 7-point Likert scale ranging from 1 ("strongly disagree") to 7 ("strongly agree").

3 times: baseline, 12 weeks and 24 weeks
