Pilates may improve heart and metabolic health in sedentary women, study finds

A four-week Pilates programme may improve heart, metabolic and stress measures in previously sedentary women, a small study suggests.

Pilates is a mind-body form of exercise that has been linked to better fitness, balance, posture, muscular endurance, mental wellbeing and quality of life in different groups.

Built around breathing, concentration, control, precision, centring and flow, Pilates is already used in physiotherapy, rehabilitation and preventive health. The new study looked at whether a structured four-week programme could affect cardiovascular, metabolic, body and stress-related measures in sedentary adult women.

The longitudinal study included 30 sedentary women split into two age groups, 30 to 40 and 50 to 60.

All participants completed a standardised, supervised Pilates programme lasting four weeks, with three sessions a week lasting 50 to 60 minutes.

Researchers measured resting heart rate, systolic and diastolic blood pressure, body mass index, abdominal circumference, fasting blood glucose and serum cortisol at the start and end of the programme.

Systolic and diastolic blood pressure are the top and bottom readings in a blood pressure test. Cortisol is a hormone linked to the body’s stress response.

The four-week Pilates programme was linked to improvements in cardiovascular, metabolic, body and neuroendocrine measures, although not every change reached statistical significance within each age group.

In the younger group, significant reductions were seen in heart rate, blood pressure, body mass index and fasting blood glucose after the intervention.

The reduction in blood pressure after the programme was significantly greater in the older group than in the younger group.

Older participants also showed a greater reduction in glucose and cortisol levels after the intervention than younger participants.

Analysis also found significant links between cardiovascular, metabolic and neuroendocrine changes.

In the younger group, this was particularly seen between heart rate and blood pressure responses.

In the older group, it was particularly seen between changes in body mass index and fasting glucose.

The findings suggest Pilates could be a useful multidimensional exercise approach for cardiometabolic health and stress regulation in previously sedentary women.

The researchers said the larger reduction in blood pressure seen in the older group may reflect a higher cardiometabolic burden at the start, leaving more room for improvement after the programme.

The greater reduction in fasting glucose and cortisol in older participants may similarly suggest that people with higher baseline metabolic and neuroendocrine dysfunction could benefit more from structured exercise such as Pilates.

Although Pilates is known to improve body composition through energy use, neuromuscular activation and support for healthier habits, the researchers said the fall in body mass index over four weeks is unlikely to be explained by Pilates alone.

They noted that participants were also told to avoid alcohol, sugar-containing products and sugar-sweetened drinks during the intervention, which may have contributed to the change.

In the younger group, the link between heart rate and blood pressure suggested coordinated cardiovascular responses after Pilates.

The researchers also found that cortisol appeared to be linked to blood pressure and body mass index, suggesting stress-related changes may be tied to cardiovascular and body regulation after the intervention.

In the older group, the link between body mass index and fasting glucose highlighted the relationship between body fat and metabolic regulation.

A positive link between blood pressure and body mass index in this group also suggested that improvements in vascular regulation may be associated with reductions in body mass.

Overall, the findings suggest Pilates-related physiological changes may involve interconnected cardiovascular, body, metabolic and neuroendocrine mechanisms, with different response patterns by age.

The study has important limits. It did not include a non-exercise control group, so it cannot prove Pilates directly caused the changes.

The sample size was also small, which limits how far the findings can be applied more widely.

The authors also noted that cortisol was measured using a single fasting morning sample, which limits conclusions about broader hypothalamic-pituitary-adrenal axis regulation, the system involved in the body’s stress response.

They said larger studies with longer follow-up will be needed to confirm whether Pilates causes these physiological changes over time.
