Are you interested in participating in research?

We are looking for women with PCOS aged 18-45 years to take part in our research study.

The study is investigating whether exercise therapy can improve mental health, physical well-being and brain function in patients with PCOS.

Lifestyle modification, including exercise, is an important part of management of patients with PCOS, but the best way in which this can be achieved is unclear.

High Intensity Interval Training (HIIT), which alternates short bursts of intense exercise with short recovery periods, has recently emerged as a time-efficient way to improve cardiovascular fitness.

Studies have also shown that it may improve mood, fatigue and brain function, but the effects in young women with PCOS are unknown.

We therefore plan to undertake a randomised trial comparing HIIT with moderate intensity exercise therapy and usual care in 45 women with PCOS.

The study will be held at the School of Sport, Cardiff Metropolitan University, and Cardiff University Brain Research Imaging Centre (CUBRIC).

It will involve 14 hours of your time taken over 7 assessment visits, which will assess your cardiovascular, metabolic and brain health.

Participants randomised to exercise therapy will be asked to attend 3 sessions of supervised exercise each week for 12 weeks.

The exercise will be conducted on a stationary bike.

You will be reimbursed for your travel expenses.
