Research interests

My research work focuses on the physiological responses of exercise testing and training in both clinical and sporting paediatric groups. I work on establishing the physiological responses to the imposition of exercise stress in order to apply better prescription of exercise during testing and training of young people. In particular, I am interested in the determining factors of exercise tolerance (fatigue) and how these factors vary according to growth, maturation and sex.

1. Cardiopulmonary and oxidative exercise responses of young cystic fibrosis patients

In the last eight years I have been using my expertise to translate research findings to clinical practice by working with young people who have cystic fibrosis.

2. Helping Little Hearts Project

The helping Little Hearts project investigates the use of physical activity participation and exercise training in children with congenital heart defects. Most children with a surgically corrected heart defect have near normal exercise tolerance and could safely participate in competitive sport. Individuals with more complex structural defects may have significantly reduced exercise tolerance and functioning, but would still benefit from participating in physical activity in a recreational environment. However, evidence suggests that many children are underactive due to self-perceptions and parental anxiety.

This project is funded by the Leeds-based charity Heart Research UK, with the main objective of developing a comprehensive set of advice and recommendations to enable children with a heart defect to safely engage in sports and other physical activities. An exercise ‘prescription‘ toolkit has been successfully piloted in six UK cardiac centres, and is now being rolled out nationwide to all UK paediatric cardiac centres, such as Great Ormond Street and Belfast hospitals.

This ‘Toolkit‘ includes interactive resources for youngsters, their parents/carers and schools. Importantly, each youngster receives their own bespoke ‘exercise prescription‘ form; detailing what level and type of activities are suitable for them. This provides their parents, school and themselves with the confidence to participate and enjoy regular physical activity; greatly improving their long-term health and well-being.

In addition to the Toolkit, we are holding conferences for health professionals and parents, such as our recent January 2016 conference for clinicians on ‘Exercise Prescription in Congenital Heart Disease’. These aim to involve all parties and make sure they have access to the knowledge and information necessary to drive exercise prescription in congenital heart disease forward.
