Dr Penny Rumbold is an Associate Professor in Exercise Nutrition in the Department of Sport, Exercise and Rehabilitation at Northumbria University. Research and teaching interests lie primarily in the promotion of nutritional strategies to improve metabolic health in both adult and paediatric populations. Through her PhD work Penny focused on energy and appetite regulation in young athletes, specifically exploring the appetite and energy intake responses to netball-specific exercise in adolescent girls, under ‘free-living’ conditions. Since completing her PhD in 2010, Penny has been successful in gaining research funding from various industry partners (Dairy Council; Nourishmenow; Cool Milk) to fund one of her research interests focussed around the influence of milk and other dairy products on energy and appetite regulation in females, but also primarily in paediatric populations. Additional research interests also include the influence of active video games on appetite and energy intake in paediatric populations. Most recently Penny has been working collaboratively with local football academies (NUFC) to explore the implementation of nutritional interventions for supporting metabolic health in adolescent-academy football players. Currently this work involves profiling various sources of stress (e.g. high intensity training loads; growth and maturation; severe energy deficits) using measures of thyroid status, that adolescent-academy footballers are exposed to, which may potentially be promoting poor metabolic health. The findings of the profiling exercise will then inform acute and chronic nutritional interventions and educational strategies to facilitate restoration and maintenance of good nutritional practices and metabolic health in adolescent-academy footballers. Penny also works proactively to develop collaborative relationships with local primary and secondary schools to advise on nutritional practices to promote health in young people.
