Dr Deborah Dulson’s current research interests focus on the influence of caffeine on immune responses following strenuous exercise. Deborah has investigated the effects of both high and low doses of caffeine on immune function both at rest and following cycling in endurance trained athletes. She has also looked into the effects of single versus repeated doses of caffeine on the effects of immune function following intermittent exercise.
As well as being interested in the effects of caffeine, Deborah is also interested in the effect of other nutritional interventions on immune function in both individual and team sport athletes following a range of different exercise protocols. Deborah’s research into nutrition and exercise immunology is a mix of both fundamental and applied research and is inter-disciplinary in nature, lying at the intersection between immunology, physiology, biochemistry and nutrition.
Current Research Projects
- The hormonal, inflammatory and molecular response to con-current repeated-sprint and resistance exercise in female team-sport athletes - with PhD student Jessica Dent.
- Caffeine, salivary IgA responses and high intensity exercise – with Masters student Chloe Smith.
