My main area of interest is in the health benefits of high-intensity interval training (HIT), a novel, time-efficient exercise intervention for improving insulin sensitivity and aerobic fitness. From an applied perspective we hope this research will lead to an alternative means to reap the health benefits of exercise for individuals who currently perceive lack of time as a barrier to performing sufficient physical activity. Furthermore, although rapid progress is being made in identifying the range of health benefits associated with an active lifestyle, we are still lacking in understanding of the link between performing physical activity and achieving beneficial adaptations. By using HIT as an alternative model of exercise instead of traditional aerobic training we hope to develop a clearer understanding of the mechanisms of beneficial adaptations to exercise. We make use of the phenomenon of low and high responders to exercise to further elucidate the mechanisms of adaptation. As an example, we have used gene expression analysis to determine a method enabling us to predict whether individuals will adapt to training prior to starting the training programme, an important step towards personalised medicine.
