Exercise, Bioactive Ingredients and Metabolic and Vascular Health

About us

We are interested in the effect of exercise and bioactive ingredients on metabolic and vascular health.  The form of exercise we have examined has mainly been interval sprinting which we have shown brings about positive acute and chronic changes in body composition, autonomic, and cardiovascular function. Bioactive ingredients studied include green tea, fish oils, and saturated fat.

Current projects are focused on:

  • Interval sprinting & body composition: Interval sprinting exercise is a time-efficient form of exercise which consistently results in more total and visceral fat loss and greater reductions in insulin resistance than conventional exercise e.g. walking and jogging.
  • Interval sprinting & green tea: We have recently shown that ingesting green tea before interval sprinting increases fat oxidation at rest and after exercise of young men and women.
  • Interval sprinting & postprandial lipemia: Recently, we have shown that 20 minutes of interval sprinting in the early evening reduced fat in the blood of women who ate a high fat meal the next morning.
  • Exercise & autonomic & vascular function: The effect of exercise on autonomic and vascular function is important to investigate as overweight adults and individuals with a family history of hypertension typically possess limited vasodilatory and degraded autonomic function
