Dr Sarah Valkenborghs is a researcher with over 10 years of experience leading novel research on the physiological mechanisms through which exercise elicits benefits in health. She is emerging as a leader in the field of physical activity and brain health.

Her main research interests are the effects of exercise on brain structure, function and metabolism and the subsequent downstream effects on cognitive and mental health.

Dr Valkenborghs has conducted studies exploring the effects of physical activity on mental health, stress, fatigue, and cognition in a range of populations including senior high school students, men with depression, pregnant women, stroke, and multiple sclerosis. Most of these studies include the use of neuroimaging techniques such as magnetic resonance imaging (MRI) and magnetic resonance spectroscopy to elucidate neurobiological mechanisms underpinning the benefits of physical activity on brain and mental health.

In recognition that prevention is better than cure, Sarah’s current research is concentrating on the effects of physical activity on the brain during sensitive periods of development, such as in-utero (during pregnancy) and during adolescence – as these are known to impact a person’s lifelong trajectory of cognitive and mental health.
