Background

Brendon Roxburgh is a Lecturer in Clinical Exercise Physiology at the School of Physical Education, Sport and Exercise Sciences. Brendon obtained his BPhED (2008) at Otago before completing an MSc (Sport and Exercise Science) at the University of Auckland.

He worked as a clinical exercise physiologist for more than 10 years, specialising in cardiopulmonary exercise testing and exercise-based rehabilitation for people with cardiovascular disease. In 2018 he returned to the University of Otago to complete a PhD on prehabilitation – optimising patient fitness before surgery.

Brendon has been awarded a Lottery Health Postdoctoral Fellowship and a Health Research Council Emerging Researcher Grant. He has also received research funding from Pūtahi Manawa, Arthritis New Zealand, Maurice and Phyllis Paykel Trust, the National Heart Foundation, HeartOtago, Cardiac Society of Australia and New Zealand, and the University of Otago.

Research

Brendon’s research interests include:

The role of exercise during presurgical cancer treatment (neoadjuvant therapy) to improve patients’ tolerance to chemotherapy, reduce treatment-related side effects, and enhance tumour shrinkage before surgery.
The role of hot-water immersion for improving health. Brendon has a number of ongoing studies looking at the effect of hot-water bathing on blood pressure, as a therapy for people with hypertension. He is also looking at the effect of hot-water bathing on joint pain in people with arthritis.
The role of fitness in patients scheduled for surgery. Fitter patients are more resilient to the stress of surgery and therefore have better outcomes and recovery following surgery. Brendon’s research looks at novel ways for improving fitness before surgery, to optimise postoperative recovery.
Thermoregulatory responses and strategies in athletes, with a particular focus on motorsport athletes and open-water swimmers. His work examines how heat stress affects performance, safety, and recovery in these unique sporting environments.
Other research interests include:
1. Cardiopulmonary exercise testing and other forms of fitness assessment
2. Exercise-based cardiac rehabilitation
3. High-intensity interval training
4. Isometric exercise training for lowering resting blood pressure
