Career Summary

Biography

I am an accredited exercise physiology having completed undergraduate studies in Human Movement at Wollongong University before undertaking a Masters degree in Exercise Physiology at South Cross University. I have always been interested in the integration of different exercise physiological, environmental and nutritional factors in sport, human movement and health. My research interests and accomplishments have channeled the focus of integration of multidisciplinary areas and specialisations in exercise and medical sciences.

At the time I was completing Masters studies, I was involved in the sport of triathlon and wondered about how resistance training could impact endurance performance. Aside from gaining a sound foundation of knowledge and experiences in neuromuscular fatigue, I learnt about the fundamentals of resistance training and how muscles get bigger that I have applied in practice the elderly and in sporting populations. The research I undertook examined how resistance training can impact endurance performance. I have since published research on how resistance training can improve endurance performance but also shifted my intention to functional exercise training to correct and prevent overuse injuries common with high training loads.

I completed PhD studies at the University of Bath in the United Kingdom before undertaking post doctoral studies in molecular muscle biology at Copenhagen University, Denmark (interaction between exercise and High Fat feeding) and The University of Montpellier, France (Intermittent Hypoxia Training). These studies gave me an awareness of what is possible with sound collaboration and innovation. I have learnt techniques and gained knowledge in muscle cell biology that I have applied in practice and research. I have a firm interest in how our genetic profile impacts exercise adaptation and musculoskeletal injury manifestation. I have continued to research how nutritional interventions combined with different exercise result in heightened changes in physiological functioning.

I have held academic positions at the University of NSW, School of Medical Science and the University of Adelaide, Medical Sciences. I have a keen interest in integrated health and medical education especially concerning musculoskeletal medicine. Over the last decade embraced the concept of e learning and have explored how traditional face to face learning and assessment can be complimented by electronic resources thereby promoting flexible learning options. Whilst in Adelaide I completed further studies in Pain Sciences which had a profound impact on my outlook to human physiological functioning, exercise and health. The manifestation of pain is a multifactorial and complicated aspect of health care. The effects of graded exercise in acute pain arising from injury has become a strong interest.

PURPOSE: This investigation examined the ergogenic effect of short-term oral N-acetylcysteine (NAC) supplementation and the associated changes in redox balance and inflammation during intense training. METHODS: A double-blind randomized placebo-controlled crossover design was used to assess 9 d of oral NAC supplementation (1200 mg·d) in 10 well-trained triathletes. For each supplement trial (NAC and placebo), baseline venous blood and urine samples were taken, and a presupplementation cycle ergometer race simulation was performed. After the loading period, further samples were collected preexercise, postexercise, and 2 and 24 h after the postsupplementation cycle ergometer race simulation. Changes in total antioxidant capacity, ferric reducing ability of plasma, reduced glutathione, oxidized glutathione, thiobarbituric acid-reactive substances, interleukin 6, xanthine oxidase, hypoxanthine, monocyte chemotactic protein 1, nuclear factor ¿B, and urinary 15-isoprostane F2t concentration were assessed. The experimental procedure was repeated with the remaining supplement after a 3-wk washout. Eight participants completed both supplementation trials. RESULTS: NAC improved sprint performance during the cycle ergometer race simulation (P < 0.001, ¿p = 0.03). Supplementation with NAC also augmented postexercise plasma total antioxidant capacity (P = 0.005, ¿p = 0.19), reduced exercise-induced oxidative damage (plasma thiobarbituric acid-reactive substances, P = 0.002, ¿p = 0.22; urinary 15-isoprostane F2t concentration, P = 0.010, ¿p = 0.431), attenuated inflammation (plasma interleukin 6, P = 0.002, ¿p = 0.22; monocyte chemotactic protein 1, P = 0.012, ¿p = 0.17), and increased postexercise nuclear factor ¿B activity (P < 0.001, ¿p = 0.21). CONCLUSION: Oral NAC supplementation improved cycling performance via an improved redox balance and promoted adaptive processes in well-trained athletes undergoing strenuous physical training. © 2014 by the American College of Sports Medicine.
