Biographical details

Rhonda’s research interests have evolved from her industry and clinical experience as a Pharmacist, and integrated with Master’s and Doctoral studies in exercise and sport science. Her PhD investigated the efficacy of power (resistance) training on muscle function, balance physical capacity and psychosocial function in healthy elderly. The interest in whole body vibration exercise developed as another modality that might provide benefits to muscle function and balance. Rhonda’s interest in drugs and sport stemmed from her pharmacology background. It commenced with investigating the effect on caffeine on exercise performance and progressed to the wider issues of doping and performance enhancement in elite sport. Recent research has continued in elite sport to investigate the physical demands of and injuries sustained in elite rugby league through measurement and analysis of performance and training.

Research interests

Drugs in sport and anti-doping issues associated with high performance sport. Performance analysis and physical demands of elite rugby league. Injury surveillance in elite developing athletes. Resistance training and balance in seniors. Whole body vibration exercise

Rhonda is a member of the Exercise for Health Promotion, Disease Prevention and Treatment research team:

Teaching and supervision

Rhonda is the Unit of Study Coordinator for EXSS3037 Exercise Pharmaology and Immunology in the B Appl Sc (Exercise and Sport Science) and B Appl Sc (Exercise Physiology) degrees, as well as EXSS5064 Nutrition and Pharmacology in the Master Exercise Physiology program. She is currently supervising 5 Masters and Doctoral students whose projects cover the topics of quantifying physical and movement demands in elite rugby league players using Global Positioning Systems technology. injury surveillance in elite junior rugby league, dose response of whole body vibration in adults, dose response of resistance training and detraining in adults, and the effect of exercise on cognition and academic performance in adolescents.

Awards and honours

In 2010, Rhonda was awarded the Health Sciences Research Award at Gerontological Society of America Annual Meeting in New Orleans for: Effect of standing posture during whole body vibration training on muscle morphology and function in older adults. In addtiion, Rhonda received the Clinical Medicine Person-in-Training Award at Gerontological Society of America Annual Meeting in Orlando, Floridafor: Power training improves balance in healthy older adults, in 2005
