Introduction
I live and work in a beautiful part of the world, surrounded by the Australian countryside. I hold the Chair of Applied Physiology in the School of Allied Health, Exercise & Sports Sciences. I have been working on theoretical papers exploring the basis on which we understand fatigue in a range of conditions. My current projects include pacing in older people, in diseased states and the perception of pain as a threshold for human performance.

The extent of smoking history is causally linked to adverse cerebro‐ and cardiovascular health outcomes, while conversely, exercise decreases this risk and associated mortality. However, the acute cerebro‐ and cardiovascular responses to exercise in smokers are unknown, and may provide insight to understand chronic adaptation. This study examined t...
Article
Full-text available
Maintaining optimal physical and cognitive performance are keys to success for most exercise contexts. However, consensus on the effects of dehydration for cognitive function is equivocal, particularly given the addition of confounding variables when hypohydration (HYPO) results. Therefore, this study aimed to examine whether maintaining euhydratio...
Article
This study examined the acute effects of combined tobacco smoking and exercise on immune-inflammatory responses in smoker populations with shorter or longer smoking history. The cohort comprised 14 young male adult (YSM) and 12 middle-aged (MSM) male active cigarette smokers matched for aerobic fitness and smoking behavior. Following an initial fam...
Article
Hypohydration is generally considered to have a negative effect on cognitive function, despite several studies reporting comparable findings between hydration states. Recommendations to avoid moderate dehydration (≥ 2% loss in body mass) are commonly made to athletes, on the provision that this deficit may impair optimal cognitive performance. To d...
Article
New findings: What is the central question of this study? High-intensity interval exercise (HIIE) is recommended to be avoided within 4 h of bedtime due to potential sleep disruptions which may affect appetite-related hormone interactions and subsequent energy intake. Yet, the interactions between sleep and appetite following early evening HIIE ha...
Article

The present study aimed to identify whether or not the release of interleukin (IL)-6 and soluble (s) IL-6 receptor (R) is associated with fatiguing behaviour and changes in cortical activity during self-paced exercise. Relationships between the IL-6 and its soluble receptors, total work, reductions in power output, and changes in slow, alpha (α) an...
Chapter
The relationship between performance, heat load and the ability to withstand serious thermal insult is a key factor in understanding how endurance is regulated. The capacity to withstand high thermal loads is not unique to humans and is typical to all mammals. Thermoregulation is an evolutionary adaptation which is species specific and should be re...
Conference Paper
Full-text available
The contextual interference (CI) effect, where high CI conditions suppress practice performance but then enhance delayed test performance, appears to extend beyond motor planning to also involve executive processes. As this implies a role for prefrontal cortex (PFC) activation in the CI effect, the present experiment utilized two-channel near-infra...
Article
This study examined immune/inflammatory parameters following an acute tobacco smoking episode in smokers with varying smoking histories. Twenty-eight male habitual smokers were categorized according to smoking history, e.g. younger smoker (YSM) or middle-aged smoker (MSM). Participants were matched for fitness and smoking habits and following basel...

Article
Full-text available
The involvement of the brain in exercise regulation is not a particularly new concept and the fact the motor cortex (MC) is not activated maximally at exhaustion is suggestive that there are pathways upstream of the MC (10), regulating exercise and effectuating termination. Several papers have now addressed the areas of the cortex that are activate...
