A sporting chance at science
Dr Nattai Borges found the perfect way to combine a love of sport with a fascination for science – and the Central Coast campus is the beneficiary.
It’s not often that you can combine two disparate passions into one career path, but Nattai has managed to achieve just that. With a love for science sparked in early high school, and a life-long sporting background it’s no wonder that Nattai was drawn to Exercise and Sports Science.
“At the time the other potential study options were physiotherapy or medicine, but Exercise and Sports Science was perfect for me,” Nattai says. “I’m glad I found it.”
Nattai practices what he preaches, ensuring he spends time working in industry along with teaching and researching. “This way I can ensure that I never lose the vision of ‘well, this is the science, but how can we apply that science and make it more meaningful to the general population, the athletic population and the disease-state population?”
“I like to bridge the division between the mechanistic ‘bench science’ of exercise physiology and the more translational applied research,” Nattai says. “Human physiology is such a complex and continually interchanging environment. If we ask ‘What causes fatigue during exercise?’ there’s no simple answer.”
Having worked as an accredited exercise physiologist in the muscular-skeletal rehab area, Nattai has an anatomical insight into sports science and the role that exercise plays in wellbeing. “I’ve also worked as a strength and conditioning coach for a number of sporting teams and in private clinics working with young athletes,” Nattai says. “It’s been fun and has given me a really applied background that can help make the theory I’m teaching be more practical for my students. They really respond well to it.”
This has also given Nattai insight into the strength and conditioning and applied sport science areas. “This insight has led me to perform research into understanding match demands of sports such as basketball and cricket and monitoring hydration status in rugby union,” says Nattai.
Ageing and exercise
Exploring the role that exercise plays in maintaining health and fitness as we age is one of Nattai’s research focuses, but one challenge is to accurately measure the impact of physical activity on ageing. “As we get older and busier (during our twenties and thirties!) our levels of physical activity tend to drop, so if we study sedentary older and younger people we’re not really factoring for that drop in physical activity. But if we look at two groups of people who’ve maintained physical activity we gain real insight.”
In his research Nattai’s been comparing master’s athletes with younger athletes to garner a better understanding of what the actual ageing process is, by factoring in the impact of maintaining fitness.
“It’s an emerging field of research at the moment,” Nattai says. “Mainly because there aren’t that many Masters Athletes to work with, and these athletes tend to focus on endurance sports. But what we’ve seen so far shows that if you keep exercising, you can keep performing. It shows the adaptability of the body as you age.”
However, Nattai stresses that we also need to examine the role of nutrition in fitness and ageing. “Older people tend not to digest protein as well, so their ability to synthesise new muscles is impacted. Consuming high-quality protein is also important to help mitigate health risks.”
As we age, there is a decrease in muscle mass known as sarcopenia, especially in our power-based muscle fibres or type-2 muscles fibres. “We need to explore whether we should be focussing on different types of training which maintain our type-2 muscle fibres. We know that endurance training doesn’t help maintain our power-based muscle, we need to focus on resistance training, plyometric training and to also focus on nutrition alongside training.”
Nattai stresses that it’s not just from an exercise perspective that we need to focus on muscle mass as we age – it’s also important from a quality-of-life perspective: “Muscles are one of our largest organs and one of the most important,” Nattai says. “We’re only starting to scratch the surface in terms of the signalling role that muscles play with hormones and the maintenance of our muscle mass.”
Acting local, thinking global
Working with Central Coast sporting groups is just one of the ways that Nattai is looking to connect his research with locals. “I bring the lessons learned from playing in team sports into all aspects of my life,” Nattai says.
“I’m aiming to work with local sporting teams here on the central coast to help bring the knowledge from the University into our sporting clubs,” says Nattai who’s currently playing with the local Avoca FC.
Exploring the link between fitness and wellbeing is also on Nattai’s radar, and he’s actively seeking industry collaborations to apply his research in the field. “An emerging theme in research is the role that exercise can play in managing the symptoms and side-effects of cancer. Research seems to indicate that there are some potential benefits of combining certain types of exercise with treatment – and it’s an area I’d like to explore.”
A proficient science communicator, Nattai has already received an International accolade for his oral presentation skills while undertaking his PhD. “In 2016 I won a prestigious international award at the European Congress of Sports Scientist,” Nattai proudly states. “I was selected in the top 4 before being asked to perform before the whole congress where I was awarded the Young Investigators Award.”
At this congress in Vienna, Nattai spoke to global professionals about one of his PhD projects which researched the effects of age on pulmonary and muscular oxygenation following high intensity training. And Nattai feels that his work in this space hasn’t concluded now he’s been awarded his PhD. “I’d love to keep developing the work I did in my PhD and explore healthy ageing and exercise and the benefits for the ageing Australian population.”
Nattai has recently graduated from his doctoral studies investigating the influence of age on fatigue and recovery in cyclists where he created several testing protocols to holistically monitor the fatigue state and recovery in his testing participants. Nattai has also acquired substantial clinical and sports industry experience both in Australia and Overseas over the past 10 years which has given him a broad perspective in the areas of exercise prescription, programming and sport science. Nattai has been an Accredited Exercise Physiologist since 2010 with experience working in return to work programs as well as a strength and conditioning coach in both private clinics and for established rugby and football teams. Currently, Nattai’s research mainly revolves around investigating the physiological basis fatigue and recovery as well as understanding the match demands for team sports in an attempt to improve health and performance. Nattai has a strong publication record, has presented at a number of national and international conferences and was recently awarded the 2016 European College of Sport Sciences prestigious Young Investigator Award for his research into the influence of age on fatigue states in cyclists. Nattai would like to continue his current research in fatigue and recovery by investigation causative mechanisms of fatigue as well as novel techniques to improve recovery without attenuating training adaptation.

© 2018 Taylor & Francis Group, LLC Background: The purpose of this study was to compare physical performance, perceptual and haematological markers of recovery in well-trained masters and young cyclists across 48¿h following a bout of repeated high-intensity interval exercise. Methods: Nine masters (mean ± SD; age¿=¿55.6¿±¿5.0¿years) and eight young (age¿=¿25.9¿±¿3.0¿years) cyclists performed a high-intensity interval exercise session consisting of 6¿×¿30¿s intervals at 175% peak power output with 4.5¿min rest between efforts. Maximal voluntary contraction (MVC), 10¿s sprint (10SST), 30-min time trial (30TT) performance, creatine kinase concentration (CK) and perceptual measures of motivation, total recovery, fatigue and muscle soreness were collected at baseline and at standardised time points across the 48¿h recovery period. Results: No significant group-time interactions were observed for performance of MVC, 10SST, 30TT and CK (P¿>¿0.05). A significant reduction in 10SST peak power was found in both masters (P¿=¿0.002) and young (P¿=¿0.003) cyclists at 1¿h post exercise, however, both groups physically recovered at similar rates. Neither group showed significant (P¿>¿0.05) or practically meaningful increases in CK (%¿ < 10%). A significant age-related difference was found for perceptual fatigue (P¿=¿0.01) and analysis of effect size (ES) showed that perceptual recovery was delayed with masters cyclists reporting lower motivation (ES ±90%CI¿=¿0.69¿±¿0.77, moderate), greater fatigue (ES¿=¿0.75¿±¿0.93, moderate) and muscle soreness (ES¿=¿0.61¿±¿0.70, moderate) after 48¿h of recovery. Conclusion: The delay in perceived recovery may have negative effects on long-term participation to systematic training.
