Taking the puff out of colorectal cancer
A researcher who was born in the year that actress Audrey
Hepburn and footballer Bobby Moore died of colorectal cancer is
helping to lead recovery from the deadly condition.
University of Queensland researcher
James Devin, 23, of the School of Human Movement
and Nutrition Sciences, has studied the
effects of exercise on colorectal cancer survivors.
"Increases in cardiorespiratory fitness are associated with a
significant reduction in cancer-specific mortality," Mr Devin
"We showed that eight weeks of high-intensity interval training
(HIIT) and moderate-intensity exercise (MIE) promoted significant
improvements in cardiorespiratory fitness in colorectal cancer
"While the comparative effectiveness was not too different, HIIT
may offer more sustained improvements following a detraining
"Encouragingly, no severe adverse events occurred as a result of
either types of training."
Mr Devin's research scored him the runner-up spot for the Young
Investigator Award at the 2016 Exercise and Sports Science
Australia (ESSA) Research to Practice Conference in Melbourne.
He collaborated with UQ's Associate
Professor David Jenkins, Dr Kate
Bolam, Dr Tina
Skinner, Andrew Sax and Gareth Hughes.
The team monitored 35 colorectal cancer survivors as they
undertook three sessions of exercise a week using either HIIT or
HIIT consisted of four rounds of four minutes of exercise at
85-95 per cent of maximum heart rate, and MIE consisted of 50
minutes of work at 70 per cent of the maximum heart rate.
"Those who undertook HIIT significantly improved and maintained
a 4.2 millilitres per kilogram per minute increase in
cardiorespiratory output even after four weeks of detraining," Mr
"The MIE group also significantly improved, but lost gains more
rapidly over the detraining period.
"To put it in perspective, a 3.5 millilitres per kilogram per
minute increase is associated with a 10 per cent reduction in
mortality risk, so the improvements we have observed appear to be
quite clinically significant for survivors."
Results of the research are published in the
Journal of Cancer Survivorship.
Other UQ researchers who received awards at the ESSA Research to
Practice Conference included Vince Kelly, Kirstin Morris and Justin
Mr Kelly won an award for a presentation on training
periodisation in the National Rugby League, while Ms Morris
revealed findings on the efficiency of varying freestyle swimming
Mr Holland was recognised for the Best Oral Presentation in
Sports Science, discussing whether fluid loss by athletes could be
detected by analysing tears.
