Hidden dangers of exercise


James Cook University Sports and Exercise Science PhD candidate Amanda Geraghty is studying oxidative stress, a condition that can be brought on by exercise, is when the body is overwhelmed by the production of harmful free radicals.

Amanda’s project aims to develop exercise guidelines that will reduce the risk of the developing oxidative stress.

“Whilst the direct relationship has not been determined, free radicals can contribute to the onset of cardiovascular and neurological diseases and cancer and can accelerate aging,” Amanda said.

“Both trained and untrained individuals have been shown to experience oxidative stress. However, regular exercise has been shown to strengthen the resistance to this process.”

“My research will provide insight into whether exercise can be tailored to emphasise the positive adaptation,” she said.

Amanda is searching for healthy adult men who exercise once or twice a week to take part in her study.

“Volunteers will be required participate in two to four exercise sessions for a four week period. Physiological analysis will involve measures of general health and fitness, as well as free radical and antioxidant levels,” she said.

“The aim of this study is to develop exercise guidelines which ultimately promote health and reduce free radical formation.”

But do not be too hasty is hanging up the joggers. The benefits of regular exercise and a balanced diet outweigh the risk that exercise may have a negative impact.

“It would be a good reason not to exercise when the treadmill is not an appealing option, but it is important to continue exercising, particularly when considering the serious implications of a sedentary lifestyle.”
