Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will attend a single session of resistance exercise (also known as resistance training or strength training) before starting their treatment with external beam radiation therapy; specifically, the exercise session will be performed within 7 days prior to radiation therapy commencement. The exercise session/intervention will be individually supervised by an appropriately qualified exercise professional (e.g., an Exercise and Sports Science Australia [ESSA] accredited exercise physiologist) and will be delivered face to face (in person). The exercise session will comprise 20 minutes of resistance training targeting the major upper- and lower-body muscle groups and will be performed at moderate to vigorous intensity. Resistance training will include 4-5 exercises that involve the major upper- and lower-body muscle groups, including squats, calf raises, deadlifts, and step ups (or appropriate alternatives depending on participant constitution and ability). Each resistance exercise will be performed for 2-3 sets at a load of 8-12 repetitions per set (i.e., the maximum load with which 8-12 repetitions can be performed with correct form, approximately 75% 1RM). The exercise intervention will be delivered at a medical research facility in the Perth metropolitan area. Intervention adherence will be assessed by the supervising exercise physiologist by recording the amount of completed exercise (i.e., duration, intensity, and volume).
