Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Firstly, participants will be randomly allocated, using a digital software, to aerobic or resistance training group.
After one week of familiarization where participants will be guided to the exercise training session with an accredited exercise physiologist, participants will perform a single bout of resistance training at moderate to high intensity for approximately 60 minutes under supervision of accredited exercise physiologist, 1 to 1 in the gym (acute session 1). Intensity will be measured using rating perceived of exertion 0-10, % of repetition maximum. For the resistance training, machine-based exercises including chest press, leg press, seated row, leg curl, push press, leg extension, pull down, lunges will be used.
One week after, participants will commence a 12-week of resistance training, 3 times per week for 60 minutes, with an intensity ranging from moderate to high, under supervision of accredited exercise physiologist in small groups in the gym (3 to 4 participants) (chronic intervention). Intensity will be measured using rating perceived of exertion 0-10, % of repetition maximum. Adherence will be monitored using a checklist. For the resistance training, machine-based exercises including chest press, leg press, seated row, leg curl, push press, leg extension, pull down, lunges will be used.
Lastly, one week after the conclusion of the 12-week of training program, participants will perform another single bout of resistance training at moderate to high intensity for approximately 60 minutes under supervision of accredited exercise physiologist 1 to 1 in the gym (acute session 2). Intensity will be measured using rating perceived of exertion 0-10, % of repetition maximum. For the resistance training, machine-based exercises including chest press, leg press, seated row, leg curl, push press, leg extension, pull down, lunges will be used.

Statistical methods / analysis
All data will be analysed using SPSS (version 25.0; SPSS, Inc., Armonk, NY). Normality will be analysed using the Shapiro-Wilk test. Studies 1 and 3, acute exercise sessions: Repeated measures ANOVA (or Freidman’s ANOVA for data not normally distributed) will be used to calculate within-group differences in myokine expression and cancer cell growth and proliferation from pre- to post-intervention, while group x time repeated measures ANOVA will be used to calculate between-group differences (data not normally distributed will be log transformed). Study 2, chronic training intervention: For baseline comparisons, independent t-tests or the Mann-Whitney U test will be used for continuous data, as appropriate, and Chi-square for categorical variables. Group x time repeated measures ANOVA or ANCOVA (with log transformation for data not normally distributed) will be used to calculate between-group intervention effects on myokines, cancer cell growth and proliferation, body weight and body composition, maximal strength, VO2max and QoL questionnaires, while paired samples t-tests or the Wilcoxon signed-rank test, as appropriate, will be used for within-group changes. Pearson or Spearman rank correlation analysis will be used to calculate the association between changes in body composition parameters and myokine levels. Tests will be two-tailed, and a p-value of 0.05 will be considered statistically significant.

Summary
Brief summary
The aim of this project is to explore the effects of an acute bout of exercise (before and after a training intervention) and the chronic effects of a 12-week resistance vs aerobic training program on acute and resting expression of signalling proteins, known as myokines, and their cancer-suppressive effects, in relation to body composition, in breast cancer survivors.

Who is it for?
You may be eligible for this study if you are a woman with stage I-III breast cancer who has completed primary treatment at least 4 months prior to commencing this trial, and have been medically cleared for exercise.

Study details
Participants will be randomly allocated to a 12-week exercise program involving either resistance or aerobic training. In the weeks immediately before and after the 12-week program, participants will also complete an acute bout of exercise. Participants will be asked to provide blood and complete questionnaires and physical testing before and after the acute bouts of exercise and 12-week program.

It is hoped that findings from this study shed light into the mechanisms behind exercise's effect on breast cancer management.
