Abstract

The purpose of this exploratory analysis was to examine the effects of resistance training (RT) on leukocyte telomere length in breast cancer survivors. Samples from 33 breast cancer survivors were analysed following a 16-week RT or usual care intervention (RT: n = 19, control: n = 14). The RT group performed supervised exercise three times per week. Leukocyte telomere length was assessed before and after training using quantitative PCR. Changes in telomere length were analysed using ANCOVA, with the change score being the dependent variable, and the baseline value the covariate. Effect sizes (ES) were calculated via partial eta squared. We found a non-statistically significant change in telomere length, and a small associated ES in the RT group compared to the control group for change in telomere length (p = 0.78, ES = 0.003). Our exploratory study demonstrates that a 16-week RT intervention does not have a significant effect on telomere length in women recovering from breast cancer. Therefore, RT is a safe intervention that does not accelerate biological ageing.
