Impact of aerobic and heavy resistance exercise on fitness and emotions breast cancer survivors experience cancer-related tiredness

Objective: This study examined how two simultaneous supervised exercise programs affected breast cancer survivors with initial tiredness.Methodology: Thirty twofemale breast cancer survivors, aged 49 ± 4 years, were randomly assigned to aerobic (n = 16) or heavy resistance exercise (n = 16) exercise programs. Both pro-grams included eighteen weeks of resistance training, but the aerobic component in the former was more vigorous and supervised, with a perceived exertion rating of 7–8, compared to 6 for the heavy resistance exerices interventions. Most of the study addressed felt weariness. Base-line and eighteen weeks endpoints were measured. The Bonferroni correction for multiple comparisons placed the statistical significance level at 0.004.Results: The aerobic and heavy resistance exercise program reduced waist circumference (p = 0.035) and other anthropometric parameters (p = 0.029). Elevated p values in pre-and post-intervention comparisons show that aerobic exercise did not provide these advantages. No sig-nificant differences were seen between therapies, since all p values surpassed 0.004.Conclusions: In breast cancer survivors, further research is needed to determine if concurrent heavy resistance exercise is better than aerobic
