Acute Effects of Aerobic Exercise and Relaxation Training on Fatigue in Breast Cancer Survivors: A Feasibility Trial
Mené sur 40 patientes ayant survécu à un cancer du sein, cet essai randomisé à 3 bras évalue l’intérêt d’une intervention à base d’exercices physiques en aérobie et de relaxation pour soulager leur fatigue
Objective : This three?armed randomized controlled feasibility trial tested the acceptability and acute effects of aerobic exercise and technology?guided mindfulness training (relative to standalone interventions) on cancer?related fatigue among breast cancer survivors (BCS). Methods : BCS recruited from Central Illinois completed pre?and post?testing using established measures and were randomized to one of three groups (combined aerobic exercise with guided?mindfulness relaxation, aerobic exercise only, relaxation only), conducted in three 90?minute sessions over the course of seven days in a fitness room and research office on a university campus. Results : We enrolled 40 BCS (Mage = 57.33 ± 8.75), MBMI = 27.38 ± 5.27, Mfatigue = 4.56 ± 1.81 as measured by the Piper Fatigue Scale). More favorable post?intervention evaluations were reported by the combined group, compared to aerobic exercise or relaxation only (p < 0.05). Reductions in fatigue favoring the combined group (p = 0.05) showed a modest effect size (Cohen's d = 0.91) compared to aerobic exercise only. Conclusions : These findings provide preliminary evidence for the feasibility of combining evidence?based techniques to address fatigue among BCS. The combined approach, incorporating mobile health technology, presents an efficacious and well?received design. If replicated in longer trials, the approach could provide a promising opportunity to deliver broad?reaching interventions for improved outcomes in BCS.
