Unilateral resistance training has been shown to promote strength adaptations in the directly trained limb and also improve strength in the contralateral limb, a phenomenon known as cross-education (CE), with more pronounced effects observed in high-load training. However, high-load resistance training may be unfeasible for older adults. Blood flow restriction (BFR) training emerges as a low-load alternative that reduces joint stress, is easy to apply, and has low cost. Although there is already evidence showing significant effects of CE during resistance training with BFR, gaps remain regarding its applicability in older adults. This study aims to evaluate the effects of CE in resistance training with BFR on the lower limbs of older women.
