SUMMARY: We investigated the effect of the intervention using the BFR method on functional capacity after 16 weeks in elderly women. In a controlled clinical trial, 23 women were randomly allocated into two groups, low-intensity exercise with blood flow restriction (LI+BFR, N = 11, age 69.40 +/- 5.73) and control group (CG, N = 12, age 69.00 +/- 6.39). The LI+BFR group had a volume of 75 repetitions at 20 to 30% of 1RM and 3 to 4 sets per exercise (30, 15, 15 and repetitions with 30" rest between sets). The CG did not undergo any type of exercise. Functional capacity, anthropometry and sarcopenia were verified through a battery of tests before and after 16 weeks. The LI+BFR group had significant improvement in performance in Handgrip strength, Chair Stand, Arm curl, 2.44 Up-and-Go and 6 min walk, Sit-and-reach and Back Scratch (p < 0.05) after the intervention. The elderly women were still classified as sarcopenic, despite the improvement in the Muscle Mass Index (p < 0.01). CG did not present significant changes. The BFR method can be an effective in the intervention process using physical exercise as an auxiliary strategy in the control of sarcopenia, providing a physical profile during the aging process.
