Abstract
Background: Age-related decline in sleep quality and functional strength significantly affects independence and quality of life in older adults. Blood flow restriction (BFR) training has emerged as a low-load exercise approach that may improve muscular and functional outcomes and may also benefit sleep, compared with conventional exercise programs.
Objective: To evaluate and compare the effectiveness of blood flow restriction training and conventional exercise on sleep quality and functional strength in older adults.
Methods: A quasi-experimental study was conducted among older adults who were allocated into two groups: Group A received blood flow restriction training, and Group B underwent conventional exercise training. Both interventions were administered over a structured training period. We assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and functional strength using the Short Physical Performance Battery (SPPB). We recorded and analysed pre- and post-intervention measurements.
Results: Both groups improved in sleep quality and functional strength, but the BFR group showed greater improvement in PSQI and SPPB scores than the conventional exercise group.
Conclusion: BFR training was more effective than conventional exercise in improving sleep quality and functional strength in older adults.
