Abstract

ABSTRACT: The aim of this study was to assess the effects of concurrent biomechanical biofeedback on the ability of novices to modify relative knee, spine, and elbow motions during a rowing-type task. After six non-instructed practice sessions, novices were assigned to a biofeedback (BFb; n = 7) or control group (Con; n = 7), before six, ten-minute sessions of continuous rowing were performed over 2 weeks. The BFb group received concurrent, visual biofeedback for developing sequential timing of knee, spine, and elbow motions during the pull. Following the intervention, the BFb group demonstrated delayed elbow flexion initiation (pre-intervention, 46 ± 11% pull; post-intervention, 78 ± 3% pull; p = 0.001). The biofeedback further promoted the consecutive ending of joint rotations (BFb: knee, 69 ± 4% pull; spine, 73 ± 7% pull; elbow, 85 ± 3% pull; Con: knee, 79 ± 8% pull; spine, 28 ± 6% pull; elbow, 79 ± 4% pull) and a move towards the sequential sequencing pattern. Concurrent biomechanical biofeedback during short-term training altered technique, possibly by providing guidance towards the desired movement pattern and increasing error detection and correction capabilities.
