Low Load Blood Flow Restriction Training Versus Traditional Heavy Load Resistance Training in Male Athletes With Sub-acute Non-specific Low Back Pain

his randomized clinical trial aims to compare the effects of low-load blood flow restriction (LL-BFR) training and traditional heavy-load resistance training (HL-RT) on male athletes with sub-acute non-specific low back pain. Participants will be randomly assigned to either the LL-BFR or HL-RT group for a specified intervention period. Both groups will perform supervised exercise sessions targeting core and lumbar stabilizing muscles. Outcomes including pain intensity, functional disability, and muscle strength will be assessed at baseline and post-intervention. The study seeks to determine whether LL-BFR can provide comparable or superior benefits to HL-RT while reducing mechanical stress on the lumbar spine.
