All participants supervised exercises (deep-squat, lateral pull-down, bench-press and machine seated crunch) cycled 4 times per week for 4 weeks (16 sessions). LL-BFRT was done at 30% 1-repetition maximum (1RM) with 70% arterial occlusion pressure (AOP). HL-RT was done at 70% 1-RM. The outcomes were isokinetic core strength, isometric core endurance, pain intensity, and lumbar function disability level, measured at baseline and 4 weeks. Intra-group differences were evaluated using <jats:italic>t<\/jats:italic>-tests.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Pain intensity and function disability level in LL-BFRT had extremely significant improvement at 4 weeks (<jats:italic>p<\/jats:italic> &amp;lt; 0.001, ES = 1.44\u20131.84). Participants in LL-BFRT and HL-RT showed significant differences in core extensors peak torque-body weight ratio (PT\/BW) at isokinetic 120\u00b0\/s and 30\u00b0\/s, respectively (LL-BFRT: <jats:italic>p<\/jats:italic> = 0.045, ES = 0.62; HL-RT: <jats:italic>p<\/jats:italic> = 0.013, ES = 0.81). Isometric core extensor endurance was significantly increased in both groups (LL-BFRT: <jats:italic>p<\/jats:italic> = 0.016, ES = 0.78; HL-RT: <jats:italic>p<\/jats:italic> = 0.011, ES = 0.83).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Four weeks of LL-BFRT significantly reduced pain and functional disability while inducing similar strength gains as HL-RT in male collegiate athletes with CNLBP.
