The Effect of Blood Flow Restriction Training on Core Muscle Strength and Pain in Male Collegiate Athletes with Chronic Nonspecific Low Back Pain
Provisionally accepted- Institute of Physical Education Shanxi University, Taiyuan, China
The objective of this study is to compare the effectiveness of low-load blood flow restriction training (LL-BFRT) to heavy-load resistance training (HL-RT) in male collegiate athletes with chronic non-specific low back pain (CNLBP). METHODS: Twenty-six participants were randomly assigned to LL-BFRT (n=13) or HL-RT (n=13). 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 t-tests. RESULTS: Pain intensity and function disability level in LL-BFRT had extremely significant improvement at 4 weeks (p<0.001, ES=1.44-1.84). Participants in LL-BFRT and HL-RT showed significant differences in core extensors peak torque-body weight ratio (PT/BW) at isokinetic 120°/s and 30°/s, respectively
