Combining blood flow restriction with eccentric resistance training significantly enhances lower limb explosive strength, speed, and anaerobic capacity in collegiate sprinters compared to eccentric training alone.
This study examined the impact of eccentric exercise (ECC) training combined with blood flow restriction training (BFRT) on explosive power in the lower extremities. Sixteen collegiate sprinters were randomly allocated into two groups: the BFRT group, comprising eight male participants, and the ECC group, also consisting of eight men. Participants in the ECC group engaged in eccentric exercises thrice weekly for a duration of six weeks. Alongside the ECC training, participants in the BFRT group had a pressure cuff positioned on the proximal thigh, sustaining a pressure of 150 mmHg. Assessments were performed before and after training to examine hip joint strength, physical fitness (assessed through a 30-meter sprint and vertical jump), anaerobic capacity, and lower limb circumference. The findings indicated that both the ECC and BFRT groups displayed notable enhancements in the isokinetic strength of the hip extensors, with the BFRT group achieving superior results relative to the ECC group. Moreover, BFRT was observed to improve muscle strength on the non-dominant side, consequently diminishing strength asymmetry between both sides. Both training methods enhanced the leaping ability and speed of the collegiate sprinters; however, the BFRT group demonstrated superior efficacy in improving jumping performance. Furthermore, both groups enhanced anaerobic ability and the limb circumference of the lower limb muscles, with BFRT demonstrating more significant advantages than ECC alone. The data indicate that the regular integration of ECC training with BFRT results in superior improvements in lower limb explosiveness, anaerobic capacity, and muscular circumference compared to ECC training performed alone.

Liu et al. (2026) conducted an RCT in Healthy male collegiate sprinters (n=16). Blood flow restriction training (BFRT) combined with eccentric exercise (ECC) vs. Eccentric exercise (ECC) alone was evaluated on Right hip extensor peak power (Hedges' g 1.42, 95% CI 0.44-2.40, p=<0.001). Blood flow restriction combined with eccentric resistance training significantly improved right hip extensor peak power (Hedges' g 1.42) and lower limb explosiveness in male collegiate sprinters compared to eccentric training alone.
