Comparative Efficacy Of Progressive Resistance Exercises And Blood Flow Restriction Training On Lower Limb Strength And Vertical Jump In Basketball Players -An Interventional Study

Abstract

Introduction: Basketball players have traditionally used conventional strength training techniques to increase the strength and power of their lower limbs. However, these techniques frequently involve large weights and could put a lot of strain on joints, which could raise the risk of injury and need longer recovery times. One such training technique that has gained traction in recent years is Blood Flow Restriction (BFR) training^. It is a relatively new way to improve muscle growth and strength among other training methodologies. Methodology A interventional study was conducted on 60 basketball players, divided into two groups: PRE (n=30) and BFRT (n=30). Both groups underwent a 6-week training program, three sessions per week. Lower limb strength was assessed using a 1-repetition maximum (1RM) squat test, and vertical jump performance was measured using the vertical jump test. Pre- and post-intervention data were analyzed using paired and independent t-tests. Results: At the end of 6 weeks, both groups A & B showed improvements in lower limb strength. The findings indicated that both Blood Flow Restriction Training (BFRT) group showed statistically significant improvement in vertical jump height and lower limb strength in comparison to pre-intervention status (p < 0.05). However, the increase of 1RM leg press strength was greater in the Group A (BFRT) (41.91 ± 19.78 to 54.25 ± 22.06) than that in the Group B(PRE) group (44.85 ± 22.9 to 45.45 ± 24.70).Conclusion: The findings clearly demonstrate that Group A (Blood flow restriction training group) showed significant improvements in both lower limb strength (+12.34 kg) and vertical jump height (+5.45 cm) compared to Group B (Progressive Resistance Exercise). There was increase in strength and vertical jump in Group A (Blood flow restriction training group) that indicate its training program was significantly more effective.
