Efficacy of Blood Flow Restriction Training (BFRT) on Strike Accuracy and Handgrip Strength in Recreational Badminton Players

Background: Blood Flow Restriction Training has shown potential to enhance strength and neuromuscular performance at low external loads. However, its application to skill-based outcomes such as strike accuracy in badminton remains underexplored. Objective: To compare the effects of Blood Flow Restriction Training combined with low-resistance exercise (BFRT+LR) with low-resistance training alone (LR) on handgrip strength, strike accuracy, and upper-limb hypertrophy in recreational badminton players. Methods: A quasi-experimental two-group design was used with 40 recreational players allocated purposively to BFRT+LR or LR. Both groups completed a six-week programme (three sessions per week) involving bicep curls, wrist curls, triceps extensions, and isometric handgrip holds at 20–30 percent 1RM. The BFRT group trained with pneumatic cuffs applied at 40–80 percent limb occlusion pressure. Handgrip strength (dynamometer), strike accuracy (validated smash test), and limb girth were assessed at baseline, week 3, and week 6. Data were analysed using mixed-model ANOVA. Results: Significant improvements occurred over time in both groups. BFRT+LR produced greater gains in handgrip strength (time × group, p .001), strike accuracy (p .001), and arm girth (p =.005). Forearm girth and upper-quadrant performance improved similarly across groups, with significant time effects only. Conclusion: BFRT+LR enhances strength and accuracy more effectively than low-load training alone in recreational badminton players. Although findings support BFRT as a promising supplementary method, the quasi-experimental design and short duration warrant caution. Future research should employ randomised trials with longer follow-up.
