Abstract:
The purpose of this study was to examine the effects of velocity-based resistance training (VBRT) and percentage-based resistance training (PBRT) on speed and change-of-direction ability in university badminton players. Thirty-three university-level players were divided into VBRT, PBRT, and control (CON) groups, training twice weekly for eight weeks. The VBRT group adjusted loads based on individual load-velocity profiles (LVPs). Post-intervention, both VBRT and PBRT groups showed significant improvements in the10-m sprint test, T-test for agility, hexagon jump test, and shuttle change of direction test performance (all p < 0.05), with no changes in the CON group. VBRT led to greater performance gains, with no significant difference in perceived exertion between VBRT and PBRT despite higher absolute loads for VBRT.
