The purpose of this study was to examine the immediate effect of a medicine ball downward slam exercise on the jump smash shuttle speed of badminton players. The study aimed to determine whether performing the slam exercise before executing a jump smash could acutely enhance smash velocity through a post-activation potentiation effect. A total of 20 male badminton players from Lakshmibai National Institute of Physical Education, Gwalior, were randomly divided into two groups: an experimental group that performed the medicine ball downward slam exercise before executing the jump smash, and a control group that performed the jump smash without any prior activity. The jump smash shuttle speed was measured using a radar gun immediately after the intervention. Data analysis was performed using Jamovi statistical software (version 2.6.13). The Shapiro–Wilk test (W = 0.931, p = 0.162) confirmed normality of data distribution. Analysis of Covariance (ANCOVA) was applied to compare post-test mean differences between groups while adjusting for pre-test scores. The ANCOVA results revealed a significant main effect of the medicine ball downward slam on jump smash shuttle speed, F (1,17) = 81.8, p = 0.001. The adjusted post-test means were higher for the experimental group (147) compared to the control group (130), indicating a meaningful improvement in smash velocity following the immediate slam activity. Post hoc comparisons (Tukey) further confirmed a significant difference between the two groups (mean difference = 16.8, p = 0.001). The findings suggest that performing medicine ball downward slams immediately before executing a jump smash can acutely enhance shuttle speed in badminton players. This improvement may be attributed to post-activation potentiation mechanisms that temporarily increase neuromuscular efficiency. Coaches and trainers may incorporate medicine ball slams as part of dynamic warm-up protocols to optimize power output during competitive play.
