Impact Of Force Dampening Basketball Floors On Propulsive Kinetics During A Countermovement Jump

Jumping is a necessary skill in basketball performance. Many customized basketball floors are designed to reduce impact reaction forces when landing from a jump in training and competition. However, the impact of force-dampening basketball floors on jumping performance remains undocumented. PURPOSE: We aimed to assess the impact of force-dampening basketball floors on countermovement jump height, propulsive impulse, and instantaneous take-off velocity. METHODS: Nineteen recreationally active participants (mean ± SD: age = 25.7 ± 5.8 y; height = 171.8 ± 9.8 cm; weight = 73.4 ± 13.6 kg) performed five maximal barefoot countermovement jumps on four custom-made basketball floor samples of varying force dampening capabilities, each customized and fitted to a force platform. The countermovement jump with the highest peak vertical ground reaction force on each floor during landing was used for analysis. Repeated measures ANOVAs were used to evaluate differences in countermovement jump height, propulsive impulse, instantaneous take-off velocity, and propulsive peak force at take-off between the four floors. RESULTS: There was a significant difference in maximal countermovement jump height between the floors (p < 0.001; Floor A = 17.49 ± 6.09 cm < Floor B = 26.20 ± 6.7 cm < Floor D = 32.03 ± 10.02 cm = Floor C = 32.87 ± 8.87 cm). There were no differences in propulsive impulse (p = 0.91), take-off velocity (p = 0.90), or peak propulsive force (p = 0.56) between the floors. CONCLUSION: Basketball floor construction exerted a significant impact on maximal countermovement jump height. These findings suggest that floor construction may play a decisive role in influencing basketball performance, emphasizing the importance of understanding the utility of force-dampening flooring in training and competition.
