Abstract
This study examined the effects of shoes’ segmented forefoot stiffness on athletic performance and ankle and metatarsophalangeal joint kinematics and kinetics in basketball movements. Seventeen university basketball players performed running vertical jumps and 5-meter sprints at maximum effort with three basketball shoes of various forefoot plate conditions (medial plate, medial+lateral plates, and no-plate control). One-way repeated measures ANOVAs were used to examine the differences in athletic performance, joint kinematics, and joint kinetics among the three footwear conditions ( = .05). Results indicated that participants wearing medial+lateral plates shoes demonstrated 2.9% higher jump height than wearing control shoes (p = .02), but there was no significant differences between medial plate and control shoes (p > .05). Medial plate shoes produced greater maximum plantarflexion velocity than the medial+lateral plates shoes (p < .05) during sprinting. There were no significant differences in sprint time. These findings implied that inserting plates spanning both the medial and lateral aspects of the forefoot could enhance jumping, but not sprinting performances. The use of medial plate alone, though induced greater plantarflexion velocity at the metatarsophalangeal joint during sprinting, was not effective in improving jump heights or sprint times.
