Following repeated trampoline jumping, the actual vertical jump height on the ground decreases compared to before the trampoline session, and the perceived jump height feels even lower than the actual height.
This study investigated the time course of the readaptation of motor and perceptual functions following trampoline jumps, focusing on how these aftereffects diminish over time.
Fourteen male participants performed vertical jumps on the ground before and after completing 30 repetitive trampoline jumps at 1.2 Hz.
In the 0-minute condition, the actual vertical jump height was lower than in the pre-trampoline jump, and participants underestimated their jump height relative to their actual performance.
These findings indicate that the passage of time is sufficient for motor recovery, whereas perceptual recovery requires a longer duration, suggesting that motor and perceptual aftereffects of trampoline jumps follow distinct temporal dynamics in their dissipation.
Following repeated trampoline jumping, the actual vertical jump height on the ground decreases compared to before the trampoline session, and the perceived jump height feels even lower than the actual height. While it is known that these aftereffects dissipate with subsequent vertical jumps, the time required for their dissipation when no additional jumps are performed remains unclear. This study investigated the time course of the readaptation of motor and perceptual functions following trampoline jumps, focusing on how these aftereffects diminish over time. Fourteen male participants performed vertical jumps on the ground before and after completing 30 repetitive trampoline jumps at 1.2 Hz. To assess the time-dependent recovery process, the first post-trampoline vertical jump was conducted under five conditions: immediately (0 min) and at 1, 2, 3, and 4 min after trampoline jumps. After each post-trampoline vertical jump, participants estimated their jump height and reported their perceived performance. In the 0-minute condition, the actual vertical jump height was lower than in the pre-trampoline jump, and participants underestimated their jump height relative to their actual performance. While the actual vertical jump height recovered to its original level within 1 min, the perceived jump height remained lower than the actual height at this time point. The ability to accurately perceive jump height took 2 min to recover. These findings indicate that the passage of time is sufficient for motor recovery, whereas perceptual recovery requires a longer duration, suggesting that motor and perceptual aftereffects of trampoline jumps follow distinct temporal dynamics in their dissipation.
