VfL Bochum says it has banned supporters from “collective, rhythmic jumping or hopping” in a section of its Ruhrstadion East Stand. The club took the step to address concerns that synchronized movement during matches can make some spectators feel unwell.

Bochum says engineers examined the stadium structure as part of upgrade work and cleared it for load-carrying capacity. However, the engineering review also points to a “trampoline effect” created by coordinated jumping, which can cause discomfort for people unaccustomed to the movement. Outlets report that the decision is framed as an “unavoidable” measure, with the club indicating it regrets the restriction while acting on the findings.

Overall coverage agrees on the same trigger—unison jumping—and the same venue focus—part of the East Stand—while differing mainly in emphasis, such as describing the effect as a trampoline mechanism and linking the action to the broader stadium upgrade investigation.
