Bochum bans collective fan jumping in East Stand over vibration concerns

German second-division club VfL Bochum has barred synchronized fan jumping in the East Stand of its Ruhrstadion, citing vibration findings from a technical inspection.

• VfL Bochum banned collective, synchronized jumping by fans in the East Stand, in effect from Sunday's match against Arminia Bielefeld.
• An engineering inspection found fan movements cause strong vibrations, the "trampoline effect," though the club said the stand remains safe at full capacity.
• Bochum said the ban, issued via an administrative order from the city's building supervisory authority, excludes spontaneous actions such as goal celebrations.
• The club warned non-compliance could bring immediate consequences, including full closure of the stand and the loss of around 10,000 spectators.
