Bochum have moved to stop coordinated jumping in the East Stand after an engineering assessment identified strong vibrations caused by certain crowd movements.
The German club, currently ninth in the 2. Bundesliga, said the restriction will take effect on 11 October. Supporters in the stand will no longer be permitted to take part in collective, synchronised and rhythmic jumping or movement.
Engineering concerns behind the decision
A specialist office commissioned by Bochum found that some supporter activity creates significant vibrations inside the stand. The club said this could cause discomfort, particularly among spectators who are less accustomed to the stadium environment.
The measure has been introduced to prevent possible health issues without closing the East Stand, which has capacity for up to 10,000 people. Renovation work on the section is planned by 2028.
Goal celebrations remain permitted
Bochum made clear that spontaneous celebrations after goals are not included in the ban. The restriction is aimed specifically at sustained, organised bouncing often associated with large-scale chanting and support.
However, the club warned that failure to comply could leave it with no option but to close the stand because of the so-called “trampoline effect” created by mass jumping.
