The VfL Bochum football club has implemented a mandatory ban on organized, rhythmic jumping and bouncing in the Ostkurve (East Stand) of the Vonovia Ruhrstadion. The directive, issued by local building authorities, prohibits synchronized jumping movements by fans, though the club clarified that spontaneous reactions like goal celebrations are not included in the restriction. This measure is effective immediately, beginning with the club’s upcoming 2. Bundesliga home match against Arminia Bielefeld.
Building Authorities Cite Unwohlsein-Effekt
The decision stems from a technical assessment conducted during ongoing renovation work at the stadium. According to a statement from the club, experts identified that synchronized, rhythmic movements by large crowds can trigger a “Trampoline effect.” This phenomenon, the club reported, may lead to an “Unwohlsein-Effekt”—or a feeling of discomfort—among spectators in that section of the stadium. While the restriction limits fan movement, the club emphasized that the measure is not a result of structural instability or a lack of load-bearing capacity in the standing area.
Risk of Full Stand Closure
The prohibition is enforced through an official regulatory order from the local building supervisory authority. VfL Bochum is now tasked with both implementing the ban and monitoring compliance during match days. The club warned that failure to adhere to these rules could result in severe consequences, including the potential complete closure of the East Stand, which accommodates up to 10,000 spectators.
Precedent in German Football
FC Magdeburg. In 2016, authorities at the MDCC-Arena restricted rhythmic jumping in the North Stand due to concerns regarding strong vibrations and potential damage to the steel-reinforced concrete structure. That restriction remained in place until 2019, when structural reinforcements were completed, allowing the ban to be lifted. The restriction in Bochum is currently expected to remain in effect until the conclusion of the stadium’s broader renovation project, which is scheduled for 2028.

Match Day Logistics
The ban applies to the club’s home fixture against Arminia Bielefeld, which is scheduled for Sunday at 1:30 p.m. local time (12:30 p.m. UTC). While the club has explicitly stated that the prohibition does not apply to celebrations following a goal, the restriction targets choreographed jumping routines commonly performed by supporter groups. Fans attending the match at the Ruhrstadion are expected to follow these new protocols to ensure the continued operation of the East Stand.
