Norwich City have painted the away dressing room at Carrow Road pink in an attempt to reduce testosterone levels in visiting teams.
Norwich City have adopted a tactic widely used in American Football to give themselves an advantage.
Some studies suggest that a deep pink colour not only lowers testosterone but also reduces levels of aggression.
“Pink has an effect, not because it is pink, but because it’s linked to childhood experiences,” Dr Alexander Latinjak, a lecturer in sports psychology at the University of Suffolk, told BBC Sport.
“If it is true that pink lowers testosterone levels then the coach should know exactly how to use that advantage tactically.”
“Now that teams will know about the pink locker room, they could take countermeasures to ensure higher testosterone levels.
“It might even be that players from other teams have some fun – they could go in there all tense but start smiling, and smiling is linked to an improvement in performance.”
The new colour scheme has so far failed to have the desired effect, though, as Daniel Farke’s side lost their first home game of the season in a seven-goal thriller with West Brom.
