Players have since been forced to get ready for action at a football centre 100 yards away from the Glasgow Green facility.
The £5m arena was opened for the 2014 Games and was intended to be used as a hub for the national set-up thereafter.
However, it became a Covid testing site during the pandemic and only the outdoor pitches have reopened since, leaving changing rooms, first-aid facilities and a café locked away.
Scottish Hockey’s chief executive Barry Cawte said players were being treated as “second-class citizens”.
“If this was any other mainstream sport, football or rugby, this would not happen,” he said.
“We are all about inclusion and getting young girls into sport, but it is quite clear Glasgow Life do not want to operate it in the long term.”
Mr Cawte said the national side was only permitted access in 2022 after highlighting that the closure was affecting their preparations for the Games in Birmingham.
