ADELAIDE has severed ties with Collective Mind in the wake of the controversial pre-season camp on the Gold Coast.

Reports emerged in March that some senior players were distressed after going through intensive emotional and mental training at the pre-season camp.

"In the last 24 hours, we've mutually agreed to part ways," Crows head of football Brett Burton told reporters on Saturday.

"We set out in this relationship two years ago and we had some really good results last year.

"Clearly, we had some good impact with the program, but this year, it hasn't gone the way we wanted it too, that's from both parties.

"We've had some good stuff out of it, but when you come to a mid-season review and you reflect on what's going well, what's not, we're not comfortable where that program is at, at the moment.

"We're going to change tact and go on a different path."

The Crows signed with mind training company Collective Mind last year on a two-year deal.

The players and Pyke famously stood in a 'power stance' during last year's finals series, including their 48-point Grand Final loss to Richmond.

However, there have been divides in the playing group since the pre-season camp and the Crows have lost their past four games to sit at 6-7 after 13 games.

Crows coach Don Pyke labelled the camp as a "fail".

"We did some really positive work in the mental performance space and the players were really engaged as we saw last year," Pyke said.

"This year, we moved that to the next phase and it's fair to say, some of those sessions didn't hit the mark and didn't resonate with the players.

"Overall, the feeling coming out from the playing group and the coaching and the people who are involved in those sessions, felt like we weren't moving the program forward.

"Therefore, we make the decision it's not in the best interest of our program."

Several players, including captain Taylor Walker, have publicly stated they enjoyed the camp, while others expressed their concerns.

"If you look at all the reasons why we've decided to terminate it, that (dividing the playing group) is not a major reason, but it is a concern from a program viewpoint," Pyke said.

"We want to make sure programs we're running inside our club have complete buy-in from everyone.

"There were enough concerns in this space to take the action we took."

Pyke and Burton confirmed as part of the camp, players were blindfolded on a short bus trip and were forced to listen to the Richmond theme song.

There was also an issue with one of the Crows' indigenous players being concerned with a talking stick that was used on the camp during a Welcome to Country.

"That had a connection to one of our players and his cultural background," Burton said.

"When we got back from the camp, that was raised and we sought clarity and he went back to his cultural background and seen if that had been passed on the right way.

"Within 72 hours from coming back to the camp, that was dealt with, and there were no lingering issues with the indigenous guys around that."

Collective Mind creator Amon Woulfe said the camp was a key factor in the decision to part ways and wished the club all the best.

"While there have been many positives in 2018, we acknowledge and have acted upon some concerns around the pre-season camp. However the ongoing focus on this has been distracting for the club and the players, and was a key factor in this decision for us," Woulfe said.

"To allow the players and the club as a whole to move on, we won’t be making any further comment. We’re very proud to have worked with this fantastic club and we wish them all the best."
