Right so as I'm a fitness coach and part time football coach I have spoken to 6 coach colleagues.
5 Male, 1 Female. Two were/are international players in Rugby and hockey.
Not one of them think wearing a suit would make any difference to team bonding or team success. Everyone said they prefer wearing the sports coaching track suits because they are more comfortable and represent the same thing a suit would do.
As I have done some strength and conditioning with some of the students this evening I asked another 6 people the same question. 4 girls and two boys aged 17/18.
All of them want to be a sports professional of some sort. Hockey is massive here, as is cricket.
Only one said they would want to wear a suit. I asked him why, and it was purely for a vanity reason. Nothing to do with team bonding, winning mentality. Just pure ego.
The others again said they prefer the training gear or actual kit as they are more comfortable and are designed for what they are training for.
As I said "a load of bollocks ", mate.
