my argument is all forms of information the more the merrier are beneficial but to suggest that mirrors are bad or make things worse and as others have indicated they are a waste of time is plain wrong
anything if can used badly can be unsafe unnefective
but mirrors are not in that category people who use them wrong may wellbe..
Erm.
That's the point. People
can use mirrors and see their form get worse/not improve. This can be seen every day in your standard commercial gym.
All you're saying is that in an ideal scenario mirrors are a good thing, such as when you or another coach is supervising the athlete. Nobody disagreed with that.
It's pretty common for coaches to dislike the use of mirrors in certain situations for fairly obvious reasons, so I'm not sure why you are you're rejecting the idea so vehemently.
Edit: didn't see your most recent post until I'd written that.
in fact i would like to see the arguments of coaches who say there are negatives....that outweigh any positives.
If the athlete is on their own, as is very common for your average Joe Gym guy:
- distraction, as mentioned. This is particularly a problem if the athlete is learning a complex motor pattern. As I also mentioned, in some situations the athlete can learn to deal with the extra information.
- if the athlete needs to turn their head during the lift to view the mirror
- the athlete may have no idea what visual queues he is looking for, or what they mean when he sees them, or what to do about them.
- slightly reduced ability to acquire proprioceptive feedback, although this is situation and athlete dependant
