Subject: Do carbonated drinks cut athletes wind?

The local high school coaches have instructed athletes to not drink any 
carbonated soft drinks because the carbonation in the drink will impare their 
ability to perform as athletes.  I don't know the basis for this claim, but I 
would understand that they asume what they are saying is that the CO2 in the 
drink would overload the body and impair O2 utilization.  I question this claim.  
Is there any evidence either way that drinking softdrinks would cut an athletes 
performance.  Thanks for your help.
