Glycemic Index Help

Can exceeding your target heart rate during aorobics have a detrimental effect on muscle gain and fat loss?

I've heard that significantly exceeding your target heart rate during aerobic activities can have a detrimental effect (possibly stripping you of muscle and or retaining more fat) I am currently weight training four times per week (one day on one day off ie, mon,wed,fri,sun) in the afternoon/eve and doing 30 minutes of cardio at my target heart rate for my age and weight five to six mornings a week in addition to following a six meal a day "glycemic index" type diet in an effort to gain/retain muscle while losing fat and generally increase my cardiovascular health.

1. Exceeding your THR (target heart rate) in short bursts is actually probably not only safe, but good for you. IF you don't push a little every now and then, how can you expect to get better? I am not saying, however, to train above your THR. Just don't worry about going a little higher every now and then. Also remember to reevaluate your THR about every month or so based on your RHR (resting heart rate)
2. Overburdening of any organ cud be detrimental to it.
