Here's a little article that explains how to minimize muscle loss during the "90-minute window" after a workout. I cut out the last half due to the length and uneccessary information. If you would like to read this article (or part 2, the solution), I put a link to both articles at the bottom.

The Unlikely Scientist

John M Berardi is an exercise and nutritional biochemist at the University of Western Ontario. He can be reached at [email protected].
When I first began pushing iron, I knew very little about the science of weight training and nutrition. And to be honest, I really didn't care much about the science part. You see, I was 18 years old. At that age, all I personally cared about was being big, strong, and intimidating. Oh, and I'd better not forget to mention that I also cared a lot about sex. Somehow I figured that the pursuit of raw, intimidating "manliness" would ultimately equate to getting chicks. So most of my mental reserves were directed at getting really big and kicking everyone's ass both in and out of the gym.
Since my brain was pretty much occupied with all those deep philosophical musings, you can probably imagine that there wasn't much room in my melon for scientific thought. That was compounded with the fact that my predominant science experiences had been with Mr. Richard Wack, the very nerdy, defeated high-school chemistry teacher that had us mixing oil and water to illustrate chemical bonding or lack thereof (I swear that was his name!).
At the time, as ignorant as I was to science, there were a few scientifically validated nuggets of wisdom floating around the local gym. Sure, if I'd have known they were "science," I probably would have ignored them entirely. But since these pieces of science were cleverly disguised and because all the big guys were talking about them, I tried to use this information to it's fullest.
We discussed the merits of statements like "eating a lot of extra protein will make you grow" and "sleeping 8 hours a night will help you recover." These statements seemed to be entirely true and backed up by countless gym experiences. Today, they also happen to be backed up by well-controlled, university studies.
One statement that I was always quite fond of was the one that told me that there was a 90-minute "window of opportunity" after training in which I could eat tons of protein and carbohydrates. Since I love eating protein and carbs, I loved that particular gym "fact." And not only was it cool that it allowed me to pig out on protein and carbs after my workouts, it was equally exciting that in doing so, I would be recovering from my workout and packing on muscle mass at an alarming rate. "Who needs science?" I'd ask, "I'm gonna go eat!"
Unfortunately, somewhere along the way, this crucial piece of post-workout wisdom has been lost. As a result, few modern trainees have even heard of the "window of opportunity" concept. Some guys today just think that eating "a little something" is enough. To go even further, some even have the audacity to fast for hours after workouts in order to "burn more fat" or to "enhance their GH response." It frightens me that these new practices are almost becoming as popular as the old window I was so fond of taking full advantage of. But I'm here to do something about it!
Despite the anti-science beginnings I discussed earlier, you may be amazed to know my current profession involves scientific research. In fact, I sit here typing this article surrounded by nothing other than science textbooks and journals. It constitutes some of the literature that I've read along the way to a PhD program in exercise and nutritional biochemistry. Who would of thunk it? Armed with all this science, my plan is to unscramble the post-workout puzzle that has lead so many trainees astray.
Post-Workout 101
Over the last few years, I've spent quite a bit of time trying to unscramble the post-workout puzzle in my own mind. And as a result of my research, I've discovered that immediately after a single bout of exercise, three main physiological events must be manipulated for enhanced recovery. These changes can only be described as "destructive" in terms of both training performance and muscle protein balance.
Before I go on, I want you to keep in mind that by exercise I mean either strength and power training or endurance training. Unfortunately, no trainee is immune to the three post-exercise phenomena. These three factors are as follows:
1. Glycogen Stores are low
2. Protein Breakdown is increased
3. Muscle Protein Balance is negative
It should be noted here that in addition to the above that Protein Synthesis also goes down after an endurance training session. And Protein Synthesis either goes up or remains unchanged after a strength training session. But either way, Protein Breakdown still predominates.
For those not well versed in physiological jargon, here's a little explanation of each:
Glycogen is muscle energy. Low glycogen stores mean that there's less cellular energy for daily life and certainly less energy for subsequent workouts. In this situation, training and performance suffer.
Protein Breakdown indicates that body tissues (which are made of protein) are being degraded. Increases in protein breakdown can lead to losses of muscle mass.
Muscle Protein Balance is regulated by the balance between Protein Synthesis and Protein Breakdown in the following way:
Muscle Protein Balance = Protein Synthesis - Protein Breakdown
Immediately after an endurance workout, protein synthesis (building) goes down and protein breakdown goes up. This leads to a negative Muscle Protein Balance and a loss of muscle.
And immediately after a strength workout, protein building either stays the same or slightly goes up but protein breakdown goes way up. This also leads to a negative Muscle Protein Balance and a loss of muscle.
As a result of these three post workout phenomena, a failure to rapidly bring the body back into recovery mode (i.e., to increase glycogen stores, to increase protein synthesis, and to prevent protein breakdown), has severeal potential consequences:
1. Prolonged muscle soreness and fatigue.
2. Poor subsequent performances on the track, field, and/or in the gym.
3. Symptoms of and or full-flegged staleness and overtraining.
4. Minimal gains in muscle mass despite a well-designed training program.
5. Losses of muscle mass and a secondary lowering of metabolic rate can occur if volume and intensity get high enough
---------------------------------------------------------------------------
So basically what this article is saying, is to minimize muscle loss during post-workout, you need to;
1. Rapidly replenish the low glycogen stores in your muscles
2. Rapidly decrease the muscle protein breakdown that occurs with exercise
3. Rapidly force further increases in muscle protein synthesis in weight trainers and/or restore muscle-protein synthesis in endurance athletes
