Pre-Workout Nutrition for Post-Workout Recovery

Most of us have heard the advice that you need to drink your post-workout shake within 30 minutes of completing the workout and eat a full meal within 2 hours of completing the workout. This is due to the muscles having an increased ability to absorb and store amino acids and glucose following most forms of physical exertion. However, is the meal you eat after your workout really the most important when it comes to maximizing the post-workout recovery window?
“It’s not when you put it in your mouth that counts. It’s when it gets to the cells.” –Tim Ferriss in The 4-Hour Body

In one of Tim Ferriss’ countless experiments in his book The 4-Hour Body, he uses a glucometer to measure the time it takes for food to cause a blood glucose spike from the time it enters his mouth. What he found is that in most cases he peaked one and a half to two and a half hours after food consumption. This means that the protein shake you drink within 30 minutes after your workout may not be delivering amino acids to your muscles until 2-3 hours after the workout! This can be well after the muscles have lost their increased ability to uptake glucose and amino acids. As far as the meal you eat within two hours after completing the workout? Perhaps it’s really not any more important after all.

Timing Post-Workout Nutrition

If you want to maximize the increased sensitivity of the muscles after a workout, you need to make sure the nutrients are readily available. In other words, the glucose and amino acids you want for recovery need to be digested and in the blood stream by the time you finish your workout. Therefore, you cannot wait until after the workout to eat a meal or drink a shake, but rather, would need to consume them before the workout.

If you feel you are not responding to workouts like you should, take a look at your pre-workout meal in order to optimize your post-workout nutrition.

Do you put as much emphasis on the macronutrients and contents of the pre-workout meal as you do the post-workout meal? Why or why not?
