Recovery from all the effort

Ever wondered why elite riders sem to mention smoothies after races, alot these days. Heres some info by Joe Friel excerpted from The Paleo Diet for Athletes by Joe Friel and Dr. Loren Cordain, due out this Autumn 2004.
 
During exercise, body fluids shift increasingly toward an acidic state. There is also considerable evidence indicating that as we age, our blood and other body fluids become increasingly acidic. This natural tendency toward a reduced pH with aging when combined with exercise creates a cumulative effect resulting in a disturbingly lowered pH (increased acidity). But regardless of age, if this acidic state following exercise is allowed to persist for some period of time the risk of nitrogen and calcium loss is greatly increased. The reason for this is that the body attempts to reduce the acidity by releasing minerals into the blood and other body fluids that have a net alkaline-enhancing (acid-reducing) effect thus counteracting the increased acidity. Calcium from the bones and nitrogen from the muscles meet this need.
 
The problem is that in neutralizing the acid this way we give up valuable structural resources. You're essentially peeing off bone and muscle as the acidity of your blood stays high. While cannibalizing tissue in this way is necessary from a strictly biological perspective, this is an "expensive" way to solve the problem from an athletic perspective. For while body fluids may be chemically balanced in this process, future performance and even health may well be jeopardized as muscle and bone are compromised.
 
Research has shown that fruits and vegetables are the only foods that have a net alkaline-enhancing effect (Remer, T. and F. Manz. "Potential renal acid load of foods and its influence on urine pH." J Am Diet Assoc 95: 791-7). So by using fruits and juices, which have a net alkaline-enhancing effect (reduced acidity) in your recovery drink you are doing more than merely replacing carbohydrate stores; you're also potentially sparing bone and muscle.
 
Homebrew Recipes Based on all of the above then, what you would like to have in a homemade recovery drink are fruits and juices to provide fluids and slow-releasing carbohydrate with electrolytes while reducing blood acidity, added glucose as a quickly absorbed source of energy, protein to replace what was used in exercise and to prevent further muscle breakdown during recovery, and added sodium since fruits and juices are low in this electrolyte. You can make such a "smoothie" drink in your blender from food sources available in your kitchen. Start by putting about 12 to 24 ounces of fruit juice in a blender according to your body weight as shown in the table below. Apple, grape, grapefruit, orange and pineapple are good choices due to their relatively high glycemic loads (glycemic index multiplied by carbohydrate content) and electrolyte makeup. To this add a fruit and glucose (also called "dextrose") according to the table. (Glucose may be purchased online at BulkFoods.com, MandevilleCompany.com, Sausage-Stuffer.com, SpokaneSpice.com and SportQuestDirect.com.) Then, with the blender still running, add protein powder from either egg or whey sources. Sprinkle in two or three pinches of table salt. To chill it, add a handful of ice if you didn't use frozen berries in the recipe. There you have it-a fairly inexpensive drink that has all of the ingredients needed for immediate recovery. Recipes for "homebrew" recovery drink by body weight. Each recipe also includes one fruit source and two to three pinches of table salt.

You don't need to use such a recovery drink after every workout; only after those that include a significant amount of high intensity or those that are 60 to 90 minutes or longer. The more fit you are the longer the workout, which triggers the need for such a recovery drink. After short and low intensity workouts you can make the homebrew drink without the glucose. Be careful using this recovery drink when you don't need it as the high glycemic load is likely to add unwanted pounds of body fat.
 
Seems some BP garages now serve up freshly made smoothies, so you could grab a recovery tonic on your way home from an event and try it for yourself.
