Foods to Eat After Cardiovascular Exercise
The foods you eat after exercise should help to promote recovery. Foods do not necessarily need to have higher levels of protein to rebuild damaged tissues, but carbohydrates are essential to replenish energy.
Although protein is desirable to assist in the rebuilding process of muscle tissue, too much can slow digestion and, in turn, delay recovery. Sports drinks and foods that are designed with recovery in mind tend to contain less protein, fats, and fiber. Often, the simpler food will be better absorbed by the body.
Why Don’t I Need More Protein?
Think about a car with just an engine. Sure, the engine will run, but the car won’t make it too far without a transmission, drive train, and so on. Likewise, the body needs more than just protein for recovery; protein is just one ingredient. While protein is recognized as the body’s tissue builder, the body also needs iron to have red blood cells carry adequate oxygen to tissues, phosphorus for energy transfer and storage, as well as many other micro- and macronutrients.
Protein is a very important food to consume while on an exercise regiment; however, most foods that we eat on a regular basis (post-exercise or not) contain sufficient protein. The key to promoting optimal recovery is to eat a heavier concentration of carbohydrates along with a good balance of nutrients.
What Foods Have the Best Balance?
Many research studies indicate that adequate amounts of carbohydrates are essential for proper recover. Muscle protein may have also been damaged during strenuous exercise regiments, so protein consumption may also be necessary. Although, how much protein is enough to aid in recovery, but not too much to hinder it? How much protein in excess would slow the digestive system from breaking down the food? Current research suggests that every 4 grams of carbohydrate should be consumed with 1 gram of protein.
Also characteristic to pre-exercise food, the post-exercise food should not be too heavy, but should provide enough energy to support recovery. Many foods from the fruits and breads food groups can satisfy this criteria, some examples are listed below.
How Many Carbohydrates Should I Consume?
Immediately after exercise, the body’s most important task is to re-fuel. Between 75 and 100 grams of carbohydrate will supply adequate energy until a larger amount of carbohydrate can be consumed later. See below for a reference of foods with 75 to 100 grams of carbohydrates.
When Is The Best Time To Eat After Exercise?
Eating within 45 minutes after exercise seems to be the most widely agreed upon timeframe from most research professionals. Protein synthesis can remain as high as 80% post-exercise for about 4 hours and will slowly fall back to zero after 24 hours. However, most Americans take in adequate protein to meet this need. As stated before, the key is to consume a larger amount of carbohydrates to aid in the proper uptake of protein.
For those who take more convincing, start with simple foods that are high in carbohydrates without sacrificing protein. Two cups of low fat chocolate milk is a great way to knock out about 50 grams of carbohydrates and 16 grams of protein. A few other examples are listed below.
Appropriate High-Carbohydrate Foods — Post-Exercise
Greater than 75–100g Carbohydrate
Sports drink, more than 40 ounces
1 banana and 3 slices toast with jam
3 pancakes with syrup
Greater than 75–100g Carbohydrate + Protein
1 or 2 sport energy bars
2 cups fresh fruit and 1 cup yogurt
Half a medium-size
pizza (about 4 Slices)
The Mechanism for Protein Uptake
As the body recognizes higher concentrations of glucose in the blood stream, a signal is sent to the pancreas to release insulin. In a healthy body, the insulin binds the glucose and stores it into muscle cells. This uptake of glucose into the cell is stored as glycogen and is facilitated by the action of proteins.
