1. How does protein repair and rebuild muscle?
Protein is made up of amino acids, which act like building blocks for the body. When you eat protein after an activity, it gives your muscles the amino acids necessary to repair and rebuild.
And why is this important? Well, repetitive muscle contractions from jumping, running, and other forms of exercise can break down muscle cells and cause damage to the muscles in your arms, legs, and the rest of your body.
Taking in adequate protein after exercise helps reverse damage, build muscle, and get you ready for the next tough workout
2. How much protein do you need for muscle recovery?
“Protein synthesis” is the scientific way of saying “repairing and growing muscle.” Post-exercise intake of about 0.2–0.5 grams of protein per kilogram of body weight (g/kg) has been shown to increase this muscle protein synthesis.1 That’s somewhere around 10–30 g of protein depending on your body weight, and the intensity and duration of your workout. The longer and more intense the exercise, the more protein is needed to optimize recovery. Over the course of the day, active individuals should aim to eat about 10–20 percent of their total daily energy intake from protein (or about 50–100 g, based on a 2,000-calorie diet). Athletes may need even more protein and should aim for 1.2–2 g/kg each day.1
While protein gets most of the glory when it comes to post-exercise fuel, carbohydrates have a role to play, too. In fact, carbohydrates and protein in a 3:1 or 4:1 ratio have been found to help maximize recovery by replenishing energy stores.
3. Why is it important to have protein right after a workout?
Intense or prolonged activity causes an increase in muscle protein breakdown. This is followed by an increase in muscle protein synthesis over the next 24 hours. For that reason, it’s important to consider both the amount of protein you eat and when you eat it.
Ideally, protein should be eaten within 30 minutes of finishing a workout. Combined with simple carbohydrates (i.e., sugar), your post-exercise snack can help both replenish energy stores and rebuild muscle. Miss the 30-minute window? While less effective, fueling any time after activity is still important and can be beneficial.
4. What type of protein is best after a workout?
From whole foods to supplements and animal- to plant-based proteins, there are many ways to meet your protein needs, and it can be confusing to navigate. Also known as complete proteins, high-quality proteins (those which are highly digestible and provide an adequate amount of essential amino acids, which our bodies can’t make) are most effective for building, repairing, and maintaining muscle.
High-quality food sources of protein include dairy, fish, meat, eggs, and soy. However, that’s not the only type of protein that’s useful. You’ve likely seen whey (from dairy) and plant-based protein powders, concentrates, and isolates on the market, too.
Like soy, pea protein is a plant-based protein that has been found to be effective for post-workout recovery and can be used by all athletes — even those who follow a vegan diet. Just keep in mind, pea protein is an incomplete protein, meaning it delivers fewer essential amino acids, so you may have to eat more to have the same recovery impact as whey or soy.
With that said, for most people, eating enough calories during the day and including a variety of plant-based foods in the diet can ensure adequate protein and amino acid intake. You don’t need to eat animal protein to support post-workout recovery; all types of protein can work.
5. What foods can help repair and rebuild muscle?
Whole foods are the foundation to a healthy diet, but a big, homecooked meal isn’t always convenient when on the move. Below are a few examples of nutritious, post-workout foods that can help promote recovery without slowing you down:
Quick At-Home Recipes:
