Ever feel confused about what you should eat after a hard workout? Perhaps, you don’t feel hungry and are hesitant to eat anything or maybe you consume a protein shake because that’s what your buddies at the gym do. In my own experience, the post-exercise meal or snack is often neglected. However, what you eat after a workout is important because the body is ready to store energy again, repair muscle and fill up with fluid. Eating a well planned meal or snack can help your body properly recover for the next exercise session and repair damaged muscles, making you stronger over time. There are three important components of the post-exercise meal or snack that I would like to highlight: protein, carbohydrates and fluid. Because of the depth of these topics, I’m going to split up this blog into different posts. This blog provides recommendations about protein. Please keep in mind the optimal composition of post-exercise meal is dependent on exercise intensity, duration and when the next training session is planned.
Protein is important to consume after a workout session because it helps build and repair muscle. Additionally, eating protein after exercise may enhance and accelerate glycogen repletion (stay tuned for more on glycogen in the next blog). Proteins are made up of different sequences of amino acids. There are 20 different amino acids. Nine of these amino acids are essential and must be consumed in the diet through food. The body can synthesize the remaining 11 amino acids. The biological value of a protein containing food indicates the proportion of essential amino acids it contains in proportion to the body’s requirements. Animal sources of protein tend to have higher biological value than vegetable sources since vegetable sources of protein do not usually contain all essential amino acids. For instance, eggs have a biological value of 94 while rice has a biological value of 83. By consuming high biological value proteins after exercise muscle synthesis is optimized. Fear not vegetarians and vegans! Vegetable proteins can be wisely paired together to give them high biological value. Stay tuned to future blogs for more information on this.
Aim for 10grams of essential amino acids or 0.25-0.3 grams protein/kg bodyweight within 30 minutes of completing exercise and then every 3-5 hours over multiple meals. For instance, a 70 kg athlete would need 17-21 grams of protein post workout. The table below lists the protein content of high protein foods. Protein from foods should be your first choice, however, if whole food proteins are not available, then protein supplements such as protein powders are a practical alternative. The amount of protein in protein powder typically ranges from 16-30 grams. Protein supplements provide no additional benefits over protein rich foods like meat, milk, yogurt or eggs. Additionally, protein powder and supplements may be contaminated with illegal substances and should be third-party tested.
