Which Meals Are Recommended Post-Workout? Importance of Eating After Exercise

The process of bodily regeneration subsequent to physical exertion typically lasts around two days. Research indicates that ingesting a balanced diet within two hours following the cessation of exercise significantly expedites this process. The meal should cater to the individual necessities of the athlete, depending on the type and intensity of the workout, as well as personal bodily attributes such as health status, training level, weight, fat and muscle tissue content, and lifestyle, along with the daily meal plan.

Carbohydrates are the primary source of energy for working muscles. In the small intestine, they are broken down into glucose and absorbed into the bloodstream. The body stores glucose as liver or muscle glycogen, with liver glycogen serving as the main energy source when blood glucose levels drop, and muscle glycogen being reserved exclusively for muscle work. During intense physical activity, the body uses these reserves, but after exercise, they must be replenished. The fastest glycogen replenishment occurs immediately after training, so it is recommended to consume carbohydrates within 30 minutes after exercise. The faster the food is consumed, the faster the regeneration processes begin. However, it should be noted that the fast intake of carbohydrates after exercise is only important for people who train within 24 hours. In the case of longer breaks between training sessions, carbohydrate intake is not as crucial. In the case of daily training with high intensity, it is recommended to choose carbohydrates with a high glycemic index, as they are quickly released into the bloodstream. Products with a high glycemic index include dried fruits, bananas, grapes, 100% fruit juice, sweet potatoes, potatoes, carrots, pumpkin, white bread, white rice, and rusks. In the case of training sessions with low or medium intensity, conducted every few days, it is better to choose carbohydrates with a low glycemic index, such as whole-grain products and non-starchy vegetables. The amount of carbohydrates that should be consumed after exercise depends on the intensity of the training. The higher the intensity of the training, the more carbohydrates should be provided after exercise. The highest rate of glycogen replenishment is observed when carbohydrates are provided at a rate of 1.0-1.85 g/kg body weight per hour. The presence of carbohydrates is important not only immediately after exercise but also in subsequent meals throughout the day.

Protein constitutes the fundamental building block of the body. Each intense workout is associated with its breakdown. This process continues for some time after the completion of the exertion. Providing protein in a post-workout meal ensures that this process is halted and muscle tissue is maintained at a constant level. Protein is broken down into its components, amino acids, in the digestive tract, which are absorbed into the bloodstream and used to synthesize intracellular protein. The regulation of muscle protein synthesis (MPS) maintains and increases muscle tissue. This process is sustained by proteins absorbed from food. This process is short-lived and lasts for about 4-5 hours after a meal. Physical activity prolongs the protein synthesis process and increases its intensity. The recommended amount of high-quality protein for athletes ranges from 1,2 to 2,0 g per kilogram of body weight. Protein should be evenly distributed across the day's meals. It is recommended to consume 20-25 g of protein in each meal. The greatest influence on the regulation of MPS after exertion is leucine. Leucine is an essential exogenous amino acid. Among athletes, the phenomenon of the so-called leucine threshold is known. In order to have an impact on MPS, the protein from food must contain an adequate amount of leucine. The amount of this compound partner required to reach the leucine threshold depends on individual factors such as age or level of physical activity.

Contemporary culture encourages thinness. Women especially often participate in this trend. Additional physical activity accelerates weight loss, but it is also important to consider a suitable, balanced diet. During weight reduction, one should use a reduction diet characterized by reduced calorie intake. Although physical activity speeds up fat reduction, one should not skip a meal after exercise. As previously mentioned, a post-exercise meal inhibits the breakdown of muscle tissue. As muscle mass increases, so does the body's energy demand. Muscles require energy for daily tasks. Additionally, a larger muscle mass influences the shape of the figure.

Advised meals after workout: – whole grain granola with Greek yogurt, – basmati rice with roasted lean fish, e.g. cod, – steamed chicken with starchy vegetables, – pasta with turkey and vegetables, – full grain tortilla with vegetables and chicken, – yogurt-based or milk cocktail with fruits.

Post-physical exertion, it is recommended to consume a meal comprising protein and carbohydrates within 120 minutes to expedite the body's regeneration process, maintain muscle mass, and support muscle protein synthesis. The same applies to situations where the aim is to reduce body mass, where a faster metabolism and quicker utilisation of macronutrients by the body aid in restoring lost energy reserves during exercise more rapidly. However, it is important to emphasize that a comprehensive approach, where a properly balanced diet and regular exercise constitute necessary foundations, is required to achieve success.
