During training, we are in a catabolic state, making the post-training period the most crucial moment... Within 45 minutes of ending physical exertion, the body shifts into a new phase.
Supplements following exercise – BCAA constituents
BCAA comprises the most widely recognized and effective trio of amino acids – leucine, isoleucine, and valine. These amino acids form the basis of protein cells, and without them, muscle tissue development is impossible. Furthermore, they are classified as essential amino acids, meaning the body cannot synthesize them, and they must be acquired through diet or supplementation. Inadequate intake or improper nutrition of these amino acids can result in a lack of progress. Consuming BCAA post-workout ensures several positive effects: enhances the efficacy of other supplements; contributes to fat tissue reduction; stimulates muscle mass increase; protects against muscle tissue breakdown; amplifies strength indicators, etc. Practical experience indicates that ingesting BCAA post-workout or during training yields optimal results, as the beneficial compounds rapidly reach the muscles, nourishing them and aiding in tissue repair and regeneration. BCAA is also frequently utilized before commencing physical activity. In such instances, muscles are fortified with nutrients, endurance is amplified, and each cell is equipped with necessary energy. However, if we contemplate whether BCAA consumption prior to or following exercise is superior, the latter option proves more advantageous. Nonetheless, it is crucial to remember that each individual is unique, and some may benefit more from post-workout BCAA intake, while others may reap greater rewards from pre-workout or intra-workout consumption.
The protein compound
Among the most frequently utilized and popular nutritional supplements are protein supplements. They are relatively affordable, possess a rich protein composition, and can be consumed at any moment. They can be consumed throughout the day when time for meal preparation is scarce, as well as prior to and following training. Each of these options has its benefits. Upon completion of training, the body exhibits a particular demand for proteins and carbohydrates. At that juncture, a protein supplement or a gainer should be consumed, which also supplements carbohydrates. This can result in an increase in the speed of protein synthesis within muscles. Protein also aids in the enhancement of insulin production (anabolic hormone) and exerts a substantial influence on muscle tissue regeneration processes.
Carbohydrate Requirement
During strenuous physical exertions, a considerable amount of energy is consumed. As soon as the physical strain is over and within an hour after exercise, the so-called carbohydrate window opens. After the cessation of physical activity, all available carbohydrates are utilized to replenish energy reserves, i.e., to restore muscle glycogen. Therefore, it is essential to consume carbohydrates after workouts to ensure an immediate supply of glucose to the muscles. Carbohydrates with a low glycemic index are present in products such as fruits, honey, chocolate. However, they can also be supplied through supplements such as Carbo or Gainer (carbohydrate-protein mix), which also meets the protein requirement.
Creatine
Taking creatine after training is fitting as it is transported to the muscles through blood. After an intense workout, blood flow increases significantly. Additionally, after training, we must take in protein and carbohydrates, which promote better transportation of creatine to the muscle and increase its beneficial properties. Creatine: supplements ATP; contributes to muscle mass; buffers lactic acid; improves energy exchange in tissues and cells; facilitates anabolic processes. In the International Society of Sport Nutrition, the results of studies on taking creatine before and after training have been published. In the experiment, 19 people participated, who were divided into two groups. One group took 5 g of creatine before training, and the other group took the same amount after training. The men trained five times a week for a month and consumed 1.9 g of protein per kilogram of body weight. The results of the experiment showed that creatine had a positive effect on increasing strength and muscle mass in all participants, but there were differences. The people who took the supplement after training increased their level of lean muscle mass more than the people who took it before training.
