Pre-Training Nutrition Essay

Decent Essays

Not only can pre-training nutrition optimize training to maximize output, but without proper nutrition post-training benefits will not be seen, as it is essential the body is properly fueled to supply the metabolic processes for recovery, growth, and preparation for the next session. In this section, post-training nutrition will use carbohydrates, omega-3 fat source, protein, and creatine to maximize metabolic adaptations to overcome the metabolic stresses from training with the goal of overcoming both bone and muscle breakdown for increased synthesis, and preparing the bodies energy stores for the next bout.
Carbohydrates

Timing: immediately after within 2 hours of last set
Strategy: high glycemic …show more content…

Muscle glycogen storage is an essential source utilized during resistance training, as the glycogen stored can be readily metabolized and used for ATP production in the cytosol and mitochondria, where the stored glycogen can provide ATP three times as rapid due to the proximity to the site of contractions within the muscle cells (Candow, 2017b). During muscle contractions, like ones produced during resistance training, muscle glycogen stores are utilized first as the primary source of glycolysis for ATP production, but as stores deplete the liver is able to metabolize glycogen through a process of glycogenosis to help maintain blood glucose levels and can be utilized by the muscle. During repeated contractions and movement during resistance training, the muscle is able to absorb the glucose into the muscle cell rapidly due to the specialized transport proteins, GLUT-4, where increased contractions and movement results in increased recruitment of the proteins (Candow, 2017b). In order for muscles to be able to metabolize ATP utilizing muscle glycogen during exercise it is essential muscle glycogen stores are filled post exercise in order to sustain high performance and duration of the next performance. Without proper replenishment, specifically the muscle glycogen stores, post exercise, the output of hepatic glucose decreases at every level of intensity, negatively effecting both intensity and duration sustainability over
