Cycling abilities and amino acid functions

Cycling races can last for several hours. During long rides, it is essential to replenish energy before you run out of energy. In particular, during races that last several days, it is extremely important to take in nutrients that will help muscle recovery and provide endurance.
Here we will explain the abilities and nutrients required for cycling competitions, and introduce the functions of the amino acids that support them.
Recovers tired muscles after long rides
In cycling, the strength of the lower body, such as the quadriceps and hamstrings, is important. These muscles are classified as some of the largest muscles in the body, but if they are damaged during long periods of riding, their strength will decrease. In order to prevent muscle loss, it is important to recover from damage as quickly as possible. To do this, it is necessary to take in protein and amino acids.
In particular, essential amino acids that contain a lot of leucine are effective in muscle recovery.
Post-training nutrition strategies to efficiently improve running performance
To increase speed in a sprint, you need to increase the strength and muscle mass of your legs. Strength training is essential for this purpose. For hill climbing, you also need to train the strength of your arms to pull the handlebars. Proper care is required after training. Along with rest, adequate nutrition, mainly protein, is essential. Not only the timing and amount of your drink, but also the contents of your drink are important.
It is important to take in "leucine," which acts as a signal for muscle synthesis, and "essential amino acids," which are the building blocks of muscle, along with protein in order to build an efficient body.
Supports mitochondria to use lipids as an energy source
Cycling, where endurance is important, requires a lot of energy. The main sources of energy are carbohydrates and lipids. During strenuous exercise that makes you out of breath, carbohydrates are mainly used, but the amount of carbohydrate energy stored in the body is insufficient. For this reason, it is important to also use lipids as an energy source.
In order to use lipids as energy, the mitochondria inside the cells are important. One of the amino acids, cystine, protects mitochondria from oxidative stress, thereby enhancing mitochondrial function.
Strategic carbohydrate intake is key during long cycling events!
Carbohydrates are an important nutrient as an energy source, but the amount is limited, so if you engage in long, hard exercise like cycling, you will run out of carbohydrates in your body and experience a "hunger knock." Cycling requires 1 kcal per hour, so you need to actively take in carbohydrates (if a person weighing 500 kg rides for 60 hour at 20 km/h).
The amino acids "alanine" and "proline" help the body efficiently store carbohydrate energy, helping to maintain endurance.

Summary
| Required skills for cyclists | Functions of Amino Acids |
|---|---|
| Recovery of muscles that have been severely damaged by running long distances. | The essential amino acid "leucine" is rich in this ingredient, which helps speed up muscle recovery. |
| Strength training is essential for increasing leg muscle mass and strength. It is important to take in sufficient nutrition and rest after training. | "Leucine", "essential amino acids", and proteins enable efficient muscle synthesis. |
| Endurance to run long distances. It is necessary to make effective use of lipids to cover the small amount of carbohydrates. | "Cystine" helps utilize lipids for energy. |
| The key to running long distances is to avoid running out of stamina and becoming fatigued as much as possible. It is important to keep your blood sugar levels up. | "Alanine" and "proline" help the body efficiently store carbohydrate energy and are useful for maintaining endurance. |
