In the anime series Kenichi: The Mightiest Disciple, one of the masters, Akisame, is said to have converted all the muscle in his body into pink muscle. This concept has sparked curiosity about whether it is possible to transform one's muscle type. In reality, the human body has over 600 muscles, composed of various muscle fibres, including slow-twitch type 1 and fast-twitch type 2 fibres, with the former being red due to high oxygen content and the latter being white due to lower oxygen levels. While it is generally not feasible to convert all muscle fibres to a single type, understanding the characteristics of different muscle fibres can provide insights into training and athletic performance.

What You'll Learn
Slow-twitch (red) muscle fibres
Slow-twitch muscle fibres, also known as type 1 or red muscle fibres, are oxidative muscle fibres that use oxygen for energy production. They have a high oxygen content due to the presence of myoglobin, a red-coloured protein that binds and stores oxygen. This gives the muscle fibres their reddish appearance. Slow-twitch fibres have a rich blood supply and are well-vascularised, with numerous blood vessels and capillaries that deliver a plentiful supply of oxygen to the muscle cells. They also contain more mitochondria, which play a crucial role in energy production.
The contraction speed of slow-twitch fibres is slower compared to fast-twitch fibres, resulting in weaker contractions. They are characterised by their high endurance capacity and ability to sustain low-intensity activities for long durations without fatiguing. These fibres are essential for maintaining posture, stabilising bones and joints, and performing small, frequent movements that require endurance rather than powerful, fast movements.
Slow-twitch fibres are commonly found in muscles that need to work tirelessly to support the body, such as the muscles in the back and lower legs. They are also prevalent in long-distance runners, who can have up to 95% of slow-twitch fibres in their leg muscles. In contrast, sprinters tend to have a lower percentage of slow-twitch fibres, typically under 20%.
The distribution of slow-twitch and fast-twitch fibres in the body is influenced by genetics, and it is believed that this composition can be altered through specific training regimens. While it is possible to convert type 1 muscle fibres to type 2a, achieving a complete conversion to a single type is not feasible, especially for type 1 fibres, which are more resistant to change.

Fast-twitch (white) muscle fibres
The concept of "pink muscle" comes from the anime series "Kenichi: The Mightiest Disciple", in which one of the masters, Akisame, is said to have converted all the muscle in his body into "pink muscle". In reality, however, this is not possible.
Now, onto the topic of fast-twitch (white) muscle fibres:
Fast-twitch muscle fibres, also known as white muscle fibres, are skeletal muscles that help with power performance for short periods. They are called fast-twitch fibres because they contract and relax faster than slow-twitch fibres. These fibres are further classified into two types: Type IIa and Type IIx (formerly known as Type IIb).
Type IIa fibres, also known as intermediate muscle fibres, can be used for a longer duration as they have a longer time to fatigue. They are also used for specific types of exercises. Type IIx fibres, on the other hand, are better at providing force and are necessary for quick, unexpected movements. However, they fatigue faster, making them inefficient and earning them the nickname couch potato fibres.
Fast-twitch fibres have a lower myoglobin content, which gives them their white colour and also results in lower oxygen content. They gain energy anaerobically, without the use of oxygen, and primarily from the sugar glycogen. While glycogen provides energy quickly, it is exhausted just as fast, leading to faster fatigue in these muscle fibres.
The amount of fast-twitch fibres in an individual varies and is determined by genetics. People who excel at sprint events tend to have a higher number of fast-twitch fibres, while those good at endurance sports have more slow-twitch fibres. Training can influence these fibres, improving their endurance levels, but it cannot change their fundamental nature.

Intermediate (pink) muscle fibres
The idea of "pink muscle" comes from the anime series "Kenichi: The Mightiest Disciple", in which one of the masters, Akisame, is said to have converted all the muscle in his body into "pink muscle". In the show, it is described as a third type of muscle fibre, "in-between" the slow (red) and fast (white) twitch muscle fibres.
In reality, there are indeed three types of muscle fibres, with the third type being called "intermediate muscle fibres". These muscle fibres are very adaptable in the short and long term and can be influenced and manipulated to work well in any direction. They are found in all muscles, and their internal composition depends on how and how often the muscle is stressed.
The subtypes of intermediate muscle fibres depend on various aspects, including energy supply, colour, power potential, and contraction speed. It is believed that the distribution of the different fibre types is determined genetically, but research has shown that it is possible to transform this distribution through specific training.
While it is not possible to convert all muscle fibres to a single type, it is true that a lot of muscle fibres in untrained individuals are made up of hybrid types, which are two types of muscle fibres at once. Training increases specificity by creating more pure fibre types, and a 10% change in muscle fibre type would be considered impressive.

Muscle fibre conversion
The concept of "pink muscle" originates from the anime "Kenichi: The Mightiest Disciple", where one of the masters, Akisame, is said to have converted all the muscle in his body into "pink muscle". This type of muscle is described as a mix of slow (red) and fast (white) twitch muscle fibres, resulting in a perfect blend of explosiveness and endurance.
In reality, muscle fibres exist on a continuum, with slow fibres, fast fibres, and hybrid fibres exhibiting qualities of both slow and fast twitch. While it is believed that muscle fibre types are determined genetically, research has shown that it is possible to alter this distribution through specific training. For example, it is known that Type IIa (fast-twitch) muscle fibres can convert to Type IIx (super-fast twitch) and vice versa through training.
However, it is important to note that the complete conversion of all muscle fibres to a single type, especially Type IIa as depicted in the anime, is not possible. This is because our bodies require a balance of slow and fast-twitch muscle fibres for various functions. Slow-twitch muscles, for example, are essential for maintaining posture and performing basic movements like walking and running long distances.
While it is true that training can influence the composition of muscle fibres and improve speed and endurance, the extent of these changes is limited. Achieving a significant conversion, such as transforming all muscle fibres into a single type, is unrealistic. A more realistic expectation is a change of around 10%, which is still considered impressive and indicative of increased specificity and purity of fibre types.
In conclusion, while the concept of "pink muscle" as a perfect mix of slow and fast-twitch muscle fibres is intriguing, it remains within the realm of fiction. Our muscles require a mix of fibre types to function optimally, and any attempts to drastically alter this balance through training are unlikely to succeed.

Muscle fibre identification
Muscle fibres are broadly classified as slow oxidative (SO), fast oxidative (FO), and fast glycolytic (FG). However, there are further classifications based on the speed of contraction, colour, and power potential. Slow-twitch muscle fibres, also known as type 1 or red fibres, have a high oxygen content and are used for aerobic exercise. They obtain their energy from glycogen and fat and are used for endurance activities like long-distance running. On the other hand, fast-twitch muscle fibres, also known as type 2 or white fibres, have a lower oxygen content and gain their energy anaerobically from glycogen. They are used for powerful and rapid movements but fatigue quickly.
There are also intermediate muscle fibres that are very adaptable and can be influenced by training. These include type 2a fibres, which are a hybrid of type 1 and type 2b fibres. While it is possible to convert type 1 muscle fibres to type 2a, converting all muscle fibres to type 2a is not possible. This is because slow-twitch muscle fibres are essential for everyday movements like standing and walking, and they also help keep you upright.
The identification of muscle fibre types is important in understanding muscular disorders and the effects of ageing on muscles. For example, age-related loss of muscle mass is associated with a decrease in both type I and type II fibres, with a preferential atrophy of type II fibres. Diagnostic procedures for muscular disorders include testing creatine kinase levels, electromyography, muscle biopsy, and genetic testing.
In terms of specific identification methods, Western blot analysis and dot blotting are commonly used techniques. Western blot analysis involves probing for specific proteins in fibre segments, while dot blotting allows for rapid detection of fibre type before pooling of fibres. However, dot blotting is not recommended for assessing fibre-type distribution in a muscle biopsy due to the need for a large number of fibre segments and the potential for bias in selection. Another identification method is actin detection, which is abundant in both fast and slow-twitch muscle fibres.

Frequently asked questions
Pink muscle is a term used in the anime 'Kenichi: The Mightiest Disciple' to refer to a fictional type of muscle fiber. In the show, the character Akisame converts all the muscle in his body to this type of muscle fiber, which is said to be a mix of explosiveness and endurance.
No, it is not real and is entirely fictional. It is not possible to convert all your muscle fibers to a single type, especially type 2a, as this is a fast-twitch muscle fiber and the body needs a good amount of slow-twitch muscle fiber to function.
There are two main types of muscle fibers: slow-twitch (type 1) and fast-twitch (type 2). Slow-twitch muscle fibers are used for endurance and have high oxygen content, while fast-twitch muscle fibers contract quickly and are used for powerful movements. There are also intermediate muscle fibers that are very adaptable.
The only 100% accurate way to determine your muscle fiber type is through a muscle biopsy. However, a practical test that can be done in less than a minute is the vertical jump test.
While it is not possible to convert all your muscle fibers to a single type, it is possible to convert one type to another through specific training. For example, you can convert type 1 muscle fiber to type 2a, and a conversion of white into red muscle fibers has been observed.
