Chicken meat is indeed a muscle. The poultry meat we eat is skeletal muscle, to be precise. Chicken meat is made up of two basic types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements, such as standing. The colour and flavour of dark meat are due to a protein called myoglobin, which promotes more oxygen and blood flow to the muscle.

Chicken meat is made up of two types of muscle fibres: white and red
Meat is muscle, and chicken meat is no exception. Chicken meat is made up of two types of muscle fibres: white and red. These are also referred to as white meat and dark meat, respectively. White meat is found in the breasts and wings of the chicken, while dark meat is found in the legs, thighs, and drumsticks.
White muscle fibres are used for short, quick movements, while red muscle fibres are used for prolonged movements, such as standing. Chickens stand for most of the day, and their leg muscles are used for walking, so these muscles are more active. The higher activity of the leg muscles increases the muscles' need for oxygen. The darker colour of more active muscles comes from a chemical compound in the muscle called myoglobin, which is important for oxygen transport. Myoglobin is purple and full of iron.
White fibres rapidly convert carbohydrates from within the fibres themselves into energy, whereas red fibres are fuelled by fat, some of which comes from within the fibres and some of which comes from the bloodstream. Dark meat has a higher fat content than white meat, which gives it more flavour. It also contains higher levels of zinc, iron, vitamin C, and niacin (vitamin B-3). White meat, on the other hand, has more B vitamins, specifically pyridoxine (vitamin B-6).
In terms of cooking, white meat dries out more easily and is best for broiling, sauteing, stir-frying, grilling, and other quick methods. Dark meat is fattier and juicier, and it is almost impossible to overcook. Roasting, braising, and frying are great options for dark meat.

White meat comes from the breast and wings, and red meat from the thighs and drumsticks
Chicken meat is indeed muscle. The meat is made up of two basic types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements, such as standing.
White meat comes from the breast and wings of a chicken, whereas red meat comes from the thighs and drumsticks. White meat is considered lean and mild in flavour, and dries out easily if overcooked. It is also the most popular and expensive cut of chicken. It contains about 10% red fibres, and has a little more protein than dark meat.
Red meat, on the other hand, is found in the legs of the bird, which are the thighs and drumsticks. It contains around 50% red fibres and is more flavourful and juicy. It can be cooked longer and is almost impossible to overcook. The muscles are tougher and need a longer cooking time to tenderise. It has a higher fat content and more than twice the amount of saturated fat.
Both types of meat are packed with protein and can be part of a healthy diet. They also contain many vitamins and minerals, such as zinc and B vitamins.

White fibres are used for short, quick movements, and red fibres for prolonged movements
Chicken meat is indeed muscle. Chicken meat is made up of two basic types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements, such as standing.
White muscle fibres rapidly convert carbohydrates from within the fibres themselves into energy, whereas red muscle fibres are fuelled by fat, some of which comes from within the fibres and some of which comes from the bloodstream. Red muscle fibres get their colour from the proteins that help convert this fat into energy, such as myoglobin, which is purple and full of iron. Myoglobin is a red pigment, similar to the hemoglobin in red blood cells, that improves the delivery of oxygen to the slow-twitch fibres.
In humans, fast-twitch muscle fibres are the muscle cells responsible for short, powerful movements. They are also called white fibres or type II fibres. They are built for quick, powerful movements, compared to slow-twitch muscle fibres, which are more suited to endurance activities. Type II fibres can be further divided into type IIa and type IIx, the latter of which is better at providing force but fatigues faster, making them inefficient.
In chickens, muscles containing mostly white fibres are referred to as white meat, and muscles with more red fibres are referred to as dark meat. White meat, found in the breasts and wings, contains about 10% red fibres. This part of the chicken is lean and mild in flavour, and dries out easily if overcooked. Dark meat chicken contains around 50% red fibres and is found in chicken legs, which are more flavourful and juicy, and can be cooked longer. Light meat contains slightly fewer calories than dark meat, which has a higher fat content.

White meat is leaner and dries out easily, while dark meat is fattier and juicier
Chicken meat is made up of two types of muscle fibres: white fibres, used for short, quick movements, and red fibres, used for prolonged movements such as standing. White meat, found in the breasts and wings, contains about 10% red fibres. It is lean and mild in flavour, and dries out easily if overcooked. White meat is a good choice for those following a low-fat, heart-healthy diet.
Dark meat, on the other hand, contains around 50% red fibres and is found in chicken legs, thighs, and drumsticks. It is more flavourful and juicy, and can be cooked longer. Dark meat is great for roasting, braising, and frying, as the extra fat melts when exposed to heat, keeping the meat juicy. The reddish colour of the dark meat turns brown when cooked.
The difference in colour and flavour between white and dark meat is due to a protein called myoglobin, which promotes more oxygen and blood flow to the muscle. Myoglobin is purple and full of iron, and it gives red muscle fibres their colour.
Both types of meat are packed with protein and can be part of a healthy diet. White meat has more protein per serving, while dark meat contains more total fat, saturated fat, and sodium, which gives it a fattier and juicier mouthfeel. Dark meat also provides more micronutrients like iron, zinc, and riboflavin (vitamin B2). On the other hand, white meat has more phosphorus, vitamin B12, niacin (vitamin B3), and vitamin B6.

Dark meat contains more iron, zinc and vitamin C, while white meat has more B vitamins
Chicken meat is primarily muscle. It is made up of two basic types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements, such as standing. White muscle fibres rapidly convert carbohydrates from within the fibres themselves into energy, whereas red muscle fibres are fuelled by fat, some of which comes from the bloodstream.
When it comes to chicken, muscles containing mostly white fibres are referred to as white meat, and muscles containing more red fibres are referred to as dark meat. White meat, found in the breasts and wings, contains about 10% red fibres. This part of the chicken is lean and mild in flavour, and dries out easily if overcooked. Broiling, sauteing, stir-frying, grilling, and other quick methods are best for cooking white meat. Dark meat, on the other hand, contains around 50% red fibres and is found in chicken legs, thighs, and drumsticks. It is more flavourful and juicy, and can be cooked longer using methods such as roasting, braising, and frying. The muscles in dark meat are tougher and need a longer cooking time to tenderise, and the extra fat melts when exposed to heat, keeping the meat juicy.
Dark meat contains higher levels of zinc, iron, and vitamin C, while white meat has more B vitamins, specifically niacin (vitamin B-3) and pyridoxine (vitamin B-6). Dark meat also has a higher fat content, with almost 3 extra grams of fat per 100 grams of meat, and more than twice the amount of saturated fat. White meat, on the other hand, contains slightly fewer calories and has a little more protein.
While white meat is often considered the healthiest part of the chicken, eating a variety of both white and dark meat will ensure you get the full range of flavours and nutrients that chicken has to offer.

Frequently asked questions
Yes, the poultry meat we eat is skeletal muscle. Chicken meat is made up of two basic types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements, such as standing.
White meat refers to the breast and wing portions of the chicken. This cut of protein tends to be incredibly lean and has a notable pale (white) colour when cooked without seasoning. White meat has less fat and more protein than dark meat.
Dark meat comes from the thigh and drumstick (the legs of the bird). Because chickens stand most of the time and use their legs quite often, these two cuts of meat tend to contain the highest amount of myoglobin, making them redder in pigment. Dark meat has a higher fat content and more flavour than white meat.
Light meat tastes milder, whereas dark meat is fattier and tastes more chicken-y.
Green muscle disease, or deep pectoral myopathy (DPM), involves the death of a part of the breast tenderloin (minor pectoral muscles), which results in yellowish-green tissue. It is believed to be caused by the vigorous activity of the breast muscles.
