Pronunciation: [mˌɛsəmˈɔːfɪk] (IPA) 
Mesomorphic is a word that describes a body type that is muscular, with a low body fat percentage. The spelling of the word is based on the prefix "meso-", meaning middle, and the suffix "-morph", meaning form. The first syllable in "meso-" is pronounced as /ˈmɛs/ and the second syllable has the vowel sound of /ə/. The stressing of the word falls on the second syllable, making it /mɛsəʊˈmɔːfɪk/ in IPA phonetic transcription.
Mesomorphic is an adjective used to describe an individual's physical body type or build. It refers to a specific somatotype that is characterized by a well-developed, muscular physique. Mesomorphs tend to have broader shoulders, a narrow waist, and solid bone structure. They are typically seen as athletically built and have a predisposition towards building and maintaining muscle mass.
The term "mesomorphic" originates from the concept of somatotyping, which was developed by William H. Sheldon in the 1940s. Somatotyping is the categorization of individuals into three main body types: ectomorphs, endomorphs, and mesomorphs. Mesomorphic individuals fall between the ectomorph and endomorph body types, possessing a combination of muscle and a relatively lean body composition.
In addition to their physical attributes, mesomorphs are often characterized by their overall physical strength, agility, and ability to excel in sports and physical activities requiring power and speed. They are known to have a higher metabolic rate, which facilitates easier muscle gain and maintenance. Mesomorphic body types are considered fortunate by some, as they are thought to have a natural advantage in achieving an aesthetically pleasing and athletic physique.
It is vital to remember that somatotyping is a general classification system, and individuals may display characteristics from multiple body types or exhibit variations within their own body type. Mesomorphic individuals often require tailored exercise and dietary plans that align with their specific needs to maximize their athletic potential and overall health.
The word "mesomorphic" is derived from two Greek roots: "meso" meaning "middle" or "intermediate", and "morphē" meaning "shape" or "form".
In the context of human body types, "mesomorphic" refers to individuals who are characterized by a medium build with well-developed musculature, moderate fat levels, and a naturally athletic physique. This classification is one of the three somatotypes (alongside ectomorph and endomorph) proposed by American psychologist William H. Sheldon in the 1940s, based on his observations of body structure and personality traits.
