Somatotype

Somatotype is a taxonomy created in the 1940s by American psychologist William Herbert Sheldon to categorise the human physique based on the relative contribution of three fundamental elements he called somatotypes, which he categorised as 'ectomorph, mesomorphic, and endomorphic. Let us discuss these ecto endo mesomorphs in detail.

Body Somatotypes

Ecto endo mesomorphs are the different body types. These terms are widely used in physical education.

1. Ectomorph Body Type

A standard skinny guy is an ectomorph. Ectos have a slim build, narrow joints, and a lot of muscle. Ectomorphs usually have long, slender limbs with stringy muscles. Shoulders are usually narrow and small.

Typical Traits of an Ectomorph:

• Ectomorphs are people whose bone structure and frame are small and "delicate."

• Typical "hardgainer".

• a chest that is flat.

• Shoulders that are small.

• slender.

• Muscle mass is a measure of how fit you are.

• Has a hard time gaining weight.

• a fast metabolism.

Ectomorphs have a hard time gaining weight. They have a high metabolism, which allows them to burn calories quickly. To gain weight, Ectos require a large amount of calories. Short, intense workouts focusing on large muscle groups are recommended. Supplements are strongly suggested. Ectomorphs should feed before going to bed to avoid muscle catabolism. Ectomorphs, on the whole, have an easy time losing weight, which makes cutting back to lean muscle easier for them.

2. Mesomorph Body Type

A mesomorph is characterised by massive bones, muscles, and a naturally athletic physique. The ideal body form for bodybuilding is the mesomorph. It is easy for them to gain and lose weight. They are naturally solid, which provides the ideal foundation for muscle growth.

Typical Traits on a Mesomorph Body Type:

Sportsmanship.

The body is generally tough.

Muscles with fixed definition.

easily Gains Muscle.

Rectangular shaped body.

It is easier for endomorphs to gain weight than it is for ectomorphs.

Weight training works well for the mesomorph body form. Gains are typically noticeable right away, particularly for beginners. The disadvantage of mesomorphs is that they gain weight more quickly than ectomorphs. This means they'll have to keep an eye on their calorie intake. For mesomorphs, a combination of weight training and cardio is usually the most effective.

3. Endomorph Body Type

Endomorphs have a robust and generally soft body shape. Endomorphs are prone to gaining weight quickly. Endos are usually smaller in stature, with thick arms and legs. The muscles in the upper legs, in particular, are powerful. Endomorphs notice that leg movements like the squat come easily to them.

Typical Traits of an Endomorph Body Type:

• The body is round and soft.

• It's really easy for him to gain muscle and fat.

• Is usually brief.

• "Stocky" construction.

• The shape of your body is round.

• It's difficult for him to lose weight.

• Metabolism is slow.

• Muscles aren't as well described as they should be.

Endomorphs have a simple time gaining weight when it comes to exercise. Unfortunately, the majority of this weight is made up of fat rather than muscle. Endomorphs must both train cardio as well as weights to keep fat gain to a minimum. Supplements are usually unnecessary if a person consumes a lot of protein in their diet.

Somatotype Test

Somatotype tests can be done by going to a lab and getting your body fat, bone, and muscle mass tested to determine whether you're an ectomorph, mesomorph, endomorph, or a combination form. There are different types of methods used for testing somatotype, one of the commonly used methods is the heath carter method. The Heath-Carter measurement system is most widely used to determine somatotype, in which scores for endomorphy, mesomorphy, and ectomorph are determined using different anthropometric measurements and, in some cases, standardised images (photoscopic method) are used.

Someone is usually rated on a scale of 1 to 7 in each of the three categories (though higher ratings are possible), though you cannot score highly in all three. The endomorphy score comes first, followed by mesomorphy, and finally ectomorph, to yield a somatotype number. The somatotype can also be represented on a two-dimensional scale using a shield diagram or somatograph.

Health Carter Method For Measuring Somatotype

The Heath-Carter somatotyping approach is the most widely used today. The somatotype can be obtained in three ways.

(1) The anthropometric process, in which the criterion is estimated using anthropometry.

(2) The photoscopic process, which involves assigning ratings to a standardised image.

(3) The criterion method is an anthropometric plus photoscopic method that combines anthropometry with ratings from an image.

The anthropometric approach has proved to be the most effective for a number of applications since most people do not have the ability to become criterion raters using photographs.

The Heath-Carter anthropometric somatotype is calculated objectively, but the rating's validity is determined by the accuracy of the measurements used. The measurements' test-retest reliability should be recorded by the researchers. The means should not vary substantially when comparing the distributions of two independent variables on the same topics, and the Pearson product-moment r should be greater than 0.90. Height and weight, in particular, should have r = 0.98 test-retest values. The r value for girths and diameters should be between 0.92 and 0.98. R's of 0.90 to 0.98 are appropriate for skinfolds. 

Many anthropometrics currently use the technical error of measurement (TEM) to assess the accuracy, or precision, of the measurer on a particular variable. The square root of the difference between measures one and two squared, separated by twice the number of subjects, is the TEM (Cameron, 1984, Norton and Olds, 1996). The TEM gives you an approximation of the measurement error in the variable's units of measurement. 

This value means that a calculation should be within +/- of the TEM two-thirds of the time. The TEM can be expressed as a percentage of the total number of measures measured (grand mean). This enables comparisons between measures or between classes of variables. Skinfolds should have a TEM of about 5%, breadths and girths should have a TEM of 1%, and height should have a TEM of about 0.5 percent.

Sheldon’s Somatotypes Theory

Sheldon classified people according to three body types, or somatotypes. These sheldon body type are: 

• Endomorphs, who are rounded and delicate, have a reputation for having a "viscerotonic" personality (i.e., relaxed, comfortable, extroverted).

• Mesomorphs, who are square and muscular, have a “somotonic” disposition, according to legend (i.e., active, dynamic, assertive, aggressive).

• Ectomorphs, who are slender and fine-boned, are considered to have a “cerebrotonic” disposition (i.e., introverted, thoughtful, inhibited, sensitive). 

He later used this system to describe delinquent behaviour, discovering that delinquents were more likely to be high in mesomorphy and low in ectomorph, and suggesting that mesomorphy's related temperaments (active and violent but deficient in sensitivity and inhibition) appear to trigger delinquency and criminal behaviour. His study was criticised because his samples were not representative and he mistook correlation for causation, despite the fact that it was revolutionary.

Did You Know

• Somatotyping is useful in sports where body shape has the potential to affect results. The aim of this research was to determine the somatotype of high-profile Lithuanian athletes in kayaking, basketball, and football, and to compare them to low-level athletes of the same age in each discipline.

• Men's endomorphic mesomorph and women's mesomorph-endomorph were the most popular somatotypes.
