In follow up to article 1, I would like to better explain the three components of body build are type, size and composition. A system, developed by W.H. Sheldon (c.1940), uses the terms ectomorph, endomorph, or mesomorph to describe the body build of an individual.
There are three extremes of body types.
An endomorphic individual typically has short arms and legs and a large amount of mass on their frame. Their mass hampers their ability to compete in sports requiring high levels of agility or speed and perform sustained weight bearing aerobic activities such as running. Sports of pure strength like power lifting, are perfect for an endomorph. They can gain weight easily and lose condition quickly if training stops.
- Size benefits sports such as rugby where bulk is useful, provided it can be moved powerfully
- Tend to have large lung capacity which can make them suited to sports such as rowing
- They can increase muscle mass much more easily than ectomorphs
A mesomorphic individual excels in strength, agility, and speed. Their medium structure and height, along with their tendency to gain muscle and strength easily makes them a strong candidate for a top athlete in any sport. They can sustain low body fat levels and find it easy to lose and gain weight.
- Respond well to cardiovascular and resistance training
- Can sustain low body fat levels
- All muscle groups can be used to derive positive training adoption
- Dependent on the sports' needs they can easily gain or lose weight
A predominantly ectomorphic individual is long, slender and thin, and therefore power and strength sports are perhaps not suitable as their slight build leaves them susceptible to injuries. While they can easily get lean and hard, their lack of musculature severely limits their chances in sports requiring mass. Ectomorphs dominate endurance sports and gymnastics. They can archive low levels of body fat which can be detrimental to health and for females in endurance sports it can result in a cessation of periods and iron deficiency.
- Light frame makes them suited for aerobic activity like gymnastics
- Smaller body surface area also enhances their suitability for endurance activity
- Their body is better at thermo regulation, important in endurance based sports
Sheldon evaluated the degree a body type was present on a 1 to 7 scale where 1 is the minimum and 7 is the maximum.
All athletes are made up of the three extreme body types so we are all part endomorph, part mesomorph and part ectomorph. Using a score of one to seven, we can grade our bodies on each of the extreme body types. e.g. two, six, three means: two (low endomorphy); six (high mesomorphy); three (low ectomorphy). In this way, we can compare our body type with that of other athletes. This method of body typing is known as somatotyping - height is not taken into consideration.
The "perfect" bodybuilder would perhaps be a 173, while 475 might be better suited for football, and 147 a basketball player. Having scores in multiple body types, for instance the football player's 475, does not mean he has all of the traits of each body type mixed together. It may mean he has the heavy thick build of the Endomorph combined with superior musculature and strength of the Mesomorph, with the above average height of the Ectomorph.
Greek researchers evaluated 518 elite Greek basketball, volleyball and handball players. Their results indicated the following somatotypes (endomorph, mesomorph & ectomorph) for each sport:
Body size refers to the athlete's height and weight. The ideal size for an athlete depends on the sport or event and sometimes the position they play in their sport (consider the various body sizes in a Rugby team). There are standard ideal weight charts based on an individual's height.
Body composition refers to the athlete's body fat. In most sports, the athlete will try to keep his/her levels of body fat to a minimum. In general the higher the percentage of body fat the poorer the performance.
Alternative method of somatotyping
Researchby Barbara Heath et al. (1967) identifies an alternative somatotype method for both sexes and all ages.
