It is a simple measure that is important in the anthropometrical profiling of athletes in many sports in which reach is important, such as rowing, swimming and basketball.

You should measure from fingertip to fingertip and not have a flat hand as in this photo. When measuring the individuals forearm, we used our own judgment to determine where the forearm bone began. It is possible that these measurements were incorrect and affected the calculation of the proportion.

Students collect data by observing and measuring using the metric system and recognize differences between observed and measured data. Most sports that involve catching and throwing a ball, like baseball, cricket, or soccer, will be more accessible since people with long arms have a more extended reach, making it easier for them to catch. They can also throw a ball faster and farther since they can generate more centrifugal force. Ape index is the ratio of arm span relative to their height.

By 10 years of age, AS is equal to height; and after 10 years in boys and 12 years in girls, AS exceeds height by up to 5 cm. If AS is greater than 5 cm, pathologic causes of tall stature such as Marfan’s Syndrome or hypogonadism should be considered.

In the case of both wingspan and height being 180 cm, the ape index will be 0. The typical wingspan to height ratio is right around 1.
