Description

Mexican Serape.jpg

The term serape originates from Mexico, it is a form of cloth that looks like a long blanket-like shawl worn by Mexicans.

There are a group of muscles, in the body, that attach together by fascia forming the same shape of the serape .[1]

These muscles when working together create a give a high force during ballistic motions, such as throwing or kicking.That is why the power they generate is known as the serape effect.

Muscles of the Serape[1]

  • Ipsilateral Rhomboids
  • Ipsilateral Serratus anterior
  • Ipsilateral external abdominal obliques
  • Contralateral Internal abdominal obliques
  • Contralateral adductors

Serratus anterior has a direct attachment to external abdominal obliques. Therefore during rehabilitation to increase firing of Serratus anterior activation of the abdominal muscles and rotation causing stretching and a snap back effect, for example as in push ups, the bird dog exercise, and turn wall punch exercise[2]

It also applies to the adductors, particularly adductor longus. Adductor longus has a direct attachment to the contralateral external abdominal oblique and ipsilateral internal abdominal obliques. Therefore using isometric hip adduction will recruit more abdominal muscles during plank exercises [3]

Advantage

  • The serape effect will allow the athlete to generate a high force, ballistic movements in both the upper limb and lower limb. This is achieved by activating the trunk muscles and adding rotation to the upper or lower limbs. These movements act as a spring; when stretched the muscles will store potential energy which will be converted into kinetic energy during motion, this energy will be transmitted to the extremities,
  • Serape can be used during rehabilitation to achieve an advantage wherein weak or inhibited can be assisted by other muscles facilitating a stronger movement.
