Serape Draped loosely and crosses over the

front of the body in an “x” shape

The concept has been translated to muscle function reinforcing the muscles of the core as a connector

The serape muscles are considered

to include: the rhomboids, serratus anterior,

external obliques and internal obliques

Serape Effect

In ballistic actions such as throwing and kicking, the serape muscles add to the summation of internal forces. They also transfer internal force from a large body segment, the trunk, to relatively smaller body parts, the limbs

Preventing Injuries in Throwers with the Core and Hips

LE Flexibility (Used as part of an overall warm-up)Ipsilateral hip extension

Hip IR/ER (Lack of IR will force truck to open early and increase stress on medialElbow and /or anterior shoulder)

Core Training for Throwers Abdominal Bracing /Drawing in maneuver

Prone Cobra ProgressionLE Balance/Proprioception*

Standing Pulls - ant/post/lat pull (Weak gluts cause the hip to drop leading to drop of shoulder)LE Functional Strength Training**

Wind-Up/Lunge with twist Lunge with twist

Step-Ups with twist*Functional exercise that is multiplanar, incorporates the lumbo-pelvic-hip core

complex and can be challenged with proprioceptive input from unstable surfaces,eyes closed, etc

** Lunge strength will help deceleration injuries to the shoulder
