Asymmetrical Neurological-Biological relationship leading to reactive strength injury. Notice the asymmetry of how the top-down neurology is larger than the bottom-up biology.

Neurological Asymmetry: A Mechanism of Reactive Strength Injury

When we understand strength as an emergent behavior, it is simple for us to see there is a top-down neurological component and a bottom-up biological component of every strength output. Our belief is that the top-down neurological component can almost infinitely scale up in connectivity and does so at a faster pace than the biology. The image shows how when an injury is biological in nature to the athlete, for example, a hamstring strain, a mechanism of injury is going to be that top-down neurology has scaled up more than the bottom-up biology of the hamstrings.

Reactive Strength Injuries

Reactive strength injuries can involve the connective tissue of various muscles, tendons, and ligaments throughout the body. Here's a list of some common reactive strength injuries:

  • Hamstring strain or tear

  • Achilles tendon strain or rupture

  • Anterior Cruciate Ligament (ACL) tear

  • Medial Cruciate Ligament (MCL) tear

  • Lateral Epicondylitis (Tennis elbow)

  • Medial Epicondylitis (Golfer's elbow)

  • Patellar tendonitis (jumper's knee)

  • Any tendinitis or tendinosis
