INSIGHT

Two Camps In The ROM Debate

  • The debate split into a 'stretch' camp and a neuromechanical-matching camp.
  • That polarization oversimplifies a nuanced evidence base and real-world coaching experience.
ADVICE

Maximize Recoverable Volume (MRV)

  • Prioritize maximizing recoverable volume (MRV) when designing programs for growth.
  • Add shortened/squeeze exercises to raise MRV and reduce joint stress as you advance.

Why The Brain Chooses Muscles

  • Neuromechanical matching means the CNS activates muscles with more favorable leverage at given joint angles.
  • This explains why some muscles show higher EMG in the stretch and others do not.
