Intermuscular Coordination
Intermuscular Coordination: Optimal timing and motor unit recruitment of the prime mover, agonists, antagonists, synergists, neutralizers, stabilizers and fixators.
Example: Hip Extension (for example, during a Deadlift with Posterior Pull )
- Prime Mover: Gluteus maximus
- Synergists: Biceps femoris (long head), semitendinosus, semimembranosus, posterior head of adductor magnus
- Antagonists: Psoas, iliacus, tensor fascia latae (TFL), rectus femoris, anterior adductors (especially pectineus), sartorius
- Neutralizers: Gluteus minimus and anterior fibers of gluteus medius neutralize external rotation force of gluteus maximus
- Stabilizers: Deep rotators of hip
- Fixators: Intrinsic stabilization subsystem, rectus abdominis, internal and external obliques, quadratus lumborum, erector spinae
