FRC Neurological Adaptations and Motor Control Flashcards

What role do mechanoreceptors play in the FRC training model?

Answer: They sense mechanical stimuli such as pressure and joint position to inform the nervous system

Mechanoreceptors in and around joints detect mechanical stimuli and relay position and movement information to the nervous system, forming the basis for proprioceptive awareness in FRC.

In FRC, what is the significance of training at 'end range' positions?

Answer: End range training builds neurological control where the nervous system is weakest

Training at end ranges of motion strengthens the nervous system's ability to control and produce force in positions where neurological control is typically underdeveloped.

Which FRC tool uses sustained isometric contractions at end range to expand usable range of motion?

Answer: Progressive Angular Isometric Loading (PAILs) and Regressive Angular Isometric Loading (RAILs)

PAILs and RAILs use isometric contractions at end range to stimulate neurological adaptations and increase the nervous system's tolerance and control of new ranges.

What neurological adaptation is primarily responsible for increased flexibility gains seen after consistent FRC practice?

Answer: Reduced neural inhibition and improved motor mapping at newly acquired ranges

FRC-driven flexibility improvements are largely neurological; the nervous system reduces protective inhibition and builds new motor maps as it gains confidence in controlling expanded ranges.

How does the concept of 'segmental stabilization' relate to neurological control in FRC?

Answer: It involves the nervous system's ability to isolate and control individual joint segments independently

Segmental stabilization in FRC refers to developing the nervous system's capacity to independently control each joint segment, ensuring movement quality and injury prevention.

In FRC, what does the term 'irradiation' describe in the context of neurological training?

Answer: The spread of neural tension from a maximally contracted muscle group to stabilize surrounding structures

Irradiation describes how maximal muscular contraction in one area spreads neural drive to adjacent structures, increasing stability and improving control during end-range loading.
