Fear stability, the effects of negative emotion on neuromuscular – control strategies after injury

The power of the mind, a critical determinant of muscle strength/weakness.
The fear is powerful emotional and cognitive response to a perceived threat, need neurocognitive strategies are required to regulate negative and emotions and neuromuscular control, because without this strategy it can lead to errors in the regulation of muscle activity, that is, it leads to JOINT RIGIDITY (loss of stability).

Identify, how can stimulate influence this effect, in the brain and muscle coordination in
patients after injury.

There are neuromechanical Relation among fear- cognitive and joint stability. The injuries are relation with neuromuscular control, so you need optimization this neuromuscular control to injuries prevention, joint stability and joint health on future

The optimum neuromuscular control, the central nervous system should be able to do precisely: reaction – action, through the neural pathways, so through of control – FEED FOWARD AND FEEDBACK is important during fast situations, they keep the stability.

Change processes are adaptive, they are generated by biochemical neurotransmitters, an important one is GABA ACID (INTERCORTICAL INHIBITOR), IT PLAYS AN IMPORTANT ROLE IN MOTOR CORTICAL PLASTICITY (learning), the motor control many actions are previously adjusted without doing the action in the premotor cortex, it is previously active than the action is going to be executed.
The nervous system is changing, he is not the same during whole life, the gray matter is removed, depending on the need.

Should consider:

  • Decrease excess inhibition.
    • Selective attention (optimizes the neural connection, increasing synapse efficiency and decreasing noise, inhibiting it)
    • external focus (facilitates the learning of motor tasks, increases strength, decreases energy expenditure, improves the action of perception of movement).
  • An interventional strategy that activates the motor cortical areas (Hetu et al. 2013)] attenuating the loss of muscle strength while concomitantly eliminating the prolongation of the corticospinal silent period [SP; a measure of corticospinal inhibition quantified via transcranial magnetic stimulation (TMS) (Kobayashi and Pascual-Leone 2003; Reis et al. 2008)].
  • (a neurophysiological outcome of corticospinal inhibition), coupled with the finding of 2) an association between the changes in strength and the corticospinal silent period provide strong support for the notion that the cortex is a critical determinant of muscle strength/weakness.
    High levels of stress can produce detrimental effects that make the athlete more vulnerable to injury (attention deficits, anticipated fatigue and exhaustion, etc.).
    This is because perhaps the different situations that cause us stress can lead to …
    Stress weakens the body’s immune system and makes it more vulnerable

    • That the athlete seeks the injury unconsciously as an escape valve from the stress situation in which he is subjected.
    • Stress causes high activation levels that reduce the athlete’s attention focus, or it can also cause attention deficits due to very low activation.
    • Stress can cause specific muscle overactivation that can hinder flexibility and motor coordination, hindering movements, increasing vulnerability to injury.
    • Stress can lead to the presence of aggressive uncontrolled behavior and physical risk.
    • Stress can cause athletes to seek control of stressful situations, leading to excess training that can be very harmful.
    • When physical exercise serves to alleviate stress symptoms unrelated to sports (for example work or family stress), it is common for quantitative or qualitative abuse to occur, increasing vulnerability to injury.
