Neuromuscular coordination refers to the ability of the nervous system to effectively recruit muscles to perform specific tasks and is essential for motor control. It operates on intermuscular and intramuscular levels, involving the interaction between muscle groups and individual muscle fibers, influenced by factors such as rate coding, recruitment of motor units, and synchronization. The mechanisms include contributions from the cerebral cortex, motor pathways, cerebellum, and proprioceptors, alongside exercises designed to enhance coordination.

2. DEFINITION:
 Neuromuscular Coordiantion is the
coordination between nerves and muscles.
 It is also known as “Motor Control”.
 Neuromuscular coordination relates to the
ability of nervous system to efficiently
recruit a muscle or group of muscles in
order to perform a specific task

3. Neuromuscular Coordination
Works On Two Levels
Intermuscular
Coordination
Intramuscular
Coordination

4. Relates to the interaction between
muscles group(Agonist,
Antagonist,fixators and
neutralizers) while performing a
specific task or activity.
The greater the level of
coordination between different
muscles groups the better.
INTERMUSCULAR COORDINATION

5. Bicep curls;

6. INTRAMUSCULAR COORDINATION
 Is the activation of individual neuromuscular
units within a singe muscle fibre.
 The activation of muscle fibre is dependent on
:
1. Rate Coding( “Firing rate” of action potential)
2. Recuitment of neuro muscular motor units
3. Synchronization of motor units

7. • RATECODING
It is the firing rate of neurouscular
control units which in return
increases the strength of muscle
contraction.
When action

8. Muscle AP (cont.)
• Spread of the AP via Transverse Tubules
Fig. 7.5 Transverse (T) tubule-
sarcoplamic reticulum system

9. Fig. 7.7 Excitation-contraction coupling in the muscle showing (1) an AP that causes the release of Ca ions from the
sarcoplasmic reticulum and then (2) re-uptake of the calcium ions by the calcium pump.

10. • RECRUITMENT OF
NEUROMUSCULAR MOTOR
UNITS
 By working against
resistance,muscles can recruit
mOre motor units to overcome
resistance.
 It could be increased by :
1. Maximum load training
OR
1. Plyometric training

11. CONT….
Motor neurons innervate muscle fibers
Motor end plate is where they meet
Neurotransmitters are released by
nerve signal: this initiates calcium ion
release and muscle contraction
Motor Unit: a motor neuron and all the muscle fibers it innervates (these all
contract together)

12. • PLYOMETRIC TRAINING
Excercises in which muscles
exert maximum force in
short interval of time.
Its goal is to increase
muscle power.

13. • SYNCHRONIZATIONOFMOTORUNITS
The process refers to the summation of motor
unit while performing an activity.The degree of
summation of motor unit is influenced by
when more and more units being stimulated.
It can be enhance during ;
1. Strenght training programmes

15. • STRENGTH TRAINING
PROGRAMMES

16. MECHANISM OF
NEUROMUSCUAR
COORDINATION
Mechanism of neuromuscuar
coordination comprises on 4
leves;
1. The cerebelum cortex
2. The motor pathway
3. The cerebellum
4. Kinaesthetic sensation
Motor Unit: a motor neuron and all the muscle fibers it innervates (these all
contract together)

17. MECHANISM OF
NEUROMUSCULAR CO-
ORDINATION
1. THE CEREBRAL CORTEX :
Voluntary movement is initiated in response to sensory
stimulus.An initiation centre exist in the brainstem
which alert the cerebral cortex which then is
responsible for planning the pattern of movement.
2.THE MOTOR PATHWAY :
The action of each muscle group is determined by the
afferent impulses which reach it by the motor pathways.

18. Cont..
3.THE CEREBELLUM :
The cerebellum is a receiving station of information which
reaches it by the afferent pathways conveying impulses of
kinesthetic sensation from the periphery and from other parts
of the brain.
4.KINAESTHETIC SENSATION :
The afferent impulses of kinaesthetic sensation arise from
proprioceptors situated in muscles tendons and joints and
they record contraction or stretching of muscles and the
knowledge of movement and positions of limb

19. EXERCISES RELATED TO
NEUROMAUSCULAR
COORDINATION
Exercises that improve the brain
body connection with coordinated
movement :
1. SHOOTING BASKETBALL
2. WALKING BACKWARD
3. SIDE-STEPPING
4. KARATE KICK ON ONE LEG

20. WALKING BACKWARD

21. SIDE STEPPING

22. KARATE KICKS ON ONE LEG
