The size and number of motor units being stimulated
One muscle fibre contracting maximally
The opposing muscles relaxing
Size of the stimulus
The strength of muscle fibre contraction depends on the size of the stimulus
A muscle fibre either contracts maximally or not at all
For a muscle to contract, its opposing muscle must relax
A strong muscle contraction is needed for coordinated movement to occur
Increase in type I muscle fibres and improved resistance to fatigue
Frequency of nerve impulses to motor units increase
Improved protein storage and availability as a fuel for exercise
Reduced synchronous recruitment of motor units
Increased stroke volume, cardiac output and heart rate
Strengthening/growing new connections within the nervous system
Speeding up the frequency of nerve impulses to the motor units
Improved synchronous recruitment of motor units resulting in stronger muscle contractions
Enhancing the growth of new connections within the nervous system
Increasing the proportion of type II muscle fibres
Improving the ability to store glycogen and fat as fuels for exercise
Reducing synchronous recruitment of motor units
